This invention is directe to the use of non-steroidal glucocorticoid antagonists for treating glaucoma or ocular hypertension resulting from altered expression of the GLU 1 A gene (hereinafter GLC1A or 1 q glaucoma) in an individual.

BACKGROUND OF ThlE INVENTION The glaucomas are a heterogeneous group of optic neuropathies characterized by cupping of the optic nerve head, thinning of the retinal nerve fiber layer due to loss of retinal ganglion cells, and specific pathognomonic changes in visual fields.

Elevated intraocular pressure (IOP) is a very important risk factor for the development of most common forms of glaucoma (Sommer A, et al. Relationship between intraocular pressure and primary open angle glaucoma among white and black Americans. Arch. Ophthalmol. 109: 1090-1095,1991).

A family history of glaucoma also is an important risk factor for the development of glaucoma. It appears that a significant portion of glaucoma is inherited (or at least the risk for developing glaucoma is inherited) although it is often difficult to establish clear inheritance patterns for most of the glaucomas because of the disease onset late in life and the slowly progressive clinical manifestations of the disease. Despite these problems, a number of families with heritable forms of glaucoma have been identifie and these families have been used to map a variety of

glaucoma genes (Sheffield, et al., "Genetic Linkage of Familial Open Angle Glaucoma to Chromosome 1q21-q31,"Nature Genetics, 4: 47-50 (1993); Sarfarazi, et al.,"Assignment"Assignment of a Locus (GLC3A) for Primary Congenital Glaucoma (Buphthalmos) to 2p21 and Evidence for Genetic Heterogeneity,"Genomics, 30: 171- 177 (1995); Akarsu, et al., "A Second Locus (GLC3B) for Primary Congenital Glaucoma (Buphthalmos) Maps to the lp36 Region,"Human Molecular Genetics, 5 (8): 1199-1203 (1996); Stoilova, et al., "Localization of a Locus (GLC 1 B) for Adult- Onset Primary Open Angle Glaucoma to the 2cen-ql3 Region,"Genomics, 36: 142- 150 (1996); Wirtz, et al., "Mapping a Gene for Adult-Onset Primary Open-Angle Glaucoma to Chromosome 3q,"Am. J. Hum. Genet., 60: 296-304 (1997); Andersen, et al., "A Gene Responsible for the Pigment Dispersion Syndrome Maps to Chromosome 7q35-q36,"Arch. Ophthalmol., 115: 384-388 (1997)). The first glaucoma gene mapped (GLC 1 A) was in a large family with autosomal dominant inherited juvenile glaucoma (JG). This disease is characterized by an early disease onset (late teens to early 20s), relatively high IOPs, and general resistance to conventional pharmacological IOP lowering therapy. The GLC1A gene was mapped by positional cloning and linkage analysis to chromosome lq22-q25 (Sheffield et al, Id.) and a number of other groups have confirme the lq location of this juvenile glaucoma gene (Richards, et al., "Mapping of a Gene for Autosomal Dominant Juvenile-Onset Open-Angle Glaucoma to Chromosome lq,"Am. J. Hum. Genet., 54: 62-70 (1994); Morissette, et al., "A Common Gene for Juvenile and Adult-Onset Primary Open-Angle Glaucomas Confine on Chromosome 1 q,"Am. J. Hum. Genet., 56: 1431-1442 (1995); Wiggs, et al., "Genetic Linkage of Autosomal Dominant Juvenile Glaucoma to lq21-q31 in Three Affecte Pedigrees,"Genomics, 21: 299-303 (1994); Meyer, et al., "Age-Dependent Penetrance and Mapping of the Locus for Juvenile and Early-Onset Open-Angle Glaucoma on Chromosome lq (GLC1A) in a French Family,"Hum. Genet., 98: 567-571 (1996); Graff, et al., "Confirmation of Linkage to 1 q21-31 in a Danish Autosomal Dominant Juvenile-Onset Glaucoma

Family and Evidence of Genetic Heterogeneity,"Hum. Genet., 96: 285-289 (1995)).

