Definitions

  • the present invention is related generally to treatments for glaucoma and more specifically to agents which activate soluble guanylate cyclase (sGC) thereby lowering intraocular pressure such as that associated with glaucoma and ocular hypertension.
  • sGC soluble guanylate cyclase
  • the eye disease glaucoma is characterized by a permanent loss of visual function due to irreversible damage to the optic nerve.
  • the several morphologically or functionally distinct types of glaucoma are typically characterized by an undesirable elevation of intraocular pressure (IOP), which is considered to be causally related to the pathological course of the disease.
  • IOP intraocular pressure
  • Continuously elevated IOP has been associated with the progressive loss of retinal ganglion cells, optic nerve damage ultimately resulting in the loss of visual function.
  • ocular hypertension a condition in which IOP is elevated, can present without apparent loss of visual function.
  • patients with ocular hypertension are considered to be at a high risk for eventually developing the visual loss associated with glaucoma.
  • lowering IOP is the current treatment objective for the of glaucoma patients and for patients with ocular hypertension in order to decrease the potential for, or severity of, glaucomatous retinopathy.
  • many individuals do not respond well when treated with existing glaucoma therapies.
  • Glaucoma patients have relatively low IOP, yet present with glaucomatous visual field loss. These patients may benefit from agents that lower and control IOP, because glaucoma that is detected early and treated promptly may have reduced or delayed loss of visual function.
  • Conventional therapeutic agents that have proven to be effective for the reduction of IOP include both agents that decrease aqueous humor production and agents that increase the uveoscleral outflow. There are currently no approved agents that directly increase conventional outflow facility via trabecular meshwork and Schlemm's canal. Such agents are in general administered by one of two routes; topically by direct application to the eye, or orally.
  • Soluble guanylate cyclase is a receptor enzyme for the second messenger, nitric oxide (NO) in several cell types including muscle, epithelia, neuronal, and endothelial cells.
  • NO nitric oxide
  • functional sGC is a heterodimer composed of either an alpha 1 or alpha 2 subunit combined with the beta 1 subunit which has a heme prosthetic group.
  • NO binds to the prosthetic heme of sGC which activates the enzyme to catalyze the conversion of guanosine-5'-triphosphate (GTP) to cyclic guanosine monophosphate (cGMP).
  • GTP guanosine-5'-triphosphate
  • cGMP cyclic guanosine monophosphate
  • cGMP is a second messanger which in turn exerts its effects by activating cGMP dependent protein kinase (PKG) isoforms, phosphodiesterases, and cGMP gated ion channels.
  • PKG cGMP dependent protein kinase
  • sGC can thus modulate numerous pathways associated with diseases including hypertension (arterial and pulmonary), heart failure, atherosclerosis, erectile dysfunction, liver cirrhosis, and renal fibrosis.
  • oxidative stress can cause the oxidation of the heme group of sGC (from ferrous to ferric state) which is incapable of being activated by NO and can contribute to exacerbation of disease processes.
  • sGC oxidation and unresponsiveness to NO
  • endothelial dysfunction As a consequence of sGC oxidation and unresponsiveness to NO, endothelial dysfunction, atherosclerosis, hypertension, stable or unstable angina pectoris, thromboses, myocardial infarction, strokes or erectile dysfunction are worsened. Therefore, pharmacological stimulation or activation of sGC offers a possibility to normalize cGMP production and therefore makes possible the treatment and/or prevention of such disorders.
  • sGC stimulators are dependent on heme, but they are not active once sGC become oxidized.
  • sGC activators on the other hand can still activate the enzyme to generate cGMP even in the absence of nitric oxide (NO) synthesis, NO availability and oxidative stress induced heme iron oxidation of sGC in disease pathology.
  • NO nitric oxide
  • the present invention in part relates to methods of treating glaucoma in human patients or other mammals.
  • the present invention also relates to methods of lowering or controlling normal or elevated IOP in a human patient or other mammals.
  • the invention provides methods of treating and/or preventing glaucoma by administration of an sGC activator compound described infra.
  • Oxidative stress is thought to be an underlying factor that can adversely affect trabecular meshwork function, resulting from/in IOP elevation in POAG.
  • Reactive oxygen species ROS not only decrease the bioavailability of nitric oxide (NO) but also shift the sGC redox equilibrium to its oxidized form, which as mentioned before is unresponsive to NO.
  • Selective activation of the oxidized form of sGC should target only the diseased state of the target enzyme in the putative target tissue, trabecular
  • Certain embodiments of the present invention comprise compositions or methods which include or use compounds capable of activating sGC thereby modulating intraocular pressure in the eye.
  • sGC receptor activity By activating sGC receptor activity, subject compounds according to certain embodiments of the present invention are accordingly useful for lowering and/or controlling IOP associated with normal-tension glaucoma, ocular hypertension, and glaucoma, including primary open-angle glaucoma in humans and other warm-blooded animals.
  • the compounds may be formulated in pharmaceutical compositions suitable for topical delivery to the eye.

