ASP5878 inhibits the cell proliferation of HCC cell lines expressing FGF19. ASP5878 inhibits FGFR4 phosphorylation and its treatment results in the suppression of phosphorylation, mobility shift of FRS2, and suppression of ERK phosphorylation in Hep3B2.1-7 cells[1].
Oral administration of ASP5878 at 3 mg/kg induces sustained tumor regression in a subcutaneous xenograft mouse model using Hep3B2.1-7. In HuH-7, an orthotopic xenograft mouse model, ASP5878 induces complete tumor regression and dramatically extended the survival of the mice[1].

ASP5878, a Novel Inhibitor of FGFR1, 2, 3, and 4, Inhibits the Growth of FGF19-Expressing Hepatocellular Carcinoma
Mol Cancer Ther 2017 Jan;16(1):68-75.PMID:27837028DOI:10.1158/1535-7163.MCT-16-0188.
Hepatocellular carcinoma is an aggressive cancer with poor prognosis. Fibroblast growth factor 19, a member of the fibroblast growth factor family, is a ligand for fibroblast growth factor receptor 4. Moreover, it plays a crucial role in the progression of hepatocellular carcinoma. ASP5878 is a novel inhibitor of fibroblast growth factor receptors 1, 2, 3, and 4 that is under development. It inhibits fibroblast growth factor receptor 4 kinase activity with an IC50 of 3.5 nmol/L. ASP5878 potently suppressed the growth of the fibroblast growth factor 19-expressing hepatocellular carcinoma cell lines Hep3B2.1-7, HuH-7, and JHH-7. In the Hep3B2.1-7 cell line, ASP5878 inhibited the phosphorylation of fibroblast growth factor receptor 4 and its downstream signaling molecules as well as induced apoptosis. Oral administration of ASP5878 at 3 mg/kg induced sustained tumor regression in a subcutaneous xenograft mouse model using Hep3B2.1-7. In HuH-7, an orthotopic xenograft mouse model, ASP5878 induced complete tumor regression and dramatically extended the survival of the mice. These results suggest that ASP5878 is a potentially effective therapeutic agent for hepatocellular carcinoma patients with tumors expressing fibroblast growth factor 19.

Discovery of ASP5878: Synthesis and structure-activity relationships of pyrimidine derivatives as pan-FGFRs inhibitors with improved metabolic stability and suppressed hERG channel inhibitory activity
Bioorg Med Chem 2022 Apr 1;59:116657.PMID:35219181DOI:10.1016/j.bmc.2022.116657.
Fibroblast growth factor receptor 3 (FGFR3) is an attractive therapeutic target for the treatment of bladder cancer patients harboring genetic alterations in FGFR3. We identified pyrimidine derivative ASP5878 (27) with improved metabolic stability and suppressed human ether-á-go-go related gene (hERG) channel inhibitory activity by the optimization of lead compound 1. Based on prediction of the metabolites of 1, an ether linker was introduced in place of the ethylene linker to improve metabolic stability. Moreover, conversion of the phenyl moiety into the pyrazole ring resulted in the suppression of hERG channel inhibitory activity, possibly due to the weaker π-π stacking interaction with Phe656 in the hERG channel by a reduction in π-electrical density of the aromatic ring. ASP5878 showed potent in vitro FGFR3 enzyme and cell growth inhibitory activity, and in vivo FGFR3 autophosphorylation inhibitory activity. Moreover, ASP5878 did not affect the hERG current up to 10 µM by in vitro patch-clamp assay, and a single oral dose of ASP5878 at 1, 10, and 100 mg/kg did not induce serious adverse effects on the central nervous, cardiovascular, and respiratory systems in dogs. Furthermore, ASP5878 exhibited lower total clearance than hepatic blood flow and high oral bioavailability in rats and dogs, and moderate brain penetration in rats.
Evaluation of FGFR inhibitor ASP5878 as a drug candidate for achondroplasia
Sci Rep 2020 Dec 1;10(1):20915.PMID:33262386DOI:10.1038/s41598-020-77345-y.
