About

Characterisation of relative bioavailability of Diena (Test) in comparison to Valette® (Reference) after single dose administration under fasting conditions
Assessment of bioequivalence of Test vs. Reference after single dose administration under fasting conditions, determined by use of area under the concentration time curve AUC0-tlast and maximum concentration Cmax obtained for ethinylestradiol (EE) and dienogest (DNG)
Descriptive characterisation of safety and tolerability of the investigational products in the study population

Full description

The aims of this study were to characterise relative bioavailability of Diena (Test) in comparison to Valette® (Reference) after single dose administration under fasting conditions and to assess bioequivalence of Test vs. Reference after single dose administration under fasting conditions, determined by use of area under the concentration time curve AUC0-tlast and maximal concentration Cmax obtained for ethinylestradiol (EE) and dienogest (DNG). Furthermore, a descriptive characterisation of safety and tolerability of the investigational products in the study population was performed.

existing hepatic and/or renal diseases and/or pathological findings, which might interfere with the safety, tolerability, absorption and/or pharmacokinetics of the active ingredient
existing gastrointestinal diseases and/or pathological findings, which might interfere with the safety, tolerability, absorption and/or pharmacokinetics of the active ingredient
history of relevant CNS and/or psychiatric disorders and/or currently treated CNS and/or psychiatric disorders
pathological ECG (12 standard leads) which might interfere with the safety of the active ingredient

regular intake of caffeine containing food or beverages of ≥ 500 mg per day
blood donation or other blood loss of more than 400 ml within the last two months prior to individual enrolment of the subject
participation in a clinical trial during the last two months prior to individual enrolment of the subject
regular treatment with any systemically available medication (except usual replacement therapy with L-thyroxine)
subjects, who report a frequent occurrence of migraine attacks
use of hormonal preparations within 6 weeks (oral, transdermal, vaginal), 2 months (intramuscularly administered depot preparations used once per month) or 6 months (intramuscularly administered depot preparations used once per 3 month) before pre-study examination

For female subjects with childbearing potential only:
positive pregnancy test at pre-study examination
pregnant or lactating women
female subjects who do not agree to apply adequate non-hormonal and highly effective contraceptive methods as defined in Note for Guidance on Non-Clinical Safety Studies for the Conduct of Human Clinical Trials for Pharmaceuticals (CPMP/ICH/286/95, modification), November 2000 Administrative reasons
subjects suspected or known not to follow instructions
subjects who are unable to understand the written and verbal instructions, in particular regarding the risks and inconveniences they will be exposed to during their participation in the study The exclusion criteria are chosen to assure that subjects with specific risks for administration of the investigated medicinal products and subjects with conditions, which may have an impact on pharmacokinetic parameters, cannot be included.
