Forward-Looking Statements
This presentation contains, in addition to historical information, forward-looking
statements within the meaning of the Private Securities Litigation Reform Act of 1995.
These statements relate to future events or future financial performance, and use words
such as “may,” “estimate,” “could,” “expect” and others. They are based on our
current expectations and are subject to factors and uncertainties which could cause actual
results to differ materially from those described in the statements. These statements
include those regarding potential therapeutic benefits of our drugs, expectations,
plans and timelines related to our clinical trials, potential partnering opportunities
and estimated spending for 2015. Factors that could cause our actual performance to
differ materially from those discussed in the forward-looking statements include, among
others, our trials may not lead to positive outcomes or regulatory approval. We
may experience delays in our trials, which could include enrollment delays.
Future phases or future clinical studies may not begin or produce positive results in a timely
fashion, if at all, and could prove time consuming and costly. Plans regarding development,
approval and marketing of any of our drugs are subject to change at any time based on
the changing needs of our company as determined by management and regulatory agencies.
Strategies and spending projections may change. We may be unsuccessful in
developing partnerships with other companies or obtaining capital that would allow us to
further develop and/or fund any studies or trials. We are currently the subject of litigation,
which may impact our human and capital resources. To date, we have incurred operating
losses since our inception, and our future success may be impacted by our ability to
manage costs and finance our continuing operations. For a discussion of additional
factors impacting our business, see our Annual Report on Form 10-K for the year ended December 31,
2013, and our subsequent filings with the SEC. You should not place undue reliance on
forward-looking statements. Although subsequent events may cause our views to
change, we disclaim any obligation to update forward-looking statements. |

 •
FibroTest
®
is a composite fibrosis score that is calculated from serum A2M
levels
and four other tests, including GGTP, total bilirubin, haptoglobin and
apolipoprotein A1
•
FibroTest
®
has been shown to correlate with stage of fibrosis, changes with
fibrosis regression and progression, and may predict liver-related
mortality* •
A reduction in FibroTest
®
would suggest an improvement in liver fibrosis
•
In this acute setting, following four doses of 8 mg/kg GR-MD-02, the
reduction in FibroTest
®
is due entirely to reduced serum levels of A2M
•
A2M is a relevant marker for liver fibrosis because it is known to:
•
Inhibit proteases such as collagenase, which may promote fibrosis
•
Is increased in fibrogenic stellate cells in liver fibrosis
•
Serum levels have been shown to correlate with liver fibrosis
•
The reduction seen in A2M does not necessarily mean fibrosis got better in
this short study, but does suggest changes in the fibrogenic process that
might lead to an improvement in fibrosis with longer-term therapy

•
FibroScan uses an
electromechanical vibrator and
pulse-echo ultrasound to evaluate
the elastic shear wave in liver
tissue
•
The volume of liver tissue
assessed is ~100-times greater
than volume assessed by liver
biopsy
•
The stiffness of the liver is
recorded as the pressure
measurement of kiloPascals
•
The stiffness of the liver
correlates with the degree of liver
fibrosis as assessed by liver
biopsy
•
FibroScan represents a promising
non-invasive, out-patient method
for measuring changes in liver
fibrosis over time

*In cohort 3 there were technically adequate scans at baseline, Day 38
and Day 63 in 5 patients administered GR-MD-02 and 3
patients administered placebo. Five patients in cohort 3 were not
available for FibroScan analysis (3 placebo and 2 active) because of
unavailability of the instrument at the site (1 placebo and 1 active),
unavailability of the appropriate instrument probe (1 active), a
technically inadequate baseline scan (1 placebo), and the Day 63 scan
not being performed (1 placebo). ® |
 GR-MD-02 at doses up to 8 mg/kg IV is safe and well tolerated in
NASH patients with advanced fibrosis
A dose of 8 mg/kg IV is in the upper range of the targeted
therapeutic window for drug administration
The combined results of a reduction in serum alpha-2
macroglobulin and a reduction in liver stiffness as assessed by
FibroScan
®
suggests that GR-MD-02 at the highest dose tested
may have an effect on liver fibrosis
In conclusion, these results provide a firm foundation for entry
into a Phase 2 development program