  • the present invention relates to a method of treating or preventing glaucoma or reducing intraocular pressure comprising administering to a subject in need thereof a sGC activator.
  • the invention has surprisingly shown, in a clinically relevant animal model, that administration of certain classese of sGC activators provides desirable sustained efficacy in reducing intraocular pressure (IOP) that is superior to reduction observed by administration of sGC stimulators.

  • sGC activators are useful in the treatment of glaucoma and ocular hypertension.
  • sGC activator is a compound capable of modulating sGC activity in pathologically changed heme-free sGC (i.e., following heme oxidation) to generate cGMP signaling which would otherwise be unresponsive to nitric oxide.
  • sGC stimulators refers to compounds that are capable of synergizing with nitric oxide and can directly stimulate cGMP production so long as the heme domain is present in the enzyme.

Description

sGC ACTIVATORS FOR THE TREATMENT OF GLAUCOMA
FIELD OF THE INVENTION
The present invention is related generally to treatments for glaucoma and more specifically to agents which activate soluble guanylate cyclase (sGC) thereby lowering intraocular pressure such as that associated with glaucoma and ocular hypertension.
BACKGROUND OF THE INVENTION
The eye disease glaucoma is characterized by a permanent loss of visual function due to irreversible damage to the optic nerve. The several morphologically or functionally distinct types of glaucoma are typically characterized by an undesirable elevation of intraocular pressure (IOP), which is considered to be causally related to the pathological course of the disease. Continuously elevated IOP has been associated with the progressive loss of retinal ganglion cells, optic nerve damage ultimately resulting in the loss of visual function. In some cases, ocular hypertension, a condition in which IOP is elevated, can present without apparent loss of visual function. However, patients with ocular hypertension are considered to be at a high risk for eventually developing the visual loss associated with glaucoma. Therefore, lowering IOP is the current treatment objective for the of glaucoma patients and for patients with ocular hypertension in order to decrease the potential for, or severity of, glaucomatous retinopathy. Unfortunately, many individuals do not respond well when treated with existing glaucoma therapies.
Patients known as normotensive or low-tension glaucoma patients have relatively low IOP, yet present with glaucomatous visual field loss. These patients may benefit from agents that lower and control IOP, because glaucoma that is detected early and treated promptly may have reduced or delayed loss of visual function. Conventional therapeutic agents that have proven to be effective for the reduction of IOP include both agents that decrease aqueous humor production and agents that increase the uveoscleral outflow. There are currently no approved agents that directly increase conventional outflow facility via trabecular meshwork and Schlemm's canal. Such agents are in general administered by one of two routes; topically by direct application to the eye, or orally.
However, many of these agents have associated side effects which may render them undesirable as ocular therapeutic agents.
Soluble guanylate cyclase (sGC) is a receptor enzyme for the second messenger, nitric oxide (NO) in several cell types including muscle, epithelia, neuronal, and endothelial cells. In humans, functional sGC is a heterodimer composed of either an alpha 1 or alpha 2 subunit combined with the beta 1 subunit which has a heme prosthetic group. Under physiological conditions, NO binds to the prosthetic heme of sGC which activates the enzyme to catalyze the conversion of guanosine-5'-triphosphate (GTP) to cyclic guanosine monophosphate (cGMP). cGMP is a second messanger which in turn exerts its effects by activating cGMP dependent protein kinase (PKG) isoforms, phosphodiesterases, and cGMP gated ion channels. In doing so, sGC can thus modulate numerous pathways associated with diseases including hypertension (arterial and pulmonary), heart failure, atherosclerosis, erectile dysfunction, liver cirrhosis, and renal fibrosis. Under aforementioned pathologic conditions prolonged oxidative stress can cause the oxidation of the heme group of sGC (from ferrous to ferric state) which is incapable of being activated by NO and can contribute to exacerbation of disease processes. As a consequence of sGC oxidation and unresponsiveness to NO, endothelial dysfunction, atherosclerosis, hypertension, stable or unstable angina pectoris, thromboses, myocardial infarction, strokes or erectile dysfunction are worsened. Therefore, pharmacological stimulation or activation of sGC offers a possibility to normalize cGMP production and therefore makes possible the treatment and/or prevention of such disorders.
