Published Studies Related to Prevacid I.V. (Lansoprazole)
A multicenter, randomized, comparative study to determine the appropriate dose of lansoprazole for use in the diagnostic test for gastroesophageal reflux disease. [2011.09]
BACKGROUND/AIMS: The diagnostic proton pump inhibitor test (PPI test) is a method used in diagnosing gastroesophageal reflux disease (GERD). This study aimed to determine the appropriate dose of lansoprazole for use in the diagnostic test for GERD... CONCLUSIONS: In this multicenter, randomized study of Korean patients, the standard dose of lansoprazole was as effective as a high dose of lansoprazole in relieving the symptoms of GERD, regardless of the presence of ERD, by day 14 of treatment.
Preventive effects of lansoprazole and famotidine on gastric mucosal injury induced by low-dose aspirin in Helicobacter pylori-negative healthy volunteers. [2011.07]
The preventive effects of lansoprazole and famotidine on low-dose aspirin-induced gastric mucosal injury in relation to gastric acidity were compared in healthy Japanese volunteers. Fifteen Helicobacter pylori-negative volunteers with different CYP2C19 genotypes were randomly administered aspirin 100 mg, aspirin plus famotidine 20 mg twice daily, or aspirin plus lansoprazole 15 mg once daily for 7 days each in a crossover fashion.
Lansoprazole for secondary prevention of gastric or duodenal ulcers associated with long-term low-dose aspirin therapy: results of a prospective, multicenter, double-blind, randomized, double-dummy, active-controlled trial. [2011.06]
BACKGROUND: The efficacy of low-dose lansoprazole has not been established for the prevention of recurrent gastric or duodenal ulcers in those receiving long-term low-dose aspirin (LDA) for cardiovascular and cerebrovascular protection. This study sought to examine the efficacy of low-dose lansoprazole (15 mg once daily) for the secondary prevention of LDA-associated gastric or duodenal ulcers... CONCLUSION: Lansoprazole was superior to gefarnate in reducing the risk of gastric or duodenal ulcer recurrence in patients with a definite history of gastric or duodenal ulcers who required long-term LDA therapy.
The effect of dexlansoprazole MR on nocturnal heartburn and GERD-related sleep disturbances in patients with symptomatic GERD. [2011.03]
OBJECTIVES: Nocturnal heartburn and related sleep disturbances are common among patients with gastroesophageal reflux disease (GERD). This study evaluated the efficacy of dexlansoprazole MR 30 mg in relieving nocturnal heartburn and GERD-related sleep disturbances, improving work productivity, and decreasing nocturnal symptom severity in patients with symptomatic GERD... CONCLUSIONS: In patients with symptomatic GERD, dexlansoprazole MR 30 mg is significantly more efficacious than placebo in providing relief from nocturnal heartburn, in reducing GERD-related sleep disturbances and the consequent impairments in work productivity, and in improving sleep quality/quality of life.
The 12-month safety profile of dexlansoprazole, a proton pump inhibitor with a dual delayed release formulation, in patients with gastro-oesophageal reflux disease. [2011.02]
BACKGROUND: Dexlansoprazole MR is a Dual Delayed Release formulation of dexlansoprazole, an enantiomer of lansoprazole, designed to extend the duration of acid suppression. AIM: To assess the 12-month safety of dexlansoprazole MR in patients with symptomatic gastro-oesophageal reflux disease (GERD)... CONCLUSIONS: Twelve-month treatment with dexlansoprazole MR 60 and 90 mg was well tolerated by GERD patients in this study (Clinicaltrials.gov identifier NCT00255190).

Clinical Trials Related to Prevacid I.V. (Lansoprazole)
Intravenous vs Oral Lansoprazole on Gastric Acid Secretion in Subjects With Erosive Esophagitis [Completed]
The objective of this study was to compare the pharmacodynamics of intravenous (IV)
lansoprazole 30 mg to oral lansoprazole 30 mg capsules in subjects with erosive esophagitis.
Study Comparing Esomeprazole Magnesium 40mg Once Daily Versus Lansoprazole 30 mg Twice Daily in Symptom Control of Subjects With Persistent GERD [Completed]
A double-blind study comparing Esomeprazole Magnesium 40 mg once daily and Lansoprazole 30 mg
twice daily to control the symptoms in patients with gastroesophageal reflux disease (GERD)
with continued heartburn symptoms with a course of therapy of 30 mg twice daily
Lansoprazole.
