Bioavailability is linked to drug solubility and intestinal permeability. A promising method to increase drug solubility, and therefore bioavailability, is the formulation of the drug as hot-melt extruded amorphous solid dispersion drug delivery systems, which have been shown to potentially increase in vivo and clinical bioavailability.The mechanisms that lead to increased bioavailability are not understood completely.\n\nIn this study, investigators investigate the role of amorphous solid dispersions and thereof generated drug-rich particles on bioavailability and their in vivo behaviour. Investigators do so by administering the delivery system at different stages in the process of drug availability.\n\nPrimary objectives are the pharmacokinetic analysis of a model formulation using efavirenz as model drug tracer in human.\n\n* Comparison of pharmacokinetic parameters such as relative bioavailability and further parameters derived from pharmacokinetic analysis and corresponding interpatient variabilities.\n* Mechanistic analysis of pharmacokinetic data, such as determination of in vivo dissolution from the solid formulation (study product 1) to drug rich particles (study product 2) using numerical deconvolution or analysis of the effect of drug rich particles on the absorption rate of Efavirenz in comparison to the solution of Efavirenz (study product 3).\n\nSecondary objectives are the comparison of obtained pharmacokinetic profiles to existing data of a conventional formulation with respect to:\n\n* Comparison of pharmacokinetic parameters such as relative bioavailability and further parameters derived from pharmacokinetic analysis and corresponding interpatient variabilities.\n* Extrapolation investigation from in vitro to in vivo data.\n\nSafety objectives are the recording of any side effects or tolerability issues of the investigational drug delivery system.'}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['ADULT'], 'maximumAge': '50 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Full mental and legal capacity, ability and willingness to understand and comply to study interventions and restrictions and to communicate with study personnel.\n* Informed Consent, documented by signature (Informed Consent Form).\n* Physically and mentally healthy male participants, age of 18 to 50 years.\n* Body mass index (BMI) of 18.0 to 29.9 kg/m2, systolic blood pressure (SBP) 100-145 mmHg, diastolic blood pressure (DBP) 50- 90 mmHg and heart rate (HR) 45-90 bpm, measured on the leading arm, after 5 minutes in supine position, Hemoglobin ≥ 11 g/dl at screening.\n* Normal physical examination, vital signs, laboratory workup (clinical chemistry and hematology), and electrocardiogram (ECG) (in opinion of the principal investigator).\n* Normal renal and liver function based on blood tests (in opinion of the investigator).\n* Medical history that is in line with the eligibility criteria.
