Efficacy and Safety of a 0.1% Tacrolimus Nasal Ointment as a Treatment for Epistaxis in Hereditary Hemorrhagic Telangiectasia: A Double-Blind, Randomized, Placebo-Controlled, Multicenter Trial.

ABSTRACT: Hereditary hemorrhagic telangiectasia is a rare but ubiquitous genetic disease. Epistaxis is the most frequent and life-threatening manifestation and tacrolimus, an immunosuppressive agent, appears to be an interesting new treatment option because of its anti-angiogenic properties. Our objective was to evaluate, six weeks after the end of the treatment, the efficacy on the duration of nosebleeds of tacrolimus nasal ointment, administered for six weeks to patients with hereditary hemorrhagic telangiectasia complicated by nosebleeds, and we performed a prospective, multicenter, randomized, placebo-controlled, double-blinded, ratio 1:1 phase II study. Patients were recruited from three French Hereditary Hemorrhagic Telangiectasia (HHT) centers between May 2017 and August 2018, with a six-week follow-up, and we included people aged over 18 years, diagnosed with hereditary hemorrhagic telangiectasia and epistaxis (total duration > 30 min/6 weeks prior to inclusion). Tacrolimus ointment 0.1% was self-administered by the patients twice daily. About 0.1 g of product was to be administered in each nostril with a cotton swab. A total of 50 patients was randomized and treated. Mean epistaxis duration before and after treatment in the tacrolimus group were 324.64 and 249.14 min, respectively, and in the placebo group 224.69 and 188.14 min, respectively. Epistaxis duration improved in both groups, with no significant difference in our main objective comparing epistaxis before and after treatment (p = 0.77); however, there was a significant difference in evolution when comparing epistaxis before and during treatment (p = 0.04). Toxicity was low and no severe adverse events were reported. In conclusion, tacrolimus nasal ointment, administered for six weeks, did not improve epistaxis in HHT patients after the end of the treatment. However, the good tolerance, associated with a significant improvement in epistaxis duration during treatment, encouraged us to perform a phase 3 trial on a larger patient population with a main outcome of epistaxis duration during treatment and a longer treatment time.

Project description:ImportanceEpistaxis is the greatest cause of morbidity in patients with hereditary hemorrhagic telangiectasia (HHT); because of this, a validated epistaxis-specific quality-of-life instrument for HHT should be made available.ObjectiveTo develop and validate an epistaxis-specific quality-of-life patient-reported outcome measure for HHT.Design, setting, and participantsThis survey study focused on the development and validation of the Nasal Outcome Score for Epistaxis (NOSE) in HTT (NOSE HHT) outcome measure with data prospectively collected from December 10, 2019, to March 15, 2020. A total of 401 patients were recruited from within the Cure Hemorrhagic Telangiectasia online patient advocacy social media network, the Washington University HHT Center of Excellence, and a randomized clinical trial investigating an intranasal timolol gel for HHT-associated epistaxis.Main outcomes and measuresFace and content validity, factor analysis, internal consistency as measured through Cronbach α, construct validity, responsiveness to change, and minimal clinically important difference.ResultsThe NOSE HHT was developed and validated with a possible score ranging discretely from 0 to 4 for each of the 29 items and a total score ranging continuously from 0 to 4 after dividing by the total number of items answered. A total of 401 participants completed the NOSE HHT. Factor analysis identified 3 factors that matched the a priori specified subgroups of particular aspects of life affected by HHT-associated epistaxis: physical problems (mean [SD] magnitude, 1.59 [0.83]), functional limitations (mean [SD] magnitude, 1.28 [0.84]), and emotional consequences (mean [SD] magnitude, 1.95 [1.02]). The instrument had high internal consistency with an overall Cronbach α of 0.960. Convergent validity determined the total NOSE HHT score to be a strong predictor of disease severity; total NOSE HHT score can be split up into the following epistaxis severity categories: mild (0-1), moderate (1.01-2), and severe (>2). The instrument was found to be sensitive to change, and the minimal clinically important difference for the total NOSE HHT score was 0.46.Conclusions and relevanceEvaluation of the consistency, reliability, and responsiveness of the NOSE HHT survey found it to be a valid instrument to assess severity and change in epistaxis. Study results suggest that the NOSE HHT survey is clinically applicable and useful as an outcome measure of future HHT-associated epistaxis trials.

Project description:Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disorder characterized by the presence of telangiectasias and arteriovenous malformations in various organs and organ systems, including the liver. The most frequent clinical manifestation of HHT is epistaxis.In 2010 (January-December inclusive) 51 patients with HHT were admitted to the ENT ward of our hospital for epistaxis, and in accordance with routine protocols, all 51 underwent abdominal ultrasonography in our department to detect hepatovascular lesions. They included 27 males (53%) and 24 (47%) females ranging in age from 11 to 86 years (mean 48.5 years). The sample was selected in an arbitrary manner to take maximum advantage of the hospital stay and monitor patients from regions other than our own.Retrospective analysis of the findings from these sonographic examinations revealed hepatic HHT in 27 (53%) of the 51 patients. Nineteen (70%) of these (age range 40-86 years, mean 63) had vascular malformations of various dimensions but no portal hypertension; the other eight (30%) (age range 39-81 years, mean 60) had vascular malformations plus portal hypertension.Our retrospective analysis indicates that a significant number of patients can have unrecognized hepatic involvement; that the appearance of hepatic lesions can be fairly unpredictable, even when the HHT has been diagnosed for years and the patients are already symptomatic; and that the hepatic lesions are frequently progressive. Therefore, regular sonographic follow-up is advisable for patients with HHT.The limitations of this study are related to the small number of patients examined and to the fact that all of them were symptomatic. Further study is therefore needed (especially in asymptomatic patients) to define the indications for hepatic sonography and the optimum examination schedule.Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disorder characterized by the presence of telangiectasias and arteriovenous malformations in various organs and organ systems, including the liver.
