Omeros' OMS721 shows positive Phase 1 clinical trial results

Omeros announced positive clinical data in a Phase 1 clinical trial of OMS721, the company's lead human monoclonal antibody targeting mannan-binding lectin-associated serine protease-2, an important regulator of the lectin pathway of the immune system. Subcutaneous administration of OMS721 achieved a high degree of lectin pathway inhibition. The drug was well tolerated and no drug-related adverse events were observed. A Phase 2 clinical program to evaluate OMS721 in the treatment of thrombotic microangiopathies, a family of disorders that occurs in the microcirculation of the body's organs, is expected to begin enrollment in early 2014.
