Experimental: COV155
COV155, loading dose of 3 tablets followed by 2 tablets every 12 hours for 48 hours.
Drug: COV155
COV155 tablets
Other Name: MNK155

Placebo Comparator: Placebo
Matching tablet to COV155 without containing active ingredients, loading dose of 3 tablets followed by 2 tablets every 12 hours for 48 hours.
Drug: placebo

Primary Outcome Measures :
  1. SPID48 (Summed pain intensity difference) [ Time Frame: 48 hours ]
    48 hour Summed pain intensity difference

Secondary Outcome Measures :
  1. Safety and tolerability of COV155 [ Time Frame: 48 hours ]
    Safety and tolerability to be evaluated with physical exams, vital signs, pulse oximetry, clinical laboratory tests, electrocardiograms, and adverse events

  2. Onset of analgesia of COV155 versus placebo [ Time Frame: 48 hours ]
    Onset of confirmed perceptible pain relief, time to meaningful pain relief, and time to peak pain intensity difference

  3. Analgesic effects of COV155 versus placebo [ Time Frame: 48 hours ]
    Pain intensity scores, pain intensity differences, and summed pain intensity differences; pain relief scores and total pain relief; percent responders; mean dosing interval; use of rescue medication; global assessment of subject satisfaction with study treatment.
