REPURPOSING DIABETES DRUGS FOR NEURODEGENERATIVE DISEASES: ANTI DIABETIC DRUG REPOSITION

Abstract

This study was aimed to find drug repurposing opportunity of anti diabetic drugs for treatment of neurodegenerative diseases using pharmacovigilance approach. We have retrieved the source data from United States FDA Adverse Event Reporting System for the last 15 years covering duration from 2004 to 2018. Medical dictionary for Regulatory Activities, version 19.1 was used to decode the relevant preferred terms for reported indications and side effects. We have targeted reposition of anti diabetic drugs for neurodegenerative disease. A primary target was set to identify anti diabetic drug, which has therapeutic or prophylactic effect for neurodegenerative disease. Molecular mechanism of drugs and phenotypic characteristic of reported side effects were compared with ‘very common’ side effects of approved drugs for treatment of ‘neurodegenerative disease’. Statistical analysis includes quantitative methods to calculate proportional reporting ratio for confirmed signal. Signals calculated with proportional reporting ratio value more than two, were only considered as positive result outcome. Through our systematic review of safety data, we have identified rosiglitazone, insulin (intranasal administration) and exenatide as convincing molecules for them reposition to treat neurodegenerative disease as novel therapeutic indication. Through this study, we have proposed to create a novel opportunity to find anti diabetic drug that fully convinced for treatment of neurodegenerative disease. In future, well designed, double blind randomized controlled trials with large samples are required to conclude the efficacy of proposed reposition for anti diabetic drugs.
