Despite success in other parts of the world, Opko Health Inc. and Pfizer Inc. are still struggling to gain U.S. FDA approval for the recombinant human growth hormone somatrogon in treating pediatric patients, drawing a complete response letter (CRL) with their BLA. The delay caused by the setback gives Skytrofa (lonapegsomatropin) from Ascendis Pharma A/S a chance to charge even further ahead in the pediatric market.
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. The FDA had been reviewing gefapixant since March 2021, but the regulator is now asking for additional information related to measurement of efficacy in a dreaded complete response letter. 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.
Beyondspring Pharmaceuticals Inc. said it received a complete response letter from the FDA regarding the NDA for plinabulin, the company’s lead asset. The FDA said results of a phase III registrational trial were strong enough to show benefit but a second trial is needed to satisfy the agency.

Fennec Inc. received the complete response letter (CRL) it had expected from the FDA, sidelining U.S. development of Pedmark, a formulation of sodium thiosulfate for preventing ototoxicity associated with cisplatin chemotherapy in pediatric patients older than 1 month to those 18 years of age with localized, non-metastatic, solid tumors.
Omeros Corp.’s complete response letter (CRL) from the FDA regarding its BLA for narsoplimab did not come as much of a surprise to Wall Street, but still was enough to drive shares (NASDAQ:OMER) down 26.6% to close Oct. 18 at $5.67, a loss of $2.06.
Once upon a time, Intarcia Therapeutics Inc. was a biotech unicorn valued at $3.5 billion. Its allure was its implantable Medici drug delivery system that consisted of a mini pump about the size of a matchstick. But a unicorn’s life is never completely charmed. Intarcia faced obstacles along the way – two complete response letters from the U.S. FDA and the denials of three formal dispute resolution requests. Now it looks like this story won’t have a happy ending.
An unexpected complete response letter (CRL) from the FDA has thrown a wrench into Sesen Bio Inc.’s commercial launch plans for Vicineum (oportuzumab monatox) in high-risk BCG-unresponsive non-muscle invasive bladder cancer (NMIBC). The company, which has spent the past few months completing its commercial build phase and hiring sales reps ahead of the Aug. 18 PDUFA date, instead must now address outstanding clinical and statistical data and analyses, in addition to CMC issues, cited in the CRL.
Fibrogen Inc. was braced for receiving a complete response letter (CRL) and it got one. The FDA suggested it would not approve roxadustat’s NDA for treating anemia of chronic kidney disease until more clinical work is conducted. In July, the FDA’s Cardiovascular and Renal Drugs Advisory Committee said basically the same thing as it voted 13-1 against approval for the nondialysis population and 12-2 against approval for patients on dialysis unless more trial data are submitted.
Shares of Iterum Therapeutics plc fell 40% July 26 after disclosing that the FDA issued a complete response letter (CRL) for its NDA for sulopenem etzadroxil/probenecid (oral sulopenem), an anti-infective compound, for urinary tract infections (UTIs). The agency determined the NDA cannot be approved in its present form.
