Arm && Interventions

Group	Intervention	Description
AK-1286	AK-1286	After a screening period of approximately 28 days, eligible patients will receive oral YL-15293 once or twice daily until documented disease progression, unacceptable AEs, intercurrent illness prevents further administrations of study treatment, investigator's decision to withdraw the patient, the patient withdraws consent, pregnancy of the patient, or for administrative reasons. Following the end of treatment, patients will continue to be followed for safety for 30 days. Patients who permanently discontinue study treatment for reasons other than disease progression will have post-treatment follow-up for disease assessment until start of new anticancer treatment, patient withdraws consent, is lost to follow-up, death, or until the Sponsor stops the study, whichever comes first.

Primary Outcome Measures

Name	Time	Method
Occurrence of drug limited toxicities (DLTs)	From Time of First dose through DLT observation period, 21 days	To assess by the occurrence of Drug Limited Toxicities (DLTs)
Incidence of Treatment-emergent adverse event (TEAEs) and serious adverse events (SAEs)	From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 60 months	To assess by the occurrence of Treatment-emergent adverse event (TEAEs) and serious adverse events (SAEs)
Number of patients with changes in laboratory parameters from baseline	From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 60 months	To assess safety of AK-1286
Number of participants with changes in clinically significant vital sign from baseline	From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 60 months	To assess safety of AK-1286

Secondary Outcome Measures

Name	Time	Method
The overall response rate (ORR)	From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 60 months	The overall response rate (ORR) will be estimated based on the proportion of evaluable patients whose overall response (ORR) during study treatment is CR or PR. Disease response will be assessed by the investigator using RECIST v1.1.response (ORR) during study treatment is CR or PR. Disease response will be assessed by the investigator using RECIST v1.1
Progression free survival（PFS）	From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 60 months	PFS, defined as the time from the first dose of study treatment to The tumor progresses for the first time
Overall survival（OS）	From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 60 months	The time from randomization to death for any reason
Disease control rate（DCR）	From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 60 months	The percentage of cases with remission (PR+CR) and stable lesions (SD) after treatment
