Ophthotech Completes Patient Recruitment in Phase 3 Trial of Fovista® Anti-PDGF Therapy in Combination with Eylea® or Avastin® in Wet Age-Related Macular Degeneration

– $30 Million Milestone Triggered by Reaching Final Enrollment Goal
in the Third Phase 3 Trial in the Fovista
Program –

NEW YORK–(BUSINESS WIRE)–Ophthotech Corporation (Nasdaq: OPHT) today announced the completion of
patient recruitment in its Phase 3 trial of Fovista®
(pegpleranib), anti-PDGF therapy, in combination with Eylea®
(aflibercept) or Avastin® (bevacizumab) for the treatment of
wet age-related macular degeneration (AMD). Ophthotech also announced
that it has achieved a $30 million enrollment milestone from Novartis
Pharma AG as part of the ex-US licensing and commercialization agreement
between the two companies focused on the treatment of wet AMD.

The Fovista® Phase 3 program consists of three clinical
trials to evaluate the safety and efficacy of Fovista® in
combination with multiple anti-VEGF agents for the treatment of wet AMD.
The Company completed enrollment in its two other Phase 3 trials of
Fovista® in combination with Lucentis®
(ranibizumab) last year, and expects to announce initial, topline data
from these two studies in the fourth quarter of this year.

“We are thankful for the steadfast commitment of the participating
clinical investigators and their staff for their diligent effort to
complete the enrollment of our Phase 3 trials. We are excited by the
potential of Fovista to be paired with all anti-VEGF agents to address
the growing unmet need for wet AMD patients,” said Samir C. Patel, M.D.,
President and Vice Chairman of the Board of Ophthotech.

The FDA granted Fast Track status for Fovista® for the
treatment of wet AMD in September 2013. The Company believes Fovista®
is the most advanced anti-PDGF agent in development for the treatment of
wet AMD and, if approved, is expected to be first to market in this
class of novel therapies for wet AMD.

The third and final recruitment milestone from the Company’s ex-US
partner for Fovista®, Novartis Pharma AG, was triggered as a
result of Ophthotech reaching this patient enrollment goal. To date,
Ophthotech has attained $330 million in upfront fees and milestone
payments from Novartis. These amounts consist of a $200 million upfront
fee upon the execution of the agreement in May 2014 and $130 million in
enrollment-based milestones under the agreement. Additionally,
Ophthotech is eligible to receive up to an aggregate of $300 million
upon achievement of specified regulatory milestones, including marketing
approval and reimbursement approval in certain ex-US territories, and
ex-US sales milestones of up to $400 million. In addition, Ophthotech is
entitled to receive royalties on ex-US Fovista® sales.

The $30 million milestone will result in approximately $27.0 million of
revenue to be recorded in the quarter ending June 30, 2016. The
remaining $3.0 million will be deferred and recognized as revenue on a
proportional basis through 2018.
