Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| To determine the maximum tolerated dose (MTD)-Part Ia | From the single dose to the last dose of the first cycle defined as 21 days of multiple dosing (28 days) | Number of participants with dose limiting toxicity |
| To evaluate clinical activity/efficacy of HS-10375 by assessment of objective response rate-Part Ib/II | Time Frame: up to 24 months | Objective response rate (ORR) assessed by Response Evaluation Criteria in Solid Tumors 1.1 (RECIST 1.1) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time to reach maximum plasma concentration (Tmax) after single dose of HS-10375 | From pre-dose to 120 hours after single dose on Day 1 | In the study of single-dose, Tmax will be obtained following administration of a single oral dose of HS-10375 |
| Apparent terminal half-life (T1/2) after single dose of HS-10375 | From pre-dose to 120 hours after single dose on Day 1 | Apparent terminal half-life is the time measured for the concentration to decrease by one half. Terminal half-life calculated by natural log 2 divided by λz |
| Duration of response (DOR) | 24 months | DOR assessed by RECIST 1.1 criteria |
| Number of participants with treatment related adverse events | From baseline until 28 days after the last dose | Number of participants with treatment related adverse events |
| Progression-free survival (PFS) | 24 months | PFS assessed by RECIST 1.1 criteria |
| Overall survival (OS) | 24 months | — |
| Disease Control Rate (DCR) | 24 months | DCR assessed by RECIST 1.1 criteria |
| Observed maximum plasma concentration (Cmax) after single dose of HS-10375 | From pre-dose to 120 hours after single dose on Day 1 | In the study of single-dose, Cmax will be obtained following administration of a single oral dose of HS-10375 |
