BOSTON – Patients with rosacea, particularly the erythrotelangiectatic form, are considered good candidates for treatment with lasers and light therapies, but for acne, treatments with these therapies are still in the development stage.

For acne, treatments that are being studied include those that target the sebaceous glands, according to Mathew M. Avram, MD, who spoke about laser and light therapies for acne and rosacea at the American Academy of Dermatology summer meeting.

Light therapies for rosacea

Oxyhemoglobin in the blood absorbs light from lasers at wavelengths of about 595 nm (pulsed dye laser) and 532 nm (KTP laser), creating heat that helps destroy capillaries that contribute to the appearance of rosacea. Over a period of 3-4 weeks, the vessels are resorbed, and facial redness diminishes.

Patients with rosacea that are expected to do best with laser therapy are those with telangiectasia. Laser therapy is also effective for background redness but will be less effective for people with the papules associated with rosacea and “almost not effective at all for preventing flushing,” Dr. Avram said in an interview at the meeting.

Intense pulsed light (IPL) is another modality for treating rosacea. As with lasers, the mode of action is heating of certain structures and chromophores, causing their destruction and resorption, but unlike lasers, IPL output is broad spectrum and can be modified using filters.

With IPL, “basically, the endpoint that you want to see is transient purpural change, just a fleeting period of some black and blue, or if you’re treating vessels, you want to see vessel clearance when you’re firing the laser or the intense pulsed light,” said Dr. Avram, director of the Massachusetts General Hospital Dermatology Laser & Cosmetic Center, Boston.

On-screen settings of laser or IPL devices are essential, “but ultimately, if you want to have an effective treatment you really have to see what’s happening to your target … you need to pay attention to clinical endpoints, which is seeing that black and blue or that vessel clearance, not just paying attention to what’s on the screen.”

With IPL, too much pressure can compress vessels and blanch the skin, resulting in a less effective treatment, he added. He noted that tissue graying, whitening, or contraction indicates overly aggressive treatment, with the risk of scarring.

Certain factors can reduce the efficacy of IPL treatments of rosacea. Dr. Avram recommended against treating tanned skin and pointed out that anemic patients may benefit less from this approach since less hemoglobin presents a less-absorptive target for the treatments. He also advised particular caution when treating darker skin phototypes. But the most common factor that may make these treatments less effective is when a patient is on any type of anticoagulant, including NSAIDs or warfarin (Coumadin), because the mechanism of action is immediate microvascular hemorrhage, thrombosis, and eventual resorption.

For best results, Dr. Avram advises “appropriate overlap with the laser” to get an even and uniform improvement in the redness, with about a 15% overlap. Spacing laser spots too far apart can result in “foot printing,” the appearance of clearance in the areas of the laser pulse, but not in areas immediately around it “so it looks almost polka dotted.” After treatments, all patients should avoid the sun, he added.

What’s ahead for acne treatment

Until now, laser and light-based treatments for acne, “have provided inconsistent benefits for patients and all too often disappointing results,” Dr. Avram said in the interview. But several developments on the horizon may offer more effective therapies based on completely different technologies than are currently available. “Each of these therapies will be targeting the sebaceous glands in order to provide improved treatment for acne.”

One is a cryolysis device that uses cooling to selectively target lipids in the sebaceous glands. (Cryolysis is similar to cryolipolysis, which uses cooling to target fat cells.) The lipid-filled adipocytes are more sensitive to cold than is the water-rich dermis, thereby preserving the surrounding structures. There are also laser wavelengths that are absorbed by lipids, one of which is at about 1720 nm. In this case, heating rather than cooling targets the lipids.

Another technology in development is the use of nanoparticles coated with elements such as gold that are massaged through the skin into the sebaceous glands. Laser treatment with multiple different wavelengths targets the nanoparticles, heating them within the sebaceous glands, resulting in improvements in acne. In this case, treatment does not depend on the absorption spectrum of lipids. Clinical trials of this approach are now underway.

It is too early to tell which of these technologies is going to be effective or what potential side effects may occur. “However, the exciting news is that there will be multiple different technologies” designed to improve acne by targeting the sebaceous gland, and there is “the promise of potentially more effective noninvasive treatments that don’t require topical medications or oral medications,” Dr. Avram said.

For these potential new treatments, some objective outcome measure is needed to judge their efficacy. Right now, all that can be said is that they target the sebaceous gland, and clinical work still needs to be done to determine whether they will be effective, the degree of effectiveness, and how to optimize treatment, he noted.

Dr. Avram reported financial relationships with Cytrellis Biosystems, Invasix, Kythera, Masters of Aesthetics, Sciton, Zalea, and Zeltiq Aesthetics.

BOSTON – Surgery is the standard of care for most skin cancers, but nonsurgical and adjuvant treatments can be good options for certain skin cancers when surgery would be neither curative nor feasible, according to Anthony Rossi, MD.

“Whether you’re treating a superficial basal cell or superficial squamous cell carcinoma, I think first and foremost, if you’re going to use nonsurgical treatment options, it’s important to have a good biopsy diagnosis,” Dr. Rossi said at the American Academy of Dermatology summer meeting. He also advised that the biopsy capture the entire lesion or a good portion of it to get a good representation. “You don’t want to be surprised by any hiding, high-risk subtypes,” said Dr. Rossi, of the Memorial Sloan Kettering Cancer Center in New York.

Deciding on a nonsurgical treatment option should be based on knowing the patient. For example, know the patient’s concerns about cosmetic deformities, willingness to undergo surgery or not, and ability and willingness to do follow-up self-care.

For superficial basal cell or squamous cell carcinomas in situ and even lentigo maligna in situ not amenable to surgery, imiquimod may be an appropriate treatment. Dr. Rossi said his practice is to use it in an incremental fashion, starting with application five times per week, going to every day if there is no response after 1 to 2 weeks. If the response remains inadequate, he recommended adding a topical retinoid, such as tazarotene, in an effort to increase penetration.

For basal cell carcinomas and squamous cell carcinoma in situ, he uses imiquimod for a total of 6 to 8 weeks, starting from the time of the first reaction. For melanoma in situ, he uses it for more than 60 applications (12 weeks).

To show patients where they should be applying any topical treatment, Dr. Rossi marks the skin, photographs it, and prints out a picture for the patient. Sometimes he uses the patient’s phone to take the picture. For a basal cell or squamous cell carcinoma in situ, he indicates an area at least 5 to 10 mm beyond the margin of the tumor. The area is even larger for melanomas.

Dr. Rossi studies confocal microscopy to detect skin cancers. He uses it before treating a lesion to define the clinical boundaries of the lesion and the boundaries for the nonsurgical treatments, and then he uses it on follow up to look for any recurrences.

New anti-tumor agents

Two oral inhibitors of the sonic hedgehog pathway have been approved within the past 5 years for locally advanced or metastatic basal cell carcinomas. “In the right person, they can be quite beneficial if surgery would leave them with a very large cosmetic deformity or if surgery would be not curative,” Dr. Rossi said. “We’re seeing good results” with acceptable adverse events, specifically taste disturbances, muscle cramps, and hair loss. The first such drug, vismodegib (Erivedge), was approved in 2012, and sonidegib (Odomzo) came on the market about 1 year ago.

Besides oral agents, photodynamic therapy (PDT) with photosensitizers are another option for certain skin tumors. Dr. Rossi said his practice is to keep the treatment room fairly warm to assure good blood flow to the skin and thus good penetration of the drug. Because PDT acts by generating singlet oxygen to kill tumors, good blood flow to the tumor is necessary. To minimize discomfort, he uses pretreatment acetaminophen if patients can take it. After a skin reaction occurs, cool compresses are used, along with dilute acetic acid soaks on crusted or scaling lesions in an effort to prevent infection.

