Kevzara Fails COVID-19 Patients for the Last Time

Another attempt to repurpose an existing drug into a COVID-19 treatment has failed. In a phase 3 study with 420 severely ill COVID-19 patients, adding an anti-inflammation drug called Kevzara to standard hospital care didn’t produce any significant benefits.

In July, Actemra, an IL-6 drug from Roche (OTC: RHHBY), failed to improve patients’ clinical status or prevent their deaths.

Fortunately, a widely available option has been proven capable where pricey IL-6 treatments have failed. Dexamethasone, a decades-old steroid has been shown to reduce the risk of death by 35% for ventilated COVID-19 patients.

Regeneron isn’t pursuing Kevzara as a treatment for COVID-19 anymore, but the biotech isn’t finished addressing the pandemic. At the moment, the company is running three pivotal studies with an experimental antibody cocktail tentatively named REGN-COV2.

Regeneron developed REGN-COV2 to mimic a pair of antibodies human immune systems produce in response to SARS-CoV-2, the virus that causes COVID-19. This is an approach that worked with REGN-EB3, an antibody cocktail that significantly reduced the risk of death from the Ebola virus in 2019.
