4. Total fasting (minimum of 10 hours) TGs ≥400 milligrams per deciliter (mg/dL) (4.5 millimoles per liter (mmol/L)) at Screening (Visit S1);
5. Fasting glucose \>126 mg/dL at Screening (Visit S1);
6. Uncontrolled hypothyroidism, including thyroid stimulating hormone (TSH) \>1.5 × the upper limit of normal (ULN) at Screening (Visit S1); patients stabilized on thyroid replacement therapy for at least 6 weeks prior to randomization (Visit T1/Day 1) are allowed; Liver disease or dysfunction, including positive serology or hepatitis B and/or C or significant elevations in certain liver function tests
7. Renal dysfunction or glomerulonephritis, including estimated glomerular filtration rate (eGFR; using the Chronic Kidney Disease Epidemiology Collaboration \[CKD-EPI\] 2021 formula) \<60 milliliters per minute (mL/min) at Screening (Visit S1).
8. Gastrointestinal conditions or procedures (including weight loss surgery; e.g., Lap-Band® or gastric bypass) except uncomplicated cholecystectomy and appendectomy that may affect drug absorption;
9. Known history of hematologic or coagulation disorders or a hemoglobin level \<10.0 grams/deciliter (g/dL) at Screening (Visit S1);
10. Active malignancy, including those requiring surgery, chemotherapy, and/or radiation in the past 5 years. Nonmetastatic basal or squamous cell carcinoma of the skin and cervical carcinoma in situ are allowed;
11. Unexplained creatine kinase (CK) \>3 × ULN at any time prior to randomization (i.e., not associated with recent trauma or physically strenuous activity). Patients with an explained CK elevation must have single repeat CK ≤3 × ULN prior to randomization;
12. History of drug or alcohol abuse within the last 2 years or reported current consumption of \>14 alcoholic drinks/week, or any illicit drug use (checked positive for standard drug screening panel). Patients testing positive for tetrahydrocannabinol (THC) (whether prescribed or not) and for amphetamine derivatives prescribed by and under the care of a health care practitioner (except for weight management) can be enrolled after evaluation and at the discretion of the investigator;
13. Inability to follow the required minimum 2 meals a day, or unwillingness to consume meal on both study test occasions, or inability to fast, as required during the study;
14. Blood donation, participation in multiple blood draws, clinical study, major trauma, blood transfusion or surgery with or without blood loss within 30 days prior to randomization (Visit T1/Day 1);
15. Use of any experimental or investigational drugs except GLP-1 agonists within 30 days or 5 half-lives (whichever is longer) prior to Screening (Visit S1);
16. Use of any prohibited diabetes or other weight loss drugs prior to or during the study (as specified) unless meeting specific rescue criteria:
17. Recent (within 30 days unless otherwise specified) initiation or discontinuation of lipid-lowering medications. Consistent background use is allowed;
18. An employee or contractor of the facility conducting the study, or a family member of the principal investigator, co-investigator, or any Sponsor personnel;
19. Pregnant, breastfeeding, or intending to become pregnant within 30 days after study completion or last dose of study drug;
20. A medical or situational (i.e., geographical) finding that, in the investigator's opinion, may compromise the patient's safety or ability to complete the study.
