Intervention: dexamethasone (Drug); dronabinol (Drug); palonosetron hydrochloride (Drug); placebo (Other)

Phase: Phase 3

RATIONALE: Antiemetic drugs, such as dexamethasone, palonosetron, and dronabinol may help lessen or prevent nausea and vomiting caused by chemotherapy. It is not yet known whether giving dronabinol together with palonosetron and dexamethasone is more effective than giving palonosetron and dexamethasone in preventing nausea and vomiting caused by chemotherapy.

PURPOSE: This randomized phase III trial is studying giving dronabinol together with palonosetron and dexamethasone to see how well they work compared to giving palonosetron and dexamethasone alone in preventing nausea and vomiting in patients undergoing chemotherapy for cancer.

Official title: Randomized, Double-Blind, Placebo-Controlled Trial of Palonosetron/Dexamethasone With or Without Dronabinol for the Prevention of Chemotherapy-Induced Nausea and Vomiting After Moderately Emetogenic Chemotherapy

Study design: Allocation: Randomized, Masking: Double-Blind, Primary Purpose: Supportive Care

Primary outcome: Total protection (i.e., no vomiting, no rescue therapy, and no nausea as indicated by responses to the Daily Assessment of Nausea and Vomiting questionnaire during the overall [0-120 hour] period)

Secondary outcome:

No vomiting, no significant nausea, and no nausea evaluated for the acute (0-24 hour), delayed (24-120 hour), and overall (0-120 hour) periods

Complete protection and complete response for the acute, delayed, and overall periods

Detailed description: OBJECTIVES:

- To determine whether dronabinol can add significantly to the antiemetic protection

provided by a standard palonosetron hydrochloride and dexamethasone regimen for patients receiving moderately emetogenic chemotherapy.

- To determine the tolerability of dronabinol when added to a regimen of dexamethasone

and palonosetron hydrochloride administered for the prevention of acute and delayed nausea and vomiting caused by moderately emetogenic chemotherapy.

- To determine tolerability, in terms of treatment-limiting toxicities, observed with the

three-drug combination.

OUTLINE: This is a multicenter study. Patients are stratified according to study center. Patients receive scheduled chemotherapy (cyclophosphamide and/or doxorubicin hydrochloride) beginning on day 1. Patients are randomized to 1 of 2 treatment arms.

- Arm I: Patients receive palonosetron hydrochloride IV and dexamethasone IV 30 minutes

before chemotherapy administration on day 1. Patients also receive oral dronabinol 3 times a day for 5 days beginning 30 minutes before chemotherapy administration on day 1.

- Arm II: Patients receive palonosetron hydrochloride and dexamethasone as in arm I.

Patients also receive an oral placebo 3 times a day for 5 days beginning 30 minutes before chemotherapy on day 1.

In both arms, treatment continues in the absence of nausea or vomiting within 24 hours after initiation of chemotherapy.

Patients complete a Daily Assessment of Nausea and Vomiting questionnaire after the administration of chemotherapy on days 1-5.

Patients are followed at the completion of course 1 of chemotherapy (days 14-28).

Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

DISEASE CHARACTERISTICS:
