TBD Meeting (3035-20)

Adding pembrolizumab to standard chemotherapy significantly improved progression-free survival for patients with metastatic triple-negative breast cancer, but only if their tumors were enriched with comparatively high levels of the target programmed death ligand-1 (PD-L1), results of the KEYNOTE 355 trial showed.

Among 843 patients with triple-negative breast cancer (TNBC) randomized to receive either investigator’s choice of chemotherapy plus pembrolizumab (Keytruda) or placebo, patients whose tumors had a PD-L1 combined positive score (CPS) of 10 or higher had a median progression-free survival (PFS) of 9.7 months when treated with pembrolizumab and chemotherapy, compared with 5.6 months among patients treated with chemotherapy and placebo, reported Javier Cortes, MD, PhD, from the Vall d´Hebron Institute of Oncology in Madrid and Barcelona.

However, among patients with CPS between 1 and 10, there was no significant difference in PFS between the treatment arms, he said in a presentation made as a part of the 2020 American Society of Clinical Oncology virtual scientific program.

“The inclusion of taxanes and a known taxane/platinum–based regimen permits assessment of the clinical benefit of pembro in combination with several routinely used chemo partners. A trend toward improved efficacy with PD-L1 enrichment was observed in patients treated with pembro plus chemo. The improvement in progression-free survival with chemotherapy and pembrolizumab was observed across patient subgroups,” said Dr. Cortes.

In the KEYNOTE-522 study, adding pembrolizumab to chemotherapy in the neoadjuvant setting increased the likelihood that women with stage III or early node-positive TNBC would have a pathologic complete response and sustained clinical benefit.

KEYNOTE-355 examined whether pembrolizumab in combination with chemotherapy could provide additional benefit over chemotherapy alone in patients with previously untreated locally recurrent inoperable or metastatic TNBC.

Patients with previously untreated metastatic triple-negative breast cancer who had at least 6 months between definite surgery or last dose of adjuvant chemotherapy (whichever came last) and first disease recurrence were stratified by study chemotherapy received, tumor PD-L1 expression at baseline, and prior treatment with the same class of chemotherapy in the neoadjuvant and/or adjuvant setting.

The patients were then randomized in a 2:1 ratio to pembrolizumab plus chemotherapy based on the investigator’s choice of nab-paclitaxel, paclitaxel, or carboplatin-gemcitabine (562 patients) or to chemotherapy alone (281).

Pembrolizumab and placebo were administered in a double-blind fashion for up to 35 doses. Chemotherapy was given at the investigator’s discretion according to local guidelines. This trial was not powered or designed to compare differential efficacy of the various chemotherapy regimens, Dr. Cortes noted.

The trial had dual primary endpoints of PFS in patients with PD-L1–positive tumors (CPS > 10 and > 1) and in the intention-to-treat population, and overall survival both in PD-L1-positive patients and the ITT population. Overall survival results will be reported at a later date.

As noted before, the primary endpoint was met in the population of patients with CPS higher than 10, with median PFS of 9.7 among those receiving pembrolizumab versus 5.6 months among those receiving placebo, and an estimated 1 year PFS of 39.1% versus 23% for controls, translating into a hazard ratio for progression on pembrolizumab of 0.65 (P = .0012).

In the patients with CPS higher than 1, however, the median PFS was 7.6 months with pembrolizumab compared with 5.6 months with placebo, translating into a hazard ratio of 0.74. However, the results did not meet the prespecified boundary for significance. Because of this, the statistical significance in the ITT population was not tested.

“In patients with PD-L1 CPS 10 or higher tumors, the benefit of pembro/chemo on progression-free survival was generally consistent across most predefined subgroups, including eight geographic regions, ECOG performance status, on-study chemo, and prior treatment with the same class of chemo,” Dr. Cortes said.

Treatment-related adverse events occurred in 96.3% of the patients on pembrolizumab and 95% of patients on placebo. Grade 3 or greater adverse events occurred in 68.1% versus 66.9%, respectively. Two patients in the pembrolizumab arm died from a treatment-related event. There were no treatment-related deaths in the placebo arm.

The most common events were those typically associated with chemotherapy, including anemia, neutropenia, nausea, alopecia, fatigue, decreased neutrophil counts, and elevated liver transaminases. Immune-mediated adverse events of any grade occurred in 25.6% of patients in the pembrolizumab arm versus 6% of controls; none of these events were fatal.

“What is clear in this study is that again we’re seeing efficacy of pembrolizumab in combination with chemotherapy increases with increases in CPS,” according to the invited discussant Catherine M. Kelly, MB, BCh, from University College Dublin and Mater Misericordiae University Hospital in Dublin.

“The results from today’s KEYNOTE-355 appear consistent in terms of progression-free survival. However, it is ‘watch this space’ until we get overall survival data before we can make any further comparisons,” she added.

