Open-label Study to Evaluate the Effects of NST-1024 on the PK of Multiple Drugs in Heathy Subjects

Study Overview
=================
Brief Summary
-----------------
Phase 1, open label study to evaluate the effects of NST-1024 on the pharmacokinetics (PK) of caffeine (and paraxanthine), flurbiprofen, omeprazole, metoprolol, and midazolam (and 1-hydroxymidazolam) in healthy male and female subjects.

Detailed Description
-----------------
Up to 21 subjects will be enroled to ensure that 18 subjects complete the study. All subjects will receive each of the following treatments: Day 1: single oral dose of 100 mg caffeine, 50 mg flurbiprofen, 20 mg omeprazole, 100 mg metoprolol, and 2.5 mg midazolam Days 8 to 22: oral doses of 200 mg NST-1024 qd multiple-dose regimen Day 8: single oral dose of 100 mg caffeine, 50 mg flurbiprofen, 20 mg omeprazole, 100 mg metoprolol, and 2.5 mg midazolam coadministered with an oral dose of 200 mg NST-1024 Day 21: single oral dose of 100 mg caffeine and 2.5 mg midazolam coadministered with an oral dose of 200 mg NST-1024.

Eligibility Criteria
-----------------
Inclusion Criteria: Males or females, of any race, between 18 and 65 years of age, inclusive. Body mass index between 18.0 and 32.0 kg/m2, inclusive. In good health, determined by no clinically significant findings from medical history, 12 lead ECG, vital signs measurements, and clinical laboratory evaluations (congenital nonhaemolytic hyperbilirubinemia [eg, suspicion of Gilbert's syndrome based on total and direct bilirubin] is not acceptable) at screening and/or check in and from the physical examination at check-in, as assessed by the investigator (or designee). Females will not be pregnant or lactating, and females of childbearing potential and males will agree to use contraception as detailed in Appendix 4. Able to comprehend and willing to sign an ICF and to abide by the study restrictions Exclusion Criteria: Significant history or clinical manifestation of any metabolic, allergic, dermatological, hepatic, renal, haematological, pulmonary, CV, gastrointestinal, neurological, respiratory, endocrine, or psychiatric disorder, as determined by the investigator (or designee). History of febrile illness within 1 week prior to the first dose. History of significant hypersensitivity, intolerance, or allergy to any drug compound, food, or other substance, unless approved by the investigator (or designee). History of stomach or intestinal surgery or resection that would potentially alter absorption and/or excretion of orally administered drugs (uncomplicated appendectomy and hernia repair will be allowed). Confirmed (eg, 2 consecutive measurements) systolic blood pressure >160 or <80 mmHg, diastolic blood pressure >90 or <45 mmHg, and pulse rate >100 or <40 beats per minute. Positive hepatitis panel and/or positive human immunodeficiency virus test Administration of a coronavirus disease 2019 vaccine in the past 30 days prior to dosing. Use or intend to use any medications/products known to alter drug absorption, metabolism, or elimination processes, including over-the-counter and herbal medication, within 30 days prior to dosing, unless deemed acceptable by the investigator (or designee). Use or intend to use any prescription medications/products other than hormone replacement therapy, oral, implantable, transdermal, injectable, or intrauterine contraceptives within 14 days prior to dosing, unless deemed acceptable by the investigator (or designee). Participation in a clinical study involving administration of an investigational drug (new chemical entity) in the past 90 days prior to dosing. Alcohol consumption of >21 units (males) and >14 units (females) per week. One unit of alcohol equals ½ pint (285 mL) of beer or lager, 1 glass (125 mL) of wine, or 1/6 gill (25 mL) of spirits. Receipt of blood products within 2 months prior to check in.
