Mabwell, an innovative biopharmaceutical company, announced that its novel Nectin-4-targeting antibody-drug conjugate (ADC), 9MW2821, has received Fast Track Designation (FTD) from the U.S. FDA for treating locally advanced or metastatic Nectin-4 positive triple-negative breast cancer (TNBC). The FDA's FTD aims to expedite the development and review of drugs for serious conditions, potentially leading to quicker market approval.
Within six months, 9MW2821 has obtained multiple FDA designations, including FTD for advanced, recurrent, or metastatic esophageal squamous cell carcinoma (ESCC) and recurrent or metastatic cervical cancer (CC) following platinum-based chemotherapy. Additionally, it received Orphan Drug Designation (ODD) for esophageal cancer (EC). These designations underscore the drug's innovative potential and its promise in treating various tumors, facilitating its accelerated development and paving the way for potential priority review.
9MW2821 is Mabwell's first site-specific conjugated Nectin-4-targeting ADC, created using their proprietary ADC platform and automated high-throughput hybridoma antibody discovery technology. It is the first Chinese-developed Nectin-4-targeting ADC to enter clinical studies and the first globally to show clinical efficacy in CC, EC, and breast cancer. The drug employs site-specific antibody modification through advanced conjugation technology, allowing it to bind specifically to Nectin-4 on tumor cell membranes. Upon binding, it is internalized, releasing a cytotoxic drug that induces tumor cell apoptosis.
9MW2821's rapid accumulation of regulatory designations highlights its therapeutic promise, aiming to provide new treatment options for patients with these challenging cancers.