Glaucoma due to the GLU 1 A gene is often referred to as lq glaucoma.

The GLC1A gene was identifie as encoding a 57 kD protein expressed in the trabecular meshwork (TM) (Stone, et al., "Identification of a Gene That Causes Primary Open Angle Glaucoma,"Science, 275: 668-670 (1997)). The expression of the GLC1A gene, and the encoded TM protein, is up-regulated by glucocorticoids (Polansky, et al., "Eicosanoid Production and Glucocorticoid Regulatory Mechanisms in Cultured Human Trabecular Meshwork Cells,"The Ocular Effects of Prostaglandins and Other Eicosanoids, pp. 113-138 (1989); Polansky, et al.,"In Vitro Correlates of Glucocorticoid Effects on Intraocular Pressure,"Glaucoma Update IV (1991); and Polansky, et al., "Cellular Pharmacology and Molecular Biology of the Trabecular Meshwork Inducible Glucocorticoid Response Gene Product,"Ophthalmologica, 211: 126-139 (1997)). This TM protein is also known as TIGR (trabecular meshwork inducible glucocorticoid response) (Polansky, Id.). The glucocorticoid-induction of this TM protein has been suggested to be involved in the generation of glucocorticoid-induced ocular hypertension and glaucoma (Polansky, Id.).

The GLC1A gene is expressed in other ocular tissues such as the ciliary epithelium (Ortego, et al., "Cloning and Characterization of Subtracted cDNAs from a Human Ciliary Body Library Encoding TIGR, a Protein Involved in Juvenile Open Angle Glaucoma with Homology to Myosin and Olfactomedin,"FEBS Letters, 413: 349-353 (1997)) and the retina (Kubota, et al., "A Novel Myosin-like Protein (Myocilin) Expressed in the Connecting Cilium of the Photoreceptor: Molecular Cloning, Tissue Expression, and Chromosomal Mapping,"Genomics, 41: 360-369 (1997)). The gene is referred to by several names including GLC1A (Sheffield, supra; Sunden, et al., "Fine Mapping of the Autosomal Dominant Juvenile Open

Angle Glaucoma (GLC 1 A) Region and Evaluation of Candidate Genes,"Genome Research, 6: 862-869 (1996); Stone, et al., supra), TIGR (Polansky supra; Ortego, supra), and myocilin (Kubota, supra). Mutations GLClA are not only responsible for juvenile glaucoma, but also a significant subset of adult onset primary open angle glaucoma (Stone, et al., supra; Adam, et al., "Recurrent Mutations in a Single Exon Encoding the Evolutionarily Conserve Olfactomedin-Homology Domain of TIGR in Familial Open-Angle Glaucoma,"Human Molecular Genetics, 6 (12): 2091-2097 (1997)). The lq glaucoma gene (GLC1A, TIGR) is the subject of Nguyen, et al., U. S. Patent No. 5,606,043, issued February 25,1997.

Glucocorticoids have been associated with the development of ocular hypertension and primary open angle glaucoma (Kass, et al.,"Corticosteroid-Induced Glaucoma, In Ritch, R., Shields, M. B., Krupin, T. (eds.), "The Glaucomas, The C. V.

Eye Res., 27: 567-575 (1978); Francois, et al.,"Ultrastructural and Morphometric Study of Corticosteroid Glaucoma in Rabbits, Ophthalmic Res., 16: 168-178 (1984); Lorenzetti, O. J., "Effects of Corticosteroids on Ocular Dynamics in Rabbits,"J Phannacol. Exp. Therap., 175: 763-772 (1970); and Zhan, et al., "Steroid Glaucoma: Corticosteroid-Induced Ocular Hypertension in Cats,"Exp. Eye Res., 54: 211-218 (1992)). Glaucoma patients have also been reporte to have higher levels of the endogenous glucocorticoid, cortisol (Rozsival, et al., "Aqueous Humour and Plasma Cortisol Levels in Glaucoma and Cataract Patients,"Current Eye Research, 1: 391-396 (1981); Ray, et al., "Plasma Cortisol in Glaucoma,"Ann. Ophthalmol., 9: 1151-1154 (1977); and Schwartz, et al., "Increased Plasma Free Cortisol in Ocular Hypertension and Open Angle Glaucoma,"Arch. OpAthalmol., 105: 1060-1065

(1987)).

