  Purpose

The purpose of this study is to determine the safety and efficacy of bilateral intramuscular injections of VM202 versus placebo in the treatment of painful diabetic neuropathy.

A total of 477 subjects will be randomized in a 2:1 ratio to one of two treatment groups:

Treatment - VM202 - 318 subjects Control - Placebo (VM202 vehicle) - 159 subjects

Randomization will be stratified by current use of gabapentin and/or pregabalin.

Detailed Description:
Peripheral neuropathy is a serious complication of diabetes. This form of neuropathy carries a high risk of pain, trophic changes and autonomic dysfunction. Treatment of diabetic peripheral neuropathy (DPN) is based on either pathogenetic mechanisms or symptomatic relief. A number of clinical trials have established symptomatic treatment but for pathogenetic mechanisms, the only proven treatment strategy is strict glycemic control. Clearly, it would be desirable to prevent, impede, or reverse the disrupting and often life-threatening manifestations of peripheral neuropathy by stimulating growth or regeneration of peripheral nerve axons. The results from previous studies suggest that VM202 provides the same magnitude of pain relief as reported with pregabalin or gabapentin.

  3. No significant changes anticipated in diabetes medication regimen;
  4. No new symptoms associated with diabetes within the last 3 months prior to study entry;
  5. Diagnosis of painful diabetic peripheral neuropathy in both lower extremities;
  6. Lower extremity pain for at least 6 months;
  7. Visual analog scale (VAS) score of ≥ 40 mm at Initial Screening (0 mm = no pain - 100 mm very severe pain);
  8. Symptoms from the Brief Pain Neuropathy Screening (BPNS) is ≤ 5 point difference between legs at Initial Screening;
  9. The average daily pain intensity score of the Daily Pain and Sleep Interference Diary completed after medication wash-out is ≥ 4 with a standard deviation ≤ 2;
  10. The physical examination component of the Michigan Neuropathy Screening Instrument Score (MNSI) is ≥ 3 at Initial Screening;
  11. Subjects on gabapentin (Neurontin), pregabalin (Lyrica), duloxetine (Cymbalta) for painful DPN at study entry must be on stable regimen of these treatments for at least 3 months prior to study entry; and
  12. If female of childbearing potential, negative urine pregnancy test at screening and using acceptable method of birth control during the study.

Exclusion Criteria:
