On May 30, 2026 ITM Isotope Technologies Munich SE (ITM), a leading radiopharmaceutical biotech company, reported encouraging Health-Related Quality of Life (HRQoL) data from its Phase 3 COMPETE trial in patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs). The data showed favorable and durable quality of life outcomes for patients receiving non-carrier-added (n.c.a.) ¹⁷⁷Lu-edotreotide (also known as ITM-11 or ¹⁷⁷Lu-edotreotide) compared to everolimus, a systemic standard of care treatment.

The data were presented by Jaume Capdevila, MD, PhD, study investigator and senior medical oncologist at Vall d’Hebron University Hospital, Barcelona, Spain in a poster presentation at the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting, held from May 29 – June 2, 2026 in Chicago, Illinois.

"For patients with GEP-NETs, treatment decisions are not only about preventing disease progression, but also about preserving daily functioning and quality of life," said Jaume Capdevila, MD, PhD, study investigator and senior medical oncologist at Vall d’Hebron University Hospital, Barcelona, Spain. "The COMPETE data suggest more favorable patient-reported outcomes with ¹⁷⁷Lu-edotreotide compared with everolimus, including a longer median time to deterioration in quality of life. Together with the previously reported efficacy results, these findings add important patient-centered evidence to inform treatment discussions."

The quality of life analyses included 309 patients (¹⁷⁷Lu-edotreotide, n=207; everolimus, n=102). More than 85% of patients completed the two validated EORTC QLQ questionnaires1 throughout the study: the 30-item QLQ-C30 and the 21-item QLQ-GI.NET21. Both surveys use standardized 0-100 scales to assess overall health, physical and social functioning, and GEP-NET symptom burden. Patients completed questionnaires at baseline, monthly in year one, and every three months thereafter.

Key QoL Findings:

On average, patients on the ¹⁷⁷Lu-edotreotide arm maintained their quality of life (score change: +0.9) while patients in the everolimus arm experienced a meaningful decline in quality of life (score change: -9.9)
Patients on ¹⁷⁷Lu-edotreotide experienced a longer period of time before their quality of life began to decline: a median of 10.3 months vs. 2.3 months for everolimus
A meaningful overall improvement in quality of life was reported by 43.5% of patients on ¹⁷⁷Lu-edotreotide vs. 30.4% of those on everolimus
Among those who improved, median duration of improvement was 22.0 months vs. 10.2 months, respectively
"These additional COMPETE results provide important insights into quality of life during treatment with ¹⁷⁷Lu-edotreotide, and further add to the clinical data generated to date," said Dr. Celine Wilke, chief medical officer of ITM. "Balancing treatment benefit, risk and personal preference to improve overall patient health remains a top priority for ITM, alongside delivering meaningful clinical outcomes through targeted radiopharmaceuticals."

¹⁷⁷Lu-edotreotide is an investigational product pending review by the U.S. Food and Drug Administration (FDA) and is not approved by any regulatory authority for the safety and/or efficacy of any intended use.

About the COMPETE Trial
The COMPETE trial (NCT03049189) evaluated ¹⁷⁷Lu-edotreotide (ITM-11), a proprietary, synthetic, targeted radiotherapeutic investigational agent compared to everolimus, a targeted molecular therapy, in patients with inoperable, progressive Grade 1 or Grade 2 gastroenteropancreatic neuroendocrine tumors (GEP-NETs). This trial met its primary endpoint, with ¹⁷⁷Lu-edotreotide demonstrating clinically and statistically significant improvement in progression-free survival (PFS) compared to everolimus. ¹⁷⁷Lu-edotreotide is also being evaluated in COMPOSE, a Phase 3 study in patients with well-differentiated, aggressive Grade 2 or Grade 3, somatostatin receptor (SSTR)-positive GEP-NETs.
