A Phase 1 study testing EGT0001474 in people with Diabetes Mellitus Type 2, run by Theracos at 1 site in United States.
Trial summary
The purpose of this study is to determine the safety, tolerability and pharmacokinetics (how much of the drug gets into the blood and how long it takes the body to get rid of it) of single doses of EGT0001474 given to patients with Type 2 diabetes. Read more about this study

About this study
Official title: A Phase I, Randomized, Placebo-Controlled Study to Assess the Safety, Tolerability and Pharmacokinetics of EGT0001474 in Subjects With Type 2 Diabetes
The purpose of this study is to determine the safety, tolerability and pharmacokinetics (how much of the drug gets into the blood and how long it takes the body to get rid of it) of single doses of EGT0001474 given to patients with Type 2 diabetes. The study will also evaluate how EGT0001474 affects the amount of glucose produced by the body in the urine.
Read the detailed description
EGT0001474 is a compound that may inhibit the effect of other compounds in the body known as sugar transporters. The use of EGT0001474 may enhance the elimination of glucose from the blood by increasing the amount of urine produced. This would help prevent an abnormal decrease in blood sugar (hypoglycemia) both during fasting and after meals without increasing insulin secretion (which may result in weight gain or an abnormal increase in blood sugar known as Type 2 diabetes).

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing EGT0001474 in people with Diabetes Mellitus Type 2, run by Theracos at 1 site in United States.
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 7 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: finished, as of the sponsor's last update on 17 Jun 2019. 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 United States. 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?
Yes. Results are posted in the registry (first posted 17 Aug 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Safety and Tolerability of EGT0001474 (time frame: 25 days). The study lists 10 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 NCT00924053, which also lists 14 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 17 Jun 2019.
