The purpose of this healthy volunteers drug-drug interaction study is to assess the CYP1A2 and CYP3A4 perpetrator interaction potential and CYP1A2 victim potential of TEV-56286 (anle138b).

This a 2-part DDI study that will assess the CYP1A2 and CYP3A4 perpetrator interaction potential of TEV-56286 single dose and multiple dose, using caffeine and midazolam as substrates and CYP1A2 victim potential of TEV-56286 (anle138b) at steady state induction using fluvoxamine as inhibitor [1,2].The estimated time from screening until the follow-up visit is approximately up to 8 weeks for each subjects.

Inclusion Criteria:

• Healthy males or healthy females of non-childbearing potential
• Must provide written informed consent for participation in the study and must be able to understand the study requirements
• Body mass index (BMI) 18.5 to 32.0 kg/m2.
• Must agree to adhere to the contraception requirements defined in the study protocol.

Exclusion Criteria:

• Serious adverse reaction or serious hypersensitivity to any drug or formulation excipients e.g. fluvoxamine, caffeine, midazolam or benzodiazepines or any of its excipients, or a known drug hypersensitivity idiosyncratic reaction to TEV-56286, or one of its excipients
• History of clinically significant cardiovascular, renal, hepatic, dermatological, chronic respiratory or gastrointestinal disease, neurological or psychiatric disorder, metabolic diseases or a history of any illness that, in the opinion of the investigator, might pose additional risk to the subject by participation in the study or confound the results of the study

• Major trauma or surgery in the 2 months before screening or at any time between screening and Day 1, or surgery scheduled during the study or follow up period
• History of malignancy or treatment of malignancy in the last 5 years
• History of suicidal ideation with an intent and/or plan and behaviour based upon either clinical history or source documents
• Personal or family history of arrhythmia, sudden unexplained death at a young age (before 40 years) in a first-degree relative, or long QT syndrome, or a personal history of syncope or previous treatment for high blood pressure (BP). Abnormality of 12-lead ECG that may, in the opinion of the investigator, interfere with study participation
• Any procedure or disorder that may interfere with drug absorption, distribution, metabolism, or excretion
• Clinically significant abnormal clinical chemistry, haematology or urinalysis as judged by the investigator.
• Subjects who have received any IMP in a clinical research study within the 90 days prior to Day 1, or less than 5 elimination half-lives prior to Day 1, whichever is longer
• Subjects who are taking, or have taken, any prescribed or over-the-counter drug or herbal remedies in the 14 days before study medication administration or within 5 half-lives whichever is longer.
• Subjects who are taking, or have taken hormonal contraceptives (e.g., oral, patch, injectable or intrauterine device) hormone replacement therapy (HRT) or a long-acting injectable hormonal within 4 weeks prior to first dose of IMP
• Subjects who are taking, or have taken any inducer of CYP 1A2, CYP3A4 within 28 days prior to Day -2
• History of any drug or alcohol abuse in the past 2 years
• Current smokers and those who have smoked within the last 12 months or has a positive urine cotinine test
• Current users of e-cigarettes and nicotine replacement products and those who have used these products within the last 12 months
