Ophthotech Announces First Patient Dosed in Zimura® Phase 2/3 Study to Evaluate Treatment in Patients with Geographic Atrophy, an Advanced Form of Dry Age-Related Macular Degeneration

NEW YORK–(BUSINESS WIRE)–Ophthotech Corporation (Nasdaq:OPHT) announced that the first patient
has been dosed in a Phase 2/3 clinical study of Zimura® (avacincaptad
pegol sodium), an inhibitor of complement factor C5, in patients with
geographic atrophy, an advanced form of dry age-related macular
degeneration (AMD). Complement factor C5 is a central component of the
complement cascade believed to be involved in the development of AMD.
The Phase 2/3 randomized, double-masked, controlled trial is designed to
evaluate the safety and efficacy of Zimura® monotherapy in
patients with geographic atrophy. The Company has also recently
announced the initiation of a Phase 2 study of Zimura® in
combination with anti-VEGF therapy in wet AMD patients to potentially
reduce the treatment burden.

“Dry age-related macular degeneration continues to be a significant
unmet medical need globally with no approved treatment options available
to patients,” said David R. Guyer, M.D., Chief Executive Officer and
Chairman of the Board of Ophthotech. “Multiple published studies suggest
that the complement pathway has a central role in dry AMD. We plan to
explore the potential of Zimura® as a treatment for
geographic atrophy. In addition, the emerging strength of science from
published independent genetic variation studies relating to the role of
complement inhibition in wet AMD along with our earlier Zimura®
study results in wet AMD are encouraging. We are therefore pleased to
have recently announced the initiation of a wet AMD treatment burden
reduction study of Zimura® combination therapy. These are
important milestones for Ophthotech as our effort to develop therapies
to treat underserved populations in all forms of AMD continues to
