Biological Activity of CH5183284 (Debio-1347)

DescriptionCH5183284 is an orally available and selective FGFR inhibitor with IC50s of 9.3, 7.6, and 22 nM for FGFR1, FGFR2, FGFR3, and FGFR4, respectively.In Vitro:CH5183284 is well balanced in cellular antiproliferative activity against SNU-16 and stability in human liver microsome. The selectivity of 8 to inhibit FGFR over KDR is suggested to be caused by the difference in the interaction with M535 in FGFR1 and L889 in KDR[1]. The IC50 of CH5183284/Debio 1347 is 29 nM for FGF-dependent proliferation and 780 nM for VEGF-dependent proliferation[2].In Vivo:CH5183284 treatment shows a dose-dependent tumor regression (tumor growth inhibition (TGI)=106% at 30 mg/kg and 147% at 100 mg/kg) without apparent body weight loss. CH5183284 treatment also shows significant in vivo efficacy in xenograft mice models with FGFR genetic alterations, such as KG1 (leukemia, FGFR1OP-FGFR1 fusion), MFE280 (endometrial cancer, FGFR2 S252W mutation), UM-UC-14 (bladder cancer, FGFR3 S249C mutation), and RT112/84 (bladder cancer, FGFR3-TACC3 fusion)[1].

Protocol

Cell Assay [1]
The cell lines are added to the wells of 96-well plates containing 0.076−10,000 nM tested compounds (CH5183284) and incubated at 37°C. After 4 days’ incubation, Cell Counting Kit-8 solution is added, and after incubation for several more hours, absorbance at 450 nm is measured. The antiproliferative activity is calculated using the formula (1-T/C) × 100 (%), where T and C represent absorbance at 450 nm of the cells treated with drugs (T) and that of untreated control cells (C)[1].

Animal Administration [1][2]
Rats: Male Wistar rats (340-390 g) implanted with a telemetry transmitter are used for the assessment of effects on blood pressure (BP). Vehicle (0.5% carmellose sodium, 0.5% polysorbate 20, and 0.9% benzyl alcohol in purified water) or CH5183284/Debio 1347 (10 and 30 mg/kg) are administered by oral gavage once a day for 4 consecutive days. Data for blood pressure are automatically analyzed and continuously recorded at 5-minute intervals[2]. Mice: The in vivo efficacy is evaluated in mice bearing an SNU-16 xenograft. CH5183284 is orally administered once daily for 11 days, and the body weight of mice and the volume of the tumors are measured twice a week[1].

Discovery of [5-Amino-1-(2-methyl-3H-benzimidazol-5-yl)pyrazol-4-yl]-(1H-indol-2-yl)methanone (CH5183284/Debio 1347), An Orally Available and Selective Fibroblast Growth Factor Receptor (FGFR) Inhibitor.[Pubmed:27933954]

J Med Chem. 2016 Dec 8;59(23):10586-10600.

The fibroblast growth factor receptor (FGFR) family of receptor tyrosine kinases regulates multiple biological processes, such as cell proliferation, migration, apoptosis, and differentiation. Various genetic alterations that drive activation of the receptors and the pathway are associated with tumor growth and survival; therefore, the FGFR family represents an attractive therapeutic target for treating cancer. Here, we report the discovery and the pharmacological profiles of 8 (CH5183284/Debio 1347), an orally available and selective inhibitor of FGFR1, FGFR2, and FGFR3. The chemical modifications, which were guided by 3D-modeling analyses of the inhibitor and FGFRs, led to identifying an inhibitor that is selective to FGFR1, FGFR2, and FGFR3. In in vitro studies and xenograft models in mice, 8 shows antitumor activity against cancer cell lines that harbor genetically altered FGFRs. These results support the potential therapeutic use of 8 as a new anticancer agent.

ERK Signal Suppression and Sensitivity to CH5183284/Debio 1347, a Selective FGFR Inhibitor.[Pubmed:26438159]

Mol Cancer Ther. 2015 Dec;14(12):2831-9.

Drugs that target specific gene alterations have proven beneficial in the treatment of cancer. Because cancer cells have multiple resistance mechanisms, it is important to understand the downstream pathways of the target genes and monitor the pharmacodynamic markers associated with therapeutic efficacy. We performed a transcriptome analysis to characterize the response of various cancer cell lines to a selective fibroblast growth factor receptor (FGFR) inhibitor (CH5183284/Debio 1347), a mitogen-activated protein kinase kinase (MEK) inhibitor, or a phosphoinositide 3-kinase (PI3K) inhibitor. FGFR and MEK inhibition produced similar expression patterns, and the extracellular signal-regulated kinase (ERK) gene signature was altered in several FGFR inhibitor-sensitive cell lines. Consistent with these findings, CH5183284/Debio 1347 suppressed phospho-ERK in every tested FGFR inhibitor-sensitive cell line. Because the mitogen-activated protein kinase (MAPK) pathway functions downstream of FGFR, we searched for a pharmacodynamic marker of FGFR inhibitor efficacy in a collection of cell lines with the ERK signature and identified dual-specificity phosphatase 6 (DUSP6) as a candidate marker. Although a MEK inhibitor suppressed the MAPK pathway, most FGFR inhibitor-sensitive cell lines are insensitive to MEK inhibitors and we found potent feedback activation of several pathways via FGFR. We therefore suggest that FGFR inhibitors exert their effect by suppressing ERK signaling without feedback activation. In addition, DUSP6 may be a pharmacodynamic marker of FGFR inhibitor efficacy in FGFR-addicted cancers.

The fibroblast growth factor receptor genetic status as a potential predictor of the sensitivity to CH5183284/Debio 1347, a novel selective FGFR inhibitor.[Pubmed:25169980]

Mol Cancer Ther. 2014 Nov;13(11):2547-58.

The FGF receptors (FGFR) are tyrosine kinases that are constitutively activated in a subset of tumors by genetic alterations such as gene amplifications, point mutations, or chromosomal translocations/rearrangements. Recently, small-molecule inhibitors that can inhibit the FGFR family as well as the VEGF receptor (VEGFR) or platelet-derived growth factor receptor (PDGFR) family displayed clinical benefits in cohorts of patients with FGFR genetic alterations. However, to achieve more potent and prolonged activity in such populations, a selective FGFR inhibitor is still needed. Here, we report the identification of CH5183284/Debio 1347, a selective and orally available FGFR1, FGFR2, and FGFR3 inhibitor that has a unique chemical scaffold. By interacting with unique residues in the ATP-binding site of FGFR1, FGFR2, or FGFR3, CH5183284/Debio 1347 selectively inhibits FGFR1, FGFR2, and FGFR3 but does not inhibit kinase insert domain receptor (KDR) or other kinases. Consistent with its high selectivity for FGFR enzymes, CH5183284/Debio 1347 displayed preferential antitumor activity against cancer cells with various FGFR genetic alterations in a panel of 327 cancer cell lines and in xenograft models. Because of its unique binding mode, CH5183284/Debio 1347 can inhibit FGFR2 harboring one type of the gatekeeper mutation that causes resistance to other FGFR inhibitors and block FGFR2 V564F-driven tumor growth. CH5183284/Debio 1347 is under clinical investigation for the treatment of patients harboring FGFR genetic alterations.
