BERLIN--(BUSINESS WIRE)-- Bayer announced today the start of a Phase II clinical trial (SIRIUS study) with BAY3018250, an investigational first-in-class anti-alpha2 antiplasmin (anti-α2ap) antibody in patients with deep vein thrombosis (DVT). The results of this study might provide evidence of anti-α2ap antibody’s potential as a treatment option in indications of high medical relevance.

“We are excited to advance our anti-α2ap antibody to the next stage of clinical development in patients with deep vein thrombosis,” said Christian Rommel, Member of the Executive Committee of Bayer AG’s Pharmaceuticals Division and Head of Research and Development. “This study will also help to better understand if the anti-α2ap antibody is suitable as a thrombolytic to treat patient in indications of high medical relevance. By targeting alpha2 antiplasmin, we will have a more precise approach to modulate plasmin to break down thrombotic blood clots.”

Following the successful first-in-human trial, the goal of the randomized, double-blind, placebo-controlled, multi-center Phase II study (SIRIUS study) is to assess the efficacy and safety of BAY3018250 in patients with symptomatic proximal deep vein thrombosis. BAY3018250 is designed to target alpha2 antiplasmin. α2ap’s primary function is to inhibit the enzymatic activity of plasmin and thereby balance the formation and dissolution of blood clots.
