Receiving a second complete response letter (CRL) from the U.S. FDA for gefapixant to treat refractory and unexplained chronic cough – an indication for which there are no approved treatments in the U.S., Merck & Co. Inc. said it is reviewing the agency’s feedback to determine the next steps, if any, for the oral selective P2X3 receptor antagonist.
Low expectations on Wall Street for the Pulmonary-Allergy Drugs Advisory Committee (PADAC) sit-down on Merck & Co. Inc.’s P2X3 receptor antagonist gefapixant for chronic cough (CC) translated to negative balloting by panelists.

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.
