  • Patent number: 11883525
    Abstract: The present disclosure provides compositions that enable sustained release of a small molecule tyrosine kinase inhibitor, such as axitinib from a bioerodible polyester polymer implant for the treatment of disease. The composition is especially suitable for treating ophthalmic indications, such as neovascular age related macular degeneration and diabetic macular edema, by intravitreal injection of the implant. The implant is designed to be pre-loaded into a small diameter needle and injected via self-sealing scleral needle penetration at the pars plana. Small molecule tyrosine kinase inhibitors may be released from the implants over a period of one week to three years.

  • Patent number: 9789001
    Abstract: Implants and methods for treating ocular disorders are provided. One method involves introducing an implant into an anterior chamber of an eye. The implant is implanted into eye tissue adjacent the anterior chamber such that a proximal end of the implant resides in the anterior chamber following implantation. A therapeutic agent is eluted from the implant into the eye. Desirably, the release of the therapeutic agent from the implant is controlled. The controlled release of the therapeutic agent can be at a chosen rate and/or for a selected duration which can be episodic or periodic. The therapeutic agent can be an antiproliferative agent, an anti-inflammatory drug, or a compound for treating glaucoma or ocular hypertension.
