Roflumilast is a selective inhibitor of phosphodiesterase 4 (PDE4), the first approved for treating psoriasis, according to manufacturer Arcutis Biotherapeutics. The company announced the approval on July 29. Oral roflumilast (Daliresp ) was approved in 2011 for treating chronic obstructive pulmonary disease (COPD).“It’s a breakthrough topical therapy,” says Mark G. Lebwohl, MD, dean of clinical therapeutics and professor of dermatology, Icahn School of Medicine at Mount Sinai, New York, and principal investigator in trials of topical roflumilast. In an interview, Dr. Lebwohl noted that the treatment significantly reduced psoriasis symptoms in both short- and long-term trials.
In addition, two features of this treatment set it apart from other topical psoriasis treatments, he said. Roflumilast is not a steroid, so does not have the risk for topical steroid-related side effects associated with chronic use, and, in clinical trials, topical roflumilast was effective in treating psoriasis in intertriginous areas, including the buttocks, underarms, and beneath the breasts, which are difficult to treat.
FDA approval is based on data from two phase 3 randomized, double-blind, vehicle-controlled trials, according to Arcutis. The primary endpoint was Investigator Global Assessment (IGA) success, defined as clear or almost clear with at least a two-grade improvement from baseline, and at least a two-grade IGA score improvement from baseline at 8 weeks.
At 8 weeks, 42.4% and 37.5% of the patients treated with topical roflumilast achieved an IGA success rate compared with 6.1% and 6.9% in the control groups, respectively (P < .0001 for both studies).
Treated patients also experienced significant improvements compared with those in the vehicle groups in secondary endpoints in the trials: Those included Intertriginous IGA (I-IGA) Success, Psoriasis Area Severity Index–75 (PASI-75), reductions in itch based on the Worst Itch–Numerical Rating Scale (WI-NRS), and self-reported psoriasis symptoms diary (PSD).
In the studies, 72% and 68% of patients treated with roflumilast met the I-IGA endpoint at 8 weeks versus 14% and 17%, respectively, of those on vehicle (P < .0001 for both studies).
In addition, by week 2, some participants treated with roflumilast had experienced reduced itchiness in both studies. At 8 weeks, among those with a WI-NRS score of 4 or more at baseline, 67% and 69% of the treated patients had at least a four-point reduction in the WI-NRS versus 26% and 33%, respectively, among those on vehicle (P < .0001 for both studies), according to the company.
In general, the cream was well tolerated. There were reports of diarrhea (3%), headache (2%), insomnia (1%), nausea (1%), application-site pain (1%), upper respiratory tract infections (1%), and urinary tract infections (1%). However, Dr. Lebwohl noted that these events were also observed in the control group.
“The study was unequivocal about the improvement in the intertriginous sites,” Dr. Lebwohl said. He contrasts that to the data from other nonsteroidal topicals, which he said can be associated with a rash or irritation in sensitive areas.
Dr. Lebwohl noted that PDE4 is an enzyme that increases inflammation and decreases anti-inflammatory mediators and that inhibiting PDE4 may interrupt some of the inflammation response responsible for psoriasis symptoms, as it has for other conditions such as atopic dermatitis. Data from the 8-week phase 3 trials and yearlong phase 2b, open-label studies support that hypothesis.
“I’m always excited for new psoriasis treatments to broaden our treatment armamentarium,” said Lauren E. Ploch, MD, a dermatologist who practices in Augusta, Ga., and Aiken, S.C., who was asked to comment on the approval.
Even a symptom that seems benign, like itching, Dr. Ploch added, can lead to reduced sleep and increased irritability. Referring to the data on the treatment in the sensitive, intertriginous areas, she noted that the skin in these areas is often thinner, so treatment with steroids can cause further thinning and damage to the skin. If roflumilast doesn’t cause burning, itching, or thinning, it will be a great option to treat these areas, she said in an interview. She was not involved in the trials.
Roflumilast cream will be marketed under the trade name Zoryve, and is expected to be available by mid-August, according to Arcutis.
Roflumilast cream is also under review in Canada for treatment of plaque psoriasis in adults and adolescents.
The studies were funded by Arcutis Biotherapeutics. Dr. Lebwohl reported receiving grant support and consulting fees from Arcutis. Dr. Ploch reports no relevant financial relationships.
