  • Publication number: 20250041485
    Abstract: The present disclosure is directed to a composite implant for the sustained release of a therapeutic agent from a hydrogel matrix. The hydrogel matrix may be a cross-linked bioerodible polyethylene glycol (PEG) hydrogel with a therapeutic complex dispersed within the cross-linked bioerodible PEG hydrogel. The therapeutic complex may include a therapeutic agent in association with mesoporous silica particles. The composite implant is configured to be delivered to or implanted into an eye of a subject or patient. The composite implant may be used treat ocular disease in a subject or patient. Ocular diseases may be selected from at least one of neovascular age related macular degeneration (AMD), diabetic macular edema, or macular edema following retinal vein occlusion.

  • Publication number: 20240165017
    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: 5881135
    Abstract: A service platform provides automated speech based services over a telephone network. It includes a speech processor with associated memory, to provide services such as speech recognition, speaker recognition, speaker verification and speech synthesis. A line interface terminates a number of telephony channels of the network while a speech bus carries speech signals between the line interface and the speech processor. A control processor controls routing of speech signals over the speech bus and a control bus connects the control processor with the speech processor and the line interface. A separate memory holds speech processing software and a data link connects the memory with the speech processor to load programs into the speech processor during run time in the event that appropriate software does not exist on the speech processor in a free state.
