Allopregnanolone Regenerative Therapeutic for MCI/AD: Dose Finding Phase 1
The purpose of this study is to evaluate the safety and tolerability of allopregnanolone, a
naturally occurring brain steroid, in mild cognitive impairment and early Alzheimer's disease
participants. The primary goal is to determine the maximally tolerated dose.

participants. The primary goal is to determine the maximally tolerated dose.
1) Each dose group will be comprised of 8 participants (6 randomized to allopregnanolone; 2
randomized to placebo) administered one dose of allopregnanolone or placebo once per week for
12 weeks. A higher dose will be administered to the next group of participants when the lower
dose is shown to be safe and tolerable. 2) Pharmacokinetic analyses will be conducted on
blood samples taken from participants at the beginning and end of the trial. 3) The trial
will assess safety including via MRI brain imaging.
