Fecal Microbiome Transplant to Remodel Intestinal Microbiota for Patients With Relapsed or Refractory Lymphoma With Exposure to High-Risk Antibiotics Who Are Receiving Chimeric Antigen Receptor T Cells

Summary

This phase II trial tests how well fecal microbiome transplantation works to remodel intestinal microbiota for patients with lymphoma that has come back after a period of improvement (relapsed) or that does not respond to treatment (refractory) with exposure to high-risk antibiotics who are receiving chimeric antigen receptor (CAR) T cells. Fecal microbiome transplantation consists of fecal microbiota from healthy donors with healthy gut microbiota that allows re-population of the patient's microbiome with diverse protective microorganisms. CAR T-cell therapy is a type of treatment in which a patient's T cells (a type of immune system cell) are changed in the laboratory so they will attack cancer cells. T cells are taken from a patient's blood. Then the gene for a special receptor that binds to a certain protein on the patient's cancer cells is added to the T cells in the laboratory. The special receptor is called a chimeric antigen receptor (CAR). Large numbers of the CAR T cells are grown in the laboratory and given to the patient by infusion for treatment of certain cancers. Part of the treatment for CAR T therapy involves high doses of chemotherapy. This, along with prior exposure to high strength antibiotics, can damage patient's intestinal microbiota. Giving fecal microbiome transplantation may improve clinical response by repairing intestinal microbiota for patients with relapsed or refractory lymphoma who had exposure to high-risk antibiotics.

* Seronegative for HIV antigen (Ag)/antibody (Ab) combo, hepatitis C virus (HCV), active hepatitis B virus (HBV) (surface antigen negative)

  * HIV-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial.
* Meets other institutional and federal requirements for infectious disease titer requirements

  * Note: Infectious disease testing to be performed within 28 days prior to day 1 of protocol therapy
* Women of childbearing potential (WOCBP): negative urine or serum pregnancy test

  * If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
* Agreement by females and males of childbearing potential\* to use an effective method of birth control or abstain from heterosexual activity for the course of the study through at least 12 months after the last dose of protocol therapy.

  * Childbearing potential defined as not being surgically sterilized (men and women) or have not been free from menses for \> 1 year (women only)

Exclusion Criteria:

* Major surgery in 4 months preceding enrollment
* No live vaccine in 30 days prior to enrollment
* Inability to swallow capsules or history of disorder with Inability to swallow FMT capsules
* History of inflammatory bowel disorder, irritable bowel disorder
* Severe food allergies
* History of chronic aspiration
* History of behavioral disorders including substance abuse disorders which per discretion of primary investigator will interfere with safe conduct and compliance to study treatment
* History neurocognitive disorder which per discretion of primary investigator will interfere with safe conduct and compliance to study treatment
* Diagnosis of primary immunodeficiency
* Active second malignancy requiring treatment except non-melanoma skin cancer or carcinoma in situ-cervix, bladder or to non-metastatic prostate cancer which does not require treatment
* Uncontrolled bacterial, fungal, or viral infection confirmed using clinical, laboratory and radiological findings requiring administration of intravenously (IV) antimicrobials
* Any clinical, laboratory or radiologic findings per discretion of primary investigator will interfere with safe conduct of study treatment and compliance with study procedures
* Any other condition that would, in the Investigator's judgment, contraindicate the patient's participation in the clinical study due to safety concerns with clinical study procedures
* Prospective participants who, in the opinion of the investigator, may not be able to comply with all study procedures (including compliance issues related to feasibility/logistics)
