MORAb-202

MORAb-202 Structure Diagram

MORAb-202 is a novel investigational antibody drug conjugate (ADC) that uses a cathepsin-cleavable linker to combine investigational farletuzumab with the microtubule inhibitor payload, eribulin. Farletuzumab is a humanized antibody targeting folate receptor alpha (FRA) and has been studied in clinical trials in patients with FRA-expressing tumors. FRA expression is observed in a large number of cancers, including endometrial, gastric, non-small cell lung, ovarian and triple-negative breast, but is largely absent from normal tissue. Eribulin mesylate (Halaven®) is approved in the U.S. for the treatment of patients with metastatic breast cancer who have previously received at least two chemotherapeutic regimens for metastatic disease, including an anthracycline and a taxane in either the adjuvant or metastatic setting.

Current Clinical Studies

MORAb-202-J081-101 Phase 1 Study (Active; recruiting)

The Phase 1 trial, which is being conducted in Japan, is a first-in-human, dose-escalation study evaluating the safety and preliminary efficacy of MORAb-202 in patients with solid tumors that express folate receptor alpha (FRA). Following completion of the dose-escalation phase used to establish initial safety and optimal dosing, additional subjects will be enrolled to further study safety and preliminary efficacy of MORAb-202 in select tumor types, including triple-negative breast and endometrial cancers.
