|Condition or disease||Intervention/treatment||Phase|
|Advanced Solid Tumor||Drug: SY-4798||Phase 1|
Dose-escalation phase is designed to determine the DLTs (Dose-limiting toxicity) and recommended phase II dose (RP2D) and characterize the safety, tolerability, pharmacokinetics (PK) and Pharmacodynamics (PD) of SY-4798. Other dose regimens may be explored based on the analysis of emerging PK and safety data. At this study phase, SY-4798 will be administered orally once daily (QD) in 28-day treatment cycles to adult patients with advanced solid tumor.
Dose-expansion phase is designed to evaluate the anti-tumor activity (ORR and DOR) of SY-4798 in patients with FGF19+ advanced tumor.
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||80 participants|
|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Official Title:||A Phase I, Open-Label, Multi-Center, Dose-escalation/ Dose-expansion Study to Evaluate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics and Preliminary Anti-Tumor Activity of SY-4798 Tablet in Patients With Advanced Solid Tumor|

Experimental: Dose-escalation and Dose-expansion
SY-4798 will be given orally in ascending doses (escalation cohort) until the DLT or RP2D is reached. In dose-expansion phase, preliminary anti-tumor activity will be assessed in FGF19+ advanced tumor.
