Clinical Trial Summary

This randomized pilot phase I trial studies the side effects of human lysozyme goat milk in treating patients with blood cancer undergoing a donor stem cell transplant. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells (called graft-versus-host disease). Giving human lysozyme goat milk to patients undergoing a donor stem cell transplant may stop this from happening.

Description:

PRIMARY OBJECTIVES:

I. To evaluate the safety and feasibility of human lysozyme goat milk (hLZ) treatment by assessing type, frequency, severity, attribution, time course and duration of adverse events, including diarrhea, bloodstream/intestinal infections.

II. To evaluate the safety and feasibility of hLZ treatment by assessing patient compliance, the patients' ability to drink the specified volume (250 ml 3 x/day) of hLZ during the treatment period.

SECONDARY OBJECTIVES:

I. To compare the incidence and severity of adverse events (AE) among hLZ-treated and untreated patients, including diarrhea, bloodstream infections and intestinal infections.

II. To obtain preliminary estimates of gut microbiome diversity, as assessed by the Simpson Index, in hLZ-treated/untreated patients.

III. To compare gut microbiome diversity among hLZ-treated/untreated patients. IV. To obtain a preliminary estimate of the possible association between gut microbiome diversity and bloodstream infections.

V. To obtain a preliminary estimate of the possible association between gut microbiome diversity and acute graft versus host disease (GVHD) cumulative incidence, including time to onset.

VI. To characterize and compare GVHD inflammatory biomarkers (presence, level) among hLZ-treated and untreated patients.

VII. To characterize and compare urinary uindoxyl sulfate, tryptophan and kynurenine levels between hLZ-treated and untreated patients.

IX. To estimate overall survival (OS) cumulative incidence (CI) chronic GVHD of relapse/progression, and non-relapse mortality (NRM) at 100 days (excluding chronic GVHD), 6 months, 1 year and 2 years.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I:

CONDITIONING: Patients receive palifermin on days -10 to -8 and days 0 to 2, undergo fractionated total body irradiation (FTBI) on days -7 to -4, and receive cyclophosphamide on days -3 to -2 or etoposide on day -3 per City of Hope (COH) standard operating procedure (SOP) in the absence of disease progression or unacceptable toxicity.

HLZ: Patients receive human lysozyme goat milk orally (PO) three times daily (TID) on days -8 to 28 in the absence of disease progression or unacceptable toxicity.

TRANSPLANT: Patients undergo stem cell infusion on day 0.

GVHD PROPHYLAXIS: Beginning on day -2, patients receive tacrolimus and sirolimus daily per COH SOP in the absence of disease progression or unacceptable toxicity.

ARM II:

CONDITIONING: Patients receive palifermin on days -10 to -8 and days 0 to 2 per COH SOP, undergo FTBI on days -7 to -4, and receive cyclophosphamide on days -3 to -2 or etoposide on day -3 per COH SOP in the absence of disease progression or unacceptable toxicity.

TRANSPLANT: Patients undergo stem cell infusion on day 0.

GVHD PROPHYLAXIS: Beginning on day -2, patients receive tacrolimus and sirolimus daily per COH SOP in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for up to 2 years.

Unacceptable toxicity in a given patient is defined as either of the following that are considered at least possibly related to drinking hLZ milk: GI toxicity grade III or IV per Bearman scale or inability to consume hLZ milk for >7 days.	Up to 28 days post-transplant or date of discharge
Primary	Adverse events	Incidence and severity of adverse events will be reported according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version (v)4.03.
