Definitions
- the present invention relates to bromocriptine for use in treating eye diseases associated with elevated level of vascular endothelial growth factor (VEGF) and a pharmaceutical composition for use in treating eye diseases associated with elevated level of VEGF comprising bromocriptine and a pharmaceutically acceptable carrier.
- VEGF vascular endothelial growth factor
- Angiogenesis means formation of new blood vessels.
- Angiogenesis is associated with many physiological and pathological processes, e.g., formation of collateral circulation in the myocardium or formation of solid tumor vascularization.
- the angiogenesis process is mediated by VEGF.
- VEGF is released by many cells and tissues, including endothelial cells of blood vessels, which is mediated by various factors, e.g., an inflammatory factor, and in response to hypoxia.
- the released VEGF acting through the receptors, causes loosening of junctions between vascular endothelial cells and migration of the endothelial cells through the vascular wall.
- Migrating vascular endothelial cells arrange themselves into tubular structures, which form primordia of the new blood vessels.
- VEGF-mediated loosening of junctions between endothelial cells forming a natural barrier in blood vessels is associated with the penetration of fluid into the extravascular space, which leads to swelling of the surrounding tissues.
- pathological angiogenesis plays an important role in diseases such as AMD (age- related macular degeneration), including, in particular, exudative AMD, retinal artery embolism, retinal vein occlusion, diabetic macular edema, or diabetic retinopathy.
- AMD age-related macular degeneration
- retinal artery embolism CAD
- retinal vein occlusion CAD
- diabetic macular edema CAD
- diabetic retinopathy diabetic macular edema
- Diabetic macular edema develops in patients with long-standing diabetes and more advanced form of diabetic retinopathy. It occurs in approximately 14% of diabetics. The incidence of DME depends on severity of retinopathy and the duration and type of diabetes. Approximately 30% of patients with type 1 and type 2 diabetes treated with insulin and approximately 15% of patients with type 2 diabetes treated with oral antidiabetic drugs, after 25 years of having diabetes, develop DME. Diabetic macular edema is defined as the presence of fluid or hard exudates within 1 dd (disc diameter) from the macular center.
- Diabetic retinopathy is currently the most common cause of blindness in developed countries. The reason for that is the increased incidence of diabetes in these countries. According to WHO, in 2002, diabetic retinopathy caused blindness in 1.8 million people (4.8%) worldwide. In the USA, it causes blindness in 12-24 thousand diabetics every year. Clinically, DR takes several forms such as non-proliferative retinopathy, pre-proliferative retinopathy, diabetic maculopathy, proliferative retinopathy, and advanced diabetic retinopathy. In most of these forms, it comes to retinal edema and in case of proliferative forms, to abnormal blood vessel overgrowth as well.
- Embolism of the central retinal artery or its branch is relatively rare. It is characterized by a sudden, painless vision loss. With prompt treatment, vision is fully or partially restored.
- One of the complications of central retinal artery embolism is the formation of pathological blood vessels within the eye tissue.
- Retinal vein occlusion means blockade of the main retinal vein (central retinal vein occlusion, CRVO) or a branch thereof (branch retinal vein occlusion, BRVO). It leads to various degrees of visual impairment. CRVO and BRVO are the second most common retinal vascular condition. The ischemic form is less common than the non-ischemic form. Retinal vein occlusions occur with a frequency of about 2 per 1000 in people over the age of 40, and more than 5 per 1000 in people over 64 years of age. As in case of central retinal artery embolism, in case of retinal vein occlusion, there may be late complications involving formation of new pathological blood vessels within retina and other eye tissues, e.g., in the filtration angle or in the iris.
- AMD is the leading cause of vision loss in people over the age of 50. It occurs in 8.8% of the population, more often in women, its frequency increases with age and it affects almost 28% of people over the age of 75. Worldwide, the number of patients reaches 50 million. Due to population aging, the problem of AMD is increasing, and about 10% of people over 45 are at risk of suffering from this condition. 90% of AMD cases consist of the dry form of AMD, with atrophic lesions within macula and gradual vision loss. 10% of patients with AMD have wet (exudative) AMD, where new blood vessels are formed in the retina and choroid (choroidal neovascularization, CNV), which rapidly leads to severe visual impairment or vision loss.
- CNV choroidal neovascularization
- Exudative AMD is responsible for most cases of vision loss. It is related to the retinal edema that occurs as a result of the disruption of the blood-retina barrier and growth of new pathological blood vessels. Newly formed vessels are brittle and leaky, which aggravates the pathological retinal edema and can lead to retinal detachment. In case of such changes which occur within central area of the retina, called the macula, a central scotoma appears in the patient’s field of view, which prevents functioning in everyday life. Also in the course of diabetes there is an increased release of VEGF due to increased blood sugar level (hyperglycemia) and the action of the so-called advanced (protein) glycation end products (AGEs).
- VEGF blood sugar level
- AGEs advanced (protein) glycation end products
- VEGF inhibitors or VEGF receptors inhibitors such as ranibizumab (fragment of recombinant humanized anti-VEGF-A monoclonal antibody), bevacizumab (recombinant humanized anti-VEGF-A monoclonal antibody) and aflibercept (VEGF receptor Fc fragment) are used to reduce swelling of the eye tissues and to inhibit angiogenesis. They are given as repeated intravitreal injections, usually at intervals of one or two months. The injectable form of VEGF inhibitor administration requires sterile administration conditions, limits the number of potential patients and is associated with the complication risk.
- bromocriptine has an inhibitory effect on VEGF release and action, and VEGF-A and VEGF-A receptor (VEGF-R2) gene expression in an angiogenesis model, which is significantly more potent than inhibitory effect of the known agents, including other type 2 dopaminergic receptor agonists such as cabergoline and pergolide.
- Bromocriptine (Formula 1) is a semisynthetic derivative of the ergot alkaloid ergocriptine. It is used in the prevention or inhibition of postpartum lactation for medical reasons, in hyperprolactinemia, amenorrhea, galactorrhea or menstrual cycle disorders, galactorrhea with normoprolactinemia, pituitary adenomas such as prolactinoma, acromegaly, and Parkinson's disease. Bromocriptine stimulates D2 type dopaminergic receptors.
- the present invention therefore provides bromocriptine for use in treating eye diseases associated with elevated level of vascular endothelial growth factor (VEGF), increased vascular permeability and abnormal angiogenesis processes.
