Description: Capmatinib, also known as INCB28060 and INC280, is an orally bioavailable inhibitor of the proto-oncogene c-Met (hepatocyte growth factor receptor [HGFR]) with potential antineoplastic activity. c-Met inhibitor INC280 selectively binds to c-Met, thereby inhibiting c-Met phosphorylation and disrupting c-Met signal transduction pathways. This may induce cell death in tumor cells overexpressing c-Met protein or expressing constitutively activated c-Met protein. Capmatinib was approved in 2020.

Biological target: ATP competitive c-Met kinase inhibitor (IC50=0.13 nM)
In vitro activity: Pancreatic cancer is characterized by a strong stromal reaction. Therefore, the effects of cMET inhibition on ECs and VSMCs were examined. MTT assays in ECs under serum-starved conditions and stimulation with HGF, showed a slight but significant increase in growth that was diminished by INC280 (Capmatinib) (Additional file 3: Figure S3B). No effect upon constitutive conditions was observed (Additional file 3: Figure S3A). EC motility was significantly increased upon incubation with HGF, which was strongly reduced by INC280 (Figure 4A). Regarding activation of signaling pathways, treatment with INC280 strongly inhibited HGF-induced activation of Akt and ERK whereas no effects on constitutive Akt and ERK phosphorylation were found (Figure 4B). Taken together, these results show that INC280 affects ECs only when these cells are stimulated with HGF. Next we analyzed the impact of INC280 on VSMCs. MTT assays showed a dose-dependent inhibition of VSMC growth starting from INC280 (100nM) after 72 hours of incubation (Additional file 3: Figure S3C). In contrast to ECs, stimulation with HGF upon serum-starved conditions had no effect on VSMC growth and, accordingly, INC280 did not have a further growth inhibitory effect in MTT assays (Additional file 3: Figure S3D). Motility upon incubation with HGF in VSMCs was not induced, but targeting cMET with INC280 led to a significant inhibition of constitutive migration (Figure 4C). Finally, Western blotting did not show a substantial effect of INC280 on constitutive Akt phosphorylation and only a minor impact on ERK phosphorylation in VSMCs (Figure 4D). These results indicate that HGF does not affect VSMCs and cMET inhibition with INC280, therefore, has only minor effects on these cells. Reference: BMC Cancer. 2015; 15: 71.
In vivo activity: Tumors underwent a histological examination by a pathologist to determine phenotype and progression. Of the WT mice fed normal diet there were a total of 16 tumors. Twelve of the tumors were papillomas, with one converting to a squamous cell carcinoma (Fig.4d). Three additional tumors were cutaneous lipomas. This is in comparison to Tpl2 −/− mice which had a total of 61 tumors, 51 papillomas, four SCCs, three sebaceous adenomas, and three lipomas. In contrast, no Tpl2 −/− mice fed capmatinib diet had papillomas convert to SCCs (Fig. (Fig.4d).4d). Although Tpl2 −/− mice develop an overall higher tumor burder, there were no statistical differences in tumor size between genotypes and the rate of malignant conversion (7.8 vs. 8.3%) was similar between Tpl2 −/− and WT mice on normal diet. However, the rate of malignant conversion between Tpl2 −/− mice on normal diet (8.3%) vs. Tpl2 −/− mice on Capmatinib diet (0%) was significantly different (p < 0.01). In both genotypes male mice developed more tumors than female mice (Fig.4e; p < 0.05). Reference: Oncogenesis. 2019 Jan; 8(1): 1.

Additional Information

INCB28060 exhibits picomolar enzymatic potency and is highly specific for c-MET with more than 10,000-fold selectivity over a large panel of human kinases. This inhibitor potently blocks c-MET phosphorylation and activation of its key downstream effectors in c-MET-dependent tumor cell lines. As a result, INCB28060 potently inhibits c-MET-dependent tumor cell proliferation and migration and effectively induces apoptosis in vitro. Oral dosing of INCB28060 results in time- and dose-dependent inhibition of c-MET phosphorylation and tumor growth in c-MET-driven mouse tumor models, and the inhibitor is well tolerated at doses that achieve complete tumor inhibition. In a further exploration of potential interactions between c-MET and other signaling pathways, we found that activated c-MET positively regulates the activity of epidermal growth factor receptors (EGFR) and HER-3, as well as expression of their ligands. These effects are reversed with INCB28060 treatment. Finally, we confirmed that circulating hepatocyte growth factor levels are significantly elevated in patients with various cancers. Activated c-MET has pleiotropic effects on multiple cancer-promoting signaling pathways and may play a critical role in driving tumor cell growth and survival. INCB28060 is a potent and selective c-MET kinase inhibitor that may have therapeutic potential in cancer treatment. (source: Clin Cancer Res; 17(22); 7127-38. ©2011 AACR.)
