Further study details as provided by Henry Ford Health System:

Primary Outcome Measures:
  • reduction in severity of AKN as measured by a novel AKN severity scoring system which incorporates number of lesions, size of lesions, type of lesions and associated inflammation. [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Treatment tolerability as measured by 0 to 10 pain scale [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  • treatment safety [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
    This will be assessed by the frequency of adverse events
