Advanced Accelerator Applications Announces Europe

SAINT-GENIS-POUILLY, France, Sept. 29, 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 European Commission (EC) has approved the marketing authorization of lutetium ( ¹⁷⁷ Lu) oxodotreotide* (Lutathera ^® ) for “the treatment of unresectable or metastatic, progressive, well differentiated (G1 and G2), somatostatin receptor positive gastroenteropancreatic neuroendocrine tumors (GEP-NETs) in adults.” This approval allows for the marketing of lutetium ( ¹⁷⁷ Lu) oxodotreotide* (Lutathera ^® ) in all 28 European Union member states, as well as Iceland, Norway and Liechtenstein.

Stefano Buono, Chief Executive Officer of AAA, commented, “This is a historic moment. We are proud to bring this first-in-class drug, and the very first registered Peptide Receptor Radionuclide Therapy (PRRT), to the European NET patient community. We will continue to work closely with the respective health authorities to make lutetium ( ¹⁷⁷ Lu) oxodotreotide (Lutathera ^® ) widely available. We believe numerous clinical studies in the nuclear medicine field have demonstrated the advantages of selectively delivering radiation to tumor cells over certain other therapies, and we are committed to advancing this approach to cancer treatment.

“With this approval, AAA has become the first theragnostic radiopharmaceutical company in the oncology market. We believe our unique platform, which involves radiolabeling a single targeting molecule with either gallium Ga 68 for diagnostic use or lutetium Lu 177 for therapeutic use will deliver improved patient outcomes. NET patients who have had tumors successfully localized using Positron Emission Tomography (PET) scans with our SomaKit TOC™ diagnostic drug approved in Europe or our first-in-class NETSPOT ^® diagnostic drug approved in the United States, may also be candidates for therapy with lutetium ( ¹⁷⁷ Lu) oxodotreotide (Lutathera ^® ), since the drugs bind to the same receptor. This theragnostic pairing for NETs is one of three drugs in our oncology pipeline, through which we are leveraging the same targeting molecule to license two separate products. Our next pairings in development target malignancies such as prostate and breast cancers and gastrointestinal stromal tumors.”

The marketing authorization is based on results of a randomized pivotal Phase 3 study, NETTER-1 that compared treatment using lutetium ( ¹⁷⁷ Lu) oxodotreotide (Lutathera ^® ) to a double dose of Octreotide LAR in patients with inoperable midgut NETs progressive under standard dose Octreotide LAR treatment and overexpressing somatostatin receptors; as well as efficacy and safety data from a Phase 1/2 trial conducted by Erasmus Medical Center in more than 1,200 patients with a wide range of NET indications including foregut (including bronchial and pancreatic), midgut and hindgut.

The European Medicines Agency requested an update of NETTER-1 efficacy results with a cut-off date of June 30, 2016. The findings of this update were consistent with previously published results (Strosberg, et al. N Engl J Med 2017;376:125-35). The NETTER-1 study met its primary endpoint, showing a reduction of risk of progression or death of 79% using lutetium ( ¹⁷⁷ Lu) oxodotreotide (Lutathera ^® ) compared to octreotide LAR 60 mg. Although the final Overall Survival (OS) analysis (secondary endpoint) is planned for after the first of either 158 cumulative deaths, or five years after the last patient is randomized; the current update (after 71 cumulative deaths), also confirmed the favorable trend of 28 deaths in the lutetium ( ¹⁷⁷ Lu) oxodotreotide (Lutathera ^® ) arm versus 43 in the octreotide LAR 60 mg arm. The median OS in the octreotide LAR arm was 27.4 months, but was still not reached in the lutetium ( ¹⁷⁷ Lu) oxodotreotide (Lutathera ^® ) arm after 42 months, with a Hazard Ratio (HR) of 0.536, meaning a reduction of risk of death of 46% using lutetium ( ¹⁷⁷ Lu) oxodotreotide (Lutathera ^® ) compared to octreotide LAR 60 mg). ¹

Gastroenteropancreatic neuroendocrine tumors, also known as GEP-NETs, are a group of tumors originating in the neuroendocrine cells of numerous organs. According to the European Society for Medical Oncology (ESMO), the crude incidence of GEP-NETs is estimated to be 5.25/100,000 per year. ² Lutetium ( ¹⁷⁷ Lu) oxodotreotide (Lutathera ^® ) has received orphan drug designation from the European Medicines Agency.

About USAN: lutetium Lu 177 dotatate/INN: lutetium ( ¹⁷⁷ Lu) oxodotreotide (Lutathera ^® )

USAN: lutetium Lu 177 dotatate/INN: lutetium ( ¹⁷⁷ Lu) oxodotreotide (Lutathera ^® ) is an investigational ¹⁷⁷ Lu-labeled somatostatin analog peptide. USAN: lutetium Lu 177 dotatate/INN: lutetium ( ¹⁷⁷ Lu) oxodotreotide, (Lutathera ^® ) belongs to an emerging form of treatments called Peptide Receptor Radionuclide Therapy (PRRT), which involves targeting tumors with radiolabeled molecules that bind to specific receptors expressed by the tumor. This novel compound has received orphan drug designation from the European Medicines Agency (EMA) and the US Food and Drug Administration (FDA). Currently, USAN: lutetium Lu 177 dotatate/INN: lutetium ( ¹⁷⁷ Lu) oxodotreotide (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).

About Molecular Nuclear Medicine (“MNM”)

Molecular Nuclear Medicine is a medical specialty using trace amounts of active substances, called radiopharmaceuticals, to create images of organs and lesions, and to treat various diseases, like cancer. The technique works by injecting targeted radiopharmaceuticals into the patient’s body that accumulate in the organs or lesions and reveal specific biochemical processes. MNM can be divided in two branches: Molecular Nuclear Diagnostics and Molecular Nuclear Therapy. Molecular nuclear diagnostics employs a variety of imaging devices and radiopharmaceuticals. PET (Positron Emission Tomography) and SPECT (Single Photon Emission Computed Tomography) are highly sensitive imaging technologies that enable physicians to diagnose different types of cancer, cardiovascular diseases, neurological disorders and other diseases in their early stages. Molecular nuclear therapy uses radioactive sources (radionuclides) to treat a range of tumor types. Using short-range particles, this therapy can target tumors with little effect on normal tissues.
