Ophthalmic composition for treatment of dry eye disease
The invention provides ophthalmic compositions comprising about 0.1% (w/v) cyclosporine dissolved in 1-(perfluorobutyl)pentane for use in the topical treatment of dry eye disease and provides for treatment methods thereof. The invention further provides kits comprising such compositions.
1. A method for increasing tear production volume in a patient in need thereof, wherein the patient suffers from keratoconjunctivitis sicca, comprising topically administering to the eye of the patient a daily dosage of 20 μg of cyclosporine, wherein the cyclosporine is administered as an ophthalmic composition comprising 0.1% (w/v) cyclosporine dissolved in 1-(perfluorobutyl)pentane, and optionally up to 1.0% (w/w) ethanol, wherein the composition is topically administered twice per day as a single drop per dose per eye, wherein the drop has a volume of about 8 to 10 μl; and
wherein the patient in at least one eye, or alternatively both eyes, is characterized by a Schirmer's Test 1 score of between 3 mm and 7 mm.
2. The method according to claim 1 , wherein the composition consists of 0.1% (w/v) cyclosporine dissolved in 1-(perfluorobutyl)pentane and 1.0% (w/w) ethanol.
3. The method according to claim 1 , wherein the composition consists of 0.1% (w/v) cyclosporine dissolved in 1-(perfluorobutyl)pentane.
4. The method according to claim 1 , wherein the patient's tear production is suppressed or is presumed to be suppressed because of ocular inflammation associated with keratoconjunctivitis sicca.
5. The method according to claim 4 , wherein the patient having keratoconjunctivitis sicca experiences any one of, or a combination of tear hyperosmolarity, tear film instability or abnormalities in the lipid layer composition of the tear film.
6. The method according to claim 4 , wherein the keratoconjunctivitis sicca is caused by ocular surgical intervention.
7. The method according to claim 4 , wherein the patient is unresponsive to prior treatment of keratoconjunctivitis sicca.
8. The method according to claim 4 , wherein the composition is effective in reducing one or more signs and/or symptoms of keratoconjunctivitis sicca.
9. The method according to claim 1 , wherein the patient has a total ocular surface disease index (OSDI) score of equal or greater than 45.
10. The method according to claim 1 , wherein the patient in at least one eye, or alternatively both eyes, is further characterized by:
(a) a total corneal fluorescein staining score of ≥10 according to NEI grading; and/or
(b) a total lissamine green conjunctival score (sum of temporal and nasal regions) of ≥2 according to the Oxford scale.
11. The method according to claim 1 , wherein the Schirmer's test is performed without anesthesia.
12. The method according to claim 1 , wherein the composition is substantially free of a preservative.
13. The method according to claim 12 , wherein the composition is effective in inhibiting microbial growth.
14. The method according to claim 13 , wherein the composition is provided in a container for holding multiple (a plurality) of doses of the composition.
15. The method according to claim 1 , wherein the composition is in the form of a clear solution.
16. The method according to claim 1 , wherein the patient has a total ocular surface disease index (OSDI) score of equal or greater than 55.
17. The method according to claim 1 , wherein the onset of effect is within 2 weeks.
