The Efficacy and Safety of an Amino Acid Supplement in Adults

Phase 2

Completed

• Conditions: Insulin-Like Growth Factor I; Healthy
• Interventions: Other: Placebo; Drug: Amino Acid Supplement

• Registration Number: NCT05599282
• Lead Sponsor: ZandA Technologies, llc

Brief Summary

The primary objective of this clinical trial is to determine the efficacy of once daily oral AAS use, as compared to placebo, in increasing serum IGF-1 concentrations within adults aged 35-75 years for up to 90 days. Additionally, the safety and tolerability of the AAS, as compared to placebo, will be measured by the occurrence of and/or changes in treatment-emergent adverse events (AEs).

For the study population, the eligibility criteria limit the presence of confounding variables that could influence study outcomes. Participants will be men and women between 35 and 75 years of age to account for the age range in which humans experience a decline in HGH/IGF-1. Each participant will be deemed eligible to participate by the Qualified Investigator (QI) by means of an extensive review of medical history, laboratory results, and physical examination. Participants will be required to have body mass index (BMI) measurements between 18.5 and 35.0 kg/m2 to ensure that their body weight/composition will not have a confounding effect on their HGH levels (18, 19) and to facilitate generalizability. Participants will be required to maintain current medication and supplements use and sleep throughout the study. They must also abstain from any over-the counter (OTC) medications and/or supplements that may affect the efficacy or safety of the AAS.

Arm && Interventions

Group	Intervention	Description
Placebo	Placebo	Participants will be instructed to take four (4) capsules of Placebo with a full glass of water daily for up to 90 days, starting on day 1. No substance other than water (i.e., food, drink other than water, and/or medication, supplement, vitamin, and/or mineral) can be consumed two hours before or after taking the placebo. The placebo must be consistently consumed immediately before nighttime sleep throughout the study. If a dose is missed participants are instructed to record the missed dose in their study journal. Missed doses will not be taken at a later time or date. If any substance other than water is consumed two hours before or after taking the placebo, that placebo use will be counted as a missed dose. Participants will be advised not to exceed four (4) capsules daily.
