Further study details as provided by Pfizer:

Primary Outcome Measures:
  • Changes in voxel-wise Blood Oxygen Level Dependent (BOLD) signal throughout the brain and changes in pre-defined brain regions of interest. [ Time Frame: 22 days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Whole brain resting-state distribution of Cerebral Blood Flow [ Time Frame: 22 days ] [ Designated as safety issue: No ]
  • Psychometric measures of pain, namely Daily Pain Diaries and Present Pain Intensity [ Time Frame: 22 days ] [ Designated as safety issue: No ]
  • Pain induced by a grip task measured with a Visual Analogue Scale (VAS), the Short-Form McGill Pain Questionnaire and patient-rated wrist/hand evaluation (PRWHE) [ Time Frame: 22 days ] [ Designated as safety issue: No ]
