Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Approximately 12 adults subjects will be enrolled. Participants will be randomized to one of two directly observed dosing regimens with 2mg adenine 5+ (five stable-labeled nitrogens) as follows: 1 dose/week followed by 4 doses/week OR 3 doses/week followed by 7 doses/week. Each dose regimen will have a duration of approximately 12 weeks and will be separated by a 12-week washout period for a total study duration of approximately 36 weeks. Dried blood spots (DBS) and whole blood will be collect weekly. Urine will be collected less frequently, about every 2 weeks. The ratio of ATP 5+ to naturally occurring ATP 2+ is dried blood spots will be the primary outcome, as adenine is phosphorylated to ATP in red blood cells. Breakdown products will be measured in urine. Investigators will allow flexibility in terms of which days are used for dosing for the 1, 3, and 4 dose(s)/week regimens. This is scientifically justified as investigators expect a 20-30 day half-life of ATP 5+ in DBS.