To this effort, there are two classes of compounds have been identified, including NO- independent/reduced heme-dependent sGC stimulators and NO-independent/heme-independent sGC activators. sGC stimulators are dependent on heme, but they are not active once sGC become oxidized. sGC activators on the other hand can still activate the enzyme to generate cGMP even in the absence of nitric oxide (NO) synthesis, NO availability and oxidative stress induced heme iron oxidation of sGC in disease pathology. Thus the activity of sGC in these situations will be corrected by sGC activators, but not by sGC stimulators, and will have the potential to provide benefit in many diseases caused by defective signaling in the NO pathway especially following oxidative stress.
SUMMARY OF THE INVENTION
The present invention in part relates to methods of treating glaucoma in human patients or other mammals. The present invention also relates to methods of lowering or controlling normal or elevated IOP in a human patient or other mammals. In particular, the invention provides methods of treating and/or preventing glaucoma by administration of an sGC activator compound described infra.
In the eye, the trabecular outflow pathway by which 70-80% of aqueous humor would normally leave the anterior chamber of the eye and lower intraocular pressure (IOP), is
pathologically compromised in primary open angle glaucoma (POAG). Oxidative stress is thought to be an underlying factor that can adversely affect trabecular meshwork function, resulting from/in IOP elevation in POAG. Reactive oxygen species (ROS) not only decrease the bioavailability of nitric oxide (NO) but also shift the sGC redox equilibrium to its oxidized form, which as mentioned before is unresponsive to NO. Selective activation of the oxidized form of sGC should target only the diseased state of the target enzyme in the putative target tissue, trabecular
meshwork/Schlemm's canal tissue, thus offering a highly innovative therapy for glaucoma that should work adjunctively with current therapies. Certain embodiments of the present invention comprise compositions or methods which include or use compounds capable of activating sGC thereby modulating intraocular pressure in the eye. By activating sGC receptor activity, subject compounds according to certain embodiments of the present invention are accordingly useful for lowering and/or controlling IOP associated with normal-tension glaucoma, ocular hypertension, and glaucoma, including primary open-angle glaucoma in humans and other warm-blooded animals. When used in such applications, the compounds may be formulated in pharmaceutical compositions suitable for topical delivery to the eye.
Certain sGC activators which are contemplated for use in the methods of the instant invention include those compounds prepared and disclosed by WO2009/032249, WO2012/058132, WO2010/099054, WO2009/071504, WO2012/122340, WO2013/025425 and WO2009/068652, each of which is incorporated by reference.
The foregoing brief summary broadly describes the features and technical advantages of certain embodiments of the present invention. Additional features and technical advantages will be described in the detailed description of the invention that follows. Novel features which are believed to be characteristic of the invention will be better understood from the detailed description of the invention when considered in connection with any accompanying figures. However, figures provided herein are intended to help illustrate the invention or assist with developing an understanding of the invention, and are not intended to be definitions of the invention's scope
DESCRIPTION OF THE INVENTION
In a first embodiment, the present invention relates to a method of treating or preventing glaucoma or reducing intraocular pressure comprising administering to a subject in need thereof a sGC activator. The invention has surprisingly shown, in a clinically relevant animal model, that administration of certain classese of sGC activators provides desirable sustained efficacy in reducing intraocular pressure (IOP) that is superior to reduction observed by administration of sGC stimulators. Thus, sGC activators are useful in the treatment of glaucoma and ocular hypertension.
As the term are used herein, a "sGC activator" is a compound capable of modulating sGC activity in pathologically changed heme-free sGC (i.e., following heme oxidation) to generate cGMP signaling which would otherwise be unresponsive to nitric oxide. In contrast, "sGC stimulators" refers to compounds that are capable of synergizing with nitric oxide and can directly stimulate cGMP production so long as the heme domain is present in the enzyme.
In a second embodiment, the invention provides methods of treating or preventing glaucoma or reducing intraocular pressure according to the first embodiment in which the method comprises administering to a subject in need of such therapy a sGC activator selected from compounds specifically or generically disclosed in international patent application WO 2009/032249 which is incorporated by reference for the compounds disclosed therein. In particular, the second embodiment provides for the administration of a sGC activator of formula (I):

