Condition(s) targeted: Cancer

Intervention: aprepitant (Drug); dexamethasone (Drug); ondansetron (Drug); placebo (Drug)

Phase: N/A

Status: Completed

Sponsored by: OHSU Knight Cancer Institute

Official(s) and/or principal investigator(s):
Joseph Bubalo, PharmD, Principal Investigator, Affiliation: OHSU Knight Cancer Institute


RATIONALE: Antiemetic drugs, such as aprepitant, ondansetron, and dexamethasone, may help lessen or prevent nausea and vomiting in patients undergoing a stem cell transplant. PURPOSE: This randomized clinical trial is studying aprepitant, ondansetron, and dexamethasone to see how well they work compared to placebo, ondansetron, and dexamethasone in preventing nausea and vomiting in patients who are undergoing a stem cell transplant.

Clinical Details

Official title: A Pilot Study of Aprepitant vs. Placebo Combined With Standard Antiemetics for the Control of Nausea and Vomiting During Hematopoietic Cell Transplatation(HCT)

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Supportive Care

Primary outcome: Number of Emesis Free Participants During the Study Period.

Secondary outcome:

Safety in Transplant Population

Effects on Nausea, Appetite and Taste Changes

Pharmacokinetic Interaction

Detailed description: OBJECTIVES: Primary

- Compare the efficacy of standard antiemetic therapy comprising ondansetron and

dexamethasone combined with either aprepitant or placebo in controlling nausea and vomiting, as determined by the number of retch/emesis-free days, in patients undergoing hematopoietic stem cell transplantation. Secondary

- Determine the safety of aprepitant in these patients.

- Compare nausea, appetite, taste changes, nutritional intake, and mucositis in patients

treated with these regimens.

- Determine the pharmacokinetics of cyclophosphamide, carboxyethylphosphoramide mustard,

hydroxycyclophylamide, and aprepitant in these patients. OUTLINE: This is a randomized, placebo-controlled, single-blind, pilot study. Patients are randomized to 1 of 2 treatment arms.

- Arm I: Beginning on the first day of conditioning chemotherapy, patients receive oral

aprepitant once daily and standard antiemetic therapy comprising oral or IV ondansetron and oral dexamethasone.

- Arm II: Patients receive oral placebo once daily and standard antiemetic therapy as in

arm I. In both arms, treatment continues until day 4 after stem cell transplant in the absence of unacceptable toxicity. After completion of study therapy, patients are followed until day 18. PROJECTED ACCRUAL: A total of 40 patients (20 per treatment arm) will be accrued for this study.
