Optinose Inc (OPTN)

Shares of OptiNose Inc (OPTN) dropped by 16.33% from $1.47 to $1.23 in the trading on Wednesday, December 6, 2023. The reason why OPTN is down today is due to the announcement that the U.S. Food and Drug Administration (FDA) has extended the review period for the company's supplemental new drug application (sNDA) requesting approval of XHANCE as a treatment for chronic rhinosinusitis. The new Prescription Drug User Fee Act (PDUFA) goal date for the review is March 16, 2024. The FDA's decision to extend the review period for XHANCE's sNDA has raised uncertainties and delayed potential approval. This extension likely led to concerns among investors, resulting in the notable drop in the stock price.