And while these treatments can produce quite angry-looking lesions in the short term, very good healing usually occurs if patients are diligent about wound care. However, Dr. Rossi cautioned that they may need “more hand holding with these nonsurgical treatments, because it is a longer duration of treatment.”

In general for counseling patients on nonsurgical treatments, Dr. Rossi said it is advisable to have good pretreatment and post-treatment plans. “They have to know that they will need to be following up to make sure that there is no recurrence,” he said. “We don’t have clear surgical margins if we’re using these topical treatments, so we have to make sure that they have good, constant follow-up.”

Dr. Rossi reported consulting relationships with Merz, DynaMed, and Novartis.

BOSTON – Aluminum chloride, a chemical found in rocks and as ancient as the earth itself, still can control hyperhidrosis for many people when used correctly. It is the active ingredient in over-the-counter antiperspirants as well as prescription products.

At the American Academy of Dermatology summer meeting, Louis Kuchnir, MD, who is a physical chemist by training as well as a dermatologist, described the chemical properties of aluminum chloride and how it works, based on those properties.

Just as no dermatologist would prescribe isotretinoin for acne without understanding its mechanism of action, so should physicians know how aluminum chloride works to be able to use it effectively, he said. Each aluminum chloride molecule can covalently bind six water molecules and tightly bind another shell or two of 12-20 molecules, with a further third shell, all “making the water very viscous such that the weak muscles that push sweat out of our sweat glands are unable to move the sweat to the surface of our skin,” he said.

“When aluminum chloride gets close to water, it soaks it up and thickens it,” said Dr. Kuchnir, who is in private practice in Marlborough, Mass. “By spreading it over the areas that perspire, it thickens the water in the top of the duct where the sweat’s coming out, and that thickening, like a gel, will block it.” Most people get satisfactory results for a full day from one application of an antiperspirant containing aluminum chloride. A failure to control sweating results from such excessive sweat gland activity that the moisture pushes the gel away from the top of the sweat gland.

Diagnosis of hyperhidrosis

A diagnosis of primary hyperhidrosis requires focal, visible sweating present for at least 6 months with no apparent secondary causes and at least two of the following criteria:

• It is bilateral and symmetric.

• It impairs activities of daily life.

• There is at least one episode per week.

• The age of onset is less than 25 years.

• There is a positive family history.

• There is cessation during sleep.

Patients whose sweating is not controlled with regular antiperspirant deodorants may find relief using an aluminum chloride–containing liquid that is not a classic deodorant. These products are available over the counter. Beyond that, primary care doctors often prescribe a 20% aluminum chloride liquid, which can be very effective.

If a patient still has hyperhidrosis, often of the axillae or the palms of the hand, a dermatologist may recommend injections of botulinum toxin A “to disable sweat glands up to 10 months at a time ... which is a costly procedure that has been heavily marketed over the past 5-10 years,” Dr. Kuchnir said. By asking patients what they have been using and what the problem is, and understanding why aluminum chloride failed them in the past, he has found that he could get “four out of five of these patients to be happy and not perspiring with topical antiperspirants, often prescription strength, even though virtually all of them are ready to go for neurotoxins when I first meet them.” The remaining 20% will need botulinum toxin A to block nerve endings from communicating with the smooth muscle in the eccrine gland, which is required to push sweat out of the gland.

Botulinum toxin for hyperhidrosis is covered by prescription drug benefit plans, and prior authorization is routine. Patients should obtain the drug at the best price they can find and then bring it to the physician for injection. The duration of action is often 8-10 months, so dosing can be done yearly in the springtime. Aluminum chloride preparations can be retried once botulinum toxin wears off.

Countering common problems with aluminum chloride preparations

The two most common complaints about topical aluminum chloride preparations are that they sting or do not work. Stinging is often from alcohol in the liquids, so letting it evaporate from the armpits before patients put their arms down can solve this problem. As for the problem of not controlling sweating, Dr. Kuchnir said the most common reason is that patients apply the products while they are actively sweating, “so the aluminum chloride doesn’t have time to gel in the eccrine gland.” Another reason is that the preparation has too much moisture in it and will fail to block sweating.

To be able to apply an antiperspirant to dry skin, patients should minimize the causes of sweating by being in a cool, calm environment. The temporary use of anticholinergic drugs may help. Once control of sweating is achieved, the aluminum chloride–containing preparation should be reapplied before it wears off.

Dr. Kuchnir says he encourages dermatologists to bring the same level of care, understanding, and communication to patients suffering from hyperhidrosis that they do to patients whom they see for acne. Just as clinicians do not always use the strongest medicines but choose the safest ones, especially ones that can be self-administered and self-guided, teaching patients how to use antiperspirants when they will work “is as important as being able to effectively and safely inject neurotoxins,” Dr. Kuchnir advised.

While many patients have heard reports of an association between the use of aluminum chloride–containing antiperspirants and a risk of breast cancer or of aluminum in general being associated with Alzheimer’s disease, he says he tells his patients that “aluminum chloride is completely safe, and I don’t say that about a lot of prescription medicines.”

Dr. Kuchnir reported having no financial disclosures.

If a patient still has hyperhidrosis, often of the axillae or the palms of the hand, a dermatologist may recommend injections of botulinum toxin A “to disable sweat glands up to 10 months at a time ... which is a costly procedure that has been heavily marketed over the past 5-10 years,” Dr. Kuchnir said. By asking patients what they have been using and what the problem is, and understanding why aluminum chloride failed them in the past, he has found that he could get “four out of five of these patients to be happy and not perspiring with topical antiperspirants, often prescription strength, even though virtually all of them are ready to go for neurotoxins when I first meet them.” The remaining 20% will need botulinum toxin A to block nerve endings from communicating with the smooth muscle in the eccrine gland, which is required to push sweat out of the gland.

Botulinum toxin for hyperhidrosis is covered by prescription drug benefit plans, and prior authorization is routine. Patients should obtain the drug at the best price they can find and then bring it to the physician for injection. The duration of action is often 8-10 months, so dosing can be done yearly in the springtime. Aluminum chloride preparations can be retried once botulinum toxin wears off.

Countering common problems with aluminum chloride preparations

The two most common complaints about topical aluminum chloride preparations are that they sting or do not work. Stinging is often from alcohol in the liquids, so letting it evaporate from the armpits before patients put their arms down can solve this problem. As for the problem of not controlling sweating, Dr. Kuchnir said the most common reason is that patients apply the products while they are actively sweating, “so the aluminum chloride doesn’t have time to gel in the eccrine gland.” Another reason is that the preparation has too much moisture in it and will fail to block sweating.

To be able to apply an antiperspirant to dry skin, patients should minimize the causes of sweating by being in a cool, calm environment. The temporary use of anticholinergic drugs may help. Once control of sweating is achieved, the aluminum chloride–containing preparation should be reapplied before it wears off.

Dr. Kuchnir says he encourages dermatologists to bring the same level of care, understanding, and communication to patients suffering from hyperhidrosis that they do to patients whom they see for acne. Just as clinicians do not always use the strongest medicines but choose the safest ones, especially ones that can be self-administered and self-guided, teaching patients how to use antiperspirants when they will work “is as important as being able to effectively and safely inject neurotoxins,” Dr. Kuchnir advised.

While many patients have heard reports of an association between the use of aluminum chloride–containing antiperspirants and a risk of breast cancer or of aluminum in general being associated with Alzheimer’s disease, he says he tells his patients that “aluminum chloride is completely safe, and I don’t say that about a lot of prescription medicines.”

