Deficiencies Found in Ascendis Pharma NDA: FDA
FDA has told Ascendis Pharma that deficiencies identified in the company’s NDA for TransCon PTH (palopegteriparatide), indicated for treating hypoparathyroidism, prevents the agency from holding further discussions about labeling and post-marketing requirements/commitments. While not disclosing any specifics, an agency letter said that its position does not currently reflect their final regulatory decision on the company’s application, Ascendis says, adding that this new issue potentially could lead to a review extension.
“The safety of patients remains our highest priority and, since our NDA submission, no new safety signals have been observed to date in our ongoing TransCon PTH Phase 2 and Phase 3 clinical trials or in our Expanded Access Program (EAP) program and these programs continue unchanged,” the company says. To date, 145 out of 154 clinical trial subjects continue to be treated with TransCon PTH in Phase 2 and Phase 3 clinical trial open label extensions.
