Osteoarthritis of the KneePhase 211SOHSNCT02156440
Cross-over Study of the Efficacy and Safety of SierraSil Joint Formula 14 in Osteoarthritis of the Knee
A Phase 2 study testing SierraSil Joint Formula 14 in people with Osteoarthritis of the Knee, run by KGK Science Inc. at 1 site in Canada.
Trial summary
Osteoarthritis (OA) affects approximately 10% of people older than 60 years, and compromises the quality of life of more than 21 million North Americans. Studies on the use of complimentary and alternative medicines have reported that OA patients in the US are among the highest users of CAM. Read more about this study

About this study
Official title: A Double Blind, Placebo Controlled Cross Over Study to Explore the Efficacy of SierraSil® Joint Formula 14™ in Adults With Osteoarthritis of the Knee
Osteoarthritis (OA) affects approximately 10% of people older than 60 years, and compromises the quality of life of more than 21 million North Americans. Studies on the use of complimentary and alternative medicines have reported that OA patients in the US are among the highest users of CAM. Previous studies on a unique natural mineral product SierraSil® demonstrated an improvement in joint health and function in subjects with mild to moderate OA of the knee. Extracts of Sierrasil® are reported to reduce cartilage degradation in response to IL-8 and nitric oxide production suggesting an ability to suppress IL-8 mediated events in human cartilage. The primary objective is to assess the efficacy of SeirraSil Joint Formula versus placebo on the symptoms of osteoarthritis as assessed by WOMAC™ Osteoarthritis Index Pain subscale in subjects with osteoarthritis of the knee.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing SierraSil Joint Formula 14 in people with Osteoarthritis of the Knee, run by KGK Science Inc. at 1 site in Canada.
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 28 inclusion and 20 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 5 Jun 2014. 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 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?
WOMAC osteoarthritis index Pain Subscale as a measure of osteoarthritis pain (time frame: 4 weeks). 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 5 Jun 2014.
