Domperidone Expanded Access Program for Oncology Patients With Gastroparesis Who Have Failed Standard Therapy

Study Overview
=================
Brief Summary
-----------------
Gastroparesis is a digestive disorder in which motility of the stomach is either slowed or absent. The gastroparesis prevents normal digestion from occurring. The purpose of this study is to provide oral Domperidone offered under the U.S. Food and Drug Administration (FDA) expanded access program, to patients that, based on the treating doctor's assessment, could benefit from , a prokinetic effect for the relief of refractory gastroesophageal reflux disease with upper gastrointestinal (GI) symptoms, gastroparesis, and chronic constipation.

Detailed Description
-----------------
At the discretion of the Investigator, 10-30 mg of oral domperidone is administered QID (four times a day). The Investigator will be starting patients on 10 mg four times a day for 2 weeks, then increase to 20 mg four times a day for 2 weeks. The participant will be evaluated at each time point. If the participant still is not having relief of symptoms the investigator may increase their dose to 30mg four times a day.
