Signet Therapeutics, a pioneering biotech company, has achieved a significant milestone with the US Food and Drug Administration (FDA)’s Investigational New Drug (IND) approval of its drug candidate, sigx1094, for the treatment of diffuse gastric cancer (DGC). This marks the introduction of the first targeted therapy for DGC, a disease currently lacking effective treatment options. Priced at a considerable investment in research and development, the approval paves the way for Phase I clinical trials aimed at assessing sigx1094’s safety and efficacy in patients with DGC and other advanced solid tumors.

Leveraging its innovative organoid disease models and a partnership with XtalPi, a leader in AI-driven drug R&D, Signet Therapeutics has significantly expedited the drug development process. Sigx1094, discovered and brought to clinical trial readiness in under four years, showcases the potential of integrating AI and organoid models to transform drug discovery and development. This approach not only speeds up the process but also enhances the accuracy of predicting patient responses, potentially increasing the success rates in clinical trials.

Signet Therapeutics’ efforts are rooted in the groundbreaking work of its founder, Dr. Haisheng Zhang, during his tenure at Dana-Farber Cancer Institute at Harvard Medical School. The research, which led to identifying four distinct molecular subtypes of gastric cancer, has been crucial in directing Signet’s focus towards DGC—a subtype known for its genomic stability but challenging treatment landscape.

Beyond DGC, sigx1094 holds promise for treating a variety of other cancers, including ovarian and pancreatic cancers. Its potential in combination therapies, especially with existing chemotherapy and targeted treatments, positions sigx1094 as a versatile candidate in oncology. Dr. Zhang’s vision for Signet is not only to fill the gaps in current treatment options but also to lead in the creation of more effective therapies through technological innovation and deep scientific understanding.

The FDA’s IND approval of sigx1094 could represent a turning point in the treatment of DGC and potentially other solid tumors. By addressing a critical unmet medical need, Signet Therapeutics could set new standards in the efficacy and safety of cancer treatments, underpinned by its innovative use of organoid models and AI.
