简要总结
Primary Objective:
- For Cohort A, Cohort B, and Cohort C Part 2: To assess the antitumor activity of tusamitamab ravtansine in metastatic breast cancer (mBC) and tusamitamab ravtansine monotherapy and in combination with gemcitabine in metastatic pancreatic adenocarcinoma (mPAC)
- For Cohort C Part 1: Confirmation of the recommended tusamitamab ravtansine dose when administered in combination with gemcitabine
Secondary Objectives:
- To assess the safety and tolerability of tusamitamab ravtansine administered as monotherapy and in combination with gemcitabine
- To assess other efficacy parameters of tusamitamab ravtansine administered as monotherapy and in combination with gemcitabine
- To assess the immunogenicity of tusamitamab ravtansine
- To assess the pharmacokinetics (PK) of tusamitamab ravtansine and gemcitabine when given in combination
详细描述
The expected duration of study intervention for participants may vary, based on progression date and the cohort; median expected duration of study per participant is estimated at 8 months for Cohort A/C and 6 months for Cohort B (up to 1 month for screening, a median of 4 or 2 months for treatment in Cohort A/C and Cohort B respectively, a median of 1 month for EOT, and follow-up visit 90 days after the last IMP administration).

结局指标
主要结局
Objective Response Rate (ORR)
时间窗: From date of first study treatment administration (Day 1) up to maximum exposure of treatment: 26.1 weeks (Cohort A), 51.6 weeks (Cohort B), 43.3 weeks (Cohort C)
ORR was defined as the percentage of participants with a confirmed complete response (CR) or partial response (PR) as per Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1. CR was defined as disappearance of all target and non-target lesions, and normalization of tumor marker level. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to less than (\<) 10 millimeter (mm). PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters.
Cohort C (Part 1): Number of Participants With Dose Limiting Toxicities (DLTs)
时间窗: Cycle 1 (28 days)
The following adverse events (AEs) that occurred during the first cycle of treatment, unless due to disease progression or to a cause obviously unrelated to study treatment, were considered DLTs: 1. Hematological abnormalities: grade 4 neutropenia for 7 or more consecutive days, grade 3 to 4 neutropenia complicated by fever or microbiologically or radiographically documented infection, grade greater than or equal to (≥) 3 thrombocytopenia associated with clinically significant bleeding requiring clinical intervention; 2. Non-hematological abnormalities: grade 4 non-hematologic AE, grade ≥3 keratopathy. In addition, any other AE that the recruiting Investigators and Sponsor deemed to be dose limiting, regardless of its grade, was also considered as DLT.
