  • Opioid analgesics, non-opioid analgesics, non-steroidal anti-inflammatory drugs, anticonvulsants, antidepressant drugs and other non-drug therapies may be continued provided that the subject is on stable doses/regimens for at least four weeks prior to the start of the Treatment Phase (Visit 2).
  • Able to adhere to the study visit schedule and other protocol requirements.
  • Women of childbearing potential (WCBP) must agree to practice complete abstinence from heterosexual intercourse or to use two methods of contraception beginning 4 weeks prior to the start of study drug (Day 1) while on study drug (including dose interruptions) and 4 weeks after the last dose of study drug. The two methods of contraception must include one highly effective method (i.e. intrauterine device [IUD], hormonal [birth control pills, injections, or implants only if used in conjunction with a low-dose (81 mg/day) aspirin regimen], tubal ligation, partner's vasectomy) and one additional effective (barrier) method (i.e. latex condom, diaphragm, cervical cap). If a hormonal method (birth control pills, injections, or implants) or IUD is not medically possible for the subject, two of the barrier methods will be acceptable.
  • Women of childbearing potential (WCBP) must have two negative pregnancy tests (sensitivity of at least 50 mlU/mL) prior to starting study drug treatment. The first test should be performed within 10-14 days and the second within 24 hours of starting study drug. Once treatment has started, it is recommended that subjects have weekly pregnancy test during the first 4 weeks of treatment. Thereafter, subjects are required to have pregnancy testing every 4 weeks in females with regular menstrual cycles and every 2 weeks in females with irregular cycles.
  • Males (including those who have had a vasectomy) must use barrier contraception (latex condoms) when engaging in reproductive sexual activity with WCBP while on study drug and for 4 weeks after the last dose of study drug.

About this study

Official title: A Multicenter, Double-Blind, Placebo-Controlled Study to Evaluate the Efficacy and Safety of Lenalidomide in the Treatment of Complex Regional Pain Syndrome Type 1

The purpose of this multicenter, double-blind, placebo-controlled study is to evaluate the efficacy and safety of Lenalidomide in adult subjects with Complex Regional Pain Syndrome (CRPS) Type 1.

Read the detailed description

This is a multicenter, double-blind, placebo-controlled study in adult subjects with Complex Regional Pain Syndrome (CRPS) Type 1.

One hundred eighty (180) subjects diagnosed with unilateral CRPS Type 1 will be enrolled and randomized to receive orally either 10 mg/day of lenalidomide or placebo (90 subjects per treatment arm). For each subject, the study consists of three phases: Pre-randomization Phase (2 weeks), Treatment Phase (12 weeks) and Extension Phase where subjects have the opportunity to receive lenalidomide treatment as long as a benefit is derived from the drug. Subjects who complete all 12 weeks of the treatment phase may be eligible to receive lenalidomide in the extension phase. Subject may continue in the extension phase as long as a benefit is derived from the drug.

What is being measured

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

  1. Percentage of Participants Who Have a >= 30% Reduction (Improvement) in the Complex Regional Pain Syndrome (CRPS) Pain Intensity Numeric Rating Scale (PI-NRS) Score From Baseline to the Last Assessment

    Participants rated the intensity of pain in the CRPS-affected limb twice each day in a diary. The PI-NRS is an eleven point scale with 0=no pain and 10=worst pain imaginable. Responders are participants who completed 12 weeks of treatment and their week 12 PI-NRS score showed at least a 30% improvement from baseline. Participants who did not complete 12 weeks of treatment are considered non-responders.

    Measured: Day 0, Week 12

Secondary outcomes (16)
  1. Change From Baseline in the Total Score of the Short Form McGill Pain Questionnaire (SF-MPQ) at Week 12

    Short Form McGill Pain Questionnaire (SF-MPQ) is comprised of 15 pain qualities that are rated by the participant on a 4 point scale with 0=none and 3=severe. The scale for the Total Score is 0-45. Week 12 values are compared to baseline values. Negative changes indicate improvement in level of pain.

    Measured: Day 0, week 12

  2. Change From Baseline in the Complex Regional Pain Syndrome (CRPS) Pain Intensity Numeric Rating Scale (PI-NRS) Score Using Averaged Morning and Evening Readings at Week 12

    Participants rated the intensity of pain in the CRPS-affected limb twice each day in a diary. Morning and evening scores are averaged. The PI-NRS is an eleven point scale with 0=no pain and 10=worst pain imaginable. Week 12 values are compared to baseline values. Negative changes indicate improvement in level of pain.

    Measured: Day 0, week 12

  3. Change From Baseline in the Morning Complex Regional Pain Syndrome (CRPS) Pain Intensity Numeric Rating Scale (PI-NRS) Score at Week 12

    Participants rated the intensity of pain in the CRPS-affected limb twice each day in a diary. The PI-NRS is an eleven point scale with 0=no pain and 10=worst pain imaginable. The morning pain ratings at baseline and Week 12 are compared. Negative changes indicate improvement in level of pain.

    Measured: Day 0, week 12

  4. Change From Baseline in the Evening Complex Regional Pain Syndrome (CRPS) Pain Intensity Numeric Rating Scale (PI-NRS) Score at Week 12

    Participants rated the intensity of pain in the CRPS-affected limb twice each day in a diary. The PI-NRS is an eleven point scale with 0=no pain and 10=worst pain imaginable. The evening pain ratings at baseline and Week 12 are compared. Negative changes indicate improvement in level of pain.

