CB-5339 is a second generation, potent and selective, orally bioavailable, ATP-competitive, small molecule inhibitor of valosin containing protein (VCP)/p97 [1,2]. CB-5339 is an ATP-competitive, small molecule inhibitor of p97 with IC50 of 53 nM [3].
CB-5339 effectively effect on a panel of 16 primary AML patient samples harboring diverse genetic backgrounds. The median IC50 value was 375 nM among these samples [1]. CB-5339 (200 to 1000 nM for 48 hours) induces in vitro loss of viability in AML cell lines (OCI-AML3, MOLM13, SET2 and HEL92.1.7 cells), as well as in fresh, patient-derived (PD) AML cells, including those with TP53 mutations and/or TP53 allelic loss, or with 3q26 (MECOM locus) lesions and EVI1 overexpression [2]. CB-5339 induced accumulation of polyubiquitylated proteins, retention of ERAD substrates, and lethal ER stress in cancer cells mediated by CHOP, DR5 and NOXA [2].
CB-5339 has higher bioavailability than CB-5083 [1]. Treatment with CB-5339 (90 mg/kg) reduced invasion of myeloid leukemia and prolonged survival in an MLL-AF9-driven PDX AML mouse model [1]. In a tail-vein infused, luciferase transduced, aggressive xenograft model of MOLM13 cells, after AML engraftment, co-treatment for 3 weeks with CB-5339 (50 mg/kg/day, PO) and either venetoclax (30 mg/kg/day, PO) or OTX015 (30 mg/kg/day, PO), as compared to treatment with vehicle or each drug alone, significantly reduced the AML burden and improved median and overall survival of the NSG mice, without inducing significant toxicity [2].

Targeting acute myeloid leukemia dependency on VCP-mediated DNA repair through a selective second-generation small-molecule inhibitor
Sci Transl Med 2021 Mar 31;13(587):eabg1168.PMID:33790022DOI:10.1126/scitranslmed.abg1168.
The development and survival of cancer cells require adaptive mechanisms to stress. Such adaptations can confer intrinsic vulnerabilities, enabling the selective targeting of cancer cells. Through a pooled in vivo short hairpin RNA (shRNA) screen, we identified the adenosine triphosphatase associated with diverse cellular activities (AAA-ATPase) valosin-containing protein (VCP) as a top stress-related vulnerability in acute myeloid leukemia (AML). We established that AML was the most responsive disease to chemical inhibition of VCP across a panel of 16 cancer types. The sensitivity to VCP inhibition of human AML cell lines, primary patient samples, and syngeneic and xenograft mouse models of AML was validated using VCP-directed shRNAs, overexpression of a dominant-negative VCP mutant, and chemical inhibition. By combining mass spectrometry-based analysis of the VCP interactome and phospho-signaling studies, we determined that VCP is important for ataxia telangiectasia mutated (ATM) kinase activation and subsequent DNA repair through homologous recombination in AML. A second-generation VCP inhibitor, CB-5339, was then developed and characterized. Efficacy and safety of CB-5339 were validated in multiple AML models, including syngeneic and patient-derived xenograft murine models. We further demonstrated that combining DNA-damaging agents, such as anthracyclines, with CB-5339 treatment synergizes to impair leukemic growth in an MLL-AF9-driven AML murine model. These studies support the clinical testing of CB-5339 as a single agent or in combination with standard-of-care DNA-damaging chemotherapy for the treatment of AML.
Inhibitors of the ATPase p97/VCP: From basic research to clinical applications
Cell Chem Biol 2023 Jan 19;30(1):3-21.PMID:36640759DOI:10.1016/j.chembiol.2022.12.007.
Protein homeostasis deficiencies underlie various cancers and neurodegenerative diseases. The ubiquitin-proteasome system (UPS) and autophagy are responsible for most of the protein degradation in mammalian cells and, therefore, represent attractive targets for cancer therapy and that of neurodegenerative diseases. The ATPase p97, also known as VCP, is a central component of the UPS that extracts and disassembles its substrates from various cellular locations and also regulates different steps in autophagy. Several UPS- and autophagy-targeting drugs are in clinical trials. In this review, we focus on the development of various p97 inhibitors, including the ATPase inhibitors CB-5083 and CB-5339, which reached clinical trials by demonstrating effective anti-tumor activity across various tumor models, providing an effective alternative to targeting protein degradation for cancer therapy. Here, we provide an overview of how different p97 inhibitors have evolved over time both as basic research tools and effective UPS-targeting cancer therapies in the clinic.
NMS-873 Leads to Dysfunctional Glycometabolism in A p97-Independent Manner in HCT116 Colon Cancer Cells
Pharmaceutics 2022 Mar 31;14(4):764.PMID:35456598DOI:10.3390/pharmaceutics14040764.
Adenosine triphosphate (ATP)-competitive p97 inhibitor CB-5339, the successor of CB-5083, is being evaluated in Phase 1 clinical trials for anti-cancer therapy. Different modes-of-action p97 inhibitors such as allosteric inhibitors are useful to overcome drug-induced resistance, one of the major problems of targeted therapy. We previously demonstrated that allosteric p97 inhibitor NMS-873 can overcome CB-5083-induced resistance in HCT116. Here we employed chemical proteomics and drug-induced thermal proteome changes to identify drug targets, in combination with drug-resistant cell lines to dissect on- and off-target effects. We found that NMS-873 but not CB-5083 affected glycometabolism. By establishing NMS-873-resistant HCT116 cell lines and performing both cell-based and proteomic analysis, we confirmed that NMS-873 dysregulates glycometabolism in a p97-independent manner. We then used proteome integral solubility alteration with a temperature-based method (PISA T) to identify NDUFAF5 as one of the potential targets of NMS-873 in the mitochondrial complex I. We also demonstrated that glycolysis inhibitor 2-DG enhanced the anti-proliferative effect of NMS-873. The polypharmacology of NMS-873 can be advantageous for anti-cancer therapy for colon cancer.
Comparative Oncology Assessment of a Novel Inhibitor of Valosin-Containing Protein in Tumor-Bearing Dogs
Mol Cancer Ther 2022 Oct 7;21(10):1510-1523.PMID:35876604DOI:10.1158/1535-7163.MCT-22-0167.
Pet dogs with naturally occurring cancers play an important role in studies of cancer biology and drug development. We assessed tolerability, efficacy, and pharmacokinetic/pharmacodynamic relationships with a first-in-class small molecule inhibitor of valosin-containing protein (VCP/p97), CB-5339, administered to 24 tumor-bearing pet dogs. Tumor types assessed included solid malignancies, lymphomas, and multiple myeloma. Through a stepwise dose and schedule escalation schema, we determined the maximum tolerated dose to be 7.5 mg/kg when administered orally on a 4 days on, 3 days off schedule per week for 3 consecutive weeks. Adverse events were minimal and mainly related to the gastrointestinal system. Pharmacokinetic/pharmacodynamic data suggest a relationship between exposure and modulation of targets related to induction of the unfolded protein response, but not to tolerability of the agent. An efficacy signal was detected in 33% (2/6) of dogs with multiple myeloma, consistent with a mechanism of action relating to induction of proteotoxic stress in a tumor type with abundant protein production. Clinical trials of CB-5339 in humans with acute myelogenous leukemia and multiple myeloma are ongoing.
