Catalyst has developed and optimized a propriety method to create novel proteases that include anti-C3 protease assets such as CB 2782 for ischemia-reperfusion injury such as delayed graft function (DGF) after kidney transplantation and the preclinical leads in the dry age-related macular degeneration (AMD) program. In 2016, Catalyst reduced resources deployed towards its anti-complement research programs and all related research activities were discontinued. These assets are available for partnering.

The complement cascade is a series of molecular processes that plays a central role in the body’s inflammatory and immune responses and helps to localize specific immune system cells at the site of infection or inflammation. Drugs that target the complement cascade could potentially be used in a number of indications, including prevention of transplant rejection, age-related macular degeneration, cardiovascular disease, pulmonary diseases, and autoimmune disease.

CB 2782 is a novel protease derived from human membrane type serine protease 1 (MTSP-1) that cleaves complement factor 3 (C3) and may be developed to prevent delayed graft function (DGF) following kidney transplant as a result of ischemia-reperfusion injury. Other opportunities might include coronary artery bypass graft (CABG), acute myocardial infarction (AMI), and stroke. Catalyst also has earlier stage, distinct anti-complement lead molecules for dry age-related macular degeneration (dry AMD) and other chronic, and selected orphan, diseases.
