Advanced Accelerator Applications Announces New England Journal of Medicine Publication of Lutathera® NETTER-1 Phase III Results

SAINT-GENIS-POUILLY, France, Jan. 12, 2017 (GLOBE NEWSWIRE) -- Advanced Accelerator Applications S.A. (NASDAQ:AAAP) (“AAA” or “the Company”), an international specialist in Molecular Nuclear Medicine (MNM), today announced that the New England Journal of Medicine published the results of the NETTER-1 Phase III study evaluating efficacy and safety of Lutathera® (lutetium-177 dotatate), an investigational drug, in patients with advanced, progressive somatostatin receptor-positive midgut neuroendocrine tumors (“NETs”).

In this study, the primary endpoint was progression-free survival (PFS). Secondary endpoints included objective response rate (ORR), overall survival, safety, and tolerability. The NETTER-1 study met its primary endpoint by demonstrating that treatment with Lutathera® was associated with a statistically significant and clinically meaningful 79% reduction in risk of disease progression or death versus treatment with a high dose (60 mg) of Octreotide LAR (hazard ratio 0.21, 95% Confidence Interval: 0.13-0.33; p<0.0001). The estimated PFS rate at month 20 was 65.2% (95% Confidence Interval: 50.0-76.8) in the Lutathera® arm and 10.8% (95% Confidence Interval: 3.5-23.0) in the control arm. Median PFS was 8.4 months in the control arm, and had not yet been reached in the Lutathera® arm.

Significant treatment benefits associated with Lutathera® were observed irrespective of stratification factors and prognostic factors. The response rate of 18% in the Lutathera® arm (compared to 3% with Octreotide) is also notable given that response rates above 5% have not been observed in large randomized clinical trials investigating other systemic therapies in this population. Although the trial has not reached the point at which median overall survival can be calculated, interim analysis suggests an overall survival improvement. Importantly, Lutathera® when administered concomitantly with a renal-protective agent, had low rates of grade three or four hematological toxicity, and no evidence of nephrotoxicity observed over the study time-frame (median follow-up time 14 months).

Jonathan Strosberg, MD, Associate Professor, Section Head, Neuroendocrine Tumor Program at Moffitt Cancer Center, and lead author of the publication noted, “The clinically meaningful and statistically significant improvement in PFS and ORR achieved with treatment of Lutathera®, when compared to high dose Octreotide supports its potential utility in the treatment of NET patients. As a clinician treating many patients with this condition, these results bring hope for our ability to improve lives.”

Stefano Buono, Chief Executive Officer of AAA stated, “We believe these data show significant clinical benefit of Lutathera® and are proud to have this study published in such a prestigious journal. More than 1,500 patients in the U.S. and Europe have received treatment with Lutathera® through our compassionate use and named patient programs. We believe Lutathera® can offer patients with NETs a much needed treatment option and enhance the current standard of care.”

About NETTER-1

NETTER-1 is the first Phase III multi-center, randomized, controlled trial evaluating Lutathera® in patients with inoperable, progressive, somatostatin receptor positive midgut NETs. 229 patients with Grade 1-2 metastatic midgut NETs (both functioning and not functioning) were randomized to receive Lutathera® 7.4 GBq every 8 weeks (x4 administrations), plus best supportive care (Octreotide LAR 30 mg for symptom control) versus Octreotide LAR 60 mg every 4-weeks. The primary endpoint was PFS per RECIST 1.1 criteria, with objective tumor assessment performed by an independent blinded reading center every 12 weeks. Secondary objectives included objective response rate, overall survival, toxicity, and health-related quality of life.

About Neuroendocrine Tumors (NETs)

Neuroendocrine tumors, also known as NETs, are a group of tumors originating in the neuroendocrine cells of many different organs. NETs can remain clinically silent for years delaying the diagnosis in a large number of patients. They are the second most common type of gastrointestinal malignancy by prevalence and their incidence is increasing. NETs are classified as orphan diseases by European and U.S. regulatory authorities, meaning that they affect a relatively small population of individuals in the relevant jurisdiction. In the United States, orphan drugs are defined as drugs that treat diseases or conditions that affect 200,000 or fewer individuals in the country. In the European Union, orphan drugs are defined as drugs that treat diseases or conditions that affect fewer than five out of 10,000 individuals in the European Union.

About Lutathera®

Lutathera® (or lutetium Lu 177 dotatate) is a Lu-177-labeled somatostatin analog peptide currently in development for the treatment of gastroenteropancreatic neuroendocrine tumors (GEP-NETs), including foregut, midgut, and hindgut neuroendocrine tumors in adults. Lutathera® belongs to an emerging form of treatments called Peptide Receptor Radionuclide Therapy (PRRT), which involves targeting neuroendocrine tumors with radiolabeled somatostatin analog peptides. This novel compound has received orphan drug designation from the European Medicines Agency (EMA) and the US Food and Drug Administration (FDA). Currently, Lutathera® is administered on a compassionate use and named patient basis for the treatment of NETs and other tumors over-expressing somatostatin receptors in ten European countries and in the US under an Expanded Access Program (EAP) for midgut NETs. In the analysis of the Lutathera® Phase III NETTER-1 trial’s primary endpoint of Progression Free Survival (PFS), the number of patients having disease progression or death was 23 in the Lutathera® arm and 68 in the Octreotide LAR 60 mg arm. 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% of disease progression or death versus Octreotide LAR 60 mg (hazard ratio 0.21, 95% CI: 0.13-0.33; p<0.0001).  New Drug Application and Marketing Authorization Application submissions to the FDA and EMA are currently under review.
