isocitrate dehydrogenase inhibitor

Indirect hyperbilirubinemia was presumed to be the result of a benign, Gilbert syndrome—like mechanism, as no evidence was found in these patients of Enasidenib-induced hepatotoxicity. doi: 10.1016/j.jnci.2012.10.004, 114. 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. The first mutIDH2-specific inhibitor to come out of development was AGI-6780, developed as part of the Celgene/Agios collaboration (72). The European APL Group. Abstract Background: R132H mutation of isocitrate dehydrogenase 1 (IDH1) is found in ~75% of low-grade gliomas and secondary glioblastomas as well as in several other types of cancer. Pan-inhibitors: AG-881. Shortly after the approval of Enasidenib, its mutIDH1 counterpart, Ivosidenib, similarly demonstrated safety and clinical efficacy in a phase 1/2 dose-escalation/dose-expansion trial of relapsed/refractory IDH1-mutant AML (ClinicalTrials.gov NCT02074839) (13). MutIDH inhibitors have demonstrated some efficacy in IDH-mutant AML and early results have validated their safety in glioma patients. Together, these findings suggest that despite the possibility of conversion of mutIDH from “driver” to “passenger” in supporting some chromatin modifications and cellular growth, other biological pressures for 2HG production persist over time in IDH-mutant cancers (80, 99). Blood. (2011) 118:4561–6. Nat Chem Biol. Ivosidenib (IDH1 inhibitor) and enasidenib (IDH-2 inhibitor) are specific IDH inhibitors that can be considered for patients with myeloid neoplasms with RS and concomitant IDH1mt or IDH2mt, which co-occur at a frequency of 2% to 5%.14,84–86 Because of the relative genetic heterogeneity in myeloid neoplasms, future therapies should look at targeting novel pathways instead of inhibition of single mutant genes. Lu R, Wang GG. (2016) 16:1344–58. Reported adverse events in trials for solid tumors are fewer and far more manageable: In the phase 1 studies for AG-881, the most common adverse events included fatigue (30.8–38.7%), nausea (26.9–35.5%), and dose-dependent transaminase elevation (without elevated bilirubin) (34.4–44.2%) (69, 98). DNMT3A and IDH mutations in acute myeloid leukemia and other myeloid malignancies: associations with prognosis and potential treatment strategies. Emerging insights into the molecular and cellular basis of glioblastoma. Furthermore, preclinical evidence that Ivosidenib modulates oncogenic properties of cancer cells (in addition to 2HG reduction) has been repeatedly demonstrated by induction of cellular differentiation in AML myeloblasts and through inhibition of cellular migration and invasion in a chondrosarcoma cell line (88–90). A key study by Johannessen et al. 9.7). Hartmann C, Meyer J, Balss J, Capper D, Mueller W, Christians A, et al. Ungerstedt JS. Enasidenib was dosed at 100 mg orally daily in the expansion phase of trial. R-2HG competitively inhibits alpha-ketoglutarate–dependent enzymes leading to DNA and histone hypermethylation, chromatin modification, and differentiation arrest of hematopoietic cells. doi: 10.1007/s40265-018-0978-3, 11. 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). J Inorg Biochem. Crystal structures of pan-IDH inhibitor AG-881 in complex with mutant human IDH1 and IDH2. Given that 10% to 25% of pediatric AML is cytogenetically normal [32,87], further research is warranted to test the utility of IDH1/2 inhibition in specific subgroups of pediatric patients that harbor mutations. IDH1 mutational clearance was observed in 21% of patients who achieved a CR or CRi. (2018) 4:1106–10. IDH1 and IDH2 gene mutations identify novel molecular subsets within de novo cytogenetically normal acute myeloid leukemia: a Cancer and Leukemia Group B study. Popovici-Muller J, Saunders JO, Salituro FG, Travins JM, Yan S, Zhao F, et al. A precursor form of Enasidenib was originally selected from a high-throughput screen for inhibitors of the most prevalent form of mutIDH2 in AML, IDH2R140Q (47, 51). Optimization of a lead compound based on differential inhibition of mutIDH1 and wild-type IDH1 enzymes resulted in BAY-1436032, an allosteric inhibitor that binds at the IDH dimer interface (Figure 2) (63). (2018) 20:608–20. (2017) 8:1116–21. IDH305 has moved into clinical testing in humans with IDH-mutant glioma, AML/MDS, and other solid tumors, and phase 1 safety data in all tumor types is promising (ClinicalTrials.gov NCT02381886) (83). (2010) 119:487–94. doi: 10.1126/science.1164382, 3. This is in stark contrast to glioma, where the majority of IDH mutations are in IDH1. Kim ES. Cancer Discov. Blood. N Engl J Med. IDH1 is found in the cytosol and in peroxisomes, while IDH2 is a mitochondrial enzyme. Molecular pathogenesis and targeted therapies for intrahepatic cholangiocarcinoma. (2010) 116:2779–82. published the results of a landmark study in which they sought to pinpoint recurrent mutations in AML that may be associated with the pathogenesis of the malignancy (43). Am J