DRP-104 is actually a prodrug that broadly targets all ten glutamine-metabolizing enzymes in tumors, bringing about profound anti-tumor activity from its direct consequences on tumor metabolism, along with Increased immune-mediated activity because of the transforming from the tumor microenvironment.
The newly modified prodrug normally takes benefit of a standard assets of most cancers cells: a voracious hunger for an amino acid known as glutamine, and that is a critical creating block for proteins, lipids and nucleotides, in addition to for Strength development.
This one of a kind system of motion demonstrates assure for dealing with several tumor styles. Dracen recently finished a Phase I clinical study which identified the DRP-104 dose and schedule that will be used in this new mix analyze with durvalumab in FLC clients.
Considering the fact that 1947, Dana-Farber's sole focus has been to deliver qualified most cancers treatment and groundbreaking therapies for adult and pediatric people.
Speedily developing most cancers cells use an incredible quantity of glutamine, a phenomenon termed “glutamine habit,” but other wholesome cells with immediate turnover, like All those lining the gut, also trust in glutamine.
Latest experiments reveal that FLC tumors’ attribute DNAJB1-PRKACA fusion triggers a metabolic rewiring of FLC cells which makes them depending on breaking down big quantities of the amino acid glutamine. These metabolic changes “addict” FLC tumors to glutamine metabolism and produce the improved resistance of tumor cells to killing by immune cells.
Sirpiglenastat (DRP-104) is usually a wide performing glutamine antagonist. It's got anticancer effects by immediately focusing on tumor metabolism and concurrently inducing a strong antitumor immune reaction with immunomodulatory and antineoplastic activities.

Abstract Glutamine is usually a conditionally necessary amino acid eaten by rapidly proliferating most cancers cells, which deprives precisely the same fuel from immune cells and contributes to tumor immune evasion. As a result, the wide antagonism of glutamine in tumors as well as tumor microenvironment may possibly bring about immediate antitumor activity and stimulation of antitumoral immune responses. DRP-104 (sirpiglenastat) was built for a novel prodrug on the wide-acting glutamine antagonist 6-diazo-five-oxo-L-norleucine (DON). DRP-104 is undoubtedly an inactive type that is preferentially converted to DON in just tumors. Metabolomic profiling of tumors dealt with with DRP-104 exposed popular adjustments indicative of the disruption of sirpiglenastat clinical trial tumor anabolism and canonical cancer metabolism pathways; together with altered glutamine metabolism although several immunosuppressive metabolites ended up decreased. Gene expression profiling discovered wide immunological modulation, confirmed by circulation cytometry indicating that Sirpiglenastat DRP-104 procedure resulted in sizeable and wide modifications in several immune mobile infiltrates, including greater TIL, T, NK, and NK T cells. Functionally, T cells became a lot more proliferative and less exhausted; tumor-affiliated macrophages were polarized for the M1 phenotype; MDSCs and protumorigenic proteins ended up lessened in TME. Ultimately, DRP-104 demonstrated important antitumor exercise to be a monotherapy, which was more Improved in combination with checkpoint blockade therapies, resulting in improved survival and prolonged-expression strong cures. In summary, DRP-104 broadly remodels the tumor microenvironment by inducing extensive tumor metabolism effects and enhancing the infiltration and function of numerous immune cells distinct from These acquired by checkpoint inhibitor therapy.
