A Combination Study of Kadcyla (Trastuzumab Emtansine) and Capecitabine in Participants With Human Epidermal Growth Factor Receptor 2 (HER2)-Positive Metastatic Breast Cancer (mBC) or HER2-Positive Locally Advanced/Metastatic Gastric Cancer (LA/mGC)

Summary

This multicenter study will assess the maximum tolerated dose (MTD) of capecitabine in combination with Kadcyla (trastuzumab emtansine) in participants with HER2-positive mBC or HER2-positive LA/mGC using a Phase 1 design, followed by a randomized, open-label Phase 2 part to explore the efficacy and safety of the combination of Kadcyla and capecitabine compared with Kadcyla alone in participants with mBC. The anticipated time on study treatment is until disease progression, intolerable toxicity, withdrawal of consent, or study end.
