Pim Kinase Inhibitors Increase Gilteritinib Cytotoxicity in FLT3-ITD Acute Myeloid Leukemia Through GSK-3β Activation and c-Myc and Mcl-1 Proteasomal Degradation

Article

Abstract:

Acute myeloid leukemia (AML) with fms-like tyrosine kinase 3 internal tandem duplication (FLT3-ITD) has poor outcomes. FLT3-ITD drives constitutive and aberrant FLT3 signaling, activating STAT5 and upregulating the downstream oncogenic serine/threonine kinase Pim-1. FLT3 inhibitors are in clinical use, but with limited and transient efficacy. We previously showed that concurrent treatment with Pim and FLT3 inhibitors increases apoptosis induction in FLT3-ITD–expressing cells through posttranslational downregulation of Mcl-1. Here we further elucidate the mechanism of action of this dual targeting strategy. Cytotoxicity, apoptosis and protein expression and turnover were measured in FLT3-ITD–expressing cell lines and AML patient blasts treated with the FLT3 inhibitor gilteritinib and/or the Pim inhibitors AZD1208 or TP-3654. Pim inhibitor and gilteritinib cotreatment increased apoptosis induction, produced synergistic cytotoxicity, downregulated c-Myc protein expression, earlier than Mcl-1, increased turnover of both proteins, which was rescued by proteasome inhibition, and increased efficacy and prolonged survival in an in vivo model. Gilteritinib and Pim inhibitor cotreatment of Ba/F3-ITD cells infected with T58A c-Myc or S159A Mcl-1 plasmids, preventing phosphorylation at these sites, did not downregulate these proteins, increase their turnover or increase apoptosis induction. Moreover, concurrent treatment with gilteritinib and Pim inhibitors dephosphorylated (activated) the serine/threonine kinase glycogen synthase kinase-3β (GSK-3β), and GSK-3β inhibition prevented c-Myc and Mcl-1 downregulation and decreased apoptosis induction. The data are consistent with c-Myc T58 and Mcl-1 S159 phosphorylation by activated GSK-3β as the mechanism of action of gilteritinib and Pim inhibitor combination treatment, further supporting GSK-3β activation as a therapeutic strategy in FLT3-ITD AML.

Significance::

FLT3-ITD is present in 25% of in AML, with continued poor outcomes. Combining Pim kinase inhibitors with the FDA-approved FLT3 inhibitor gilteritinib increases cytotoxicity in vitro and in vivo through activation of GSK-3β, which phosphorylates and posttranslationally downregulates c-Myc and Mcl-1. The data support efficacy of GSK-3β activation in FLT3-ITD AML, and also support development of a clinical trial combining the Pim inhibitor TP-3654 with gilteritinib.

Myelofibrosis (MF) is the deadliest form of myeloproliferative neoplasm (MPN). The JAK inhibitor Ruxolitinib can reduce constitutional symptoms but it does not substantially improve bone marrow fibrosis. Pim1 expression is significantly elevated in MPN/MF hematopoietic progenitors. Here, we show that genetic ablation of Pim1 blocked the development of myelofibrosis induced by Jak2V617F and MPLW515L. Pharmacologic inhibition of Pim1 with a second-generation Pim kinase inhibitor TP-3654 significantly reduced leukocytosis and splenomegaly, and attenuated bone marrow fibrosis in Jak2V617F and MPLW515L mouse models of MF. Combined treatment of TP-3654 and Ruxolitinib resulted in greater reduction of spleen size, normalization of blood leukocyte counts and abrogation of bone marrow fibrosis in murine models of MF. TP-3654 treatment also preferentially inhibited Jak2V617F mutant hematopoietic progenitors in mice. Mechanistically, we show that TP-3654 treatment significantly inhibits mTORC1, MYC and TGF-β signaling in Jak2V617F mutant hematopoietic cells and diminishes the expression of fibrotic markers in the bone marrow. Collectively, our results suggest that Pim1 plays an important role in the pathogenesis of MF, and inhibition of Pim1 with TP-3654 might be useful for treatment of MF.

