Tectonic Therapeutic Announces US IND Clearance for Lead Program, TX45 (GlobeNewswire) - "Tectonic Therapeutic...announced that the U.S. Food and Drug Administration (FDA) has cleared its Investigational New Drug (IND) application for TX45, an Fc-relaxin fusion protein being evaluated for the treatment of patients with Group 2 PH-HFpEF.....Tectonic expects to initiate the global Phase 2 clinical trial of TX45 in PH-HFpEF in the third quarter of 2024, with topline results anticipated in 2026. The trial is designed to evaluate efficacy in the broad PH-HFpEF population and enrich for the subset of Group 2 PH patients with a more severe form of disease known as combined post and precapillary pulmonary hypertension (CpcPH) defined by baseline pulmonary vascular resistance (PVR) of greater than 3 Wood units. The trial plans to enroll up to 180 subjects who will be randomized to one of two dose regimens of TX45 or placebo."
