TQB2928 Injection + Azacitidine for injection

Dose escalation:

Intravenous infusion of TQB2928 Injection once a week, combined with azacitidine for injection (75 mg/m2, d1-7/q4w), 4 weeks (28 days) as a treatment cycle.

Dose expansion:

The maximum tolerated dose (MTD) or optimal biological dose (OBD) or recommended phase II dose (RP2D) determined in the dose-escalation phase is combined with azacitidine for injection for extended studies to further observe the safety and efficacy.

Group Type EXPERIMENTAL

TQB2928 Injection + Azacitidine for injection

Intervention Type DRUG

TQB2928 injection is a fully humanized Immunoglobulin G 4 (IgG4) subtype monoclonal antibody targeting CD47.

Azacitidine for injection is a nucleoside metabolism inhibitor that inhibits DeoxyriboNucleic Acid (DNA) methyltransferase, reduces DNA methylation and alters gene expression.
