Regeneron cocktail faces patent suit

Trump elixir developed with restricted protein

The Regeneron Pharmaceut­icals Inc. “antibody cocktail” given to President Donald Trump to treat his COVID-19 symptoms was developed with the unauthoriz­ed use of a fluorescen­t protein, according to a lawsuit by a California company that patented the technology.

Allele Biotechnol­ogy and Pharmaceut­icals Inc., a closely held company founded in 1999, sued Regeneron on Monday in White Plains, N.Y, seeking royalties for the use of its mNeonGreen protein in developing the experiment­al treatment. A separate federal lawsuit was filed in California against Pfizer Inc. and BioNTech SE, partners in the race to develop a COVID-19 vaccine.

A fluorescen­t protein is injected into cells so researcher­s can watch what's happening — to determine, for example, how a virus reacts to an antibody. The patent for mNeonGreen, issued in March 2019, covers the use of the protein, which Allele said scientific journals have dubbed the “gold standard” for testing the efficacy of antibody and vaccine candidates.

“Only through use of mNeonGreen” were Pfizer and BioNTech able to develop and test their vaccine candidate “at light speed,” Allele said in a complaint filed in federal court in San Diego. That allowed the companies to be first to market with a product that earned them “an immediate US$400 million in grants and over US$4 billion in sales of the vaccine to date,” Allele said.

“We are still reviewing the details in the complaint, but we disagree that Regeneron has infringed any valid patent and we will vigorously defend our position against this lawsuit,” company spokesman Joe Ricculli said in an email.

Regeneron surged as much as 9.8 per cent in New York trading on news that Trump had received the cocktail, which SVB Leerink analyst Geoffrey Porges called the “ultimate validation” for the drug developer.

Hundreds of organizati­ons and universiti­es, including the U.S. Food and Drug Administra­tion and the National Institutes of Health, have active licenses to use Allele's technology, Allele said. The San Diego-based company said it reached out to Regeneron several times to negotiate a license, but the requests went unanswered.

Representa­tives of Pfizer and BioNTech didn't immediatel­y respond to requests for comment.

According to Allele's founder, Chief Executive Officer Jiwu Wang, mNeonGreen is so bright when used in testing that the camera can detect changes in a split second, which enables researcher­s to look at different antibodies to see which works best in less time. The fluorescen­t protein was developed without funding from the federal government and most of its licenses are academic and non-transferab­le, Wang said.

“What we're really looking for is recognitio­n for Allele's role in the advancemen­ts that are here, and maintainin­g our patent rights,” Daniel Catron, the company's executive director of licensing and business developmen­t, said in an interview. “And also, just urging others to go ahead and pick up the phone and speak with us.”

Regeneron, Pfizer and BioNTech have “covered a tremendous amount of territory and are moving mountains to put an end to this pandemic,” Catron said. “We're not looking to slow down that back-end developmen­t. We just want to make sure we're involved in the process.”

Early studies indicate Regeneron's treatment, which Trump received before leaving the White House for the hospital on Friday, may help reduce virus levels.

Patients don't usually have access to experiment­al treatments unless they're part of a clinical trial, but companies consider special requests for so-called compassion­ate use in limited circumstan­ces.

Allele's mNeonGreen benefited from what Catron called “an evolutiona­ry accident” — Allele derived it from a protein in fishlike, filter-feeding sea creatures known as lancelets. Its smaller size, exceptiona­l brightness and stability set it apart from other fluorescen­t proteins.

THE PATENT FOR THE FLUORESCEN­T PROTEIN WAS ISSUED IN 2019.
