EVALUATION OF THE FEASIBILITY, SAFETY AND EFFICACY OF THE USE OF INTRAVENOUS INFUSIONS OF ADENOSINE TRIPHOSPHATE (ATP) IN PEOPLE AFFECTED BY MODERATE TO SEVERE ALZHEIMER\'S DISEASE: A DOUBLE-BLIND MASKED CLINICAL TRIAL FOR DOSE FINDING

Background: There are currently no drug therapies modifying the natural history of patients suffering Alzheimer’s disease (AD). Most recent clinical trials in the field include only subjects in early stage of the disease, while patients with advanced AD are usually not represented. Objectives: To evaluate the feasibility, safety and efficacy of systemic infusions of adenosine triphosphate (ATP) in patients with moderate to severe AD, and to select the minimum effective dose of infusion. Design: A phase IIb, randomized, double-blind, placebo-controlled clinical trial investigates. Participants: A total of 20 subjects with moderate or severe AD were included, 16 in the treatment group and 4 in the placebo group (4:1 randomization) at two dosage regimens, 6-hour or 24-hour infusions. Results: The proof-of-concept study was successfully conducted, with no significant deviations from the study protocol and no serious adverse events reported. Regarding efficacy, only marginal differences were observed between ATP and placebo arms for H-MRS and MMSE variables. Conclusions: Our study demonstrates that the use of ATP infusion as therapy is feasible and safe. Larger studies are however needed to assess the efficacy of ATP in moderate to severe AD.
