About this trial

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.
