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

This Phase II, open-label, single-center, non-randomized study will evaluate the safety and efficacy of induction treatment consisting of Sintilimab in combination with Rituximab plus chemotherapy (R-CHOP) as the first-line treatment in participants with DLBCL, followed by consolidation treatment with Sintilimab alone in patients who achieve CR at the end of induction.For safety reasons, the initial enrollment of the first 6 patients in the study will be slow and conduct intensive monitoring for safety. If the dose-limited toxicity event was observed in more than 2 of the first 6 patients and was assessed caused by cumulative exposure to the study drug combination therapy, the trial will be stopped.This study also aim to evaluate the correlation of clinical efficacy to the expression of PD-L1,PD-1,CD3,CD4,CD8,CD56,CD58,β2-MG，HLA-DR/DP/DQ and so on by immunohistochemical techniques.

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.

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
complete remission rate
Time Frame: every 3 months until 30 months after the last patient's enrollment.
complete remission rate after treated by Sintilimab+ R-CHOP regimen.
every 3 months until 30 months after the last patient's enrollment.

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
overall survival
Time Frame: 30 months after the last patient's enrollment
from the date of inclusion to date of death, irrespective of cause
30 months after the last patient's enrollment
adverse events
Time Frame: from the date of first cycle of treatment to 30 months after last patient's enrollment
any unfavorable and unintended sign , symptom, or disease temporally associated with the use of a medical treatment or procedure that may or may not be considered related to the medical treatment or procedure.For safety reasons, the initial enrollment of the first 6 patients in the study will be slow and conduct intensive monitoring for safety. the monitoring time window for each patient is 21 days after the first treatment. If the dose-limited toxicity event was observed in more than 2 of the first 6 patients and was assessed by the research team as caused by cumulative exposure to the study drug combination therapy, the trial will be stopped.