PIM1 (Moloney Murine Leukemia Provirus Integration Site) Inhibition Decreases the Nonhomologous End-Joining DNA Damage Repair Signaling Pathway in Pulmonary Hypertension

Q1 · MEDICINE

Article

Author: Boucherat, Olivier ; Paradis, Renée ; Lampron, Marie-Claude ; Meloche, Jolyane ; Nadeau, Valérie ; Provencher, Steeve ; Grobs, Yann ; Samson, Nolwenn ; Paulin, Roxane ; Bonnet, Sébastien ; Potus, François ; Tremblay, Ève ; Vitry, Géraldine

Objective::

Pulmonary arterial hypertension (PAH) is a fatal disease characterized by the narrowing of pulmonary arteries (PAs). It is now established that this phenotype is associated with enhanced PA smooth muscle cells (PASMCs) proliferation and suppressed apoptosis. This phenotype is sustained in part by the activation of several DNA repair pathways allowing PASMCs to survive despite the unfavorable environmental conditions. PIM1 (Moloney murine leukemia provirus integration site) is an oncoprotein upregulated in PAH and involved in many prosurvival pathways, including DNA repair. The objective of this study was to demonstrate the implication of PIM1 in the DNA damage response and the beneficial effect of its inhibition by pharmacological inhibitors in human PAH-PASMCs and in rat PAH models.

Approach and Results::

We found in vitro that PIM1 inhibition by either SGI-1776, TP-3654, siRNA (silencer RNA) decreased the phosphorylation of its newly identified direct target KU70 (lupus Ku autoantigen protein p70) resulting in the inhibition of double-strand break repair (Comet Assay) by the nonhomologous end-joining as well as reduction of PAH-PASMCs proliferation (Ki67-positive cells) and resistance to apoptosis (Annexin V positive cells) of PAH-PASMCs. In vivo, SGI-1776 and TP-3654 given 3× a week, improved significantly pulmonary hemodynamics (right heart catheterization) and vascular remodeling (Elastica van Gieson) in monocrotaline and Fawn-Hooded rat models of PAH.

Conclusions::

We demonstrated that PIM1 phosphorylates KU70 and initiates DNA repair signaling in PAH-PASMCs and that PIM1 inhibitors represent a therapeutic option for patients with PAH.

Sumitomo Pharma America Presents New Data on Nuvisertib and Enzomenib at the 2024 American Society of Hematology Annual Meeting

