Study of PRRT in Metastatic, World Health Organization (WHO) Grade 1 or 2, SSTR Positive, GEP-NET Who Are Candidates for Cytoreductive Surgery

Pilot Phase 1 Study of Perioperative Peptide Receptor Radionuclide Therapy (PRRT) in Metastatic, WHO Grade 1 or 2, SSTR Positive, Gastroenteropancreatic Neuroendocrine Tumors Who Are Candidates for Cytoreductive Surgery


Sponsor

Stanford University

Enrollment

10 participants

Start Date

Mar 17, 2021

Study Type

INTERVENTIONAL

Conditions

Summary

The purpose of this study is to learn about the feasibility and safety of using Peptide Receptor Radionuclide Therapy (PRRT) before and after surgical removal of a tumor. PRRT treatment is based on the administration of a radioactive product, 177-Lu DOTA-0-Tyr3-Octreotate (Lutathera®) and its use before and after surgery is thought to increase the overall survival benefit for patients with SSTR-positive gastroenteropancreatic neuroendocrine tumors GEP-NETs.


Eligibility

Min Age: 18 Years

Inclusion Criteria9

  • Metastatic gastroenteropancreatic NET with lymph nodes or liver metastases only.
  • WHO Grade 1 or 2, Ki 67 ≤ 20% (to be confirmed at Stanford)
  • Must be a candidate for cytoreductive surgery with the goal of R1 resection as determined by a multidisciplinary tumor board discussion
  • Measurable disease as determined by RECIST v1.1
  • Confirmed presence of somatostatin receptors on all target lesions as determined by 68Ga DOTA TATE PET scan
  • Patients ≥ 18 years of age.
  • Eastern Cooperative Oncology Group (ECOG) performance status (PS) ≤ 1
  • Appropriate hematologic, liver and kidney function
  • Patients on octreotide long-acting release (LAR) at a fixed dose of 20 mg or 30 mg at 3 to 4 weeks intervals for at least 12 weeks prior to enrollment in the study

Exclusion Criteria5
