Outcome Measures

Primary Outcomes (7)

• Dose-limiting toxicity（DLT）

  DLT is defined as one of the following as per investigator related to study drug: 1. Grade ≥ 3 non-hematologic, and non-liver organ toxicities (except for Grade 3 diarrhea, nausea and vomiting in the absence of prophylactics); 2. Grade ≥ 3 cardiotoxicity, new segmental wall-motion abnormalities, or troponin I ≥ 0.2 ng/mL; 3. Left ventricular ejection fraction (LVEF) ≤ 45% and a ≥ 10% decrease from baseline; 4. Grade ≥ 4 thrombocytopenia or anemia; 5. Grade ≥ 4 t neutropenia that persists for more than 4 days or accompanied by fever \> 38.3 °C or persistent fever ≥ 38 °C for more than 1 hour; 6. Grade ≥ 3 elevation in any one of total bilirubin (TBIL), aspartate transaminase (AST) or alanine transaminase (ALT). 7. Serum transaminase \> 3 × ULN and TBIL \> 2 × ULN; 8. For Grade 2 abnormalities in AST or ALT at baseline, a measurement ≥ 10 × ULN.

  A minimum of 21 days after first dose of BAT8001

• Maximum tolerated dosed (MTD)

  The highest dose level resulting in a DLT in ≤ 1 of 6 patients was declared the MTD.

  A minimum of 21 days after first dose of BAT8001

• Area under the curve (AUC)-BAT8001(antibody-drug conjugate), total antibody and Batansine (a maytansine derivative, which is the 3AA-MDC complex)

  AUC will be evaluated and reported for BAT8001 and its metabolites.

  pre-infusion (Hour 0), 30 minutes after end of BAT8001 infusion on Day 1 Cycle 1, 2, 3, 4 (each cycle is 21 days) up to approximately 3 months

• Maximum serum drug concentration (Cmax)-BAT8001(antibody-drug conjugate), total antibody and Batansine (a maytansine derivative, which is the 3AA-MDC complex)

  Maximum serum concentration (Cmax) immediately after dosing will be evaluated and reported for BAT8001 and its metabolites.

  pre-infusion (Hour 0), 30 minutes after end of BAT8001 infusion on Day 1 Cycle 1, 2, 3, 4 (each cycle is 21 days) up to approximately 3 months

• Half-life period(t1/2)

  Half-life (t1/2) will be evaluated and reported.

  pre-infusion (Hour 0), 30 minutes after end of BAT8001 infusion on Day 1 Cycle 1, 2, 3, 4 (each cycle is 21 days) up to approximately 3 months

• Anti drug antibodies (ADA)

  Plasma level of anti drug antibodies (ADA) correlated with BAT8001 plasma level

  pre-infusion (Hour 0) on Day 1 of Cycle 1, 2, 3, 4 (each cycle is 21 days) up to approximately 3 months

• Neutralizing anti-drug antibodies (NADA)

  Neutralizing anti-drug antibodies (NADA) correlated with BAT8001

  pre-infusion (Hour 0) on Day 1 of Cycle 1, 2, 3, 4 (each cycle is 21 days) up to approximately 3 months

Secondary Outcomes (2)

• Progression free survival time(PFS)

  Baseline to the end of the study (up to 3 years)

• Overall response rate(ORR)

  Baseline to the end of the study (up to 3 years)
