This is a Phase 2 study designed to test the ability of investigational study drug ARRY-371797 to reduce pain in a postoperative pain model (third molar extraction), and to further evaluate the drug's safety. Approximately 250 subjects from the US will be enrolled in this study.

Condition Intervention Phase
Dental Pain Drug: Placebo; oral Drug: ARRY-371797, p38 inhibitor; oral Drug: Celecoxib, COX-2 inhibitor; oral Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment

Further study details as provided by Array BioPharma:

Primary Outcome Measures:
  • Assess the efficacy of the study drug dosed postoperatively in terms of total pain relief (TOTPAR). [ Time Frame: 6 hours post-dose ]
  • Characterize the safety profile of the study drug in terms of adverse events, clinical laboratory tests, electrocardiograms and vital signs. [ Time Frame: Duration of study ]

Secondary Outcome Measures:
  • Assess the efficacy of the study drug (versus placebo and celecoxib) in terms of pain relief measurements [including TOTPAR, total pain intensity (TPI) and time to rescue medication]. [ Time Frame: Duration of study ]

Enrollment: 250
Study Start Date: April 2008
Study Completion Date: June 2008
Primary Completion Date: June 2008 (Final data collection date for primary outcome measure)

Key Exclusion Criteria:

  • Evidence or history of clinically significant dermatologic, hematological, renal, endocrine (e.g. poorly controlled diabetes), pulmonary, gastrointestinal, cardiovascular, hepatic, neurologic, ophthalmologic, or allergic disease (including clinically significant drug allergies that could impact the conduct of this study, but excluding untreated, asymptomatic, seasonal allergies at time of study drug dosing).
