It’s not often that getting an NDA rejected by the U.S. FDA is cause for a company’s stock to rise. But in the case of Ascendis Pharma A/S, the agency’s anticipated complete response letter (CRL) for Transcon PTH (palopegteriparatide) offered some much-needed clarity and a potentially optimistic time frame for an NDA resubmission seeking approval of the once-daily hormone replacement therapy for hypoparathyroidism, news that sent the company’s shares (NASDAQ:ASND) up 24%, or $16.78, to close May 1 at $86.74.
A frustrating lack of detail left analysts with little to do but speculate on the odds for a 2023 U.S. FDA approval of Ascendis Pharma A/S’s Transcon PTH (palopegteriparatide), a parathyroid hormone prodrug for hypoparathyroidism, after the company disclosed a letter from the agency citing unspecified deficiencies that preclude further discussions about labeling and postmarketing requirements.
In top-line data from the Pathway phase III trial with Transcon PTH in hypoparathyroidism, Ascendis Pharma A/S provided “what many have been waiting for: a way of therapy to not only boost serum calcium into the normal range, but to make sure that the kidney issues [are] also handled,” said Aimee Shu, vice president of clinical development in endocrinology and co-director of the study, during a conference call with investors.
Phase III data are due any day from Ascendis Pharma A/S, and Wall Street’s thoughts have turned to hypoparathyroidism (HPT), an indication fraught with questions in recent years.
