About this study
Official title: Intra-articularInjection of Botulinum Toxin Type a for the Treatment of Chronic Knee Pain: A Randomized, Placebo Controlled, Double Blind Study
The purpose of this study is to determine whether intra-articular injection of botulinum toxin is effective in the treatment of chronic knee paindue to arthritis.
Read the detailed description
Chronic knee pain unresponsive to oral medications and intra-articular corticosteroids and viscosupplements is an important treatment problem, especially for the young, very old and those with complex medical problems that preclude joint reconstructive surgery. We hypothesized that intra-articular botulinum toxin could provide important joint pain relief in these patients. This is a prospective, double blined, placebo controlled 6month trial with an open label extension phase when pain returns to baseline levels (re-injection with 100units of botulinum toxin and 6 months followup thereafter.
Comparisons: Intra-articular injection of bootulinum toxin type a will be compared to intra-articular injection of lidocaine the saline.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Botulinum Toxin Type A in people with Arthritis and Pain, run by Minneapolis Veterans Affairs Medical Center 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 10 inclusion and 12 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 21 Sep 2005. 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. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Maren L Mahowald, MD (6124674190, mahow001@umn.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Pain Score. The study lists 3 primary outcomes in all. 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 21 Sep 2005.
