Treatment of IPF With Laparoscopic Anti-Reflux Surgery (WRAP-IPF)

This study is ongoing, but not recruiting participants.
National Heart, Lung, and Blood Institute (NHLBI)
Information provided by (Responsible Party):
University of California, San Francisco Identifier:
First received: November 6, 2013
Last updated: October 24, 2016
Last verified: October 2016
This study will test the hypothesis that treatment with laparoscopic anti-reflux surgery in subjects with idiopathic pulmonary fibrosis (IPF) and abnormal gastroesophageal reflux (GER) will slow the decline of forced vital capacity (FVC) over 48 weeks.

Condition Intervention Phase
Idiopathic Pulmonary Fibrosis Gastroesophageal Reflux Procedure: Surgery Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Weighing Risks and Benefits of Laparoscopic Anti-Reflux Surgery in Patients With Idiopathic Pulmonary Fibrosis
