“Findings from the phase III NETTER-1 trial led to the January 2018 FDA approval of Lutathera (lutetium Lu 177 dotatate) for the treatment of patients with somatostatin receptor–positive gastroenteropancreatic tumors (GEP-NETs). The trial compared Lutathera with high-dose octreotide LAR for patients with 1 or 2 metastatic midgut NETs.
“In NETTER-1, patients with midgut NETs who progressed on 30 mg of octreotide were randomized to Lutathera (n = 116) or high-dose octreotide (n = 113). Patients received 4 doses of Lutathera at 7.4 GBq every 8 weeks in combination with 30 mg of octreotide. The control arm received 60 mg of octreotide LAR every 4 weeks.”
“The U.S. Food and Drug Administration today approved Lutathera (lutetium Lu 177 dotatate) for the treatment of a type of cancer that affects the pancreas or gastrointestinal tract called gastroenteropancreatic neuroendocrine tumors (GEP-NETs). This is the first time a radioactive drug, or radiopharmaceutical, has been approved for the treatment of GEP-NETs. Lutathera is indicated for adult patients with somatostatin receptor-positive GEP-NETs.”
“The FDA has accepted a resubmitted new drug application (NDA) for Lutathera (lutetium [177Lu] oxodotreotide) for the treatment of patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs). Under the Prescription Drug User Fee Act, the FDA is scheduled to make a final approval decision on or before January 26, 2018.
“The NDA is based on the phase III NETTER-1 trial, which compared Lutathera with high-dose octreotide LAR for patients with grade 1 or 2 metastatic midgut NETs. In this trial, there was a 79% reduction in the risk of progression or death with Lutathera compared with octreotide.”
“In December 2016, the FDA informed Advanced Accelerator Applications that its new drug application for Lutathera (177Lutetium DOTA-octreotate) as a treatment for patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs) would need to be resubmitted.
“The application was based on the phase III NETTER-1 trial, which randomized patients with advanced, progressive, somatostatin receptor-positive midgut NETS to receive either Lutathera (116 patients) plus best supportive care, including octreotide long-acting repeatable (LAR), or octreotide LAR alone (113 patients).”
“The FDA has issued a complete response letter (CRL) to Advanced Accelerator Applications informing the company that its new drug application for Lutathera (177Lutetium DOTA-octreotate) as a treatment for patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs) would need to be resubmitted.
“The CRL, which follows a discipline review letter (DRL) issued in November, requests new subgroup data, a safety update, and that revisions be made to the previously submitted data. The letter did not request the initiation of additional studies of Lutathera.”
“Advanced Accelerator Applications S.A. …an international specialist in Molecular Nuclear Medicine (MNM), today announced its financial results for the third quarter of 2016 and that the U.S. Food and Drug Administration (FDA) issued feedback on its New Drug Application (NDA) for Lutathera® for the treatment of gastroenteropancreatic neuroendocrine tumors (GEP-NETs) in adults.”
“Advanced Accelerator Applications S.A…, an international specialist in Molecular Nuclear Medicine (MNM), 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.”

Neuroendocrine tumors (NETs) can arise wherever neuroendocrine (hormone-producing) cells are found—which is in most organs. Most NETs (65%-70%) are gastroenteropancreatic, or GEP, arising in different gastrointestinal organs. GEP-NETs are most commonly found in the small bowel (including the appendix), stomach, and rectum. Still, NETs in general are rare, which complicates the development of new treatments and identification of the genetic drivers of these cancers. Treatment of GEP-NETs is clearly an unmet medical need, and is now even more urgent because their incidence has been on the rise in the last 20 years. Continue reading…
