A Phase 1 Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Efficacy of GH2616 in Subjects With Advanced Solid Tumor.

brief summary

GH2616 is a potent and selective inhibitor targeting KIF18A, exhibiting distinct and superior anticancer properties compared to other cell cycle and anti-mitotic drug targets, with significant inhibitory effects on TP53 mutant and WGD (whole genome doubling) or CIN (chromosomal instability) tumors. GH2616 regulates chromosome distribution and alignment, prolongs mitotic duration, and activates the spindle assembly checkpoint by inhibiting KIF18A activity, thereby arresting mitosis at the G2/M phase, inducing mitotic catastrophe, and ultimately achieving tumor suppression. This study will evaluate the safety and tolerability of GH2616 in patients with advanced solid tumors, and determine its dose-limiting toxicity (DLT), maximum tolerated dose (MTD), and/or recommended phase II dose (RP2D).
