Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Peripheral T-cell lymphomas (PTCLs) are malignancies of immunologically mature T-cells that arise in peripheral lymphoid tissues. Compared with B-cell lymphoma, the treatment methods of PTCL are more limited, the first-line therapy is usually CHOP-like therapy, but the efficacy is poor, 5-year overall survival rate (OS) is only 30%-40%. Anti-PD-1 monoclonal antibody, Lenalidomide and Azacitidine can all have tumor-killing effects, and the three have complementary theoretical basis in the mechanism of action. This study will evaluate the efficacy and safety of Anti-PD-1 monoclonal antibody Combined Lenalidomide and Azacitidine in Relapsed/Refractory Peripheral T-cell Lymphoma patients.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  5. Subjects of child-bearing or child-fathering potential must be willing to practice birth control from the time of enrollment on this study until the follow-up one year period of the study.
  6. Estimated survival time ≥3 months.
  7. Voluntary signing of informed consent.

Exclusion Criteria:

  1. Accepted major surgery within 4 weeks before treatment.
  2. Prior malignancy (other than Relapsed/Refractory Peripheral T-cell Lymphoma), except for cured malignant tumors with no active lesions for 3 years;Adequate treatment of inactive lesions in non-melanoma skin cancer,malignant tonsilloma or carcinoma in situ;
  3. Patients who have previously received failed allogeneic hematopoietic stem cell transplantation.
  4. Have stroke or intracranial hemorrhage within 3 months.
  5. Evidence of complications or medical conditions, including but not limited, that may interfere the conduct of the study or place the patient at serious risk:significant cardiovascular disease(class 3 or 4 cardiac disease as defined by the New York Heart Association Functional Classification、myocardial infarction within 6 months of screening、uncontrolled or symptomatic arrhythmias) and/or significant lung disease.
  6. HIV infection and/or active hepatitis B or active hepatitis C.
  7. Uncontrolled systemic infection.
  8. Pregnant or breasting-feeding women.
  9. According to the researchers' judgment, any life-threatening disease, medical condition or organ system dysfunction which can endanger the patient's safety and Interfer with the absorption or metabolism of anti-PD-1 monoclonal antibody plus Lenalidomide and Azacitidine,may put the results of a study at unnecessary risk.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Overall Response Rate (ORR) at 6 cycles
Time Frame: From date of first dose until completion of 6 treatment cycles, assessed up to approximately 20 weeks.
The percentage of participants achieving a best overall response of confirmed Complete Response (CR) or Partial Response (PR) after treatment by Anti-PD-1 antibody plus Lenalidomide and Azacitidine.
From date of first dose until completion of 6 treatment cycles, assessed up to approximately 20 weeks.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Adverse events profile
Time Frame: Measured from start of treatment until 28 days after last dose
Number of participants with adverse events. Frequencies of toxicities based on the NCI Common Terminology Criteria for Adverse Events (CTCAE), version 5.0 will be tabulated
Measured from start of treatment until 28 days after last dose
Complete Response Rate at 6 cycles
Time Frame: From date of first dose until completion of 6 treatment cycles, assessed up to approximately 20 weeks.
The percentage of patients who achieved complete response after treatment by Anti-PD-1 antibody plus Lenalidomide and Azacitidine
From date of first dose until completion of 6 treatment cycles, assessed up to approximately 20 weeks.
3-year progression-free survival (PFS) rate
Time Frame: up to 3 years
3-year PFS rate is defined as the percentage of participants who are alive and free from disease progression at 3 years from the first dose of treatment. Participants who are alive and progression-free or lost to follow-up before 3 years will be censored at the date of last adequate tumor assessment.
