Alexion And Complement Pharma Announce Partnership To Co-Develop Pre-Clinical Complement Inhibitor For Neurodegenerative Disorders

Tuesday, June 12, 2018

Alexion Pharmaceuticals, Inc. and Complement Pharma today announced a partnership to co-develop the preclinical C6 complement inhibitor CP010 for neurodegenerative disorders. C6 inhibition prevents the formation of the destructive membrane attack complex (MAC), a complex of terminal complement proteins that mediate cellular injury following complement activation, and has the potential to treat a variety of central nervous system disorders. Under the terms of the agreement, Alexion will provide Complement Pharma with up to € 14 million in milestone-dependent payments through Phase 1b development. The agreement also provides Alexion with the option to acquire Complement Pharma during the term of the agreement.

“Alexion has been a pioneer in complement biology since the development of Soliris, the world’s first complement inhibitor, which has demonstrated the significant impact that C5 inhibition can have on several diseases caused by uncontrolled complement activation,” said John Orloff, M.D., Executive Vice President and Head of Research & Development at Alexion. “This collaboration provides an exciting opportunity to expand on our more than two decades of complement expertise to potentially treat additional diseases by targeting C6, a different component of the complement system.”

“Our understanding of the role of complement in many disorders continues to increase and many neurodegenerative diseases show activation of the complement system, even in early stages of disease,” said Frank Baas, M.D., Ph.D., Chief Scientific Officer at Complement Pharma. “We believe that C6 inhibition has the potential to treat multiple neurodegenerative disorders, and we look forward to working with Alexion, a partner with a worldwide leading position in complement biology, to realize the possibilities of this approach.”

Under the terms of the agreement, Alexion and Complement Pharma will collaborate on the development program for CP010. Complement Pharma will be responsible for conducting preclinical and Phase 1 studies and for manufacturing CP010. The phased agreement extends through the completion of Phase 1b development. Alexion has the option to acquire Complement Pharma during the term of the agreement.

CP010 is a humanized monoclonal antibody in preclinical development that binds to C6 in circulation to inhibit its function throughout the body by preventing MAC formation in both the periphery and the central nervous system. An end product of the activated complement cascade, MAC has been shown to play a role in neurodegeneration. CP010 has demonstrated C6 inhibition in vitro and in vivo; C6 inhibition prevents the formation of the MAC following complement activation which may allow treatment of a variety of central nervous system disorders.
