Arms and Interventions

Arm	Intervention/Treatment
Experimental: HS-10386 Participants will receive HS-10386 once daily. The duration of each treatment cycle is 21 days.	Drug: HS-10386 Starting dose 10 mg, administered once daily. If tolerated, subsequent cohorts will test increasing doses of HS-10386, until a maximum tolerated dose (MTD) or maximum applicable dose (MAD) is defined

Arm

Intervention/Treatment

Experimental: HS-10386

Participants will receive HS-10386 once daily. The duration of each treatment cycle is 21 days.

Drug: HS-10386

Starting dose 10 mg, administered once daily. If tolerated, subsequent cohorts will test increasing doses of HS-10386, until a maximum tolerated dose (MTD) or maximum applicable dose (MAD) is defined

Outcome Measures

Primary Outcome Measures

Maximum Tolerated Dose (MTD) or Maximum Applicable Dose (MAD) (Dose Escalation Phase) [Up to 21 days from the first dose]
MTD is defined as the dose level immediately below that at which 2 or more patients exhibit dose limiting toxicity. MAD is defined as the maximum administered dose, when MTD is not reached.
Objective Response Rate (ORR) defined by Response Evaluation Criteria in Solid Tumors (RECIST 1.1) (Dose Expansion Phase) [Every 6 weeks for the duration of study participation; estimated to be 12 months.]
ORR is defined as the percentage of patients who have at least 1 response of CR or PR prior to any evidence of progression.

Secondary Outcome Measures

Incidence and Severity of Adverse Events (AEs) [From Informed consent until the end of the follow-up period which is defined as 28 days (+7 days) after study treatment is discontinued.]
The number and percentage of patients that experience an AE. The severity of AEs are assessed according to the NCI Common Terminology Criteria for Adverse Events (CTCAE), Version 5.0.
Cmax of HS-10386 [Approximately 1 month.]
Cmax is defined as the maximum observed plasma or serum concentration.
Tmax of HS-10386 [Approximately 1 month.]
Tmax is defined as the time to maximum concentration.
λz of HS-10386 [Approximately 1 month.]
λz is defined as the apparent terminal-phase disposition rate constant.
t1/2 of HS-10386 [Approximately 1 month.]
t1/2 is defined as the apparent terminal-phase disposition half-life.
AUC0-t of HS-10386 [Approximately 1 month]
AUC0-t is defined as the area under the plasma or serum concentration-time curve from time = 0 to the last measurable concentration at time = t.
CL/F of HS-10386 [Approximately 1 month.]
CL/F is defined as the apparent oral dose clearance.
ORR defined by Response Evaluation Criteria in Solid Tumors (RECIST 1.1) (Dose Escalation Phase) [Every 6 weeks for the duration of study participation; estimated to be 12 months.]
ORR is defined as the percentage of patients who have at least 1 response of CR or PR prior to any evidence of progression.
Disease Control Rate (DCR) [Every 6 weeks for the duration of study participation; estimated to be 12 months.]
The DCR is defined as the percentage of patients with a best overall response of CR, PR, or SD.
Duration of Response (DoR) [Every 6 weeks for the duration of study participation; estimated to be 12 months.]
DoR is defined as the time from the date of first documented response until the date of documented progression or death in the absence of disease progression.
Progression-Free Survival (PFS) [Every 6 weeks for the duration of study participation; estimated to be 12 months.]
PFS was defined as the time from random assignment (dose expansion stage) or first dose (dose escalation stage) to PD or death from any cause.
Overall Survival (OS) (Dose Expansion Phase) [From the time of randomization to death due to any cause, approximately 3 years.]
OS is deﬁned as the time from randomization to death due to any cause.
The correlation between PD-L1 expression and efficacy of HS-10386 [Approximately 3 years.]
The study will collect tumor tissue samples during screening period and after the treatment. Stratified analysis of the efficacy endpoint of HS-10386 (such as object response, DoR, PFS, etc.) by PD-L1 expression level will be performed to assess the correlation between PD-L1 expression as biomarker and study dose and effeicacy of HS-10386.
