Glenmark Pharmaceuticals Initiates Clinical Investigation for GBR 310, its Proposed Biosimilar Candidate for XOLAIR®

Mumbai, India; April 25, 2017: Glenmark Pharmaceuticals, a global pharmaceutical company, today announced that the U.S. Food and Drug Administration (FDA) cleared the company’s Investigational New Drug (IND) application to initiate a first-in-human study of GBR 310, a proposed biosimilar, which will assess its pharmacokinetics in comparison to XOLAIR® (omalizumab) in healthy adult volunteers between 18 – 65 years of age. “This marks the second IND activation in 2017 for our growing respiratory portfolio,” said Kurt Stoeckli, President and Chief Scientific Officer at Glenmark Pharmaceuticals. “In the seven years since the U.S. approval process for biosimilar medicines was signed into law, there have been few candidates successfully developed. GBR 310 has the potential to be among the first biosimilar candidates to be submitted for approval for a respiratory or allergic disease.” GBR 310 is a recombinant DNA-derived humanized immunoglobulin G1 kappa monoclonal antibody. Its current proposed indication is for the treatment of allergic asthma and chronic idiopathic urticaria. The reference product for GBR 310 is omalizumab, available under the brand name XOLAIR. According to IMS sales data for the 12-month period ending February 2017, annual sales of XOLAIR 150 mg injection was approximately $1.7 Billion in the U.S.1 About Allergic Asthma and Chronic Idiopathic Urticaria Asthma is one of the most common diseases in children and affects more than 18 million people older than 18 in the U.S.2,3 Allergic asthma is unique because it is triggered by exposure to year-round allergens like pet dander and dust mites. Allergies trigger asthma attacks in 60-90 percent of children with asthma and in approximately 50 percent of adults.4 Urticaria is a common skin disease that presents as spontaneously recurring hives or welts. It occurs across all age groups and about one percent of the population suffers from a chronic form of the disease.5 Among this group, 70% of people report symptoms that last for more than one year and 14% report symptoms that last for more than five years.6 About Glenmark’s Respiratory Pipeline Glenmark’s respiratory pipeline is specifically aimed at addressing the global public health burden of allergic rhinitis, asthma, and chronic obstructive pulmonary disease (COPD), and includes four investigational treatments across the disease spectrum and devices.