Dr. Kuchnir reported having no financial disclosures.

BOSTON – Aluminum chloride, a chemical found in rocks and as ancient as the earth itself, still can control hyperhidrosis for many people when used correctly. It is the active ingredient in over-the-counter antiperspirants as well as prescription products.

At the American Academy of Dermatology summer meeting, Louis Kuchnir, MD, who is a physical chemist by training as well as a dermatologist, described the chemical properties of aluminum chloride and how it works, based on those properties.

Just as no dermatologist would prescribe isotretinoin for acne without understanding its mechanism of action, so should physicians know how aluminum chloride works to be able to use it effectively, he said. Each aluminum chloride molecule can covalently bind six water molecules and tightly bind another shell or two of 12-20 molecules, with a further third shell, all “making the water very viscous such that the weak muscles that push sweat out of our sweat glands are unable to move the sweat to the surface of our skin,” he said.

“When aluminum chloride gets close to water, it soaks it up and thickens it,” said Dr. Kuchnir, who is in private practice in Marlborough, Mass. “By spreading it over the areas that perspire, it thickens the water in the top of the duct where the sweat’s coming out, and that thickening, like a gel, will block it.” Most people get satisfactory results for a full day from one application of an antiperspirant containing aluminum chloride. A failure to control sweating results from such excessive sweat gland activity that the moisture pushes the gel away from the top of the sweat gland.

Diagnosis of hyperhidrosis

A diagnosis of primary hyperhidrosis requires focal, visible sweating present for at least 6 months with no apparent secondary causes and at least two of the following criteria:

• It is bilateral and symmetric.

• It impairs activities of daily life.

• There is at least one episode per week.

• The age of onset is less than 25 years.

• There is a positive family history.

• There is cessation during sleep.

CHICAGO – Combining an immunostimulatory agent with the PD-1 checkpoint inhibitor pembrolizumab appeared quite safe and very tolerable, in a small phase Ib study.

There were some signs of efficacy against a variety of solid tumors, as well as biomarker trends showing immune activity.

In the phase Ib trial, researchers combined escalating doses (0.45-5.0 mg/kg) of PF-2566, an investigative immunostimulatory agent, with the anti–PD-1 checkpoint inhibitor pembrolizumab at 2 mg/kg, with both drugs given intravenously once every 3 weeks for a maximum of 32 cycles. A primary objective of the trial was to determine a maximum tolerated dose. Secondary objectives were to assess safety and tolerability and to determine any antitumor responses.

PF-2566 (Utomilumab/PF-05082566) is a monoclonal agonist targeting 4-1BB, a “costimulatory molecule that’s induced upon T-cell receptor activation and ultimately enhances cytotoxic T-cell response and effector status,” said Dr. Anthony Tolcher of the START Center for Cancer Care, San Antonio, at the annual meeting of the American Society of Clinical Oncology.

Eligible patients were 18 years or older, had a performance status of 0-1, and had advanced or metastatic solid tumors that had progressed on standard therapy or for which no standard therapy was available. They could not have had any form of immunosuppressive therapy in the 2 weeks prior to registration, a monoclonal antibody in the 2 months before the first dose, or any symptomatic or progressing central nervous system primary malignancies. Prior pembrolizumab was permitted.

Twenty-three patients (14 males) were heavily pretreated with a median of three prior therapies (range 0-9) for a variety of cancers, including six non–small-cell lung, five renal cell, three head and neck, and two each pancreatic and thyroid cancers.

Good safety and tolerability profiles

The most prevalent treatment-emergent adverse events (AEs) were fatigue, rash, cough, nausea, and decreased appetite, affecting 7-10 patients each. All were grade 1/2 except for one grade 3/4 case of fatigue and three cases of grade 3/4 anemia among the 23 patients. Most treatment-related AE’s were grade 1/2, largely fatigue (n = 8) and rash (n = 9). There was one case each of grade 3 adrenal insufficiency and hypokalemia. No patient discontinued the trial because of a treatment-related toxicity. Dr. Tolcher noted that adrenal insufficiency has been reported previously with the use of PD-1 inhibitors. “There does not appear to be any evidence of synergistic or additive toxicity in this patient population,” he said.

Neither drug affected the pharmacokinetics of the other drug or the development of antibodies to the other drug. The maximum tolerated dose of PF-2566 was at least 5 mg/kg every 3 weeks when combined with pembrolizumab 2 mg/kg. No dose-limiting toxicity was observed across the PF-2566 dosing range. And there were no treatment-emergent AEs of clinical relevance.

Pharmacodynamics and efficacy

By day 1 of cycle 5, “there [was] a trend toward increasing numbers of activated CD8 [cytotoxic] T cells in patients who ultimately responded or had a complete response, compared to those that had stable disease or progressive disease. The same actually applies to the effector memory T cells,” Dr. Tolcher said but was careful to point out that the sample sizes were small and it was only a trend. Similarly, circulating levels of gamma-interferon, often used as a biomarker of activated T cells, were higher at 6 and 24 hours post dose in cycle 5 for those patients who ultimately had partial or complete responses, compared with those with progressive or stable disease.

Among the 23 patients, there were two confirmed complete responses and four partial responses as well as one unconfirmed partial response. If responses occurred, they often were durable past 1 year and even out close to 2 years.

The strengths of this study were that it enrolled heavily pretreated patients and there were no drug-drug interactions, no dose-limiting toxicities, and no treatment-related AE’s leading to discontinuation, “so in general a very well-tolerated immunotherapy combination,” said discussant Dr. David Spigel of the Sarah Cannon Research Institute in Nashville, Tenn. There were also some durable responses, and he said it was interesting to see that there were some blood biomarkers that correlated with responses.

“It was hard for me to find any weaknesses to this,” Dr. Spigel said, beside the fact that it was a small study. “So what does this change?” He said the combination of pembrolizumab and PF-2566 looks promising in light of some sustained responses in refractory tumors and its safety profile. For the future, expansion trial cohorts are still needed to confirm activity and safety, especially hepatic safety based on trial results with similar drugs, and PF-2566 is already being tested with rituximab in lymphoma and with an anti-CCR4 compound (mogamulizumab).

The study was sponsored by Pfizer and Merck. Dr. Tolcher has ties to several companies, including Pfizer and Merck. Dr. Spigel has ties to several companies, including Pfizer.

CHICAGO – Combining two immunotherapies, one inhibiting immune suppression and the other stimulating immune activation, is well tolerated and shows activity for a variety of solid tumor types, according to a phase I trial presented at the annual meeting of the American Association of Clinical Oncology.

Investigators enrolled 51 patients with locally advanced or metastatic solid tumors of any type after progression on standard therapy to a phase Ib dose-escalation study using atezolizumab, a monoclonal antibody checkpoint inhibitor that targets PD-L1, in combination with MOXR0916 (MOXR), an agonist IgG1 monoclonal antibody targeting OX40, a costimulatory receptor. Atezolizumab received Food and Drug Administration approval in May 2016 for use in certain patients with urothelial carcinoma. There were 28 patients in a dose-escalation cohort of the study and 23 in a serial biopsy cohort. The dose of the drug combination was started at 12 mg and escalated to understand pharmacodynamic changes in the tumors.

“The pharmacokinetics of both MOXR0916 and atezolizumab were similar to their single-agent data, suggesting no interaction,” reported Dr. Jeffrey Infante of the Sarah Cannon Research Institute in Nashville, Tenn.

