INCB053914 is a novel, potent, selective, and ATP-competitive small molecule pan-inhibitor of PIM (Proviral Integration site of Moloney murine leukemia virus) kinases with IC50 values of 0.24 nM, 30 nM and 0.12 nM for PIM1, PIM2 and PIM3 respectively in biochemical assays. In cell proliferation assays, INCB053914 is active as a single agent in the majority of cell lines derived from different hematological malignancies, including MM, AML, DLBCL, MCL and T-ALL, with IC50values ranging from 3 - 300 nM. INCB053914 synergizes with a variety of cytotoxic and targeted agents, reducing the viability of a panel of hematological tumor cell lines. In pharmacodynamic assays, INCB053914 inhibits phosphorylation of S6RP, P70S6K, 4E-BP-1 and BAD, known PIM kinase targets. INCB053914 may have therapeutic utility in hematologic malignancies when combined with other inhibitors of oncogenic kinases or standard chemotherapeutics.

Biological Activity
| ln Vitro | All multiple myeloma (MM) cell lines examined are inhibited in their ability to proliferate by usansertib; typical GI50 values for AML, MM, DLBCL, MCL, and T-ALL cell lines range from 13.2 nM to 230.0 nM [1]. In MOLM-16 (AML) phosphorylated), Pfeiffer (DLBCL), and KMS-12-PE/BM (MM) cell lines, umansertib (0.1, 0.3, 1, 3, 10, 30, 100, 300, and 1000 nM) inhibits downstream PIM kinase substrates (p70S6K/S6 and 4E-BP1) in a dose-dependent manner [1]. In MOLM-16 and KMS-12-BM cells, PIM kinase-mediated BAD phosphorylation is especially susceptible to Uzansertib inhibition (average IC50 of 4 nM and 27 nM, respectively) [1]. |
| ln Vivo | Uzansertib (25–100 mg/kg; oral; twice daily; for 15 days) dose-dependently suppresses tumor growth in mice expressing KMS-12-BM (MM) or MOLM-16 (AML)[1]. Four hours after injection, uzansertib showed dose-dependent reduction of BAD phosphorylation in comparison to vehicle (IC50=70 nM for MOLM-16 tumors and IC50=145 nM for KMS-12-BM tumors) [1]. |
| Animal Protocol |
Animal/Disease Models: Female immunocompromised (severe combined immunodeficiency [SCID]) mice (5-9 weeks old) [1] carrying MOLM-16 (AML) or KMS-12-BM (MM) Doses: 25, 50 , 75, 100 mg/kg. Doses: Oral; twice a day; for 15 days. Experimental Results: Inhibited tumor growth in mice in a dose-dependent manner. |

| Additional Infomation |
Uzansertib is under investigation in clinical trial NCT02587598 (Study of INCB053914 in Subjects With Advanced Malignancies). Uzansertib is an orally available, small molecule and selective ATP-competitive pan-inhibitor of proviral integration sites for Moloney murine leukemia virus (PIM) kinases, with potential antineoplastic activity. Upon oral administration, uzansertib binds to and inhibits the activities of the three PIM isoforms, PIM1, PIM2 and PIM3. This prevents phosphorylation of their downstream targets and inhibits proliferation in cells that overexpress PIMs. PIMs, constitutively active proto-oncogenic serine/threonine kinases upregulated in various types of cancers, play key roles in tumor cell proliferation and survival. |
