Core Viewpoint - Galapagos NV is set to present new in vitro pharmacological data for its selective TYK2 inhibitor, GLPG3667, at the ACR Convergence 2025, highlighting its differentiation from other TYK2 inhibitors in clinical dose regimens [1][2]. Group 1: Study Overview - GLPG3667 is currently being evaluated in two Phase 3-enabling studies for systemic lupus erythematosus (SLE) and dermatomyositis (DM) [5]. - The GALACELA study is a randomized, double-blind, placebo-controlled trial assessing GLPG3667's efficacy and safety in adults with active SLE over 48 weeks [6]. - The GALARISSO study is also a randomized, double-blind, placebo-controlled trial focusing on GLPG3667's efficacy and safety in adults with DM over 24 weeks [9]. Group 2: Key Findings - At the clinical dose of 150 mg once daily, GLPG3667 demonstrated comparable inhibition of the IFN-α and IL-23 pathways to currently approved TYK2 inhibitors, with a more pronounced inhibition of the IL-12 pathway [7]. - GLPG3667 showed no measurable inhibition of IL-10-mediated signaling at concentrations significantly above clinical levels, unlike other TYK2 inhibitors [7]. - The primary endpoint for the GALACELA study is the proportion of patients achieving the SLE responder index (SRI)-4 response at Week 32, with secondary endpoints including various lupus assessment scores [6][8].
