E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Patients with Rendu-Osler-Weber disease (which is also called: Hereditary hemorrhagic telangiectasia) |
|
E.1.1.1 | Medical condition in easily understood language |
Patients with Rendu-Osler-Weber disease (which is also called: Hereditary hemorrhagic telangiectasia. |
|
E.1.1.2 | Therapeutic area | Diseases [C] - Digestive System Diseases [C06] |
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to assess the efficacy of octreotide LAR in decreasing the need for transfusions and endoscopic intervention in patients ROW with refractory anaemia due to gastrointestinal bleeding telangiectasias. |
|
E.2.2 | Secondary objectives of the trial |
• Does octreotide LAR reduce the number of rebleeds and thereby increases the haemoglobin level?
A bleeding episode is defined as:
Overt bleeding: melaena or hematochezia
or
Occult bleeding: iron deficiency anaemia and a hematocrit of <30% for >6 months
• The third objective is to assess safety of octreotide LAR in a dosage of 20 mg per 4 weeks in ROW patients.
• Fourth, does octreotide LAR decrease the epistaxis episodes in ROW patients?
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Patients with Rendu-Osler-Weber
- Symptomatic gastrointestinal bleeds out of telangiectasias
- Transfusion and / or endoscopy dependent:
Transfusion: at least 2 blood and/or iron infusions in the 6 months before inclusion.
Endoscopy: at least one endoscopy with APC after the initial endoscopic treatment after diagnosis in the half year before inclusion or unsuitable for endoscopy.
|
|
E.4 | Principal exclusion criteria |
- liver cirrhosis Child-Pugh C or acute liver failure
- previous unsuccessful treatment with somatostatin analogues for the same indication (refractory anaemia due to telangiectasias) or current effective treatment with a somatostatin analogue
- current successful treatment with thalidomide
- severe diseases with life expectancy < 1 year
- patients with left ventricular assist devices (LVAD’s)
- Symptomatic cholecystolithiasis (without cholecystectomie)

- systemic cancer currently undergoing chemotherapy or radiation therapy
- no understanding of Dutch or English

E.5 End points |
E.5.1 | Primary end point(s) |
Primary outcome is response to treatment defined as:
- complete: no endoscopic intervention or transfusion requirements
- partial: a reduction in endoscopic intervention or transfusion requirements
- non-response: an equal or increase in endoscopy frequency or transfusions
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |

The percentual decrease in the number of endoscopic interventions between the 6 months prior to inclusion and the treatment period of 6 months.
The mean/median decrease on the epistaxis severity score (ESS) between baseline and the end of treatment visit (ET).
Percentage of hemoglobin increase from baseline until end of treatment.
The mean difference in hemoglobin level from baseline until end of treatment.
The change in number and severity of GI bleeding episodes (see for definition section 4.3.2) the 6 months prior to inclusion and the treatment period of 6 months.
The percentual decrease in number of patients free of rebleeding between start and end of treatment.
Reduction in oral iron requirement between start and end of treatment (see for definition section 4.3.3 “standard of care”)
The number and type of adverse events (cardiac, pulmonary, neurological, other)
Difference in number of hospitalizations, ICU admissions and duration of hospitalization between the 6 months prior to inclusion and the treatment period of 6 months.
Change in quality of life using the SF-36 questionnaire between baseline and end of treatment visit. |
