Clinical Trial of TQB2928 in Combination With a Third-Generation Epidermal Growth Factor Receptor (EGFR) Tyrosine Kinase Inhibitor (TKI) in Patients With Advanced Non-Small Cell Lung Cancers

Official title

A Phase Ib Clinical Study of TQB2928 in Combination With a Third-Generation EGFR TKI in Patients With Advanced Non-Small Cell Lung Cancers

Overview

This is a Phase Ib study to evaluate the safety, tolerability, and efficacy of TQB2928 in combination with third-generation EGFR TKIs in subjects with advanced non-small cell lung cancer, and to determine the recommended Phase II dose (RP2CD).

Interventions

• Drug TQB2928 injection + Almonertinib Mesilate Tablets
  TQB2928 is a recombinant fully humanized Immunoglobulin G4 (IgG4) monoclonal antibody that can promote tumor cell phagocytosis by macrophages and exert anti-tumor effects. Almonertinib Mesilate Tablets is a third generation of EGFR-TKI targeting drug.

Primary outcome measures

• Phase II recommended combination doses (RP2CD) [Time frame: Baseline up to 24 months]
• Objective Response Rate (ORR) [Time frame: Up to 2 years]
• Duration of Response (DOR) [Time frame: Up to 2 years]
• Progression-free survival (PFS) [Time frame: Up to 2 years]
• Time to Progression [Time frame: Up to 2 years]

Secondary outcome measures (7)

• Elimination half-life (t1/2) [Time frame: Cycle 1 Day1: in 0.5 hour pre-dose and immediately after dose, 2, 6, 24 hours; Day1 and Day15 of Cycle 1, Cycle 2 Day1: in 0.5 hour pre-dose and immediately after dose; Day1 on Cycle 3, Cycle 4, Cycle 5: in 0.5 hour pre-dose (each cycle is 3 weeks)]
• Area under the plasma concentration-time curve (AUC0-last) [Time frame: Cycle 1 Day1: in 0.5 hour pre-dose and immediately after dose, 2, 6, 24 hours; Day1 and Day15 of Cycle 1, Cycle 2 Day1: in 0.5 hour pre-dose and immediately after dose; Day1 on Cycle 3, Cycle 4, Cycle 5: in 0.5 hour pre-dose (each cycle is 3 weeks)]
• Apparent Plasma Clearance (CL) [Time frame: Cycle 1 Day1: in 0.5 hour pre-dose and immediately after dose, 2, 6, 24 hours; Day1 and Day15 of Cycle 1, Cycle 2 Day1: in 0.5 hour pre-dose and immediately after dose; Day1 on Cycle 3, Cycle 4, Cycle 5: in 0.5 hour pre-dose (each cycle is 3 weeks)]
• Apparent volume of distribution(Vz) [Time frame: Cycle 1 Day1: in 0.5 hour pre-dose and immediately after dose, 2, 6, 24 hours; Day1 and Day15 of Cycle 1, Cycle 2 Day1: in 0.5 hour pre-dose and immediately after dose; Day1 on Cycle 3, Cycle 4, Cycle 5: in 0.5 hour pre-dose (each cycle is 3 weeks)]
• Steady-state trough concentration (Css-min) [Time frame: Cycle 1 Day1: in 0.5 hour pre-dose and immediately after dose, 2, 6, 24 hours; Day1 and Day15 of Cycle 1, Cycle 2 Day1: in 0.5 hour pre-dose and immediately after dose; Day1 on Cycle 3, Cycle 4, Cycle 5: in 0.5 hour pre-dose (each cycle is 3 weeks)]
• Immunogenicity: anti-drug antibody (ADA) [Time frame: From the time of informed consent signed through 90 days after the last dose]
• Adverse Events (AE) rate [Time frame: From date of the first dose until the date of 30 days after last dose or new anti-tumor treatment, whichever came first]