Latest results in Phase 1/2 studies show promise for two investigational treatments for patients with relapsed/refractory blood and bone marrow cancers Nuvisertib (TP-3654), an investigational oral small molecule highly selective PIM1 kinase inhibitor, is being evaluated in a Phase 1/2 study in patients with relapsed/refractory myelofibrosis Enzomenib (DSP-5336), an investigational, oral small molecule designed to inhibit the menin and KMT2A protein interaction, is being evaluated in a Phase 1/2 study in patients with relapsed/refractory acute leukemia MARLBOROUGH, Mass., Dec. 9, 2024 /PRNewswire/ -- Sumitomo Pharma America, Inc. (SMPA) today presented new clinical data supporting further development of nuvisertib, an investigational small molecule being researched for the treatment of relapsed/refractory myelofibrosis (MF), and enzomenib, an investigational oral small molecule being researched for relapsed/refractory acute leukemia, at the 66th American Society of Hematology (ASH) Annual Meeting & Exposition. Preliminary data presented from the ongoing Phase 1/2 study of nuvisertib monotherapy (N=74) in patients with relapsed/refractory MF show nuvisertib was well tolerated with no dose-limiting toxicities (DLTs). Preliminary data in evaluable patients showed clinical activity including spleen volume reduction (SVR25 of 22.2%), symptom reduction (TSS50 of 44.4%), and bone marrow fibrosis (47.8% patients) and hemoglobin (25% patients) and platelet count (27.6% patients) improvement. Additional data presented show nuvisertib treatment led to significant cytokine modulation (e.g. EN-RAGE, IL-18, MIP-1β, and adiponectin) over time correlating with spleen and symptom responses. The global study has been expanded to evaluate nuvisertib add-on to ruxolitinib, the first approved Janus-associated kinase (JAK) inhibitor, and in combination with momelotinib, a recently approved JAK inhibitor for MF patients with anemia, to assess safety and potential clinical activity. New preliminary clinical and translational data from the enzomenib Phase 1/2 study were also presented at the conference by Dr. Joshua Zeidner from the University of North Carolina. The safety population included 84 total patients with acute leukemia, most of whom (94%, 79/84) had acute myeloid leukemia (AML). The study population was diverse, with 47.6% non-white (40/84), and also heavily pre-treated, with a median of 3 prior regimens. In these patients, enzomenib was administered twice daily in continuous 28-day study cycles at dose levels from 40 mg BID up to 300 mg BID. Enzomenib was well tolerated with low overall rates of drug-related adverse events and no dose limiting toxicity (DLT) reported. Differentiation syndrome was reported in 10.7% of patients but did not result in patient deaths nor did it require permanent discontinuations of enzomenib. Also presented were clinical activity results from the dose optimization cohorts at the dose levels of 200 mg BID and 300 mg BID. The data included results from all patients with KMT2A rearrangement (KMT2Ar) or NPM1 mutation (NPM1m) who had received at least one dose of enzomenib and who had not received a menin inhibitor previously. In 23 patients with KMT2Ar, the Objective Response Rate (ORR) using ELN 2017 criteria was 65.2% (15/23) and the proportion to achieve CR+CRh was 30.4% (7/23). In the subset of patients with KMT2Ar to receive 300 mg BID (n = 15), the ORR was 73.3% (11/15) and CR+CR was 40% (6/15). In the 17 total patients with NPM1 mutation (NPM1m) who received 200 mg BID or 300 mg BID, the ORR was 58.8% (10/17) and the proportion to achieve CR+CRh was 47.1% (8/17). The 400 mg BID dose optimization cohort is ongoing, with 21 patients enrolled as of the clinical cut-off and data planned for presentation at a future conference. These encouraging clinical activity results combined with an excellent safety profile suggest that enzomenib may play an important role in the treatment of patients with relapsed/refractory acute leukemia with KMT2A rearrangement or NPM1 mutation. "These data signal growing momentum in our oncological