Questions that still need to be answered include which is the best test for measuring PD-L1, whether patients with CPS of 1 or more but less than 10 benefit from the treatment, which of the available chemotherapy regimens is the best partner for pembrolizumab, how to treat patients who don’t respond to the combination, and what are the implications for PD-1/PD-L1 inhibitors in late-stage disease if they are approved in the neoadjuvant or adjuvant setting, Dr. Kelly said.

The study was funded by Merck. Dr. Cortes disclosed honoraria from, a consulting/advisory role for, and institutional research funding from Merck and others. Dr. Kelly disclosed honoraria from MSD Oncology and others, and travel expenses from Pfizer and Roche.

Is maintenance therapy with an immune checkpoint inhibitor a good idea for patients with advanced bladder cancer who do not progress after initial chemotherapy?

Yes, and furthermore this approach offers “a new first-line standard of care for advanced urothelial cancer,” said Thomas Powles, MD, professor of genitourinary oncology and director of the Barts Cancer Centre in London.

Dr. Powles was discussing “first-line maintenance therapy” with avelumab (Bavencio, EMD Serono and Pfizer) from the JAVELIN Bladder 100 trial.

Results from this trial will be presented at the plenary session of the 2020 annual meeting of the American Society of Clinical Oncology, held virtually because the coronavirus pandemic. ASCO chief medical officer Richard Schilsky, MD, PhD, highlighted this abstract as one of three from the plenary session that were “practice changing.”

Dr. Powles provided a glimpse of the results at a premeeting press briefing.

The trial involved 700 patients who had not progressed after at least four cycles of first-line, platinum-based chemotherapy. Maintenance therapy with avelumab improved overall survival by 7.1 months when compared with best supportive care (BSC) alone.

The median OS was 21.4 months for avelumab plus BSC versus 14.3 months for BSC alone (hazard ratio, 0.69; P = .0005).

An expert not involved with the study was impressed with the outcome.

“The data are encouraging and we look forward to FDA review, and hopefully approval [in this setting],” said Padmanee Sharma, MD, PhD, a genitourinary medical oncologist at the University of Texas MD Anderson Cancer Center, Houston.

Avelumab is already approved for use in advanced urothelial cancer, but in a second-line setting, like a number of other immune checkpoint inhibitors.
 

“Instead of waiting for cancer to return”

Dr. Powles commented that about 65%-75% of patients with advanced urothelial cancer have disease control with first-line chemotherapy, but that progression-free survival (PFS) and OS are “short” because of chemoresistance.

Many patients do not receive second-line treatment with immunotherapy and only a “minority” achieve durable clinical benefit, he added.

“Instead of waiting for the cancer to return,” which it will do “quickly,” Dr. Powles suggested that maintenance with immunotherapy should become the standard of care.

“Our findings should give hope to many patients with advanced urothelial cancer who face a very challenging and difficult condition,” coauthor Petros Grivas, MD, PhD, clinical director of the Genitourinary Cancers Program at the Seattle Cancer Care Alliance, said in a statement. He was the global coprincipal investigator of the JAVELIN Bladder 100 trial.

“People with advanced urothelial cancer generally have a poor prognosis, and most experience cancer progression (growth) within 8 months after initiation of first-line chemotherapy,” he said.

“We are very excited with these results, which indicate that immunotherapy with avelumab first-line maintenance could offer a new treatment option that helps patients live longer. Even if this is likely not a complete cure and may cause potential side effects in some patients, the significant prolongation of overall survival is clearly a remarkable improvement, while many treated patients may not experience significant side effects from this approach,” he added.

The safety profile was “manageable” and consistent with other studies of avelumab, Dr. Powles reported.

All-causality adverse events (AEs) were reported at any grade in 98% versus 77.7% in the avelumab plus BSC versus BSC-alone groups; AEs of grade 3 or higher were 47.4% vs 25.2%. The most frequent grade ≥3 AEs were urinary tract infection (4.4% vs. 2.6%), anemia (3.8% vs. 2.9%), hematuria (1.7% vs. 1.4%), fatigue (1.7% vs. 0.6%), and back pain (1.2% vs. 2.3%).

The results from JAVELIN with avelumab show the “largest survival benefit” seen so far in advanced urothelial cancer in the maintenance setting, according to ASCO press materials.

Has there ever been a survival benefit found with maintenance therapy?

No, according to a 2019 review in Future Oncology. Three prospective, randomized, controlled trials (of vinflunine, sunitinib, and lapatinib, respectively) did not reveal any significant oncologic benefit vs placebo.

But in a phase 2, randomized, controlled trial involving 107 patients, maintenance pembrolizumab provided longer PFS, compared with placebo (5.4 vs 3.2 months, HR, 0.64; 95% confidence interval, 0.41-0.98).

This pembrolizumab trial showed a “similar PFS hazard ratio” to that seen with avelumab in JAVELIN, Dr. Powles commented, noting however that the pembrolizumab trial was not designed to look at survival.
 

