Correlation Between Gut Microbiota and Clinical Response to CAR-T Treatment for Hematological Malignancies

September 11, 2023 updated by: The First Affiliated Hospital of Soochow University

A Prospective and Observational Clinical Study of the Correlation Between Gut Microbiota and Clinical Response to CAR-T Treatment for Hematological Malignancies

The purpose of this prospective and observational study is to evaluate the correlation between gut microbiota and clinical response to CAR-T treatment for hematological malignancies

Detailed Description

Chimeric antigen receptor T-cell (CAR-T) therapy has shown impressive efficacy in hematological malignancies. However, response rates and associated immune-related adverse effects widely vary among patients. And no biomarkers have been identified to predict the efficacy and associated toxicities after CAR-T therapy in patients. Several preclinical experiments and clinical studies have shown that gut microbiota was associated with the efficacy of T cell-driven cancer immunotherapies and their toxicities. In hematologic malignancies, gut microbiota was associated with the development of graft-versus-host disease (GVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, the potential correlation between gut microbiota and the effificacy and toxicity of CAR-T therapy is unclear. Therefore, in this study, we aim to evaluate the correlation between gut microbiota and clinical response to CAR-T treatment for hematological malignancies.

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

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

  3. Expected survival time ≥ 3 months (according to investigator's judgement).
  4. Left ventricular ejection fractions ≥ 55% by echocardiography.
  5. ALT / AST <3 times of normal amounts.
  6. Creatinine<2.0mg/dl.
  7. PT and APPT <2 times of normal amounts.
  8. Karnofsky performance status ≥ 60.
  9. The ECOG score ≤2 points.

Exclusion Criteria:

  1. Pregnant (or lactating) women;
  2. Uncontrolled active infection；
  3. Active infection of hepatitis B virus or hepatitis C virus；
  4. Human immunodeficiency virus (HIV) positive；
  5. Patients with a history of myocardial infarction or severe arrhythmia within six months or those with class III or IV cardiac function according to the New York classification；

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

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 3, 2023

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.

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
