Mayo Clinic4 enrolled

Overview

For patients who receive a hematopoietic cell transplant (HCT), there is a risk of developing a diarrhea secondary to the chemotherapy which we give. Diarrhea is usually harmless in healthy adults; however, in transplant patients, diarrhea can result in dehydration, negative impact on quality of life, and prolonged hospitalization. The purpose of this study was to see if Colesevelam (Welchol) and Serum-derived bovine immunoglobulin-protein (SBI) result in a change in the frequency or consistency of your bowel movements.

This was a randomized, double-blind, placebo-controlled pilot study of SBI, colesevelam, and placebo in patients undergoing autologous HSCT for the clinical care of multiple myeloma. The number of adults undergoing hematopoietic stem cell transplant (HSCT) has grown significantly over the past two decades as a result of the availability of therapies for advanced hematologic and solid tumor malignancies, and the broader selection criteria for eligibility to receive these transplants. Generally, the stem cell transplant procedure consists of administration of chemotherapy and/or radiation therapy to ablate all residual malignancy (called conditioning therapy), followed by intravenous infusion of hematopoietic stem cells to restore bone marrow function. Generally, HSCT has a positive effect on survival, despite serious adverse effects and life-threatening complications. Diarrhea can affect up to 91% of patients receiving autologous or allogeneic HSCT and is identified by 9% of the patients as the single most debilitating adverse effect post-HSCT. Other commonly encountered symptoms are nausea and vomiting (13%) and mouth sores (42%). The impact of diarrhea can be significant and result in dehydration, negative impact on quality of life, prolonged hospitalization with an increased cost and risk, and the diarrhea may be potentially life-threatening.

Outcomes

Primary Outcomes

Stool Frequency

Stool frequency was self reported in a daily bowel pattern diary for 30 days.

Time frame: 30 days

Stool Consistency

The subjects rated their stool consistency using the Bristol Stool Scale. The Bristol Stool Scale is a medical aid designed to classify the form of human feces into seven categories or types. Types 1 and 2 indicate constipation with 3 and 4 being the "ideal stools" especially the latter, as they are the easiest to defecate, and 5-7 tending towards diarrhea.

Time frame: 30 days
