Frequently asked questions about Safusidenib Erbumine

What is Safusidenib Erbumine?

Safusidenib Erbumine is an investigational small molecule developed by Nuvation Bio Inc. (ticker NUVB) for glioma, a type of brain tumor. It is being studied in patients with IDH1 mutated low grade glioma and has received a FAST_TRACK designation from the FDA. It remains in clinical development.

What is Safusidenib Erbumine used for?

Safusidenib Erbumine is being developed for the treatment of glioma, specifically IDH1 mutated low grade glioma. The clinical program enrolls adults 18 years and older with this biomarker-selected tumor type. It is investigational and has not been established as a marketed therapy.

What does Safusidenib Erbumine target?

Safusidenib Erbumine targets IDH1, an isocitrate dehydrogenase enzyme, and acts as an inhibitor of that target. Because the program selects patients whose gliomas carry IDH1 mutations, the drug is directed at the mutated form of the enzyme in this tumor setting.

Who makes Safusidenib Erbumine?

Safusidenib Erbumine is developed by Nuvation Bio Inc., which trades under the ticker NUVB. Nuvation Bio is the sponsor of the clinical program evaluating the drug in IDH1 mutated low grade glioma.

What phase is Safusidenib Erbumine in?

Safusidenib Erbumine is in Phase 1 development. Its single recorded trial, NCT05577416, is listed as early Phase 1 and has completed. The drug is investigational and is not described as FDA approved; it holds a FAST_TRACK designation for its development program.

What clinical trials is Safusidenib Erbumine in?

Safusidenib Erbumine has been studied in NCT05577416, titled A Study of AB-218 in Patients With IDH1 Mutated Low Grade Glioma. That early Phase 1 trial enrolled 14 patients in Australia, was uncontrolled and not randomized, and is now completed.

Is Safusidenib Erbumine the same as AB-218?

Yes. Safusidenib Erbumine is also known as AB-218, the name used in its clinical trial NCT05577416, which studied AB-218 in patients with IDH1 mutated low grade glioma. Searches for either name refer to the same investigational IDH1 inhibitor from Nuvation Bio.
