Zanubrutinib Plus Lenalidomide for Frail Elderly Patients With Newly Diagnosed PCNSL

This is a prospective, single-arm, phase II clinical study evaluating the efficacy and safety of Zanubrutinib (a BTK inhibitor) plus Lenalidomide (an immunomodulatory drug) in frail elderly patients with newly diagnosed primary central nervous system lymphoma (PCNSL). The study plans to enroll 33 patients who are aged ≥ 70 years and classified as frail, a population for whom standard first-line treatment regimens, high-dose methotrexate-based chemotherapy, may be "unfit". This study includes screening phase, induction phase, consolidation phase and maintenance phase. The screening period is defined as within 1 week prior to the first dose. During induction, participants will receive Zanubrutinib 160 mg orally twice daily continuously and Lenalidomide 25 mg orally once daily on days 1-21 of each 28-day cycle for three cycles. Participants who achieve a partial response (PR) or complete response (CR) after induction will receive three additional 28-day consolidation cycles of the same regimen. Participants who achieve a CR after consolidation will continue maintenance treatment with Zanubrutinib and Lenalidomide until disease progression. Treatment response will be assessed throughout the study using the International Primary CNS Lymphoma Collaborative Group (IPCG) criteria and assessed every 3 months. The primary endpoint is the complete response rate (CRR) at the end of induction therapy. Secondary endpoints include overall response rate (ORR) at the end of induction therapy, CRR and ORR at the end of consolidation therapy, One-year and two-year progression-free survival (PFS) rates, Duration of response (DOR), overall survival (OS), adverse event (AE) and serious adverse event (SAE). Exploratory liquid-biopsy analyses will be performed to evaluate treatment response and prognosis.

Application of PD-1 Inhibitors, Tenofovir, Chidamide, and Lenalidomide in Relapsed/Refractory EBV-associated Lymphoproliferative Disorders.

This study is a prospective, multicenter, single-arm clinical trial designed to evaluate the efficacy and safety of PD-1 inhibitor combined with tenofovir, chidamide, and lenalidomide in the treatment of relapsed or refractory Epstein-Barr virus (EBV)-associated lymphoproliferative disorders (LPDs). The primary endpoint is the overall response rate (ORR) at 3 months, including complete response (CR) and partial response (PR). Secondary endpoints include overall survival (OS), progression-free survival (PFS), as well as safety and tolerability assessments. Eligible patients must have histologically confirmed EBV-positive B-cell or T/NK-cell LPDs with measurable lesions. This combination regimen targets multiple mechanisms, including inhibition of EBV replication, activation of the immune system, and enhancement of antitumor effects, aiming to provide an innovative therapeutic strategy for this challenging disease.

Application of PD-1 Inhibitors Combined With Tenofovir, Chidamide and Lenalidomide in the Treatment of EBV-associated Diseases.

Currently, treatment options for Epstein-Barr virus (EBV) infection are limited, with unsatisfactory efficacy and no established standard therapy. Therefore, our center is conducting a prospective, multicenter, single-arm clinical trial to evaluate the efficacy and safety of PD-1 inhibitor in combination with tenofovir, chidamide, and lenalidomide in patients with EBV infectious diseases, aiming to provide a more effective and safer therapeutic option for EBV infectious diseases.

Efficacy and Safety of Lenalidomide Plus CHOP vs CHOP in Patients With Untreated Peripheral T-Cell Lymphoma

This study aims to compare the efficacy and safety of lenalidomide plus CHOP (L-CHOP) versus CHOP alone in patients with previously untreated peripheral T-cell lymphoma (PTCL)