Hematol. Throughout the study period, Ivosidenib has continued to demonstrate good oral bioavailability, a lengthy half-life (mean 40–102 h after a single dose), and a persistent, robust response in 2HG depletion in both plasma and tumor tissue (97). However, the current paradigms of treatment are changing through a better understanding of the disease genetics and pathophysiology. ACTR-31. doi: 10.1158/1535-7163.TARG-15-PL04-05, 96. doi: 10.1056/NEJMoa0808710, PubMed Abstract | CrossRef Full Text | Google Scholar, 2. Ivosidenib, a small-molecule inhibitor of IDH1, was investigated in a single-arm phase 1 dose-escalation and dose-expansion study for IDH1-mutated hematologic cancers.38 The R/R AML cohort included 179 patients aged ≥ 18 years, with an ECOG performance status of 0 to 2 and documented IDH1-mutated AML who received ivosidenib at 500 mg once daily in 28-day cycles. Early results from ongoing phase 1 safety and dose-escalation trials continue to be updated annually during national conferences (69, 95–100). At a median follow up of 7.7 months, median OS in R/R AML patients was 9.3 months (95% CI, 8.2–10.9). AG-881 has also been shown to effectively penetrate the blood-brain barrier in rodents, implicating its potential to treat both IDH-mutant AML and glioma patients (62). CR/CRh rates were similar in patients with either R140 or R172 mutations, despite the drug's reduced affinity for IDH2-R172. One extreme of this is IDH-DS, an outcome of rapid proliferation and differentiation of myeloid cells induced by these agents. doi: 10.1038/s41588-017-0001-z, 28. Science. Notably, no patients were required to permanently discontinue Ivosidenib as a result of these adverse events and there were no Ivosidenib-related fatalities, but two patients in the phase 1 Enasidenib trial died due to complications of IDH-DS (12, 13). Mutations in IDH3 isoforms, which form heterotetrameric complexes in mitochondria, are rarely seen in cancer, but there is some evidence that upregulation of wild-type IDH3 may contribute to various tumorigenic metabolic pathways (14, 15). Notably, early adverse event data from this study has halted clinical development of IDH305 because of dose-limiting toxicities such as hyperbilirubinemia and transaminitis (64). doi: 10.1158/2159-8290.CD-16-1034, 52. Wang JH, Chen WL, Li JM, Wu SF, Chen TL, Zhu YM, et al. The IDH2R140 mutation (in particular, the R140Q variant) is the most common, with the IDH1R132 and IDH2R172 mutations also appearing frequently in the literature (3, 12, 45, 46, 50–52).

Kernytsky A, Wang F, Hansen E, Schalm S, Straley K, Gliser C, et al. Type and frequency of IDH1 and IDH2 mutations are related to astrocytic and oligodendroglial differentiation and age: a study of 1,010 diffuse gliomas. Although IDH1/2 mutations are less common in pediatric AML (Table 1), studies on pediatric patients with cytogenetically normal AML have reported higher frequencies of IDH1/2 mutations (10.8%) than in cohorts with patients harboring various cytogenetics [32,33]. Cell Rep. (2017) 19:1858–73. Clinical trials have demonstrated the clinical benefit of venetoclax-based therapies in newly diagnosed AML, leading to the recent FDA approval of venetoclax in combination with hypomethylating agents or low-dose cytarabine for older adults with newly diagnosed AML. A handful of these are in use in clinical trials, but only two have been approved by the FDA; Enasidenib and Ivosidenib (10, 11). An initial screen of over 3 million compounds based on mutIDH enzymatic activity generated a small group of compounds—with IC50 ranging from 0.6 to 17.1 μM—for further evaluation. doi: 10.4329/wjr.v6.i8.583, 115. Although IDH inhibitors are being evaluated for clinical efficacy, an in-depth understanding of disease pathogenesis linked to IDH mutations is required to develop rational combination treatments and to be evaluated in the clinic. Ganguly BB, Kadam NN. doi: 10.1021/acschembio.6b00080, 27. Results presented at the 2018 ASCO Annual Meeting from data on 57 patients (31 treated with FT-2102, 27 treated with both FT-2102 and azacitidine) demonstrated a complete response rate of 38% with monotherapy and 27% with combination therapy (75). (2009) 361:1058–66. Ivosidenib was administered daily over 28-days cycles at doses ranging from 100 mg up to 1200 mg. Doses beyond 500 mg did not result in increased plasma 2HG reduction; therefore the 500 mg dose was selected for the dose-expansion arms, which included both enhancing and non-enhancing IDH-mutant gliomas (97). The most common adverse events (in ≥20% of the patients) were diarrhea, leukocytosis, febrile neutropenia, nausea, fatigue, dyspnea, prolongation of the QT interval, peripheral edema, anemia, pyrexia, and cough. Insulator dysfunction and oncogene activation in IDH mutant gliomas. IDH-DS has been reported as a severe adverse effect of interest in AML trials across nearly all of the mutIDH inhibitors, and warrants further discussion (12, 