Akebia's anemia drug flunked Covid study — but count the bruised biotech 'extremely encouraged'
For as long as it’s existed — since 2007 and counting — Akebia has always billed itself as a kidney disease specialist. But as it grapples with a costly FDA rejection of its lead anemia drug, the biotech is doing whatever it can to stay afloat.
And that could mean holding onto a Covid-19 program even after failing a trial.
Reporting initial findings from a study testing vadadustat, its once-rejected anemia drug, for the prevention and treatment of acute respiratory distress syndrome in patients with Covid-19 and hypoxemia, Akebia said the drug failed the primary endpoint, as measured by the National Institute of Allergy and Infectious Disease Ordinal Scale.
But, according to the biotech, the drug only missed the goal by a hair: While the primary superiority threshold over placebo was set at 95%, researchers calculated a 94% probability that their drug was better than placebo. And that means they won’t throw in the towel just yet.
“While the trial missed its prespecified primary endpoint at Day14, we are extremely encouraged by the data and believe they support further developing vadadustat as a treatment for ARDS due to COVID-19 or other causes,” CEO John Butler said in a statement. “We will now work to review the full data set more thoroughly, consult with experts in the field and ultimately consult FDA on a potential path forward.”
The trial was conducted by the University of Texas Health Science Center and partially funded by Akebia. It enrolled 449 patients.
Akebia has been grappling with a cascade of setbacks that began in March, when the FDA served up a complete response letter to its application for vadadustat in anemia due to chronic kidney disease. Regulators were concerned with safety, specifically increased risk of thromboembolic events, and asked Akebia to do another trial.
Just days after the slapdown, the agency issued a partial clinical hold on the drug’s pediatric studies, triggering a major round of layoffs. Then in May, Otsuka called off its yearslong licensing and co-development pact with Akebia, quashing hopes of earning more than $1 billion in future milestones.
Execs are now betting that revenues from their only marketed drug, Auryxia, will fund the company for the next few years while they try to turn things around by seeking European approval of vadadustat and finding a new partner.
