Relmacabtagene Autoleucel Combined With Autologous Hematopoietic Stem Cell Transplantation, Orelabrutinib, and Sintilimab for Primary Central Nervous System Lymphoma

Официальное название

A Prospective, Multicenter Clinical Study of Relmacabtagene Autoleucel Combined With Autologous Hematopoietic Stem Cell Transplantation, Orelabrutinib, and Sintilimab for Primary Central Nervous System Lymphoma

Обзор

To evaluate the efficacy and safety of relmacabtagene autoleucel combined with autologous hematopoietic stem cell transplantation, orelabrutinib, and sintilimab as first-line or relapsed/refractory treatment for primary central nervous system diffuse large B-cell lymphoma.

Вмешательства

• Препарат Relmacabtagene autoleucel and transplantation
  This study enrolled patients with primary central nervous system lymphoma, from whom mononuclear cells and hematopoietic stem cells were collected. Participants receive infusions of hematopoietic stem cells and CAR-T cells, followed by maintenance therapy with orelabrutinib and sintilimab starting on day 15 post-transplantation, for a median duration of up to 6 months and 1 year, respectively.