13, 64, 75). Dunn GP, Rinne ML, Wykosky J, Genovese G, Quayle SN, Dunn IF, et al. Oncol. The potential for isocitrate dehydrogenase mutations to produce 2-hydroxyglutarate depends on allele specificity and subcellular compartmentalization. There are also a handful of additional trials of Ivosidenib for hematological malignancies that are still in the planning stages (ClinicalTrials.gov NCT03564821, NCT03503409). Oncotarget. Mutational analysis reveals the origin and therapy-driven evolution of recurrent glioma. Watanabe T, Nobusawa S, Kleihues P, Ohgaki H. IDH1 mutations are early events in the development of astrocytomas and oligodendrogliomas. All of these compounds have shown limited toxicity thus far and are being pursued both as monotherapies and in combination with other leading chemotherapies.184,185. 6):vi18. Unlike in standard cytoreductive chemotherapy, treatment response occurred without a period of bone marrow hypoplasia, and bone marrow aspirates revealed that responders were characterized by robust myeloid differentiation and trilineage hematopoietic recovery. Permanent drug discontinuation was not required in any patients. Acta Neuropathol. Therapeutic targeting of histone modifications in adult and pediatric high-grade glioma. The allosteric IDH inhibitors, enasidenib and ivosidenib, effectively suppress production of 2-HG, releasing myeloid blasts from differentiation block.33–36. What are the roles of hypoxia-inducible factor (HIF) and its prolyl 4-hydroxylases in IDH-mutant tumors? Michael R. Grunwald, Mark J. Levis, in Seminars in Hematology, 2015, Many other targets and targeted therapies are being evaluated in AML. 119. One of the earliest, and most well-studied mutIDH1-specific inhibitors is AG-5198, a phenyl-glycine-based compound (Figure 2) (66).

Mutant IDH1 downregulates ATM and alters DNA repair and sensitivity to DNA damage independent of TET2. Enasidenib treatment also significantly prolonged survival in these models (51). Drugs. Shortly after the discovery of IDH1 mutations in AML, another landmark study reported the first case of IDH2-mutated AML, in which the R172 residue was mutated to lysine (18). 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.

J Biomol Screen. 2):PL04–05. For example, in addition to the development of IDH inhibitors, efforts are underway to broaden the array of treatments directed toward aberrant DNA methylation, which can be caused not only by mutations in IDH1 and IDH2 but also by mutations in other genes, including DNMT3A and TET2. (2016) 30:578–94. Tallman MS, Knight RD, Glasmacher AG, Dohner H. Phase III randomized, open-label study comparing the efficacy and safety of AG-221 vs conventional care regimens (CCR) in older patients with advanced acute myeloid leukemia (AML) with isocitrate dehydrogenase (IDH)-2 mutations in relapse or refractory to multiple prior treatments: the idhentify trial. Cho YS, Levell JR, Liu G, Caferro T, Sutton J, Shafer CM, et al. Two trials, a phase 1b/2 and a phase 2, are evaluating Enasidenib in combination with a DNA methyltransferase (DNMT) inhibitor, azacitidine, in newly-diagnosed and relapsed/refractory AML, respectively (ClinicalTrials.gov NCT02677922, NCT03683433). Other ongoing clinical trials of mutIDH inhibitor compounds in glioma (currently without early results) are also in phase 1 and are mostly in the early recruitment phase. J Clin Oncol. Leblebjian H, DeAngelo DJ, Skirvin JA, Stone RM, Wadleigh M, Werner L, et al. Oncotarget. While preliminary efficacy data has yet to be published, the most frequently observed adverse events included elevation of transaminases (ALT 44.2 and AST 38.5%) and headache (34.6%). In 2015, the first phase 1 data on the safety of Ivosidenib in patients with advanced glioma and other IDH-mutant solid tumors was presented at the annual EORTC-NCI-AAR Molecular Targets and Cancer Therapeutics Symposium and indicated that Ivosidenib treatment was well-tolerated with a positive pharmacokinetic profile (ClinicalTrials.gov NCT02073994) (95). EMBO Rep. (2011) 12:463–9. Another trial in the recruitment phase is examining simultaneous treatment with Ivosidenib and the chronic lymphocytic leukemia drug venetoclax in patients with relapsed or refractory AML (NCT03471260). Shortly after the 2017 phase 1 Enasidenib trial in AML, an independent differentiation syndrome review committee (DSRC) retrospectively analyzed possible cases of IDH-DS, identified distinguishing characteristics of patients who developed IDH-DS, such as fewer previous anticancer therapies and higher baseline peripheral blasts and lactate dehydrogenase levels, and outlined an easy-to-follow protocol for IDH-DS diagnosis and management (105). The 500 mg daily dose was chosen during the dose-escalation phase as it was noted that no additional inhibition of 2HG in plasma was observed at higher doses, and at this dose, a decrease in plasma 2HG to the level of healthy persons was achieved in most patients.