Achondroplasia is caused by gain-of-function mutations in FGFR3 gene and leads to short-limb dwarfism. A stabilized analogue of C-type natriuretic peptide (CNP) is known to elongate bone by interacting with FGFR3 signals and thus is a promising drug candidate. However, it needs daily administration by percutaneous injection. FGFR inhibitor compounds are other drug candidates for achondroplasia because they directly fix the mutant protein malfunction. Although FGFR inhibitors elongate the bone of model mice, their adverse effects are not well studied. In this study, we found that a new FGFR inhibitor, ASP5878, which was originally developed as an anti-cancer drug, elongated the bone of achondroplasia model male mice at the dose of 300 μg/kg, which confers an AUC of 275 ng·h/ml in juvenile mice. Although ASP5878 was less effective in bone elongation than a CNP analogue, it is advantageous in that ASP5878 can be administered orally. The AUC at which minimal adverse effects were observed (very slight atrophy of the corneal epithelium) was 459 ng·h/ml in juvenile rats. The positive discrepancy between AUCs that brought efficacy and minimal adverse effect suggests the applicability of ASP5878 to achondroplasia in the clinical setting. We also analyzed effects of ASP5878 in a patient-specific induced pluripotent stem cell (iPSC) model for achondroplasia and found the effects on patient chondrocyte equivalents. Nevertheless, cautious consideration is needed when referring to safety data obtained from its application to adult patients with cancer in clinical tests.
ASP5878, a selective FGFR inhibitor, to treat FGFR3-dependent urothelial cancer with or without chemoresistance
Cancer Sci 2017 Feb;108(2):236-242.PMID:27885740DOI:10.1111/cas.13124.
FGF/FGFR gene aberrations such as amplification, mutation and fusion are associated with many types of human cancers including urothelial cancer. FGFR kinase inhibitors are expected to be a targeted therapy for urothelial cancer harboring FGFR3 gene alternations. ASP5878, a selective inhibitor of FGFR1, 2, 3 and 4 under clinical investigation, selectively inhibited cell proliferation of urothelial cancer cell lines harboring FGFR3 point mutation or fusion (UM-UC-14, RT-112, RT4 and SW 780) among 23 urothelial cancer cell lines. Furthermore, ASP5878 inhibited cell proliferation of adriamycin-resistant UM-UC-14 cell line harboring MDR1 overexpression and gemcitabine-resistant RT-112 cell line. The protein expression of c-MYC, an oncoprotein, in gemcitabine-resistant RT-112 cell line was higher than that in RT-112 parental cell line and ASP5878 decreased the c-MYC expression in both RT-112 parental and gemcitabine-resistant RT-112 cell lines. Once-daily oral administration of ASP5878 exerted potent antitumor activities in UM-UC-14, RT-112 and gemcitabine-resistant RT-112 xenograft models without affecting body weight. These findings suggest that ASP5878 has the potential to be an oral targeted therapy against urothelial cancer harboring FGFR3 fusion or FGFR3 point mutation after the acquisition of gemcitabine- or adriamycin-resistance.
A phase 1 study of oral ASP5878, a selective small-molecule inhibitor of fibroblast growth factor receptors 1-4, as a single dose and multiple doses in patients with solid malignancies
Invest New Drugs 2020 Apr;38(2):445-456.PMID:31041575DOI:10.1007/s10637-019-00780-w.
ASP5878 is a selective small-molecule inhibitor of fibroblast growth factor receptors (FGFRs). This study investigated safety, tolerability, and antitumor effect of single and multiple oral doses of ASP5878 in patients with solid tumors. This phase 1, open label, first-in-human study comprised dose-escalation and dose-expansion parts. Primary objectives of the dose-escalation part were to identify the dose-limiting toxicity (DLT), maximum tolerated dose, and recommended dose of ASP5878 for the dose-expansion part. Nine dose cohorts of ASP5878 were evaluated (0.5─2 mg once daily; 2─40 mg twice daily [BID]). A single dose of ASP5878 was followed by a 2-day pharmacokinetic collection, and then either 28-day cycles of daily dosing (ASP5878 ≤ 10 mg BID) or 5-day dosing/2-day interruption (ASP5878 ≥ 20 mg BID). The primary objective of the dose-expansion part was to determine the safety of ASP5878 (16 mg BID) administered in 28-day cycles of 5-day dosing/2-day interruption in patients with urothelial carcinoma, hepatocellular carcinoma, or squamous cell lung carcinoma with FGFR genetic alterations. Safety was assessed by monitoring adverse events (AEs). Thirty-five patients were enrolled and 31 discontinued in the dose-escalation part; 51 patients were enrolled and 51 discontinued in the dose-expansion part. In the dose-escalation part, 66.7% of patients in the 20 mg BID 5-day dosing/2-day interruption group reported DLTs of hyperphosphatemia. The recommended dose for the dose-expansion part was 16 mg BID. Common AEs included retinal detachment, diarrhea, and increased alanine aminotransferase. One death occurred that was not related to ASP5878. ASP5878 was well tolerated with manageable toxicities including hyperphosphatemia.
