2019-10-29 14:36:34 | BioPortfolio

Summary

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.

Description

This study is a double-blinded, placebo-controlled, 8-week randomized clinical trial investigating the efficacy of timolol gel in the management of epistaxis in adults with HHT.

The Specific Aims are to determine in adults with HHT-associated epistaxis:

1. If topical timolol gel is more effective than placebo in reducing the frequency and severity of epistaxis.

2. If topical timolol gel is more effective than placebo in improving hemoglobin levels.

3. The frequency of adverse events, side effects, and safety profile of topical timolol gel delivered to the nasal mucosa.

Medical and Biotech [MESH] Definitions

An autosomal dominant vascular anomaly characterized by telangiectases of the skin and mucous membranes and by recurrent gastrointestinal bleeding. This disorder is caused by mutations of a gene (on chromosome 9q3) which encodes endoglin, a membrane glycoprotein that binds TRANSFORMING GROWTH FACTOR BETA.

A membrane glycoprotein and ANGIOGENESIS FACTOR that is expressed by cells of the VASCULAR ENDOTHELIUM; VASCULAR SMOOTH MUSCLE; and MONOCYTES. It functions as a co-receptor for TRANSFORMING GROWTH FACTOR BETA and modulates CELL ADHESION. Mutations in the endoglin gene are associated with cases of HEREDITARY HEMORRHAGIC TELANGIECTASIA.

A beta-adrenergic antagonist similar in action to PROPRANOLOL. The levo-isomer is the more active. Timolol has been proposed as an antihypertensive, antiarrhythmic, antiangina, and antiglaucoma agent. It is also used in the treatment of MIGRAINE DISORDERS and tremor.

A pharmaceutical preparation of brimonidine tartrate and timolol maleate. The combined ADRENERGIC ALPHA2 RECEPTOR AGONIST and ADRENERGIC BETA-ANTAGONIST activity of these drugs reduce INTRAOCULAR PRESSURE in GLAUCOMA patients.

A group of viral diseases of diverse etiology but having many similar clinical characteristics; increased capillary permeability, leukopenia, and thrombocytopenia are common to all. Hemorrhagic fevers are characterized by sudden onset, fever, headache, generalized myalgia, backache, conjunctivitis, and severe prostration, followed by various hemorrhagic symptoms. Hemorrhagic fever with kidney involvement is HEMORRHAGIC FEVER WITH RENAL SYNDROME.
