Sponsor:

First mountain

Brief Summary:

This study will evaluate the safety and efficacy of R-DXd therapy in participants with ovarian, peritoneal, or fallopian tube cancer

Condition or disease

Solid Cancer

Intervention/treatment

Paclitaxel

Topotecan

PLD

Phase

PHASE2

PHASE3

Detailed Description:

This study will focus on R-DXd in participants with platinum-resistant, high-grade ovarian, primary peritoneal, or fallopian tube cancer. R-DXd is an antibody-drug conjugate that specifically binds to CDH6, which is overexpressed in tumor cells. The Phase 2 dose-optimization part of the study (Part A) intends to define the recommended dose based on safety and efficacy, while the Phase 3 (Part B) part of the study will compare R-DXd with Investigator's choice of chemotherapy and further evaluate efficacy.

              • * Psychological, social, familial, or geographical factors that would prevent regular follow-up.
              • * Prior or ongoing clinically relevant illness, medical condition, surgical history, physical finding, or laboratory abnormality that, in the investigator's opinion, could affect the safety of the subject; alter the absorption, distribution, metabolism, or excretion of the study drug; or confound the assessment of study results.
              • * Has a history of receiving live-attenuated vaccine (messenger RNA \[mRNA\] and replication-deficient adenoviral vaccines are not considered attenuated live vaccines) within 30 days prior to the first exposure to study intervention.
