Regeneron stopped development of antibody to RSV

| By | Clinical Trials, Drug Development

Regeneron Pharmaceuticals, a leading biotechnology company, announced that a Phase 3 study evaluating suptavumab, an antibody to respiratory syncytial virus (RSV), did not meet its primary endpoint of preventing medically-attended RSV infections in infants.

Suptavumab did show signs of efficacy in a subgroup of patients. Adverse events were generally balanced between suptavumab and placebo. Regeneron plans to discontinue further clinical development of this antibody.

“We are disappointed in these results, as we had hoped suptavumab might offer a new option for the thousands of infants impacted by serious RSV infections every year,” said George D. Yancopoulos, M.D., Ph.D., President and Chief Scientific Officer of Regeneron. “Regeneron has a robust pipeline across many serious diseases, and we look forward to important data readouts from other programs in the coming weeks and months.”
