Sponsored by Trio Medicines Ltd. · Phase 2, Interventional, and Treatment
This study will evaluate whether treatment with YF476 is safe and effective in reducing the size of type II gastric carcinoid tumours, or limiting the abnormal growth of gastric ECL cells, in patients with Zollinger-Ellison syndrome.
152 studies on the registry are indexed under Carcinoid Tumor; 16 are open to participants now.
This study's enrollment of 3 is below the median of 36 across 106 interventional studies indexed under Carcinoid Tumor.

Exclusion criteria:
History or baseline findings of:
The dose will be 100 mg YF476 once daily. When 6 patients have completed 12 weeks' treatment with that dose, it may be increased to 150 or 200 mg once daily. Patients will have type II gastric carcinoids and/or ECL cell hyperplasia/dysplasia.
Drug: YF476
Gastrin receptor antagonist
Also known as: Netazepide
Regression of Gastric Carcinoids and/or ECL Cell Hyperplasia Defined by Physical Measurements Taken During Endoscopy
Regression is defined as a 25% reduction in the size / number of endoscopically evident type II gastric carcinoids. For each participant, three gastric carcinoids were identified and measured at baseline. The same gastric carcinoids were then measured at the Week 12 visit and the percentage difference in size from baseline calculated. The mean percentage change of the three gastric carcinoids per participant is recorded.
Time frame: Week 12 visit
A Reduction of 25% in the Gastric ECL Cell Density.
A reduction of 25% in the gastric ECL cell density.
Time frame: Week 12 visit
Improvement in Histological Grade of Gastric Carcinoids/ECL Cell Hyperplasia Defined by Physical Measurements Taken During Endoscopy
Reduction in the histological grade of the carcinoids/hyperplasia when compared to baseline.
Time frame: Week 12 visit
Level of Chromogranin A (CgA) Biomarkers Measured in Blood Samples
The level of a key biomarker chromogranin A (CgA) that is circulating in the blood was measured.
Time frame: Week 6 visit, Week 12 visit, Follow-up (12 weeks after stopping YF476 treatment)
Acid Control Study 1, Control of Gastric Acid Secretion Assessed by Changes in Drug-controlled Gastric Acid Analysis, Volume of Gastric Aspirate
Assessed by changes in drug-controlled gastric acid analysis. A nasogastric tube (NGT) was placed through one nare and into the stomach. Gastric secretions were suctioned and discarded at T = 0 and then aspirated for 1 h in 15 min increments to measure the control acid output. Patients who could not tolerate NGT placement had endoscopic gastric analysis (EGA) performed during upper endoscopy. During EGA, a single 10 - 15 min collection was aspirated under direct visualization. Patients 01 and 02 had acid measured via NGT, whereas Patient 03 had acid measured via EGA. At the Week 2 visit, the baseline acid control was measured. At the Week 6 visit, the acid control was measured after a dose of netazepide. Results are provided for three acid control measures: 1. Volume of aspirate (mL) 2. Acid in aspirate (mEq) 3. Acid output (mEq)
Time frame: Week 2 visit (baseline) and Week 6 visit
Decrease in ECL Cell-specific Products Assessed by Quantitative PCR
Assessed by quantitative PCR.
Time frame: Week 2 visit (baseline), Week 6 visit, Week 12 visit, Follow-up (12 weeks after stopping YF476 treatment)
Improvement in Reflux/Dyspepsia Symptoms Using the Gastroesophageal Reflux Disease Health Related Quality of Life (GERD-HRQL) Instrument
Assessed by the Gastroesophageal Reflux Disease Health Related Quality of Life (GERD-HRQL) instrument. Patients assessed a total of 10 symptoms on a scale of 0-5 where: 0 = no symptoms; 1 = symptoms noticeable, but not bothersome; 2 = symptoms noticeable and bothersome, but not every day; 3 = symptoms bothersome everyday; 4 = symptoms affect daily activities; and 5 = symptoms are incapacitating (unable to do daily activities). The total score was summed and reported. The maximum obtainable total score was 50 and minimum obtainable total score was 0, with higher scores indicating a worse outcome and lower scores indicating a better outcome.
Time frame: Week 2 visit (baseline), Week 6 visit, Week 12 visit, Follow-up (12 weeks after stopping YF476 treatment)
