Study Sites Added to COMPOSE Clinical Trial of PRRT with 177Lu-Edotreotide

Additional US study sites are now participating in an ongoing clinical trial of peptide receptor radionuclide therapy (PRRT) with 177Lu-edotreotide as a first or second line of treatment in gastroenteric or pancreatic neuroendocrine tumors.

The COMPOSE trial, sponsored by ITM, is comparing the safety, efficacy and patient-reported outcomes of 177Lu-edotreotide to the standard of care for patients who have a well-differentiated and aggressive grade 2 or grade 3, somatostatin receptor-positive (SSTR+) GI NET or PNET.

Study Design

Participants in the COMPOSE clinical trial will be randomized to one of two treatment arms: experimental, targeted therapy with 177Lu-edotreotide or comparator treatment with standard of care (Everolimus, CAPTEM or FOLFOX).

Those randomized to the experimental arm will receive 6 cycles of PRRT treatment with 177Lu-edotreotide. There is a 6-week interval between the first and second treatment cycles and then 8-week intervals between subsequent cycles.

Eligibility Criteria

To be eligible for the COMPOSE trial, participants must:

  • Be 18 years of age or older
  • Have somatostatin receptor-positive disease
  • Have histologically confirmed diagnosis of unresectable, well-differentiated GET-NETs
  • Have measurable site of disease RECIST v1.1
  • Have not received prior treatment with PRRT

Other criteria will need to be met to confirm eligibility for the trial.
