Brief summary
This phase Ib/II clinical trial studies the safety and effect of Gimatecan in small cell lung cancer patients who failed the first-line standard platinum-containing chemotherapy. The chemotherapy will be given every four weeks.
Interventions

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Dose limited toxicity (DLT) | up to 28 days. | Phase Ib: Number of patients experienced any dose limited toxicity over the DLT period. |
| Recommended phase II dose (RP2D) | up to 12 months. | Phase Ib: Determination of recommended phase II dose of escalating dose of gimatecan for the phase II part of the study. |
| Objective response rate (ORR) | To evaluate objective response rate every 8 weeks after the initiation of chemotherapy, up to 24 months. | Percentage of patients with objective response assessed by best overall response (BOR) of either complete response(CR) or partial remission(PR) will be reported. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Overall survival (OS) | From date of randomization until the date of death from any cause or the date of last follow-up whichever came first, assessed up to 24 months. | The 2-year overall survival of the whole group. |
| Progression free survival (PFS) | From date of randomization until the date of death from any cause or the date of first documented disease progression whichever came first, assessed up to 24 months. | The 2-year progression free survival of the whole group. |
| Treatment related adverse events rate | From the enrollment to 30 days later of the last chemotherapy. | The incidence rate of treatment related adverse events of the whole group assessed by CTCAE v5.0. |
| Survival rate (SR) | up to 24 months. | Survival probability of patients calculated according to Kaplan-Meier curve at either 1 or 2 year. |
| Disease control rate (DCR) | To evaluate disease control rate every 8 weeks after the initiation of chemotherapy, up to 24 months. | Percentage of patients with disease control as assessed by best overall response (BOR) of either complete response(CR), partial remission(PR) or stable disease (SD) will be reported. |
| Duration of Response (DoR) | First documented CR or PR, whichever is first recorded until the first assessment of PD, assessed up to 24 months. | The DoR applies only to patients whose BOR is either CR or PR. The duration is measured from the first documented response (CR or PR, whichever is first recorded) until the first assessment of Progressive Disease (PD). |
