| Phase 1/Phase 2 |
Detailed Description
This study is a multi-center, open labeled, single, -combined, with multiple dose escalation trial.
The trial consists of dose escalation phase and dose expansion phase; Dose escalation phase:
based on the earlier studies, 3 more patients will be added to the 180mg/m2 dose group. The follow-up dose group will adopt the "3+3" design, with 3-6 subjects in each group; include 3 preset dose levels, 220mg/m2, 260mg/m2 and 300mg/m2, respectively. Each subject will receive only one corresponding dose. After the completion of single dose and 21-day DLT observation period, Safety is assessed by the investigator and sponsor, and if the safety evaluation results is favorable, subject will continue to receive the same level of testing compound. Each patient will receive maximum of 4 cycle of treatments.
Dose expansion stage: according to the results of the dose increasing stage, dose groups will be selected for expansion. It is expected that 2 to 3 dose groups will enter the expansion stage, and the total number of participants in each dose group will be 20, and a total of 4 cycles of drug administration will be given to each subject.

Outcome Measures
Primary Outcome Measures
- To determine dose limited toxicity (DLT) of JK-1201I in patients with SCLC. [21days]
Dose limited toxicity in SCLC patients will be determined. DLT is defined as: 1..Grade 4 neutropenia (ANC) reduction lasts ≥3 days; or grade 3 ANC reduction with fever (ANC <1000 / mm3 with oral temperature single measurement> 38.3 ℃ or ≥38.0 ℃ for 1 hour)； 2. Grade 3 thrombocytopenia (25×109/L≤ platelet count < 50×109/L) with obvious clinical bleeding symptoms, or grade 4 thrombocytopenia (with or without obvious clinical bleeding symptoms); 3. Other grade 4 hematological toxicity； 4. Grade 3 and above non-hematological toxicity； 5. Hair loss, fatigue, except for those with grade 3 nausea, vomiting, and diarrhea without maximum symptomatic supportive treatment.
- To determine the maximum tolerance dose level of JK-1201I in patients with SCLC. [21days]
MTD is defined as the highest dose that can be given without causing any adverse side effects according to CTCAE v5.0.
Secondary Outcome Measures
- To measure the highest plasma concentrations of JK-1201I in patients with SCLC. [21 days]
The maximum concentration (Cmax) will be measured and compared across different groups.
- To determine the exposure levels of JK-1201I in SCLC patients [21 days]
The area under the plasma concentration versus time curve（AUC）will be compared across different groups.
- To examine the primary efficacy of JK-1201I in treating patients with SCLC. [21days]
Evaluation Criteria In Solid Tumors (RECIST v1.1) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), at least a 30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.
