FDA Approves BMS Plaque Psoriasis Drug
FDA has approved a Bristol Myers Squibb NDA for Sotyktu (deucravacitinib), which is said to be a first-in-class, oral, selective, allosteric tyrosine kinase 2 (TYK2) inhibitor for treating adults with moderate-to-severe plaque psoriasis who are candidates for systemic therapy or phototherapy. Approval is based on data from the Phase 3 POETYK PSO-1 and POETYK PSO-2 clinical trials, which demonstrated superior efficacy of once-daily Sotyktu compared to placebo and twice-daily apremilast (Amgen’s Otezla) in 1,684 patients aged 18 years and older with moderate-to-severe plaque psoriasis.
In the trials, the most common adverse events were upper respiratory infections (19.2% of Sotyktu patients), blood creatine phosphokinase increase (2.7%), herpes simplex (2.0%), mouth ulcers (1.9%), folliculitis (1.7%) and acne (1.4%).
Bristol Myers Squibb says Sotyktu works by binding to the regulatory domain of TYK2, “stabilizing an inhibitory interaction between the regulatory and the catalytic domains of the enzyme. This results in allosteric inhibition of receptor-mediated activation of TYK2 and its downstream activation of Signal Transducers and Activators of Transcription (STATs) as shown in cell-based assays.”
