Human Lysozyme Goat Milk for the Prevention of Graft Versus Host Disease in Patients With Blood Cancer Undergoing a Donor Stem Cell Transplant

Running, not enrolling · Phase 1

Conditions studied: Allogeneic Hematopoietic Stem Cell Transplant Recipient, Hematopoietic and Lymphoid Cell Neoplasm

In brief

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.

You may not qualify if…

Failure of research participant to understand the basic elements of the protocol and/or the risks/benefits of participating in this pilot study. A legal guardian may substitute for the research participant
Research participants receiving any other investigational agents
Research participants with presence of other active malignancy within 2 years of study entry. Participants with history of prior malignancy treated with curative intent who achieved complete remission (CR) more than 2 years before study entry are eligible. This exclusion rule does not apply to non-melanoma skin tumors and in-situ cervical cancer
Research participants having any uncontrolled illness including ongoing or active infection. Research participants with known active hepatitis B or C infection; research participants who are human immunodeficiency virus (HIV) seropositive based on testing performed within 4 weeks of enrollment; research participants with any signs or symptoms of active infection, positive blood cultures, or radiological evidence of infections
Refusing to use contraception up to 90 days post-HCT
Pregnant and/or breast feeding if a female recipient
Lactose intolerance or intolerance to milk products
In the opinion of the principal investigator (PI), the participant has a condition that will preclude them from complying with study treatment
