Galmed Announces First Time Results in Oncology Studies: Aramchol Significantly Enhances Bayer's Regorafenib Effect in GI Cancer Models
- Significant enhancement of tumor-killing effect when combining Aramchol with Regorafenib in GI cancer models
- Successful preclinical results showing reduced hepatic tumor growth without normal tissue toxicities
- Phase 1b clinical trial planned for Q4 2025
- Potential to become a cost-effective first-line treatment for HCC and colorectal cancers
- Still in early research phase with only preclinical data available
- Clinical trials haven't started yet, with Phase 1b not beginning until Q4 2025
- Effectiveness in human patients remains unproven
Insights
Galmed's Aramchol shows promising synergy with Regorafenib in preclinical cancer models through enhanced autophagy mechanisms, with Phase 1b planned for late 2025.
The preclinical studies from Virginia Commonwealth University demonstrate a significant interaction between Aramchol and Regorafenib in liver and colon cancer models. This represents an interesting approach leveraging Aramchol's SCD1 inhibition properties to potentially overcome resistance to tyrosine kinase inhibitors in gastrointestinal cancers.
The underlying mechanism involves enhanced autophagy flux and autolysosome formation, with molecular changes including activation of ATM and AMPK pathways while simultaneously inactivating mTORC1 and mTORC2 pathways. This dual mechanistic approach differs from Regorafenib's action alone, potentially explaining the observed synergistic effect.
Particularly noteworthy is the observation that the combination suppressed tumor growth in hepatoma models without normal tissue toxicities, which addresses a critical concern in cancer therapeutics. The approach of targeting lipid metabolism (through SCD1 inhibition) represents an emerging strategy in oncology that could complement existing treatments.
However, these remain early-stage findings with the planned Phase 1b study not commencing until Q4 2025 at VCU's Massey Cancer Center. The translation of these preclinical results to clinical efficacy will require rigorous validation through the upcoming trials.
Galmed expands beyond metabolic disease into oncology by repurposing Aramchol, showing strategic diversification though revenue remains years away.
This announcement represents a strategic pipeline expansion for Galmed Pharmaceuticals, traditionally focused on cardiometabolic diseases. By investigating Aramchol in oncology applications, the company is leveraging its existing asset across multiple therapeutic areas, potentially maximizing the return on their research investment.
The approach of combining their compound with Bayer's already-approved Regorafenib is strategically sound. This combination strategy could accelerate the development pathway compared to novel single-agent approaches, as one component already has established safety data. The company specifically mentions positioning this as a potential "cost-effective first line treatment" for hepatocellular carcinoma (HCC) and colorectal cancers.
The company is now advancing two parallel development programs - this oncology combination approach and their recently announced Semaglutide GLP-1 sublingual development. This dual-program strategy diversifies their pipeline but will also require careful resource allocation.
The timeline indicates a Phase 1b trial planned for Q4 2025, highlighting that this remains an early-stage program with a significant development path ahead. The collaboration with Virginia Commonwealth University's Massey Cancer Center provides academic validation for this approach while potentially sharing research costs.
For Galmed, this represents both opportunity and execution challenge as they expand beyond their historical focus area into oncology therapeutics.
- Results from studies at
Virginia Commonwealth University (VCU) show that an Aramchol and Bayer's Regorafenib drug combination significantly reduced hepatic tumor growth in mice models. - The cell killing effect in-vitro and in-vivo was due to increased autophagy and death receptor signaling.
- A Phase 1b Study of the addition of Aramchol to Regorafenib in patients with advanced GI cancers is planned to be initiated at VCU's Massey Cancer Center in Q4 2025.
- Leveraging on its long-standing experience in liver and metabolic diseases, Galmed plans to advance the novel combination oncology program in parallel to the recently announced Semaglutide GLP-1 development.

Aramchol interacted with the multi-kinase inhibitors Sorafenib, Regorafenib and Lenvatinib, to kill GI tumor cells, with Regorafenib exhibiting the greatest effect. Aramchol enhanced both flux and autolysosome formation caused by Regorafenib, activating ATM and AMPK and inactivating mTORC1 and mTORC2 pathways. In addition, Regorafenib and Aramchol interacted to suppress tumor growth in hepatoma models without normal tissue toxicities.
Paul Dent, Ph.D. Professor School of Medicine Biochemistry and Molecular Biology Virginia Commonwealth University commented: "The key molecular mechanisms by which Aramchol and Regorafenib killed GI tumor cells were defined in the study. Aramchol acts to enhance autophagy through mechanisms that are different to those of Regorafenib. The interaction between Aramchol and Regorafenib, causing more autophagic flux and autolysosome formation, is required for the enhanced killing of tumor cells by the drug combination."
Allen Baharaff, President and CEO of Galmed Pharmaceuticals commented: "Targeting lipid metabolism with Aramchol, a potent SCD1 inhibitor, is a promising emerging strategy to overcome TKIs, such as Sorafenib, Regorafenib or Lenvatinib, for therapy resistance in HCC and colorectal cancers. A combination of Bayer's Regorafenib and Aramchol could potentially become a cost-effective first line treatment for HCC and other liver and colorectal cancers. The mechanisms by which the combination of Aramchol and Regorafenib kills tumor cells provide the scientific foundation for a Phase Ib clinical trial in GI tumors. We look forward to taking these findings forward in a new clinical program, alongside the recently announced Semaglutide GLP-1 sublingual development."
About Galmed Pharmaceuticals Ltd.
We are a biopharmaceutical company focused on the development of Aramchol. We have focused almost exclusively on developing Aramchol for the treatment of liver disease and we are currently seeking to advance the development of Aramchol for oncological indications outside of NASH and fibrosis. In addition, as part of our growth strategy, we are actively pursuing opportunities to expand and diversify our product pipeline specifically targeting cardiometabolic indications and other innovative product candidates that align with our core expertise in drug development.
