SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), today announced that the Phase III EMPACTA study met its primary endpoint, showing that patients with COVID-19 associated pneumonia who received Actemra® (tocilizumab) plus standard of care were 44% less likely to progress to mechanical ventilation or death compared to patients who received placebo plus standard of care (log-rank p-value = 0.0348; HR [95% CI] = 0.56 [0.32, 0.97]). The cumulative proportion of patients who progressed to mechanical ventilation or death by day 28 was 12.2% in the Actemra arm versus 19.3% in the placebo arm. The EMPACTA study did not identify any new safety signals for Actemra.
“We have been striving to improve inclusion and diversity in our trials”
“The EMPACTA trial demonstrated that Actemra can reduce the need for mechanical ventilation in patients with COVID-19 pneumonia, an important outcome in this serious disease,” said Levi Garraway, M.D., Ph.D., chief medical officer and head of Global Product Development. “We plan to share this important data with the FDA and other health authorities around the world.”
The study is the first global, Phase III COVID-19 clinical trial to primarily enroll patient populations that are often underrepresented in clinical studies and have been disproportionately affected by the COVID-19 pandemic. Approximately 85% of the 389 patients were from minority racial and ethnic groups. The majority of patients were Hispanic, with significant representation of Native American and Black or African American populations. The trial was conducted in the United States, South Africa, Kenya, Brazil, Mexico and Peru.
“We have been striving to improve inclusion and diversity in our trials,” said Jamie Freedman, M.D., Ph.D., head of U.S. Medical Affairs. “During the COVID-19 pandemic, we saw how high the stakes were for many communities of color and made diversity the centerpiece of this trial.”
The EMPACTA trial builds on Genentech’s work in Advancing Inclusive Research, a cross-organizational U.S. initiative to help address barriers in clinical research for underrepresented racial and ethnic groups.
Summary of Key EMPACTA Clinical and Safety Findings
Results from the EMPACTA trial will be submitted for publication in a peer-reviewed journal.
Actemra is currently being investigated as a potential treatment for COVID-19 associated pneumonia, including in combination with an anti-viral in the Phase III REMDACTA clinical trial. Results from the Phase III COVACTA trial in patients with severe COVID-19 associated pneumonia were released in July. In addition, there are a number of independent trials of Actemra in this setting. Actemra has not been approved by any health authority for COVID-19 associated pneumonia.

About the EMPACTA Trial
EMPACTA (Evaluating Minority Patients with Actemra) is a Phase III, randomized, double-blind, placebo-controlled multicenter study (EMPACTA, NCT04372186) to evaluate the efficacy and safety of Actemra in the treatment of hospitalized COVID-19 associated pneumonia among patients that are often underrepresented in clinical trials.
The trial enrolled hospitalized patients older than 18 years with confirmed SARS-CoV-2 (COVID-19) infection with SpO2 <94% while on ambient air who did not require noninvasive or invasive mechanical ventilation. The primary endpoint is the cumulative proportion of participants dying or requiring mechanical ventilation by Day 28. Secondary objectives include: time to clinical failure, defined as the time to death, mechanical ventilation, ICU admission, or withdrawal (whichever occurs first); mortality rate by Day 28; and time to hospital discharge or “ready for discharge.”
The study enrolled 389 patients in the United States, South Africa, Kenya, Brazil, Mexico and Peru.
About the REMDACTA Trial
REMDACTA is a two-armed global Phase III, randomized, double-blind, multicenter study (REMDACTA, NCT04409262) to evaluate the efficacy and safety of Actemra plus remdesivir, versus placebo plus remdesivir in hospitalized patients with severe COVID-19 associated pneumonia receiving standard of care. The REMDACTA trial is being conducted in collaboration with Gilead Sciences, Inc. The primary endpoint of the study is clinical status as measured by a 7-Category Ordinal Scale by Day 28. Key secondary endpoints include mortality, mechanical ventilation, and intensive care variables. Patients will be followed for 60 days post-randomization.
About Actemra
Actemra was the first humanized interleukin-6 (IL-6) receptor antagonist approved for the treatment of adult patients with moderately to severely active rheumatoid arthritis (RA) who have used one or more disease-modifying antirheumatic drugs (DMARDs), such as methotrexate (MTX), that did not provide enough relief. The extensive Actemra RA IV clinical development program included five Phase III clinical studies and enrolled more than 4,000 people with RA in 41 countries. The Actemra RA subcutaneous clinical development program included two Phase III clinical studies and enrolled more than 1,800 people with RA in 33 countries. Actemra subcutaneous injection is also approved for the treatment of adult patients with giant cell arteritis (GCA) and for patients two years of age and older with active polyarticular juvenile idiopathic arthritis (PJIA) or active systemic juvenile idiopathic arthritis (SJIA). In addition, Actemra is also approved in the IV formulation for patients two years of age and older with active PJIA, SJIA or CAR T cell-induced cytokine release syndrome (CRS). Actemra is not approved for subcutaneous use in people with CRS. It is not known if Actemra is safe and effective in children with PJIA, SJIA or CRS under two years of age or in children with conditions other than PJIA, SJIA or CRS.
Actemra is intended for use under the guidance of a healthcare practitioner.
