Study of TQB2303 in Patients With Aggressive CD20 Positive Non-Hodgkin's Lymphoma

Phase 1

• Conditions: Non-hodgkin's Lymphoma
• Interventions: Drug: TQB2303; Drug: Rituximab

• Registration Number: NCT03456466
• Lead Sponsor: Chia Tai Tianqing Pharmaceutical Group Co., Ltd.

Brief Summary

Primary Outcome Measures:

Area under the curve (AUC) forTQB2303 and rituximab concentrations \[ Time Frame: 85 days \]

Secondary Outcome Measures:

The Maximum Concentration (Cmax) of the TQB2303 and rituximab \[ Time Frame: 85 days \] The area under the plasma concentration-time curve from 0 to inf (infinite) time (AUC0-∞); The time to reach the maximum plasma concentration after treatment (Tmax) Total clearance (CL); Elimination of half-life (t1 / 2); Apparent distribution volume (Vd).
