INTRODUCTION: Posatirelin (L-pyro-2-aminoadipyl-L-leucil-L-prolinamide) a new synthetic tripeptide with cholinergic, catecholaminergic and neurotrophic properties, was investigated in the treatment of Alzheimer's disease.
MATERIAL AND METHODS: A multicentre, double-blind study vs citicoline (reference drug) and ascorbic acid (inactive drug) was carried out in elderly patients suffering from late-onset Alzheimer's disease. The once daily intramuscular treatment lasted for three months followed by one-month oral treatment with a placebo. Subscales and factors of GBS (Gottfries-Bråne-Steen) Rating Scale were identified as primary measures for efficacy assessment.
RESULTS: At the end of the treatment, GBS subscale and factor scores assessing intellectual and emotional impairments, orientation and memory, ability to perform activities of daily living, depression-anxiety, attention and motivation were improved in the postatirelin group, showing significant differences with respect to the citicoline and/or ascorbic acid groups. Tolerability was good in all groups.
CONCLUSIONS: The improvement in the GBS Rating Scale score observed in the posatirelin group is clinically relevant. It is worth verifying the drug-induced functional improvements, in further studies with large samples.
