Roche’s subcutaneous crovalimab given every four weeks achieves disease control in people with PNH, a life-threatening blood condition
Roche has announced successful results from the phase III COMMODORE 3 study for crovalimab, a treatment for paroxysmal nocturnal hemoglobinuria (PNH). The study met its primary endpoints, showing a 51.0% transfusion avoidance rate and 78.7% hemolysis control among participants. Crovalimab, an innovative anti-C5 recycling monoclonal antibody, is now under Priority Review for approval in China, aiming to provide critical treatment options for PNH patients where options are limited. The study included 51 patients, confirmed rapid improvements in fatigue, and had an excellent safety profile.

Basel, 11 December 2022 - Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced positive new data from the phase III COMMODORE 3 study in China, demonstrating that crovalimab, a novel anti-C5 recycling monoclonal antibody, is efficacious and well-tolerated in people with paroxysmal nocturnal haemoglobinuria (PNH). The study met its co-primary efficacy endpoints of transfusion avoidance (TA) and haemolysis control, demonstrating that participants with PNH, who have not been treated previously with complement inhibitors and who received subcutaneous crovalimab injections every four weeks, achieved disease control.1 The data were presented at the American Society of Hematology (ASH) congress, taking place from 10-13 December 2022.
PNH is an ultra-rare and life-threatening blood condition, where red blood cells are targeted and destroyed by the complement system — part of the innate immune system — causing symptoms such as anaemia, fatigue, blood clots and kidney disease. 3 C5 inhibitors — treatments that block part of the complement system — have been shown to be effective in treating the condition. Crovalimab has been engineered to be recycled into circulation, enabling sustained complement inhibition, and potentially reducing the treatment burden associated with currently available treatments. 4, 5, 6, 7 It is being investigated in a comprehensive clinical development programme, including five ongoing global phase III studies in PNH and other complement mediated diseases. 8, 9, 10, 11, 12
“We are pleased with the strength of these first phase III data for crovalimab, which we hope will address the urgent need for efficacious and well-tolerated treatment options for this life-threatening condition in China.” said Levi Garraway, M.D., Ph.D., Roche’s Chief Medical Officer and Head of Global Product Development. “As crovalimab has been developed to be taken subcutaneously and infrequently, with the option to self-administer, it has the potential to become an important treatment option for people everywhere living with paroxysmal nocturnal haemoglobinuria.”
The COMMODORE 3 study included data from 51 participants with PNH, who received crovalimab subcutaneously every four weeks during the primary study period. Results showed that the co-primary efficacy endpoints of haemolysis control and TA, indicators of disease control, were met. The mean proportion of participants with haemolysis control from week five through to week 25 was
In addition, the proportion of participants with breakthrough haemolysis (used to measure a loss of disease control) from baseline through week 25 was
Data from the COMMODORE 3 study have been submitted via China’s Centre for Drug Evaluation Breakthrough Therapy Designation pathway. This submission has been accepted under Priority Review for approval consideration in PNH by China’s National Medical Products Administration. As the availability of C5 inhibitors is extremely limited in China, there remains a high clinical need for people living with PNH there.
Data from the global crovalimab COMMODORE 1 and COMMODORE 2 PNH studies are expected in 2023. Crovalimab is being investigated as a potential treatment option for people living with PNH and other diseases such as atypical haemolytic uraemic syndrome and sickle cell disease.
About COMMODORE 3 (YO42311)
The COMMODORE 3 study is a phase III, single-arm study in China evaluating the efficacy, safety, pharmacokinetics and pharmacodynamics of crovalimab in people who have not previously been treated with complement inhibitors.8 The study included 51 participants with paroxysmal nocturnal hemoglobinuria (PNH), who received crovalimab subcutaneously every four weeks for 24 weeks. Participants enrolled in the study received a loading series of crovalimab including an intravenous dose on day one, followed by weekly crovalimab subcutaneous (SC) doses for four weeks on week one day two, then on weeks two, three, and four. Maintenance SC dosing began at week five and continued every four weeks thereafter for a total of 24 weeks of study treatment. After 24 weeks of crovalimab treatment, participants who derived benefit from the drug can continue to receive crovalimab.
About Crovalimab
Crovalimab is an investigational, novel anti-C5 recycling monoclonal antibody designed to block the complement system – a vital part of the innate immune system that acts as the body’s first line of defence against infections. Crovalimab has been engineered to address the medical needs of people living with complement-mediated diseases and overcome some of the challenges of currently available treatment options.
Similar to currently approved C5 inhibitors, crovalimab binds to C5, blocking the last step of the complement cascade. 5 However, crovalimab is also recycled into circulation, enabling rapid and sustained complement inhibition, which may potentially overcome the problem of incomplete C5 inhibition with currently available treatments.4,5,6,7 Crovalimab’s recycling action also enables low dose subcutaneous administration every four weeks, potentially removing the need for regular, time-consuming intravenous infusions. In addition, crovalimab binds to a different C5 binding site from current treatments, which has the potential to provide an effective treatment option for people with specific C5 gene mutations, who do not respond to current therapies. 5 Crovalimab is being investigated in a comprehensive clinical development programme, including five ongoing global phase III studies.8 9, 10, 11,12 Crovalimab is being evaluated in paroxysmal nocturnal haemoglobinuria, atypical haemolytic uraemic syndrome, sickle cell disease, and other complement mediated diseases.
