bms-708163 and Syncope

To assess the efficacy and safety of Aβ-targeting agents for mild to moderate Alzheimer's disease.. The MEDLINE, Embase, Cochrane Central Register of Controlled Trials, PsycINFO, ClinicalTrials.gov and the WHO's International Clinical Trials Registry Platform search portal were searched from their inception to April 2020. We generated pooled estimates using random effects meta-analyses.. Nineteen randomised controlled trials, of which 17 had a low risk of bias, included 12 903 participants. The meta-analysis showed no difference in the cognitive subscale of Alzheimer's Disease Assessment Scale (ADAS-Cog) between anti-Aβ drugs and placebo (mean difference (MD): 0.20, 95% CI -0.40 to 0.81;. From current evidence, anti-Aβ interventions are unlikely to have an important impact on slowing cognitive or functional decline. Although the subgroup analysis suggested possible benefits from Aβ clearance drugs, the analysis has limited credibility, and a benefit from drugs that increase clearance, if real, is very small.. PROSPERO registration number CRD42019126272.
