Mabwell Initiates First US Clinical Trial of Nectin-4 ADC in Previously Treated Triple-Negative Breast Cancer
- Mabwell has dosed the first patient in a US clinical study of Bulumtatug Fuvedotin (BFv), a novel nectin-4-targeting ADC, at Memorial Sloan Kettering Cancer Center for triple-negative breast cancer patients previously treated with ADCs.
- The multicenter trial (NCT06908928) addresses significant unmet medical needs in TNBC, where treatment options remain limited and many patients progress after topoisomerase inhibitor-based ADC therapy.
- BFv utilizes next-generation site-specific conjugation technology with MMAE payload, demonstrating superior characteristics including lower toxin release in plasma and enhanced intratumoral drug concentration.
- The drug has already received multiple FDA Fast Track designations and Orphan Drug designation, with Phase III studies ongoing in urothelial carcinoma and cervical cancer indications.
