History

Clinical trials

Three phase III clinical trials have evaluated crovalimab in both people who were C5 inhibitor–naive and those switching to crovalimab from other C5 inhibitors. COMMODORE 1 is a phase III randomized clinical trial comparing crovalimab vs eculizumab in people with paroxysmal nocturnal hemoglobinuria treated with C5 inhibitors. COMMODORE 1 examines the safety, tolerability and pharmacokinetic/pharmacodynamic properties of crovalimab in PNH patients switching from eculizumab. The study showed that crovalimab maintained disease control in PNH patients switching from eculizumab. COMMODORE 2 is a phase III randomized trial comparing crovalimab vs eculizumab in people with paroxysmal nocturnal hemoglobinuria who are naive to C5 inhibitor treatment. COMMODORE 2 was positive for its co-primary endpoints, transfusion avoidance and hemolysis control (measured lactate dehydrogenase levels) which are disease control indicators, and its data shows crovalimab is non-inferior to eculizumab. COMMODORE 3 is a phase III single-arm trial run in China, studying crovalimab in C5 inhibitor-naive people with paroxysmal nocturnal hemoglobinuria. COMMODORE 3 assessed the safety, efficacy, pharmacokinetics, and pharmacodynamics of crovalimab in people with C5-naive paroxysmal nocturnal hemoglobinuria. The study met the co-primary efficacy endpoints of haemolysis control and transfusion avoidance.
