DRP-104 can be a prodrug that broadly targets all ten glutamine-metabolizing enzymes in tumors, leading to profound anti-tumor action from its immediate effects on tumor metabolism, together with enhanced immune-mediated action because of the transforming of the tumor microenvironment.

The recently modified prodrug can take benefit of a standard property of cancer cells: a voracious appetite for an amino acid referred to as glutamine, which can be a vital making block for proteins, lipids and nucleotides, as well as for Vitality formation.

This special mechanism of motion shows assure for managing many tumor types. Dracen lately accomplished a Stage I clinical research which recognized the DRP-104 dose and routine which can be utilized Within this new mixture research with durvalumab in FLC individuals.

Quite a few early scientific tests of DON showed it absolutely was robustly efficacious in persons and mice, but its progress was halted on account of its toxicity to typical tissues, Specifically the intestine.”

Speedily developing most cancers cells use an incredible amount of glutamine, a phenomenon termed “glutamine habit,” but other healthy cells with swift turnover, like People lining the intestine, also depend upon glutamine.

The latest reports suggest that FLC tumors’ characteristic DNAJB1-PRKACA fusion brings about a metabolic rewiring of FLC cells which makes them depending on breaking down huge quantities of the amino acid glutamine. These metabolic changes “addict” FLC tumors to glutamine metabolism and cause the amplified resistance of tumor cells to killing by immune cells.

Sirpiglenastat (DRP-104) can be a wide performing glutamine antagonist. It's anticancer outcomes by instantly targeting tumor metabolism and simultaneously inducing a potent sirpiglenastat clinical trial antitumor immune reaction with immunomodulatory and antineoplastic actions.

“Our purpose was to change an previous cancer drug that experienced revealed sturdy efficacy but was far too poisonous, Specially to your gut, to get designed clinically. To do that, we utilised a prodrug technique. What is unique about our method is the fact that we used a novel chemistry structure to make a prodrug that was at the same time bio-activated in cancer cells but bio-inactivated in wholesome tissues including the gut.

The glutamine antagonist, DRP-104 (sirpiglenastat), is at the moment in clinical progress by Dracen Prescribed drugs. The mechanisms of action for DRP-104 contain a) direct inhibition of tumor mobile habit to glutamine metabolism leading to sizeable one agent action and tumor regression; b) wide metabolic reworking on the tumor microenvironment resulting in enhanced anti-tumor immune action; and c) stimulation of T effector, NK and NKT cells and inhibition of immunosuppressive MDSC and macrophage cells, perhaps leading to greater long-time period long lasting responses and survival.
