[VIRTUAL] The Combined Treatment with the FLT3-Inhibitor AC220 and the Complex I Inhibitor Iacs-010759 Synergistically Depletes Wt- and FLT3-Mutated Acute Myeloid Leukemia Cells (Poster Hall (Virtual Meeting)) - Nov 5, 2020 - Abstract #ASH2020ASH_2919; Thus, we investigated more in-depth the synergism between IACS-010759 (10nM) and 13 FLT3 inhibitors, all currently in clinical trials (AC220, sorafenib, gilteritinib, sunitinib, ponatinib, midostaurin, ibrutinib, TP-0903, crenolanib, tandutinib, FF-10101, lestaurtinib, and KW-2449; 0.0128:5x:5000nM), in AML cell lines (FLT3-wt KG-1, U937, OCI-AML2, OCI-AML3; and FLT3-mutant MOLM-13 and MOLM-14)...Influx inhibition of both the two main carbon sources, glucose and glutamine, was observed leading to impairment of the TCA cycle and glycolysis for energy production, as well as pentose phosphate pathway and de novo nucleotide biosynthesis. In conclusion, we identified a novel drug combination AC220 and IACS-010759 which synergistically inhibits AML cell growth regardless of FLT3 mutation at least by metabolism disruption.

[VIRTUAL] The Direct Interactions with Bone Marrow Microenvironment Confer Resistance to the Inhibition of Oxidative Phosphorylation in AML (Poster Hall (Virtual Meeting)) - Nov 5, 2020 - Abstract #ASH2020ASH_1938; We investigated how the BM microenvironment impacts the response to energy-depriving OxPhos inhibition in AML using a novel complex I OxPhos inhibitor (OxPhosi), IACS-010759...Taken together, our data highlight the importance of direct interaction with BM stromal cells as well as complementally modification of amino acid- and lipid metabolism for the resistance of AML cells to OxPhos inhibition. While the mechanisms of stroma-leukemia interactions are likely complex, reducing the adhesion of AML cells to nurturing stromal cells ameliorates the resistance to the metabolic and energetic consequences of OxPhos inhibition.

[VIRTUAL] Angiogenesis inhibitors strongly synergize with therapeutics targeting tumor metabolism () - Oct 24, 2020 - Abstract #SNO2020SNO_439; The same results were recapitulated with the anti-VEGFA antibody, Avastin, and the OxPhos inhibitor could be substituted with the Enolase inhibitor HEX, with similar effects...Together, these results suggest that Angiogenesis inhibitors synergize broadly with cancer therapies targeting metabolism, allowing the realization of the full potential of these previously disappointing drugs. Our results warrant systematic combination clinical trials between angiogenesis inhibitors and established, as well as emerging anti-metabolic cancer therapies.

Journal: A novel mitochondrial inhibitor blocks MAPK pathway and overcomes MAPK inhibitor-resistance in melanoma. (Pubmed Central) - Sep 9, 2020 OXPHOS inhibition as part of a combinatorial regimen with XRT is a promising strategy to address PD-1–resistant NSCLC, and this combination is being tested clinically. Targeting OxPhos with OPi has significant anti-tumor activity in MAPKi-resistant, BRAF-mutant melanomas, and merits further clinical investigation as a potential new strategy to overcome intrinsic and acquired resistance to MAPKi in patients.

(Pubmed Central) - Aug 18, 2020 In this regard, IACS-010759 is a novel high affinity inhibitor of OxPhos targeting mitochondrial complex-I that has recently completed a Phase-I clinical trial in leukemia...Pilot [F]FAZA PET scans of a patient with grade IV glioblastoma yielded highly reproducible, high-contrast images of hypoxia in vivo as validated by CA-IX and GLUT-1 IHC ex vivo. Thus, [F]FAZA PET imaging provided direct evidence for the presence of consumptive hypoxia in vivo, the capacity for targeted reversal of consumptive hypoxia through the inhibition of OxPhos, and a highly-coupled mechanism-specific PD biomarker ready for translation.

Preclinical, Journal: Inhibition of Oxidative Phosphorylation Reverses Bone Marrow Hypoxia Visualized in Imageable Syngeneic B-ALL Mouse Model. (Pubmed Central) - Jul 24, 2020 Remarkably, treatment of leukemic mice with IACS-010759, a pharmacological inhibitor of mitochondrial Complex I, substantially increased pO in the BM with advanced B-ALL, and it alleviated intracellular hypoxia reported by pimonidazole staining...Our results suggest that B-ALL expansion in BM is associated with intense oxidative phosphorylation (OxPhos) leading to the onset of metabolic BM hypoxia despite increased BM vascularization. Targeting mitochondrial respiration may be a novel approach to counteract BM hypoxia in B-ALL and, possibly, tumor hypoxia in other OxPhos-reliant malignancies.

Journal: Metabolic reprogramming toward oxidative phosphorylation identifies a therapeutic target for mantle cell lymphoma. (Pubmed Central) - Jul 16, 2020 Inhibition of OXPHOS with a clinically applicable small molecule, IACS-010759, which targets complex I of the mitochondrial electron transport chain, results in marked growth inhibition in vitro and in vivo in ibrutinib-resistant patient-derived cancer models. This work suggests that targeting metabolic pathways to subvert therapeutic resistance is a clinically viable approach to treat highly refractory malignancies.
