To assess the effect of food on the pharmacokinetic profile of SSP-004184 compared to administration under fasted conditions.

Inclusion Criteria:

• Age 18-65 years inclusive at the time of consent. The date of signing informed consent is defined as the beginning of the Screening Period. This inclusion criterion will only be assessed at the Screening Visit.

• Subject is willing to comply with any applicable contraceptive requirements of the protocol and is:
• Male, or
• Female of non-childbearing potential (defined as a female who is post-menopausal [amenorrhea for at least 12 consecutive months] or surgically sterile [hysterectomy, bilateral tubal ligation, bilateral oophorectomy, or bilateral salpingectomy]) and at least 6 weeks post-sterilization

• Body mass index between 18.5-30.0kg/m² inclusive. This inclusion criterion will be assessed only at the Screening Visit.
• Ability to swallow the investigational product (multiple capsules at 1 time or consecutively 1 capsule at a time).

Exclusion Criteria:

• Confirmed systolic blood pressure >139mmHg or <89mmHg, and diastolic blood pressure >89mmHg or <49mmHg.
• Twelve-lead ECG demonstrating QTc >450msec at screening. If QTc exceeds 450msec, the ECG should be repeated 2 more times and the average of the 3 QTc values should be used to determine the subject's eligibility.
• Subject reports any food allergies, celiac disease, or requirements for specific diet (eg, vegan, vegetarian, low fat).
• Acute illness, as judged by the investigator, within 2 weeks of Day 1 of Treatment Period 1.

• History of alcohol or other substance abuse within the last year.
• Routine consumption of more than 3 units of caffeine per day or subjects who experience caffeine withdrawal headaches.
• A positive screen for alcohol or drugs of abuse at the Screening Visit.
• Male subjects who consume more than 3 units of alcohol per day. Female subjects who consume more than 2 units of alcohol per day.
• A positive human immunodeficiency virus antibody screen, hepatitis B surface antigen screen, or hepatitis C virus antibody screen.
• Current use of any other medication (including over-the-counter, herbal, or homeopathic preparations) that could affect (improve or worsen) the study evaluations according to the investigator.
• Use of tobacco in any form (eg, smoking or chewing) or other nicotine-containing products in any form (eg, gum, patch) within 30 days prior to Day 1 of Treatment Period 1.
• Donation of blood or blood products (eg, plasma or platelets) within 60 days prior to Day 1 of Treatment Period 1.
• Use of another investigational product within 30 days prior to Day 1 of Treatment Period 1 or active enrollment in another drug or vaccine clinical study.
• Substantial changes in eating habits within 30 days prior to Day 1 of Treatment Period 1, as assessed by the investigator.
• Prior screen failure, randomization, participation, or enrollment in this study.

The Safety Set consists of all subjects who have taken at least 1 dose of investigational product and have at least 1 post-dose safety assessment.
