Merck & Co Inc. has had a setback with its chronic cough drug gefapixant after the FDA rejected its NDA, a decision that also briefly hit the share price of rival Bellus Health Inc. before it regained market traction late Jan. 24.

Merck said the response was not related to the safety of gefapixant, a P2X3 receptor antagonist, under development for treatment of refractory chronic cough (RCC) or unexplained chronic cough in adults. Shares in Merck (NYSE:MRK) ticked down 1.4% to $78.86 while Bellus Health shares (NASDAQ:BLU) rose by 1.8% to $5.66. Read More

Once again, the U.S. FDA giveth and it taketh away. Just a few days after expanding its approval for Gilead Sciences Inc.’s Veklury (remdesivir) to provide access to more people infected with COVID-19, the FDA essentially shut down the use of two monoclonal antibody (mAb) treatments Jan. 24 that had been authorized to treat mild-to-moderate COVID-19 infections – Regeneron Inc.’s Regen-Cov (Ronapreve in Europe), an antibody cocktail of casirivimab and imdevimab, and Eli Lilly and Co.’s bamlanivimab and etesevimab that are administered together.
