Advanced Accelerator Applications has resubmitted an NDA for Lutathera (lutetium Lu 177 dotatate) for treating unresectable or metastatic, progressive, well differentiated (G1 and G2), somatostatin receptor positive gastroenteropancreatic neuroendocrine tumors in adults. The re-filing follows a 12/2016 complete response letter that cited issues with the format, traceability, uniformity, and completeness related to certain clinical datasets, “which precluded FDA reviewers from performing the required independent analysis of these clinical studies,” the company says.

The letter also requested subgroup analyses for gender, age and racial subgroups, as well as other stratification factors and important disease characteristics, and a safety update on clinical and non-clinical studies, according to the company. “In addition, the letter noted that ‘any observations made during inspections of manufacturing facilities supporting the NDA need to be resolved prior to approval of the NDA’.”
