Ortho Dermatologics Gain Psoriasis Lotion Approval

Share

FDA has approved an Ortho Dermatologics NDA for Duobrii (halobetasol propionate and tazarotene) lotion, 0.01%/0.045%, indicated for the topical treatment of plaque psoriasis in adults. The company says that when used separately to treat psoriasis, halobetasol propionate’s (a corticosteroid) use duration is limited by FDA labeling constraints and tazarotene’s (a retinoid) use can be limited due to tolerability concerns. By combining the two in a once-daily moisturizing lotion, the Duobrii formulation “ensures uniform distribution, allowing for simultaneous contact with the skin surface,” the company says.

 

Approval was based on date from a Phase 3 study that demonstrated the lotion was consistently more effective than its individual agents and a vehicle in achieving treatment success and reducing psoriasis signs of erythema, plaque elevation, and scaling at the target lesion, the company says. “In addition, a post-hoc analysis of the data, in which the vehicle effect was removed, showed that the efficacy of Duobrii was superior to the aggregated results of the individual agents, supporting the synergy of the two ingredients when combined in one lotion formulation,” it says.
