NextPoint Therapeutics Unveils T Cell Engager NPX372 Targeting B7-H7 in Solid Tumors

NextPoint Therapeutics, a cutting-edge biotechnology firm specializing in precision immuno-oncology and tumor-directed therapies, has introduced NPX372, a novel T cell engager. This development marks a significant advancement in their mission to target the B7-H7 axis in cancer treatment.

B7-H7, also referred to as HHLA2, is an emerging immunomodulatory receptor found to be upregulated in a variety of solid tumors, such as colorectal carcinoma, non-small cell lung cancer, renal cell carcinoma, and prostate cancer. Unlike other members of the B7 family, B7-H7 is primarily present on the epithelial cells of tumors, making it a unique and promising target for tumor-specific treatments.

NextPoint's approach with NPX372 is particularly noteworthy due to the challenges associated with deploying T cell engagers in solid tumors. Dr. Tatiana Novobrantseva, Chief Scientific Officer of NextPoint Therapeutics, emphasized that NPX372 has been designed to redirect T cell-mediated immunity with high specificity, potentially increasing the efficacy of monotherapy options for various solid tumors.

NPX372 is a CD3 bispecific antibody that not only engages CD3 to redirect T cell cytotoxicity towards B7-H7-positive tumors but also interacts with the B7-H7 immune axis to enhance its potency. Preclinical studies have demonstrated that NPX372 induces strong anti-tumor responses and maintains a favorable safety profile at clinically relevant doses, showing no signs of cytokine release syndrome. This antibody is a part of NextPoint’s broader immunotherapy portfolio, which aims to target multiple tumor types. The company is in the process of rapidly advancing the Investigational New Drug (IND) application for NPX372.

Ivan Cheung, CEO of NextPoint Therapeutics, highlighted NPX372 as a significant step forward in their precision immunotherapy efforts. Through their ongoing clinical programs with NPX267 and NPX887, NextPoint has developed a clinical biomarker for B7-H7 expression. This biomarker allows them to precisely identify and target patients who are most likely to benefit from treatments like NPX372. By focusing on this specific patient population, NextPoint aims to enhance the effectiveness of their therapies against solid tumors expressing B7-H7.

NextPoint Therapeutics is committed to pushing the boundaries of precision immuno-oncology by integrating foundational scientific research with clinical biomarkers to identify the most responsive patient populations for their therapies. Their innovative strategies target the B7-H7 signaling pathway and leverage its unique upregulation in cancer cells to develop tumor-specific treatments. This approach promises to deliver a new class of monotherapies tailored to the needs of cancer patients, potentially transforming their treatment outcomes.

The introduction of NPX372 underscores NextPoint’s dedication to advancing transformative treatments that can significantly improve the lives of cancer patients. By focusing on the novel B7-H7/HHLA2 axis, they are pioneering a field of precision immuno-oncology that holds great promise for developing more effective and targeted cancer therapies.