Efficacy/Safety of Lansoprazole in Patients With Frequent Nighttime Heartburn [Completed]
Heartburn, a burning sensation in the chest or throat, occurs in many individuals when acidic
stomach contents move upward into the esophagus from the stomach. This study will
investigate the safety and efficacy of lansoprazole 15 mg or 30 mg administered once a day in
preventing frequent nighttime heartburn.
The Insulin Independence Trial (IIT) Evaluating the Safety and Efficacy of Oral Cyclosporine and Oral Lansoprazole for Insulin Independence Among Patients With Existing Type 1 Diabetes [Not yet recruiting]
The purpose of this study is to determine if oral cyclosporine and oral lansoprazole are
effective in rendering patients with existing type 1 diabetes, insulin independent. This
four-arm study was designed to evaluate the safety and efficacy for insulin independence by
utilizing the FDA-approved oral immune tolerance agent, cyclosporine, and the FDA-approved
proton-pump inhibitor, lansoprazole. Lansoprazole and other proton-pump inhibitors increase
gastrin levels. Gastrin was initially shown to have the potential to increase new beta cell
formation in 1955 (Zollinger RM and Ellison EH. Ann Surg. 1955;142(4):709-23).
Studies with the immune tolerance agent, cyclosporine, previously demonstrated that among
recently diagnosed type 1 diabetes patients, insulin independence was achieved in as many as
67. 5% of patients within 7 weeks of therapy (Bougneres PF et al. N Engl J Med.
1988: 17;318(11):663-70). Cyclosporine protected the remaining beta cells from further
autoimmune attack, but over time, there was limited beta cell regeneration, and insulin was
ultimately required by all patients. Therefore, this study proposes the usage of
cyclosporine with a beta regeneration agent.
Follow-up studies for up to 13 years among 285 type 1 patients utilizing cyclosporine for 20
months, did not demonstrate renal or other side effects (Assan R. et al. Diabetes Metab Res
Rev. 2002;18(6):464-72). Human clinical trials with gastrin and epidermal growth factor
demonstrated reductions in daily insulin requirements by much as 75% within 3 months
following four weeks of therapy among existing type 1 diabetes patients (Transition
Therapeutics, March 5, 2007 http://www. transitiontherapeutics. com/media/archive. php Accessed
January 1, 2013). Lack of the ability to sustain these results was likely due to the ongoing
autoimmune attack on the new beta cells generated by therapy. Gastrin alone has been shown
to induce beta cell neogenesis from human pancreatic ductal tissue without epidermal growth
factor in in vitro studies (Suarez-Pinzon WL et al. JCEM. 2005;90(6):3401-3409).
Type 1 diabetes is an autoimmune disease. Despite evidence that many different immune
tolerance agents have successfully reversed diabetes in rodent type 1 models, none have been
successful in sustaining insulin independence in man (Ablamunits V et al. Ann NY Acad Sci.
2007;1103: 19-32). The distinctions and complexities of islets in man are far different than
that of rodents (Levetan CS and Pierce SM. Endocr Pract. 2012 Nov 27: 1-36 Epub ahead of
print). We hypothesize that in man, both an immune tolerance agent and a beta regeneration
agent are required to sustain insulin independence.
Based upon proton-pump inhibitors having been shown to increase plasma gastrin levels up to
10-fold, this clinical trial utilizes the oral proton-pump inhibitor, lansoprazole. This
study will determine the safety and efficacy of cyclosporine used with and without
lansoprazole to determine the impact on insulin independence among patients with existing
type 1 diabetes.
Cyclosporine is utilized to protect the new beta cells formed by lansoprazole. The
combination of the two therapies may render reductions in insulin requirements and have a
greater impact on sustained insulin independence than previously reported with cyclosporine
or gastrin alone among type 1 patients.
This 12-week study consists of four treatment arms:
- Oral Cyclosporine/Placebo
- Oral Lansoprazole/Placebo
- Oral Lansoprazole/Oral Cyclosporine
- Oral Placebo/Oral Placebo
It is hypothesized that the combination of oral cyclosporine and oral lansoprazole will
safely render significantly more patients with existing type 1 diabetes, insulin independent
and may serve as a novel and innovative treatment approach for patients with type 1 diabetes
utilizing two FDA-approved therapies.
