Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Adverse events (AEs). | From the first drug administration to within 30 days for the last treatment dose, up to 24 months. |
| Serious adverse events (SAEs). | From the first drug administration to within 30 days for the last treatment dose, up to 24 months. |
| Dose-limiting toxicity (DLT) of SHR-4685. | Up to 21 days. |
| Maximum tolerated dose (MTD) of SHR-4685. | Up to 24 months. |
| Recommended Phase II Dose (RP2D) of SHR-4685. | Up to 24 months. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The concentration of SHR-4685 in plasma will be determined. | At predefined intervals throughout the treatment period, up to 24 months. | Cmax will be derived. |
| Time to maximum concentration (Tmax). | At predefined intervals throughout the treatment period, up to 24 months. | Evaluation of pharmacokinetic parameter of SHR-4685. |
| Duration of response (DoR). | Up to 24 months. | Time from documentation of tumor response to disease progression assessed among patients who had an objective response. |
| Area under the concentration-time curve from time 0 to time t (time of the last measurable concentration) (AUC0-t). | At predefined intervals throughout the treatment period, up to 24 months. | Evaluation of pharmacokinetic parameter of SHR-4685. The concentration of SHR-4685 in plasma will be determined. Area under the curve is the integral of the concentration-time curve. The AUC reflects the actual body exposure to drug after administration. The AUC is dependent on the rate of elimination of the drug from the body and the dose administered. |
| Progression Free Survival (PFS). | Up to 24 months. | Time from C1D1 to first assessment of disease progression or death, whichever is earlier. |
| Objective Response Rate (ORR). | Up to 24 months. | Complete Response (CR) and Partial Response (PR) based on RECIST 1.1. |
| Disease control rate (DCR). | Up to 24 months. | Complete Response (CR), Partial Response (PR) and Stable Disease (SD) based on RECIST 1.1. |
| The concentration of Anti-SHR-4685 antibodies (ADA) in plasma will be determined. | At predefined intervals throughout the treatment period, up to 24 months. | — |
