Lead Sponsor:

VA Office of Research and Development

Conditions:

GERD

Eligibility:

All Genders

18-64 years

PHASE3

Brief Summary

Background: Gastroesophageal reflux disease (GERD), which affects at least 20% of adult Americans, may be especially common and severe in Veteran patients. Proton pump inhibitors (PPIs), which block g...

Eligibility Criteria

Inclusion

  • Age 18-70 years
  • History of heartburn (defined as a burning sensation in the retrosternal area of the chest) that is refractory to antisecretory medications
  • Initial GERD-HRQL:
  • Total score must be at least 6 and at least one of the six heartburn questions must be scored at least 2
  • GERD-HRQL after two weeks of treatment with omeprazole:
  • Total score must be \>50% of the initial GERD-HRQL score and at least one of the six heartburn questions must be scored at least 2
  • Either or both of the following by baseline esophageal pH/multichannel intraluminal impedance (MII) monitoring in patients on omeprazole 20 mg two times a day (BID):
  • Positive symptom association probability (SAP) (\>95%) for acid reflux, non-acid reflux or all reflux.
  • Abnormal acid reflux (esophageal pH\<4 for at least 4.2% of the 24-hour monitoring period)

Exclusion

  • Patients who do not have heartburn, defined as a burning sensation in the chest
  • Patients unwilling or unable to provide informed consent
  • Pregnancy or women unwilling to use effective contraception
  • Age \<18 or \>70 years

  • History of seizure disorder
  • History of heart block
  • Allergy to or previous inability to tolerate study medications (omeprazole, baclofen, desipramine)
  • Esophageal varices
  • Cirrhosis
  • Co-morbidity of sufficient severity to preclude elective surgery (e.g. pulmonary, cardiac, renal, liver disease)
  • History of disorders that can cause medically-refractory "GERD symptoms" (eosinophilic esophagitis, neoplasms of the upper gastrointestinal tract, gastroparesis, achalasia)
  • Myocardial infarction within the past 6 months
  • History of schizophrenia
  • Current use of clopidogrel
  • Patients who have a contraindication to omeprazole or baclofen or who require therapy with a medication that has a clinically important drug interaction with omeprazole or baclofen.
  • Patients who, in the judgment of the PI, are not suitable candidates for therapy with a study medication (omeprazole, baclofen, desipramine)
  • Initial GERD-HRQL score: Total score \<6 and/or all heartburn scores \<2
  • Inability to tolerate omeprazole during the 2-week treatment phase (before randomization)
  • GERD-HRQL after two weeks of treatment with omeprazole: Total score less than or equal to 50% of initial GERD-HRQL score and/or all heartburn scores \<2
  • Laboratory abnormalities including:
  • Platelet count \<100,000
  • international normalized ratio (INR) \>1.5 (off anticoagulants)
  • Serum creatinine \>2.0 mg per deciliter
  • Endoscopic abnormalities including:
  • Los Angeles Classification of Oesophagitis (LA grade) C or D reflux esophagitis
  • Active ulceration of the esophagus that is not due to reflux esophagitis
  • Candida esophagitis
  • Esophageal varices
  • Active ulceration of the stomach and/or duodenum
  • Neoplasm of the esophagus, stomach or duodenum
  • Gastric outlet obstruction
  • Eosinophilic esophagitis at least (15 eosinophils per high power field in any esophageal biopsy specimen)
  • Manometric abnormalities including:
  • Achalasia
  • Complete aperistalsis
  • Negative SAP ( 95%) for acid reflux, non-acid reflux and all reflux on baseline combined esophageal pH/MII monitoring and normal acid reflux (esophageal pH\<4 for \<4.2% of the 24-hour monitoring period)
  • Study surgeon identifies a contraindication to laparoscopic Nissen fundoplication
  • Morbid obesity (BMI at least 40)
  • Large paraesophageal hernia
