Eligibility Criteria

Age18 Years - 60 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Healthy male and female subjects between 18 and 60 years of age
  • Subjects with body weights greater than or equal to 50 kg and a body mass index (BMI) between 18 kg/m2 and 32 kg/m2
  • Female subjects of childbearing potential and males and their female partner(s) of childbearing potential must agree to use 2 forms of contraception, 1 of which must be a barrier method, during the study and for 30 days after the end of the study

You may not qualify if:

  • Pregnant or lactating females or male partners of females who are pregnant or lactating.
  • Subjects with any history of clinically significant bronchopulmonary, cardiovascular, cerebrovascular, hematologic, renal, hepatic, neurological, psychiatric, metabolic, or endocrine (eg, diabetes or thyroid disease) disease/disorder.
  • Use of prescription or over-the-counter (OTC) drugs, including vitamins and herbal or dietary supplements within 2 weeks (4 weeks for enzyme inducers including St. John's Wort) or 5 half-lives (whichever is longer), prior to the baseline/check-in visit, unless in the opinion of the investigator, prior use of the medication will not interfere with the study procedures or compromise subject safety.
  • Subjects with sustained supine or semi-supine systolic blood pressure of \< 90 or \> 140 mm Hg and supine or semi-supine diastolic blood pressure of \< 50 or \> 90 mm Hg at the screening or baseline/check-in visits.
  • Subjects with a resting heart rate of \< 45 or \> 100 beats per minute at the screening or baseline/check in visits.
  • Subjects with any clinically relevant deviation from normal during the physical examination, including vital signs at the screening or baseline/check-in visits.
  • Subjects with a known history of hypercalcemia, hyperparathyroidism, or hypervitaminosis D.
  • Use of calcium or vitamin D supplements (prescription or OTC) within 2 weeks prior to the baseline/check-in visit.
  • Subjects with a history of allergic reactions or hypersensitivities to galacto-oligosaccharides or any significant drug-related or food-related allergy (such as anaphylaxis or hepatotoxicity).
  • Regular use of probiotics, antacids, histamine type 2 (H2)-receptor blockers, proton pump inhibitors, or any medications that may alter the normal gastric environment and/or motility, or use of such medications within 2 weeks prior to the baseline/check-in visit.
