DRP-104 is often a prodrug that broadly targets all ten glutamine-metabolizing enzymes in tumors, leading to profound anti-tumor activity from its immediate consequences on tumor metabolism, and also Increased immune-mediated activity due to the transforming in the tumor microenvironment.
The newly modified prodrug usually takes advantage of a common house of most cancers cells: a voracious urge for food for an amino acid termed glutamine, that is a essential building block for proteins, lipids and nucleotides, along with for Electricity development.
This exclusive mechanism of action exhibits promise for managing various tumor kinds. Dracen not too long ago accomplished a Stage I clinical examine which recognized the DRP-104 dose and timetable that can be utilized On this new combination research with durvalumab in FLC individuals.
Considering that 1947, Dana-Farber's sole emphasis has become to supply professional most cancers care and groundbreaking treatment options for adult and pediatric people.
Fast rising cancer cells use an amazing volume of glutamine, a phenomenon known as “glutamine dependancy,” but other healthful cells with fast turnover, like Those people lining the gut, also rely upon glutamine.
Recent scientific tests show that FLC tumors’ characteristic DNAJB1-PRKACA fusion results in a metabolic rewiring of FLC cells which makes them dependent on breaking down massive quantities of the amino acid glutamine. These metabolic modifications “addict” FLC tumors to glutamine metabolism and bring on the increased resistance of tumor cells to killing by immune cells.
Sirpiglenastat (DRP-104) is often a wide performing glutamine antagonist. It's anticancer consequences by directly targeting tumor metabolism and simultaneously inducing a potent antitumor immune response with immunomodulatory and antineoplastic routines.
“Our target was to change an outdated cancer sirpiglenastat clinical trial drug that had shown strong efficacy but was much too harmful, In particular into the intestine, to get formulated clinically. To accomplish this, we applied a prodrug tactic. What is unique about our strategy is we utilized a novel chemistry structure to produce a prodrug that was at the same time bio-activated in cancer cells but bio-inactivated in healthful tissues including the gut.
Strategy for preparing in vivo formulation: Acquire μL DMSO master liquid, future incorporate μL Corn oil, blend and clarify.
Responses to questions you will have are available within the inhibitor handling Recommendations. Subject areas consist of how to get ready inventory answers, tips on how to store inhibitors, and concerns that will need special focus for cell-based mostly assays and animal experiments.
Scientists think that FLC tumor cells may perhaps deplete glutamine from their vicinity and enrich the tumor atmosphere with immunosuppressive metabolites which includes ammonia, therefore impairing a individual’s capacity to start an effective immune reaction to the most cancers.
When planning stock methods normally make use of the batch-certain molecular bodyweight on the merchandise identified around the vial label and MSDS / COA (available on line).
This website is utilizing a protection services to safeguard alone from on-line sirpiglenastat clinical trial attacks. The action you merely performed induced the security Alternative. There are lots of steps that may bring about this block like publishing a specific term or phrase, a sirpiglenastat drp 104 SQL command or malformed info.

The glutamine antagonist, DRP-104 (sirpiglenastat), is currently in clinical development by Dracen Prescription drugs. The mechanisms of motion for DRP-104 include things like a) immediate inhibition of tumor cell dependancy to glutamine metabolism resulting in significant single agent exercise and tumor regression; b) broad metabolic remodeling from the tumor microenvironment bringing about Improved anti-tumor immune activity; and c) stimulation of T effector, NK and NKT cells and inhibition of immunosuppressive MDSC and macrophage cells, possibly bringing about bigger very long-expression strong responses and survival.
