Novel Investigational Topical Lotion with Unique Formulation Targets the Treatment of Plaque Psoriasis
LAVAL, Quebec, Sept. 5, 2017 /PRNewswire/ -- Ortho Dermatologics, a division of Valeant Pharmaceuticals International, Inc. (NYSE: VRX and TSX: VRX), today announced it hassubmitted a New Drug Application (NDA) to the U.S. Food and Drug Administration ( FDA ) for IDP-118 (halobetasol propionate and tazarotene) lotion . IDP-118 is the first and only topical lotion that contains a unique combination of halobetasol propionate and tazarotene for the treatment of plaque psoriasis.
"We are greatly encouraged by the efficacy and safety results of the IDP-118 clinical program and proud of the dedication of our medical and R&D teams who were able to expedite the NDA filing ahead of internal expectations for this promising treatment," said Joseph C. Papa, chairman and CEO, Valeant. "This submission reflects our unwavering commitment to investing in our pipeline to bring forward novel treatment innovations that help improve the lives of our customers and their patients."
Both approved to treat plaque psoriasis, halobetasol propionate and tazarotene, when used separately, are limited to a four-week or less duration of use. Based on existing data from clinical studies, the combination of these ingredients in IDP-118 with a dual mechanism of action, potentially allows for expanded duration of use, with reduced adverse events.
The NDA submitted for IDP-118 includes data from two successful Phase 3 multi-center, randomized, double-blind clinical trials in 418 subjects 18 years of age and older with 3%-12% clinical involvement of the body surface area for plaque psoriasis. In both studies, IDP-118 met the primary efficacy endpoint achieving a "clear" to "almost clear" score and at least a 2 grade improvement based on an Investigator Global Assessment (IGA) at 8 weeks, and clear to almost clear and at least 2 grade improvement during a 4 week follow up visit at week 12. The NDA also includes a long-term safety study with patients followed for one year. The most common adverse events were contact dermatitis (7.4%) and application site pain (2.6%).
The Phase 3 program was preceded by a successful Phase 2 study where the combination product IDP-118, with a treatment success rate of 52.5%, was superior to each of the actives halobetasol propionate and tazarotene as well as the vehicle, which demonstrates the IDP-118 formulation is superior to using the individual actives separately.
