Brief Summary:
This randomized phase III trial studies how well Lactobacillus plantarum works in preventing acute graft versus host disease in children undergoing donor stem cell transplant. Lactobacillus plantarum may help prevent the development of gastrointestinal graft versus host disease in children, adolescents, and young adults undergoing donor stem cell transplant.

Condition or disease Intervention/treatment Phase
Malignant Neoplasm Procedure: Allogeneic Hematopoietic Stem Cell Transplantation Biological: Lactobacillus plantarum strain 299 Biological: Lactobacillus plantarum strain 299v Other: Placebo Administration Phase 3

Detailed Description:

PRIMARY OBJECTIVES:

I. To determine efficacy of orally-administered Lactobacillus plantarum (LBP) in preventing the development of gastrointestinal (GI) acute graft versus host disease (aGvHD) in children and adolescents undergoing alternative donor allogeneic hematopoietic cell transplantation (alloHCT).

EXPLORATORY OBJECTIVES:

I. To determine whether orally-administered LBP decreases the incidence of grade II-IV aGvHD following alternative donor alloHCT.

II. To determine whether LBP administration maintains intestinal integrity as measured by mean serum citrulline levels and reduction in mucosal barrier injury (MBI) bacteremia.

III. To measure the effects of LBP on the intestinal flora phylogenetic composition during and after alternative donor alloHCT using 16S ribosomal ribonucleic acid (rRNA) gene deep sequencing.

IV. To measure effects of LBP on intestinal flora function during and after alternative donor alloHCT using metagenomic and metabolite profiling.

V. To measure proposed immunomodulatory effects of LBP in mean serum levels of alloreactive-induced inflammatory cytokines (IL-2, IL-6, IL-12p70, IFN gamma, TNF alpha, etc) in patients receiving LBP compared to placebo.

VI. To determine whether LBP administration reduces the incidence of Clostridium difficile-associated diarrhea in alternative donor HCT patients.

VII. To determine whether LBP administration reduces hospital days within the first 120 days post hematopoietic cell transplant (HCT).

VIII. To define the safety of orally administered LBP strains 299 and 299v in alternative donor HCT patients as measured by incidence of Lactobacillus plantarum bacteremia.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive Lactobacillus plantarum strains 299 and 299v orally (PO) or through nasogastric (NG) or gastronomy (G) tube once daily (QD) on day 1 of transplant conditioning regimen to 56 days post alloHCT. Patients undergo alloHCT at day 0.

ARM II: Patients receive placebo PO or through NG or G tube QD on day 1 of transplant conditioning regimen to 56 days post alloHCT. Patients undergo alloHCT at day 0.

After completion of study treatment, patients are followed up for 120 days from alloHCT.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Incidence of stage 1-4 gastrointestinal (GI) acute graft versus host disease (aGVHD) [ Time Frame: Up to 120 days post stem cell infusion ]
    The proportion of eligible patients having stage 1-4 GI aGvHD incidence from Day 0 through Day 120 will be compared between the two arms.


Other Outcome Measures:
  1. Incidence of grade II-IV overall graft versus host disease [ Time Frame: Up to 120 days post stem cell infusion ]
    Similar analysis approach will be used as described for the primary outcome measure but using the dichotomous cumulative incidence of grade II-IV acute graft versus host disease as the endpoint measure.

  2. Incidence of blood stream infection [ Time Frame: Up to 120 days post stem cell infusion ]
    The incidence of mucosal barrier blood stream infections will be compared between two groups.

  3. Incidence of Clostridium difficile-associated diarrhea [ Time Frame: Up to 120 days post stem cell infusion ]
    Proportion of C. diff during the study period will be compared between arms.

  4. Plasma levels of citrulline [ Time Frame: Up to 120 days post stem cell infusion ]
    The citrulline levels at each of the time points will be summarized and described by arm.

  5. Graft versus host disease biomarkers [ Time Frame: Up to 120 days post stem cell infusion ]
    Descriptive analysis will be used to examine the association between graft versus host disease outcomes and bacterial genes, pathways, and metabolites.

  6. Blood/stool measures of intestinal flora assessed using sequencing [ Time Frame: Up to 120 days post stem cell infusion ]
    The association between Lactobacillus plantarum administration and bacterial genes and pathways, and bacterial metabolites will be evaluated.

  7. Laboratory correlative measures for allogeneic-induced inflammation [ Time Frame: Up to 120 days post stem cell infusion ]
    The effects of Lactobacillus plantarum on pro-inflammatory (LBP) cytokines in allogeneic hematopoietic cell transplantation recipients will be examined.

  8. Hospital days [ Time Frame: Up to 120 days post stem cell infusion ]
    Total hospital days over the study period is calculated as the duration between the date of admission for conditional therapy and the date of discharge (or the study end date). Hospital days will be compared between arms.

  9. Incidence of Lactobacillus plantarum bacteremia [ Time Frame: Up to 120 days post stem cell infusion ]
    Patients who have at least one incidence (positive) of Lactobacillus plantarum during any reporting period is considered evaluable for this aim. The proportion of C. diff during the study period will be compared between arms.
