Allopregnanolone Regenerative Therapeutic for MCI/AD: Dose Finding Phase 1

Description

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.

Phase

Phase 1 - a new treatment that has not been tested, and researchers are looking for the best way to administer the treatment and how much can be given safely. Phase I trials are usually offered only to patients with advanced disease who would not be helped by other known treatments. Some patients are helped by these treatments, although in this early stage physicians don’t really know if the treatment will be effective.
