About this study

Official title: A Phase I Single Center Open Label Study to Evaluate the Safety and Efficacy of a Low Level Light Device in Patients With Knee Osteoarthritis

This Phase I study is being conducted to examine the efficacy of the Light Sciences LLC (LSLLC) phototherapy device for home (self) treatment of knee osteoarthritis (OA).

Read the detailed description

This Phase I study is being conducted to examine the efficacy of the Light Sciences LLC (LSLLC) phototherapy device for home (self) - treatment of knee osteoarthritis (OA). Clinical efficacy will be assessed by evaluating the level of reported pain, including the use of analgesics, various measures of functional improvement, and clinical symptomology during a three week period of daily treatments. Durability of the clinical response for twelve weeks following therapy will also be examined. In addition, device safety will be assessed. As this is an early stage-prototype device, subject input regarding the usability of the device will be sought.

Subjects will be required to achieve three weeks of wash-out from all OA therapies prior to the start of phototherapy. Acetaminophen will be allowed during this time. During the three week active treatment and twelve week follow-up periods, subjects will be required to refrain from acetaminophen as well as OA therapies. However, subjects will be encouraged to speak with the investigator should any symptoms become difficult to manage. In addition to clinical assessments, subjects will be required to keep a daily diary.

The clinical objectives of the study will be met if at least five of ten subjects report decreased pain scores and improvement on an osteoarthritis index. While minimum or no safety issues are expected, the occurrence of skin changes to the area exposed to the device will be carefully monitored.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Decreased pain scores on the visual analog scale (VAS)

  2. Improved Western Ontario and McMaster Universities Osteoarthritis index (WOMAC) scores

Secondary outcomes (6)
  1. Reduced use of over the counter (OTC) analgesics post therapy

  2. Improved functionality as determined by measurable increases in knee range of motion (ROM)

  3. Increased exercise ability

  4. No, or decreased knee effusion

  5. Subject satisfaction

  6. Durability of the Clinical Response

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Low level light therapy in people with Osteoarthritis, Knee, run by Light Sciences LLC 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 17 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 14 Aug 2009. 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 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.

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?

Decreased pain scores on the visual analog scale (VAS). The study lists 2 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 14 Aug 2009.
