The days of strictly classifying rosacea patients as having erythematotelangiectatic, papulopustular, phymatous, or ocular forms of the skin condition are over. At least they should be, according to Julie C. Harper, MD.

“How many people with papules and pustules don’t also have redness?” Dr. Harper, who practices in Birmingham, Ala., said at Medscape Live’s annual Coastal Dermatology Symposium. “If we’re not careful, and we try to classify a person into a subtype of rosacea, we end up treating only part of their rosacea; we don’t treat all of it. We have seen this in the literature,” she added.

“The idea now is to take a phenotypic approach to rosacea. What we mean by that is that you look at the patient, you document every part of rosacea that you see, and you treat according to that,” she continued. “That person with papules and pustules may also have phyma and ocular disease. They may have telangiectasia and persistent background erythema. They may also have flushing.”



Dr. Harper incorporates the mnemonic “STOP” to her visits with rosacea patients.

S stands for: Identify signs and symptoms of the condition. “Listen to the patient for symptoms,” she advised. “We’ve learned to listen to darker skinned patients for what they tell us about erythema, for example, because we may not be able to see it, yet they are experiencing it. They may also have symptomatic burning, itching, and stinging.”

T stands for: Discuss triggers. “Ask patients, ‘what is it that makes your rosacea worse?’ That’s different for everyone,” she said.

O stands for: Agree on a treatment outcome. “Ask, ‘what is it that really bothers you? Are you bothered by the bumps? The redness?’ ” she said.

“The P stands for: Develop a plan that addresses all of that,” she said.

Different treatments for different rosacea symptoms

No one-size-fits-all treatment exists for rosacea. Options that work well for papules and pustules aren’t effective for redness. Similarly, products that work for redness don’t work for telangiectasia.

“Different lesions and signs of rosacea will likely require multiple modes of treatment,” Dr. Harper said. “So, when you evaluate your rosacea patients, if they’re doing great, don’t change their regimen. But if you see somebody who is not well controlled, is there an opportunity for you to come in and add something to that regimen that may make them better? Maybe so.”

Treatment options indicated for papules and pustules include ivermectin, metronidazole, azelaic acid, sodium sulfacetamide/sulfur, modified release doxycycline, minocycline foam, and encapsulated benzoyl peroxide.

Options indicated for persistent background erythema include brimonidine and oxymetazoline, while device-based treatments include the pulsed dye laser, the KTP laser, intense pulsed light, and electrosurgery.
 

Anti-inflammatory action for pustules and papules

A relatively new product indicated for pustules and papules is minocycline 1.5% foam, the only minocycline that is FDA approved to treat rosacea.

“There is no oral minocycline product approved for rosacea yet,” Dr. Harper said. “There is not a known bacterial pathogen in rosacea. Tetracyclines likely work in rosacea by inhibiting neutrophil chemotaxis, inhibiting MMP and thus KLK-5 and LL-37, inhibiting pro-inflammatory cytokines, downregulating reactive oxygen species, and inhibiting angiogenesis.”

In two 12-week, phase 3 randomized studies of 1,522 patients with moderate to severe rosacea, participants were assigned to receive minocycline 5% foam or a vehicle that contained mineral oil and coconut oil.

At week 12, about 50% of patients who received minocycline 5% foam were clear, compared with about 40% of those in the vehicle arm. Also, the reduction of lesion count was about 63% for patients in the treatment group, compared with a reduction of about 54% in the vehicle arm.

Dr. Harper characterized the 63% reduction as “pretty good, but is it good enough or fast enough? I don’t think so, so even with a great drug like this, I would use something else. You can use two medications sometimes to get people better faster. There’s room to bring in something for that background erythema.”

Minocycline 1.5% foam is colored yellow and may stain fabric. “It contains coconut oil, soybean oil, and light mineral oil,” she said. “Most people prefer to use this at bedtime, but you don’t have to.”

Another treatment option is 5% microencapsulated benzoyl peroxide cream, which is FDA approved for inflammatory lesions of rosacea.

“What’s the mechanism of action? Probably not being antimicrobial,” Dr. Harper said. “I think it’s probably at least in part anti-inflammatory, because we have some data to show that it’s killing Demodex [mites]. If Demodex [are] a trigger of inflammation, and we can lessen Demodex, then we could lessen the inflammatory response after that.”

The drug’s approval was based on data from two positive, identical phase 3 randomized, double-blind, multicenter, 12-week clinical trials that evaluated its safety compared with vehicle in 733 people with inflammatory lesions of rosacea (NCT03564119 and NCT03448939).

