Conditions

Gastrointestinal bleeding and epistaxis caused by hereditary hemorrhagic telangiectasia. Hereditary Hemorrhagic Telangiectasia (HHT) is an autosomal dominant inherited disease characterized by mucocutaneous telangiectasis. Telangiectasis predominantly observed in the nasal mucosa and gut, and are abnormal, thin walled blood vessel that can easily rupture leading to hemorrhage. MedDRA version: 20.0 Level: LLT Classification code 10038554

Design outcomes

Primary

MeasureTime frame
Main Objective: To assess the efficacy and safety of oral tacrolimus in reducing bleeding severity in HHT patients with severe epistaxis and/or gastrointestinal bleeding. The primary objective is to measure the hemoglobin level at the beginning and during the trial.;Secondary Objective: As secondary outcomes, reduction in the epistaxis severity score (ESS), quality of life, the safety (side-effects, (s)AEs) of the therapy, and difference in monthly epistaxis duration, epistaxis frequency, the use of iron infusions, blood transfusions, mean ferritin will be evaluated after 20 weeks of therapy compared to the parameters at baseline. ;Primary end point(s): The primary outcome of this study is the difference in hemoglobin levels at the baseline compared to that at the end of the trial;Timepoint(s) of evaluation of this end point: The primary end point will be evaluated at the baseline and at the end of the trial. The difference will be calculated

Secondary

MeasureTime frame
Secondary end point(s): • Difference in monthly epistaxis severity measured with: o Epistaxis severity score (ESS); o Monthly number of episodes; o Monthly duration; o Monthly intensity; o VAS score of epistaxis. • Difference in biochemical blood values: Hb and ferritin. • Differences in required number of blood transfusions and iron infusions. • Difference in quality of life with SF-36 and fatigue complaints (MFI-20) between baseline and end of the study. ;Timepoint(s) of evaluation of this end point: All the secondary end points will be evaluated at the baseline and at the end of the trial. The only exception is the difference in required number of blood transfusions and iron infusions. We will compare the number of required number of blood transfusions and iron infusions during the trial (20 weeks) and to the same period prior to the trial
