Two Janus kinase (JAK) inhibitors, Abbvie Inc.'s Rinvoq (upadacitinib) and Pfizer Inc.'s Cibinqo (abrocitinib), have won U.S. FDA approvals for the treatment of people with moderate to severe atopic dermatitis. Reviews of both products for the indication were delayed due to FDA concerns about class risks. Accordingly, each is labeled with a boxed warning regarding risks of serious infection, mortality, malignancy, major adverse cardiovascular events and thrombosis.
Privately held Leo Pharma Inc. has worked its way through a complete response letter issued in April to see the FDA approve Adbry (tralokinumab-ldrm) for treating moderate to severe atopic dermatitis in adults. The CRL noted FDA requests for additional data related to the device component, a prefilled syringe of tralokinumab, but it did not request new efficacy or safety data related to the drug product formulation. In April and on Dec. 28, the company did not provide details on the device-related data that were requested.
