Chronic Myelomonocytic Leukemia Clinical Trial
Official title:
A Randomized Double Blinded Trial of Topical Caphosol to Prevent Oral Mucositis in Children Undergoing Hematopoietic Stem Cell Transplantation
This randomized phase III trial is studying how well Caphosol rinse works in preventing mucositis in young patients undergoing autologous or donor stem cell transplant. Supersaturated calcium phosphate (Caphosol) rinse may be able to prevent mucositis, or mouth sores, in patients undergoing stem cell transplant.
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 6
rinses daily.
In both arms, treatment continues until day 20 post-transplantation OR until mucositis
resolves to WHO grade =< 2 for two consecutive days OR on day 12 in patients who do not
experience oral mucositis of at least WHO grade >= 1. Patients are assessed daily by trained
healthcare professionals using the Oral Mucositis Daily Questionnaire (OMDQ), the Pain Rating
Scale, the WHO Mucositis Scale, and the Children's International Mucositis Evaluation Scale
(ChIMES) from day -1 and continuing until day 20. Patients are also observed for the
incidence of total dose and duration of parenteral opioid analgesic use, duration of total
parenteral nutrition (TPN) administration, febrile neutropenia, and invasive bacterial
infections.
After completion of study therapy, patients are followed up for 30 days.