    Measured: Day 0, week 12

  5. Change From Baseline in Daily Sleep Assessment Average Score at Week 12

    Participants rated how much CRPS pain interfered with their sleep each day in a diary. The Sleep Assessment uses an eleven point scale for four questions. Questions concern ability to fall asleep, ability to stay asleep, how refreshed the participant feels upon waking and how alert the participant is during the day. All use a scale of 0-10, where the higher number is the positive response (e.g. 0=Pain completely interferes with sleep and 10=Pain does not interfere). The mean of all four responses was calculated if at least 3 of the 4 questions had a value. Week 12 values are compared to baseline values. Positive change values indicate improvement.

    Measured: Day 0, week 12

  6. Change From Baseline in Activity Level Rating Using a Numeric Rating Scale (NRS) at Week 12

    Participants rated how the activity level on a given day compares with their activity level prior to the start of treatment. A seven-point scale is used with -3=much worse and +3=much better. Positive change values indicate improvement.

    Measured: Day 0, week 12

  7. Change From Baseline in Participant Assessment of CRPS Symptoms Total Score at Week 12

    Participants rated twelve CRPS symptoms using a four-point rating scale in which 1=the most positive outcome and 4= the most negative outcome for a total scale of 12-48. Week 12 values are compared to baseline values. Negative change values indicate improvement.

    Measured: Day 0, week 12

  8. Change From Baseline in "Mechanically Evoked" (Allodynia) Numeric Rating Scale (NRS) Score at Week 12

    The investigator rated the degree of allodynia on both the CRPS-affected limb on an eleven-point scale where 0=no pain and 10=worst pain imaginable. This outcome compares the baseline values for the CRPS affected-limb to the values at week 12. Negative change values indicate improvement.

    Measured: Day 0, week 12

  9. Difference in Allodynia Rating Between the CRPS-affected Limb and the Normal Limb at Week 12

    The investigator rated the degree of allodynia on both the CRPS-affected limb and the normal (or less-affected) limb on an eleven-point scale where 0=no pain and 10=worst pain imaginable. This outcome compares the values for the CRPS affected-limb to the normal limb at week 12.

    Measured: Week 12

  10. Change From Baseline in the Brief Pain Inventory (BPI) Total Score at Week 12

    Participants completed the Brief Pain Inventory which asks twelve questions that are rated on an eleven-point scale in which 0=most positive outcome and 10=the most negative outcome for a total scale of 0-120. BPI contains questions that concern the level of pain over the last week and the level of pain right now, the extent to which pain interfered with sleep, normal activities, ability to work, relationships, walking etc. Week 12 values are compared to baseline values. Negative change values indicate improvement.

    Measured: Day 0, week 12

  11. Change From Baseline in the Profile of Mood States (POMS) at Week 12

    Participants completed the Profile of Mood States questionnaire that asks participants to rate how each of 65 words reflected their mood in the past week on a 5-point scale with 0=not at all and 4=extremely for a total scale of 0-260. Week 12 values are compared to baseline values. Negative change values indicate improvement.

    Measured: Day 0, week 12

  12. Patient Global Impression of Change (PGIC) at Week 12

    The Patient Global Impression of Change asks the question: Overall, how would you rate your CRPS condition since the start of study drug? Answers are represented on a seven-point scale with -3=much worst and +3=much better.

    Measured: Week 12

  13. Participants Who Had a Change to CRPS Pain Medication During the Treatment Period

    Participants who had any change in CRPS medication during the double-blind treatment period (up to week 12) are summarized. Changes include additions, discontinuations or dosage change of CRPS medication(s).

    Measured: Day 1 to week 12

  14. Change From Baseline in the Maximal Composite Motor Nerve Conduction Velocity at Week 12

    An electrophysiological evaluation using standard electrophysiological and electromyography to measure the speed and extent of nerve conduction. Week 12 values are compared to baseline values for maximal motor nerve conduct velocity.

    Measured: Day 0, week 12

  15. Change From Baseline in the Maximal Composite Sensory Nerve Conduction Velocity at Week 12

    An electrophysiological evaluation using standard electrophysiological and electromyography to measure the speed and extent of nerve conduction. Week 12 values are compared to baseline values for maximal sensory nerve conduct velocity.

    Measured: Day 0, week 12

  16. Participants With Treatment-Emergent Adverse Events in the Double-Blind Period or the Extension Period

    Counts of study participants who had adverse events (AEs) while treated in either the Double-blind or Extension Periods. The NCI Common Terminology Criteria for Adverse Events (CTCAE), Version 3.0 was used by the investigator to grade the severity of the AEs: Grade 1=Mild AE, Grade 2=Moderate AE, Grade 3=Severe AE, Grade 4=Life-threatening or disabling AE, Grade 5=Death related to AE.

    AEs are also summarized by whether they were serious, related to treatment and whether the AE caused treatment to be altered.

    A serious AE (SAE) was any event that resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity or congenital anomaly/birth defect or was an important medical event could have jeopardized the patient's safety or required medical or surgical intervention to prevent one of the outcomes listed above.

    Measured: Day 1 up to week 158
