Intervention / Treatment
Detailed Description
Objectives:
Primary: To demonstrate that PN400 is effective in reducing the risk of gastric ulcers in subjects at risk for developing NSAID-associated gastric ulcers.
Secondary:
- To determine if PN400 is effective in reducing the risk of duodenal ulcers in subjects at risk for developing NSAID-associated ulcers
- To compare upper gastrointestinal symptoms in subjects treated with PN400 versus naproxen as measured by scores on the Severity of Dyspepsia Assessment (SODA) instrument and the Overall Treatment Evaluation - Dyspepsia (OTE-DP)
- To compare heartburn symptoms in subjects treated with PN400 versus naproxen
- To evaluate the safety and tolerability of PN400 and naproxen

Description
Inclusion Criteria
A subject was eligible for inclusion in this study if all of the following criteria applied:
Male or non-pregnant, non-breastfeeding female subjects with a history of osteoarthritis, rheumatoid arthritis, ankylosing spondylitis or other medical conditions expected to require daily NSAID therapy for at least 6 months, who were
- 18-49 years of age and had a history of a documented, uncomplicated gastric or duodenal ulcer (a mucosal break of at least 3 mm in diameter with depth, without any concurrent bleeding, clot or perforation) within the past 5 years OR, who were
- 50 years of age and older (These subjects did not require a history of a documented, uncomplicated gastric or duodenal ulcer within the past 5 years.)
Female subjects were eligible for participation in the study if they were of
- non-childbearing potential (i.e., physiologically incapable of becoming pregnant);
- childbearing potential, had a negative pregnancy test at Screening, and at least 1 of the following applied or was agreed to by the subject:
- Female sterilization or sterilization of male partner
- Hormonal contraception by oral route, implant, injectable, vaginal ring
- Any intrauterine device with published data showing that the lowest expected failure rate is < 1% per year
- Double barrier method (2 physical barriers or 1 physical barrier plus spermicide)
- Any other method with published data showing that the lowest expected failure rate is < 1% per year
- Each subject was required to understand and comply with study procedures required of a subject and was able and willing to provide written informed consent prior to any study procedures being performed.
Exclusion Criteria
A subject was not eligible for this study if any 1 or more of the following criteria applied:
- History of hypersensitivity to esomeprazole or to another PPI
- History of allergic reaction or intolerance to any NSAID (including aspirin) and/or a history of NSAID-induced symptoms of asthma, rhinitis, and/or nasal polyps
- Participation in any study of an investigational treatment in the 4 weeks before Screening
- Presence of uncontrolled acute or chronic medical illness, e.g., GI disorder, hypertension, diabetes, thyroid disorder, depression and/or infection that would have endangered a subject if they were to have participated in the study
- GI disorder or surgery leading to impaired drug absorption
- Evidence of uncontrolled, or unstable cardio- or cerebrovascular disorder, which in the investigator's opinion would have endangered a subject if they were to have participated in the study
- Schizophrenia or bipolar disorder
- Use of any excluded concomitant medication (see Section 9.4.8)
- A recent history (in the past 3 months) suggestive of alcohol or drug abuse or dependence, including overuse/abuse of narcotics for management of pain
- Serious blood coagulation disorder, including use of systemic anticoagulants
- Positive test result for H. pylori at Screening
- Screening endoscopy showing any gastric or duodenal ulcer at least 3 mm in diameter with depth
- Screening laboratory alanine aminotransferase (ALT) or aspartate aminotransferase (AST) value > 2 times the upper limit of normal
- Estimated creatinine clearance < 30 ml/min
- Other than noted specifically, any screening laboratory value that was clinically significant in the investigator's opinion and would have endangered a subject if they were to have participated 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

Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Number of Participants With Gastric Ulcer Confirmed by Endoscopy
Time Frame: 6 months
|
The primary efficacy endpoint was the number of subjects with gastric ulcers at any time throughout 6 months of treatment.
An ulcer was defined as a mucosal break of at least 3 mm in diameter (measured by close application of open endoscopic biopsy forceps) with unequivocal crater depth.
A subject is considered to have completed the study if all scheduled assessments up through the 6 month visit have been performed or if the endpoint of gastric ulcer confirmed by endoscopy has been reached.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The Number of Participants With Pre-Specified NSAID-Associated Upper GI Adverse Events or Duodenal Ulcers
Time Frame: 6 months
|
The Number of Participants with Pre-Specified non-steroidal antiinflammatory drug (NSAID)-Associated Upper Gastrointestinal (UGI) Adverse Events or Duodenal Ulcers after 6 months of treatment.
Pre-specified UGI adverse events typically associated with NSAID use include dyspepsia, abdominal pain, gastritis, erosive esophagitis, duodenitis, abdominal discomfort

Improvement From Baseline in Upper Abdominal Pain and Discomfort Scores at 6 Months, Based on the Overall Treatment Evaluation for Dyspepsia Questionnaire
Time Frame: change from baseline at 6 Months
|
Improvement from baseline in Upper Abdominal Pain and Discomfort scores at 6 months, based on the overall Treatment Evaluation for Dyspepsia Questionnaire.
Subjects were asked: "since treatment started, has there been any change in your upper abdominal pain and/or discomfort?" Answers would be better/about the same/worse.
Participants with the response "better" (instead of "about the same" or "worse"), are tabulated by treatment group.

change from baseline at 6 Months
|
Mean Change From Baseline on Non-Pain Symptoms of the Severity of Dyspepsia Assessment (SODA) Subscales
Time Frame: baseline to 6 Months
|
Change from Baseline of Non-Pain Symptoms on the SODA Assessment.
There are 7 categories about the non-pain symptoms: burping/beching, heartburn, bloating, passing gas, sour taste, nausea and bad breath.
For each of these categories, subjects were to rate during the past seven days, on average, the severity on a 5 point scale ranging from no problem to very severe problem.
The scores are combined into a single composite score.
The total possible range of the non-pain symptoms subscale is: 7-35.

baseline to 6 Months
|
Mean Change From Baseline on Satisfaction of the Severity of Dyspepsia Assessment (SODA) Subscales
Time Frame: baseline to 6 Months
|
Mean Change in Satisfaction on SODA Assessment.
Questions/statements to rate about satisfaction/dissatisfaction with their present level of abdominal discomfort.
Question 1: 4-point scale range 0 (extremely unhappy) to 4 (extremely happy), statement 2 (I feel satisfied with my health with regard to abdominal discomfort) & statement 3 (I am pleased because my abdominal discomfort seems under control) on a 5 point scale (definitely true to definitely false) & question 4 rated how pleased subjects were with abdominal discomfort on a 10 point scale.
Total satisfaction composite range: 2-23

baseline to 6 Months
|
Mean Change From Baseline on Pain Intensity of the Severity of Dyspepsia Assessment (SODA) Subscales
Time Frame: baseline to 6 Months
|
Mean Change from Baseline on Pain Intensity of the Severity of Dyspepsia Assessment (SODA) Subscales.
There are 6 questions about abdominal pain during the past 7 days: q 1-5 on average: 1.
rate with a number between 0 (no pain) and 100 (pain as bad as it could be), 2. rate with a number between 0 (no discomfort) and 10 (discomfort as bad as it can be), 3. on a scale of 5 (from none to excriciating), 4. on 100 mm VAS, 5. on a scale of 4 and 6. worst abdominal pain scale 0 (no discomfort) and 10 (discomfort as bad as it can be).
Total composite possible range for "pain intensity" is: 2-47
