Roche's Actermra/Roactemra drugs reduces the likelihood patients with Covid-19 related pneumonia need mechanical ventilation, the company said on Friday.
Hospital patients taking the drug were 44% less likely to need ventilators or die, the company said, citing the results of its Empacta phase III study conducted in several countries including the United States.
Roche said it would share the results of its trial with health authorities, including the US Food and Drug Administration.
The news is a boost for Roche after an attempt to retool the rheumatoid arthritis drug Actemra/RoActemra to treat patients hospitalised with severe Covid-19 related pneumonia failed in a late-stage trial.
Its Covacta trial did not meet its primary end-point of improved clinical status in patients with Covid-19 associated pneumonia, or the key secondary end-point of reduced patient mortality, the company said in July.
"The EMPACTA trial demonstrated that Actemra/RoActemra can reduce the need for mechanical ventilation in patients with Covid-19 associated pneumonia, an important outcome in this serious disease," said Levi Garraway, Roche's chief medical officer and head of global product development.
The study is the first global phase III Covid-19 clinical trial using patients from minority racial and ethnic groups, Roche said, adding this group are often underrepresented in clinical studies and have been disproportionately affected by the ovid-19 pandemic.
The majority were Hispanic, along with significant representation from black and native American populations, the company said.
