Exclusion Criteria

• •Has acute, severe gastroenteritis and pronounced dehydration in the past 48 hours prior to Screening, chronic parenteral feeding or persistent severe vomiting.
• •Has known hypersensitivity to Spirulina, egg, milk products or wheat allergens.
• •Has a known disturbance of small intestinal absorption, exocrine pancreatic function, liver metabolism or pulmonary function.
• •Has a history of anorexia nervosa or bulimia.
• •Previous history of bezoars (the presence of retained liquid, bile, or small amounts of poorly organized food residue is permitted).
• •Prior surgery involving any gastrointestinal surgery, including the luminal gastrointestinal (GI) tract (cholecystectomy and appendectomy are permitted if performed \>3 months prior to baseline GEBT).
• •Any abdominal or pelvic surgery within the past 3 months.
• •Known history of the following GI conditions: inflammatory bowel disease; irritable bowel syndrome with diarrhea; or any other active disorder that could explain symptoms in the opinion of the investigator.
• •Has active diverticulitis, diverticular stricture, and other intestinal strictures.
• •Currently taking Glucagon-like peptide-1 (GLP-1) agonists, e.g. exenatide, liraglutide, semaglutide or dulaglutide, or pramlintide.
• •Has severe psychiatric illness (including suicidal tendencies or ideation) or neurological illness.
• •Use of narcotics/opioids, drugs used to treat gastroparesis within 3 days of the Screening GEBT test.
• •Clinically significant cardiac disease including but not limited to unstable angina, acute myocardial infarction within 6 months of baseline, and arrhythmia requiring therapy.
• •Patient has QTc interval ≥ 480 milliseconds on Screening ECG.
• •History of cerebral hemorrhage, cerebrovascular accident, transient ischemic attack, gastrointestinal bleeding, or retinal hemorrhage within 6 months of baseline.
• •Patient has active or history of neoplastic disease (except for adequately treated non-invasive basal cell and/or squamous cell carcinoma of the skin or carcinoma in situ of the cervix) within the past 5 years prior to baseline.
• •Presence of clinically significant medical condition(s) including but not limited to: renal, hepatic, cardiovascular, hematological, gastrointestinal, endocrine, pulmonary, neurological, psychiatric, substance abuse, and or any other clinically significant disease or disorder, which in the opinion of the investigator, may put the patient at risk due to participation in the study, influence the results of the study, and/or affect the patient's ability to complete the study.
• •History of or current diagnosis of active tuberculosis (TB); undergoing treatment for latent TB infection (LTBI); untreated LTBI (as determined by documented results within 3 months of the Screening Visit of a positive TB skin test with purified protein derivative with induration ≥ 5 mm, a positive QuantiFERON TB test or positive or borderline T-SPOT \[Elispot\] test); or positive TB test at Screening. Patients with documented completion of appropriate LTBI treatment would not be excluded and are not required to be tested.
• •Currently taking known P-gp and BCRP inhibitors or inducers and gastric acid reducing agents. E.g., proton pump inhibitors or H2 receptor antagonists.
