Eligibility Criteria
Inclusion
- Histologically confirmed well-differentiated (grade 1 or grade 2) neuroendocrine tumour from small bowel primary (or unknown primary suspected to be of small bowel origin) as per WHO / ENETS classification
- Advanced disease (locally advanced, metastatic or recurrent, according to TNM staging version 8 or ENETS latest classification), not amenable for curative surgery
- No previous systemic treatment for the advanced neuroendocrine tumour (including somatostatin analogue)
- Highly functioning carcinoid syndrome, defined as:
- Mean ≥4 bowel movements per day; patients will have a one-week run-in screening period for recording of frequency and consistency of diarrhea (Only those who complete the one-week run-in screening period and are ≥6 days out of 7 compliant with diary entries will be considered eligible and randomized).
- And
- \- Serum, plasma or urine 5-HIAA levels ≥2 ULN (within 28 days of study entry)
- Age ≥18 years (no upper limit) and life expectancy \>3 months
- Adequate haematological, hepatic and renal laboratory values:
- Neutrophils \>1500 cells/mm3
- Platelets \>75,000 cells/mm3
- Hemoglobin (Hgb) \>9 g/dL for males and \>8 g/dL for females
- Aspartate transaminase (AST) and alanine aminotransferase (ALT): \<2.5 x upper limit of normal (ULN) if patient does not have documented history of hepatic metastases or \<5.5 x ULN if patient has documented history of hepatic metastases
- Total bilirubin ≤1.5 x ULN (unless patient has a documented history of Gilbert's Syndrome)
- Alkaline phosphatase (ALP) \<5 x ULN, if total bilirubin is \>ULN
- Serum creatinine \<1.5 x ULN and with creatinine clearance \> 30 ml/min as calculated with MDRD Formula
- Women of child bearing potential (WOCBP) MUST have a negative serum pregnancy test within 3 days prior to the first dose of study treatment.
- Unless child bearing potential has been terminated by surgery / radical radiotherapy, women of childbearing / reproductive potential should use highly effective birth control measures, during the study treatment period and for at least 30 days after the last study treatment and then according to the investigator recommendation or national/institutional guideline. A highly effective method of birth control is defined as those which result in low failure rate (i.e. less than 1% per year) when used consistently and correctly.
- Female subjects who are breast feeding should discontinue nursing prior to the first dose of study treatment and until 5 months months after the last study treatment.
- Before patient registration/randomization, written informed consent must be given according to ICH/GCP, and national/local regulations.
Exclusion
- Patients who are planned to be treated with other anti-tumour treatment (e.g. chemotherapy, liver embolization, Peptide Receptor Radionuclide Therapy (PRRT)) at the time of the study entry.
- Major surgery defined as procedures requiring general anesthesia or major regional anesthesia within 8 weeks prior to registration.
- Administration of any investigational therapeutic agent prior to registration (investigational imaging tracers are allowed).
- Patients who received any previous systemic treatment for carcinoid syndrome or tumour control (including SSA); previous use of anti-diarrheal medication such as loperamide or codeine is allowed.
- Patient with diarrhea and/or flushing due to any cause other than the neuroendocrine tumour such as fat malabsorption, bile acid malabsorption, enteric pathogens (parasites or clostridium difficile), short bowel syndrome (SBS) or malignancy.
- Allergy / history of hypersensitivity reaction to any of the treatment components.
- Any evidence of severe or uncontrolled systemic disease which, in the view of the investigator, makes it undesirable for the patient to participate in the trial.
- Patients with end-stage renal disease requiring dialysis.
- Patients with severe hepatic impairment (Child-Pugh score C).
- Patients with known rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption.
- Any patient with a medical or psychiatric condition that impairs their ability to give informed consent.
- Any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial.
- Inclusion/Exclusion Criteria for long-term follow-up for carcinoid heart disease (assessed locally)
- Patients diagnosed with carcinoid heart disease during the baseline or 12-month treatment period will be eligible
- Patients with suspected carcinoid heart disease but with poor/limited transthoracic echocardiogram windows, will not be eligible for long-term carcinoid heart disease follow-up
- Patients with moderate/severe valvular heart disease secondary to any pathology other than carcinoid heart disease (as classified by the ESC valvular heart disease guidelines10) are not eligible
- Patients with any pre-existing right sided heart disease such as arrythmogenic ventricular cardiomyopathy and patients with pre-existing atrial or ventricular arrythmia are not eligible
- Patients with pre-existing cardiomyopathy (such as hypertrophic cardiomyopathy or dilated cardiomyopathy) are not eligible
- Patients with implanted cardiac devices (i.e. pacemakers or an implantable cardioverter defibrillator) are not eligible
