Brief summary
In a case series intranasal submucosal bevacizumab has been shown to reduce epistaxis in patients suffering from Hereditary Haemorrhagic Telangiectasia together with KTP Laser therapy. The aim of this study is to evaluate the effectiveness of submucosal intranasal bevacizumab compared to placebo in a randomized double blind trial setting.
Interventions
100mg intranasal submucosal bevacizumab in 10ml
10ml of 0.9% NaCl intranasal submucosal

Inclusion criteria
* Diagnosed and staged HHT (Shovlin et al 2000) * Age 18-80 * Minimum of 2 episodes of epistaxis/ week * Ability and willingness to complete diary and comply with study requirements.
Exclusion criteria
* Uncontrolled hypertension (systolic blood pressure \> 150mmHg, diastolic blood pressure \> 90mmHg) * History of a thromboembolic event, including myocardial infarction or cerebral vascular accident * Malignancy of the upper respiratory tract within the last year * Recent (\<3 months) or planned surgery * Proteinuria * Nasal intervention (Laser or Cautery) in pretreatment phase * Allergy to local anesthetic
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| relative change in average daily Epistaxis VAS scores compared to baseline | day 10 - 84 posttreatment | Daily epistaxis VAS scores are recorded in a diary. The baseline score is the average daily epistaxis VAS score 4 weeks before treatment (day -28 to 0). This score is compared to the average daily VAS score day 10-84 posttreatment. The relative change of this average score compared to baseline is the primary outcome. |
Secondary
| Measure | Time frame |
|---|---|
| Epistaxis frequency, duration and severity compared to baseline | day 10 - 84 posttreatment |
| Number of emergency department visits due to epistaxis compared to baseline | day 10 - 84 posttreatment |
| Epistaxis Severity Score HHT-ESS compared to baseline | 3 months post treatment |
| Number of transfusions needed compared to baseline | day 10-84 posttreatment |
| Average daily epistaxis VAS scores compared to baseline among age groups and among groups with different epistaxis severity | day 10-84 posttreatment |
| lab results (ferritin values, Hb, Hct) compared to baseline | day 84 posttreatment |
