Summary

The primary objectives of the study are: (1) in the dose-escalation part: to evaluate safety and tolerability and to determine the recommended Phase 2 dose (RP2D) of farletuzumab ecteribulin (MORAb-202) in participants with selected tumor types (ovarian cancer \[OC\], endometrial cancer \[EC\], non-small cell lung carcinoma \[NSCLC\], triple-negative breast cancer \[TNBC\]), and (2) in dose-confirmation part: to evaluate preliminary efficacy measured by objective response rate (ORR) of farletuzumab ecteribulin (MORAb-202) in participants with OC and EC at selected doses and to further evaluate the safety and tolerability of farletuzumab ecteribulin (MORAb-202) and (3) dose-optimization part. (divided in two parts: Part A \[OC and EC participants\] and Part B \[OC only\]): Part A: to evaluate other farletuzumab ecteribulin (MORAb-202) treatment regimens for safety, tolerability and preliminary efficacy in participants with OC and EC; to evaluate the addition of short course of oral corticosteroids following every dose of farletuzumab ecteribulin (MORAb-202) administered every 21 days; and to select treatment regimens with farletuzumab ecteribulin (MORAb-202) for further evaluation in Part B. Part B: to evaluate the safety and tolerability of different doses of farletuzumab ecteribulin (MORAb-202) as monotherapy and in combination with lenvatinib and to determine the recommended dose (RD) of farletuzumab ecteribulin (MORAb-202) as monotherapy and in combination with lenvatinib.
