A Multicenter, Prospective, Randomized, Controlled Study of Decitabine in Combination With R-CHOP for Initial Treatment of EBV+ Diffuse Large B-cell Lymphoma

January 9, 2026 updated by: Second Affiliated Hospital of Nanchang University

This trial was a prospective, multicenter, randomized, controlled Phase III clinical design to compare the efficacy and safety of decitabine combined with R-CHOP (R-CHOP-D) versus R-CHOP in the treatment of primary EBV+ diffuse large B-cell lymphoma (DLBCL).

Sixty patients were randomized 1:1 into R-CHOP-D (trial group) or R-CHOP (control group). The trial consisted of a screening period (days -28 to -1), a treatment period, and a follow-up period (2 years after the end of the last trial).

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Initial treatment of diffuse large B-cell lymphoma (DLBCL) confirmed by tumor histopathology with at least one lesion on either axis More than 1.5 cm, sufficient specimens for second-generation sequencing or single-cell sequencing;
  2. Age > 18 years old, < 80 years old, gender unlimited;
  3. EBER+ or peripheral blood EBV-DNA of pathological specimen was greater than 103copy/ml;
  4. Patients judged by the investigator to have a life expectancy of at least 6 months;
  5. The patient or his legal representative must provide written informed consent prior to any research special examination or procedure.
  6. Signed written informed consent before screening.

Exclusion Criteria:

  1. Have previously received systemic or local treatment including chemotherapy;
  2. Previously received autologous stem cell transplantation;
  3. Previous history of other malignant tumors, except skin basal cell carcinoma and cervical carcinoma in situ;
  4. Accompanied by uncontrolled cardiovascular and cerebrovascular diseases, coagulation disorders, connective tissue diseases and serious infectious diseases;
  5. Lymphoma involves the central nervous system;
  6. Primary mediastinal large B-cell lymphoma;
  7. Left ventricular ejection fraction < 50%;

  8. Laboratory test values at the time of screening: (unless due to lymphoma);

    1. Neutrophils < 1.5 x 109/L;
    2. Platelet < 75 x 109/L;
    3. ALT or AST were 2 times higher than the upper limit of normal, AKP and bilirubin were 1.5 times higher than the upper limit of normal;
    4. creatinine levels higher than 1.5 times the upper limit of normal;
  9. Patients with mental illness or other patients known or suspected to be unable to fully comply with the study protocol;
  10. Pregnant or lactating women;
  11. Known human immunodeficiency virus (HIV) infection, or active hepatitis B or C virus infection (polymerase chain Reaction [PCR] showed positive results). If the HbsAg test result is positive, HBV DNA test should be performed, if the HBV DNA<103IU/ml, can be enrolled. If HBsAg test results are negative, but HBcAb test is positive (regardless of HBsAb status), HBV DNA test is also required, and HBV DNA<103 IU/ml can be enrolled. If the patient's HCV antibody is positive, the HCV RNA is detected by PCR. If positive, the exclusion criteria are met.
  12. Other concurrent and uncontrolled medical conditions that the investigator believes will affect the patient's participation in the study.
