Janssen Biotech announced that the US Food and Drug Administration (FDA) has approved Tremfya (guselkumab) for the treatment of adults living with moderate to severe plaque psoriasis who are candidates for systemic therapy or phototherapy. Tremfya is the first and only approved biologic therapy that selectively blocks only IL-23, a cytokine that plays a key role in plaque psoriasis. Approval comes after an expedited regulatory review following application of an FDA Priority Review Voucher.
Tremfya is administered as a 100 mg subcutaneous injection every eight weeks, following two starter doses at weeks 0 and 4. In clinical studies, patients receiving Tremfya experienced significant improvement in skin clearance and greater improvement in symptoms of plaque psoriasis including itch, pain, stinging, burning and skin tightness when compared with placebo at week 16. Superior results in skin clearance (PASI 90) were demonstrated with Tremfya compared with Humira (adalimumab) at weeks 16, 24 and 48.
Highlights of Clinical Program:
Tremfya received FDA approval based on results from a clinical development program that included more than 2,000 patients in the Phase 3 VOYAGE 1, VOYAGE 2 and NAVIGATE studies, which have been published in peer-reviewed journals and were presented at the 25th European Academy of Dermatology and Venerology Congress and the 2017 American Academy of Dermatology Annual Meeting.
Results from VOYAGE 1 and VOYAGE 2 demonstrated significant efficacy in patients with moderate to severe plaque psoriasis treated with Tremfya. In clinical studies, at 16 weeks, at least seven out of ten Tremfya-treated patients achieved at least 90 percent clearer skin, and more than 80 percent demonstrated cleared or almost cleared skin. Improvements were also demonstrated with Tremfya in psoriasis involving the scalp and in symptoms of plaque psoriasis including itch, pain, stinging, burning and skin tightness at week 16. Treatment with Tremfya resulted in clearer skin that lasted, as nearly nine out of ten Tremfya-treated patients who achieved PASI 90 at week 28 maintained that response at week 48. Versus Humira, at week 24, more than seven out of ten patients treated with Tremfya reported at least 90 percent clearer skin compared with more than four out of ten patients treated with Humira.
Navigate findings demonstrated the effectiveness of tremfya in patients who had an inadequate response to treatment with Stelara (ustekinumab). At week 28, 31 percent of Tremfya-treated patients were considered cleared or almost cleared versus 14 per cent of Stelara-treated patients 12 weeks after randomization to continue Stelara or transition to Tremfya.
