Detailed Description
PRIMARY OBJECTIVES:
I. To measure objective response rate of a combination standard of care treatment in gastroenteropancreatic neuroendocrine tumors by initiating lutetium Lu 177 dotatate within 90 days of surgical debulking.
II. To assess the radiomic profile including somatostatin receptor standardized uptake values (SSTR SUV) of large and non-large tumors in study patients)
III: To assess the safety and tolerability of peptide receptor radionuclide therapy (PRRT) post-surgical debulking in patients on study.
IV. To assess the tumor genomic profile of large, resected tumors from patients and assess for signatures of radioresistance.
OUTLINE:
Patients undergo surgical debulking on day 0 and receive lutetium Lu 177 dotatate (177Lu dotatate) intravenously (IV) over 30 to 40 minutes on day 1 of each cycle. Treatment repeats every 56 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo computed tomography (CT) scan or magnetic resonance imaging (MRI) throughout the trial, and undergo copper Cu 64 dotatate positron emission tomography/CT (dotatate PET/CT) during screening and on study.
After completion of study treatment, patients are followed up at 30-37 days after last dose and then every 3 months for 2 years.

- A woman of childbearing potential (WOCBP) - must have a negative serum or urine pregnancy test resulted within 28 days prior to initiation of first dose of lutetium Lu 177 dotatate on cycle 1, day 1; and must agree to follow instructions for using acceptable contraception from the time of signing consent, and until 7 months after her final dose of lutetium Lu 177 dotatate
- A man able to father children who is sexually active with a WOCBP must agree to follow instructions for using acceptable contraception, from the time of signing consent, and until 4 months after his final dose of lutetium Lu 177 dotatate

Measure Description |
Time Frame |
---|---|---|
Somatostatin receptor standardized uptake values (SSTR SUV)
Time Frame: Up to 2 years
|
SSTR SUV (not limited to but including measures such as SSTR SUV max, SSTR SUV mean) will be estimated for the patients undergoing post-operative research dotatate scans and compared to values from peptide receptor radionuclide therapy (PRRT) eligibility-conferring dotatate scans in these same patients.
These quantitative analytics will be performed by central review.
Changes in SSTR SUV values will be analyzed with summary statistics.
|
Up to 2 years
|
Progression-free survival
Time Frame: From the start of PRRT to the date the patient progresses radiographically or succumbs to the disease, assessed up to 2 years
|
Will be estimated by the Kaplan-Meier method.
|
From the start of PRRT to the date the patient progresses radiographically or succumbs to the disease, assessed up to 2 years
|
Overall response rate
Time Frame: Up to 2 years
|
Will be estimated by measuring the number of patients who achieve a complete response or partial response by Response Evaluation Criteria in Solid Tumors (RECIST 1.1) criteria on restaging computed tomography or magnetic resonance imaging scans =< 6 months from PRRT completion, from the total number of patients who received the study treatment and possessed measurable disease post-surgical debulking.
The number of patients who possessed measurable disease which did not meet RECIST 1.1 eligibility criteria post-surgical debulking will also be recorded.
