HotSpot Therapeutics Shares Promising Results from Innovative Cancer Therapy at ESMO 2025

HotSpot Therapeutics' Promising Cancer Research Presentation at ESMO 2025



On July 4, 2025, HotSpot Therapeutics, Inc., a pioneer in biotechnology, made a notable impact at the European Society for Medical Oncology (ESMO) Gastrointestinal Cancers Congress by presenting preclinical data from its groundbreaking CBM signalosome inhibitor program. This initiative focuses on addressing the challenges of KRAS-driven colorectal cancer (CRC) and other related cancers.

Understanding the CBM Signalosome


The CBM signalosome, a crucial molecular hub, regulates several oncogenic pathways, including NFkB, JNK, mTORC1, and MYC. Its role in tumor development and survival is particularly significant in cancers driven by mutations in KRAS, a gene frequently altered in colorectal, pancreatic, and lung cancers. By targeting this signalosome, HotSpot aims to inhibit tumor growth and progress, particularly in KRAS-driven cancer cases where traditional therapies have fallen short.

HotSpot’s innovative approach is rooted in their proprietary Smart Allostery™ platform. This technology identifies regulatory sites on proteins, termed “natural hotspots,” allowing the company to develop small molecule inhibitors that specifically bind to the CBM signalosome complex. Early results from preclinical trials have exhibited dose-dependent tumor regression in various KRAS-driven models.

Key Findings from the Presentation


During the presentation at ESMO 2025, key findings highlighted the following:
  • - HotSpot's small molecule inhibitors induced significant apoptosis selectively in KRASG12 CRC cell lines, showing greater efficacy than existing KRAS, BCL2, and Bcl-xL inhibitors.
  • - In combination with a KRAS inhibitor, HotSpot’s signalosome inhibitor completely halted downstream signaling pathways in KRASG12X cell lines, indicating a robust therapeutic effect.
  • - The inhibitors demonstrated effective tumor inhibition and regression across multiple in vivo models, further supporting the potential of the CBM signalosome as a novel target in the treatment of KRAS-related cancers.

Dr. Geraldine Harriman, Chief Scientific Officer at HotSpot Therapeutics, emphasized the potential of their research: "Current KRAS inhibitors offer limited responses for most CRC patients. Our research shows that KRASG12X CRC heavily relies on the CBM signalosome for survival, positioning our inhibitors as transformative contenders in cancer therapy."

HotSpot's Commitment to Innovation


HotSpot Therapeutics continues to explore its capabilities by advancing the discovery of novel allosteric therapies aimed at treating autoimmune diseases and cancer. Their unique focus on targeting natural hotspots on proteins demonstrates significant promise for developing potent and selective therapeutic agents.

As the data from the ESMO conference circulate, HotSpot’s innovative work in targeting the CBM signalosome may very well reshape treatment strategies for patients grappling with KRAS-driven cancers.
