About Povetacicept (ALPN-303) and the RUBY-1 Phase 1 Study
Povetacicept (ALPN-303) is a dual antagonist of the BAFF (B cell activating factor) and APRIL (a proliferation inducing ligand) cytokines, which play key roles in the activation and survival of B cells, particularly antibody-secreting cells. Based upon an engineered TACI (transmembrane activator and CAML interactor) domain, povetacicept exhibits greater potency in preclinical studies versus wild-type TACI-based comparators, as well as other inhibitors of BAFF and/or APRIL alone. Povetacicept is in development for multiple B cell and/or autoantibody-related diseases.
RUBY-1 (NCT05034484) is a phase 1, randomized, placebo-controlled study in healthy adult volunteers designed to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of single doses of intravenously and subcutaneously administered povetacicept. Povetacicept was well tolerated at doses up to 960 mg, with dose-dependent pharmacokinetics and reductions in circulating immunoglobulins and antibody-secreting cells, supporting the use of a once every four-week dose regimen for subsequent studies.
