NCT ID: NCT04052659

Last Updated: 2021-03-09

Basic Information

• Recruitment Status: NOT_YET_RECRUITING
• Clinical Phase: PHASE2
• Total Enrollment: 30 participants
• Study Classification: INTERVENTIONAL

Brief Summary

This is a single-arm, single-center Phase II clinical trial for patients with relapsed or refractory Peripheral T-cell lymphoma (PTCL). Immunotherapy with anti-PD-1 antibodies, such as sintilimab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chidamide and azacitidine may respectively stop the growth of tumor cells by blocking histone deacetylation and DNA methylation enzymes needed for cell growth. Giving chidamide and azacitidine with sintilimab these three drugs may work better than single drug or combination of two drugs in treating patients with relapsed or refractory peripheral T-cell lymphoma.

Detailed Description

PRIMARY OBJECTIVES:

To determine the objective response rate (ORR).

SECONDARY OBJECTIVES:

1. To determine the complete response rate (CRR).

2. To determine the duration of response (DOR).

3. To determine the progression free survival (PFS).

4. To determine the overall survival (OS).

5. To determine the safety.

EXPLORATORY OBJECTIVES:

Assess the correlation between the expression of PD-L1, CD4, CD8, CD68 in tumor microenvironment and the efficacy of combined therapy in relapsed or refractory peripheral T-cell lymphoma.

Exclusion Criteria

• Known central nervous system lymphoma or cutaneous T-cell lymphoma;
• Received any immunesuppressive drugs within 4 weeks of the first dose of study medicationy, not including topical corticosteroids or systemic corticosteroids in physiological doses (≤10 mg/day prednisone or equivalent dose of other steroid);
• Patients with active autoimmune diseases requiring systematic treatment in the past two years;
• Received or plan to receive any attenuated vaccines within 4 weeks of the first dose of study medication;
• Received the last anti-tumor therapy within 4 weeks of the first dose of study medication or have not recovered (recovery defined as baseline or ≤ grade 1) from adverse events due to anti-cancer agents;
• Currently participating in an interventional clinical study, unless participating in observational study or during follow-up period of an interventional study;
• Received any investigational agent within 4 weeks of the first dose of study medication;
• Subjects with interstitial lung disease or lung disease that may interfere with the detection or treatment of suspected drug-related pulmonary toxicity;
• Other primary malignancy;
• Known history of allogeneic organ or allogeneic hemopoietic stem cell transplantation;
