BOSTON, Oct. 23, 2024 /PRNewswire/ -- HotSpot Therapeutics, Inc., a biotechnology company pioneering the discovery and development of oral, small molecule allosteric therapies targeting regulatory sites on proteins referred to as "natural hotspots," today announced it will present preclinical data from the Company's mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1) CARD11-BCL10-MALT1 (CBM) signalosome glue program highlighting its potential in NF-kB-driven solid tumors in a poster presentation at the 36^th EORTC-NCI-AACR Symposium.

MALT1 is a component of the CBM protein complex, which serves as a key regulator of NF-kB signaling in cells, including B and T cells. MALT1 is implicated in a range of hematological malignancies and solid tumors. Leveraging the Company's proprietary Smart Allostery^TM platform, HotSpot has developed a potential first-in-class small molecule signalosome glue designed to selectively inhibit the scaffolding function of MALT1, a dominant driver of the NF-kB pathway, while sparing MALT1's protease function.

"Our proprietary Smart Allostery™ platform has enabled the development of a MALT1 signalosome glue designed to selectively inhibit MALT1's scaffolding function, a distinct activity profile that enables deep inhibition of the NF-kB pathway," said Geraldine Harriman, Ph.D., Chief Scientific Officer of HotSpot Therapeutics. "As the NF-kB signaling pathway is a well-characterized oncogenic driver, these preclinical data lend support for HST-1021's potential utility for NF-kB-driven tumors, including as a precision oncology approach for solid tumors mediated by this pathway."

The presentation describes preclinical data for HST-1021, HotSpot's MALT1 CBM signalosome glue development candidate:

In contrast to MALT1 protease inhibitors, HST-1021 demonstrated robust inhibition of CBM signalosome activity.
In an NF-kB-driven nasopharyngeal carcinoma patient-derived xenograft model, HST-1021 demonstrated dose-dependent anti-tumor activity, supporting HST-1021's potential for the treatment of NF-kB-driven solid tumors.

About HotSpot Therapeutics, Inc.
HotSpot Therapeutics, Inc. is a clinical-stage biotechnology company that is pioneering a new class of allosteric drugs that target certain naturally occurring pockets on proteins called "natural hotspots." These pockets are decisive in controlling a protein's cellular function and have significant potential for new drug discovery by enabling the systematic design of potent and selective small molecules with novel pharmacology. The Company's proprietary Smart Allostery™ platform combines computational approaches and AI-driven data mining of large and diverse data sets to uncover hotspots with tailored pharmacology toolkits and bespoke chemistry to drive the rapid discovery of novel hotspot-targeted small molecules. Leveraging this approach, HotSpot is building a broad pipeline of novel allosteric therapies for the treatment of cancer and autoimmune diseases. To learn more, visit www.hotspotthera.com.