The drug combination was well tolerated through the entire escalation range of MOXR. There were no dose-limiting toxicities, and no maximal tolerated dose was reached. There were also no drug-related deaths or grade 4 toxicities or drug-related treatment discontinuations. One case of grade 3 pneumonitis, successfully managed with methylprednisolone and antibiotics, occurred at the MOXR 40-mg dose on cycle 4 of treatment in a patient with non–small-cell lung cancer, he said.

About half the patients (53%) experienced any form of adverse event on the drug combination, and only 8% were grade 2 or 3. There were very few adverse events of any one type, and they did not appear to cluster among patients on the higher MOXR doses. The most prevalent adverse events were nausea, fever, fatigue, and rash, and each was in the 8%-14% range and almost always grade 1.

Many patients showed efficacy of the regimens out to 6-7 cycles regardless of tumor type, and 8 of the 51 patients were still receiving the therapy past cycle 7 with partial responses.

The stimulatory molecule OX40 is not normally expressed on T cells, but it is expressed when antigen interacts with the T-cell receptor, and it can then interact with its ligand, OX40L. The result is production of inflammatory cytokines such as gamma-interferon, activation and survival of effector T cells, and production of memory T cells. At the same time, OX40 activity blocks the suppressive function of regulatory T cells.

“So a molecule that can be a cancer therapeutic such as an OX40 agonist has dual mechanisms of action,” Dr. Infante said. “It can costimulate effector T cells and at the same time inhibit regulatory T cells. Furthermore, there is a reduced risk of toxicity, potentially, as its activity is linked to antigen recognition.”

There is good rationale for using an OX40 agonist such as MOXR, either for its immune stimulatory function or to deactivate immune suppression by regulatory T cells, or both, said discussant Dr. Jedd Wolchok, chief, melanoma and immunotherapeutics service, Memorial Sloan-Kettering Cancer Center, New York. Dr. Infante’s dose-escalation study was “very nicely designed and showed quite good safety,” Dr. Wolchok said, though one thing he would have liked to have seen was a quantification of regulatory T cells in tumor biopsies.

“This [study] is very important considering that this is an agonist antibody, and the agonist agents need to be dosed very deliberatively, as was done here, to ensure safety of patients,” Dr. Wolchok said, adding that further research needs to target “optimal combinatorial partners” and explore other mechanistic biomarkers.

MOXR was given in this trial at escalating doses on a 3+3 design (0.8-1,200 mg) on the same day as atezolizumab 1,200 mg IV once every 3 weeks with a 21-day window for assessment of MOXR dose-limiting toxicities. MOXR doses of 300 mg maintained trough concentrations sufficient to saturate OX40 receptors. An expansion regimen using 300 mg MOXR with atezolizumab 1,200 mg every 3 weeks is underway and will assess efficacy in the treatment of melanoma, renal cell carcinoma, non–small-cell lung cancer, urothelial carcinoma, and triple-negative breast cancer.

The study was sponsored by Roche. Dr. Infante reported having no relevant financial disclosures. Dr. Wolchok owns stock in Potenza Therapeutics and Vesuvius Pharmaceuticals, has received travel expenses and/or has an advisory role with several other companies, and is a coinventor on an issued patent for DNA vaccines for the treatment of cancer in companion animals.

The most prevalent adverse events were nausea, fever, fatigue, and rash, and each was in the 8%-14% range and almost always grade 1.

Many patients showed efficacy of the regimens out to 6-7 cycles regardless of tumor type, and 8 of the 51 patients were still receiving the therapy past cycle 7 with partial responses.

The stimulatory molecule OX40 is not normally expressed on T cells, but it is expressed when antigen interacts with the T-cell receptor, and it can then interact with its ligand, OX40L. The result is production of inflammatory cytokines such as gamma-interferon, activation and survival of effector T cells, and production of memory T cells. At the same time, OX40 activity blocks the suppressive function of regulatory T cells.

“So a molecule that can be a cancer therapeutic such as an OX40 agonist has dual mechanisms of action,” Dr. Infante said. “It can costimulate effector T cells and at the same time inhibit regulatory T cells. Furthermore, there is a reduced risk of toxicity, potentially, as its activity is linked to antigen recognition.”

There is good rationale for using an OX40 agonist such as MOXR, either for its immune stimulatory function or to deactivate immune suppression by regulatory T cells, or both, said discussant Dr. Jedd Wolchok, chief, melanoma and immunotherapeutics service, Memorial Sloan-Kettering Cancer Center, New York. Dr. Infante’s dose-escalation study was “very nicely designed and showed quite good safety,” Dr. Wolchok said, though one thing he would have liked to have seen was a quantification of regulatory T cells in tumor biopsies.

“This [study] is very important considering that this is an agonist antibody, and the agonist agents need to be dosed very deliberatively, as was done here, to ensure safety of patients,” Dr. Wolchok said, adding that further research needs to target “optimal combinatorial partners” and explore other mechanistic biomarkers.

MOXR was given in this trial at escalating doses on a 3+3 design (0.8-1,200 mg) on the same day as atezolizumab 1,200 mg IV once every 3 weeks with a 21-day window for assessment of MOXR dose-limiting toxicities. MOXR doses of 300 mg maintained trough concentrations sufficient to saturate OX40 receptors. An expansion regimen using 300 mg MOXR with atezolizumab 1,200 mg every 3 weeks is underway and will assess efficacy in the treatment of melanoma, renal cell carcinoma, non–small-cell lung cancer, urothelial carcinoma, and triple-negative breast cancer.

The study was sponsored by Roche. Dr. Infante reported having no relevant financial disclosures. Dr. Wolchok owns stock in Potenza Therapeutics and Vesuvius Pharmaceuticals, has received travel expenses and/or has an advisory role with several other companies, and is a coinventor on an issued patent for DNA vaccines for the treatment of cancer in companion animals.

ORLANDO – In the case of transgender youth and adults – those with what is now called gender dysphoria – physicians are faced with treating individuals who generally have no physical disease or abnormalities.

Endocrinologists are the professionals who are often tasked with the medical aspects of treating gender dysphoria. In an effort to help them understand the underpinnings and aspects of the conditions, Dr. Stephen Rosenthal, professor of pediatrics and medical director of the Child and Adolescent Medical Gender Center at the University of California, San Francisco, reviewed current knowledge about the biological basis for gender identity, current treatment models, and barriers to care of patients with gender dysphoria.

Speaking at the annual meeting of the American Association of Clinical Endocrinologists, Dr. Rosenthal said the dysphoria derives from the significant emotional distress that may be associated with a transgender identity, essentially from the social and psychological pressures of being born and living in a body (the “natal sex”) that does not match an individual’s gender identity, defined as one’s fundamental sense of self as male or female. “It’s not always limited to those two choices, and it’s not always binary,” he said, since individuals may identify with aspects of both or, at times, neither gender.

He defined some terms, such as transgender, which refers to a transient or persistent identification with gender different from the one others assume based on physical sex characteristics at birth. That gender becomes the one of rearing, which may not be how the individual feels growing up. Gender identity should not be confused with sexual identity or orientation because people of any gender can have any sexual orientation.

“Gender Identity Disorder,” a term used in the DSM IV (Diagnostic and Statistical Manual of Mental Disorders IV) has been replaced by “Gender Dysphoria in Children” in DSM 5. And even that term may be revised since transgender identity in itself is not a pathology.

