Clinical Trials Detalhe

This is a prospective, single-center, randomized, double-blind, placebo-controlled, single-ascending dose (SAD) phase 1 study to evaluate the safety and tolerability of single-ascending doses of BAR 502 in healthy male and female subjects.

Non-Alcoholic Fatty Liver Disease

Inclusion Criteria: 1. Signed informed consent in a language understandable to the subject prior to any study-mandated procedure. 2. Ability to communicate well with the investigator, and to understand and comply with the study requirements. 3. Healthy male or female subject aged between 18 and 55 years (inclusive) at Screening. 4. Body mass index (BMI) of 18.0 to 30.0 kg/m2 (inclusive) at Screening. 5. Systolic blood pressure (SBP) 90-140 mmHg, diastolic blood pressure (DBP) 50-90 mmHg, and pulse rate 45-90 bpm (inclusive), measured on same arm after ≥5 min in the seated position, at Screening. 6. Estimated glomerular filtration rate calculated using the Cockcroft-Gault equation and normalized to an average surface area of 1.73 m2 ≥ 90 mL/min at Screening. 7. If woman, she meets one of the following criteria: 1. is of non-childbearing potential; or 2. is of childbearing potential and agrees to use an accepted non-hormonal or hormonal contraceptive method. If man, he is infertile, vasectomized (i.e. who has received medical assessment of the surgical success) or agrees to abstain from or to use a condom during heterosexual intercourse with a woman of childbearing potential or a pregnant woman, and agrees not to donate sperm, from investigational product administration until at least 90 days after the investigational product administration. In addition, the subject must ensure that his female partner of childbearing potential agrees to consistently and correctly use one of the acceptable contraceptive methods mentioned above, for the same period of time. Exclusion Criteria: \- At screening: 1. Previous exposure to BAR 502. 2. Known hypersensitivity to BAR 502, or any of its excipients. 3. Clinically relevant findings on physical examination. 4. Clinically relevant abnormalities on 12-lead ECG, measured after 5 min in a supine position. 5. Clinically relevant findings in clinical laboratory tests (hematology, clinical chemistry, and urinalysis). 6. QTcF \> 450 ms in males and \> 470 ms in females. 7. Medical history and/or clinical or laboratory evidence of liver or hepatobiliary disease or liver injury as indicated by serum alanine aminotransferase (ALT), AST, gamma-glutamyl transferase (GGT), ALP or total bilirubin levels exceeding the upper limit of normal (ULN). 8. International Normalized Ratio (INR) \> 1.2. 9. Any medical condition, acute, ongoing, recurrent or chronic, that presents a potential risk to the participant and/or that may compromise the objectives of the study. 10. History of major medical or surgical disorders which, in the opinion of the investigator, are likely to interfere with the distribution, metabolism, or excretion of the investigational product. 11. History or clinical evidence of alcoholism or drug abuse within the 3-year period prior to Screening. 12. Previous clinically relevant history of fainting, collapse, syncope, orthostatic hypotension, or vasovagal reactions. 13. Veins unsuitable for intravenous puncture on either arm (e.g., veins that are difficult to locate, access, or puncture, veins with a tendency to rupture during or after puncture). 14. Participation in a clinical study involving investigational product administration within 3 months prior to Screening or in more than 2 clinical studies within 1 year prior to Screening. 15. Excessive methylxanthines consumption, defined as ≥ 800 mg per day. 16. Nicotine intake (e.g., smoking, nicotine patch, nicotine chewing gum, or electronic cigarettes) within 3 months prior to Screening and inability to refrain from nicotine intake from Screening up to End-of-Study (EOS). 17. Loss of 250 mL or more of blood within 3 months prior to Screening. 18. Positive hepatitis B surface antigen (HBsAg) and/or hepatitis C virus antibodies. 19. Positive human immunodeficiency virus (HIV1 and HIV2) antibodies. 20. Positive results in urine drugs-of-abuse, cotinine or ethanol tests. 21. If woman, she is breastfeeding. 22. Positive result in serum pregnancy test. 23. Any other circumstances or conditions, which, in the opinion of the investigator, may affect full participation in the study or compliance with the protocol or may render the subject unsuitable for the study. \- At admission to treatment period: 24. Positive or inconclusive SARS-CoV-2 test result using polymerase chain reaction (PCR) technology prior to Admission to the clinical site. 25. Any recent disease or condition or treatment that, according to the Investigator, would put the subject at undue risk due to study participation or occurred at a timeframe in which may interfere with the study outcomes. 26. Clinically relevant findings on physical examination. 27. Clinically relevant abnormalities on 12-lead ECG, measured after 5 min in a supine position. 28. Clinically relevant findings in clinical laboratory tests. 29. Use of prescription or nonprescription medicinal products, including vitamins, food supplements, herbal supplements (including St John's Wort), within 3 weeks prior to study treatment administration, unless in the Investigator's opinion the medication does not interfere with the pharmacokinetics of study drug or compromise subject safety. 30. Consumption of Seville oranges, pomelo, pomegranate, starfruit or grapefruit products (fresh, canned, or frozen) since Screening. 31. Positive result in urine drugs-of-abuse, cotinine or ethanol tests. 32. Positive result in urine pregnancy test. 33. Any other condition that the investigator considers to render the subject unsuitable for the treatment period.
