Accepts healthy volunteers: yes
Allocation: RANDOMIZED
Intervention model: CROSSOVER
Intervention model description: In each period, participants will receive Treatment A or Treatment B according to the randomization scheme:

* Treatment A: No food will be allowed from at least 10 hours before dosing until at least 4 hours after dosing.
* Treatment B: After a supervised overnight fast of at least 10 hours, participants will be served a high-calorie and high-fat breakfast, in compliance with the FDA Guidance for Industry: Assessing the Effects of Food on Drugs in INDs and NDAs - Clinical Pharmacology Considerations (2022). Breakfast will be served approximately 30 minutes prior to CRS3123 administration. Participants will fast for no less than 4 hours after study drug administration.
Primary purpose: BASIC_SCIENCE

Brief summary: This study will explore the potential effects of high-fat meal on the plasma pharmacokinetics (PK) of CRS3123 when administered as a single oral dose of 200 mg in healthy adult participants.

Detailed description: This study will assess the impact of a high-calorie and high-fat meal on the plasma pharmacokinetics (PK) of CRS3123 in healthy adult participants when administered as a single oral capsule of 200 mg dose. Pharmacokinetics (PK) of a single dose of CRS3123 200 mg will be studied following administration to healthy participants under fed and fasted conditions.

   2. the absence of clinically significant history of neurological, endocrine, cardiovascular, respiratory, hematological, immunological, psychiatric, gastrointestinal (GI), renal, hepatic, and metabolic disease.
3. Healthy females (as assigned at birth) of non-childbearing potential must be:

   1. postmenopausal (spontaneous amenorrhea for at least 12 months prior to dosing) with confirmation by documented follicle stimulating hormone (FSH) levels greater than or equal to 40 mIU/mL; or
   2. surgically sterile (bilateral oophorectomy, hysteroscopic tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion, bilateral salpingectomy, hysterectomy or tubal ligation) at least 3 months prior to dosing.
4. Sexually active females (as assigned at birth) of childbearing potential and non-sterile males (as assigned at birth) must be willing to use an acceptable contraceptive method throughout the study.
5. Able to understand the study procedures and provide signed informed consent to participate in the study.

Exclusion Criteria:

1. Any clinically significant abnormal finding at physical examination at screening that may interfere with the interpretation of safety and PK objectives of the study.
2. Abnormal laboratory test results (above Grade 1) that may interfere with the interpretation of safety and PK objectives of the study.
3. Positive serology test results for hepatitis B surface antigen (HBsAg), hepatitis C virus (HCV) antibody or human immunodeficiency virus (HIV) antigen and antibody.
4. History of current or chronic liver disease or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
5. Positive pregnancy test at screening or admission to the clinical research unit.
6. Positive urine drug screen, urine cotinine test, or alcohol test at screening or admission to the clinical research unit.
7. Known allergic reactions to CRS3123 or other related drugs, or to any excipient in the formulation.
8. Use of medications within specified timeframes.
9. Previous exposure to CRS3123 within 12 months prior to the first dose.
10. Participants with HR \< 50 or \> 100 beats per minute (bpm), systolic blood pressure (SBP) \< 90 or \> 140 mmHg, diastolic blood pressure (DBP) \< 50 or \> 90 mmHg, on vital sign assessment at screening or admission to the clinical research unit.
11. A baseline ECG at screening with corrected QT interval (QTc) using Fridericia's formula (QTcF) \> 450 msec.
12. Evidence of previous myocardial infarction (does not include ST segment changes associated with repolarization). Any clinically significant (above Grade 1) conduction abnormality (including but not specific to left or right complete bundle branch block, atrioventricular block \[second degree or higher\], Wolf Parkinson White syndrome), sinus pauses \> 3 seconds, non sustained or sustained ventricular tachycardia (≥ 3 consecutive ventricular ectopic beats) or any significant arrhythmia which, in the opinion of the Investigator will interfere with the safety of the individual participant.
13. Participant has any surgical or medical condition (active or chronic) or GI tract condition (e.g., surgical resection of significant proportions of the stomach or bowel, gastric bypass, gastric banding, irritable bowel syndrome, inflammatory bowel disease, or any other condition that may interfere with normal gastric emptying or transit time) that may interfere with drug absorption, distribution, metabolism, or excretion of the study drug, or any other condition that may place the participant at risk, in the opinion of the Investigator.
14. Participation in a clinical research study involving the administration of an investigational or marketed drug or device within 30 days or 5× t½ (whichever is longer) prior to the first dose, administration of a biological product in the context of a clinical research study within 90 days or 5× t½ (whichever is longer) prior to the first dose or concomitant participation in an investigational study involving no drug or device administration.
