A Study Of Celecoxib Versus Diclofenac In Patients With Ankylosing Spondylitis
- Conditions
- Ankylosing Spondylitis
- Interventions
- Registration Number
- NCT02528201
- Lead Sponsor
- Pfizer
- Brief Summary
A clinical trial to assess the effect of celecoxib 200 milligrams (mg) once daily and 400 milligrams (mg) once daily compared to diclofenac three times daily in the treatment of Ankylosing Spondylitis (AS) for 12 weeks. This will be used to confirm the results of a prior 6 week trial.

- Current painful vertebral compression.
- Requirement to start physiotherapy, re-education or manipulation

- Cardiac failure or known renal insufficiency that could be affected by study medication, chronic or acute hepatic insufficiency, significant coagulation disorders or history of asthma.
- Current or history of malignancy (except: patients having a basal cell carcinoma or other malignancy operated on and in remission for 5 years before inclusion in the trial).
- Pregnancy, women of childbearing potential not using adequate contraceptive methods or nursing mothers.
- Subject who has evidence of alcohol or drug abuse.
- Participation in any other clinical study within 30 days prior to the screening visit.

- Taking the following medications: Muscle relaxants, hypnotic, anxiolytics, sedatives, tranquillizers or antidepressants (unless stable for 2 weeks before screening and continuing throughout the trial), NSAIDs or COX-2 inhibitors other than study medication, acetylsalicylic acid (ASA) > 160 mg /day, anti-coagulants, ticlopidine, lithium, anti-TNF agents or methotrexate > 15 mg/week (Note: ASA ≤ 160 mg/day for cardioprotection is permitted), Use of oral or systemic analgesic medication, except from paracetamol, within 3 days of study entry and through the study, Corticosteroids (PO/IM/IV/IA) in the 6 weeks preceding inclusion in the trial, Anti-ulcer medication including chronic (daily or almost daily) use of antacids [Note: Occasional use of antacids during the study will be permitted.]
- Change in dose of a slow-acting drug (e.g. sulfasalazin, methotrexate) in the past 60 days preceding inclusion in the trial.
- Taking paracetamol > 2000 mg/day (including during the screening period).

- Primary Outcome Measures
Name Time Method Change in baseline of Patient Global Assessment of Pain Intensity (VAS) at week 12 Baseline, Week 12 Global Pain Intensity score (VAS): is a participant reported assessment of pain on a 0 to 100 millimeter (mm) Visual Analog Scale (VAS) where 0 mm= no pain and 100=most severe pain.
- Secondary Outcome Measures
Name Time Method Participants Global Assessment of Pain Intensity (VAS) Weeks 2, 6 Global Pain Intensity score (VAS): is a participant reported assessment of pain on a 0 to 100 millimeter (mm) Visual Analog Scale (VAS) where 0 mm= no pain and 100=most severe pain.
Bath Ankylosing Spondylitis Functional Index (BASFI) Weeks 2, 6 BASFI is a validated self assessment tool that determines the degree of functional limitation in AS. Utilizing a VAS of 0-10 (0 = easy, 10 = impossible), participants answered 10 questions assessing their ability in completing normal daily activities or physically demanding activities. The BASFI score is a mean score of the 10 questions.
Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) Weeks 2, 6 BASDAI is a validated self assessment tool used to determine disease activity in participant with Ankylosing Spondylitis (AS). Utilizing a Visual Analog Scale (VAS) of 0-10 (0=none and 10=very severe) participant's answered 6 questions measuring discomfort, pain and fatigue. The final BASDAI score averages the individual assessments for a final score range of 0-10
Participants and Physicians Global Assessment of Disease Activity Weeks 2, 6, 12 Participants are asked at each visit the following questions: Taking everything into account how do you assess the activity of your disease in the last 2 days on a scale where: 0=disease inactive with no symptoms and 100=disease extremely active?
Participants and Physicians Global Assessment of Treatment Week 12 The patients will be asked up to four global questions about safety and efficacy of the trial medication and about their current disease status. Responses are done on a 5 point scale where 0=no effect, 1=poor effect, 2=moderate effect, 3=good effect, and 4=excellent. At the same visits the investigator will be asked to do his/her own judgment of the efficacy and tolerance of the treatment (excellent, good, moderate, poor).
Participants Consumption of Rescue Medication Baseline, Weeks 2, 6, 12 Participant consumption of rescue medication (paracetamol) calculated at each individual visit (except from the screening visit) by counting returned tablets versus tablets dispensed at the previous visit.