pipeline and an important milestone in our development of new treatments for relapsed/refractory MF and acute leukemia," said Tsutomu Nakagawa, Ph.D., President and Chief Executive Officer of SMPA. "With these promising results in hand, we remain committed to advancing nuvisertib and enzomenib as we believe our investigational therapies may have the potential to improve the lives of patients living with these critical cancers who do not respond to currently available therapeutics." MF is a rare type of blood cancer that is characterized by the buildup of fibrous tissue in the bone marrow, which can affect the production of blood cells. This buildup is caused by a dysregulation in the JAK signaling pathway. MF is a serious and rare disease with 0.7 new cases per 100,000 people worldwide each year.4 Leukemia is a type of cancer that forms in blood-forming tissue, characterized by the uncontrolled growth of blood cells, usually white blood cells, in the bone marrow. Acute leukemia, a form of leukemia, requires immediate treatment as blood cells multiply rapidly leading to a sudden onset of symptoms.1 Approximately 30% of AML patients have NPM1 mutations2 and 5-10% of AML patients have KMT2A (MLL) rearrangements.3 "Patients and families living with incurable cancers of MF and AML are in need of new treatment options – and we are encouraged by the promising clinical activity for both nuvisertib and enzomenib," said Jatin Shah, M.D., Chief Medical Officer, Oncology, SMPA. "This additional preliminary data reinforces the strong potential for PIM1 inhibition in myelofibrosis, and for menin inhibitors in acute leukemia." About enzomenib (DSP-5336) Enzomenib (DSP-5336) is an investigational small molecule inhibitor of the menin and mixed-lineage leukemia (MLL) protein interaction. Menin is a scaffold nuclear protein which plays key roles in gene expression and protein interactions involved in many biological pathways, including cell growth, cell cycle, genomic stability, and hematopoiesis.5,6 In preclinical studies, enzomenib has shown selective growth inhibition in human acute leukemia cell lines with KMT2A (MLL) rearrangements or NPM1 mutations.5,7 Enzomenib reduced the expression of the leukemia-associated genes HOXA9 and MEIS1, and increased the expression of the differentiation gene CD11b in human acute leukemia cell lines with MLL rearrangements and NPM1 mutation.8,9 The safety and efficacy of enzomenib is currently being clinically evaluated in a Phase 1/2 dose escalation/dose expansion study in patients with relapsed or refractory acute leukemia (NCT04988555). The FDA granted Orphan Drug Designation for enzomenib for the indication of acute myeloid leukemia in June 2022. The FDA granted Fast Track Designation for enzomenib for the indication of relapsed or refractory acute myeloid leukemia with MLLr or NPM1m in June 2024. The PMDA granted Orphan Drug Designation for enzomenib for the indication of relapsed or refractory acute myeloid leukemia with MLLr or NPM1m in September 2024. About nuvisertib (TP-3654) Nuvisertib (TP-3654) is an oral investigational selective inhibitor of PIM1 kinase, which has shown potential antitumor and antifibrotic activity through multiple pathways, including induction of apoptosis in preclinical models.10,11 Nuvisertib was observed to inhibit proliferation and induce apoptosis in murine and human hematopoietic cells expressing the clinically relevant JAK2V617F mutation.10 Nuvisertib alone and in combination with ruxolitinib showed white blood cell and neutrophil count normalization, and also reduced spleen size and bone marrow fibrosis in JAK2V617F and MPLW515L murine models of myelofibrosis.11 The safety and efficacy of nuvisertib is currently being clinically evaluated in a Phase 1/2 study in patients with intermediate and high-risk myelofibrosis (NCT04176198). The U.S. Food and Drug Administration (FDA) granted Orphan Drug Designation for nuvisertib for the indication of myelofibrosis in May 2022. The PMDA granted Orphan Drug Designation for nuvisertib for the indication of myelofibrosis in November 2024.

