Prevention of Delayed Nausea A Phase III Double-Blind Placebo-Controlled Clinical Trial

OBJECTIVES:

Primary

• Compare the efficacy of palonosetron hydrochloride and dexamethasone followed by prochlorperazine with vs without dexamethasone in preventing delayed nausea in women with chemotherapy-naive breast cancer. (Arms I and IV)
• Determine if palonosetron hydrochloride is more effective than granisetron hydrochloride in controlling treatment-related delayed nausea in these patients. (Arms I and II)
• Determine if the currently recommended antiemetic guideline of aprepitant combined with palonosetron hydrochloride and dexamethasone is the most effective antiemetic regimen for controlling treatment-related delayed nausea in these patients. (Arms III and IV)

Secondary

• Determine if the addition of dexamethasone to prochlorperazine is more effective than the same regimen without dexamethasone for reducing interference with functioning caused by chemotherapy-induced nausea and vomiting in these patients. (Arms I and IV)
• Determine if palonosetron hydrochloride is more effective than granisetron hydrochloride for reducing interference with functioning caused by chemotherapy-induced nausea and vomiting in these patients. (Arms I and II)
• Determine if the currently recommended antiemetic guideline of aprepitant combined with palonosetron hydrochloride and dexamethasone is the most effective antiemetic regimen for reducing interference with functioning due to chemotherapy-induced nausea and vomiting in these patients. (Arms III and IV)

OUTLINE: This is a randomized, placebo-controlled, double-blind, multicenter study. Patients are stratified according to CCOP center and gender. Patients are randomized to 1 of 4 treatment arms. Patients receive study treatment approximately 30 minutes before their scheduled first chemotherapy treatment.

• Arm I: Patients receive palonosetron hydrochloride IV, dexamethasone IV, and oral placebo once on day 1 and oral prochlorperazine 3 times daily and another oral placebo once daily on days 2 and 3.
• Arm II: Patients receive granisetron hydrochloride IV, dexamethasone IV, and oral placebo once on day 1 and oral prochlorperazine 3 times daily and another oral placebo once daily on days 2 and 3.
• Arm III: Patients receive palonosetron hydrochloride IV and dexamethasone IV once on day 1, oral aprepitant once daily on days 1-3, and oral dexamethasone once daily and oral placebo twice daily on days 2 and 3.
• Arm IV: Patients receive palonosetron hydrochloride IV, dexamethasone IV, and oral placebo once on day 1 and oral prochlorperazine 3 times daily and oral dexamethasone once daily on days 2 and 3.

Quality of life is assessed at baseline and on day 4. Nausea and vomiting, fatigue, sleep quality, exercise, and the need for rescue medication (metoclopramide) are assessed on days 1-4.

PROJECTED ACCRUAL: A total of 890 patients will be accrued for this study.

Inclusion criteria

• Have a diagnosis of cancer and be chemotherapy naive.
• Must be scheduled to receive a chemotherapy treatment containing doxorubicin hydrochloride, epirubicin hydrochloride, cisplatin, carboplatin, or oxaliplatin (any dose or schedule) without concurrent radiotherapy or interferon treatment