It is known that trabecular meshwork cells have glucocorticoid receptors and that glucocorticoid binding with these receptors causes a change in trabecular meshwork cell gene expression. Known manifestations of this change include a reorganization of the cytoskeleton (Wilson, et al., "Dexamethasone Induced Ultrastructural Changes in Cultured Human Trabecular Meshwork Cells, Cur. Eye Res., 12: 783-793 (1993), and Clark, et al., "Glucocorticoid-Induced Formation of Cross- Linked Actin Networks in Cultured Human Trabecular Meshwork Cells,"Invest.

Ophthalmol. Vis. Sci., 35: 281-294 (1994)) and increased deposition of the extracellular matrix material in trabecular meshwork cells. As a result, the trabecular meshwork becomes"clogged"and unable to perform one of its most critical functions, that is, serving as a gateway for aqueous humor flow from the anterior chamber of the eye.

When the aqueous humor flow out of the eye via the trabecular meshwork is diminished, the intraocular pressure of the eye rises. If this state of elevated intraocular pressure is maintained or frequently occurs, the optic nerve head can be damaged resulting in the loss of visual field. Loss of visual field is the hallmark symptom associated with glaucoma.

Endogenous glucocorticoids may be responsible for producing the changes in the trabecular meshwork that lead to ocular hypertension and glaucoma. In the present case, it is believed that non-steroidal glucocorticoid antagonists bind to the glucocorticoid receptor in trabecular meshwork cells, and thereby prevent binding of endogenous glucocorticoids to the glucocorticoid receptor. They may also displace endogenous glucocorticoids which are bound to glucocorticoid receptors.

In summary, the GLC1A gene product can lead to the development of ocular hypertension and glaucoma in one of two ways: (1) mutations in GLC1A are

responsible for most forms of juvenile glaucoma and a subset of adult onset POAG or (2) exposure of some individuals to glucocorticoids leads to increased GLClA expression in the TM which causes increased aqueous humor outflow resistance and the development of ocular hypertension. The precise mechanism (s) responsible for GLC 1 A effects on IOP are currently unknown.

SUMMARY OF THE INVENTION Non-steroidal glucocorticoid antagonists (NSGAs) and their pharmaceutical formulations are useful for treating GLU 1 A glaucoma. The invention is also directe to methods for controlling GLC 1 A glaucoma using NSGAs, some of which are novel.

DESCRIPTION OF THE PREFERRED EMBODIMEENTS Agents which alter the expression of GLC1A in the glaucomatous eye are expected to lower IOP and thereby prevent or inhibit the glaucomatous optic neuropathy which is being driven by elevated IOP. Glucocorticoids upregulte GLC1A expression in the TM of certain individuals. There have been several reports of elevated levels of the natural glucocorticid cortisol in the aqueous humor and plasma of glaucoma patients (Schwartz, et al. , ;supra Rozsival, et al. , supra). In addition, certain mutations in GLC 1 A may alter the expression of GLC1A in the TM tissue of 1q glaucoma patients. Unexpectedly, it has been discovered that certain non-steroidal glucocorticoid antagonists (NSGA) inhibit the expression of GLC1A in cultured human TM cells and lower elevated IOP in certain animal models of ocular hypertension. The NSGAs appear to work by inhibiting glucocorticoids from binding to the glucocorticoid receptor or displacing prebound steroids from the glucocorticoid receptor in the trabecular meshwork. The NSGAs thereby prevent the expression of GLC1A and the subsequent development of ocular hypertension.

Ketoconazole and clotrimazole are known glucocorticoid antagonists. (Loose, et al., "Ketoconazole Binds to Glucocorticoid Receptors and Exhibits Glucocorticoid Antagonist Activity in Cultured Cells,"J Clin. Invest. , :72 404-408 (1983)). They are not known to be useful in treating or controlling glaucoma.
