Pusch S, Krausert S, Fischer V, Balss J, Ott M, Schrimpf D, et al. This is especially important to recognize because DS may occur earlier than best response, which in some cases is a CR between 4 and 6 months on therapy. (2017) 130:722–31. Isocitrate Dehydrogenase (IDH) is an enzyme that involves the conversion of isocitrate to α-ketoglutarate in tricarboxylic acid cycle. Ivosidenib or enasidenib combined with standard induction chemotherapy is well tolerated and active in patients with newly diagnosed AML with an IDH1 or IDH2 mutation: initial results from a Phase 1 trial. AGI-6780 is a urea sulfonamide inhibitor of the IDH2R140Q mutant enzyme specifically and exhibits non-competitive inhibition with respect to substrate, and uncompetitive inhibition with respect to the NADPH cofactor, operating at an allosteric site at the enzyme's dimer interface (Figure 2) (72, 73). doi: 10.1016/j.ccr.2010.01.020, 19. MutIDH2 inhibitors: Enasidenib (AG-221), AGI-6780. IDH mutations occur very early in tumorigenesis and the resultant buildup of the oncometabolite 2-hydroxyglutarate leads to a variety of alterations in histone and DNA methylation that drive the development of gliomas and other tumors.41 The US Food and Drug Administration recently approved enasidenib, a mutant IDH2 inhibitor, for the treatment of relapsed or refractory acute myelogenous leukemia.42 Inhibitors of mutant IDH1 and IDH2 are of interest in low-grade gliomas as well, and clinical trials are ongoing. The rates of formation and dissociation of the enzyme inhibitor … Mutations in IDH1 and IDH2 are seen in over 80% of lower-grade gliomas (WHO grades II and III) and secondary GBMs that are thought to later develop from lower-grade lesions (2, 32, 33). using AGI-5198 in an inducible mutIDH1 knock-in human astrocyte model by Johannessen et al. Impact Factor 4.848 | CiteScore 3.5More on impact ›, University of Louisiana at Lafayette, United States, University of California, San Francisco, United States. Isocitrate dehydrogenase 1 (IDH1), which catalyzes the conversion of isocitrate to α-ketoglutarate, is one of key enzymes in the tricarboxylic acid cycle (TCA). Cancer Cell. This life-threatening syndrome is typically seen within 3 weeks of ATRA treatment initiation and consists primarily of fever and respiratory distress, with other notable findings including weight gain, lower extremity edema, pleural or pericardial effusions, and episodic hypotension. Marcucci G, Maharry K, Wu YZ, Radmacher MD, Mrózek K, Margeson D, et al. Clinical trials in AML/hematologic malignancies. However, evidence supporting combination therapy involving DNMT inhibitors and mutIDH inhibitors in glioma remains limited to early and mixed evidence from preclinical data alone (121, 123). Arsenic trioxide: safety issues and their management. By continuing you agree to the use of cookies. (2015) 90:732–6. (2018) 559:125–9. Montesinos P, Sanz MA. The Global Isocitrate Dehydrogenase Inhibitors Market is anticipated to expand at a CAGR of around XX% during the forecast period, 2020–2026. Preliminary results of another phase 1b/2 study looking at Ivosidenib with subcutaneous azacitidine in newly diagnosed AML were presented at the 2018 ASCO Annual Meeting; of 23 patients taking both Ivosidenib and azacitidine, 18 (78%) received a response, of whom 10 had complete remission and the median time to response was 1.8 months (ClinicalTrials.gov NCT02677922) (94). Michael R. Grunwald, Mark J. Levis, in Seminars in Hematology, 2015, Many other targets and targeted therapies are being evaluated in AML. AG-881 (Vorasidenib), a pan-inhibitor, is the only other mutIDH inhibitor currently with supporting clinical data in glioma. RNA methylation patterns have also been shown to be critical for glioblastoma stem cell self-renewal and tumorigenesis specifically, and as previously discussed, the early molecular insults of IDH mutations and 2HG include competitive inhibition of histone demethylases (22, 23, 124, 125). Ornithine decarboxylase (ODC) catalyzes the initiation of de novo polyamine synthesis and is frequently upregulated in cancer as a consequence of events such as Myc activation,186 ultraviolet (UV) radiation exposure,187 and methylthioadenosine phosphorylase (MTAP) deletion.188 This increase in ODC activity provides an abundant polyamine pool for cell proliferation,189 and promotes signal transduction by the activation of MAP kinases.190 An FDA-approved ODC inhibitor, difluoromethylornithine (DFMO, or eflornithine), has been shown to effectively reduce polyamine levels, ultimately resulting in reduced tumor vascularity191 and metastasis192 in transgenic murine models.
