Further study details as provided by KAI Pharmaceuticals:

Primary Outcome Measures:
  • The effect of KAI-1678 on mean change from baseline in pain intensity at 6 hours (PID 6). [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
    Measurements are made using a qualified pain scale and the change from basline is calculated at 6 hours.


Secondary Outcome Measures:
  • The effect of KAI-1678 on the proportion of subjects achieving at least a 1 point improvement in pain intensity at 6 hours [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
  • The effect of KAI-1678 on patient global response to treatment [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
  • The effect of KAI-1678 on symptoms associated with PHN assessed by the Neuropathic Pain Scale (NPS) [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
  • The number of adverse events as a measure of safety and tolerability of KAI-1678 [ Time Frame: Two weeks ] [ Designated as safety issue: Yes ]
    Frequency of adverse events on each study treatment