In one survey of 28,176 people, 0.5% self-identified as transgender. Another survey showed statistically significant risks associated with being transgender. Comparing 180 transgender youth with 180 non–transgender youth (average age, 19.6 years; range, 12-29 years), researchers found a two- to threefold increased risk of depression, anxiety disorder, suicidal ideation, suicide attempt, and self- harm without lethal intent among the transgender youths. Parental support helped alleviate some of these risks, especially suicide attempts, but did not eliminate them entirely; that support also contributed to better mental and physical health, improved self-esteem, and even adequate food and housing for transgender adolescents.

Clues to biological influences

A complex interplay of biological, environmental, and cultural factors affect the determination of gender identity. Evidence points to the role of biology in gender identity development through studies of genetics, hormones, and the brain, but none of these is a “litmus test” for gender identity, Dr. Rosenthal said.

A study of 23 monozygotic twin pairs, 21 same-sex dizygotic twin pairs, and 7 opposite-sex twin pairs showed a 39.1% concordance for gender dysphoria among the monozygotic twins but none for the other sets.

Most transgender individuals do not have any obvious disorder of sexual development, but that is not to rule out a role of prenatal or postnatal androgens (specifically enzymes of the steroid pathways), androgen insensitivity, or extragonadal sources of androgen, as in congenital adrenal hyperplasia (CAH). Among 250 46XX females with CAH raised as female, 5.2% had male gender identity or gender dysphoria (a 10- to 20-fold increased risk vs. controls), suggesting a possible role for prenatal androgens in gender identity development.

A neurobiological basis for transgender is supported by some studies of sexually dimorphic brain structures but is by no means conclusive. Numerous studies of gray and white matter showed that sexually dimorphic structures are more closely aligned with gender identity than with physical sex (even before cross-sex hormones have been applied). But morphometry on areas of the brain that show the largest sex differences found that variability was more prevalent than was consistency in the 1,400 brains studied.

Tests of “functional sexual dimorphism” used PET or MRI to measure changes in regional blood flow in the anterior hypothalamus when control adolescent girls or boys or those with gender dysphoria were asked to smell substances containing pheromones of the opposite sex (for girls: androstadienone in a mixture of male sweat and semen; for boys: estrogen-like compounds in urine of pregnant women). Both girls and boys with gender dysphoria had responses significantly different from those of their respective controls.

Natural history of gender dysphoria

Dr. Rosenthal said symptoms of gender dysphoria in prepubertal children decrease or disappear in 70%-95% of cases, but if they persist into early puberty, the individual is likely to be transgender as an adult. Children with more intense gender dysphoria and those who believed they “were” the opposite sex were more likely to have persistent gender dysphoria as adults. In a study based on parents’ completed measures, prepubescent transgender boys and girls who have socially transitioned had depression scores no higher than those of matched nontransgender controls. They had much lower anxiety and depression, compared with non–socially transitioned transgender historical control children.

Medically induced sexual transitioning

For pediatric and adolescent transsexual patients who express a desire to transition to the opposite sex, an Endocrine Society clinical practice guideline on endocrine treatment recommends that a mental health professional make the diagnosis of gender dysphoria. Then the medical provider needs to ensure that the patient understands the consequences of hormone suppression and cross-sex hormone therapy prior to beginning treatments. Only after early puberty has begun should gonadotropin-releasing hormone (GnRH) agonists be used to suppress pubertal hormones. At about age 16 years, cross-sex hormone treatments can begin, with surgery deferred at least until age 18 years if the patient desires full transitioning.

A Dutch study (Pediatrics. 2014 Oct. 134:696-704) showed that after gender reassignment, in young adulthood, gender dysphoria “was alleviated and psychological functioning had steadily improved. Well-being was similar to or better than same-age young adults from the general population.” No patients reported any regret during any stages of the sex-reassignment protocol.

There is some concern about adverse effects of the GnRH agonists, such as on bone mass and health, the brain, and fertility. But no detrimental effects were observed in a study on executive functioning, which undergoes significant development during puberty, in either male-to-female or female-to-male individuals.

Future parenthood may be an option if the patient is old enough. “We always encourage them to either freeze sperm, or we can potentially freeze eggs before embarking on phenotypic transition,” Dr. Rosenthal said. But allowing a patient to get to a stage of spermatogenesis or egg production would allow puberty to proceed to a significant degree. “So one of the exciting areas of research is actually taking prepubertal tissue … [in mice] they took neonatal testicular tissue and they basically showed you could take it all the way through the steps of full maturation and get progeny that were reproductively competent,” he said. Similar studies are being done in humans, mainly because there is interest in preserving fertility of children undergoing cancer treatments.

Barriers to care for transgender youth include limited access to medications, including off-label use, great expense, and insurance company denials of reimbursement. There are also relatively few clinical programs and a lack of training for health care professionals, as well as prejudice and misunderstanding, even among professionals.

Chicago – Survivors of childhood cancers face several later risks from treatment, and investigators presented studies evaluating risks in three specific areas – secondary neoplasms, premature menopause, and neurocognitive function – at the annual meeting of the American Society of Clinical Oncology.

Discussant Paul Nathan, M.D., of The Hospital for Sick Children in Toronto, said “the whole purpose” of research in this area “is to start to understand the predictors and modifiers of late effects” and then to design risk assessment tools and interventions to reduce long-term toxicity. These interventions include modification of chemotherapy and radiation doses, protective strategies, and disease risk stratification to adjust intensity of therapies.

Other strategies are to use behavioral interventions directed at improving compliance with follow-up to detect problems earlier and the use of real-time monitoring, such as with smart phones or fitness trackers. He said one limitation of this sort of research and implementing interventions to reduce late toxicities is that “you need time to document long-term outcomes.” So tracking newer therapies, such as proton beam radiation, small molecule drugs, and immunotherapy, is “going to take time, perhaps decades, before you understand their impact on patients.”

Risk of secondary neoplasms reduced

Risk-stratifying of disease “has allowed us to make attempts to minimize late effects by modifying therapy over time in certain subgroups of lower-risk patients,” said Dr. Lucie Turcotte of the University of Minnesota in Minneapolis.

To study the effects of these changes, she determined the risk of certain subsequent malignant or benign neoplasms over three periods of therapeutic exposure among 23,603 5-year survivors of childhood cancers diagnosed at less than 21 years of age from 1970 to 1999, drawing from the cohort of the Childhood Cancer Survivor Study (CCSS). The CCSS represents about 20% of childhood cancer survivors in the United States for the study period.

Over the decades of 1970-1979, 1980-1989, and 1990-1999, the use of any radiation went from 77% to 58% to 41%, respectively. Cranial radiation for acute lymphoblastic leukemia (ALL) decreased from 85% to 19%, abdominal radiation for Wilms tumor from 78% to 43%, and chest radiotherapy for Hodgkin lymphoma from 87% to 61%. The proportion of children receiving alkylating agents, anthracyclines, and epipodophyllotoxins went up, but the cumulative doses went down (N Engl J Med. 2016 Mar 3;374(9):833-42).

Dr. Nathan said today, almost no child gets cranial radiation for ALL. “So we’ve slowly learned that our treatments are toxic, and we’ve certainly done what we can to change them.”

But have these changes made a difference? Dr. Turcotte found that survivors remain at increased risk of a secondary neoplasm, but the risk was lower for children treated in later time periods.

Dr. Nathan pointed to Dr. Turcotte’s data showing that the incidence of subsequent malignant neoplasms decreased from 1970 to 1999 by 7% for each 5-year era (15-year risk: 2.3% to 1.6%; P = .001; number needed to treat, NNT = 143). Similarly, non-melanoma skin cancer 15-year risk decreased from 0.7% to 0.1% (P less than .001; NNT = 167). The NNT’s are “certainly important, but these are not major differences over time,” Dr. Nathan said. Knowing the impact of newer, targeted therapeutic approaches will take some time.