CHO cell-based assay
Chinese hamster ovary (CHO) cells overexpressing soluble guanylate cyclase were generated to test the effect of sGC activators in a cellular context. Human cDNAs for GUCYA3 (RefSeq: NM_000856.3) and GUCYB3 (RefSeq: NM_000857.1 ) were amplified by PCR from a HUVEC (Human Umbilical Vein Endothelial Cells) cDNA library and cloned into mammalian expression vectors. CHO K1 cells (ATCC CCL-61 ) were transfected using Lipofectamine 2000 following manufacturer's instructions and stably expressing clones were identified by antibiotic selection. CHO GUCY clone 8E10 was used for subsequent experiments.
Cells were seeded at a density of 3000 cells/well in white 384-well proxyplates (Perkin Elmer) and incubated overnight, then the medium was removed and cells were washed with assay buffer (HBSS, 0.1 % BSA, 1 mM IBMX, 20uM ODQ). sGC activators were serially diluted in DMSO, then diluted in assay buffer prior to adding to cells (10ul/well, final DMSO concentration 0.5%). Cells were incubated with compounds for 1 h room temperature, then assayed for cGMP production using Cisbio cGMP HTRF kit (62GM2PEC) according to manufacturer's instructions. The EC50s are calculated based on the amount of cGMP interpolated from the standard curve, using a 4-parameter sigmoidal dose-response.

Determination of Intraocular Pressure (lOP) in Lasered (Hypertensive) Eyes of Cynomolgus Monkeys
Conscious intraocular pressure (lOP) was determined with an Alcon Pneumatonometer (Alcon Laboratories, Inc., Fort Worth, TX.) after light corneal anesthesia with 0.25% proparacaine. Right eyes were hypertensive as a result of laser trabeculoplasty. Left eyes were intact and with normal lOP. After a baseline lOP measurement, the animals were randomly divided into two groups with similar group mean of lOP. Compounds in Formula 1 vehicle were administered topical ocular of both eyes in 8-9 conscious ocular hypertensive Cynomolgus monkeys. The Formula 1 vehicle used in the current studies include hydroxypropyl methylcellulose (0.5%), anhydrous dibasic sodium phosphate (0.2-0.5%), sodium chloride (0.5-0.75%), disodium EDTA (Edetate disodium) (0.01 %), polysorbate 80, (0.05%), benzalkonium chloride (0.01 %), sodium hydroxide/hydrochloric acid (for adjusting pH to 7.3-7.4), and purified water (q.s. to 100%), Vehicle was instilled in both eyes of 8-9 additional animals as control. Subsequent lOP measurements were typically taken at 1 , 3, 6, and 24 hours post-dose. The percent change in lOP from baseline was determined for each animal for every IOP measurement. Group mean and standard error of the mean (SEM) were calculated. Statistical significance of IOP change from baseline and also versus treatment groups were determined by repeated measures ANOVA and Bonferroni t-test at p<0.05.
The compounds listed below were formulated and dosed either as a once-daily (QD) topical ocular administration or twice daily administration (BID) in laser-induced ocular hypertensive cynomolgus monkeys along with a separate group of monkeys treated with vehicle formulation (n = 8-9 monkeys per group). * Denotes statistical significance of average percent IOP reduction from baseline (pre-dose) IOP and versus vehicle dosed group.
