A Study to Assess THN391 in Subjects With Alzheimer's Disease
Sponsor: Therini Bio, Inc.
Summary
This is a Phase 1b study to evaluate different doses of the drug and see whether a drug is safe and how it behaves in the body. THN391 has already been assessed in healthy people without Alzheimer's disease. This is the first study of THN391 in patients with Early Alzheimer's disease. Later studies will evaluate THN391 to see if it is effective for the treatment of Alzheimer's disease. In this study, THN391 will be compared with a placebo (a look-alike substance that contains no drug). The study duration is approximately 6 months in which the participants will visit the clinic approximately 13 times and have 2 telephone calls with the site. Patients who fulfill all criteria to participate in the study, will receive 3 times a monthly dose of THN391 or placebo in the clinic. Assessments that will be done at several timepoints during the study will be blood collection, physical examinations and neurological examinations, 4x an MRI-scan of the head, 2x a spinal tap and some testing of the memory and thinking skills.
Official title: A Double-blind, Randomized, Placebo-controlled, Phase 1b Study to Assess the Safety, Tolerability and Pharmacokinetics of Multiple Ascending Doses of THN391 in Early Alzheimer's Disease Subjects
