SHR2554 Plus Liposomal Mitoxantrone as First-line Treatment for Peripheral T-cell Lymphoma (PTCL)

Официальное название

An Open-label, Multicenter, Phase Ib/II Exploratory Clinical Study of EZH2 Inhibitor SHR2554 in Combination With Liposomal Mitoxantrone for the First-line Treatment of Peripheral T-cell Lymphoma

Обзор

This is a single-arm, multicenter, Phase Ib/IIa study designed to explore the efficacy and safety of SHR2554 in combination with liposomal mitoxantrone for the treatment of patients with treatment-naive peripheral T-cell lymphoma (PTCL). The study is divided into a Phase Ib safety lead-in phase and a Phase IIa dose expansion phase.

Вмешательства

• Препарат SHR2554 combined with Liposomal Mitoxantrone
  Patients will receive 6 cycles of SHR2554 combined with liposomal mitoxantrone as induction therapy. All patients who achieve a complete response (CR) after induction therapy are eligible for transplantation. Patients achieving CR or partial response (PR), as well as those post-transplantation, may receive SHR2554 maintenance therapy in 28-day cycles. Maintenance therapy will continue until disease progression or other reasons for discontinuation. The maximum duration of SHR2554 administration i
