Edotreotide (SMT487) is a DOTA-containing somatostatin analog. Edotreotide binds with high affinity to somatostatin receptors. Somatostatin receptors are predominantly overexpressed by neuroendocrine tumors. On 15 September 2016, the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion, recommending granting a marketing authorisation for the orphan medicine edotreotide (SomaKit-TOC) intended for use in Positron Emission Tomography (PET) imaging in adult patients with gastro-enteropancreatic neuroendocrine tumours (GEP-NETs). SomaKit TOC was designated as an orphan medicinal product on 19 March 2015. 68Ga-Edotreotide, distributed under the brand name TOCscan® (Sogacin® in Austria/ France), is the companion diagnostic in ITM´s theranostic approach for the treatment of neuroendocrine tumors (NETs). N.c.a. 177Lu-Edotreotide is known as an innovative Targeted Radionuclide Therapy agent with favorable safety profile and promising efficacy. N.c.a. 177Lu-Edotreotide received an Orphan Designation as treatment of gastro-entero-pancreatic neuroendocrine tumors (GEP-NET) based on academic clinical Phase II data suggesting a significant benefit (substantially improved progression-free survival, PFS).
