Roche (SIX: RO, ROG; OTCQX: RHHBY) announced the initiation of a global phase III, randomised, double-blind, multicentre study (REMDACTA) to evaluate the safety and efficacy of Actemra/RoActemra plus the investigational antiviral remdesivir, versus placebo plus remdesivir in hospitalised patients with severe COVID-19 pneumonia, in collaboration with Gilead Sciences, Inc.
REMDACTA is a two-armed global phase III, randomised, double-blind, multicentre study to evaluate the efficacy and safety of Actemra/RoActemra plus remdesivir, versus placebo plus remdesivir in hospitalised patients with severe COVID-19 pneumonia receiving standard of care (SOC). The primary and secondary endpoints include clinical status, mortality, mechanical ventilation, and intensive care variables. Patients will be followed for 60 days post-randomisation.
COVACTA is a double-blind, placebo-controlled phase III study (COVACTA, NCT04320615) evaluating the safety and efficacy of intravenous Actemra/RoActemra added to standard of care in approximately 450 adult patients hospitalised with severe COVID-19 pneumonia compared to placebo plus standard of care. The primary endpoint is clinical status assessed using a 7-Category Ordinal Scale at day 28. The ordinal scale ranges from one (discharged from hospital) to seven (death), and covers different hospital locations such as non-intensive care unit (non-ICU) or ICU, and ventilation/treatment requirements, including not requiring supplemental oxygen, or requiring extracorporeal membrane oxygenation (ECMO) or mechanical ventilation and additional organ support. Key secondary endpoints include mortality, mechanical ventilation, clinical status at day 14, time to clinical improvement, and time to discharge.
Actemra/RoActemra was the first approved anti-IL-6 receptor biologic available in both intravenous (IV) and subcutaneous (SC) formulations for the treatment of adult patients with moderate-to-severe active rheumatoid arthritis (RA). Actemra/RoActemra can be used alone or with methotrexate (MTX) in adult RA patients who are intolerant to, or have failed to respond to, other disease-modifying anti-rheumatic drugs (DMARDs). In Europe, RoActemra IV and SC are also approved for use in adult patients with severe, active and progressive RA who previously have not been treated with MTX. Actemra/RoActemra IV and SC are approved globally for polyarticular juvenile idiopathic arthritis (pJIA) and in the US and Europe for systemic juvenile idiopathic arthritis (sJIA) in children two years of age and older. Actemra/RoActemra SC injection is also the first approved therapy for the treatment of giant cell arteritis (GCA) in more than 40 countries, including the US and Europe. In the US and Europe, Actemra/RoActemra IV injection is approved for the treatment of chimeric antigen receptor (CAR) T-cell-induced severe or life-threatening cytokine release syndrome (CRS) in people two years of age and older. Actemra/RoActemra was the first approved treatment for CRS in this setting. A prefilled autoinjector ACTPen has been approved in the US and Europe. In Japan, Actemra is also approved for the treatment of Castleman’s Disease, adult Still's disease and Takayasu Arteritis. Actemra/RoActemra is part of a co-development agreement with Chugai Pharmaceutical Co., Ltd and has been approved in Japan since April 2005. Actemra/RoActemra is approved in more than 110 countries worldwide.
