Pfizer Atopic Dermatitis Drug Approved

Share

FDA has approved a Pfizer NDA for Cibinqo (abrocitinib), an oral Janus kinase 1 inhibitor for treating adults living with refractory, moderate-to-severe atopic dermatitis (AD) whose disease is not adequately controlled with other systemic drug products, including biologics.The drug is approved for recommended doses of 100 mg and 200 mg. However, a 50 mg dose was also approved for patients with moderate renal impairment, certain patients receiving treatment with inhibitors of cytochrome P450 (CYP) 2C19, or patients who are known or suspected to be poor metabolizers of CYP2C19. “For patients with moderate renal impairment who are not responding to 50 mg once daily, 100 mg once daily may also be prescribed,” the company says.

 

Approval was based on data from five clinical trials involving over 1,600 patients. “Across the trials, Cibinqo demonstrated a consistent safety profile and profound improvements in skin clearance, extent of disease, and severity, as well as rapid improvement in itch after two weeks, for some people living with AD versus placebo,” Pfizer says. “In addition, a higher proportion of subjects treated with Cibinqo in two monotherapy trials achieved improvement in itching at week 12 compared to placebo.”