Predicting risk of premature menopause

Also using the CCSS data, Dr. Jennifer Levine of Columbia University Medical Center, New York, N.Y., studied the prevalence of and risk factors for nonsurgical premature menopause (NSPM), defined as cessation of menses prior to age 40 years, as well as the effect on reproductive outcomes for survivors of childhood cancers.

Dr. Nathan said when a child is first diagnosed with cancer, seldom does the issue of fertility come up early in the discussion, “but when you treat young adults who are survivors, the number one thing they talk about often is fertility. And so doing a better job in predicting who is at risk for infertility is clearly a priority for survivorship research.”

He said the development of the cyclophosphamide equivalent dose (CED) by D.M Green et al. (Pediatr Blood Cancer. 2014 Jan;61(1):53-67) has been very helpful for quantifying alkylating agent exposure to make comparisons between studies. The goal is to develop a risk assessment tool to be able to tell patients and families their fertility risk based on demographics, therapy, and biomarkers.

Being able to evaluate risk is critically important because for girls, oocyte or ovarian harvesting or even transvaginal ultrasound is highly invasive, and these procedures should be recommended only if their risk for infertility is very high.

Dr. Levine studied 2,930 female cancer survivors diagnosed at a median age of 6 years between 1979 and 1986 and a median age at follow-up of 34 years, who were compared with 1,399 healthy siblings. Of the survivor cohort, 110 developed NSPM at a median age of 32 years, and the prevalence of NSPM at age 40 years for the entire cohort was 9.1%, giving a relative risk of NSPM of 10.5 compared with siblings, who had a 0.9% NSPM prevalence at age 40.

She found that exposure to alkylating agents and older age at diagnosis put childhood cancer survivors at increased risk of NSPM, which was associated with lower rates of pregnancy and live births after age 31 years. The greatest risk of NSPM occurred if the cyclophosphamide equivalent dose was greater than 6000 mg/m² (odds ratio = 3.6 compared with no CED); if there had been any radiation to the ovaries (less than 5 Gy: OR = 4.0; 5 Gy or more: OR = 20.4); or if the age at diagnosis was greater than 14 years (OR = 2.3).

Women with NSPM, compared with survivors without NSPM, were less likely ever to be pregnant (OR = 0.41) or to have a live birth after age 30 (OR = 0.35). However, these outcomes were no different between the ages of 21 and 30. Dr. Levine said this information can assist clinicians in counseling their patients about the risk for early menopause and planning for alternative reproductive means, such as oocyte or embryo harvesting and preservation.

Neurocognitive functioning after treatment

Dr. Wei Liu of St. Jude Children’s Research Hospital, Memphis, Tenn., studied the neurocognitive function of long-term survivors of ALL.

Dr. Nathan called ALL “the paradigm for how we’ve sort of learned and adjusted how we treat patients based on late effects.” Early on, the disease was treated with craniospinal radiation and intrathecal chemotherapy, and while patients survived, it became obvious that they suffered neurocognitive and endocrine problems, growth abnormalities, and secondary malignancies. These findings forced a reevaluatuon of treatments, leading to elimination of spinal radiation, reduction of cranial radiation dose, intensification of systemic therapy, including methotrexate, and risk stratification allowing modification of therapies.

Survival was sustained, but long-term outcomes were still based on children treated with radiation. So long-term cognitive consequences in the more modern era of therapy were unknown. Only recently have adult cohorts become available who were treated in the chemotherapy-only era.

Dr. Liu studied 159 ALL survivors who had been treated with chemotherapy alone at a mean age of 9.2 years. The follow-up was at a median of 7.6 years off therapy at a mean age of 13.7 years. At the end of the chemotherapy protocol, patients completed tests of sustained attention, and parents rated survivors’ behavior on standard scales.

She found that for these childhood cancer survivors, sustained attention and behavior functioning at the end of chemotherapy predicted long-term attention and processing speed outcomes. Only exposure to chemotherapy, and not end-of-therapy function, predicted that survivors would have poor executive function of fluency and flexibility at long-term follow up.

Dr. Nathan praised the investigators for their foresight to collect data on the methotrexate area under the curve, number of triple intrathecal therapies (cytarabine, methotrexate, and hydrocortisone), and neurocognitive functioning at the end of chemotherapy. “What’s clear is that chemotherapy alone can lead to neurocognitive late effects,” he said. “But what’s also important is that not all late effects can be predicted by end of therapy assessments.” These late effects appear to evolve over time, so ongoing assessments are needed.

Dr. Turcotte, Dr. Liu, Dr. Levine, and Dr. Nathan each reported no financial disclosures.

Over the decades of 1970-1979, 1980-1989, and 1990-1999, the use of any radiation went from 77% to 58% to 41%, respectively. Cranial radiation for acute lymphoblastic leukemia (ALL) decreased from 85% to 19%, abdominal radiation for Wilms tumor from 78% to 43%, and chest radiotherapy for Hodgkin lymphoma from 87% to 61%. The proportion of children receiving alkylating agents, anthracyclines, and epipodophyllotoxins went up, but the cumulative doses went down (N Engl J Med. 2016 Mar 3;374(9):833-42).

Dr. Nathan said today, almost no child gets cranial radiation for ALL. “So we’ve slowly learned that our treatments are toxic, and we’ve certainly done what we can to change them.”

But have these changes made a difference? Dr. Turcotte found that survivors remain at increased risk of a secondary neoplasm, but the risk was lower for children treated in later time periods.

Dr. Nathan pointed to Dr. Turcotte’s data showing that the incidence of subsequent malignant neoplasms decreased from 1970 to 1999 by 7% for each 5-year era (15-year risk: 2.3% to 1.6%; P = .001; number needed to treat, NNT = 143). Similarly, non-melanoma skin cancer 15-year risk decreased from 0.7% to 0.1% (P less than .001; NNT = 167). The NNT’s are “certainly important, but these are not major differences over time,” Dr. Nathan said. Knowing the impact of newer, targeted therapeutic approaches will take some time.

Predicting risk of premature menopause

Also using the CCSS data, Dr. Jennifer Levine of Columbia University Medical Center, New York, N.Y., studied the prevalence of and risk factors for nonsurgical premature menopause (NSPM), defined as cessation of menses prior to age 40 years, as well as the effect on reproductive outcomes for survivors of childhood cancers.

Dr. Nathan said when a child is first diagnosed with cancer, seldom does the issue of fertility come up early in the discussion, “but when you treat young adults who are survivors, the number one thing they talk about often is fertility. And so doing a better job in predicting who is at risk for infertility is clearly a priority for survivorship research.”

He said the development of the cyclophosphamide equivalent dose (CED) by D.M Green et al. (Pediatr Blood Cancer. 2014 Jan;61(1):53-67) has been very helpful for quantifying alkylating agent exposure to make comparisons between studies. The goal is to develop a risk assessment tool to be able to tell patients and families their fertility risk based on demographics, therapy, and biomarkers.

Being able to evaluate risk is critically important because for girls, oocyte or ovarian harvesting or even transvaginal ultrasound is highly invasive, and these procedures should be recommended only if their risk for infertility is very high.

Dr. Levine studied 2,930 female cancer survivors diagnosed at a median age of 6 years between 1979 and 1986 and a median age at follow-up of 34 years, who were compared with 1,399 healthy siblings. Of the survivor cohort, 110 developed NSPM at a median age of 32 years, and the prevalence of NSPM at age 40 years for the entire cohort was 9.1%, giving a relative risk of NSPM of 10.5 compared with siblings, who had a 0.9% NSPM prevalence at age 40.

