Signet Therapeutics

Signet Therapeutics is a clinical-stage biotechnology company that focuses on developing targeted cancer therapies. Founded in December 2020 by Dr. Haisheng Zhang and Dr. Adam Bass, the company was established with operations in Boston, USA, and Shenzhen, China. The founding was driven by prior research at the Dana-Farber Cancer Institute at Harvard Medical School, where Dr. Zhang and a team under Dr. Bass classified gastric cancer into distinct molecular subtypes. This research highlighted the challenge of diffuse gastric cancer (DGC), a highly invasive subtype with poor response to conventional treatments.

The company's core technology integrates artificial intelligence with proprietary organoid disease models. These 3D organoid models are developed using real-world cancer genomics data to simulate drug effects in tissues that closely resemble human biology, aiming for more accurate predictions of patient responses. This approach is designed to accelerate the drug discovery process, from identifying novel targets to evaluating efficacy. Signet's business model involves developing its own pipeline of drugs while also offering its organoid platform for external collaborations with other biotech and pharmaceutical partners, which provides a consistent revenue stream.

Signet's lead drug candidate is SIGX1094, a potential first-in-class targeted therapy for diffuse gastric cancer. In collaboration with XtalPi, an AI-powered drug R&D company, Signet identified the FAK protein as a potential target for treating DGC and developed SIGX1094. The drug has received Investigational New Drug (IND) approval from the FDA in the U.S. and the NMPA in China and has entered Phase I clinical trials. The FDA has also granted SIGX1094 Orphan Drug Designation and Fast Track Designation, recognitions intended to expedite the development of treatments for serious conditions with unmet medical needs. Beyond DGC, preclinical studies suggest SIGX1094 may have potential in treating other cancers like ovarian, triple-negative breast, and pancreatic cancer. To date, Signet Therapeutics has secured nearly $31 million in funding and was named on the Forbes Asia 100 to Watch list.
