A Study to Assess Human Pharmacokinetics of a Medical Food Containing Tri-betahydroxybutyrin

Completed · Not applicable

Conditions studied: Healthy Volunteer

In brief

The objective of this clinical trial is to obtain PK information following the acute intake of a medical food containing tri-betahydroxybutyrin (3BHB) in 18 healthy male subjects. Blood samples will be obtained for the PK analysis of beta-hydroxybutyrate and acetoacetate at t = 1 and 2 h ± 5 min, where t = 0 h is the start of study product consumption. Subjects will be administered a standard breakfast immediately following the t = 2 h blood draw. Subjects will consume the breakfast meal within 30 min and will be instructed to eat until comfortably full. Blood samples will be obtained via the indwelling venous catheter or venipuncture at t = 3, 4, 6, 8, and 12 h ± 5 min, where t = 0 h is the start of study product consumption, for the PK analysis of beta-hydroxybutyrate and acetoacetate. Subjects will be administered a standard snack (immediately following the t = 4 h blood draw), a standard lunch (immediately following the t = 6 h blood draw) and a standard dinner (at t = 10 h) Subjects will consume the meals/snack within 30 min and will be instructed to eat until comfortably full. Following the final blood draw of Visit 2 (day 0) at t = 12 h ± 5 min, the catheter will be removed, AEs will be assessed and a standard snack will be administered for consumption prior to discharge from the clinic. At Visit 3 (day 1), subjects will return to the clinic for clinic visit procedures (i.e., vital signs; review inclusion and exclusion criteria for relevant changes, and concomitant medication/supplement use review). AEs will be assessed and subjects will be queried about study instructions compliance. Blood samples will be obtained at t = 24 h ± 5 min (with backups) by venipuncture for the PK analysis of beta-hydroxybutyrate and acetoacetate, where t = 0 h is the time of study product consumption.

You may qualify if…

• 1. Subject is a generally healthy male at least 60 years of age.

• Subject has a score of 7 to 10 on the Vein Access Scale at Visit 1 (day -7).
• Subject has a BMI of 18.5 and 29.9 kg/m2, inclusive at Visit 1 (day -7).
• Subject is willing to remain on a stable dose of prescription medications within 30 d prior to Visit 1 (day -7) and throughout the study period.

• Subject is willing to maintain habitual diet, physical activity patterns, and body weight throughout the trial.
• Subject is willing and able to comfortably abstain from caffeine prior to (10-14 h, target 12 h) and throughout the duration of all clinic visits (up to 14 h on Visit 2; day 0). (This is not a threat to validity to cognitive function; only possible alertness.)
• Subject is a non-user of all tobacco, smoking products (including, but not limited to cigarettes, cigars, chewing tobacco, e-cigarettes), and nicotine products (e.g., nicotine gum and/or nicotine patches) within 6 months of Visit 1 (day -7) and has no plans to change status during the study period.
• Subject is willing and able to comply with the visit schedule.
• Subject has no health conditions that would prevent him from fulfilling the study requirements as judged by the Clinical Investigator on the basis of medical history, physical examination findings, and routine laboratory test results.
• Subject understands the study procedures and signs forms providing informed consent to participate in the study and authorizes the release of relevant protected health information to the Clinical Investigator.

You may not qualify if…

• Subject is female.
• Subject has a fasting glucose greater than 125 mg/dL at Visit 1 (day -7). No retest allowed.
• Subject has abnormal laboratory test results of clinical significance at Visit 1 (day -7) on the basis of age and gender specific reference values and/or at the discretion of the Clinical Investigator, who has MD qualifications. One re-test will be allowed on a separate day prior to Visit 2 (day 0), for subjects with abnormal laboratory test results.
• Subject has a known allergy or sensitivity to any of the ingredients in the study products and/or any ingredients of the meals provided.
• Subject has any signs or symptoms of an active infection of clinical relevance (e.g., urinary tract or respiratory) within 5 d prior to Visit 2 (day 0). If an infection occurs during the study period, test visits should be rescheduled until all signs and symptoms have resolved (at the discretion of the Clinical Investigator) and any treatment (e.g., antibiotic therapy) has been completed at least 5 d prior to testing.
