Under these agreements, Biocytogen will provide fully human antibodies developed using its proprietary mice platforms to the Licensees for evaluation and grant the Licensees an option to acquire a worldwide license in respect of the subsequent development, manufacturing and commercialization of the selected antibodies. Biocytogen will receive an upfront payment, an option exercise fee, ongoing development and commercialization milestone payments, as well as royalties on net sales.

Among those Licensees, Pheon Therapeutics is a U.K. ADC specialist developing a pipeline of monotherapies for novel targets and/or with novel payloads; Myricx Bio is a U.K. biotech company focused on the discovery and development of a completely novel class of selective cytotoxic payloads for ADCs; Ona Therapeutics is a Spanish biotech company that specializes in unravelling novel biology to design first-in-class biopharmaceuticals that attack advanced cancer; and Neurocrine Biosciences is a U.S. biopharmaceutical company committed to the discovery and development of therapies for neurological, neuroendocrine and neuropsychiatric diseases.
