Study Summary

This is the first study to be done in a newly described class of neuroendocrine tumors known as well-differentiated grade 3 neuroendocrine tumors (WD G3 NET). First described in the pancreas in 2017, the classification was broadened to include gastrointestinal tract tumors in 2019. Recent data suggest an equivalent subtype exists in the lungs (NEC with carcinoid morphology). WD G3 NETs can occur de novo as well as the result of grade progression over time. This is a single arm, multi-site, Phase II study in biomarker "unselected" participants. This study will also incorporate serial blood samples, tumor biopsies, and special imaging to better understand the impact of therapy on the tumor and microenvironment. Hyperpolarized (HP) 13C-pyruvate magnetic resonance imaging (MRI) - a novel non-radioactive imaging modality able to provide in vivo measurements of the pyruvate-to-lactate conversion rate (kpl).

Primary Outcome

ORR is defined as a complete response (CR) or a partial response (PR) according to RECIST version 1.1 criteria. The All Subjects as Treated (ASaT, ITT) population will be used for analysis which consists of all participants who received at least one dose of the study treatment. Participants without at least confirmatory scan will be classified as non-responders. The point estimate and 95% confidence interval will be reported.
