Painful Diabetic Neuropathy – Current Treatment – Detailed. Expanded Analysis: Treatment Algorithms – Claims Data Analysis (US)

Painful diabetic neuropathy (PDN) afflicts more than three million people in the United States. It characterized by numbness, tingling, and burning, sharp, shooting or other painful sensations, commonly in the feet, legs, and/or hands. PDN is managed with multiple well-established, generic treatment options. Antidepressants (e.g., tricyclic antidepressants, serotonin / norepinephrine reuptake inhibitors), antiepileptic drugs (e.g., gabapentin), nonsteroidal anti-inflammatory drugs (NSAIDs), and opioid-based drugs are all used to treat PDN patients. However, current analgesics do not offer adequate pain relief, leaving unmet need and opportunity for new options, especially novel mechanisms of action, in this arena. The successful launch of a novel analgesic requires a granular understanding of treatment patterns in this crowded and highly generic market.


  • What patient shares do key therapies and brands garner by line of therapy in newly diagnosed PDN patients? What are the quarterly trends in prescribing among recently treated and newly diagnosed PDN patients?
  • How have branded agents offering incremental safety, tolerability, or dosing benefits fared in this highly generic market? How have they been integrated into the treatment algorithm, and what is their source of business?
  • What percentage of PDN patients receive drug therapy within one year of diagnosis, and how quickly? What percentage of patients progress to later lines of therapy within one year of diagnosis?
  • What percentage of PDN patients are treated with monotherapy vs. combination therapy? What are the most used combinations?
  • What are the product-level compliance and persistency rates among drug-treated patients?
