A Randomized, Double-blind, Placebo-controlled, Active Comparator Phase 2/3 Study of Tucatinib in Combination With Trastuzumab, Ramucirumab, and Paclitaxel in Subjects With Previously Treated, Locally-advanced Unresectable or Metastatic HER2+ Gastric or Gastroesophageal Junction Adenocarcinoma (GEC)

In Brief

A Phase 3 clinical trial evaluating tucatinib, trastuzumab, and 4 other interventions for Gastric Adenocarcinoma and 2 related conditions. Completed, enrolled 17 participants across 48 sites in 6 countries.

Detailed Summary

This study is being done to see if tucatinib with trastuzumab, ramucirumab and paclitaxel works better than ramucirumab and paclitaxel to treat HER2-positive (HER2+) cancer of the gut (stomach or gastroesophageal cancer). This study will also look at what side effects happen when participants take this combination of drugs. A side effect is anything the drug does other than treating cancer. Study treatment will be given in 28-day cycles. In the Phase 2 part of the trial, participants and their doctors will know what drugs are being given (open-label). In the Phase 3 part, the study is "blinded." This means that participants, their doctor, and the study sponsor will not know which drugs are being given.
