Bioequivalence Study Between Levocetirizine Oral Disintegrating Tablet (ODT) and Levocetirizine Immediate Release Tablet (IRT)

• Status: Completed
• Trial end date: 2018-09-17
• Target enrollment: 0
• Participant gender: Male

Summary

This study will be an open-label, randomized 2-way cross-over study to evaluate bioequivalence study between levocetirizine ODT and levocetirizine IRT in healthy Japanese male subjects. Approximately 48 subjects will participate in this study to receive a single dose treatments of levocetirizine ODT 5 milligram (mg) or levocetirizine IRT 5 mg. In Part 1, subjects will randomized in 1:1 ratio (12 in each Period) in Period 1 and 2 to receive single dose of levocetirizine ODT 5 mg with water or single dose levocetirizine IRT 5 mg with water in fasted state. In this part, comparison of bioavailability of levocetirizine ODT and levocetirizine IRT when taken with water in the fasted state will be assessed. In Part 2, subjects will be randomized in 1:1 ratio (12 in each Period) in Period 1 and 2 to receive single dose levocetirizine ODT 5 mg without water or single dose levocetirizine IRT 5 mg with water in fasted state. In this part, comparison of bioavailability of levocetirizine ODT without water and levocetirizine IRT with water in the fasted state will be assessed. There will be at least a 5-day wash out period between the intervention periods. The duration of each subject's participation in each part will be approximately 7 weeks from screening to follow-up.

Criteria

Inclusion Criteria:

• Japanese subjects who are overtly healthy as determined by medical evaluation including medical history, physical examination, laboratory tests, and cardiac monitoring.

• Subjects with body weight of >= 50 kilogram (kg) and body mass index (BMI) within the range of >=18.5 and <25.0 kg per meter square (m^2).

• In male subjects contraceptive use should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.

• Male subjects are eligible to participate if they agree to the following during the intervention period and until the completion of follow-ups: Refrain from donating sperm; Be abstinent from heterosexual or homosexual intercourse as their preferred and usual lifestyle (abstinent on a long term and persistent basis) and agree to remain abstinent; Agree to use a male condom and female partner to use an additional highly effective contraceptive method with a failure rate of <1 percentage per year when having sexual intercourse with a woman of childbearing potential who is not currently pregnant; Agree to use male condom when engaging in any activity that allows for passage of ejaculate to another person.

• Subjects must be non-smokers.

• Subjects capable of giving signed informed consent.

Exclusion Criteria:

• Subjects with history or presence of cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, hematological, or neurological disorders capable of significantly altering the absorption, metabolism, or elimination of drugs; constituting a risk when taking the study intervention; or interfering with the interpretation of data.

• Subjects with abnormal blood pressure as determined by the investigator.

• Subjects with history of allergic rhinitis.

• Subjects with ALT >1.5x upper limit of normal (ULN).

• Subjects with bilirubin >1.5 times ULN (isolated bilirubin >1.5 times ULN is acceptable if bilirubin is fractionated and direct bilirubin <35 percentage).

• Subjects with current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).

• Subjects with QTc >450 millisecond (msec).

• Subjects with past or intended use of over-the-counter or prescription medication including vitamins, diet supplements (including St. John's wort), herbal medications within 14 days prior to first dosing or 5 half-lives (whichever is longer).

• Exposure to more than 4 new chemical entities within 12 months prior to the first dosing day.

• Current enrolment or past participation within 4 months prior to the first dosing day in this or any other clinical study involving an investigational study intervention or any other type of medical research (except for the subjects with no study intervention administered during any of those enrolment or participation).

• The subject with positive serological test for syphilis (Rapid Plasma Reagin [RPR] and Treponema pallidum [TP] antibody tests), Human immunodeficiency virus (HIV) Antigen/Antibody, Hepatitis B surface antigen (HBsAg), Hepatitis C virus (HCV) antibody, or Human T-cell lymphotropic virus type 1 (HTLV-1) antibody at screening.

• Subject with positive pre-study drug screen.

• Subject with regular moderate alcohol consumption within 6 months prior to the study participation defined as: An average weekly intake of >14 units for males. One unit is equivalent to 360 milliliter (mL) of beer, 150 mL of wine or 45 mL of 80 proof distilled of spirits.

• Smoking or history or regular use of tobacco- or nicotine-containing products within 6 months prior to screening.

• Sensitivity to any of the study interventions, or components thereof, or drug or other allergy that, in the opinion of the investigator or Medical Monitor, contraindicates participation in the study.

• History of donation of blood or blood products >= 400 mL within 3 months or >=200 mL within 1 month prior to the first dosing day.
