Gilead Sciences said it will ask U.S. regulators to revoke the so-called “orphan drug” status it received for its experimental drug remdesivir. The status would have entitled the company to financial incentives and exclusive marketing intended for rare disease treatments.
The Food and Drug Administration granted the company's request for the designation on Monday, noting that COVID-19 qualified as a rare disease under U.S. rules, since fewer than 200,000 Americans are infected.
But experts and public advocates blasted Gilead for seeking the status.
“COVID-19 is anything but a rare disease,” stated a letter sent to the company earlier Wednesday by more than 50 consumer and patient advocacy groups. The groups noted that millions of Americans are expected to eventually be infected with the virus. As of Wednesday, cases in the U.S. topped 61,000.
Remdesivir, originally developed for Ebola, is being tested in at least five experiments. The drug interferes with viral reproduction and has shown some promise in lab and animal studies against other coronaviruses that cause similar diseases, MERS and SARS.
The drug has been given to hundreds of COVID-19 patients thus far, but rigorous studies are needed to determine if it works before it is approved.
Congress created the orphan drug program more than 35 years ago to encourage companies to develop drugs for niche diseases and conditions Since then, filing for the program has become a standard industry tactic.
Under FDA rules, manufacturers of orphan drugs receive seven years of exclusive U.S. marketing rights and tax credits on their research and development costs.
