Clinical Trial of the TQB2928 Injection in Patients With Advanced Cancers

Phase 1

Recruiting

• Conditions: Advanced Cancer
• Interventions: Drug: TQB2928 injection

• Registration Number: NCT05192512
• Lead Sponsor: Chia Tai Tianqing Pharmaceutical Group Nanjing Shunxin Pharmaceutical Co., Ltd.

Brief Summary

TQB2928 is a promising new molecular entity that mediates blockade of CD47 and SIRPα (Signal Regulatory Protein Alpha) and enhances the phagocytosis of cancer cells by macrophages. This is a study to evaluate the safety, tolerability and effectiveness of TQB2928 injection in subjects with advanced malignancies.

Arm && Interventions

Group	Intervention	Description
TQB2928 injection	TQB2928 injection	weekly intravenous (IV) infusions for four times (Days 1, 8, 15, and 22) of TQB2928 in each 28-day treatment cycle

Primary Outcome Measures

Name	Time	Method
Maximum tolerated dose (MTD)	During the first 28 days	MTD is defined as the highest dosing schedule cohort level at which no more than 1 of 6 patients experience a Dose Limiting Toxicity (DLT).
Dose Limiting Toxicity (DLT)	During the first 28 days	DLT will be assessed during the first 28 days of treatment for dose-escalation and are defined as toxicities that meet pre-defined severity criteria, and assessed as having a suspected relationship to study drug, and unrelated to disease, disease progression, inter-current illness, or concomitant medications that occurs within the first cycle (28 days) of treatment.

Secondary Outcome Measures

Name	Time	Method
Pharmacokinetics: T1/2	Cycle 1 Day 1 and Cycle 1 Day 22: pre-dose, and 0.08, 2, 6, 24 and 72 hours after infusion. Cycle 1 Day 8, Cycle 1 Day 15, Cycle 2 Day 1, Cycle 2 Day 15, Cycle 3 Day 1: pre-dose and end of the infusion. Each cycle is 28days.	Terminal half-life (T1/2)
Disease control rate (DCR)	up to 2 years	Defined as the proportion of subjects with CR, PR, or SD (Stable Disease).
Progression-free survival (PFS)	up to 2 years	Defined as the time from the first dose of TQB2928 to the first occurrence of disease progression or death from any cause.
Pharmacokinetics: AUC	Cycle 1 Day 1 and Cycle 1 Day 22: pre-dose, and 0.08, 2, 6, 24 and 72 hours after infusion. Cycle 1 Day 8, Cycle 1 Day 15, Cycle 2 Day 1, Cycle 2 Day 15, Cycle 3 Day 1: pre-dose and end of the infusion. Each cycle is 28days.	The area under the curve (AUC) of serum concentration of TQB2928
Pharmacokinetics: Cmin	Cycle 1 Day 1 and Cycle 1 Day 22: pre-dose, and 0.08, 2, 6, 24 and 72 hours after infusion. Cycle 1 Day 8, Cycle 1 Day 15, Cycle 2 Day 1, Cycle 2 Day 15, Cycle 3 Day 1: pre-dose and end of the infusion. Each cycle is 28days.	Minimum observed concentration (Cmin) of TQB2928 at steady state
Objective Response Rate (ORR)	up to 2 years	Defined as the percentage of Complete Response (CR) plus partial response (PR) assessed by Response Evaluation Criteria In Solid Tumors (RECIST) v1.1 criteria for solid tumors, Lugano 2014 criteria and lymphoma response to immunomodulatory therapy criteria (LYRIC) for lymphoma, and acute myeloid leukemia (AML) IWG 2003 response criteria for AML.
Number of patients with adverse events (AEs) and serious adverse events (SAEs)	From the time of informed consent signed to 90 days after the last dose	Assessed by the Common Terminology Criteria for Adverse Events (CTCAE) v5.0
Percentage of anti-drug antibody (ADA) positive patients	From the time of informed consent signed through 90 days after the last dose.	Percentage of ADA positive patients will be calculated to evaluate immunogenicity of TQB2928.
