Clinical Study of Liposomal Mitoxantrone Hydrochloride Injection Combined With Pegaspargase in the Treatment of NKTCL

Phase 1

Terminated

• Conditions: Extranodal NK/T-cell Lymphoma, Nasal Type

• Registration Number: NCT04509466
• Lead Sponsor: CSPC ZhongQi Pharmaceutical Technology Co., Ltd.

Brief Summary

This is a multicentre, open-label, single-arm, phase I/II clinical study to evaluate the safety, efficacy and pharmacokinetics of liposomal mitoxantrone hydrochloride in combination with pegaspargase in patients with extranodal natural killer/T-cell lymphoma, nasal type (NKTCL).

Detailed Description

This is a multicentre, open-label, single-arm, phase I/II clinical study with a dose-escalation stage (part 1) and a dose-expansion stage (part 2). In part 1, patients with treatment-naïve, relapsed/refractory extranodal natural killer/T-cell lymphoma (nasal type) will be assigned to receive sequentially higher doses of liposomal mitoxantrone hydrochloride plus a standard dose of pegaspargase every 21 days (a cycle). The dose escalation initially will follow an accelerated titration design for the first two dosing groups, then follow a classic 3+3 design. All dose-escalation decisions will be based on the safety data generated from the currently highest dose group. The maximum tolerated dose (MTD) and the recommended Phase 2 dose (RP2D) of liposomal mitoxantrone hydrochloride will be determined in part 1. In part 2, additional patients will be recruited into two groups,the treatment-naïve group and the relapsed or refractory group, to receive liposomal mitoxantrone hydrochloride at the RP2D combined with a standard dose of pegaspargase. All patients will receive the treatment until disease progression, or observation of unacceptable grade 3 drug-related adverse events (a maximum of 6 cycles).
