Brief Summary

The purpose of the study is to provide safety, tolerability, pharmacokinetics and food effects data of a single 8 mg oral dose of EC5026 in healthy subjects.

Detailed Description

This is a single-center, double-blind, placebo-controlled, Phase 1a single dose study fed-fasted study evaluating the safety, tolerability, pharmacokinetics and food effects of a single 8 mg oral dose of EC5026 in healthy male and female subjects. EC5026 is an inhibitor of the soluble Epoxide Hydrolase (sEH) enzyme developed as a first-in-class analgesic for the treatment of pain. This study will help refine the dosing strategy for subsequent multiple-dose studies in healthy subjects and for future clinical trials in patients with pain.

sEH is an enzyme that is downstream in the cytochrome P450 (CYP) pathway of the arachidonic acid (AA) cascade. The sEH enzyme is responsible of metabolizing a class of epoxy-fatty acids known as epoxyeicosatrienoic acids (EETs), which are potent, naturally occurring analgesics. EETs are produced at high concentrations in areas of tissue damage and inflammation, but are rapidly metabolized by the sEH enzyme into inactive compounds. Effective inhibition of sEH activity prolongs the ability of EETs to exert their analgesic activity.

Study Groups

EC5026

Single 8 mg oral dose of EC5026

Group Type: EXPERIMENTAL

EC5026 oral tablet

Intervention Type: DRUG

12 subjects will receive a single oral 8 mg dose of EC5026 in two Dosing Periods (one in fed state and one in fasted state) separated by a Washout Period. Subjects in this group will be randomized 1:1 to one of 2 sequences:

• Dosing Sequence A: Subjects will be dosed in a fed state in Dosing Period 1 and in a fasted state in Dosing Period 2, or
• Dosing Sequence B: subjects will be dosed in a fasted state in Dosing Period 1 and in a fed state in Dosing Period 2.

Placebo

Single dose of matching oral placebo

Group Type: PLACEBO_COMPARATOR

Placebo oral tablet

Intervention Type: OTHER

6 subjects will receive an oral dose of matching placebo in one single Dosing Period. Subjects in this group will be randomized 1:1 to receive placebo under fed or fasted conditions.

Note: Subjects assigned to the placebo arm will not return for a second Dosing Period.

Eligibility Criteria

Inclusion Criteria

Each subject must meet all of the following criteria to be enrolled in this study:

1. Males or females must be 18-70 years of age.

2. Subjects must be willing to provide written informed consent to participate in the study.

3. Subjects must be in generally good health as determined by prestudy medical history, physical examination, clinical laboratory tests, and 12-lead electrocardiogram (ECG).

4. Subjects must be willing to remain in confinement at the CRU for up to 4 consecutive days in 2 separate dosing periods and to return to the unit as specified for additional blood tests and safety evaluations during the study period.

5. Subjects must have a body mass index of 19-32 kg/m2.

6. Subjects must have a normal blood pressure (systolic blood pressure 90-140 mm Hg, diastolic blood pressure 50-90 mm Hg) and heart rate (resting heart rate 45-90 beats per minute) without medication. Blood pressure and heart rate may be repeated at the discretion of the investigator. If the value continues to be out of range but not clinically significant, the subject may continue per the discretion of the investigator.

7. Subjects must have a clinical chemistry profile, including electrolytes, alkaline phosphatase (ALP), lactate dehydrogenase, creatine phosphokinase (CPK), creatinine, and urea, within the normal range without medication at screening. Subjects who have mildly out of range laboratory results that are not considered clinically significant by the investigator can be included in the study.

8. Subjects must have an early morning (collected between 0600 AM and 0800 AM) serum cortisol level >10 mcg/dL (>275.9 nmol/L) and early morning adrenocorticotropic hormone (ACTH) and aldosterone levels within the normal range at screening.

9. Subjects must be nonsmokers or willing to abstain from smoking 2 weeks prior to randomization and for the duration of the study.

10. Subjects must be able to read, understand, and follow the study instructions.

11. Male subjects and their female sexual partners must agree to use double-barrier contraception during the study period and for 2 months after clinic discharge or to provide proof of postmenopausal state (minimum 1 year) or surgical sterility. Surgical sterility will be defined as proof of female sterilization (via tubal ligation, bilateral salpingo-oophorectomy or hysterectomy) or male sterilization (vasectomy, with laboratory proof of postvasectomy sterilization assessed at least 16 weeks postprocedure).

12. Male subjects must not donate sperm during the study and for 12 months after receiving the last dose of study drug.

13. Female subjects must be nonpregnant, nonlactating, and either postmenopausal for at least 1 year, or surgically sterile for at least 3 months, or they must agree to use double barrier contraception from 28 days and/or their last confirmed menstrual period prior to study enrollment (whichever is longer) until 2 months after clinic discharge. Double-barrier contraception may include, but is not limited to, nonhormonal intrauterine device with spermicide, female condom with spermicide, diaphragm with spermicide, cervical cap with spermicide; having a male sexual partner who agrees to use a male condom with spermicide; or having a sterile sexual partner. Females on hormonal contraceptives ( including hormonal intrauterine device or oral contraceptives) will be excluded from the study. For all females of childbearing potential, the pregnancy test result must be negative at screening and prestudy baseline (Day -1).

Exclusion Criteria

Subjects meeting any of the following criteria will be excluded from the study:

1. Subjects with any abnormalities in any of the following: liver function tests, CPK, or urinalysis results.
