Description
Inclusion Criteria:
- Age >18
- Distal symmetric pain distribution (both feet, with or without pain in hands).
- The pain appeared during or up to 12 weeks after treatment with oxaliplatin, paclitaxel, docetaxel or any combination of these.
- Score of 4 or more on DN4 (Douleur Neuropathique 4) neuropathic pain questionnaire
- Pain duration > 2 months.
- Patient report of average daily pain intensity in the last week >3 on 0-10 Numerical Rating Scale (NRS).
- Women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control, abstinence) prior to study entry and for the duration of study participation.
- Able and willing to sign an IRB-approved written informed consent.
Exclusion Criteria:
- Hypersensitivity to pregabalin.
- Current treatment with pregabalin.
- Current treatment with a vinca alkaloid (e.g. vincristine, vinblastine), or CIPN that may be associated with previous treatment with a vinca alkaloid.
- History of diabetes mellitus or a neurological disorder with any previous signs of distal symmetric polyneuropathy.
- Moderate to severe renal failure (Creatinine clearance < 30mL/min, by Cockcroft-Gault formula).
- ALT (alanine aminotransferase) or AST (aspartate aminotransferase ) > 3 times the upper limit of normal.
- Planned surgeries or radiation treatment within 10 weeks following study inclusion.
- Inability to complete pain self-report.
- Pregnancy or lactation
- Patients with seizure disorders treated with anticonvulsants
- Current participation in a trial with another investigational agent.
Concomitant medication as follows:
- Subjects treated with gabapentin or other anticonvulsant for neuropathic pain will be required to taper the medication and discontinue for at least 2 weeks prior to study initiation.
- Patients on antidepressant treatment for pain or depression (TCAs, SSRI, SNRIs etc. will be allowed to continue their medications provided they have been on a stable dose for at least 4 weeks before study initiation. No dose regimen changes of antidepressants will be allowed during the study period.
- Patients on around-the clock opioid treatment (including tramadol) will be allowed to continue their medication provided they have been on a stable dose for at least 4 weeks before study initiation. The maximum allowed dose of opioid will be equivalent to 60mg oral morphine sulphate. Patients with higher doses will be required to taper down their opioid dose to maximum 60mg oral morphine equivalent, and continue on stable dose for 4 weeks before enrollment in the study. Short-acting opioids for painful CIPN treatment will not be allowed.
- Treatment with non-steroidal anti-inflammatory drugs (NSAIDs) will be discontinued at least 2 weeks before study initiation. However, low-dose aspirin (≤325mg/day) will be allowed.

Primary Outcome Measures
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Change in Spontaneous Pain Intensity as a Function of Baseline MPT
Time Frame: Baseline to week 4
|
Correlation between Mechanical Pain Threshold (MPT in mN) at baseline and reduction in spontaneous pain intensity (% reduction on 0-10 NRS) at the end of 4-week treatment.
The slopes (Pearson coefficients) of the correlation obtained from pregabalin vs. placebo will be compared.

Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Absolute Change in Pain Intensity, Measured on 0-10 Numerical Rating Scale (NRS)
Time Frame: Baseline to week 4
|
Absolute change in pain intensity on 0-10 numerical rating scale (NRS) from baseline to 4 weeks with pregabalin vs. placebo NRS: 0= no pain, 10= worst pain
|
Baseline to week 4
|
|
Change in NPSI Outcomes
Time Frame: Baseline to week 4
|
Change from baseline to week 4 in total NPSI (Neuropathic Pain Symptom Inventory) score The total NPSI score is comprised by adding 5 sub-scores (Burning pain, Pressing pain, Paroxysmal pain, Evoked pain, and Paresthesia/Dysesthesia) and is expressed on a 0-100 scale; 0-minimum (least), and 100 maximum (worst) score
|
Baseline to week 4
|
|
Change in BPI Outcomes (SEVERITY)
Time Frame: Baseline to week 4
|
Change from baseline to week 4 in BPI (Brief Pain Inventory) pain severity severity score BPI severity score is expressed on 0-10 scale, with 0 being the minimum (least), and 10 being the maximum (worst) pain severity
|
Baseline to week 4
|
|
Change in Sleep Problem Index (SPI) Outcomes
Time Frame: Baseline to week 4
|
Change from baseline to week 4 in SPI (Sleep Problem Index) score, on 0-100 scale, where 0= best (least) score, and 100= maximum (worst) score
|
Baseline to week 4
|
|
Change in BPI Outcomes (INTERFERENCE)
Time Frame: baseline to week 4
|
Change from baseline to week 4 in BPI (Brief Pain Inventory) pain interference score BPI interference score is expressed on 0-10 scale, with 0 being the minimum (least), and 10 being the maximum (worst) pain interference
|
baseline to week 4
|
|
Number of Patients With Significant Pain Reduction
Time Frame: Baseline to week 4
|
Number of patients who experienced 50% or more reduction in average daily pain (on 0-10 NRS, Numerical Rating Scale, where 0=least pain, 10=worst pain)
|
Baseline to week 4
