GVM±R in Patients With Relapsed or Refractory Aggressive NHL

This is a single-arm, single-center, dose-escalation clinical study to explore the maximum tolerated dose (MTD) of liposomal mitoxantrone hydrochloride when combined with gemcitabine, vinorelbine and/or rituximab (GVM ± R) in patients with relapsed or refractory aggressive non-Hodgkin lymphoma (NHL). Liposomal mitoxantrone hydrochloride will be given on day 1 at four different doses (16 mg/m2, 18 mg/m2, 20 mg/m2,22 mg/m2) and be combined with gemcitabine, vinorelbine and/or rituximab (rituximab only in CD20+ lymphoma). The dose limited toxicity (DLT) will be evaluated after the first cycle of therapy. A maximum of 6 cycles of therapy are planned.
