Summary

This phase 2 trial tests whether allopregnanolone, a natural hormone, can safely help repair the brain in people with early Alzheimer's disease. About 100 volunteers aged 55 to 80 will receive weekly infusions of the drug or a placebo for several months. Researchers will measure changes in brain volume and memory performance.

What this could lead to
