Brief summary: This is an open label, single-center, 4-period, 6-sequence study in healthy subjects to compare the PK of GED 0301 after a single oral dose in the fed and fasted state, and after co administration with omeprazole, a proton pump inhibitor.

The study will consist of a screening phase, a baseline phase, four treatment periods, and a follow up phone call five days (± 1 day) after discharge.

Detailed description: Subjects will be consented and screened within 21 days of dosing. They will undergo routine screening procedures including physical examinations (PE), 12 lead electrocardiograms (ECGs), vital sign measurements, clinical laboratory safety tests (clinical chemistry, haematology, urinalysis), pregnancy tests for females, and serology/drug/alcohol screens.

Eligible subjects will return to the clinic site on Day -1 for baseline safety assessments. After an overnight fast of at least 10 hours, subjects will be assigned randomly to one of six treatment sequences which will determine fasting status and the order in which treatments will be administered.

Subjects in the fasted arm will receive either a single 160 mg tablet of GED 0301 or four 40 mg tablets of GED 0301, with approximately 240 mL of room temperature, non-carbonated water.

Subjects in the fed arm will be required to fast overnight for at least 10 hours. On the morning of dosing, these subjects will be served a high-fat meal. The meal should be entirely consumed within 20 minutes of being served. Dosing of a single160 mg tablet of GED 0301 will occur within 30 minutes (± 5 minutes) after the start of the meal.

During the fourth period, subjects will receive once daily oral doses of 40 mg omeprazole for 6 days (Days 10 through 16). Subjects will fast on the evening of the fourth day for at least 10 hours prior to receiving the last treatment, which is a single dose of 160 mg GED 0301 together with one 40 mg oral dose of omeprazole (Day 15). On Day 16, subjects will take the last dose of omeprazole.

Serial blood sampling for the determination of GED 0301 levels in plasma will be performed during each period for 48 hours post dose.

Subjects will be domiciled at the clinic site from Day 1 of Period 1 until Day 17. All subjects will be discharged from the clinic site on Day 17 when all required safety and PK procedures have been completed.

A follow up phone call will occur five days (± 1 day) after discharge from the clinic center.

The study will be conducted in compliance with Good Clinical Practice (GCP), as described in International Conference on Harmonisation (ICH) Guideline E6 and in accordance with the general ethical principles outlined in the Declaration of Helsinki. The study will receive approval from an EC prior to commencement. The Investigator will conduct all aspects of this study in accordance with applicable national, state, and local laws of the pertinent regulatory authorities.

Eligibility criteria: Inclusion Criteria:

Subjects must satisfy the following criteria to be enrolled in the study:

1. Subject is male, or non-pregnant and non-nursing female ≥ 18 and ≤ 65 years of age the time of signing the ICF.
2. Subject must understand and voluntarily sign an ICF prior to any study related assessments/procedures being conducted.
3. Subject is willing and able to adhere to the study visit schedule and other protocol requirements.
4. Satisfactory medical assessment with no clinically significant or relevant abnormalities as determined by medical history, physical examination, vital signs, 12-lead ECG, and clinical laboratory evaluation (haematology, biochemistry, coagulation, and urinalysis) that is reasonably likely to interfere with the subject's participation in or ability to complete the study as assessed by the Investigator.
5. Female subjects NOT of childbearing potential must:

   1. Have been surgically sterilized (hysterectomy or bilateral oophorectomy; proper documentation required) at least 6 months before screening, or be postmenopausal (defined as 24 consecutive months without menses before screening, with a follicle stimulating hormone \[FSH\] level of \> 40 IU/L at screening).
6. Females of childbearing potential (FCBP) must have a negative pregnancy test at the Screening and Baseline Visits. While receiving investigational product (IP) and for at least 28 days after taking the last dose of IP, FCBP who engage in activity in which conception is possible must use one of the approved contraceptive options described below:

   Option 1: Any one of the following highly effective methods: hormonal contraception (oral, injection, implant, transdermal patch, vaginal ring); intrauterine device (IUD); tubal ligation; or partner's vasectomy.

   OR Option 2: Male or female condom PLUS 1 additional barrier method: (a) diaphragm with spermicide; (b) cervical cap with spermicide; or (c) contraceptive sponge with spermicide.
7. Male subjects must:

   a. Practice true abstinence (which must be reviewed on a monthly basis and source documented) or agree to use a barrier method of birth control (condoms not made out of natural \[animal\] membrane \[latex condoms are recommended\]) during sexual contact with a pregnant female or FCBP while participating in the study, during dose interruptions, and for at least 28 days after the last dose of IP, even if he has undergone a successful vasectomy.
8. Subject has body mass index (BMI) ≥ 18 and ≤ 33 kg/m2 at screening.
9. Subject has clinical laboratory safety test results that are within normal limits or acceptable to the Investigator.
10. Subject vitals are as follows:

    1. Tympanic body temperature: 35.0 - 37.5°C.
    2. Supine blood pressure (BP) after at least 5 minutes supine rest:

    i. Systolic BP: 90 - 140 mmHg ii. Diastolic BP: 40 - 90 mmHg c. Supine heart rate (after at least 5 minutes of rest): 40 - 90 beats per minute d. Postural drop (standing BP taken after no more than 1 minute standing) of ≤20 mmHG (systolic) or ≤10 mmHg (diastolic) associated with clinically relevant symptoms.
11. Subject has a normal or clinically acceptable 12 lead ECG at screening. In addition:

    1. If male, subject has a QTcF value ≤ 430 msec at screening.
    2. If female, subject has a QTcF value ≤ 450 msec at screening.

Exclusion Criteria:
