Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
β-amyloid accumulation outside brain cells and abnormal accumulations of tau protein inside neurons are taught to be two main changes in the brain that lead to AD. Progressive accumulation of β-amyloid interferes with the neuron-to-neuron communication at synapses, contributing to neural cell death. Also, tau tangles block the transport of nutrients and other essential molecules into the neurons. Many molecules have been shown to inhibit amyloid aggregation. The anti-amyloidogenic activity of trehalose was confirmed in both in vitro and in vivo studies and its inhibitory effects on β-amyloid formation in AD have also been demonstrated. Trehalose is a non-toxic disaccharide and no dose-dependent adverse effects were seen in any of the safety studies. It can act as a chemical chaperone and stabilizes the natively folded structure of protein and also trehalose has been identified as an autophagy inducer and promotes the clearance of aggregated proteins. Therefore, trehalose could be a valuable candidate for the treatment and prevention of amyloid-related disease. Based on the proposed hypothesis, this study aim to investigate the potential efficacy of trehalose administration in patients with AD.

Study Groups

Trehalose
Trehalose Participants will be received intravenous trehalose infusion weekly (15 g/week) for a period of 12 weeks.
Trehalose
Trehalose is a natural disaccharide sugar found extensively among miscellaneous organisms including bacteria, plants, insects, yeast, fungi, and invertebrates. By preventing protein denaturation, it plays various protective roles against stress conditions such as heat, freeze, oxidation, desiccation and dehydration. Owing to this capacity, trehalose is an FDA-approved pharmaceutical excipient that is used as a stabilizer in numerous medicines including parenteral products. In this study, all injections will be conducted by a trained nurse in the presence of a specialist physician at a duration of 45-90 minutes.
Placebo
Participants will be received equal volume of normal saline weekly for a period of 12 weeks.
