Cross-over Study on the Influence of Fampridine on Working Memory in Mild to Moderate Depression

Cognitive deficits, including working memory deficits, are often present in depression and there are currently no effective pharmacological treatments targeting working memory deficits. Papassotiropoulos et al. (2024) has recently demonstrated that fampridine, a potassium channel blocker, can enhance working memory in healthy individuals with lower baseline performance, suggesting it may hold potential for addressing cognitive deficits in clinical populations. The primary aim of this study is to evaluate whether fampridine improves working memory performance in mild to moderate depression

Randomized placebo-controlled phase II cross-over study on the influence of fampridine on working memory in mild to moderate depression The primary objective of this study is to evaluate if fampridine improves working memory in mild to moderate depression. It will also be assessed whether baseline working memory performance or subjective working memory deficits moderate the drug's effect. The secondary objectives are to assess the influence of fampridine on different working memory functions, attention, cognitive flexibility, affective working memory and mood. Intervention:Twice daily oral administration of 10 mg fampridine (Fampyra®) for 7.5 days with a wash-out period of at least 6.5 days Control intervention:Twice daily oral administration of placebo for 7.5 days Study population:Total of 38 participants.
