Novavax, Inc. (NASDAQ:NVAX) shares plummeted on Wednesday on news it faced a clinical hold on its CIC flu combination vaccine program after a serious adverse event (SAE) was reported in a Phase 2 trial participant. The SAE, motor neuropathy, surfaced in September 2024, nearly two years after the individual received the vaccine in January 2023.
Novavax (NVAX) shares plummeted nearly 20% Wednesday after the Food and Drug Administration (FDA) stopped research on the biotech firm's experimental combination COVID-19 and flu vaccine and standalone flu shot following a report of nerve damage in one patient who took the combination injection.
Novavax said the Food and Drug Administration has put a hold on its application for a combination shot targeting Covid and influenza and a standalone flu vaccine, sending shares of the company down sharply. The so-called clinical hold is due to a single report of nerve damage in a patient who received the combination shot in a phase two trial that finished in July last year.
