The Prophylactic Use of Loratadine for Granulocyte-Colony Stimulating Factor (G-CSF) Induced Bone Pain in Multiple Myeloma Patients Undergoing Stem Cell Mobilization

Description

This early phase I trial studies how well loratadine works in reducing granulocyte-colony stimulating factor (G-CSF) induced bone pain in patients with multiple myeloma who are undergoing stem cell mobilization. Loratadine is an antihistamine that may help to reduce or control bone pain during the process of stem cell collection in patients with multiple myeloma.PRIMARY OBJECTIVE: I. To evaluate the efficacy of the second-generation antihistamine, loratadine, as prophylaxis for filgrastim (i.e., Neupogen, Zarxio) induced bone pain during stem cell mobilization in multiple myeloma patients. SECONDARY OBJECTIVES: I. To examine the frequency and quantity of supportive analgesic medications needed in addition to loratadine or placebo for filgrastim induced bone pain. II. To identify risk factors associated with developing filgrastim induced bone pain. OUTLINE: Patients are randomized to 1 of 2 cohorts. COHORT I: Beginning 5 days before the first dose of standard of care filgrastim, p
