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.
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. ⋯ 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.
