77 results about "Complement inhibitor" patented technology

Complement Inhibitors. Complement inhibitors are a type of monoclonal antibody that are used to treat paroxysmal nocturnal hemoglobinuria (PNH) and atypical hemolytic uremic syndrome (aHUS). They prevent a part of the immune system from harming healthy cells and tissue.

Targeted and high density drug loaded polymeric materials

Polymeric delivery devices have been developed which combine high loading / high density of molecules to be delivered with the option of targeting. As used herein, “high density” refers to microparticles having a high density of ligands or coupling agents, which is in the range of 1000-10,000,000, more preferably between 10,000 and 1,000,000 ligands per square micron of microparticle surface area. A general method for incorporating molecules into the surface of biocompatible polymers using materials with an HLB of less than 10, more preferably less than 5, such as fatty acids, has been developed. Because of its ease, generality and flexibility, this method has widespread utility in modifying the surface of polymeric materials for applications in drug delivery and tissue engineering, as well other other fields. Targeted polymeric microparticles have also been developed which encapsulate therapeutic compounds such as drugs, cellular materials or components, and antigens, and have targeting ligands directly bound to the microparticle surface. Preferred applications include use in tissue engineering matrices, wound dressings, bone repair or regeneration materials, and other applications where the microparticles are retained at the site of application or implantation. Another preferred application is in the use of microparticles to deliver anti-proliferative agents to the lining of blood vessels following angioplasty, transplantation or bypass surgery to prevent or decrease restenosis, and in cancer therapy. In still another application, the microparticles are used to treat or prevent macular degeneration when administered to the eye, where agents such as complement inhibitors are administered.

Methods of preventing and treating Alzheimer's disease, age related macular degeneration and other diseases involving extra-cellular debris through the inhibition of the complement system

This invention proposes that the best therapeutic strategy for treating and / or preventing Alzheimer's disease (AD), age related macular degeneration (AMD) and other diseases that exhibit extra-cellular debris deposits, such as atherosclerosis, is the inhibition of the complement pathway. A model for the accumulation of extra-cellular debris through the activation of the complement pathway is presented, and the primary pathogenic role of the debris in the etiology of the disorders is explained. Previously identified complement inhibitors are identified as therapeutic agents for the treatment and / or prevention of AD, AMD and other diseases that exhibit extra-cellular debris deposits.

Tissue targeted complement modulators

Systemic suppression of the complement system has been shown to be effective to treat inflammatory disease, yet at the potential cost of compromising host defense and immune homeostasis. Herein disclosed are methods for antigen-specific targeting of complement inhibitors that show that complement inhibitors targeted to the proximal tubular epithelium protect against tubulointerstitial injury and renal dysfunction in a rat model of nephrosis. It is shown that appropriate targeting of a systemically administered complement inhibitor to a site of disease markedy enhances efficacy and obviates the need to systemically inhibit complement. Additionally, it is shown by specifically inhibiting the terminal pathway of complement, that the membrane attack complex (MAC) plays a key role in proteinuria-induced tubulointerstitial injury, thus establishing the MAC as a valid target for pharmacological intervention in proteinuric disorders. The disclosed are compositions can be used in methods of treating pathogenic diseases and inflammatory conditions by modulating the complement system.

Risk evaluation and management strategy involving patient follow-ups relating to the use or discontinuation of a complement inhibitor

This invention provides, inter alia, a complement-inhibitor-based treatment plan coupled with a risk evaluation and management strategy (“REMS”) and a safety support program (“SSP”) for reinforcing the REMS. The REMS and SPP are implemented using one or more computer devices with software tools programmed to enforce conditions of the REMS and / or prompt follow-ups by registered nurses enrolled in the SSP. The software tool(s) determines whether a prescriber requesting the complement inhibitor has agreed to abide by the REMS, and can prompt a provider of the complement inhibitor to provide updated educational materials to the prescriber at predetermined times or intervals, to monitor the prescriber for compliance with the REMS, and / or to monitor patients for signs of adverse events. Using exemplary embodiments described herein, a risk of adverse events (especially, but not limited to, meningococcal infections) can be managed and an incidence of the adverse events can be reduced.
