model was developed within the simCYP software and qualified for acoziborole. This study suggested strong interactions with sensitive index substrates of CYP2D6 and CYP3A4.To validate these PB-PK model results, an open-label, non-randomised, three-treatment, one-sequence, two successive periods study with at least 3-day washout between periods was chosen to evaluate clinically the potential impact of acoziborole on plasma exposure of two different sensitive CYP substrates, DXM for CYP2D6 and midazolam for CYP3A4.\n\nAcoziborole will be administered as a single dose, due to the long t1/2 of 360 h in healthy participants.\n\nThe SimCYP simulations showed that the best compromise to maximize the CYP2D6 inhibition and minimize the CYP3A4 induction is when DXM is given 24 to 60 h after acoziborole administration. Therefore, dextromethorphan will be given on Day 1 (in Period 1, without acoziborole) and on Day 14 in Period 2 i.e. 2 days following oral administration of acoziborole.\n\nBased on the PB-PK simulations, the interaction between acoziborole and midazolam should be maximal around Day 8 (due to the activity CYP3A4) following acoziborole administration and sustained for several weeks after. Thus, midazolam will be given on Day 8 (in Period 1 without acoziborole) and on Day 21 in Period 2 i.e. 9 days following oral single administration of acoziborole.'}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['ADULT'], 'maximumAge': '55 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Healthy males.\n* Have the ability to understand and sign a written informed consent form, which must be obtained prior to initiation of study procedures..\n* Age 18 to 55 (inclusive) years of age at the time of signing informed consent.\n* Body mass index (BMI) of 18.0 to 30.0 kg/m2 as measured at screening.\n* Body weight not less than 50 kg.\n* Non-smokers (defined as has not used nicotine-containing products including e-cigarette for at least 3 months prior to the first dose as confirmed by cotinine test).\n* Must be willing and able to communicate and participate in the whole study.\n* Normal blood pressure (BP): Systolic BP (SBP) between 90 and 140 mmHg (inclusive), diastolic BP (DBP) between 45 and 90 mmHg (inclusive), measured after 10 min rest in supine position at screening and first admission (Day -1).\n* A resting heart rate (HR) between 45 and 90 bpm (inclusive), measured after 10 min rest in supine position at screening and first admission (Day -1).\n* ECG recording without clinically significant abnormality, including Fridericia\'s corrected interval between Q and T waves (QTcF) measure of ≤450 msec at screening and first admission (Day -1).\n* Participants must be able to swallow multiple capsules.\n\nExclusion Criteria:\n\n* Have participated in an investigational trial involving administration of any investigational compound within 90 days prior to the study dosing or 5-times the half-life of the drug tested in the previous clinical trial, whichever is longer (time calculated relative to the last dose in the previous clinical trial).\n* History of any drug or alcohol abuse in the past 2 years.\n* Regular alcohol consumption \\>14 units per week and (1 unit = ½ pint beer, or a 25 mL shot of 40% spirit, 1.5 to 2 units = 125 mL glass of wine, depending on type) as confirmed by a positive alcohol breath test at screening or any on admission to the CRW.\n* Participants who do not have suitable veins for multiple venepunctures/cannulations as assessed by the Investigator or delegate at screening.\n* Clinically significant abnormal clinical chemistry, haematology, urinalysis, or clinically significant abnormal physical examination findings as judged by the Investigator.\n* Abnormal renal function (estimate glomerular filtration rate \\[eGFR\\] \\<90 mL/min).\n* Confirmed positive drugs of abuse urine test result (including but not limited to, amphetamines, tetrahydrocannabinol, morphine, methamphetamine, ketamine and benzodiazepines) and at any time during the study.\n* Positive hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (HCV Ab) or human immunodeficiency virus (HIV) results.\n* Positive COVID test at screening and at admission of hospitalisation.\n* COVID-19 full vaccination to be received less than 21 days before Day 1, or start of vaccination, or second dose or booster of vaccination planned during the study period.\n* Clinically significant medical condition and/or abnormal laboratory results that could, in the opinion of the Investigator, jeopardize the participant\'s safety or participation in the study.\n* Known serious adverse reaction or serious hypersensitivity to any drug or the formulation excipients in the past.\n* Presence or history of clinically significant allergy requiring treatment (including asthma, urticaria, clinically significant allergic rash or other severe allergic diathesis), as judged by the Investigator.
