Primary Outcome Measures
NameTimeMethod
Number of Flare Events Per Time of Exposure to Study MedicationPeriod III (22 weeks)

Number of flare events per month during Period III (calculated as number of flares divided by number of months participant was enrolled during Period III). Flare was determined using pre-defined criteria, using an interactive voice response system.

Secondary Outcome Measures
NameTimeMethod
Physician's Global Assessment of Arthritis at Final VisitPeriod III (22 weeks)

Physician assessed each participant's disease symptoms on a categorical scale from 1 (very good) to 5 (very poor).

Total Rescue Medication Taken (Mean)Period III (22 weeks)

Total amount of rescue medication (acetaminophen in milligrams \[mg\]) taken per month per participant

Days on Flare MedicationPeriod III (22 weeks)

Number of days on flare medication per month per subject calculated as number of days on flare medication divided by the number of days on study medication in Period III

Change in Western Ontario and McMaster Universities (WOMAC) Osteoarthritis ScoresPeriod III (22 weeks)

Score at end of Period III minus score at start of Period III. WOMAC assesses subject responses to 24 components regarding subscales of pain, stiffness and physical function (score range: 0=none to 4= extreme). Total score is sum of the 3 subscale scores. Negative change indicates improvement.

Time to Occurrence of First Osteoarthritis (OA) FlarePeriod III (22 weeks)

Time from first dose of double blind medication (start of Period III) to occurrence of first OA flare. Flare was determined using pre-defined criteria, using an interactive voice response system

Proportion of Days Free From Osteoarthritis (OA) FlarePeriod III (22 weeks)

Number of days subject was free from OA flare divided by number of days on study medication in Period III. Flare was determined using pre-defined criteria, using an interactive voice response system.

Patient's Global Assessment of ArthritisPeriod III

Participant's response to question "Considering all the ways the osteoarthritis in your hip or knee affects you, how are you doing today?" on scale from 1 (very good) to 5 (very poor). Scores analyzed as area under the curve (AUC) of participant's scores from each assessment in Period III.

Area Under the Curve (AUCs) of Western Ontario and McMaster Universities (WOMAC) Osteoarthritis ScoresPeriod III (22 weeks)

WOMAC assesses subject responses to 24 components regarding subscales of pain, stiffness and physical function (score range: 0=none to 4= extreme). Total score is sum of the 3 subscale scores. Scores analyzed as area under the curve (AUC) of participant's WOMAC scores from each assessment in Period III.

Proportion of Days in Osteoarthritis (OA) FlarePeriod III (22 weeks)

Number of days subject was in OA flare divided by number of days on study medication in Period III. Subjects may have more than one flare. Flare was determined using pre-defined criteria, using an interactive voice response system.

Arthritis Pain Numerical Rating Scale (NRS)Period III

Participant rated intensity of osteoarthritis pain on categorical scale from 0 (no pain) to 10 (worst pain). Scores analyzed as area under the curve (AUC) of participant's scores from each assessment in Period III.

Proportion of Days on Rescue MedicationPeriod III (22 weeks)

Days on rescue medication divided by number of days on study medication in Period III
