During the first half of 2009 Santaris Pharma continued to make satisfactory
progress in its research and development programs within miRNA, metabolic
disorders and infectious diseases. Key milestones achieved and other events
during the quarter are summarized below.

Development

SPC3649-HCV

SPC3649 is a potent and specific inhibitor of microRNA-122 known to be involved
in cholesterol metabolism and in hepatitis virus replication in the liver. In
April 2009, Santaris Pharma completed a Phase I First-in-Man single dose study
of SPC3649 with 60 healthy volunteers and the Company expects to publicize the
encouraging results of this study in the 2nd half of the year. An IND regarding
a Phase I multiple dose clinical study with SPC3649 in healthy volunteers has
been submitted and the trial is scheduled to be commenced later in 2009. Further
a three months tox study will be initiated during the 2nd half of 2009.

EZN2968-HIF-1alpha

Santaris Pharma’s collaboration partner Enzon Pharmaceuticals announced
preliminary results of the jointly developed Hif-1alpha inhibitor targeting
solid tumors at the AACR meeting in May. Enzon expects to report the results of
its phase I clinical trials targeting solid tumors with EZN2968 in the 2nd half
of 2009. Further Enzon has announced its intention of initiation of a phase II
trial with this compound later in 2009.

SPC2996-CLL

In accordance with Santaris Pharma’s refocusing of own development
activities within metabolic disorders and infectious diseases, it has been
decided to divest the activities within the development of SPC2996 targeting
CLL. This process is ongoing.

EZN3042-Survivin

In February 2009 Santaris Pharma’s collaboration partner Enzon
Pharmaceuticals initiated a phase I clinical trial in solid tumors with the
LNA-based drug Survivin targeting cancer.

SPC4955-ApoB inhibitor

Santaris Pharma has in rodent and primate studies shown that ApoB inhibitors
are able to lower LDL cholesterol and triglycerides effectively. In Q2 2009 the
Company selected a lead candidate SPC4955 for preclinical development.

PCSK9-inhibitors

Santaris Pharma has selected lead candidates targeting PCSK9 related to high
cholesterol. These candidates are ready for pharmacological studies.

Collaborations

Santaris Pharma has collaboration agreements with three partners, covering up
to 22 novel LNA-based RNA therapeutics:

Wyeth Pharmaceuticals (December 2008)

By the end of 2008 Santaris Pharma entered into an agreement with Wyeth
Pharmaceuticals, covering 10 LNA-based drug candidates targeting various
diseases selected by Wyeth. Under the terms of the collaboration Santaris Pharma
will design and generate the drug compounds and Wyeth will be responsible for
all preclinical- and clinical development as well as the commercialization on a
worldwide basis.

GlaxoSmithKline Collaboration (December 2007)

Under the terms of the collaboration with GlaxoSmithKline (GSK) on new drugs
for the treatment of viral diseases, Santaris Pharma is responsible for the
discovery and development of RNA inhibiting drug candidates through to
completion of Phase IIa (Clinical Proof of Concept) for four viral targets, at
which point GlaxoSmithKline will have an exclusive option to license each
compound for further development and commercialisation on a worldwide basis.
Presently GSK has selected one viral disease target and Santaris Pharma has
identified several strong drug candidates against the target.

Enzon Collaboration (August 2006)

Under the terms of the collaboration with Enzon Pharmaceuticals, Santaris
Pharma will design and generate a total of eight drug candidates and Enzon will
fund and manage the preclinical- and clinical development of the drug candidates
and file for regulatory approvals outside Europe. Santaris Pharma has maintained
all commercial rights for the eight drug candidates in Europe.

Enzon is expected to disclose final results from the clinical development of
EZN/SPC2968, a HIF-1alpha inhibitor, which is currently being evaluated in two
separate Phase I/II clinical trials in patients with advanced solid tumors, in
the 2nd half of 2009.

Enzon has initiated a Phase I study in various solid tumors for EZN/SPC3042,
the Survivin inhibitor, in the 1st quarter of 2009.

In addition to EZN/SPC2968 and EZN/SPC3042 Enzon has now received all the
remaining six novel cancer drug candidates from Santaris Pharma and Enzon has
announced the targets for four of these compounds: Her3, beta catenin, PIK3CA
and the androgen receptor.

Pipeline Summary

In H1 2009 Santaris Pharma continued the progress for both the drug discovery
programs and the drug development pipeline. At the end of June Santaris Pharma
had four drugs in clinical development:

- SPC3649, an LNA-antimiR(R) against microRNA-122, being developed for the
treatment of HCV infections - EZN/SPC2968, a HIF-1alpha inhibitor, being
developed for the treatment of various solid tumors - SPC2996, a Bcl-2
inhibitor, being developed for the treatment of cancer. Santaris Pharma has
initiated the process of divesting this candidate - EZN3042, an LNA-based
Survivin inhibitor, being developed for the treatment of various solid tumors

In addition to the four clinical development stage compounds Santaris Pharma
and its partners have several other compounds in the discovery, research and
preclinical stages, including the new apoB inhibitor, SPC4955 which now enters
preclinical development and the PCSK9 lead candidates which are ready for
pharmacological studies.
