Unmet Need
Sorafenib, a kinase inhibitor, has been the gold-standard treatment for most individuals with hepatocellular carcinoma (HCC); however, studies suggest survival after treatment remains less than 15% (Raoul et al. 2019). Additionally, side effects, including hand-foot skin reactions and diarrhea, are prevalent in almost half of patients being treated for HCC, diminishing their overall comfort (Pang et al. 2022). Therefore, there exists a need for a multi-approach therapy to more efficiently stunt tumor growth and prolong the average survival rate.
Technology Description
Researchers at Johns Hopkins have developed a technology improving upon terameprocol, a synthetic derivative of nordihydroguaiaretic acid, that has been described as an anti-cancer treatment due to its similarities with transcription factor Sp1 (Smolewski et al. 2008). Optimization via the addition of two specific moieties (poly(ethylene glycol)and nitroimidazole), the researchers developed a novel drug that seeks unique tumor-specific microenvironments during HCC development, while enhancing overall solubility, to increase overall potency.
Value Proposition
· Increased bioavailability, with new moieties causing a 6.5-11.2-fold increase in solubility
· Preferentially bioactivated in HCC regions, releasing reactive radicals to eliminate cancer cells
· Maintains IC50 in the 10-15 μM range, only two-fold greater than sorafenib (Preuss et al. 2015)
Stage of Development
· Extensive characterization has confirmed chemical structure and regional makeup of the novel cancer-targeting compound, with excellent yield rates (> 80%)
· In vitro analysis confirms growth inhibition of cell cultures
