TQB2223 Injection in Combination With Penpulimab in Patients With Advanced Cancers
Study Details
Study Description
Brief Summary
TQB2223 is a recombinant, fully humanized antibody that binds lymphocyte activation gene-3 (LAG-3) and blocks the LAG-3/ major histocompatibility complex class II (MHC-II) interaction, thus allowing for increased T-cell proliferation and cytokine production. This is a phase I study to evaluate the safety, tolerability, pharmacokinetics (PK) and effectiveness of TQB2223 injection in combination with Penpulimab in subjects with advanced cancers.

Outcome Measures
Primary Outcome Measures
- Dose Limiting Toxicity (DLT) [During the first treatment cycle (21 days).]
DLT is defined as toxicities that meet pre-defined severity criteria of Common Terminology Criteria for Adverse Events (CTCAE) v5.0, and assessed as having a suspected relationship to TQB2223 injection, and unrelated to disease, disease progression, inter-current illness, or concomitant medications that occurs within the first cycle (21 days) of treatment.
- Maximum tolerated dose (MTD) [During the first treatment cycle (21 days).]
MTD was defined as the highest dose at which dose-limiting toxicity (DLT) occurred in less than 33% of patients.
- Objective Response Rate (ORR) [From date of the first dose until the date of first documented progression or date of death from any cause, assessed up to 100 weeks.]
Defined as the percentage of Complete Response (CR) plus partial response (PR) assessed by Response Evaluation Criteria In Solid Tumors (RECIST) v1.1 criteria and Guidelines for Response Criteria for Use in Trials Testing Immunotherapeutics (iRECIST) for solid tumors, Lugano 2014 criteria and Lymphoma Response to Immunomodulatory therapy Criteria (LYRIC) for lymphoma.
Secondary Outcome Measures
- Percentage of anti-drug antibody (ADA) positive patients [Pre-dose on Cycle 1, 2, 4, 8 . 30 days and 90 days after the last dose. Each cycle is 21 days.]
Percentage of ADA positive patients will be calculated to evaluate immunogenicity of TQB2223.
- The area under the curve (AUC) [5 minutes, 2 hour, 6 hours, 24 hours, 144 hours and 336 hours after dose on cycle 1 and cycle 3. Pre-dose on cycle 2, 4, 5, 6, 7, 8. Each cycle is 21 days.]
The area under the curve (AUC) of serum concentration of TQB2223
- Peak concentration (Cmax) [5 minutes, 2 hour, 6 hours, 24 hours, 144 hours and 336 hours after dose on cycle 1 and cycle 3. Pre-dose on cycle 2, 4, 5, 6, 7, 8. Each cycle is 21 days.]
Maximum observed concentration (Cmax) of TQB2223
- Terminal half-life (T1/2) [5 minutes, 2 hour, 6 hours, 24 hours, 144 hours and 336 hours after dose on cycle 1 and cycle 3. Pre-dose on cycle 2, 4, 5, 6, 7, 8. Each cycle is 21 days.]
The terminal elimination half-life (t 1/2) is the time that takes for the elimination processes to reduce the plasma concentration of the drug in the body by 50 %.
- Receptor occupation (RO) [5 minutes, 2 hour, 6 hours, 24 hours, 144 hours and 336 hours after dose on cycle 1 and cycle 3. Pre-dose on cycle 2, 4, 5, 6, 7, 8. Each cycle is 21 days.]
Receptor occupation (RO) of LAG-3 after administration.
- Objective Response Rate (ORR) [From date of the first dose until the date of first documented progression or date of death from any cause, assessed up to 100 weeks]
Defined as the percentage of Complete Response (CR) plus partial response (PR) assessed by Response Evaluation Criteria In Solid Tumors (RECIST) v1.1 criteria and Guidelines for Response Criteria for Use in Trials Testing Immunotherapeutics (iRECIST) for solid tumors, Lugano 2014 criteria and Lymphoma Response to Immunomodulatory therapy Criteria (LYRIC) for lymphoma.
- Disease control rate (DCR) [From date of the first dose until the date of first documented progression or date of death from any cause, assessed up to 100 weeks]
Defined as the proportion of subjects with CR, PR, or Stable Disease (SD).
- Duration of Response (DOR) [From date of the first dose until the date of first documented progression or date of death from any cause, assessed up to 100 weeks]
Defined as the time from first documented response to documented disease progression or death.
- Progression-free survival (PFS) [From date of the first dose until the date of first documented progression or date of death from any cause, assessed up to 100 weeks]
Defined as the time from the first dose of TQB2223 to the first occurrence of disease progression or death from any cause.
- Overall survival (OS) [From date of the first dose until the date of first documented progression or date of death from any cause, assessed up to 100 weeks]
Overall survival refers to the time from the first treatment to death from any cause.
- Number of patients with adverse events (AEs) [From the time of informed consent signed to 28 days after the last dose]
Assessed by the Common Terminology Criteria for Adverse Events (CTCAE) v5.0
- Number of patients with serious adverse events (SAEs) [From the time of informed consent signed to 28 days after the last dose]
Assessed by the Common Terminology Criteria for Adverse Events (CTCAE) v5.0