At week 12, inflammatory lesions of rosacea were reduced by nearly 70% in both trials among those who received 5% microencapsulated benzoyl peroxide cream, compared with 38%-46% among those who received the vehicle. Also, nearly 50% of subjects in the treatment groups were clear or almost clear at 12 weeks, compared with 38%-46% of those who received the vehicle.

Dr. Harper added that about one-quarter of patients in the treatment group of the trials were clear or almost clear by week 4. “That’s pretty fast,” she said, noting that the product’s microencapsulated shell acts as a fenestrated barrier. “It has little openings, which means that it takes a while for the drug to work itself out,” she said. “I think of it as being like a speed bump for benzoyl peroxide delivery. It has to get through this little maze before it lands on the skin. We think that is what has helped with tolerability.”

Oral sarecycline, a narrow spectrum tetracycline that was FDA approved for acne in 2018, may also benefit rosacea patients. In a 12-week, investigator-blinded pilot study, 72 patients with papulopustular rosacea were assigned to receive sarecycline, while 25 received a multivitamin.

By week 12, 75% of patients in the sarecycline group were clear, compared with 16% of those in the multivitamin group, while the inflammatory lesion counts dropped from baseline by 80% and 60%, respectively. Studies of sarecycline for acne have demonstrated similar rates of vertigo, dizziness, and sunburn to those of placebo.

“There were also low rates of gastrointestinal disturbances,” Dr. Harper said. “That’s important in rosacea, because there is no bacterial pathogen.”

Dr. Harper disclosed that she serves as an advisor or consultant for Almirall, BioPharmX, Cassiopeia, Cutanea, Cutera, Dermira, EPI, Galderma, LaRoche-Posay, Ortho, Vyne, Sol Gel, and Sun. She also serves as a speaker or member of a speakers bureau for Almirall, EPI, Galderma, Ortho, and Vyne.

How to handle pesky molluscum contagiosum lesions

Some pediatricians believe that molluscum contagiosum (MC) should not be treated because they usually self-resolve in 6-18 months, but Rebecca Smith, MD, sees things differently.

“If you don’t treat them, they’re going to spread,” Dr. Smith, who practices dermatology in Fort Mill, S.C., said at Medscape Live’s annual Coastal Dermatology Symposium. “They’re going to be itchy, they can spread on the patient themselves and then to others, and they can cause scarring. The prevalence is anywhere from 5% to 11%. That means there are 6 million patients out there, just waiting to come into your clinics.”

To date, no treatment has been approved by the Food and Drug Administration for MC, although a laundry list of agents have been tried, including cantharidin; cryotherapy; curettage with and without imiquimod; sinecatechins ointment, 15%; imiquimod; and retinoids. And there are several treatments that are being investigated.

A 2017 Cochrane review of 22 studies involving 1,650 patients demonstrated that no single intervention has been consistently effective in treating MC. “Most of the studies were actually very low quality,” said Dr. Smith, who was not involved with the analysis. “The one high quality study showed that imiquimod did not work any better than its vehicle.”
 

Investigational treatments

One of the products in the pipeline is VP-102, a proprietary drug-device combination of cantharidin 0.7% administered through a single-use precision applicator, which has been evaluated in phase 3 studies of patients with molluscum aged 2 years and older. It features a visualization agent so that the person applying the drug can see which lesions have been treated. It also contains a bittering agent to mitigate oral ingestion by children.

VP-102, which is being developed by Verrica Pharmaceuticals, is applied once every 21 days in up to 4 applications, and multiple lesions can be treated with one applicator. “It’s a stable concentration with a good shelf life, and two phase 3 randomized studies have shown about a 50% complete clearance of new and existing lesions at day 84,” Dr. Smith said. Those studies enrolled children and adults.

A separate analysis of the same data presented at a meeting in 2019 showed that 77% of patients treated with VP-102 achieved greater than 75% clearance, while 65.8% achieved more than 90% clearance.

The new kid on the block is a gel formulation of a nitric oxide–releasing medication, berdazimer 10.3%, a first-in-class topical treatment being developed by Novan, which can be applied at home. In a multicenter study published in JAMA Dermatology, researchers randomized 444 patients to berdazimer gel 10.3% and 447 to a placebo gel, applied once daily in a thin layer on all MC lesions for 12 weeks. The study was conducted at 55 clinics across the United States between Sept. 1, 2020, and July 21, 2021. The mean age of the patients was about 6.5 years and participants had 3-70 raised MC lesions; those with sexually transmitted MC or MC in the periocular area were excluded. The primary endpoint was complete clearance of MC lesions after 12 weeks of treatment.

