Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Proof-of-concept study on the effects of 10 mg fampridine (oral administration) on working memory in healthy participants.

The hypotheses is that fampridine improves working memory performance.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Fampridine SR

Single oral administration of a tablet fampridine (10 mg) formulated for oral administration taken once in the morning without food. Tablets must be administered whole.

The single intake is followed by a washout period of at least 7 days equalling over 40 half-lives of the active substance fampridine (t½ = 3.61 h) between experimental and control intervention.

Group Type EXPERIMENTAL

Fampridine SR

Intervention Type DRUG

Fampridine is an inhibitor of voltage-gated potassium (Kv) channels and is approved in Switzerland for treatment of gait problems in patients with Multiple Sclerosis (MS).

Placebo

Identically looking placebo tablets consisting of the identical additives formulated for oral administration.
