Under the terms of the license agreement, RAPT is granted worldwide rights excluding mainland China, Hong Kong, Macau and Taiwan (together, the "Jemincare Territory") to develop and commercialize RPT904. As consideration for the license, Jemincare receives a $35 million upfront license fee, up to $672.5 million in additional payments upon the achievement of various regulatory and commercial milestones, and royalties on future sales of RPT904 outside the Jemincare Territory. RPT904 is being developed to offer patients a potentially improved therapeutic option compared to omalizumab (marketed as Xolair ® ), an anti-IgE monoclonal antibody approved for several allergic disorders, including asthma, chronic spontaneous urticaria (CSU), chronic rhinosinusitis with nasal polyps and, most recently, food allergy. RAPT plans to pursue development of RPT904 initially in food allergy.