Sumitomo Pharma Presents Encouraging New Data on DSP-5336 Clinical Activity at the American Society of Hematology Annual Meeting

– DSP-5336, an Investigational Menin and Mixed-lineage Leukemia Inhibitor, is Being Evaluated in Patients with Relapsed or Refractory Acute Leukemia, with Positive Preliminary Data Presented at ASH – CAMBRIDGE, Mass., Dec. 11, 2023 /PRNewswire/ -- Sumitomo Pharma America, Inc. (SMPA) today announced new data from the ongoing Phase 1/2 first-in-human study of DSP-5336, in patients with relapsed or refractory acute leukemia, presented at the 65th American Society of Hematology (ASH) Annual Meeting & Exposition. DSP-5336 is an investigational small molecule inhibitor of the menin and mixed-lineage leukemia (MLL) protein interaction, which plays key roles in biological pathways, including cell growth regulation, cell cycle control, genomic stability, bone development, and hematopoiesis.1,2,3 Data from the open-label, ongoing dose determination portion of the Phase 1/2 study enrolling patients with relapsed or refractory acute leukemia with relevant genomic alterations receiving oral DSP-5336 up to 200 mg twice-daily were presented at the meeting. In the ongoing study, patients are continuing to dose escalate and are now at therapeutic levels. Preliminary results presented at ASH 2023 included four evaluable patients treated with DSP-5336 200 mg twice-daily, three of whom showed objective responses. Clinical remission with partial hematologic recovery and clinical remission with incomplete count recovery (CRh/CRi) was achieved by one patient, CRi was achieved by one patient, and morphologic leukemia-free state (MLFS) was achieved by one patient. All patients cleared peripheral blasts. To date, DSP-5336 has been well-tolerated, notably, with no treatment-related cardiac effects, including QT prolongation. Additionally, differentiation syndrome has not been observed at the 200 mg twice-daily dose. "While these data are early-stage, it is encouraging to see promising clinical activity from DSP-5336, particularly with limited safety signals and a clean tolerability pro date," said Navel Daver, M.D., Director, Department of Leukemia, Division of Leukemia Research Alliance Program, The University of Texas MD Anderson Cancer Center and lead author on the DSP-5336 poster at ASH. "DSP-5336 is an investigational targeted therapy that inhibits menin-MLL protein interaction. Inhibition of the menin-MLL protein interaction may be able to reverse the leukemogenic activity of MLL fusion proteins and may be a future therapeutic option for acute leukemia." Leukemia is a type of cancer that forms in blood-forming tissue, characterized by the uncontrolled growth of blood cells, usually white blood cells in the bone marrow.4 Acute leukemia, a form of leukemia, requires immediate treatment as blood cells multiply rapidly leading to a sudden onset of symptoms.4 "There is a high unmet need for new and innovative approaches in the treatment of relapsed or refractory acute leukemia, as many patients have limited options to treat the disease or do not respond to currently available cancer therapies," said Jatin Shah, M.D., Chief Oncology Development Officer, SMPA. "We believe we are close to determining the appropriate therapeutic dose of DSP-5336 in our ongoing study and were encouraged by our discussions on these results with the leading hematological oncology community at ASH. We look forward to continuing the study of DSP-5336 as a monotherapy and to exploring additional combination studies." Additional SMPA data presented at ASH included an oral presentation of encouraging preliminary results from the ongoing Phase 1/2 study of TP-3654 monotherapy in patients with relapsed or refractory myelofibrosis who were previously treated with or ineligible for a JAK inhibitor. About DSP-5336 DSP-5336 is an investigational small molecule inhibitor of the menin and mixed-lineage leukemia (MLL) protein interaction. Menin is a scaffold nuclear protein that plays various key roles in biological pathways, including cell growth regulation, cell cycle control, genomic stability, bone development, and hematopoiesis.1,2 In preclinical studies, DSP-5336 has shown selective growth inhibition in human acute leukemia cell lines with KMT2A (MLL) rearrangements or NPM1 mutations.1,3 DSP-5336 showed induced reduction of gene expression of HOXA9 and MEIS1, which are highly expressing leukemia associate genes, and increased expression of differentiation marker gene CD11b in the human acute leukemia cell lines with MLL rearrangements.5,6 DSP-5336 also showed growth inhibition and changes of gene expression levels of HOXA9, MEIS1 and CD11b on human acute leukemia patient samples with MLL rearrangements or NPM1 mutations.5,6 The safety and efficacy of DSP-5336 is currently being clinically evaluated in a Phase 1/2 dose escalation/dose expansion study in patients with relapsed or refractory acute leukemia (NCT04988555). The FDA granted Orphan Drug Designation for DSP-5336 for the indication of acute myeloid leukemia in June 2022. About TP-3654 TP-3654 is an oral investigational inhibitor of PIM1 kinase, which has shown potential antitumor and antifibrotic activity through multiple pathways, including induction of apoptosis in preclinical models.7,8 TP-3654 was observed to inhibit proliferation and induce apoptosis in murine and human hematopoietic cells expressing the clinically relevant JAK2V617F mutation.7 TP-3654 alone and in combination with ruxolitinib showed white blood cell and neutrophil count normalization, and also reduced spleen size and bone marrow fibrosis in JAK2V617F and MPLW515L murine models of myelofibrosis.8 The safety and efficacy of TP-3654 is currently being clinically evaluated in a Phase 1/2 study in patients with intermediate and high-risk myelofibrosis (NCT04176198).

