Anti-S1P antibody treatment of patients with ocular disease
View Patent ↗The present invention relates to methods that involve administration of an anti-S1 P antibody or antibody fragment or derivative to a subject having or suspected of having an ocular disease or condition, including one involving choroidal neovascularization, in order to achieve a desired effect. Such effects include reducing the size of a choroidal neovascularization lesion in the eye, decreasing or resolving retinal pigment epithelial detachment, decreasing central retinal lesion thickness, and preserving or improving visual acuity. Pharmaceutical compositions comprising an anti-S1 P antibody for ocular administration are also provided. The compositions and methods are particularly useful for treating subjects having age-related macular degeneration, particularly exudative or wet age-related macular degeneration.
1. A method selected from the group consisting of:
(a) a method of treating a subject having an occult or minimally classic choroidal neovascularization lesion, comprising administering an anti-sphingosine-1-phosphate (S1P) antibody or S1P-binding antibody fragment in an amount sufficient to reduce the size of the choroidal neovascularization lesion;
(b) a method of treating retinal pigment epithelial detachment, comprising administering to an affected eye of a subject having or suspected of having retinal pigment epithelial detachment, an anti-S1P antibody or S1P-binding antibody fragment in an amount sufficient to stabilize or decrease the retinal pigment epithelial detachment;
(c) a method of reducing central retinal thickness in an eye of a subject having an occult or minimally classic choroidal neovascularization lesion, comprising administering an anti-S1P antibody or S1P-binding antibody fragment in an amount sufficient to cause a reduction in central retinal thickness of the eye; and
(d) a method for preserving or improving visual acuity in a patient having or suspected of having an occult or minimally classic choroidal neovascularization lesion, comprising administering an anti-S1P antibody or S1P-binding antibody fragment in an amount sufficient to preserve or improve visual acuity.
2. A method according to claim 1 wherein the anti-S1P antibody or S1P-binding antibody fragment is administered via ocular administration, optionally via intravitreal injection.
3. A method according to claim 1 wherein the subject has or is suspected of having age-related macular degeneration.
4. A method according to claim 3 wherein the age-related macular degeneration is exudative age-related macular degeneration.
5. A method according to claim 1 (b) wherein said treating results in a resolution of pigment epithelial detachment.
6. A method according to claim 1 (b) wherein the retinal pigment epithelial detachment stems from age-related macular degeneration.
7. A method according to claim 6 wherein the age-related macular degeneration is exudative age-related macular degeneration.
8. A method according to claim 1 (c) wherein the choroidal neovascularization is occult and/or minimally classic choroidal neovascularization.
9. A method of treating an ocular disease or condition, comprising administering an effective amount of an ocular pharmaceutical formulation comprising an anti-sphingosine-1-phosphate (S1P) antibody or S1P-binding antibody fragment, a buffer, sodium chloride, and an ionic surfactant, wherein the ocular pharmaceutical formulation has a pH within the range of about pH 6 to about pH 7, to an eye of a subject known to have or suspected of having an ocular disease or condition correlated with S1P, wherein the ocular disease or condition is occult or minimally classic CNV, retinal pigment epithelial detachment, or thickening of the retina or loss of visual acuity associated with occult or minimally classic CNV.
10. A method according to claim 9 , wherein the formulation is administered via ocular administration, optionally via intravitreal injection.
11. A method according to claim 10 wherein the age-related macular degeneration is exudative age-related macular degeneration.