She found that exposure to alkylating agents and older age at diagnosis put childhood cancer survivors at increased risk of NSPM, which was associated with lower rates of pregnancy and live births after age 31 years. The greatest risk of NSPM occurred if the cyclophosphamide equivalent dose was greater than 6000 mg/m² (odds ratio = 3.6 compared with no CED); if there had been any radiation to the ovaries (less than 5 Gy: OR = 4.0; 5 Gy or more: OR = 20.4); or if the age at diagnosis was greater than 14 years (OR = 2.3).

Women with NSPM, compared with survivors without NSPM, were less likely ever to be pregnant (OR = 0.41) or to have a live birth after age 30 (OR = 0.35). However, these outcomes were no different between the ages of 21 and 30. Dr. Levine said this information can assist clinicians in counseling their patients about the risk for early menopause and planning for alternative reproductive means, such as oocyte or embryo harvesting and preservation.

Neurocognitive functioning after treatment

Dr. Wei Liu of St. Jude Children’s Research Hospital, Memphis, Tenn., studied the neurocognitive function of long-term survivors of ALL.

Dr. Nathan called ALL “the paradigm for how we’ve sort of learned and adjusted how we treat patients based on late effects.” Early on, the disease was treated with craniospinal radiation and intrathecal chemotherapy, and while patients survived, it became obvious that they suffered neurocognitive and endocrine problems, growth abnormalities, and secondary malignancies. These findings forced a reevaluatuon of treatments, leading to elimination of spinal radiation, reduction of cranial radiation dose, intensification of systemic therapy, including methotrexate, and risk stratification allowing modification of therapies.

Survival was sustained, but long-term outcomes were still based on children treated with radiation. So long-term cognitive consequences in the more modern era of therapy were unknown. Only recently have adult cohorts become available who were treated in the chemotherapy-only era.

Dr. Liu studied 159 ALL survivors who had been treated with chemotherapy alone at a mean age of 9.2 years. The follow-up was at a median of 7.6 years off therapy at a mean age of 13.7 years. At the end of the chemotherapy protocol, patients completed tests of sustained attention, and parents rated survivors’ behavior on standard scales.

She found that for these childhood cancer survivors, sustained attention and behavior functioning at the end of chemotherapy predicted long-term attention and processing speed outcomes. Only exposure to chemotherapy, and not end-of-therapy function, predicted that survivors would have poor executive function of fluency and flexibility at long-term follow up.

Dr. Nathan praised the investigators for their foresight to collect data on the methotrexate area under the curve, number of triple intrathecal therapies (cytarabine, methotrexate, and hydrocortisone), and neurocognitive functioning at the end of chemotherapy. “What’s clear is that chemotherapy alone can lead to neurocognitive late effects,” he said. “But what’s also important is that not all late effects can be predicted by end of therapy assessments.” These late effects appear to evolve over time, so ongoing assessments are needed.

Dr. Turcotte, Dr. Liu, Dr. Levine, and Dr. Nathan each reported no financial disclosures.

Chicago – Survivors of childhood cancers face several later risks from treatment, and investigators presented studies evaluating risks in three specific areas – secondary neoplasms, premature menopause, and neurocognitive function – at the annual meeting of the American Society of Clinical Oncology.

Discussant Paul Nathan, M.D., of The Hospital for Sick Children in Toronto, said “the whole purpose” of research in this area “is to start to understand the predictors and modifiers of late effects” and then to design risk assessment tools and interventions to reduce long-term toxicity. These interventions include modification of chemotherapy and radiation doses, protective strategies, and disease risk stratification to adjust intensity of therapies.

Other strategies are to use behavioral interventions directed at improving compliance with follow-up to detect problems earlier and the use of real-time monitoring, such as with smart phones or fitness trackers. He said one limitation of this sort of research and implementing interventions to reduce late toxicities is that “you need time to document long-term outcomes.” So tracking newer therapies, such as proton beam radiation, small molecule drugs, and immunotherapy, is “going to take time, perhaps decades, before you understand their impact on patients.”

Risk of secondary neoplasms reduced

Risk-stratifying of disease “has allowed us to make attempts to minimize late effects by modifying therapy over time in certain subgroups of lower-risk patients,” said Dr. Lucie Turcotte of the University of Minnesota in Minneapolis.

To study the effects of these changes, she determined the risk of certain subsequent malignant or benign neoplasms over three periods of therapeutic exposure among 23,603 5-year survivors of childhood cancers diagnosed at less than 21 years of age from 1970 to 1999, drawing from the cohort of the Childhood Cancer Survivor Study (CCSS).

CHICAGO – A simple Web-based mobile application (web-app) improved survival time and quality of life of patients with advanced lung cancer, according to a randomized study presented at the annual meeting of the American Society of Clinical Oncology.

The study was stopped at the planned interim survival analysis that occurred after 121 evaluable patients because of survival benefit favoring the web-app arm. The application, called Moovcare, allowed patients to report symptoms over time and stay in close touch with their care providers after their initial surgery, chemotherapy, or radiation therapy.

“The 1-year survival was 75% in the Moovcare vs. 49% in the control arm,” said lead author Dr. Fabrice Denis of the Institut Inter-régional de Cancérologie Jean Bernard in LeMans, France, in a press conference.

Dr. Denis identified several reasons why a web-app could be useful in treating patients with lung cancer. Even with more than 1 million lung cancer deaths a year worldwide, there is no standard follow-up, and relapses do not occur on a 3 or 6-month schedule of planned visits. So patients often wait several weeks until their next visit to report symptoms indicative of a relapse. They may also be reluctant to report symptoms because of shame over how they contracted the disease, for example, from smoking. And patients are often hesitant to “bother” the doctor with symptoms between visits. All these reasons can contribute to suboptimal therapy and worse outcomes.

Investigators designed Moovcare to allow patients to report symptoms weekly, facilitating early detection of relapse or dangerous medical conditions and triggering early supportive care. They compared the web-app to a control of usual, nonpersonalized follow-up in a French multicenter prospective, randomized trial.

Patients (n = 121) with stage II/node-positive to stage IV (90% stage III/IV) nonprogressive small cell or non–small cell lung cancer were randomly assigned 1:1 to the two arms of the trial. They had to have Internet access, prior experience with email, performance status of 0-2, and an initial symptom score less than 7. Patients could be taking tyrosine kinase inhibitors or on maintenance therapy. Monitoring visits were the same for both groups every 3 months or more frequently. Patients in the control arm received more frequent computed tomographic (CT) imaging than did ones in the web-app arm, and CT scans could be performed at any time in either group based on the investigator’s clinical judgment, or in the case of the web-app, as suggested by patient report in the algorithm.

The median follow up was 9 months. Relapse rates were close to 50% for both groups. The 1-year survival of 75% in the Moovcare to 49% in the control arm gave a 1-year absolute survival increase of 26%. Median survival was 19 months vs. 12 months, a 7-month improvement in median survival for the Moovcare arm. The hazard ratio for death in the web-app arm, compared with the control arm was 0.325 (95% confidence interval, 0.157-0.672; P = .0025).

When they relapsed, 77% of patients in the web-app arm had a good performance status, compared with 33% in the control arm. “This led to 74% of patients receiving optimal therapy in the Moovcare arm vs. 33% in the control arm,” Dr. Denis said. “And the number of imaging [procedures] was reduced by 50% per patient per year.”

Overall quality of life was better in the web-app arm, as assessed using standard quality of life questionnaires.

