OvaScience Provides Update on Corporate Goal for AUGMENT Treatment

CAMBRIDGE, Mass.–(BUSINESS WIRE)–OvaScienceSM (NASDAQ: OVAS), a global fertility company
focused on the discovery, development and commercialization of new
treatment options, today announced that the Company does not expect to
meet the 2015 goal of 1,000 AUGMENTSM treatment cycles. The
AUGMENT treatment patient experience has been positive and OvaScience
has built strong technical operations, quality and manufacturing;
however, the Company is continuing to enhance its commercial operations
and infrastructure to optimize for commercial success. In addition,
evolving market dynamics in the fertility space, including recent merger
and acquisition activities at the key commercial IVF clinics where the
AUGMENT treatment is offered, have hindered the Company’s ability to
drive major volume that was anticipated in the fourth quarter.

Michelle Dipp, M.D., Ph.D., Chief Executive Officer of OvaScience,
stated, “We are adapting our regional commercial operations and
infrastructure as well as addressing an even more dynamic global IVF
landscape. In addition, we recently became aware of M&A activities in
our key clinics. We believe these factors will prevent us from achieving
our goal as we had anticipated the majority of AUGMENT treatment cycles
would initiate in the fourth quarter. While disappointing in the
short-term, the expanding clinic networks may enable more patients to
have access to the AUGMENT treatment. With the positive patient
experience to date, including multiple healthy births, we remain
confident in the commercial potential of the AUGMENT treatment and our
future fertility treatments.”

The Company established 2015 as a build year and made significant
advances in key areas:

  • Achieved quality and scalability of its global manufacturing and
    technical operations;
  • Published positive patient experiences, including the birth of ten
    healthy babies, and will continue to demonstrate the clinical benefit
    of the AUGMENT treatment by capturing additional data in its
    international patient registry;
  • Formed new clinic partnerships, including with the IVI Group, the
    largest IVF clinic network in the world; and
  • Advanced plans to introduce the AUGMENT treatment in Japan and the
    United Kingdom.

Goals for the OvaPrimeSM and OvaTureSM treatments
remain on track for 2015, with plans to introduce the OvaPrime treatment
in patients outside of the United States and to communicate the
Company’s development strategy for the OvaTure treatment.

About OvaScience

OvaScience (NASDAQ: OVAS) is a global fertility company dedicated to
improving treatment options for women around the world. OvaScience is
discovering, developing and commercializing new fertility treatments
because we believe women deserve more options. Each OvaScience treatment
is based on the Company’s proprietary technology platform that leverages
the breakthrough discovery of egg precursor (EggPCSM) cells –
immature egg cells found inside the protective ovarian lining. The
AUGMENTSM treatment, a fertility option specifically designed
to improve egg health, is available in certain IVF clinics in select
international regions outside of the United States. OvaScience is
developing the OvaPrimeSM treatment, which could increase a
woman’s egg reserve, and the OvaTureSM treatment, a potential
next-generation IVF treatment that could help a woman produce healthy,
young, fertilizable eggs without hormone injections. For more

launched or plan to introduce the AUGMENT treatment and plan to
introduce the OvaPrime treatment; the commercial ramp up of the AUGMENT
treatment; the science underlying our treatment and treatments in
