Market Opportunity

MetricValueContext
Neuropathic Pain Prevalence150‑200 million patients globally; 20‑30 million in USHigh unmet need, limited effective therapies
Current SOCPregabalin, gabapentin, duloxetine, TCAs30‑50% of patients have inadequate relief
Combination Therapy GapNo FDA‑approved combos for neuropathic painY‑4 addresses polypharmacy need in single tablet
Peak Sales Potential$500‑800 million (global estimate)10‑15% share of refractory neuropathic pain market
Fast Track AdvantageExpedited FDA review, potential for accelerated approvalReduces development timeline by 1‑2 years

Strategic Implications

  • For Neurodawn: Fast Track designation validates first‑in‑class profile; pregabalin/riluzole combo creates high‑barrier IP; monetization pathway via global licensing or direct commercialization in US/EU.
  • For Patients: Synergistic analgesia expected to improve pain control vs. monotherapy; oral tablet improves compliance; addresses refractory cases that fail existing agents.
  • For Market: Demonstrates China’s biotech innovation in CNS/pain management; combination therapy trend extends to neuropathic pain; Fast Track signals strong clinical rationale and FDA confidence.
