Official title

Phase II Multicenter 16-Week Randomized Double Blind Placebo-Controlled Evaluation of the Efficacy, Tolerability and Safety of Memantine Hydrochloride on Enhancing the Cognitive Abilities of Adolescents and Young Adults With Down Syndrome

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this research study is to learn if the medication Memantine Hydrochloride (the study medication) can help adolescents and young adults with Down syndrome. Dr. Alberto Costa and his research team want to see if a 16-week treatment with this medication can improve the participant's ability to learn and remember things. In this study, memantine hydrochloride will be used. Thus, the researchers want to learn whether the study drug can help improve memory in young adults with Down syndrome. To test the effect of the study medicine, half of the people in the study will receive the study medicine and half will receive a placebo (an inactive substance). Memantine is an approved medication to treat memory and thinking problems in persons with Alzheimer disease. However, little is known about the effect of this medication in persons with Down syndrome and it has not been approved for use in persons with Down syndrome.
