Pregabalin in the Treatment of Pain Due to Diabetic Peripheral Neuropathy
A Phase 4 study testing Pregabalin in people with Diabetic Neuropathy, Painful, run by Pfizer's Upjohn has merged with Mylan to form Viatris Inc. at 30 sites in United States.
Trial summary
The purposes of this study are to: 1) find out if pregabalin relieves pain in subjects with painful diabetic peripheral neuropathy; 2) find out if pregabalin is safe at a dose of 600 mg/day (taken twice a day); and 3) find out if changes in nerve function happen during the study.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Pregabalin in people with Diabetic Neuropathy, Painful, run by Pfizer's Upjohn has merged with Mylan to form Viatris Inc. at 30 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 2 inclusion and 1 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 25 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 30 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 phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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?
Nerve conduction measurements; Pain scores from patient diaries. 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 NCT00159679, which also lists 6 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 25 Jan 2021.
