About

The study will assess the safety and tolerability, pharmacodynamic, pharmacokinetic profiles, and food effect of single ascending doses and multiple ascending doses (7 consecutive days) after daily oral administration in healthy male and female subjects.

Full description

This Phase 1, single center, randomized, double-blind, placebo-controlled study will be conducted in 2 parts: the single ascending dosing (SAD) will constitute Part 1 and the multiple ascending dosing (MAD) will constitute Part 2. In Part 1 (ie, SAD) of the study, up to 64 eligible subjects will be randomized with an allocation ratio of 3:1 to receive EHP-101 Liquid or matching placebo within one of up to 8 sequential cohorts; Sentinel subjects (1 receiving EHP-101 Liquid and 1 receiving placebo) will be dosed prior to dosing the remaining 6 subjects to allow for observation of adverse reactions before exposing the Investigational Product (IP) to a greater number of subjects, in the SAD cohorts. In Part 2 of the study, up to 40 eligible subjects will be randomized with an allocation ratio of 4:1 to receive EHP 101 Liquid or matching placebo within one of up to 4 cohorts. Dose-escalations, initiation of a single-dose food effect cross-over investigation and the start of the MAD part of the study will be coordinated by a Safety Review Committee (SRC) following review of available safety data.

Inclusion criteria

• Healthy male or female subjects ≥ 18 to ≤ 65 years of age.
• Body mass index (BMI) range 18 to 34 kg/m².
• Free from any clinically significant abnormality on the basis of medical history, vital signs, physical examination, 12-lead electrocardiogram (ECG), echocardiography, ophthalmologic examinations and tests, and laboratory evaluations at screening and admission, as judged by the Investigator.
• Cardiac Troponin I level below the upper limit of normal, as defined by the manufacturer.
• Ability to understand and the willingness to provide informed consent for participation in the study.
• Ability and willingness, as judged by the Investigator, to comply with all study requirements.

Exclusion criteria

• Any known, documented, or suspected history of:

  1. schizophrenia or other psychotic illness, or diagnosis of schizophrenia in a first-degree relative.
  2. alcohol or substance abuse within the last 2 years before screening or positive test result(s) for alcohol and or drugs of abuse.
  3. Regular alcohol consumption >21 units per week

• Use of nicotine or nicotine-containing products during participation in the study.

• Caffeine consumption is limited to no more than 2 units per day.

• Any known, documented, or suspected hypersensitivity to cannabinoids or any of the excipients of EHP-101 Liquid.

• Use of cannabis or cannabinoid-based medications.

• Abnormal screening 12-lead ECG interpreted by the Investigator to be clinically significant.

• Presence of ophthalmologic abnormalities at baseline, specifically known closed angles, previous laser iridotomy, or severe hypermetropic diagnosis.

• Male subjects who are not surgically sterilized and who do not agree to use condoms in combination with partner use of a highly effective method of contraception. Female subjects of childbearing potential who are not using a highly effective method of contraception, as judged by the Investigator, and who do not consent: i) to use a combined barrier method of contraception and ii) to remain on a highly effective method of contraception while receiving study intervention during the study and for at least 90 days after the end of study treatment.

• Female subjects who are pregnant, lactating, or planning pregnancy during the course of the study and for 12 weeks thereafter.

• Male subjects unwilling to abstain from sperm donation during the study and for 12 weeks thereafter.

• Any evidence or history of hepatitis B, hepatitis C, or human immunodeficiency virus (HIV types 1 and 2) infection.

• Subjects who have received an IP within the 12 weeks before the screening visit.

• Blood donation or loss (eg, ≥ 400 mL) within 3 months before enrollment and unwilling to abstain from blood donation during the study.

• Significant disease or disorder, which, in the opinion of the Investigator or other staff who is directly involved in the study, may either put the subject at risk because of participation in the study or interfere with the subject's ability to participate in the study.

• Intake of any metabolic enzyme-affecting drugs from 30 days prior to Day -1 (ie, Check-in).

• Vaccination within 30 days prior to enrollment.
