Outcome Measures
Primary Outcome Measures

- Severity of adverse events (AE) [Up to 34 months.]
Severity of AE evaluated by CTCAE 5.0 (Common Terminology Criteria for Adverse Events 5.0).
- Incidence of serious adverse events (SAE) [Up to 34 months.]
Incidence of SAE evaluated by CTCAE 5.0 (Common Terminology Criteria for Adverse Events 5.0).
- Severity of serious adverse events (SAE) [Up to 34 months.]
Severity of SAE evaluated by CTCAE 5.0 (Common Terminology Criteria for Adverse Events 5.0).
- Incidence of abnormal laboratory examination indexes. [Up to 34 months.]
Incidence of abnormal laboratory examination indexes evaluated by CTCAE 5.0 (Common Terminology Criteria for Adverse Events 5.0).
- Severity of abnormal laboratory examination indexes. [Up to 34 months.]
Severity of abnormal laboratory examination indexes evaluated by CTCAE 5.0 (Common Terminology Criteria for Adverse Events 5.0).
- Recommended phase II dose (RP2D) [Up to 18 months]
To determine the recommended phase II dose of TQB3909 tablets in the treatment of recurrent or refractory CLL/SLL.
- Objective remission rate (ORR) determined by Independent Review Committee (IRC) [Up to 34 months]
Determine the objective remission rate (ORR) based on the evaluation results of the Independent Review Committee (IRC), defined as the proportion of subjects whose best remission is complete remission (CR) and partial remission (PR).
Secondary Outcome Measures
- Objective remission rate (ORR) determined by the investigators' evaluation. [Up to 34 months]
The objective remission rate (ORR) was determined by the results of the investigator s' evaluation, defined as the proportion of subjects whose best remission is complete remission (CR) and partial remission (PR).
- Duration of remission (DOR) [Up to 34 months]
For all subjects whose best response was PR, CR,, the time from the date of first achieving PR, CR to the date of first definite disease progression or death from any cause (whichever occurs first).
- Time to disease progression (TTP) [Up to 34 months]
Refers to the time from the first medication to the objective progress of the disease.
- Time to remission (TTR) [Up to 34 months]
Time from the beginning of treatment to the first recording of remission (PR or better remission), only the remission population was analyzed.
- Progression-free survival (PFS) [Up to 34 months]
The time from the first medication to the objective progression of the disease or death caused from any cause (whichever comes first).
- Overall survival (OS) [Up to 34 months]
Time from first dose of study drug to date of death from any cause.
- Time to reach maximum concentration (Tmax) [Within 120 hours after administration]
Time to reach maximum plasma concentration after single and multiple dosing of TQB3909 tablets.
- Maximum plasma drug concentration (Cmax) [Within 120 hours after administration]
Cmax is the maximum plasma concentration of TQB3909.
- Area under the plasma concentration-time curve (AUC0-t) [Within 120 hours after administration]
To characterize the pharmacokinetics of TQB3909 by assessment of area under the plasma concentration time curve.
- Plasma elimination half-life (t1/2) [Within 120 hours after administration]
t1/2 is time it takes for the blood concentration of TQB3909 to drop by half.
- Undetectable measurable residual disease (U-MRD) ratio of peripheral blood and/or bone marrow. [Up to 34 months]
Refers to the undetected residual lesions. Peripheral blood and/or bone marrow are used to detect less than 1 CLL cell (less than 10-4) in 10000 white blood cells by flow cytometry.
- Correlation between potential biomarkers and TQB3909 tablets. [Up to 34 months]
Correlation of potential biomarkers with TQB3909 tablets: such as BTK and PLCG2 mutation status and allele frequency.
