Brief Summary:
The purpose of this trial is to investigate the efficiency of pain relief and the safety of NPC-06 for the neuropathic pain associated with cancer, in addition to explore the effective concentration of NPC-06.

Condition or disease Intervention/treatment Phase
Neuropathic Pain in Cancer Drug: NPC-06 Phase 2

Detailed Description:
The eligible patients will be randomized into three groups, and will receive NPC-06 (high dose), NPC-06 (low dose) or placebo once a day for 7 days.

Primary Outcome Measures :
  1. Improvement of Numeric Rating Scale (NRS) score within 2 hours after administration [ Time Frame: Pre-administration, 30, 60, 90 and 120 minutes post-administration ]
    Average change (slope) of NRS score

Secondary Outcome Measures :

    Change of NRS score, Change of NRS score of persistent pain, Change of maximum pain, at the time of evaluation compared to baseline

  2. Time to event [ Time Frame: 2 hours after initial administration to Day 7 ]
    Time to event analysis of analgesic effect

  3. Improvement of Neuropathic Pain Symptom Inventory (NPSI) score [ Time Frame: Pre-dose, Days 1,2,3,4,5,6,7,8,9,10,11,12,13 ]
    Change of NPSI score compared to baseline

  4. Rescue medication use [ Time Frame: Day 1 to Day 13 ]
    Number of times of rescue medication use

  5. Effective concentration [ Time Frame: Day 0 to Day 13 ]
    Blood phenytoin concentration
