Efficacy and Safety of Tislelizumab Combined With Gemcitabine and Peraspartase in the Treatment of Patients With Primary Stage I-II NK/T Cell Lymphoma

February 27, 2026 updated by: Eye & ENT Hospital of Fudan University

A Study on the Efficacy and Safety of Tislelizumab in Combination With Gemcitabine and Sequential Pemetrexed Radiotherapy for Patients With Primary Stage I-II NK/T-Cell Lymphoma

In the past 10 years, there have been many effective explorations on the treatment of NK/TCL at home and abroad, which has innovated the treatment mode. Since ENKTCL-NT cells are sensitive to radiotherapy, radiotherapy is considered to be the most reliable treatment for ENKTCL-NT. Although patients with radiotherapy alone have excellent short-term efficacy and can achieve CR in 70-97% of patients, the 5-year PFS is only 30.5-61%, with a higher recurrence rate 5,6. The combination of chemotherapy and radiotherapy significantly improved the survival of patients compared with historical controls. Recent studies have shown that the advantage of radiotherapy combined with chemotherapy is that it can significantly reduce the later recurrence of patients with radiotherapy alone. However, the traditional synchronous chemotherapy and radiotherapy have many and serious adverse reactions and poor tolerance in patients, so it cannot be widely applied.

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

  • Adult
  • Older Adult

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
ORR
Time Frame: At 14 weeks after treatment initiation
Objective Response Rate; The proportion of patients who achieved pre-specified tumor volume reduction and maintained the minimum time frame required by accepted response evaluation criteria, such as Solid Tumor RECIST Version 1.1.
At 14 weeks after treatment initiation

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
PFS
Time Frame: up to 5 year
progression free survival; It refers to the time between the start of treatment and the onset of disease progression or death from any cause
up to 5 year

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
September 12, 2024

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
