Brief Summary:
This study will evaluate the efficacy and safety of trastuzumab deruxtecan (T-DXd) compared with ramucirumab and paclitaxel (Ram + PTX) in participants with HER2-positive gastric or gastro-esophageal junction (GEJ) adenocarcinoma who have progressed on or after a trastuzumab-containing regimen and have not received any additional systemic therapy.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Gastric Cancer, Adenocarcinoma Gastroesophageal Junction Adenocarcinoma | Drug: Trastuzumab deruxtecan Drug: Ramucirumab Drug: Paclitaxel | Phase 3 |
This study will assess the efficacy and safety of T-DXd compared with Ram + PTX in participants with HER2-positive (defined as immunohistochemistry [IHC] 3+ or IHC 2+/in situ hybridization [ISH]+) gastric or GEJ adenocarcinoma (based on [American Society of Clinical Oncology (ASCO) College of American Pathologists (CAP) guidelines who have progressed on or after a trastuzumab-containing regimen and have not received any additional systemic therapy. Participants will be randomized 1:1 to either T-DXd or Ram + PTX treatment. The primary objective will assess overall survival. Secondary objectives will further assess progression-free survival, objective response rate, duration of response, disease control rate, safety, pharmacokinetics, and immunogenicity of T-DXd.

- Objective Response Rate in Participants Who Were Administered Trastuzumab Deruxtecan Compared With Ramucirumab in Combination With Paclitaxel [ Time Frame: From start of treatment to date of documented disease progression, up to approximately 36 months ]Objective response rate (ORR) is defined as the proportion of participants who achieve a best response of complete response (CR) or partial response (PR) using the Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) criteria as assessed by Investigator.
- Duration of Response in Participants Who Were Administered Trastuzumab Deruxtecan Compared With Ramucirumab in Combination With Paclitaxel [ Time Frame: Time from initial response (CR or PR) to date of documented disease progression or death (due to any cause) whichever occurs first, up to approximately 36 months ]Duration of response (DoR) is defined time from the initial response (CR or PR) until documented tumor progression or death from any cause and based on Investigator assessment.
- Disease Control Rate in Participants Who Were Administered Trastuzumab Deruxtecan Compared With Ramucirumab in Combination With Paclitaxel [ Time Frame: From start of treatment to date of documented disease progression, up to approximately 36 months ]Disease control rate (DCR) is defined as the proportion of participants who achieved CR, PR, or stable disease (SD) for a minimum of 6 weeks during study treatment, based on Investigator assessment.
- Incidence of Treatment-emergent Adverse Events (TEAE), Serious Adverse Events (SAE), Adverse Events of Special Interest (AESI), and Physical Examination Findings [ Time Frame: From time subjects signs informed consent form up to 40 days after last study dose ]Adverse events will be graded according to the National Cancer Institute-Common Terminology Criteria for Adverse Events Version 5.0.
- Serum Concentrations for Trastuzumab Deruxtecan, total anti-HER2 antibody, and Active Metabolite MAAA-1181a [ Time Frame: Cycles 1-4 and subsequent cycles on Day 1 pre- and post-infusion (each cycle is 28 days) ]
- Percentage of Participants Who Are Anti-Drug Antibody (ADA)-Positive (Baseline and Post-Baseline) [ Time Frame: Cycles 1, 2, and 4 on Day 1 pre-infusion, then every 4 cycles on Day 1 pre-infusion, 40 day follow up until death, withdrawal of consent, or lost to follow up whichever occurs first (each cycle is 28 days) ]The immunogenicity of trastuzumab deruxtecan will be assessed.
- Percentage of Participants Who Have Treatment-emergent ADAs [ Time Frame: Cycles 1, 2, and 4 on Day 1 pre-infusion, then every 4 cycles on Day 1 pre-infusion, 40 day follow up until death, withdrawal of consent, or lost to follow up whichever occurs first (each cycle is 28 days) ]The immunogenicity of trastuzumab deruxtecan will be assessed.

Note: Prior neoadjuvant or adjuvant therapy with a trastuzumab-containing regimen can be counted as a line of therapy if the subject progressed on or within 6 months of completing neoadjuvant or adjuvant therapy. Prior neoadjuvant or adjuvant therapy that does not include trastuzumab will not be counted as a line of therapy regardless of the progression status of the subject.
- Locally or centrally confirmed HER2-positive (IHC 3+ or IHC 2+ and evidence of HER2 amplification by ISH) as classified by ASCO-CAP on a tumor biopsy obtained after progression on or after a first-line trastuzumab or approved trastuzumab biosimilar-containing regimen.

- Prior complete pneumonectomy.
