Metastatic Malignant Neoplasm in the Liver Clinical Trial
Official title:
Surgical Debulking Prior to Peptide Receptor Radionuclide Therapy (PRRT) in Patients With Well Differentiated Gastroenteropancreatic Neuroendocrine Tumors
This phase IV trial evaluates how well giving standard of care (SOC) peptide receptor radionuclide therapy (PRRT) after SOC surgical removal of as much tumor as possible (debulking surgery) works in treating patients with grade 1 or 2, somatostatin receptor (SSTR) positive, gastroenteropancreatic neuroendocrine tumors (GEP-NETs) that have spread from where they first started (primary site) to the liver (hepatic metastasis). Lutetium Lu 177 dotatate is a radioactive drug that uses targeted radiation to kill tumor cells. Lutetium Lu 177 dotatate includes a radioactive form (an isotope) of the element called lutetium. This radioactive isotope (Lu-177) is attached to a molecule called dotatate. On the surface of GEP-NET tumor cells, a receptor called a somatostatin receptor binds to dotatate. When this binding occurs, the lutetium Lu 177 dotatate drug then enters somatostatin receptor-positive tumor cells, and radiation emitted by Lu-177 helps kill the cells. Giving lutetium Lu 177 dotatate after surgical debulking may better treat patients with grade 1/2 GEP-NETs

Primary | Somatostatin receptor standardized uptake values (SSTR SUV) | 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 | |
Primary | Progression-free survival | 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 | |
Primary | Overall response rate | 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. | Up to 2 years | |
Primary | Overall survival | 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 | |
Primary | Incidence of adverse events | Toxicity will be estimated by documenting the grade 3/4 adverse events, according to Common Terminology Criteria for Adverse Events version 5.0, experienced by study patients. | Up to 2 years | |
Primary | Gene mutations | Mutations in genes associated with radioresistance (defined from other malignancies) and other mutations in large resected neuroendocrine tumors will be recorded. Mutations will be described descriptively. | Up to 2 years |
