Ocular inserts comprising a covalently linked steroid dimer
The disclosure relates to compounds and compositions for sustained release of ocular therapeutics.
1. A method of treating a posterior ocular disorder or condition of an eye of a subject in need thereof, the method comprising intravitreally administering to the eye of the subject in need thereof an intravitreal implant comprising a steroidal compound represented by the structure:
the implant comprising the steroidal compound in an amount of at least 95% (w/w), thereby treating the posterior ocular disorder or condition of the eye of the subject in need thereof, the posterior ocular disorder or condition of the eye being macular edema or uveitis.
2. The method of claim 1 , wherein the implant comprises the steroidal compound in an amount of at least 98% (w/w).
3. The method of claim 1 , wherein the implant is a fiber, fiber mesh, woven fabric, non-woven fabric, pellet, cylinder, hollow tube, microparticle, nanoparticle, or shaped article.
4. The method of claim 3 , wherein the implant is a cylinder.
5. The method of claim 1 , wherein the implant releases the steroidal compound or dexamethasone in its free form in an amount sufficient to treat the posterior ocular disorder or condition of the eye of the subject in need thereof.
6. The method of claim 1 , wherein the implant releases the steroidal compound or dexamethasone in its free form over a period of at least a day.
7. The method of claim 6 , wherein the implant releases the steroidal compound or dexamethasone in its free form over a period of a least a month.
8. The method of claim 7 , wherein the implant releases the steroidal compound or dexamethasone in its free form over a period of at least a year.
9. The method of claim 1 , wherein the posterior ocular disorder or condition is macular edema.
10. The method of claim 9 , wherein the macular edema is diabetic macular edema (DME).
11. The method of claim 9 , wherein the macular edema is macular edema from a retinal disorder.
12. The method of claim 11 , wherein the retinal disorder is a retinal vein occlusion (RVO).
13. The method of claim 12 , wherein the retinal vein occlusion is a central RVO.
14. The method of claim 1 , wherein the posterior ocular disorder or condition is uveitis.
15. The method of claim 1 , wherein the eye of the subject is substantially free of infection.
