October 6, 2008 updated by: Pfizer

A Multicentre, Double-Blind, Double-Dummy, Randomised Study of the Analgesic Efficacy and Safety of Valdecoxib Compared to Diclofenac Sodium in Patients Undergoing Knee Arthroscopy Procedure for Anterior Cruciate Ligament Reconstruction

To demonstrate non-inferiority of valdecoxib 20 mg twice daily (BID) (with an initial loading dose of 40 mg followed by a second dose of 20 mg on the first day only) with diclofenac sodium delayed release 75 mg BID in analgesic efficacy, in subjects undergoing knee arthroscopy procedure for anterior cruciate ligament (ACL) reconstruction, when administered for 6 (±1) days.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Patients who had undergone an uncomplicated ACL reconstruction procedure and were in satisfactory health were included in the study
  • In addition, they needed to have a baseline pain intensity of ≥ 50 mm on the VAS and "moderate to severe" pain on the categorical scale within 8 hours of the completion of the surgical procedure to be included

Exclusion Criteria:

  • Patient was scheduled to undergo any other surgical procedure, along with the orthopedic procedure, that was expected to produce a greater degree of surgical trauma than the orthopedic procedure alone
  • The patient was undergoing bilateral knee arthroscopy
  • The patient used conventional NSAIDs, COX-2 inhibitors, or Tramadol during the 6 hours preceding surgery, during surgery or subsequent to the end of surgery, until randomization
  • The patient received oxaprozin or piroxicam within one week prior to randomization
  • The patient was required to take muscle relaxants, tricyclic antidepressants, tranquilizers, sedatives, hypnotics and neuroleptics, in the post operative period after the patient was randomized into the study
  • The patient had been treated with patient controlled analgesia subsequent to the end of the surgical procedure

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
