Active clinical trials for "Epistaxis"

Antiangiogenic drugs, such as bevacizumab, are a new treatment strategy in Hereditary Hemorrhagic Telangiectasia (HHT). Its systemic administration in patients with HHT improves liver damage-related symptoms and epistaxis (cases reported and on-going study-ClinicalTrials.gov Identifier #NCT00843440-). To limit the systemic adverse effects of bevacizumab and to ease administration, a local administration seems suitable. A clinical case recently showed the benefits of bevacizumab nasal spray in these patients. Its results were confirmed in a characterization study on bevacizumab transport through porcine nasal mucosa (in press). It seems necessary to assess the tolerance and efficacy of bevacizumab nasal spray in humans for the treatment of epistaxis in HHT with a prospective phase 1 study. The primary objective of the study is to evaluate the tolerance of increasing doses of bevacizumab administered as a nasal spray in patients with HHT-related epistaxis. This phase-1, randomized, double-blind, placebo-controlled, monocentric study is to be carried out sequentially (dose escalation) on 5 groups of 8 patients. Each group is made up of 6 verum and 2 placebos.

The purpose of this study is to test a novel and tolerable office-based treatment method, sclerotherapy with sodium tetradecyl sulfate, for recurrent epistaxis (nosebleeds) related to Hereditary Hemorrhagic Telangiectasia (HHT) disease.

Hereditary Hemorrhagic Telangiectasia (HHT) is a genetic disorder of angiogenesis associated with disabling epistaxis. Management of these nose bleedings requires more effective treatment. Propranolol, a beta-blocker, is a potentially useful therapeutic considering its anti-angiogenic properties. Our objective is to explore the efficacy of propranolol, three months after its introduction, on the cumulative duration of epistaxis in HHT patients.

This study is a double-blinded, randomized controlled trial to evaluate the efficacy of an intranasal topical timolol gel in the care for epistaxis in adults with hereditary hemorrhagic telangiectasia.

Timolol is a nonselective β-blocker commonly used in the treatment of glaucoma. Recently it has been used topically for the treatment of superficial hemangiomas. Because of its potential mechanism of action, it is possible that timolol could also be useful for the treatment of epistaxis in Hereditary Hemorrhagic Telangiectasia (HHT). Moreover a case was reported in 2012 showing an improvement of nosebleeds with the use of topical nasal timolol. The aim of the study is to evaluate timolol nasal spray efficacy in HHT. The main objective of this trial is to evaluate, 3 months after the end of the treatment, the efficacy on the duration of nosebleeds of a 4 weeks timolol intranasal treatment in HHT patients with nosebleeds (>20 min/month). Secondary objectives are to evaluate the tolerance, the efficacy at 6 months after the end of the treatment, and the efficacy on anemia and on clinical parameters (nosebleeds, quality of life and blood transfusions). This is a prospective double blind phase II study, randomized versus placebo using an allocation ratio of 1:1. A total of 58 patients will be included. The product (solution with timolol at 0.5% or placebo) is self-administered by the patient with a posology of one spray (50 µL) in each nostril twice a day for 28 consecutive days.

Nosebleeds that persist even after adequate traditional nasal packing may require aggressive treatment strategies to stop bleeding. Currently these strategies include a surgical approach to cut off blood supply to the vessel that is bleeding. FloSeal Hemostatic matrix is a gel like medical therapy that is inserted into the nose and is engineered to stop bleeding in severe cases, possibly avoiding the need for surgery. In this study the investigators will randomize patients to either receive FloSeal Hemostatix matrix or traditional nasal packing as a treatment for severe nosebleeds. The main outcome will be whether the investigators are able to stop bleeding with FloSeal or traditional packing alone and whether additional measures are necessary to stop the bleeding. The investigators will also perform a patient comfort survey and cost analysis. Even if FloSeal has equal effectiveness in treating nosebleeds as traditional packing, if it is much more comfortable for patients then it may be the favourable treatment.

The recognized manifestations of HHT are all due to abnormalities in vascular structure. Epistaxis due to telangiectases formation is spontaneous, very variable, recurrent in 90% of patients, and associated with severe anemia in 2-10%. They also significantly reduce quality of life. Improvement in epistaxis has been shown in HHT patients after a liver transplantation. It was hypothesized that the immunosuppressive treatment (FK506) used to prevent rejection may have an anti-angiogenic effect. The results of Albiñana et al suggest that the mechanism of action of FK506 involves a partial correction of endoglin and ALK1 haplosufficiency, genes responsible for 90% of HHT case. Tacrolimus ointment is available on the market for the treatment of eczema and can therefore readily be used as it is for nasal administration. Topical nasal administration of tacrolimus may be an easy local ENT treatment that is non-aggressive and results in little trauma for the patient in relation to other first line treatment possibilities. The main objective of this trial is to evaluate, at 6 weeks after the end of the treatment, the efficacy on the duration of nosebleeds, of 6 weeks tacrolimus nasal ointment application, in patients with HHT complicated by nosebleeds (30 min/6 weeks). Secondary objectives are to evaluate the tolerance throughout the study, the efficacy on anemia and on clinical parameters (nosebleeds, quality of life, epistaxis severity score questionnaire and blood transfusions) and the systemic absorption of nasal administration. This is a multicenter prospective and double blinded phase I/II trial. A total of 48 patients will be randomized versus placebo using an allocation ratio of 1:1. The ointment (Protopic® at 0.1% or placebo) will be self-administered by the patient with one administration in each nostril twice a day for 6 consecutive weeks.

The purpose of the NOSE Study is to carefully examine the efficacy and safety of 3 nasal sprays (bevacizumab, estriol, and tranexamic acid), compared to placebo, for the treatment of HHT related nosebleeds.

This is a research study to find out more about the use of Avastin (proper chemical name is bevacizumab) in the treatment of epistaxis (nose bleeding) in patients with Hereditary Hemorrhagic Telangiectasia (HHT).

Purpose: This study is a prospective clinical trial to investigate the efficacy of a chitosan-coated nasal packing (ChitoFlex® used in conjunction with the HemCon Nasal Plug) in the management of difficult spontaneous epistaxis and to evaluate its healing effect on nasal mucosa. The introduction of products that enhances hemostasis can have clinical advantages when associated with traditional nasal packing. These advantages include a better hemostatic control and the reduction of nasal packing duration. Furthermore, this study will help determine if there are any non-desirable effects that chitosan may have on the nasal cavity, such as the production of fibrosis and foreign body reaction.