Sumitomo Pharma America to Present Preliminary Clinical Data Evaluating Investigational Oncology Agents TP-3654 and DSP-5336 at the American Society of Hematology Annual Meeting

– ASH Preliminary Data Includes New Clinical Results in Relapsed or Refractory Myelofibrosis (TP-3654) and Relapsed or Refractory Acute Leukemia (DSP-5336) – CAMBRIDGE, Mass., Nov. 3, 2023 /PRNewswire/ -- Sumitomo Pharma America, Inc. (SMPA) today announced preliminary clinical data for investigational agents TP-3654, a selective oral PIM1 kinase inhibitor, and DSP-5336, an inhibitor of the menin and mixed-lineage leukemia (MLL) protein interaction. These data will be presented at the 65th American Society of Hematology (ASH) Annual Meeting & Exposition, held December 9-12 in San Diego, Calif. Preliminary results from the ongoing Phase 1/2 study of TP-3654 monotherapy in patients with relapsed or refractory myelofibrosis who were previously treated with or ineligible for a JAK inhibitor will be presented in an oral presentation at ASH. In this study, oral TP-3654 was well-tolerated with limited myelosuppressive adverse events. TP-3654 exhibited early signs of clinical activity including spleen volume reduction, total symptom score improvement, and correlating cytokine reductions. SMPA will also present a poster on preliminary clinical data from the ongoing Phase 1/2 first-in-human study of oral DSP-5336, in patients with relapsed or refractory acute leukemia. Preliminary data showed that DSP-5336 was well-tolerated with no dose limiting toxicities, including no observed cardiac signals. Target pharmacodynamic changes were observed with treatment, including rapid decreases in genes commonly expressed in leukemia (HOXA9, MEIS1, and PBX3). These changes were seen particularly in patients with acute myeloid leukemia characterized by a KMT2A (MLL) gene rearrangement or a mutation in the NPM1 gene. "We are encouraged by the early signs of clinical activity shown in the preliminary results from the TP-3654 and DSP-5336 Phase 1/2 trials. We look forward to sharing the data and having important scientific engagement involving both agents at the annual ASH meeting in December," said Jatin Shah, M.D., Chief Oncology Development Officer, SMPA. "Improving patient outcomes and developing new oncological treatments is a primary focus for SMPA and we remain committed to exploring the potential of our diverse research pipeline." About TP-3654 TP-3654 is an oral investigational inhibitor of PIM1 kinase, which has shown potential antitumor and antifibrotic activity through multiple pathways, including induction of apoptosis in preclinical models.1,2 TP-3654 was observed to inhibit proliferation and increase apoptosis in murine and human hematopoietic cells expressing the clinically relevant JAK2V617F mutation.2 TP-3654 alone and in combination with ruxolitinib showed white blood cell and neutrophil count normalization, and also reduced spleen size and bone marrow fibrosis in JAK2V617F and MPLW515L murine models of myelofibrosis.2 The safety and efficacy of TP-3654 is currently being clinically evaluated in a Phase 1/2 study in patients with intermediate and high-risk myelofibrosis (NCT04176198). The U.S. Food and Drug Administration (FDA) granted Orphan Drug Designation for TP-3654 for the indication of myelofibrosis in May 2022. About DSP-5336 DSP-5336 is an investigational small molecule inhibitor of the menin and mixed-lineage leukemia (MLL) protein interaction. Menin is a scaffold nuclear protein that plays various key roles in biological pathways, including cell growth regulation, cell cycle control, genomic stability, bone development, and hematopoiesis.3,4 In preclinical studies, DSP-5336 has shown selective growth inhibition in human acute leukemia cell lines with KMT2A (MLL) rearrangements or NPM1 mutations.3,5 The safety and efficacy of DSP-5336 is currently being clinically evaluated in a Phase 1/2 dose escalation/dose expansion study in patients with relapsed or refractory acute leukemia (NCT04988555). The FDA granted Orphan Drug Designation for DSP-5336 for the indication of acute myeloid leukemia in June 2022.
