Inclusion criteria
Inclusion criteria: 1. Subject understands the study design and has been informed of the investigational nature of the study. Subject has given voluntary, written, informed consent to take part in this study. 2. Subject agrees to be compliant and is capable of completing the required study assessments. 3. Male or female age =21 to =75 years at time of signing informed consent. 4. All subjects (male or female) who are of childbearing potential must agree to use highly-effective, double contraception (with male/female partners) during the study. Double contraception is defined as use of a condom by the male partner, combined with use of 1 of the following forms of highly-effective contraception by the female partner: a. Oral contraceptive pills b. Depot or injectable contraceptive c. Intrauterine device (IUD) d. Contraceptive patch (e.g., Xulane®) or NuvaRing® e. Documented evidence of tubal ligation at least 6 months prior to the screening visit). Male subjects with a history of vasectomy should also use condoms as double contraception during the study. Use of highly-effective, double contraception must continue for 30 days or 5 half-lives (whichever is longer) after the last dose of IP. Female subjects must not donate oocytes during this time. Male subjects must not donate sperm during this time. Rhythm methods are not considered as highly-effective methods of birth control. Subject abstinence for the duration of the study and 30 days or 5 half-lives (whichever is longer) after last dose of IP is acceptable if it is the subject’s regular practice. 5. Females of childbearing potential must have a negative serum pregnancy test at screening V2 and agree to undergo a urine pregnancy test at V3/3.1, V4, V8 and V12, and a serum pregnancy test at end of the study (V13). 6. Females not of childbearing potential will be defined for this study as postmenopausal (defined as cessation of regular menstrual periods for at least 12 months) and confirmed by follicle-stimulating hormone (FSH) level OR surgically sterile (e.g., total hysterectomy, partial hysterectomy, or oophorectomy). 7. Serum TG criteria meeting all of the following criteria: a. A historical documented TG =400 mg/dL (4.52 mmol/L) in the past 5 years from screening V1, or currently on lipid-modifying therapy due to SHTG at screening V1. b. Mean of 2 screening fasting serum TGs = 500 mg/dL (5.65 mmol/L) and =2000 mg/dL (22.60 mmol/L). The target for the study is 500 mg/dL. Due to TG variability, up to 10% of subjects enrolled may have a mean qualifying TG level between 475 and 500 mg/dL. Mean screening fasting serum TG is defined as the mean of TG at V2 and V3, or V3 and V3.1 if the average of TG at V2 and V3 is 2000 mg/dL. The repeat measure of TG is permitted at a minimum of 7 days apart at V3.1. c. If 1 of the 2 qualifying TGs is <400 mg/dL, the difference between 2 TG should be <300 mg/dL. Note: If a subject has an individual fasting TG value of <350 mg/dL at any one visit or mean of two fasting TG levels <475 mg/dL, they will be considered a screen fail and not eligible to be re-screened. 8. Willing to maintain current eating and exercise habits from time of signing the informed consent and for the duration of the study. (See also Inclusion Criterion #11 and Exclusion Criterion #10 regarding alcohol consumption and Exclusion Criterion #4 regarding weight changes.). 9. Concomitant medication may include prescription fish oil (including purified eicosapentaenoic acid [EPA] with or witho
Exclusion criteria
Exclusion criteria: 1.Females who are pregnant or breastfeeding, or planning to become pregnant, or breastfeed while enrolled in the study or within 30 days or 5 half-lives (whichever is longer) after last dose of IP. 2.Uncontrolled or newly diagnosed (2 antihypertensive medications may be eligible with Medical Monitor (or designee) approval. 3.Body mass index (BMI) >45 kg/m2 at screening V1. 4.Weight change =5% in 3 months prior to screening V1 or weight change =5% between screening V1 and V3. 5.Central laboratory hemoglobin levels below the lower limit of normal (3× upper limit of normal (ULN) at screening V1. 8.Total bilirubin exceeds ULN at screening V1, unless prior diagnosis and documentation of Gilbert’s syndrome in which case total bilirubin must be =3 mg/dL. 9.Creatine kinase (CK) >5× ULN at screening V1. 10.Risky drinking (defined as alcohol intake >14 standard drink units per week or 4 standard drinks on a single occasion in men; and alcohol intake >7 standard drink units per week or 3 standard drinks on a single occasion in women) within the 24 months before screening V1 or had positive alcohol test at screening V3 or at V4. A unit of alcohol is defined as 14 gram or as 355 mL of beer (5% alcohol by volume [ABV]), 1 glass of wine (150 mL; 12% ABV), or 1 shot of hard liquor (45 mL; 40% ABV). During the study, subjects will receive counseling and will be encouraged to abstain from alcohol. Alcohol intake will be limited to 2 units of alcohol per day for men and 1 unit of alcohol per day for women. Subjects must be willing to abstain from alcohol use 48 hours prior to study visits. 11.Concomitant use of PCSK9 inhibitors, niacin, or any supplements, including non-prescription, non-pharmaceutical strength fish oils, used to alter lipid metabolism. Previous treatment with a PCSK9 inhibitor will need to have ceased >12 weeks before screening with no intention to reinitiate treatment for the duration of the trial. Other lipid-modifying supplements including, but not limited to, red rice yeast supplements, garlic supplements, soy isoflavone supplements, sterol/stanol products, or policosanols are not permitted. a.Subjects participating in the main cohort previously treated with a fibrate will need to agree to cease fibrate treatment for the duration of this trial. b.Subjects enrolled in the fibrate expansion cohort will need to maintain their current stable dose of fibrate therapy (=4 weeks before screening V1). 12.Previous long-term (>4 weeks) use of systemic steroid (glucocorticoid) medications such as prednisone within 12 months of screening V1. Inhaled or topical corticosteroids are permitted. 13.Reduced renal function (eGFR =55 mL/min/1.73 m2 calculated using chronic kidney disease epidemiology collabo
