About this study
Official title: Evaluation of the Therapeutic Effects of Trehalose in Patients With Alzheimer Disease
Alzheimer's disease (AD) is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills, and, eventually, the ability to function independently. Despite the significant effort to understand the basic biology of the disease and pharmaceutical advances to develop drugs, there is no effective therapy available to treat AD or slow the disease progression.
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.
Read the detailed description
Purpose of the study: A randomized, triple-blind, pilot clinical trial has been designed to evaluate the effectiveness of trehalose on reducing the symptoms in AD patients. Study intervention: twenty patients with Alzheimer's disease were randomly divided into an intervention and a control group. Trehalose will be administrated intravenously (15 g/week) for 12 weeks in the intervention group and the control group will be received normal saline as a placebo.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
TrehaloseDrug
Also called Mycose
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.
| Study group | Role | What they receive |
|---|---|---|
| Trehalose | Experimental | Trehalose Participants will be received intravenous trehalose infusion weekly (15 g/week) for a period of 12 weeks. Receives: Drug: Trehalose |
| Placebo | Placebo comparator | Participants will be received equal volume of normal saline weekly for a period of 12 weeks. Receives: Drug: Trehalose |
What is being measured
The primary outcome is the main question the study is designed to answer.
Changes of Mini-Mental State Exam (MMSE)
Global cognition will be assessed by MMSE test, which will be conducted at baseline and week 12.
Measured: From baseline to 12 weeks
Changes in Clinical Dementia Rating Scale (CDR)
Clinical Dementia Rating Scale (CDR) has six different cognitive and behavioral domains such as memory, orientation, judgment and problem solving, community affairs, home and hobbies performance, and personal care, which will be conducted at baseline and week 12.
Measured: From baseline to 12 weeks

Clinical summary

Despite the significant effort to understand the basic biology of the disease and pharmaceutical advances to develop drugs, there is no effective therapy available to treat AD or slow the disease progression.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Trehalose in people with Alzheimer Disease, run by Mashhad University of Medical Sciences at 1 site in Iran.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 11 Dec 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Iran. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Amirhossien Sahebkar, PhD (+985138002299, SahebkarA@mums.ac.ir), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Changes of Mini-Mental State Exam (MMSE) (time frame: From baseline to 12 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04663854, which also lists 13 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Dec 2020.
