About this study

Official title: Long-Term Management of "Younger, Active" Patients With Pain From Early Knee Osteoarthritis With Synvisc-One (Hylan G-F 20)

This study aims to study use of viscosupplementation as a treatment of pain for young individuals who are active. Typically viscosupplementation is considered an intervention for knee osteoarthritis often for older patients who are less active. Many young active patients can also develop knee osteoarthritis after trauma or surgery or for congenital reasons. Treatment of these patients commonly are steroid injections which have more biologically detrimental effects for cartilage compared to viscosupplementation Synvisc One injections which are a single injection will be used to determine effectiveness of reducing pain and maintaining an active healthy lifestyle for younger patients aged 30-50 years old.

Read the detailed description

This study will be an open label longitudinal cohort study with natural history over 3 years. Screening data will be reviewed to determine subject eligibility. Subjects who meet all inclusion criteria and none of the exclusion criteria will be entered into the study. Subjects enrolled in the cohort will have baseline functional testing performed including a motion gait analysis, 12 minute walk test, and 3-day accelerometer data. Subjects will receive a single 6 mL intra-articular injection of hylan G-F 20 in the target knee at baseline. All ongoing treatments will be monitored at 6 month intervals over the 3 year duration of the study. Patients can receive any other conservative treatments (e.g., oral medications, physical or other therapy, acupuncture, etc., except other injection treatments) and current treatments will be documented during each patient encounter. An initial injection of hylan G-F 20 will be injected in the symptomatic knee using a standard supine lateral approach using a 20 gauge needle. A face to face follow up visit will be carried out 6 months after first injection with additional face to face meetings every 6 months thereafter unless the subject requires an additional injection of hylan G-F 20. Hylan G-F 20 treatments can be administered up to three times each year during the study duration. After each injection, follow up measures will be carried out using secure e-mail or phone contact at 6 weeks, 12 weeks, 18 weeks after each in-office evaluation or injection. Follow up will consist of WOMAC, Lysholm score, and Tegner score. Patients may return for retreatment of hylan G-F 20 if symptoms recur after at least 4 months following their previous injection and they meet the inclusion criteria with pain levels of WOMAC A1, C8, C9, C10 and/or C23 equaling 2 or more. Patients requiring three injections of hylan G-F 20 in 4 months or less will be allowed to exit the cohort after their six-month follow up following the third injection. Otherwise, patients will be followed until they reach the 3 year follow up, or drop out for other injection treatments or surgical treatment. Therefore, patients would potentially be able to receive up to 9 injections during the 3 year study.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Synvisc-One (G-F 20)Device

    Synvisc G-F 20 will be injected in the symptomatic knee using a standard supine lateral approach using a 20-gauge needle. Patients will be treated at baseline and followed out to three years. Patients may return for retreatment as early as 4 months post their prior injection if they meet the retreatment criteria pain levels for Worst Knee Pain. If the subjects need another injection, the follow-up cycle will restart at Visit 1 and the subject will be seen every 6 months and followed-up for 3 years.

What is being measured

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

  1. "Worst Knee Pain" Likert Scale (0-10) Reported on Survey

    Worst Knee Pain Scores were measured using a "Worst Knee Pain" Likert scale, the score ranges from 0-10, zero indicating no pain and 10 indicating the worst pain.

    Patient Acceptable Symptom State (PASS) is a "Worst Knee Pain" reported score of less than 4 to be "positive". Patient Acceptable Symptom State (PASS) is the highest level of symptom beyond which patients consider themselves well.

    Minimum Clinical Important Improvement (MCII) is improvement at any time in the 26 week time frame that "Worst Knee Pain" is reported at 2 points less than baseline.

    Measured: 26 weeks after injection at baseline

Secondary outcomes (3)
  1. Patient Acceptable Symptom Score (The Effect of Repeated Treatments)

    Though symptoms can be improved for periods up to 6 months, pain symptoms can recur. The effect of repeated treatments of hylan G-F 20 will be studied with the Patient Acceptable Symptom Score less than 4/10 for the reported Worst Knee Pain score on follow up surveys.

    Worst Knee Pain Scores were measured using a "Worst Knee Pain" Likert scale, the score ranges from 0-10, zero indicating no pain and 10 indicating the worst pain.

    Patient Acceptable Symptom State (PASS) is a "Worst Knee Pain" reported score of less than 4 to be "positive". Patient Acceptable Symptom State (PASS) is the highest level of symptom beyond which patients consider themselves well.

    Measured: 26 weeks post-injection Number 2, an average of 52 weeks

  2. Minimal Clinical Important Improvement (The Effect of Repeated Injections)

    Though symptoms can be improved for periods up to 6 months, pain symptoms can recur. The effect of repeated treatments of hylan G-F 20 will be studied with the Minimal Clinical Important Improvement less than 2 points from baseline on a 10-point likert scale for the reported Worst Knee Pain score on any follow up survey within 3 months. Worst Knee Pain Scores were measured using a "Worst Knee Pain" Likert scale, the score ranges from 0-10, zero indicating no pain and 10 indicating the worst pain. Patients can reinject after 4 months.

    Measured: up to 15 months (within 3 months from the second Synvisc One injection)

  3. Identify the Effects of Treatment on Activity Levels

    To identify the effects of treatment with hylan G-F 20 on activity levels (using objective activity measures utilizing accelerometer and Physical Activity Enjoyment Scale (PACES) and quality of life scores (WOMAC, SF-12) comparing baseline to treatment at 3 months.

    Measured: 26 weeks post-injection at baseline through 3 years post-injection

What does the primary outcome measure?

"Worst Knee Pain" Likert Scale (0-10) Reported on Survey (time frame: 26 weeks after injection at baseline). 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 7 May 2021.
