evaluate bioequivalence of palonosetron (0.25mg/5ml)

Conditions: Chemotherapy-induced Nausea and Vomiting, Prophylaxis

Summary: a randomized, single-dose, two-way crossover study to evaluate bioequivalence of two formulations of palonosetron after intravenous administration of palonosetron in healthy volunteers under fasting conditions.


Eligibility criteria:
inclusion criteria: 1. healthy adult male or female subjects between 20-45 years of age (inclusive) at the screening visit. 2. body mass index (bmi) between 18 and 27 kg/m2 (not inclusive) at the screening visit. 3. acceptable medical history and physical examination including: * no particular clinically significant abnormalities in ecg results within six months prior to period i dosing. * no particular clinical significance in general disease history within two months prior to period i dosing. 4. acceptable biochemistry determinations (within normal limits or considered by the investigator or physician to be of no clinical significance) within two months prior to period i dosing, which includes ast (sgot), alt (sgpt), γ-gt, alkaline phosphatase, total bilirubin, albumin, glucose, bun, uric acid, creatinine, total cholesterol and triglyceride (tg). 5. acceptable hematology (within normal limits or considered by the investigator or physician to be of no clinical significance) within two months prior to period i dosing, which includes hemoglobin, hematocrit, red blood cell count, white blood cell count with differentials and platelets. 6. acceptable urinalysis (within normal limits or considered by the investigator or physician to be of no clinical significance) within two months prior to period i dosing, which includes ph, blood, glucose, ketones, bilirubin and protein. 7. female of childbearing potential practicing an acceptable method of birth control for the duration of the study. 8. have signed the written informed consent to participate in the study. exclusion criteria: 1. a clinically significant disorder involving the cardiovascular, respiratory, hepatic, renal, urinary tract, gastrointestinal, immunologic, hematologic, endocrine or neurologic system(s) or psychiatric disease. 2. a clinically significant illness or surgery within four weeks prior to period i dosing. 3. history of gastrointestinal obstruction, inflammatory bowel disease, gallbladder disease, pancreas disorder over last two years or history of gastrointestinal tract surgery over last five years. 4. history of kidney disease or urination problem over last two years deemed by the investigator to be clinically significant. 5. known or suspected history of drug abuse within lifetime. 6. history of alcohol addiction or abuse within last five years or use of more than 7 units of alcohol per week within two weeks prior to dosing.