Even better response among PD-L1-positive patients

JAVELIN patients had unresectable locally advanced or metastatic urothelial carcinoma and were treated with gemcitabine with either cisplatin or carboplatin.

Just over half (51%) of these patients had tumors that were PD-L1 positive.

The maintenance therapy strategy was even more effective in these patients. Avelumab plus BSC significantly prolonged OS versus BSC alone in patients with PD-L1-positive tumors (HR, 0.56; 1-sided P = .0003). Median OS was not reached versus 17.1 months, respectively.

An OS benefit was also observed across all prespecified subgroups, including those patients with visceral metastases.

Commenting on the study, Dr. Sharma said she would like to see more detailed outcome data related to the number of chemotherapy cycles administered (the range was 4 to 6) and information on the amount of time between the end of chemo to the start of avelumab. Dr. Powles commented that his international team has not looked at number of cycles and outcome, nor the time from completion of chemotherapy and randomization. “They are both valid questions for the future,” he said.

The study was funded by Pfizer. Dr. Powles and many of the coauthors have financial relationships with Pfizer and other pharmaceuticals. Dr. Sharma has disclosed no relevant financial relationships.

No, according to a 2019 review in Future Oncology. Three prospective, randomized, controlled trials (of vinflunine, sunitinib, and lapatinib, respectively) did not reveal any significant oncologic benefit vs placebo.

But in a phase 2, randomized, controlled trial involving 107 patients, maintenance pembrolizumab provided longer PFS, compared with placebo (5.4 vs 3.2 months, HR, 0.64; 95% confidence interval, 0.41-0.98).

This pembrolizumab trial showed a “similar PFS hazard ratio” to that seen with avelumab in JAVELIN, Dr. Powles commented, noting however that the pembrolizumab trial was not designed to look at survival.
 

Even better response among PD-L1-positive patients

JAVELIN patients had unresectable locally advanced or metastatic urothelial carcinoma and were treated with gemcitabine with either cisplatin or carboplatin.

Just over half (51%) of these patients had tumors that were PD-L1 positive.

The maintenance therapy strategy was even more effective in these patients. Avelumab plus BSC significantly prolonged OS versus BSC alone in patients with PD-L1-positive tumors (HR, 0.56; 1-sided P = .0003). Median OS was not reached versus 17.1 months, respectively.

An OS benefit was also observed across all prespecified subgroups, including those patients with visceral metastases.

Commenting on the study, Dr. Sharma said she would like to see more detailed outcome data related to the number of chemotherapy cycles administered (the range was 4 to 6) and information on the amount of time between the end of chemo to the start of avelumab. Dr. Powles commented that his international team has not looked at number of cycles and outcome, nor the time from completion of chemotherapy and randomization. “They are both valid questions for the future,” he said.

The study was funded by Pfizer. Dr. Powles and many of the coauthors have financial relationships with Pfizer and other pharmaceuticals. Dr. Sharma has disclosed no relevant financial relationships.

Patients with COVID-19 and progressing cancer had a fivefold increase in the risk of 30-day mortality, compared with COVID-19–positive cancer patients who were in remission or had no evidence of cancer, according to data from the COVID-19 and Cancer Consortium (CCC19) registry.

Other independent risk factors for death in patients with COVID-19 and cancer were older age, male sex, former smoking, number of comorbidities, Eastern Cooperative Oncology Group (ECOG) performance status of 2 or greater, and treatment with hydroxychloroquine plus azithromycin.

In fact, patients who received hydroxychloroquine and azithromycin had a nearly threefold higher risk of death than did patients who had not received the combination. However, this finding was of “uncertain validity due to a high risk of residual confounding; for example, patients receiving this combination were more likely to have severe disease or more likely to be hospitalized,” said Jeremy L. Warner, MD, of Vanderbilt University Medical Center in Nashville, Tennessee.

Dr. Warner presented these findings in an online press briefing. Additional findings from the CCC19 registry are set to be presented as part of the American Society of Clinical Oncology (ASCO) virtual scientific program. The findings were also published in The Lancet.

‘Severe impact’ in cancer patients

“For people with cancer, the impact of COVID-19 is especially severe, whether they have been exposed to the virus or not. Patients with cancer are typically older adults, often with other underlying conditions, and their immune systems may be suppressed by the cancer, or due to chemotherapy, radiation, or other treatment,” commented ASCO President Howard A. Burris III, MD, who moderated the press briefing but was not involved in the study of CCC19 registry data.

“ASCO members tell us that they have had to delay or modify treatment plans to reduce patients’ risk of infection, and we’re unclear what the impact of these changes will be. Delays in cancer screening and diagnosis are also a major concern,” Dr. Burris continued.

“This does confirm reports that have come out from other centers, including other parts of the world, where they have found that people who have cancer and COVID-19 have a worse outcome,” said Andrew T. Chan, MD, MPH, of Massachusetts General Hospital in Boston, who was not involved in the research.

Dr. Chan’s group has developed a COVID-19 symptom study app with the aim of defining whether people living with cancer are at increased risk for infections, in addition to whether cancer is an independent risk factor for COVID-19 severity or mortality.

