Phase I : Incidence, type, and severity of adverse events (AEs) as judged according to NCI-CTCAE V5.0
AE refers to any adverse event occurring in subjects during clinical research period. The incidence and type of AEs will be evaluated and the severity will be judged according to National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) Version5.0.
Time frame: Through study completion, an average of 3 years
Phase I : Incidence, type, and severity of dose-limiting toxicities (DLTs)
The dose-limiting toxicity (DLT) assessed in the phase I dose exploration study is defined as AEs related to study treatment that meet the following criteria (according to the NCI CTCAE v5.0 criteria) and occur in Cycle 1.
Time frame: Through study completion, an average of 3 years
Phase I : RP2Ds and/or MTDs
Phase I is the dose exploration study of ICP-490 to preliminarily determine RP2Ds (probably more than one) and MTD (if applicable). MTD: The dose level corresponding to the dose group whose posterior probability of DLT incidence estimated by PAVA (pool adjacent violators algorithm) is closest to the target toxicity probability (25%).
Time frame: Through study completion, an average of 3 years
Phase II : ORR (defined as sCR + CR + VGPR + PR) assessed according to IMWG criteria.
Disease response will be assessed according to the 2016 IMWG response criteria.
Time frame: Through study completion, an average of 3 years
Maximum concentration (Cmax)
Maximum concentration (Cmax) will be calculated through multiple plasma concentrations drawn from the patients after administration.
Time frame: Through study completion, an average of 3 years
