Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Double Blind (Subject, Investigator)

Further study details as provided by Brigham and Women's Hospital:

Primary Outcome Measures:
  • Change from baseline in mean pain intensity scores on the NRS. [ Time Frame: 4 Weeks ]
    The primary efficacy endpoint will be the comparison of the overall pain intensity on the NRS for the last 7 days of each treatment period. (V158866 compared to placebo)

  • Safety and tolerability of V158866 compared to placebo [ Time Frame: 4 weeks ]

    Safety and tolerability measured by:

    Adverse events, Columbia Suicide Severity Rating Scale change from baseline, Vital signs change from baseline, 12-lead ECG change from baseline, Beck Depression Inventory change from baseline, Laboratory safety tests changes from baseline, ARC Inventory - marijuana change from baseline, RBANS change from baseline

Secondary Outcome Measures:
  • Gracely pain scores [ Time Frame: 4 weeks ]
    Gracely pain scores will be compared between V158866 and placebo treatment.

  • Sleep interference [ Time Frame: 4 weeks ]
    Sleep interference scores will be compared between treatment with V158866 and placebo.

  • Quantitative Sensory Testing [ Time Frame: 4 weeks ]
    Quantitative Sensory Testing parameters will be compared between treatment with V158866 and placebo
