Mabwell Showcases Promising Results for B7-H3 ADC Therapy
Mabwell, a pioneering biopharmaceutical company, has recently shared exciting clinical research results concerning its innovative B7-H3-targeting antibody-drug conjugate (ADC), known as 7MW3711. This therapy, designed for treating advanced solid tumors, will be featured prominently at an upcoming congress, reflecting the company’s commitment to advancing cancer treatment.
Details of Clinical Study
In a phase I/II study, a total of 74 patients diagnosed with advanced solid tumors were treated with 7MW3711 as of a specific cutoff date. Notably, among the group of 54 patients receiving a dosage of 4.0 mg/kg or higher, there were significant findings, including 19 cases displaying partial or complete tumor responses. For patients with esophageal cancer treated at this dosage, the objective response rate soared to an impressive 42.9%, accompanied by a remarkable disease control rate of 100%.
When examining lung cancer patients receiving 7MW3711 at a bi-weekly dosage of 4.0 mg/kg, small cell lung cancer (SCLC) patients exhibited a 50.0% objective response rate, while the squamous non-small cell lung cancer (Sq-NSCLC) group showed a 38.5% rate. Both patient cohorts demonstrated robust disease control rates, namely 90.0% for SCLC and 92.3% for Sq-NSCLC, respectively.
Safety and Efficacy Profile
As the study progressed through the dose escalation phase, no dose-limiting toxicities (DLTs) were reported, and investigators indicated that the maximum tolerated dose (MTD) had not yet been established. Adverse events categorized as Grade ?3 were primarily related to hematological changes, including reductions in white blood cell count, neutrophil count, and other related parameters.
Understanding 7MW3711
7MW3711 is an antibody-drug conjugate with a unique mechanism targeting the B7-H3 protein prevalent in various malignant tumors. The expression and distribution characteristics of B7-H3 make this therapy particularly promising for a range of cancers, including those of the lung, sarcoma, prostate, and head and neck. The potential for 7MW3711 to address significant unmet medical needs in oncology positions it well in the treatment landscape.
This ADC is characterized by its stable chemical structure, homogeneous composition and high purity, making it suitable for large-scale production. Compared to other ADCs globally, 7MW3711 has exhibited superior tumor-killing effectiveness in various preclinical models. The technology utilized for developing this drug focuses on site-specific conjugation, resulting in a consistent drug-antibody ratio, which contributes to its overall stability and reliability across batches. The innovative payload, derived from camptothecin, demonstrates enhanced antitumor efficacy compared to traditional options utilized in similar therapies.