At 12 weeks, significantly more patients treated with berdazimer gel achieved complete clearance than those on vehicle (32.4% vs. 19.7%; P < .001). A total of 64 (14.4%) patients in the berdazimer group discontinued treatment because of MC clearance, compared with 40 patients (8.9%) in the vehicle group.

More recently, investigators evaluated autoinoculation vs. 35% trichloroacetic acid (TCA) for the treatment of MC. Autoinoculation involves puncturing the perilesional and lesional skin 5-7 times with an insulin syringe. “This gets a little bit of the virus into the dermis, and you hope to elicit an immune response,” explained Dr. Smith, who was not involved with the study. At 3 months, 80% of patients in the autoinoculation group achieved complete clearance, compared with 62% of those in the TCA group, while recurrence at 6 months was 3% vs. 40%, respectively.

Manual extraction of MC lesions is another option. “I love to pop the cores out with my thumbs,” Dr. Smith said. “You have to pick the patients who can tolerate this, and the MC lesions need to be ripe and ready.”

For ophthalmic lesions, watchful waiting is advisable unless the MC lesions are symptomatic or bothersome or large lesions form on the lid margin, which may cause ocular irritation or even a corneal abrasion. “If a patient presents with a multisite infection that includes ocular lesions, treat lesions on other parts of the body and keep your fingers crossed that a systemic immune response occurs,” she said.

The desired immune response is known as the “BOTE” sign (the beginning of the end), which heralds the clearance of the molluscum infection. This often appears as reddening of all the MC lesions and occasionally as a granulomatous “id-like” reaction especially on the extensor elbows and knees. “When this happens, it often scares the patients,” Dr. Smith said. But she explains that this is a positive development, and that “this means that the lesions are about to self-resolve.”

Dr. Smith disclosed that she serves as a speaker or a member of the speakers bureau for Amgen, CeraVe, EPI, Galderma, InCyte, Lilly, Pfizer, Regeneron, Sanofi Genzyme, and Sun. She also serves as an advisor or consultant for Janssen, Lilly, Regeneron, and Sanofi Genzyme.

The desired immune response is known as the “BOTE” sign (the beginning of the end), which heralds the clearance of the molluscum infection. This often appears as reddening of all the MC lesions and occasionally as a granulomatous “id-like” reaction especially on the extensor elbows and knees. “When this happens, it often scares the patients,” Dr. Smith said. But she explains that this is a positive development, and that “this means that the lesions are about to self-resolve.”

Dr. Smith disclosed that she serves as a speaker or a member of the speakers bureau for Amgen, CeraVe, EPI, Galderma, InCyte, Lilly, Pfizer, Regeneron, Sanofi Genzyme, and Sun. She also serves as an advisor or consultant for Janssen, Lilly, Regeneron, and Sanofi Genzyme.

Some pediatricians believe that molluscum contagiosum (MC) should not be treated because they usually self-resolve in 6-18 months, but Rebecca Smith, MD, sees things differently.

“If you don’t treat them, they’re going to spread,” Dr. Smith, who practices dermatology in Fort Mill, S.C., said at Medscape Live’s annual Coastal Dermatology Symposium. “They’re going to be itchy, they can spread on the patient themselves and then to others, and they can cause scarring. The prevalence is anywhere from 5% to 11%. That means there are 6 million patients out there, just waiting to come into your clinics.”

To date, no treatment has been approved by the Food and Drug Administration for MC, although a laundry list of agents have been tried, including cantharidin; cryotherapy; curettage with and without imiquimod; sinecatechins ointment, 15%; imiquimod; and retinoids. And there are several treatments that are being investigated.

A 2017 Cochrane review of 22 studies involving 1,650 patients demonstrated that no single intervention has been consistently effective in treating MC. “Most of the studies were actually very low quality,” said Dr. Smith, who was not involved with the analysis. “The one high quality study showed that imiquimod did not work any better than its vehicle.”
 

Investigational treatments

One of the products in the pipeline is VP-102, a proprietary drug-device combination of cantharidin 0.7% administered through a single-use precision applicator, which has been evaluated in phase 3 studies of patients with molluscum aged 2 years and older. It features a visualization agent so that the person applying the drug can see which lesions have been treated. It also contains a bittering agent to mitigate oral ingestion by children.

VP-102, which is being developed by Verrica Pharmaceuticals, is applied once every 21 days in up to 4 applications, and multiple lesions can be treated with one applicator. “It’s a stable concentration with a good shelf life, and two phase 3 randomized studies have shown about a 50% complete clearance of new and existing lesions at day 84,” Dr. Smith said. Those studies enrolled children and adults.

A separate analysis of the same data presented at a meeting in 2019 showed that 77% of patients treated with VP-102 achieved greater than 75% clearance, while 65.8% achieved more than 90% clearance.

