About this study

Official title: A Phase 2, Double-Blind, Randomized, Placebo-Controlled, Dose-Ranging, Study to Evaluate the Efficacy and Safety of 3 Doses of TAK-583 in Subjects With Mild to Moderate Diabetic Peripheral Neuropathy

The purpose of this study is to determine the safety and effectiveness of TAK-583, once daily (QD), in the treatment of neuropathy caused by diabetes mellitus.

Read the detailed description

Diabetic polyneuropathy is a frequent complication in individuals with type 1 and 2 diabetes mellitus, and can result in progressive functional and structural deficits in both somatic and autonomic nerves. Diabetic polyneuropathy is characterized by degenerative changes in nerve fibers resulting in progressive functional and structural deficits in both somatic and autonomic nerves.

TAK-583 is a synthetic compound currently under development for the treatment of diabetic polyneuropathy. The purpose of this study is to evaluate the safety and efficacy of TAK-583 for the treatment of mild to moderate diabetic polyneuropathy in subjects with type 1 or type 2 diabetes mellitus. Study participation is anticipated to be about 8 months.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing TAK-583 in people with Diabetic Neuropathies, run by Takeda at 38 sites in 2 countries.

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 16 inclusion and 31 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 Jun 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 38 sites in United States, Canada. 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 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?

Change from Baseline for a composite measure of Maximal Nerve Conduction Velocity of the Peroneal and Median Motor Nerves and the Median and Sural Sensory Nerves. (time frame: Month 6 or Final Visit). 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 Jun 2016; AzTrials last refreshed its copy on 8 Nov 2026.
