数据说明

Conditions: Childhood Acute Lymphoblastic Leukemia in Remission, Childhood Acute Myeloid Leukemia in Remission, Childhood Chronic Myelogenous Leukemia, Childhood Myelodysplastic Syndromes, Chronic Eosinophilic Leukemia, Chronic Myelomonocytic Leukemia, Chronic Neutrophilic Leukemia, de Novo Myelodysplastic Syndromes. PRIMARY OBJECTIVES: I. To determine if topically administered supersaturated calcium phosphate (Caphosol), rinsed orally four times daily at the initiation of conditioning for hematopoietic stem cell transplantation (HSCT), reduces oral mucositis as demonstrated by a decrease in duration of severe oral mucositis (World Health Organization [WHO] grade 3 or 4), compared to placebo. SECONDARY OBJECTIVES: I. To determine whether Caphosol administration, when compared to placebo, reduces oral mucositis as demonstrated by a decrease in incidence of severe oral mucositis (WHO grade 3 or 4); severity of mucositis according to mouth pain categorical rating scale and Oral Mucositis Daily Questionnaire (OMDQ); incidence, total dose, and duration of parenteral opioid analgesic use (morphine equivalents); and incidence and duration of total parenteral nutrition (TPN) administration. II. To determine whether Caphosol administration, when compared to placebo, reduces the incidence of febrile neutropenia and invasive bacterial infections. III. To validate a new pediatric measure of oral mucositis termed the Children’s International Mucositis Evaluation Scale (ChIMES). OUTLINE: This is a multicenter study. Patients are stratified according to conditioning regimen (total-body irradiation (TBI) or melphalan vs neither TBI nor melphalan) and hematopoietic stem cell transplantation (HSCT) (autologous vs allogeneic). Patients are randomized to 1 of 2 treatment arms. ARM I: Patients rinse and gargle with supersaturated calcium phosphate rinse over 1 minute four* times daily (QID) beginning on the first day (about day -7) of the conditioning regimen. ARM II: Patients rinse and gargle with placebo over 1 minute QID* beginning the first day (about day -7) of the conditioning regimen. NOTE: * Patients who reach WHO grade 3 or 4 mucositis have the option to request a total of
