简要总结
The purpose of this study is to determine the safety, tolerability, and recommended dose of ELVN-002 in combination with trastuzumab in participants with advanced-stage HER2-positive tumors and in combination with trastuzumab, and chemotherapy in participants with advanced-stage HER2-positive colorectal cancer and breast cancer.
详细描述
Parts 1 and 3 of this study are designed to evaluate preliminary safety, tolerability, and pharmacokinetics (PK) of ELVN-002 in combination with trastuzumab in participants with advanced stage HER2 positive solid tumors. In addition, Part 3 will evaluate the preliminary efficacy of ELVN-002 in combination with trastuzumab in participants with advanced-stage HER2-positive solid tumors.
Part 2 of this study will evaluate the preliminary safety, tolerability, and PK of ELVN-002 in combination with trastuzumab and chemotherapy; capecitabine and oxaliplatin(CAPEOX) or 5-fluorouracil (5-FU), leucovorin (LCV) and oxaliplatin (mFOLFOX6) in participants with advanced stage HER2 positive colorectal cancer, or eribulin or capecitabine in participants with advanced-stage HER2-positive breast cancer, or paclitaxel in participants with advanced stage solid tumors.
In part 4, the preliminary safety, tolerability, PK, and efficacy of ELVN-002 in combination with trastuzumab and CAPEOX or mFOLFOX6 will be evaluated in participants with HER2-positive colorectal cancer.

结局指标
主要结局
Incidence of adverse events (AEs)
时间窗: 24 months
AEs will be used to support that the recommended doses for expansion are likely to be tolerable
Incidence of laboratory abnormalities
时间窗: 24 months
Clinically significant laboratory abnormalities will be used to support that the recommended doses for expansion are likely to be tolerable
Incidence of dose limiting toxicities (DLTs; Phase 1a only)
时间窗: 21 days
DLTs will be used to support that the recommended doses for expansion are \</= maximum tolerated dose (MTD)
Incidence of electrocardiogram abnormalities
时间窗: 24 months
Clinically significant electrocardiogram abnormalities will be used to support that the recommended doses for expansion are likely to be tolerable
