Outcome Measures

Primary Outcomes (1)

  • Achievement of Sustained Difference in Inhibition of Intragastric Acidity Based on Median pH Values Between the Two Active Study Treatments at Steady-state on Day 7

    Median intragastric pH scores were collected at 5 minute intervals after treatment dose. The achievement of sustained difference was the earliest time for which a statistically significant difference was observed in the median intragastric pH scores for 3 consecutive 5-minute intervals. The earliest 3 time points for which a statistically significant difference was observed between the median intragastric pH values for the two active treatments for three consecutive 5-minute intervals are shown here.

    Treatment dose to 4-hr post-dose on Day 7

Secondary Outcomes (17)

  • Achievement of Sustained Difference in Inhibition of Intragastric Acidity Based on Median pH Values Between the Two Active Study Treatments at Steady-state on Day 1

    Treatment dose to 4-hr post-dose on Day 1

  • The Difference in the Onset of Action Based on Median pH Values Between the Two Active Treatments Compared to No Treatment on Day 1 and Day 7

    Treatment dose to 4-hr post-dose on Day 1 and Day 7

  • Median Time to Achieve Intragastric pH > = 3.5 for a 10-Minute Period

    Treatment dose to 4-hr post-dose on Day 1 and Day 7

  • Percentage Time Intragastric pH >4 During the First 4 Hours After Dosing on Day 7

    Treatment dose to 4 hours Post-dose on Day 7

  • Median 24-hr Intragastric pH on Day 7

    Treatment dose to 24-hour post-dose on Day 7

  • +12 more secondary outcomes

Study Arms (3)

Zegerid

EXPERIMENTAL

Participants receiving Zegerid (omeprazole/sodium bicarbonate) in Periods 1, 2 or 3. All participants were randomized to a 3-way crossover design and received Zegerid Capsules (20 mg omeprazole/ 1100 mg sodium bicarbonate), Prevacid Capsules (15 mg lansoprazole), or no treatment in a random order. All participants also took approximately 2 oz of water with their medication.

Drug: Zegerid

Prevacid®

ACTIVE COMPARATOR

Participants receiving Prevacid® (lansoprazole) in Periods 1, 2 or 3. All participants were randomized to a 3-way crossover design and received Zegerid Capsules (20 mg omeprazole/ 1100 mg sodium bicarbonate), Prevacid Capsules (15 mg lansoprazole), or no treatment in a random order. All participants also took approximately 2 oz of water with their medication.

Drug: Prevacid®

No treatment

NO INTERVENTION

Participants receiving No treatment in Periods 1, 2 or 3. All participants were randomized to a 3-way crossover design and received Zegerid Capsules (20 mg omeprazole/ 1100 mg sodium bicarbonate), Prevacid Capsules (15 mg lansoprazole), or no treatment in a random order. All participants took approximately 2 oz of water once daily for 7 days.

Interventions

  • Positive H. pylori breath test at screening.
  • Participation in any study of an investigational treatment in the 30 days before Screening or participation in another study at any time during the period of this study
  • Any significant medical illness that would contraindicate participation in the study
  • Gastrointestinal disorder or surgery leading to impaired drug absorption
  • Any significant mental illness, such as schizophrenia or bipolar disorder
  • History (in the past year) suggestive of alcohol or drug abuse or dependence, or excessive alcohol use (\>2 units per day on average; for example \>2 bottles of beer, \>2 glasses of wine, \>2 ounces of liquor/spirits), or excessive alcohol use during the study
  • Any abnormal Screening laboratory value that is clinically significant in the investigator's opinion
  • Currently using or use of any prescription or over the counter (OTC) medications that affect gastrointestinal function, including first generation antihistamines (e.g. diphenhydramine) and anticholinergic agents within 7 days prior to 1st treatment administration.
  • Currently using, or use within 14 days of first treatment administration, or having a history of frequent use of antacids, OTC or Prescription (Rx) H2 receptor antagonists, or OTC or Rx use of proton pump inhibitors.
  • Positive urine drug/alcohol test at Screening.
