About this study

Official title: A Phase 1/2a, Randomized, Placebo-Controlled, Double-Blind, Parallel-Group, Study of Safety, Tolerability, Pharmacokinetics and Activity of 14 Days of Oral Dosing With the 2S,4R Enantiomer of Ketoconazole (DIO-902) in Subjects With Type 2 Diabetes Mellitus

The study is designed to test the safety, tolerability of a newly developed form of ketoconazole (DIO-902) for the treatment of elevated blood sugars in type 2 diabetes. This study also will also examine the effect of the drug on total and LDL cholesterol and blood pressure. Elevated cortisol may contribute to the development of Type II diabetes. The investigational drug DIO-902 may reduce the level of cortisol in blood and therefore provide better control of blood sugar levels in patients with Type II diabetes.

Read the detailed description

DiObex is developing a modified form of ketoconazole (enantiomer) (DIO-902) as an investigational new drug for the treatment of the elevated blood sugar associated with type 2 diabetes. Other benefits may include reduced total and LDL cholesterol, and reduced blood pressure. With chronic treatment, reduced visceral fat may also be seen. Ketoconazole (racemic) is an approved drug for the treatment of a variety of fungal infections. The approved racemic ketoconazole inhibits cortisol synthesis. In patients with Cushings Disease racemic ketoconazole reduces glucose, cholesterol and blood pressure. Elevated cortisol may be a contributing causal factor in the development of type 2 diabetes; clinical trials with racemic ketoconazole have been carried out in these patients. The results of these clinical trials support the concept of treating type 2 diabetes through a lowering of plasma cortisol and provide evidence of the safety and tolerability of racemic ketoconazole. Racemic ketoconazole has, however, been associated with liver toxicity which is generally mild in nature. However, in rare cases (1:10,000 to 15,000 patients) severe liver toxicity may occur, and in extremely rare cases this adverse event may be irreversible and life-threatening. Preclinical results suggest that DIO-902 may be both safer and more efficacious than the racemic mixture.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing 2S, 4R Ketoconazole (DIO-902) in people with Type 2 Diabetes, run by DiObex at 5 sites 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 12 inclusion and 14 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 22 Feb 2008. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

To evaluate the safety and tolerability of 14 daily doses; To determine the pharmacokinetic (PK) profile in plasma of DIO-902 after a single dose, and after fourteen daily doses; To evaluate the pharmacodynamic effects of fourteen daily doses. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 22 Feb 2008.
