Brief Summary:
The purpose of this study is to study the safety and efficacy of high dose Prevacid in the long-term treatment of patients who secrete abnormally large amounts of gastric acid.

Condition or disease Intervention/treatment Phase
Zollinger-Ellison Syndrome Multiple Endocrine Neoplasia Drug: Lansoprazole (Prevacid) Phase 4

Detailed Description:
The aim of this protocol is to study the medical management of acid hypersecretory states including Zollinger-Ellison using Prevacid. The immediate objective is to heal peptic ulcers and eliminate symptoms and in the long term to prevent relapse of symptoms, lesions and complications. Other objectives include observation of the efficacy in controlling gastric acid production and of the safety of high dose, long-term use of Prevacid.

Actual Study Completion Date : December 2010

Arm Intervention/treatment
Experimental: single group
This is an open label, non-randomized, uncontrolled, single group study designed to treat patients with Zollinger-Ellison Syndrome and other hypersecretory conditions by controlling gastric acid production; to heal and prevent relapses of peptic ulcers and symptoms; to monitor the safety and efficacy of this treatment.
Drug: Lansoprazole (Prevacid)
Lansoprazole 30mg capsules. dose is individualized to each subject based on gastric acid production. The range is 30 mg to 450 mg daily.
Other Name: Lansoprazole is marketed as Prevacid.

Primary Outcome Measures :
  1. Long-term Medical(Non-surgical)Control of Gastric Acid Production Assessed From Time of Study Enrollment, up to 240 Months Post Enrollment. [ Time Frame: up to 240 months from study enrollment ]
    number of participants with control of gastric acid production

Secondary Outcome Measures :
  1. The Median Survival From the Time of Diagnosis. [ Time Frame: survival or up to 240 months ]
    The median survival from the time of diagnosis
