A Study of SYHA1807 in Subjects With Extensive-Stage Small Cell Lung Cancer
- Registration Number
- NCT04404543
- Lead Sponsor
- CSPC ZhongQi Pharmaceutical Technology Co., Ltd.
- Brief Summary
This is a phase I, open-label, multi-center, non-randomized, 2-part first time inhuman (FTIH) study for SYHA1807. Part 1 is a dose escalation phase to determine the recommended phase 2 dose (RP2D) for SYHA1807 based on the safety, tolerability and pharmacokinetics (PK) profiles observed after oral administration of SYHA1807. The dose escalation study will be performed according to the 3+3 design. Once RP2D is identified, an expansion cohort (Part 2) of up to 12\~40 subjects will be enrolled to further evaluate the clinical activity and tolerability of SYHA1807 in subjects with extensive-stage Small Cell Lung Cancer (SCLC).

Group Intervention Description Dose Expansion Cohort SYHA1807 Once the RP2D has been determined, an expansion cohort of up to 12\~40 subjects will be enrolled in order to better characterize the clinical activity and safety profile of the RP2D. Escalation Cohort SYHA1807 Five dose levels will be tested according to the "3 + 3" dose-escalation design. The dose-limiting toxicity (DLT) will be assessed from the first administration of SYHA1807 to the end of the first cycle (28 days).
- Primary Outcome Measures
Name Time Method Number of Participants Withdrawn Due to Toxicities Through study completion, an average of 2 year Participants were monitored from start of the study till the development of toxicity. The data for number of participants withdrawn due to toxicities has been presented.
Number of Participants With Dose Reduction or Delays Through study completion, an average of 2 year The number of participants who had any dose reduction or delay have been presented. All dose reductions were due to AEs.
Number of Participants With Change in Clinical Chemistry Toxicity Grade From Baseline Through study completion, an average of 2 year Baseline value was defined as the most recent, non-missing value from a central laboratory prior to or on the first dose of study treatment. Change from Baseline was defined as any visit value minus Baseline value. The number of participants with any grade increase in hematology parameters have been presented.
Number of Participants With Critical Changes in Values of Vital Signs in Response to Drug Through study completion, an average of 2 year Vital sign measurements includes systolic blood pressure (SBP), diastolic blood pressure (DBP), temperature, respiration rate and heart rate. The number of participants with critical changes in values of vital signs in response to drug have been presented.
Part 1:Number of Participants With Adverse Events Through study completion, an average of 2 year An AE is any untoward medical occurrence in a clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.
Part 1:Number of Participants With Serious Adverse Events (SAEs) Through study completion, an average of 2 year SAE is defined as any untoward medical occurrence that, at any dose results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability, is a congenital anomaly/birth defect, other situations and is associated with liver injury or impaired liver function.
Part 1:Number of Participants With Dose Limiting Toxicities (DLT) Through study completion, an average of 2 year An event was considered a DLT if it occurs within the first 28 days of treatment.
- Secondary Outcome Measures
Name Time Method Time to Reach Cmax (Tmax) Following Single and Repeat Dose Administration of SYHA1807 Through study completion, an average of 2 year The analysis was performed on Pharmacokinetic Population which included all participants in the All Treated Population for whom a pharmacokinetic sample was obtained and analyzed. Tmax is the time to reach Cmax, determined directly from the concentration-time data.
Area Under the Concentration-time Curve From Time Zero (Pre-dose) Extrapolated to Infinite Time (AUC [0-infinity]) Following Single Dose Administration of SYHA1807 Through study completion, an average of 2 year The analysis was performed on Pharmacokinetic Population which included all participants in the All Treated Population for whom a pharmacokinetic sample was obtained and analyzed.
Apparent Terminal Phase Elimination Rate Constant (λz) Following Single and Repeat Dose Administration of SYHA1807 Through study completion, an average of 2 year The analysis was performed on Pharmacokinetic Population which included all participants in the All Treated Population for whom a pharmacokinetic sample was obtained and analyzed.
Maximum Observed Plasma Concentration (Cmax) Following Single and Repeat Dose Administration of SYHA1807 Through study completion, an average of 2 year The analysis was performed on Pharmacokinetic Population which included all participants in the All Treated Population for whom a pharmacokinetic sample was obtained and analyzed.
Number of Participants Achieving Disease Control Rate at Week 6、12 Through study completion, an average of 2 year Clinical response was assessed by the investigator using computer tomography or magnetic resonance imaging scans. Clinical response was defined as disease control rate ,CR(Complete response)+PR(Partial response)+SD(Stable disease),based on RECIST version 1.1 at Week 6、12.
Apparent Terminal Phase Half-life (T1/2) Following Single and Repeat Dose Administration of SYH1A1807 Through study completion, an average of 2 year The analysis was performed on Pharmacokinetic Population which included all participants in the All Treated Population for whom a pharmacokinetic sample was obtained and analyzed.
