AAA today announced that the U.S. Food and Drug Administration (FDA) has accepted the company’s New Drug Application (NDA) and granted Priority Review for Lutathera, a Lu-177-labeled somatostatin analogue peptide currently under development for the treatment of gastro entero pancreatic neuroendocrine tumors (GEP-NETs), including foregut, midgut, and hindgut neuroendocrine tumors in adults. The Prescription Drug User Fee Act (PDUFA) target action date is December 28, 2016.
Priority review is assigned to applications for drugs that treat serious conditions and would, if approved, provide significant improvements in the safety or effectiveness of the treatment, diagnosis or prevention of serious conditions.
The Lutathera NDA is based on the results of a randomized pivotal Phase 3 study, NETTER-1 that compared treatment using Lutathera with a double dose of Octreotide LAR in patients with inoperable midgut NETs progressive under Octreotide LAR treatment and overexpressing somatostatin receptors. The NETTER-1 study met its primary endpoint by demonstrating that treatment with Lutathera was associated with a statistically significant and clinically meaningful risk reduction of 79% in disease progression or death versus a treatment with a double dose of Octreotide LAR. Efficacy and safety data from a large Phase I-II trial conducted in more than 1,200 patients in NET indications is also part of the NDA.
“We are encouraged that the FDA has granted Priority Review for Lutathera as a potential treatment for GEP-NETs,” said Stefano Buono, Chief Executive Officer of AAA. “We believe this action emphasizes the need to improve the lives of these patients.”
