Brief Summary
This phase I trial studies the side effects of human lysozyme goat milk in preventing graft versus host disease in patients with blood cancer undergoing a donor stem cell transplant. Sometimes the transplanted cells from a donor can cause an immune response against the body's own normal cells (call graft versus host disease). The goat milk in the study is from goats that have been genetically engineered to produce human lysozyme in the milk. Human lysozyme is a natural enzyme found in human milk and acts as an antimicrobial. Lysozyme is key to the digestive health of breast-fed human infants, since it helps the growth of beneficial gut bacteria and reduces the growth of bacteria that causes diarrhea and intestinal disease. Giving human lysozyme goat milk may reduce the rate of graft versus host disease in blood cancer patients undergoing a donor stem cell transplant.

Outcome Measures
Primary Outcomes (4)
Patients' ability to drink the specified daily amount of 750 ml human lysozyme goat milk (hLZ)
In the safety lead-in phase, we are going to investigate if a patient can drink the daily amount of 750 ml of hLZ.. The actual volume of milk consumed per day will be measured using graduated cups and recorded on daily basis. To calculate the average daily consumption, total volume of hLZ consumed by each patient for the whole inpatient stay will be divided by the total number of inpatient stay for that patient. Tolerable dose established based on the average daily hLZ consumption in the first 6 patients (safety lead-in) will be brought forward for additional study randomization.
from study initiation until up to 28 days post-transplant or until discharge, whoever comes first
Unacceptable toxicity
The modified Bearman Scale will be used to define unacceptable toxicity events. 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
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. Observed toxicities will be summarized in terms of type (organ affected or laboratory determination), severity, time of onset, duration, probable association with the study treatment and reversibility or outcome.
Up to 100 days post-transplant
Volume of hLZ consumed
Tolerability is defined as the ability to consume \>= 150 ml/day over the treatment period.
Up to 28 days post-transplant or date of discharge

Study Arms (2)
Group A (conditioning, goat milk, transplant, prophylaxis)
EXPERIMENTALCONDITIONING: Patients receive palifermin on days -10 to -8 and days 0 to 2, 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. HLZ: Patients receive human lysozyme goat milk PO TID on days -8 to 28 in the absence of disease progression or unacceptable toxicity. TRANSPLANT: Patients undergo stem cell transplant 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.
Group B (conditioning, transplant, prophylaxis)
ACTIVE COMPARATORCONDITIONING: 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 transplant 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.
