Researchers are evaluating the efficacy, safety, pharmacokinetics, and immune response to BCD-236 combined with chemotherapy in women with relapsed or metastatic triple negative breast cancer (TNBC). This Phase 2 study focuses on patients who have received at least one prior systemic therapy and whose cancer has progressed or relapsed. The study aims to better understand how this combination treatment works in later lines of therapy for this aggressive breast cancer subtype. Participants will receive BCD-236 as an intravenous infusion along with chemotherapy, which will be chosen at the investigator's discretion. The study compares this combination treatment's effects and monitors participants over time. The primary outcome measured is the overall response rate at 24 weeks after starting treatment, assessing how well tumors respond to the therapy. Throughout the study, participants will undergo tumor assessments using RECIST 1.1 criteria to measure treatment response. Eligibility requires confirmation of AXL expression in tumor cells from fresh or archival tumor samples. Patients will be monitored for safety and disease progression, with evaluations including physical exams and performance status assessments. The study includes women aged 18 to 74 years with adequate health to participate and a life expectancy of at least four months.
