Efficacy and Safety of Chidamide Combined With PD-1 Inhibitor as Maintenance Therapy Following CAR-T Cell Treatment With TP53-Mutated Large B-Cell Lymphoma (LBCL) (CP-LBCL)

12. november 2026 opdateret af: Aibin Liang,MD,Ph.D., Shanghai Tongji Hospital, Tongji University School of Medicine

A Prospective, Single-Arm, Single-Center Study on the Efficacy and Safety of Chidamide Combined With PD-1 Inhibitor as Maintenance Therapy Following CAR-T Cell Treatment in Patients With TP53-Mutated Large B-Cell Lymphoma (LBCL)

This is a study for patients with a type of blood cancer called large B-cell lymphoma (LBCL) who have a mutation in a gene called TP53. This gene mutation often makes the cancer harder to treat with standard therapies.

CAR T-cell therapy is a treatment that uses a patient's own immune cells to fight cancer. However, some patients relapse (the cancer comes back) after CAR T-cell therapy. This study will test whether taking two drugs - chidamide (a tablet taken by mouth) and a PD-1 inhibitor (given by intravenous infusion) - as maintenance therapy after CAR T-cell therapy can help keep the cancer from coming back.

Participants in this study will receive CAR T-cell therapy, followed by maintenance treatment with chidamide combined with a PD-1 inhibitor. Doctors will closely monitor participants for how well the treatment works and for any side effects. The study will take place at a single hospital, and all participants will receive the same treatment.

The main goal of the study is to find out if this maintenance treatment is effective and safe for patients with TP53-mutant large B-cell lymphoma.

Intervention / Behandling
Eksperimentel: Chidamide + PD-1 Inhibitor Maintenance

Participants will receive CAR T-cell therapy as planned by the treating physician. After CAR T-cell infusion, participants will receive maintenance therapy with oral chidamide combined with an intravenous PD-1 inhibitor, continued until disease progression, unacceptable toxicity, withdrawal of consent, or completion of the planned maintenance duration. Treatment response and adverse events will be monitored regularly.

Chidamide is an oral subtype-selective histone deacetylase (HDAC) inhibitor. Participants will take chidamide orally at the dose of 20mg twice week and schedule specified in the protocol, starting after CAR T-cell infusion, and continuing until disease progression, unacceptable toxicity, or completion of the planned maintenance duration.

Sintilimab is a humanized anti-programmed death-1 (PD-1) monoclonal antibody administered by intravenous infusion. Participants will receive it at the dose of 200mg/21days, in combination with oral chidamide, until disease progression, unacceptable toxicity, or completion of the planned maintenance duration.
