Mecapegfilgrastim(PEG-G-CSF) for Prophylaxis of Chemotherapy-induced Neutropenia in Patients With Lymphoma

Efficacy and Safety of Mecapegfilgrastim(PEG-G-CSF) for Prophylaxis of Chemotherapy-induced Neutropenia in Patients With Lymphoma: a Randomized, Open-label, Active-controlled Trial

Neutropenia is one of the most frequent adverse effects of chemotherapy, and the main factor to limit the dosage and the continuation of chemotherapy.A newly pegylated rhG-CSF was independently developed by JIANGSU HENGRUI Medicine Co., Ltd, China. Phase 1a, 1b and phase 2 trials have shown that pegylated rhG-CSF has decreased renal clearance, increased plasma half-life, and prolonged efficacy in compare with filgrastim.

This study is to evaluate efficacy and safety in chemotherapy-induced neutropenia of once-per-cycle Mecapegfilgrastim Injection(PEG-G-CSF) and daily G-CSF in Patients with lymphoma patients.

Study Overview

• Status: Recruiting
• Conditions: Lymphoma; Chemotherapy-induced Neutropenia
• Intervention / Treatment: Drug: Pegylated rhG-CSF; Drug: rhG-CSF

Detailed Description

This is a randomized, controlled study. A total of 170 lymphoma patients who are eligible are planned to randomized assigned into two groups to receive mecapegfilgrastim fixed dose of 6 mg or filgrastim 5 µg/kg/day during chemotherapy.

The primary endpoint is the duration of grade ≥3 neutropenia in cycle 1. The secondary endpoints include incidence of grade ≥3 neutropenia and febrile neutropenia (FN) in cycle 1-4, The pharmacoeconomics and safety profile are also evaluated.