The new kid on the block is a gel formulation of a nitric oxide–releasing medication, berdazimer 10.3%, a first-in-class topical treatment being developed by Novan, which can be applied at home. In a multicenter study published in JAMA Dermatology, researchers randomized 444 patients to berdazimer gel 10.3% and 447 to a placebo gel, applied once daily in a thin layer on all MC lesions for 12 weeks. The study was conducted at 55 clinics across the United States between Sept. 1, 2020, and July 21, 2021. The mean age of the patients was about 6.5 years and participants had 3-70 raised MC lesions; those with sexually transmitted MC or MC in the periocular area were excluded. The primary endpoint was complete clearance of MC lesions after 12 weeks of treatment.

At 12 weeks, significantly more patients treated with berdazimer gel achieved complete clearance than those on vehicle (32.4% vs. 19.7%; P < .001). A total of 64 (14.4%) patients in the berdazimer group discontinued treatment because of MC clearance, compared with 40 patients (8.9%) in the vehicle group.

More recently, investigators evaluated autoinoculation vs. 35% trichloroacetic acid (TCA) for the treatment of MC. Autoinoculation involves puncturing the perilesional and lesional skin 5-7 times with an insulin syringe. “This gets a little bit of the virus into the dermis, and you hope to elicit an immune response,” explained Dr. Smith, who was not involved with the study. At 3 months, 80% of patients in the autoinoculation group achieved complete clearance, compared with 62% of those in the TCA group, while recurrence at 6 months was 3% vs. 40%, respectively.

Manual extraction of MC lesions is another option. “I love to pop the cores out with my thumbs,” Dr. Smith said. “You have to pick the patients who can tolerate this, and the MC lesions need to be ripe and ready.”

Consider the mnemonic ‘CLEAR’ when counseling acne patients

When counseling patients with acne about a treatment plan, consider the mnemonic “CLEAR,” advises Julie C. Harper, MD, who came up with this aid to use when treating this group of patients.

During a presentation at Medscape Live’s annual Coastal Dermatology Symposium, Dr. Harper, who practices at Dermatology and Skin Care of Birmingham, Ala., elaborated on the mnemonic, as follows:

C: Communicate expectations. “I look right at the acne patient and say, ‘I know you don’t just want to be better; I know you want to be clear,’ ” she said at the meeting. “ ‘That’s my goal for you, too. That may take us more than one visit and more than one treatment, but I am on your team, and that’s what we’re shooting for.’ If you don’t communicate that, they’re going to think that their acne is not that important to you.”

L: Listen for clues to customize the patient’s treatment. “We’re quick to say, ‘my patients don’t do what I recommend,’ or ‘they didn’t do what the last doctor recommended,’ ” Dr. Harper said. “Sometimes that is true, but there may be a reason why. Maybe the medication was too expensive. Maybe it was bleaching their fabrics. Maybe the regimen was too complex. Listen for opportunities to make adjustments to get their acne closer to clear.”

E: Treat early to improve quality of life and to decrease the risk of scarring. “I have a laser in my practice that is good at treating acne scarring,” she said. “Do I ever look at my patient and say, ‘don’t worry about those scars; I can make them go away?’ No. I look at them and say, ‘we can maybe make this 40% better,’ something like that. We have to prevent acne scars, because we’re not good at treating them.”



A: Treat aggressively with more combination therapies, more hormonal therapies, more isotretinoin, and perhaps more prior authorizations. She characterized the effort to obtain a prior authorization as “our megaphone back to insurance companies that says, ‘we think it is worth taking the time to do this prior authorization because the acne patient will benefit.’ ”

R: Don’t resist isotretinoin. Dr. Harper, who began practicing dermatology more than 20 years ago, said that over time, she has gradually prescribed more isotretinoin for her patients with acne. “It’s not a first-line [treatment], but I’m not afraid of it. If I can’t get somebody clear on other oral or topical treatments, we are going to try isotretinoin.”

The goal of acne treatment, she added, is to affect four key aspects of pathogenesis: follicular epithelial hyperproliferation, inflammation, Cutibacterium acnes (C. acnes), and sebum. “That’s what we’re always shooting for,” she said.

Dr. Harper is a past president of the American Acne & Rosacea Society. She disclosed that she serves as an advisor or consultant for Almirall, BioPharmX, Cassiopeia, Cutanea, Cutera, Dermira, EPI, Galderma, LaRoche-Posay, Ortho, Vyne, Sol Gel, and Sun. She also serves as a speaker or member of a speaker’s bureau for Almirall, EPI, Galderma, Ortho, and Vyne.
