Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a Phase 2 evaluation of hepatic-progression free survival among patients with Grade 2 liver-dominant NET metastases undergoing combination therapy with CapTem and Y90 radioembolization.The hypothesis is to confirm safety and to assess if disease control is improved relative to expectation from either therapy alone.

A Grade 3 arm was added in 2025.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients with liver-dominant Grade 2/3 NET metastases from any primary will start CapTem and undergo simulation angiography for radioembolization planning during the first cycle. If they tolerate CapTem and are not excluded from radioembolization, then TARE will be performed on Day 7 of Cycle 2, with additional TARE of Day 7 of cycle 3 or 4 as needed to treat the entire tumor burden. Patients will remain on CapTem until progression or intolerance.

Primary outcome measure is hepatic progression-free survival.
