A Clinical Study in Healthy Women Which Aims to Explore the Intestinal Uptake of Two Different Tablets of GRTA9906 Into the Body and the Effect of Food on it

• Status: Completed
• Trial end date: 2003-12-11
• Target enrollment: 0
• Participant gender: Female

Summary

The aim of this clinical study in healthy women is to explore the intestinal uptake (bioavailability) of two different tablets of GRTA9906 (formulations) into the body and the effect of food on it. The intake of food may considerably influence the bioavailability, either by interaction with the compound itself or, if a prolonged release (PR) formulation is used, with the components of the tablet-matrix. For these reasons, the relative bioavailability and the effect of food on the bioavailability of GRTA9906 given as PR tablets compared to immediate release (IR) capsules will be assessed in this study.

During the 4 periods of the study, each participant will receive two 60 mg GRTA9906 PR matrix tablets and two 60 mg GRTA9906 IR capsules under fed conditions (after consumption of a high-fat and high-calorie test meal) and fasting conditions (10 hours before dosing until 4.5 hours after dosing). In each period, the participant will receive the investigational product once.

Criteria

Inclusion Criteria:

• Female Caucasian volunteers aged 18 - 55 years.

• Body mass index between 18 and 29 kilograms per square meter inclusive.

• Good physical and mental health status (no current acute illness) determined on the basis of the medical history and a general clinical examination.

• Normal supine blood pressure (systolic blood pressure greater than or equal to 90 Millimeter mercury (mmHg) and less than or equal to 145 mmHg, diastolic blood pressure greater than or equal to 45mmHg and less than or equal to 90 mmHg) and pulse (greater than or equal to 45 and less than or equal to 90 beats per minute).

• Electrocardiogram (12 lead) considered as normal by the Investigator.

• Results of laboratory tests within the normal ranges for the testing laboratory. The Investigator may include a participant having values outside the accepted range if, in his/her opinion, these values are of no clinical relevance. The decision will be justified.

• Participants giving written consent to participate in this trial.

• Negative pregnancy test (females of childbearing potential only).

• Adequate contraception (females of childbearing potential only; adequate contraception is defined as any form of hormonal contraception or intra-uterine device that needs to be in place for a period of at least 2 months prior to screening. Additional barrier contraception must be used for the duration of the study, defined as from the time of screening to the post-study medical examination, and for at least one full month thereafter. A single barrier method alone or abstinence alone is not acceptable. Women of non-childbearing potential may be included if surgically sterile or post-menopausal for at least 2 years).

• Must be able to tolerate high-fat and high-calorie study-meal.

Exclusion Criteria:

• Diseases and functional disorders of the gastrointestinal tract, hepatobiliary system, renal system or cardiovascular system including marked repolarisation abnormality (e.g. suspicious or definite congenital long QT syndrome) or co-medication that is known to influence cardiac repolarisation substantially.

• Malignancy.

• History of orthostatic hypotension.

• Positive human immunodeficiency virus HIV1/2-antibodies, hepatitis B surface-antigen (HBs), hepatitis B core-antibodies (HBc), Hepatitis C virus (HCV) antibody tests at the prestudy medical examination.

• Drug allergy.

• Bronchial asthma.

• Participation in another clinical study in the last three months before starting this study (exception: characterisation of metaboliser status).

• Blood donation (more than 100 milliliter) in the last three months before the start of the study.

• Evidence of alcohol, medication or drug abuse.

• Positive drug abuse screening test.

• Extremely unbalanced diet (in the opinion of the investigator).

• Excessive consumption of food or beverages containing caffeine or other xanthines (more than five cups of coffee or equivalent per day).

• Smoking of more than 20 cigarettes per day.

• Known or suspected of not being able to comply with the study protocol.

• Neurotic personality, psychiatric illness, or suicide risk.

• History of seizures or at risk (i.e. head trauma, epilepsy in family anamnesis, unclear loss of consciousness).

• Pregnant or breastfeeding.
