About this study

Official title: Milnacipran for the Pain, Sensory Sensitization and Mood Changes in Knee Osteoarthritis

The patients are asked to take part in this study because you have chronic pain as a result of knee osteoarthritis. This study is done to investigate the pain relieving effects of the study drug Savella (milnacipran HCl) for people who experience chronic osteoarthritis pain. The purpose of this research is to look at how the study drug can be used to benefit people who experience osteoarthritis knee pain. This is a phase IV study done to study the safety and effectiveness of the drug. At this point the drug is already approved by the Food and Drug Administration for people with fibromyalgia but it has not yet been approved for people with knee osteoarthritis.

Read the detailed description

If you are in this study, you will be placed in one of two study groups: one group will receive the study drug and one will receive a placebo. You will be assigned a study group by chance using a process similar to the flip of a coin.

At the first visit (week one) we will review and sign the informed consent, obtain your medical health history, and conduct a brief physical exam. You will also complete several questionnaires about your pain. You will be assessed for your eligibility to participate in this study. If you are eligible, we will conduct some physical and sensory tests and collect a blood sample. The physical tests include a stair climb, 6-minute treadmill test and a 1-minute sit to stand test. The sensory tests allow us to understand your perception of various stimuli such as vibration, light touch, pinprick, heat, cold, hot pain, and cold pain. At the end of the first visit you will be given an electronic diary to record your pain throughout the study. We will also ask you to wear a device in a T-shirt, similar to an accelerometer, that will be used to record your sleep quality and physical activity for 2 days.

At the second (week two) and third visits (week nine) you will be asked to complete the same questionnaires, physical and sensory tests as during the first visit. You will also have to wear the t-shirt with the device for 2 days after each visit.

What participants receive

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

  • MilnacipranDrug

    Also called Savella (milnacipran HCL) Tablets

    Total target dose of 200 mg/day. Subjects will titrate-up according to the following schedule: 25 mg/d (2 pills, 2 days), 50mg mg/d (4 pills, 2 days), 100mg/d (2 pills, 3 days), 150 mg/d (3 pills, 4 days), and steady state is reached once the study participant ingests 200 mg/d(4 pills). The steady state is maintained for 44 days (approx. 6 weeks). If intolerable side effects occur, the dose may be reduced to last tolerable does, a minimum of 100 mg/day at the discretion of the PI. Subjects unable to tolerate 100 mg/day will be discontinued from the study. A 2-week down-titration will be used.

  • PlaceboDrug

    Also called "Sugar Pill"

    Subjects will receive identical placebo pills and dosing schedule as that of participants receiving active study medication.

What is being measured

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

  1. McGill Pain Questionnaire - Short Form

    The MPQ-SF is a well-validated pain measure that permits separation of the sensory and affective components of pain, which are added together to compute a total score. The scale ranges from 0-45 (0=no pain, 45=the most pain).

    Measured: Collected at 2 visits over 11 weeks: Visit 1 and Visit 3.

  2. PamSys Actigraph Data

    We used a body worn sensor (PAMSys™, Biosensics, LLC, MA)(25-27) embedded in a comfortable t-shirt at the sternal level. Participants wore the PAMSys after the visit for 48 hours. The device provides values related to subjects spontaneous physical activity including percentage of time standing and walking. These variables provide different indexes of participants' level of activity and activity organization, and were reported by subjects with KOA pain as relevant.

    Measured: 48 hours after visit 3

  3. Pain Anxiety Symptoms Scale (PASS)

    Anxiety scores were collected at least two data points. The Pain Anxiety Symptoms Scale (PASS) is a scale from 0 - 100, where 0 = no anxiety and 100 = the most anxiety.

    Measured: Collected at 2 visits over 11 weeks: Visit 1 and Visit 3.

  4. Pain Disability Index (PDI)

    The PDI is a seven-item, validated instrument that assesses perceived disability in seven key life areas. It provides a total disability score, and is an indirect measure of self efficacy. The Pain Disability Scale is a scale from 0 - 70, where 0 = no Disability and 70 = the most Disability.

    Measured: Collected at 2 visits over 11 weeks: Visit 1 and Visit 3.

  5. Center for Epidemiological Studies Depression Scale CESD-10 (CES-D 10)

    The CES-D 10 is a 10-item questionnaire that has been validated for the assessment of depressive symptomatology. The Depression Scale is a scale with a sum score from 0 - 30, where 0 = no Depression and 30 = the most Depression.

    Measured: Collected at 2 visits over 11 weeks: Visit 1 and Visit 3.

  6. Pain Visual Analogue Scale

    Pain Visual Analogue Scale from 0-100 (0= no pain, and 100= most pain).

    Measured: Collected at 2 visits over 11 weeks: Visit 1 and Visit 3.

Secondary outcomes (1)
  1. Daily Diary Entries With Pain, Fatigue and Functioning Scores Three Times a Day

    Averages of daily diary outcomes were taken over the first and last week of the trial (week 1 and week 11) to compare pre and post treatment. diary was filled out 3 times a day and asked subjects to rate pain at rest, pain when walking, and fatigue on a scale 0-10 (0=none, and 10=the worst)

    Measured: electronic diary entries with pain, fatigue and functioning scores were completed three times a day during week 1 and week 11

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Milnacipran in people with Knee Osteoarthritis and Degenerative Joint Disease, run by Dr. Norman Harden.

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 9 inclusion and 9 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 22 Jun 2015. Status can change between updates, so confirm with the study contact before making plans.

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 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?

Yes. Results are posted in the registry (first posted 22 Jan 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

McGill Pain Questionnaire - Short Form (time frame: Collected at 2 visits over 11 weeks: Visit 1 and Visit 3.). The study lists 6 primary outcomes in all. 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 NCT01510457, which also lists 1 linked publication.

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 22 Jun 2015.