Moovcare works by having patients or their relatives report 12 symptoms weekly (for example, asthenia, cough, dyspnea, anorexia, etc.) using a smartphone, tablet, or computer. An algorithm analyzes an association of symptoms and triggers email alerts to health care providers if relapse or dangerous medical conditions may be occurring. Providers follow up alerts by phone and schedule visits and imaging. “The sensitivity of the algorithm was high and was validated in two prospective studies,” Dr. Denis said. Sensitivity was 86%-100%.

Moovcare allowed earlier detection of relapse and improved overall survival for three reasons. “It allowed higher performance status at relapse, leading to more optimal therapy for relapsing patients. Dangerous medical conditions were detected earlier and treated earlier. It favored earlier supportive care, which improved quality of life. Less imaging was needed and performed at the right time,” Dr. Denis said.

Patients were monitored on a weekly basis, allowing more personalized care. The Moovcare web-app has been evaluated prospectively in about 300 patients, providing a high level of evidence of its utility in improving outcomes for patients with advanced lung cancer.

Press conference moderator Dr. Patricia Ganz commented that Moovcare is an example of a new way to improve the delivery of high-quality care to patients. “If we had a drug or some new intervention that caused this level of survival benefit, wouldn’t we want to go out and use it?” she asked. “This is a tremendous advance. This is personalized medicine. This is really tailoring it to the patient, and you can see how simple it is to collect this kind of data from the patient and then bring them in in between what would have been a scheduled visit.” She said the app overcomes the barrier of patients putting off reporting symptoms until their next visit or their reluctance to “bother the doctor.”

She said the app alerts the health care team to potential problems and prompts them to “use tests when appropriate, not on a schedule, [which] leads to avoidance of waste in the follow-up of care of our patients.”

CHICAGO – Aggressive care for most patients with incurable solid tumors continued in the final 30 days of life, and one-third died in the hospital, a recent, large retrospective study of health claims data on more than 28,000 patients shows, and there was no decrease in this practice over a recent 7-year period, despite recommendations to the contrary.

“Aggressive medical care for patients with incurable cancers at the end of life is widely recognized to be harmful to patients and their families,” Dr. Ronald Chen of the University of North Carolina at Chapel Hill said at the annual meeting of the American Society of Clinical Oncology.

As part of the Choosing Wisely campaign in 2012, the American Society of Clinical Oncology’s first recommendation was not to use cancer-directed therapy for patients with solid tumors when there is no strong evidence supporting the clinical value of further anticancer treatment. It also recommended more use of palliative and supportive care. However, the impact of these recommendations on clinical care in younger cancer populations was unknown.

In a study of patients younger than 65 years with solid tumors who died in 2007-2014, Dr. Chen and his associates studied the use of several items that could be considered to be aggressive therapy. They included chemotherapy, radiotherapy, invasive procedures, emergency room visits, hospitalization, intensive care use, and in-hospital death. Patients had any of five common metastatic diseases: breast, lung, prostate, colorectal, or pancreatic cancers (n = 5,855; 12,764; 1,508; 5,207; 3,397, respectively).

The source material for the study was large commercial insurance claims data on patients across 14 states. Investigators evaluated the proportion of patients who received forms of aggressive care in the final 30 days of life.

“Overall, the findings are remarkably consistent across the five diseases. And overall, about three-quarters of patients received at least one form of aggressive care in the last 30 days of life,” Dr. Chen said (range, 71.2%-75.9% of patients). Almost two-thirds of patients (61.6%-65.1%) were admitted to the hospital or went to the emergency department, about 20% of patients (15.9%-20.6%) received intensive care, and one-third of patients (30.3%-35.4%) died in the hospital instead of at home. About 25%-30% of patients received chemotherapy or an invasive procedure, such as a biopsy or a form of surgery. Radiation therapy was used the least and was administered to about 5%-20% of patients.

Looking at the overall use of aggressive care for each of the cancers studied, the researchers found virtually no trend over time, that is, from the second quarter of 2012, when ASCO issued its Choosing Wisely guidelines, through the fourth quarter of 2014. For each of the cancers, aggressive care was delivered to just about 75% of patients across all quarters. Looking further back, the investigators found the same proportions of patients receiving aggressive care in the last 30 days of life during the years 2007-2011.

They also looked specifically at the use of chemotherapy and did not find a change after the Choosing Wisely recommendations, “nor did we find a significant increase in the use of hospice from before 2012 to afterward,” Dr. Chen said. “Additional efforts are critically needed to improve end-of-life care for patients with terminal cancers to ensure that the care provided meets the goals and preferences of patients and their families.” Fewer than one-fifth of patients used hospice care.

Press conference moderator Dr. Patricia Ganz, director of cancer prevention and control research at the Jonsson Comprehensive Cancer Center of the University of California, Los Angeles, called the study “interesting and important for several reasons.” First, there have been very few studies on the topic on the younger (up to age 65) cancer population although the SEER-Medicare database has been used as a source of claims data for older cancer patients. One may like to know if the younger population is being treated more aggressively than the older population is, as well as other patterns of care.

“Giving chemotherapy in the last 30 days of life has been a coping measure for a very long time,” she said. “It’s been nationally looked at as one of our failures in giving good end-of-life care, and so the fact that there wasn’t any dramatic change at 2012 doesn’t bother me in the sense that we’ve been talking about this for a very long time, and we haven’t seen any movement.” She said there is a lot left to do in delivering high quality end-of-life care.

Dr. Chen said more education of both patients and physicians is needed to improve conversations about goals and expectations, as well as palliative care and hospice. These types of care need to be made more accessible, he said.

Limitations of the study include a lack of information on the cause of death (whether related to the cancer, the treatment received, or other), and researchers did not review the medical records to investigate the medical reasons for the use of aggressive care near the end of life.

CHICAGO – Aggressive care for most patients with incurable solid tumors continued in the final 30 days of life, and one-third died in the hospital, a recent, large retrospective study of health claims data on more than 28,000 patients shows, and there was no decrease in this practice over a recent 7-year period, despite recommendations to the contrary.

“Aggressive medical care for patients with incurable cancers at the end of life is widely recognized to be harmful to patients and their families,” Dr. Ronald Chen of the University of North Carolina at Chapel Hill said at the annual meeting of the American Society of Clinical Oncology.

As part of the Choosing Wisely campaign in 2012, the American Society of Clinical Oncology’s first recommendation was not to use cancer-directed therapy for patients with solid tumors when there is no strong evidence supporting the clinical value of further anticancer treatment. It also recommended more use of palliative and supportive care. However, the impact of these recommendations on clinical care in younger cancer populations was unknown.

In a study of patients younger than 65 years with solid tumors who died in 2007-2014, Dr. Chen and his associates studied the use of several items that could be considered to be aggressive therapy. They included chemotherapy, radiotherapy, invasive procedures, emergency room visits, hospitalization, intensive care use, and in-hospital death. Patients had any of five common metastatic diseases: breast, lung, prostate, colorectal, or pancreatic cancers (n = 5,855; 12,764; 1,508; 5,207; 3,397, respectively).

The source material for the study was large commercial insurance claims data on patients across 14 states. Investigators evaluated the proportion of patients who received forms of aggressive care in the final 30 days of life.

“Overall, the findings are remarkably consistent across the five diseases. And overall, about three-quarters of patients received at least one form of aggressive care in the last 30 days of life,” Dr. Chen said (range, 71.2%-75.9% of patients). Almost two-thirds of patients (61.6%-65.1%) were admitted to the hospital or went to the emergency department, about 20% of patients (15.9%-20.6%) received intensive care, and one-third of patients (30.3%-35.4%) died in the hospital instead of at home.
