Brief Summary

This study is designed to evaluate treatment effects of ATH-1017 (fosgonimeton) in mild to moderate Alzheimer's subjects with a randomized treatment duration of 26-weeks.

Detailed Description

This study is designed to assess the correlation of the functional translational biomarker P300 latency and change in ADAS-Cog11 induced by ATH-1017 therapy, over 26-week randomized, double-blind trea...

  • Hepatic impairment with alanine aminotransferase or aspartate aminotransferase \> 2 times the upper limit of normal, or Child-Pugh class B and C
  • Malignant tumor within 3 years before Screening
  • Memantine in any form, combination or dosage within 4 weeks prior to Screening
  • Donepezil at 23 mg PO
