Eligibility

Inclusion criteria

Inclusion criteria: Patients are eligible to participate in this study if all of the following criteria are met: 1. Presence of clinical symptoms associated with idiopathic gastroparesis; nausea, vomiting, early satiety, postprandial fullness and a GCSI score ≥ 1 at Visit 1b (eligibility; week -1); 2. Delayed gastric emptying for solids at Visit 1b (eligibility; week -1) as measured with scintigraphy: a. 2h retention ≥ 60%; b. 4h retention ≥ 10%; 3. Absence of an obstructing structural lesion in the stomach or small intestine at prior diagnostic gastrointestinal endoscopy (performed within the previous 5 years) or judged absent by the responsible physician; 4. Patients, both male and female, must use adequate means of birth control during the study; 5. Patients must provide written informed consent prior to any study procedures being performed; 6. Patients aged between 18 and 70 years inclusive; 7. Patients (in the opinion of the investigator) must be able to understand the study and comply with the study requirements.

Exclusion criteria

Exclusion criteria: Patients are excluded from the study if any of the following criteria are met: 1. Patients with predominant abdominal pain/discomfort in the opinion of the investigator; 2. Presence of an obstructing structural lesion in the stomach or small intestine if observed during treatment gastrointestinal endoscopy (visit 2, randomization; week 0); 3. Patients taking drugs that interfere with the effect of botulinum toxin type A; 4. Patients previously treated with intrapyloric injection of botulinum toxin type A; 5. Females who are pregnant or lactating; 6. Patients with diabetes mellitus; 7. Patients with delayed gastric emptying due to systemic disorders, e.g. SLE, sclerodermia, hypothyroidism; 8. Patients with disorders of neuromuscular transmission, e.g. myasthenia gravis and Eaton-Lambert syndrome; 9. Patients with abdominal surgery in their medical history, except (laparoscopic) appendectomy, (laparoscopic) cholecystectomy and/or hysterectomy; 10. Patients with any condition which, in the opinion of the investigator, makes the patient unsuitable for entry into the study.

Design outcomes

Primary

MeasureTime frame
Gastric emptying for solids. 1. Half-emptying time at visit 4 (follow-up; week 6) compared to Visit 1b (eligibility; week -1); 2. Emptying rate per hour at visit 4 (follow-up; week 6) compared to Visit 1b (eligibility; week -1); 3. One, two and four hour meal retention at visit 4 (follow-up; week 6) compared to Visit 1b (eligibility; week -1). Gastroparesis Cardinal Symptom Index (GCSI) outcome; 4. Total GCSI score at visit 3, 4, 5 and 6 (follow-up; week 3, 6, 9 and 12) compared to visit 2 (randomization; week 0); 5. Mean GCSI score during follow-up (week 0-12) compared to mean GCSI score during eligibility and randomization (week -1-0).

Secondary

MeasureTime frame
1. Gastric emptying for liquids; retention of liquid phase at 15, 30, 45, 60, 75, 90, 105 and 120 min; 2. Quality of Life as measured with the Patient Assessment of Upper Gastrointestinal Disorders - Quality of Life (PAGI-QoL), the RAND-36 and EQ-5D questionnaires; 3. Psychometric assessment and patient perception of gastrointestinal endoscopy.
