This study was a single-arm trial of autologous NK cell adjuvant therapy for relapsed/refractory non-Hodgkin's B-cell lymphoma. The locations isXiangyang No.1 People's Hospital, Hubei University of Medicine. The population was relapsed/refractory non-Hodgkin's B-cell lymphoma. The sample size was 33. The intervention was R-GemOx regimen combined with autologous NK cells. The dose of autologous NK cells was body surface area x (2-4) x 109 cells. The course of treatment was once every 14 days. The primary outcome measure was ORR. The duration of assessment was for each treatment cycle, 1 month, 3 months, 6 months, 9 months, 12 months, 18 months, 24 months, 3 years, and 5 years of treatment.

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
