Objectives: Souvenaid®, containing the specific nutrient combination Fortasyn™ Connect1, is designed to support synapse formation and function in patients with Alzheimer's disease (AD). Two randomised controlled trials (RCTs) have shown that Souvenaid improves memory performance in drug-naïve mild AD patients (MMSE 20-26 and MMSE≥20), indicating that Souvenaid may have positive effects in (very) early AD as well. The 'LipiDiDiet' study2 is one of the first RCTs in prodromal AD, investigating the effects of Souvenaid on cognition.
Methods: The LipiDiDiet study is a 24-month, double-blind, parallel-group RCT investigating the effects of Souvenaid in 300 prodromal AD patients (criteria Dubois, 2007). Primary outcome measure is cognitive functioning as assessed by a Neuropsychological Test Battery. Baseline characteristics of the study population are analysed.
Results: So far, randomised patients with available data (n=213, 47.9% male) had a mean age of 71.8±6.9 y, MMSE total score 26.6±2.0, ADAS-cog score 19.7±7.8, CSF β-amyloid 1-42/1-40x10 ratio 1.89±0.71, CSF total tau 465.5±269.6 pg/ml, CSF phosphorylated tau 74.5±35.6 pg/ml and MTA score 1.64±1.00 (MRI evidence for medial temporal lobe atrophy).
Conclusions: Baseline characteristics of the study population included in the LipiDiDiet study so far conform to the criteria for the target population of prodromal AD, with evidence for underlying AD pathology. Characteristics of the total study population will be presented at the conference. First results of the study are expected in 2015.
