Abnormal screening serum electrolytes and/or liver function tests vii. Laboratory evidence of prediabetic state or diabetes mellitus: Hemoglobin A1c ≥ 5.7%, and/or Fasting plasma glucose ≥ 100 mg/dL viii. Abnormal fasting lipids at screening (either of the following) Triglycerides ≥ 150 mg/dL LDL-cholesterol ≥ 160 mg/dL ix. Positive qualitative human chorionic gonadotropin beta subunit (β-hCG) (i.e., pregnancy test) in women of childbearing potential COVID-19 precautions i. Unwillingness to comply with masking requirements per hospital policy ii. Active, documented COVID-19 at any time after screening through study completion Reproductive concerns i. Women of childbearing potential not using highly effective contraception, defined as: Surgical sterilization (e.g., bilateral tubal occlusion, bilateral oophorectomy and/or salpingectomy, hysterectomy) Combined oral contraceptive pills taken daily, including during the study Intrauterine device (levonorgestrel-eluting or copper) active at the time of the study Medroxyprogesterone acetate (Depo-Provera®) injection active at the time of the study Etonogestrel implants (e.g., Implanon®, etc.) active at the time of the study Norelgestromin/ethinyl estradiol transdermal system (e.g., Ortho-Evra®) active at the time of the study ii.

Known allergy/hypersensitivity to any component of the medicinal product formulations (including soy or cow dairy), other biologics, venipuncture materials, plastics, adhesive or silicone, or ongoing clinically important allergy/hypersensitivity as judged by the investigator. Dietary restrictions (e.g.., vegan, kosher, halal) on gelatin present in overencapsulation Concurrent enrollment in another clinical study of any investigational drug therapy or use of any biologicals within 6 months prior to screening or within 5 half-lives of an investigational agent or biologic, whichever is longer.
