Safety, Tolerability and Efficacy Study With a Fixed-Dose Combination (FDC) Ketoprofen Plus Omeprazole

Primary Objective:

To confirm the safety and tolerability of the fixed dose combination of a Non-Steroidal Anti-Inflammatory Drug (NSAID), ketoprofen, associated to a Proton Pump Inhibitor (PPI), omeprazole, in Mexican patients.

Secondary Objective:

To confirm the efficacy of the combination:

* Relief of pain (Visual Analyzed Score (VAS))
* Patients global assessment of disease activity, scored as a scale of 1 (no limitation of normal activities) to 5 (inability to carried out all normal activities)


Eligibility Criteria:
Inclusion criteria:

* Adults suffering from chronic inflammatory conditions, in particular, rheumatoid polyarthritis, ankylosing spondylitis (or related syndromes, such as, Reiters syndrome, psoriatic arthritis,) with a previous history or who are at risk of developing NSAID associated benign gastric ulcers, duodenal ulcers and gastroduodenal erosions in whom continued treatment with NSAIDs is necessary.
* Presenting at the inclusion visit an acute episode of recent onset (\<48 hours) defined by average pain within the last 24 hours \>=50 mm on the Visual Analogue Scale (VAS).

Exclusion criteria:

* Hypersensitivity to ketoprofen or to omeprazole or to another proton-pump inhibitor or to any of the excipients.
* Last trimester of pregnancy.
* History of asthma induced by administration of ketoprofen or similar acting substances, such as other non-steroidal anti-inflammatory agents (NSAIDs) or acetylsalicylic acid.
* Gastrointestinal disorder or surgery leading to impaired drug absorption.
* Evidence of uncontrolled, or unstable cardio- or cerebrovascular disorder, which in the investigator's opinion would endanger a subject if they were to participate in the study.
* Serious blood coagulation disorder including use of systemic anticoagulants.
* Positive test result for H. pylori at screening.
* Recent endoscopy showing any gastric or duodenal ulcer at least 3 mm in diameter with depth.
* Severe hepatic failure.
* Severe renal failure.
* Severe heart failure.
* Patients with asthma associated with chronic rhinitis, chronic sinusitis and/or nasal polyposis.
* Active peptic ulcer.
* Gastrointestinal bleeding, cerebrovascular bleeding or other active bleeding.
* Alcohol consumption or drug abuse.
* Concomitant use with St. Johns wort or atazanavir sulphate.
* Concomitant use of the following medications:

  * NSAIDs including cyclooxygenase-2 selective inhibitors
  * Salicylates
  * Corticosteroids
  * DMARDs
  * Antacids
  * Histamine H2 receptors
  * Misoprostol
  * Other PPI
  * Sucralfate
  * Anticoagulants: Anti-platelet agents and selective serotonin reuptake inhibitors (SSRIs)
  * Lithium:
  * Methotrexate (at doses above 15 mg/week):
* Screening laboratory value for ALT, AST \>2 times the upper limit of normal.
* Other than noted specifically, any screening laboratory value that is clinically significant in the investigator's opinion and would endanger a subject if they were to participate in the study.
* History of malignancy, treated or untreated, within the past 5 years, with the exception of successfully treated basal cell or squamous cell carcinoma of the skin.
* Participation in any study of an investigational treatment in the 8 weeks before screening.
