Omeros Corporation Announces Upcoming Educational Event at the Annual Meeting of the European Society of Blood and Marrow Transplantation
Session Will Focus on Diagnosis of Hematopoietic Stem Cell Transplant-Associated Thrombotic Microangiopathy
SEATTLE--(BUSINESS WIRE)-- Omeros Corporation (Nasdaq: OMER) today announced an upcoming educational event at the 2019 Annual Meeting of the European Society of Blood and Marrow Transplantation to be held in Frankfurt, Germany on March 24-27, 2019. Sponsored by Omeros, the educational session entitled “How Do I … Diagnose HSCT-TMA” will be held on Tuesday, March 26, at 2:00-3:30 PM local time. There is growing recognition that hematopoietic stem-cell transplant-associated thrombotic microangiopathy (HSCT-TMA), a potentially lethal complication of stem-cell transplants, is underdiagnosed in the U.S. and worldwide. A study from the Dana Farber Cancer Institute reported that, while 39% of patients receiving allogeneic HSCT developed TMA, the disorder was often unrecognized during clinical care.
The session, conducted by an international panel of experts, will focus on the diagnosis of HSCT-TMA and on the relationship between HSCT-TMA and the broader syndrome of disorders caused by endothelial injury. In addition to TMA, endothelial injury is associated with several complications of HSCT, including graft-versus-host disease, veno-occlusive disease, and diffuse alveolar hemorrhage. Narsoplimab, Omeros’ antibody to inhibit the lectin pathway of complement, has received breakthrough therapy designation from FDA and is in Phase 3 development for the treatment of HSCT-TMA.
About Omeros’ MASP Programs
Omeros controls the worldwide rights to MASP-2 and all therapeutics targeting MASP-2, a novel pro-inflammatory protein target involved in activation of the complement system, which is an important component of the immune system. The complement system plays a role in the inflammatory response and becomes activated as a result of tissue damage or microbial infection. MASP-2 is the effector enzyme of the lectin pathway, one of the principal complement activation pathways. Importantly, inhibition of MASP-2 does not appear to interfere with the antibody-dependent classical complement activation pathway, which is a critical component of the acquired immune response to infection, and its abnormal function is associated with a wide range of autoimmune disorders. MASP-2 is generated by the liver and is then released into circulation. Gene-targeted MASP-2-deficient mice and humans with MASP-2 gene polymorphisms that affect MASP-2 serum levels and MASP-2 functional activity are generally healthy with no obvious adverse phenotype.
Phase 3 clinical programs are in progress for narsoplimab, Omeros’ lead MASP-2 inhibitor also referred to as “OMS721,” in hematopoietic stem cell transplant-associated thrombotic microangiopathy (HSCT-TMA), in immunoglobulin A (IgA) nephropathy, and in atypical hemolytic uremic syndrome (aHUS). Narsoplimab can be administered both intravenously and subcutaneously, and Omeros expects to commercialize each formulation of narsoplimab for different therapeutic indications. In parallel, Omeros is developing small-molecule inhibitors of MASP-2. Based on requests from treating physicians, Omeros has established a compassionate-use program for narsoplimab, which is active in both the U.S. and Europe. The FDA has granted narsoplimab breakthrough therapy designation for IgA nephropathy and for HSCT-TMA, orphan drug status for the prevention (inhibition) of complement-mediated thrombotic microangiopathies, for the treatment of IgA nephropathy, for the treatment of HSCT-TMA, and fast track designation for the treatment of patients with aHUS. The European Medicines Agency has granted orphan drug designation to narsoplimab for treatment of primary IgA nephropathy and for treatment in HSCT.
Omeros also has identified MASP-3 as responsible for the conversion of pro-factor D to factor D and as a critical activator of the human complement system’s alternative pathway. The alternative pathway is linked to a wide range of immune-related disorders. In addition to its lectin pathway inhibitors, the company is advancing its development of antibodies and small-molecule inhibitors against MASP-3 to block activation of the alternative pathway. Omeros has initiated the manufacturing scale-up process of its MASP-3 antibodies in preparation for clinical trials.
About Omeros Corporation
Omeros is a commercial-stage biopharmaceutical company committed to discovering, developing and commercializing small-molecule and protein therapeutics for large-market as well as orphan indications targeting inflammation, complement-mediated diseases, disorders of the central nervous system and immune-related diseases, including cancers. The company’s drug product OMIDRIA (phenylephrine and ketorolac intraocular solution) 1% / 0.3% is marketed for use during cataract surgery or intraocular lens (IOL) replacement to maintain pupil size by preventing intraoperative miosis (pupil constriction) and to reduce postoperative ocular pain. In the European Union, the European Commission has approved OMIDRIA for use in cataract surgery and other IOL replacement procedures to maintain mydriasis (pupil dilation), prevent miosis (pupil constriction), and to reduce postoperative eye pain. Omeros has multiple Phase 3 and Phase 2 clinical-stage development programs focused on: complement-associated thrombotic microangiopathies; complement-mediated glomerulonephropathies; cognitive impairment; and addictive and compulsive disorders. In addition, Omeros has a diverse group of preclinical programs and a proprietary G protein-coupled receptor (GPCR) platform through which it controls 54 new GPCR drug targets and corresponding compounds, a number of which are in preclinical development. The company also exclusively possesses a novel antibody-generating platform.
