This early-stage study tested a single dose of an experimental drug called BNC in 75 healthy volunteers aged 55 and older. The goal was to see if the drug is safe and how the body processes it, as a first step toward possibly treating Alzheimer's disease. Participants took either…

This study looked at whether giving growth hormone can improve how the immune system works in healthy men aged 25 to 50. Participants received either growth hormone or a placebo through a small pump under the skin. The goal was to see if the hormone could reverse age-related immu…
