Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This Phase I clinical study is a randomized, double-blind, placebo-controlled, parallel-design study to thoroughly assess the safety profile and PK properties of J147 in healthy subjects and to perform a preliminary assessment of the effect of food on safety and PK parameters of J147. The study will include single ascending dose (SAD) in healthy young and elderly subjects.

Approximately 64 subjects may be included in the study, with an additional 24 to be added depending on the emerging data.

Six cohorts of 8 healthy young male subjects and 2 cohorts of 8 healthy elderly male and female subjects are planned. Depending on emerging safety, tolerability and PK data, 2 additional cohorts of 8 healthy young male subjects in each cohort and 1 additional cohort of 8 elderly male and female subjects may be enrolled.

In each cohort, 6 subjects will be randomized to receive a single dose of J147 orally and 2 subjects will be randomized to receive a matching dose of placebo.

All cohorts will consist of 2 sentinel subjects of whom 1 subject will receive J147 and 1 subject will receive matching placebo. The remaining 6 subjects of whom 5 subjects will receive J147 and 1 subject will receive matching placebo will be dosed at least 24 hours following the sentinel subjects.

Healthy elderly subjects will receive doses that have been found to be safe in healthy young subjects.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

SEQUENTIAL

Subjects will receive a single dose of J147 or placebo in a fasted state. The dose levels are planned to be administered in ascending order. Progression to the next dose level, and dose selection, will be based on all available safety and tolerability data up to at least 48 hours post-dose and available PK data (up to at least 24 hours post-dose) from a minimum of 6 subjects (J147 n ≥4) in the preceding dose cohort. Healthy elderly subjects will receive doses that have been found to be safe in healthy young subjects.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Provide voluntarily agreement to participate in this study and signs an IRB/IEC-approved informed consent prior to performing any of the screening procedures
* Healthy male subjects, between 18 to 50 years of age, inclusive, at the time of signing the informed consent; OR, Healthy male and female subjects, between 60 to 85 years of age, inclusive, at the time of signing the informed consent
* If male, subjects with partners of child bearing potential must be practicing abstinence, part of an abstinent life style or agree to use a highly effective contraception method during the intervention period and for at least 3 months after the last dose of study medication and refrain from donating sperm during this period. Because of the unacceptable failure rate of barrier (chemical and/or physical) methods, the barrier method of contraception must only be used in combination with a highly effective method. Post coital methods of contraception are not permitted.
* If female, must not be pregnant, must not be lactating, and must be of non-childbearing potential (surgically sterile \[hysterectomy or bilateral tubal ligation\] or postmenopausal ≥ 1 year.
* Body mass index (BMI) between 18.0 and 30.0 kg/m2, inclusive, at screening with a weight of at least 50 kg
* Nonsmokers (or other nicotine use) as determined by history (no nicotine use over the past year) and by urine cotinine concentration (\< 200 ng/mL) at the screening visit and admission

Exclusion Criteria

* Has clinically significant history or evidence of cardiovascular, endocrine, hematologic, immune, gastrointestinal, genitourinary or other body system disease as determined by an Investigator
* Has clinically significant history or evidence of disease or dysfunction in neurological or psychiatric system that is likely to affect the results of the study in the opinion of an Investigator
* Has any disorder that would interfere with the absorption, distribution, metabolism or excretion of drugs
* Subject has any concurrent disease or condition that, in the opinion of the Principal Investigator, would make the subject unsuitable for participation in the clinical study
* Has positive test for hepatitis B surface antigen (HBsAg), hepatitis C antibody (HCV) or human immunodeficiency virus (HIV) antibodies
* Has a urine blood test for ethanol or cotinine at the screening visit or admission
* Has a positive urine drug test (e.g., cocaine, amphetamines, barbiturates, opiates, benzodiazepines, cannabinoids) at the screening visit or admission

* Is unwilling to or has not avoided consumption of grapefruit, grapefruit juice, Seville oranges, Seville orange marmalade or other products containing grapefruit or Seville oranges within 14 days of dosing with study medication
* Has history of alcohol and/or illicit drug abuse within 1 year of entry or is unwilling to avoid use of alcohol or alcohol-containing foods, medications or beverages, within 48 hours prior to admission until discharge from the clinical unit
* Has donated blood (\> 500 mL) or blood products within 30 days prior to first day of dosing
* Requires treatment with any medication, prescription or over-the-counter (OTC) medications (including vitamins \[mega doses\], dietary supplements or herbal medications), prescription medications within 14 days prior to administration of study medication. By exception, acetaminophen ≤ 1000 mg per day and vitamin products at recommended daily doses are permitted
* Has received any known hepatic or renal clearance altering agents (e.g., erythromycin, cimetidine, barbiturates, phenothiazines or herbal/plant-derived preparations such as St. John's wort) for a period of 30 days prior to dosing
* Has used an investigational drug within 30 days prior to screening
* Has a history of hypersensitivity or allergies to J147, any components of formulated J147, or any drug within the same class; minor drug allergies to a drug in another drug class may be approved by an Investigator if not considered of clinical relevance
* Has clinically significant abnormal vital signs, 12-lead ECGs, physical examination, clinical laboratory, or other safety variable, as judged by an Investigator
