Replicor Discloses Late Breaking HBV and Follow-Up HBV / HDV Clinical Data at AASLD 2016

MONTREAL–(BUSINESS WIRE)– Replicor Inc., a privately held biopharmaceutical company targeting a
cure for chronic hepatitis B and D patients, today presented its
preliminary interim analysis from its latest REP 401 clinical trial at
the American Association for the Study of Liver Disease (AASLD) during
the late-breaking oral abstract session at its annual meeting held
November 11-15, 2016 in Boston, U.S.A.,

The REP 401 protocol (NCT02565719)
is a randomized, controlled trial assessing the safety and efficacy of
its first in class HBsAg release inhibitor, REP 2139 and a REP 2139
derivative with improved plasma and tissue clearance (REP 2165) in
combination with tenofovir disoproxil fumarate (TDF) and pegylated
interferon alpha-2a (peg-IFN) in treatment naïve patients with chronic
HBeAg negative HBV infection.

Control patients receiving peg-IFN + TDF exhibited minimal antiviral
response beyond suppression of serum HBV DNA. Patients receiving REP
2139 or REP 2139 in addition to peg-IFN and TDF experienced robust,
multilog reductions in HBsAg, increased levels of circulating anti-HBsAg
antibodies and serum transaminase flares indicating restored immune
response in the liver.

Replicor also presented its complete 6 month follow-up data from the REP
301 protocol (NCT02233075)
assessing the safety and efficacy of REP 2139 in combination with
peg-IFN in patients with chronic HBV / HDV co-infection. After 24 weeks
of follow-up, despite the use of a suboptimal combination regimen, 5/12
patients had no detectable HBsAg and 7/12 patients had no detectable HDV
RNA, indicating that functional control of infection has been
established in these patients.

These presentations confirm Replicor’s previous proof of concept
clinical trial data and demonstrate that its nucleic acid polymer
technology has a unique ability to clear serum HBsAg, substantially
improve antiviral response to immunotherapy and to achieve functional
cure of both HBV and HDV infection.

Replicor’s presentations from AASLD 2016 will be available on the
company’s website following their disclosure at the meeting at www.replicor.com/science/conference-presentations.
