SHANGHAI, July 16, 2024 /PRNewswire/ -- Mabwell (688062.SH), an innovation-driven biopharmaceutical company with entire industry chain, announced that its self-developed novel B7-H3-targeting ADC (R&D code: 7MW3711) has been granted Orphan Drug Designation (ODD) by the U.S. Food and Drug Administration (FDA), for the treatment of small cell lung cancer.
The FDA grants Orphan Drug Designation to treatments for rare diseases in the United States that affect fewer than 200,000 patients. Orphan Drug Designation offers policy benefits to drug developers, including as aid with medication development, tax credits for a part of clinical trial expenditures, and seven years of market exclusivity upon approval.
7MW3711 is a novel B7-H3-targeting ADC developed by Mabwell's IDDC™ platform. It is composed of innovative antibody molecule, novel linker, and novel payload Mtoxin™ (TOP1i). When 7MW3711 enters human body, it specifically binds to antigens on the tumor cell membrane surface, be internalized and trafficked to the lysosome, release cytotoxic drug, and induce the apoptosis of tumor cells.
7MW3711 is pharmaceutical characterized as stable structure, homogeneous composition, high purity, and it is suitable for industrial scale-up. Compared with ADCs in the same class at home and abroad, 7MW3711 has shown better tumor killing effects in multiple animal tumor models. In the safety evaluation model of animals including cynomolgus monkeys, the on-target and off-target toxicities of 7MW3711 are effectively controlled, showing its good safety profile and pharmacokinetic properties. The above research results indicate that 7MW3711 has clinical differentiation characteristics and a promising future of clinical development.
About the next generation ADC platform - IDDC™
IDDC™ is a next generation ADC site-specific conjugation technology platform independently developed by Mabwell, consisting of multiple systematic core patented technologies including the site-specific conjugation process DARfinity™, the site-specific linker IDconnect™, the novel payload Mtoxin™, and the conditional release structure LysOnly™. The next generation ADCs developed based on the above systematic patented technologies have better structural uniformity, quality stability, efficacy, and tolerability. The novel payload Mtoxin™ (MF6) demonstrates good pharmacodynamics, bystander killing efficacy, and anti-multidrug resistance.
The IDDC™ platform has been validated in multiple drug candidates under development. Mabwell currently has several ADCs in clinical development stages. Among them, the novel Nectin-4-targeting ADC, 9MW2821, is in Phase III clinical trial for the indication of urothelial carcinoma. The novel B7-H3-targeting ADC, 7MW3711, and Trop-2-targeting ADC, 9MW2921, are both in clinical trial stages.
