ITM Isotope Technologies Munich SE (ITM), a leading radiopharmaceutical biotech company, today announced the presentation of the design for its second phase III trial, COMPOSE (NCT04919226) at the 19th Annual European Neuroendocrine Tumor Society (ENETS) Conference being held in a hybrid format in Barcelona on March 10-11, 2022. The study is designed to evaluate the efficacy and safety of ITM’s lead radiopharmaceutical candidate, ITM-11 (n.c.a. 177Lu-edotreotide), compared to best standard of care for patients with well‐differentiated high grade 2 and grade 3 somatostatin receptor-positive gastroenteropancreatic neuroendocrine tumors (G2+G3 SSTR+ GEP-NETs). ITM-11 is a Targeted Radionuclide Therapy consisting of the high-quality radioisotope, no-carrier-added lutetium-177 (n.c.a. 177Lu) combined with the somatostatin analogue edotreotide. The poster presentation follows the recent announcement of the first patient treated in the pivotal study.
“ITM is demonstrating its commitment to patients with neuroendocrine tumors expanding its clinical program through the COMPOSE trial with the aim of broadening therapeutic options for patients with high grade GEP-NETs. The potential role of ITM-11 in this area will enable a more personalized approach beyond chemotherapy,” said Jorge Hernando, MD, PhD, Medical Oncologist, Vall d´Hebron Institute of Oncology (VHIO), Barcelona, Spain and investigator for COMPOSE. “I am honored to be presenting ITM´s study design here in Barcelona at this year’s ENETS, the most important conference in the neuroendocrine tumors field in Europe – especially now, after two years of online meetings due to COVID-19.”
“Our aspiration with COMPOSE is to demonstrate the value of ITM-11 in more advanced GEP-NET patient populations, as we strive to provide them with better treatment options,” stated Steffen Schuster, CEO of ITM. “We value the opportunity to present our second phase III trial to the expert ENETS community as we continue advancing our lead candidate through the clinic.”
COMPOSE is an international, prospective, randomized, controlled, open-label, multi-center phase III study to evaluate the efficacy, safety, and patient-reported outcomes of first or second-line treatment with ITM-11 compared to best standard of care in patients with well-differentiated high grade 2 and grade 3 (Ki-67 index 15-55), SSTR+, GEP-NETs. The study aims to randomize 202 patients 1:1 to ITM-11 or best standard of care — either chemotherapy (CAPTEM or FOLFOX) or everolimus — according to the investigator’s choice.
The primary endpoint of the study is progression-free survival (PFS), which will be assessed every 12 weeks from randomization onwards. Secondary outcome measures include overall survival (OS) up to two years after disease progression. COMPOSE builds upon ITM’s first ongoing phase III clinical trial, COMPETE (NCT03049189), examining patients with grade 1 and grade 2, GEP-NETs. ITM’s subsidiary, ITM Solucin GmbH is the sponsor of both studies.