“Using data from our app, we were able to show that people who reported living with cancer did have a higher risk of developing COVID and were more likely to be hospitalized related to COVID,” Dr. Chan said in an interview.
 

Study details

The CCC19 registry collects information from 104 participating institutions in the United States and Canada, as well as anonymous data from individuals in the United States, Argentina, Canada, the European Union, and the United Kingdom.

The sample of 928 patients Dr. Warner presented was evenly balanced by sex. The median age was 66 years, and 30% of patients were aged 75 years or older.

In all, 39% of patients were on active anticancer therapy, and 43% had measurable disease. Breast cancer was the most common diagnosis, followed by prostate cancer, gastrointestinal cancers, lymphomas, and thoracic cancers.

Two-thirds of the patients (68%) had an ECOG performance status of 0 or 1, 8% had a performance status of 2, and 5% a status of 3 or 4. The remaining patients had unknown performance status.

Slightly more than half of patients (52%) were never smokers, 37% were former smokers, and 5% were current smokers. The remaining 6% of patients had unknown smoking status.

At a median follow-up of 21 days, 121 patients (13%) had died. All deaths occurred within 30 days of COVID-19 diagnosis. Among patients who died, 78 were male, 64 were former smokers, 70 were aged 75 years or older, 41 had active stable or responding cancer, 25 had progressing cancer, and 42 had an ECOG performance status of 2 or higher.

In all, 466 patients were hospitalized, and 106 in this group (23%) died. Among the 132 patients admitted to an ICU, 50 (38%) died, including 27 patients aged 75 years or older, and 15 with an ECOG performance status of 2 or greater. Of the 116 patients who required intubation, 50 (43%) died, including 26 who were 75 years or older, and 11 who had a performance status of 2 or greater.

It’s early days yet, and a larger sample size with longer follow-up will be needed to get a more complete picture of how COVID-19 affects specific patient subsets over time, Dr. Warner said.

ASCO has established its own COVID-19 registry to collect both near-term and longitudinal data during the pandemic.

“We’ll be able to learn about both how the pandemic has impacted delivery of cancer care, as well as the longer-term effects of COVID-19 on cancer patients and understand what care approaches are working best,” said Richard L. Schilsky, MD, chief medical officer and executive vice president of ASCO, during the briefing.

The study of CCC19 registry data was supported in part by the National Institutes of Health and the American Cancer Society. Dr. Warner disclosed stock/ownership in HemOnc.org, consulting for IBM and Westat, and travel expenses from IBM. Dr. Burris, Dr. Schilsky, and Dr. Chan reported no disclosures relevant to the study.

Adjuvant therapy with osimertinib was associated with a nearly 80% reduction in the risk of disease recurrence or death in patients with stage IB-IIIA non–small cell lung cancer (NSCLC) bearing EGFR mutations, results of the ADAURA trial showed.

The randomized, phase 3 trial was a comparison of osimertinib treatment with placebo following complete resection of localized or locally advanced NSCLC with negative margins. The trial was unblinded early and halted on the recommendation of the independent data-monitoring committee, due to the efficacy of osimertinib.

“If I were on the committee, I would have done the same thing. These are extraordinary results,” said study investigator Roy S. Herbst, MD, PhD, chief of medical oncology at the Yale Cancer Center and Smilow Cancer Center at Yale University in New Haven, Conn.

Dr. Herbst is scheduled to present results from ADAURA as part of the American Society of Clinical Oncology virtual scientific program.

In an online briefing prior to the meeting, Dr. Herbst said the impressive results reminded him of a lesson imparted by his mentor, the late Isaiah Fidler, DVM, PhD.

“He taught me, he taught all of us, that metastasis is a spread of tumor that kills patients,” Dr. Herbst said. “Drugs such as this, based on biology, given to patients at the earliest possible time, prevent those metastases and allow patients to live longer and with a better quality of life.”

Results from the ADAURA trial provide compelling evidence of the benefit of adjuvant osimertinib for a select group of patients, according to Tina Cascone, MD, PhD, assistant professor in the department of thoracic head and neck medical oncology at The University of Texas MD Anderson Cancer Center in Houston. She was not involved in the study.

“These are unprecedented results for a potentially curable, resected population of patients,” Dr. Cascone said in an interview. “This definitely has the potential to shift the paradigm in the treatments that we have available for patients with resected disease. It’s very important to emphasize how much we’ve learned from the metastatic setting and how we’re bringing what we’ve learned into early stage disease.”

 

High recurrence rates

An estimated 30% of patients with NSCLC present with resectable disease at diagnosis, but 5-year recurrence rates following surgery and cisplatin-based adjuvant chemotherapy remain high, ranging from 45% among patients with stage IB disease to 62% for patients with stage II NSCLC and 76% for patients with stage III disease, Dr. Herbst noted.

Osimertinib is a third-generation tyrosine kinase inhibitor (TKI) targeted to EGFR. It has been shown to offer improvements in both progression-free survival and overall survival compared with the EGFR-TKIs erlotinib and gefitinib for patients with advanced EGFR-mutated NSCLC, as well as in patients with central nervous system metastases.

Osimertinib’s efficacy and safety profile against advanced disease suggests it may also be effective against early stage disease, a hypothesis the ADAURA trial was designed to test.
 

Study details

The phase 3, randomized, double-blind trial was conducted at centers in the United States, Europe, Asia, and Australia. A total of 682 patients with completely resected stage IB, II, or IIIA NSCLC, with or without planned adjuvant chemotherapy, were enrolled.

After stratification by stage, EGFR mutation, and race (Asian vs. non-Asian), patients were randomized on a 1:1 basis to receive either osimertinib at 80 mg once daily or placebo. The planned treatment duration was a maximum of 3 years.

Members of the independent data-monitoring committee held a meeting in April 2020. Although they had not planned an efficacy analysis at that time, they decided the results were clearly in favor of osimertinib. So they recommended unblinding and halting of the trial.

At the time of unblinding, the study had completed enrollment, and all patients had been followed for at least 1 year.
 

Efficacy and safety

For the primary endpoint of disease-free survival (DFS) in patients with stage II to IIIA disease, the median DFS was not reached for patients assigned to osimertinib, but it was 20.4 months for patients assigned to placebo (hazard ratio, 0.17; P < .0001).

The numbers were similar for the secondary endpoint of DFS in the overall population, including patients with stage IB disease. The median DFS was not reached for patients on osimertinib but was 28.1 months for patients on placebo (HR, 0.21; P < .0001).

DFS was significantly superior with osimertinib across all subgroups in the overall population, including sex, age, smoking status, race, stage, EGFR mutation, and adjuvant chemotherapy (yes or no).

Dr. Herbst said patients tolerated osimertinib well, and the drug’s safety profile was consistent with that already known. There were no adverse events leading to death in the osimertinib arm, and the incidence of grade 3 or 4 adverse events of any kind was low.

In all, 10 patients (3%) in the osimertinib arm were reported to have interstitial lung disease. Prolongation of the QT interval was reported in 22 patients (7%) on osimertinib and 4 patients (1%) in the placebo arm.

The results show that “adjuvant osimertinib provides a highly effective, practice-changing treatment for patients with stage IB, II, IIIA, EGFR mutation-positive non–small cell lung cancer after complete tumor resection,” Dr. Herbst said.

Dr. Herbst disclosed relationships with AstraZeneca, which funded the study, as well as Jun Shi Pharmaceuticals and other companies. Dr. Cascone is the international principal investigator of the NeoCOAST trial evaluating durvalumab, an AstraZeneca product.

For the primary endpoint of disease-free survival (DFS) in patients with stage II to IIIA disease, the median DFS was not reached for patients assigned to osimertinib, but it was 20.4 months for patients assigned to placebo (hazard ratio, 0.17; P < .0001).

The numbers were similar for the secondary endpoint of DFS in the overall population, including patients with stage IB disease. The median DFS was not reached for patients on osimertinib but was 28.1 months for patients on placebo (HR, 0.21; P < .0001).

DFS was significantly superior with osimertinib across all subgroups in the overall population, including sex, age, smoking status, race, stage, EGFR mutation, and adjuvant chemotherapy (yes or no).

Dr. Herbst said patients tolerated osimertinib well, and the drug’s safety profile was consistent with that already known. There were no adverse events leading to death in the osimertinib arm, and the incidence of grade 3 or 4 adverse events of any kind was low.

In all, 10 patients (3%) in the osimertinib arm were reported to have interstitial lung disease. Prolongation of the QT interval was reported in 22 patients (7%) on osimertinib and 4 patients (1%) in the placebo arm.

The results show that “adjuvant osimertinib provides a highly effective, practice-changing treatment for patients with stage IB, II, IIIA, EGFR mutation-positive non–small cell lung cancer after complete tumor resection,” Dr. Herbst said.

Dr. Herbst disclosed relationships with AstraZeneca, which funded the study, as well as Jun Shi Pharmaceuticals and other companies. Dr. Cascone is the international principal investigator of the NeoCOAST trial evaluating durvalumab, an AstraZeneca product.

Quitting smoking prior to a lung cancer diagnosis is associated with a survival benefit, even among patients who recently stopped smoking, according to results of a pooled analysis.

Brett Mulcahy/ThinkStock

The overall survival advantage was significant regardless of how long ago patients had last smoked, including among those who quit within 2 years prior to their diagnosis.

These findings create a “teachable moment” for health care providers in scenarios when patients might be more receptive to a stop-smoking message, according to investigator Aline F. Fares, MD, a clinical research fellow at Princess Margaret Cancer Centre in Toronto.

“Our study can be summarized to patients as, ‘it’s never too late to quit,’ ” Dr. Fares said.

