Humanigen Pursuing Emergency Use for COVID-19 Antibody Therapy

April 5, 2021

Humanigen said it will seek an FDA Emergency Use Authorization for its monoclonal antibody lenzilumab “as soon as possible” based on positive results from a phase 3 clinical trial that showed the drug significantly reduced the risk of death for hospitalized COVID-19 patients.

Patients in the late-stage study who received lenzilumab, along with other treatments, such as steroids and/or Gilead Sciences’ remdesivir, saw a 54 percent increase in the likelihood of survival after 28 days when compared with patients given a placebo and other treatments, the company said. The trial enrolled an estimated 520 adults across 29 clinics in the U.S. and Brazil.

Lenzilumab is meant to alleviate the symptoms of cytokine release syndrome, an immune system malfunction seen in many COVID-19 patients that can cause low oxygen levels in the lungs.
