A Prospective Study of PD-1 Inhibitor Combined With ICE in the Treatment of Relapsed/Refractory Gray Area Lymphoma
Study Details
Study Description
Brief Summary
There are no standard chemotherapy regimens for relapse/refractory gray area lymphoma. The programmed cell death ligand 1 (PD-L1) encoding gene is located in 9p24.1, so it is speculated that the programmed cell death pathway plays an important role in gray area lymphoma formation by evading immune surveillance in GZL.The purpose of this study was to evaluate the efficacy and safety of PD-1 monoclonal antibody combined with ICE in the treatment of patients with relapsed/refractory gray area lymphoma.

Phase 2 |
Detailed Description
The purpose of this study was to evaluate the efficacy and safety of PD-1 monoclonal antibody combined with ICE in the treatment of patients with relapsed/refractory gray zone lymphoma. The main study endpoint is the Objective Response Rate (ORR), including Complete Remission Rate (CRR) and Partial Remission Rate (PRR), was evaluated according to Lugano2014 lymphoma efficacy evaluation criteria.

Left ventricular ejection fraction (LVEF) ≥ 50% in cardiac function examination.
-
Serum pregnancy test was negative and effective contraceptive measures were taken from the signing of informed consent until 6 months after the use of the last chemotherapy.

Subjects must confirm the first forced expiratory volume (FEV1)/forced expiratory volume (FVC) >60% by pulmonary function test, unless large mediastinal mass compression fails to meet this standard;Carbon monoxide dispersion (DLCO), FEV1 and FVC all exceeded the predicted value by more than 50%.
-
Subjects who had received previous anti-tumor therapy were admitted only after the toxicity of previous therapy returned to CTCAE V5.0 level ≤1 or baseline;Class 2 toxicity (such as neurotoxicity, alopecia, and hearing loss) that was irreversible and not expected to worsen during the study period due to prior antitumor therapy were assessed by the investigator and were eligible for inclusion.
Exclusion Criteria:

Central nervous system involvement.
-
Participating in other clinical studies, or administering the first study drug less than 4 weeks after the end of treatment in the previous clinical study.
-
Had other malignant tumors in the past 5 years, except basal cell carcinoma of the skin, squamous cell carcinoma of the skin, carcinoma in situ of the breast, and carcinoma in situ of the cervix after radical treatment.
-
The last antitumor treatment was less than 3 weeks after the first administration of the drug in this study, including chemotherapy, immunotherapy, radiotherapy, and biotherapy (tumor vaccines, cytokines, or growth factors for cancer control).
-
Previous allogeneic hematopoietic stem cell transplantation or prior ASCT or CAR-T therapy within 1 month prior to initial dosing of the investigational drug.
-
Have previously received PD-1 or PD-L1 targeted therapy.
-
A history of severe hypersensitivity to monoclonal antibodies.
-
Major surgery was performed within 28 days prior to the start of study treatment.
-
In this study, the patients received anti-tumor Chinese herbal medicine or proprietary Chinese medicine within 7 days before the first medication.