She presented results from this study at the American Society of Clinical Oncology virtual scientific program during a press briefing in advance of the meeting. This year, ASCO’s annual meeting is split into two parts. The virtual scientific program will be presented online May 29-31. The virtual education program will be available Aug. 8-10.
 

Results

Dr. Fares presented data on 35,481 patients with a diagnosis of lung cancer who had been enrolled in 17 studies conducted by the International Lung Cancer Consortium. (Data in the presentation were updated from the abstract.)

At diagnosis, 47.5% of the patients were current smokers, 30% were former smokers, and 22.5% were never smokers.

The risk of death from any cause was cut by 20% among former smokers who quit more than 5 years before their lung cancer diagnosis (P < .001). Patients who quit smoking 2-5 years before diagnosis had a 16% reduction in the risk of death, while those who quit within 2 years of diagnosis had a 12% reduced risk (P < .001 for both comparisons).

The overall survival advantage was evident in this pooled analysis regardless of patient sex, disease stage, histology, or amount of smoking as measured in pack-years, according to Dr. Fares. That said, the overall survival advantage appeared to be even greater among heavier smokers (i.e., greater than 30 pack-years) as compared with lighter smokers.

Lung cancer–specific survival was improved by 15% for patients who quit smoking more than 5 years prior to their diagnosis. For those who had quit more recently, there was a nonsignificant trend toward improvement in this outcome.

Overall survival was higher in never smokers in comparison with current smokers, a finding that was expected based on previous studies, according to Dr. Fares.
 

Implications

These findings could be important to share with individuals who are current smokers at the time of lung cancer screening, according to Maher A. Karam-Hage, MD, medical director of the tobacco treatment program at the University of Texas MD Anderson Cancer Center, Houston.

“The power of this data is that it shows quitting makes a difference, and that it can be more impactful the longer you quit before you get diagnosed,” Dr. Karam-Hage said in an interview.

Negative lung cancer screening results sometimes give individuals the false impression that they are “one of the lucky ones” who won’t get lung cancer and don’t have to quit smoking, according to Dr. Karam-Hage, who is studying the comparative effectiveness of different smoking cessation strategies.

“Now, as part of shared decision making, we can provide people with specific numbers before the scan that [suggest] no matter what the scan comes out with, the earlier they quit, the better off they will be,” he said.

In her presentation, Dr. Fares said that lung cancer screening may be an “interesting time” to address smoking cessation, particularly among patients with a heavier smoking history.

“After a lifetime of smoking, patients often feel it’s too late to quit smoking and that the damage has already been done,” she added.

The International Lung Cancer Consortium studies had multiple supporters. Dr. Fares reported having no disclosures related to the research. One researcher reported relationships with AbbVie, AstraZeneca, MedImmune, Bayer, Bristol-Myers Squibb, Merck, Novartis, Pfizer, Roche Canada, and Takeda. Dr. Karam-Hage reported having no relevant disclosures.

Women with platinum-sensitive relapsed ovarian cancer and a BRCA mutation could see their survival extended by over a year by maintenance therapy with the PARP inhibitor olaparib (Lynparza, AstraZeneca).

The new overall survival (OS) data come from the SOLO2 study and were described as “a significant advance” in a cancer “that has a historically poor prognosis” by Richard Schilsky, MD, senior vice president and chief medical officer of the American Society of Clinical Oncology.

The results were highlighted at a presscast prior to being presented during the virtual scientific program of the 2020 ASCO annual meeting (abstract 6002).

The SOLO2 study randomly assigned almost 300 women with relapsed BRCA-related ovarian cancer that was responding to platinum-based chemotherapy to maintenance therapy with either olaparib or placebo.

Earlier results from this study showed that olaparib was associated with an investigator-assessed progression-free survival (PFS) of 19.1 months, versus just 5.5 months with placebo, as previously reported by Medscape Medical News.

New data from this trial, presented by Andrés Poveda, MD, Initia Oncology, Hospital Quironsalud, in Valencia, Spain, show that olaparib improved median OS by 12.9 months compared to placebo (51.7 months with olaparib vs. 38.8 months with placebo; hazard ratio, 0.74; P = .054).

At 5 years’ follow-up, 42.1% of women taking olaparib were alive, versus 33.2% taking placebo.

In an ASCO press release, Poveda described the improvement in median OS with olaparib as “impressive” and that it offers a “substantial benefit to our patients.

“This study helps usher in a new era of personalized medicine for women with this difficult-to-treat cancer,” he added.

Poveda told reporters that this study is “the first randomized phase 3 trial to provide overall survival data for maintenance PARP inhibitors.

“The finding that 22% of patient in the olaparib group received the study treatment for more than 5 years is unprecedented in the setting of relapsed ovarian cancer,” he added.

The new OS data were welcomed by Konstantin Zakashansky, MD, director of gynecologic oncology at Mount Sinai West, New York, who was not involved in the study.

