This randomized phase III trial is studying APF530 and dexamethasone to see how well they work compared with palonosetron and dexamethasone in preventing nausea and vomiting in patients receiving chemotherapy for cancer.
OBJECTIVES:

Primary

Compare the overall activity and effects of APF530 versus palonosetron hydrochloride in combination with dexamethasone for prophylaxis of acute- or delayed-onset, chemotherapy-induced nausea and vomiting in patients undergoing moderately or highly emetogenic chemotherapy for cancer.

Secondary

Evaluate the safety, tolerability, and efficacy of APF530, in terms of prevention of acute- and delayed-onset nausea and vomiting, in these patients.
Gather the pharmacokinetics of APF530 in a subset of patients during chemotherapy course 1.
Gather ECG data (using 24-hour Holter monitoring) in a subset of patients during chemotherapy course 1.

OUTLINE: This is a randomized, placebo-controlled, double-blind, parallel-group, multicenter study. Patients are stratified according to emetogenicity of scheduled chemotherapy (moderate-risk [level 3 or 4] vs high-risk [level 5]). Patients are randomized to 1 of 3 treatment arms (I, II, and III). Patients who are randomized to receive palonosetron hydrochloride during chemotherapy course 1 (arm I) are then re-randomized to 1 of 2 treatment arms (II and III) after chemotherapy course 1 to receive treatment during chemotherapy courses 2-4.

Patients receive palonosetron hydrochloride or APF530 and/or placebo 30-60 minutes before the start of chemotherapy. Patients receive dexamethasone 30-90 minutes before the start of chemotherapy.

Arm I: Patients receive palonosetron hydrochloride IV, placebo subcutaneously (SC), and dexamethasone IV on day 1 of chemotherapy course 1. Patients in the high-risk (level 5) stratum also receive oral dexamethasone on days 2-4 of all treatment courses.
Arm II: Patients receive APF530 SC, placebo IV, and dexamethasone IV on day 1 of chemotherapy course 1. Patients then receive APF530 SC and dexamethasone IV on day 1 of chemotherapy courses 2-4. Patients in the high-risk (level 5) stratum also receive oral dexamethasone as in arm I.
Arm III: Patients receive APF530 SC at a higher dose, placebo IV, and dexamethasone IV on day 1 of chemotherapy course 1. Patients then receive APF530 SC (at the same higher dose) and dexamethasone IV on day 1 of chemotherapy courses 2-4. Patients in the high-risk (level 5) stratum also receive oral dexamethasone as in arm I.

A subset of patients undergo blood collection periodically during study for analysis of plasma APF530 concentration.

Quality of life is assessed on day 5 after completion of chemotherapy course 1.

After completion of study treatment, patients are followed at approximately 30 days.

Patients receive palonosetron hydrochloride IV, placebo subcutaneously (SC), and dexamethasone IV on day 1 of chemotherapy course 1. Patients in the high-risk (level 5) stratum also receive oral dexamethasone on days 2-4 of all treatment courses.

Arm II Experimental

Patients receive APF530 SC, placebo IV, and dexamethasone IV on day 1 of chemotherapy course 1. Patients then receive APF530 SC and dexamethasone IV on day 1 of chemotherapy courses 2-4. Patients in the high-risk (level 5) stratum also receive oral dexamethasone as in arm I.

Arm III Experimental

Patients receive APF530 SC at a higher dose, placebo IV, and dexamethasone IV on day 1 of chemotherapy course 1. Patients then receive APF530 SC (at the same higher dose) and dexamethasone IV on day 1 of chemotherapy courses 2-4. Patients in the high-risk (level 5) stratum also receive oral dexamethasone as in arm I.