“PARP inhibitor trials have revolutionized therapy for ovarian cancer in the front line, as well as in the recurrent setting, [with] all of the recently presented trials showing significant improvement in progression free survival,” he said.

“Overall survival data, however, which is considered the most clinically relevant endpoint in oncology trials and remains the ‘gold standard’ because of its relevance and objectivity, have been limited,” he continued.

Zakashansky recalled that when the earlier PFS data from SOLO2 were presented, “questions were raised regarding the clinical uncertainty of the benefit associated with olaparib maintenance, primarily whether the PFS benefit...would translate to a long-term overall survival benefit.”

For him, the current results “answer that question” and offer the “largest improvement in overall survival of any recurrent ovarian cancer patient trial reported to date.”

Schilsky added that the new data confirm that olaparib “should be the standard maintenance therapy for patients with BRCA-related relapsed ovarian cancer responding to platinum-based chemotherapy.”

The drug is already approved for this indication, but the new data showing a significant survival benefit are “comforting” and “good news,” he said.
 

Adverse events with olaparib

Treatment-emergent adverse events seen in the study were “consistent with the known tolerability profile of olaparib,” Poveda commented.

The most common events of any grade were nausea, fatigue/asthenia, and anemia. The most common event of grade ≥3 was anemia.

Adverse events leading to dose interruptions occurred in 50% of patients who received olaparib and 19% of patients who took placebo. Adverse events leading to dose reductions occurred in 28% and 3%, respectively.

Treatment discontinuation because of adverse events was reported in 17% of patients given olaparib and 3% of those in the placebo arm.

The study was funded by AstraZeneca and Merck Sharp & Dohme. Poveda reports a consulting or advisory role with AstraZeneca, Clovis Oncology, PharmaMar, Roche, and Tesaro and receiving expenses from PharmaMar. Many coauthors also report relationships with pharmaceutical companies.

Anxiety and distress related to caring for a cancer patient who lives far away may be alleviated through an intervention that includes video-based coaching sessions with a nurse practitioner or social worker, a randomized study suggests.

AJ_Watt/E+

About 20% of long-distance caregivers had a significant reduction in anxiety and 25% had a significant reduction in distress when they received video coaching sessions, attended oncologist visits via video, and had access to a website specifically designed for their needs.

Adding the caregiver to oncologist office visits made the patients feel better supported and didn’t add a significant amount of time to the encounter, said Sara L. Douglas, PhD, RN, of Case Western Reserve University, Cleveland.

Taken together, these results suggest that fairly simple technologies can be leveraged to help caregivers cope with psychological strains related to supporting a patient who doesn’t live nearby, Dr. Douglas said.

Distance caregivers, defined as those who live an hour or more away from the patient, can experience high rates of distress and anxiety because they lack first-hand information or may have uncertainty about the patient’s current condition, according to Dr. Douglas and colleagues.

“Caregivers’ high rates of anxiety and distress have been found to have a negative impact not only upon their own health but upon their ability to provide high quality care to the patient,” Dr. Douglas said.

With this in mind, she and her colleagues conducted a 4-month study of distance caregivers. Dr. Douglas presented results from the study at the American Society of Clinical Oncology virtual scientific program during a press briefing in advance of the meeting. This year, ASCO’s annual meeting is split into two parts. The virtual scientific program will be presented online on May 29-31, and the virtual education program will be available Aug. 8-10.
 

Study details

The study enrolled 441 distance caregivers of cancer patients, and Dr. Douglas presented results in 311 of those caregivers. (Data in the presentation differ from the abstract.) The caregivers were, on average, 47 years of age. Most were female (72%), white (67%), the child of the patient (63%), currently employed (81%), and new to the distance caregiver role (89%).

The caregivers were randomized to one of three study arms.

One arm received the full intervention, which consisted of four video-coaching sessions with an advanced practice nurse or social worker, videoconference office visits with the physician and patient, and access to a website with information for cancer distance caregivers. A second arm received no video coaching but had access to the website and participated in video visits with the physician and patient. The third arm, which only received access to the website, served as the study’s control group.
 

Results

Dr. Douglas said that the full intervention had the biggest impact on caregivers’ distress and anxiety.

Among distance caregivers who received the full intervention, 19.2% had a significant reduction in anxiety (P = .03), as measured in online surveys before and after the intervention using the PROMIS Anxiety instrument. Furthermore, 24.8% of these caregivers had a significant reduction in distress (P = .02) from preintervention to post intervention, as measured by the National Comprehensive Cancer Network Distress Thermometer. Overall, distress and anxiety scores decreased in this arm.

Distance caregivers who only had physician-patient video visits and website access had a “moderate” reduction in distress and anxiety, Dr. Douglas said. Among these caregivers, 17.3% had an improvement in anxiety from baseline, and 19.8% had an improvement in distress. Overall, distress scores decreased, but anxiety scores increased slightly in this arm.

In the control arm, 13.1% of caregivers had an improvement in anxiety from baseline, and 18% had an improvement in distress. Overall, both anxiety and distress scores increased in this arm.

“While the full intervention yielded the best results for distance caregivers, we recognize that not all health care systems have the resources to provide individualized coaching sessions to distance caregivers,” Dr. Douglas said. “Therefore, it is worth noting that videoconference office visits alone are found to be of some benefit in improving distress and anxiety in this group of cancer caregivers.”

The study results suggest videoconferencing interventions can improve the emotional well-being of remote caregivers who provide “critical support” for cancer patients, said ASCO President Howard A. “Skip” Burris III, MD.

“As COVID-19 forces separation from loved ones and increases anxiety for people with cancer and their caregivers, providing emotional support virtually is more important than ever,” Dr. Burris said in a news release highlighting the study.

This study was funded by the National Institutes of Health and Case Comprehensive Cancer Center. Dr. Douglas reported having no disclosures. Other researchers involved in the study disclosed relationships with BridgeBio Pharma, Cardinal Health, Apexigen, Roche/Genentech, Seattle Genetics, Tesaro, Array BioPharma, Abbvie, Bristol-Myers Squibb, and Celgene. A full list of Dr. Burris’s financial disclosures is available on the ASCO website.

Among distance caregivers who received the full intervention, 19.2% had a significant reduction in anxiety (P = .03), as measured in online surveys before and after the intervention using the PROMIS Anxiety instrument. Furthermore, 24.8% of these caregivers had a significant reduction in distress (P = .02) from preintervention to post intervention, as measured by the National Comprehensive Cancer Network Distress Thermometer. Overall, distress and anxiety scores decreased in this arm.

Distance caregivers who only had physician-patient video visits and website access had a “moderate” reduction in distress and anxiety, Dr. Douglas said. Among these caregivers, 17.3% had an improvement in anxiety from baseline, and 19.8% had an improvement in distress. Overall, distress scores decreased, but anxiety scores increased slightly in this arm.

In the control arm, 13.1% of caregivers had an improvement in anxiety from baseline, and 18% had an improvement in distress. Overall, both anxiety and distress scores increased in this arm.

“While the full intervention yielded the best results for distance caregivers, we recognize that not all health care systems have the resources to provide individualized coaching sessions to distance caregivers,” Dr. Douglas said. “Therefore, it is worth noting that videoconference office visits alone are found to be of some benefit in improving distress and anxiety in this group of cancer caregivers.”

The study results suggest videoconferencing interventions can improve the emotional well-being of remote caregivers who provide “critical support” for cancer patients, said ASCO President Howard A. “Skip” Burris III, MD.

“As COVID-19 forces separation from loved ones and increases anxiety for people with cancer and their caregivers, providing emotional support virtually is more important than ever,” Dr. Burris said in a news release highlighting the study.

Anxiety and distress related to caring for a cancer patient who lives far away may be alleviated through an intervention that includes video-based coaching sessions with a nurse practitioner or social worker, a randomized study suggests.

About 20% of long-distance caregivers had a significant reduction in anxiety and 25% had a significant reduction in distress when they received video coaching sessions, attended oncologist visits via video, and had access to a website specifically designed for their needs.

Adding the caregiver to oncologist office visits made the patients feel better supported and didn’t add a significant amount of time to the encounter, said Sara L. Douglas, PhD, RN, of Case Western Reserve University, Cleveland.

Taken together, these results suggest that fairly simple technologies can be leveraged to help caregivers cope with psychological strains related to supporting a patient who doesn’t live nearby, Dr. Douglas said.

Distance caregivers, defined as those who live an hour or more away from the patient, can experience high rates of distress and anxiety because they lack first-hand information or may have uncertainty about the patient’s current condition, according to Dr. Douglas and colleagues.

“Caregivers’ high rates of anxiety and distress have been found to have a negative impact not only upon their own health but upon their ability to provide high quality care to the patient,” Dr. Douglas said.

With this in mind, she and her colleagues conducted a 4-month study of distance caregivers. Dr. Douglas presented results from the study at the American Society of Clinical Oncology virtual scientific program during a press briefing in advance of the meeting. This year, ASCO’s annual meeting is split into two parts. The virtual scientific program will be presented online on May 29-31, and the virtual education program will be available Aug. 8-10.
 

Study details

The study enrolled 441 distance caregivers of cancer patients, and Dr. Douglas presented results in 311 of those caregivers. (Data in the presentation differ from the abstract.) The caregivers were, on average, 47 years of age. Most were female (72%), white (67%), the child of the patient (63%), currently employed (81%), and new to the distance caregiver role (89%).

The caregivers were randomized to one of three study arms.

One arm received the full intervention, which consisted of four video-coaching sessions with an advanced practice nurse or social worker, videoconference office visits with the physician and patient, and access to a website with information for cancer distance caregivers. A second arm received no video coaching but had access to the website and participated in video visits with the physician and patient. The third arm, which only received access to the website, served as the study’s control group.
