Diamyd Medical's Phase II study in cancer pain fully recruited


The last study participant has been recruited to Diamyd Medical’s Phase II study
in which cancer pain is treated with the drug candidate NP2 Enkephalin. The
study is thus fully enrolled and results are expected to be reported in five to
seven weeks.
The purpose of the Phase II study is to evaluate NP2 Enkephalin for the
treatment of severe and chronic cancer pain. It is the first sizeable and
placebo-controlled clinical trial of a drug candidate based on Diamyd Medical’s
patented Nerve Targeting Drug Delivery System, a unique technology for delivery
of therapeutics directly to the nervous system.

"After an intense effort to recruit the last few subjects, the Phase II study is
now fully enrolled and we will soon be able to evaluate whether our unique
concept to treat severe pain works also in this larger study," says Peter
Zerhouni, President and CEO of Diamyd Medical. "With the study results we hope
to establish proof of principle for this innovative method to treat pain by
delivering therapeutics directly to the nervous system. If the concept proves
successful, it will provide many new opportunities to treat pain and other
medical problems in the nervous system for which there are currently no
effective treatments available."

The Phase II study comprises approximately 32 subjects with severe cancer pain
and is being conducted at 18 clinics in the United States. It is a multicenter,
placebo controlled, double-blind and randomized study. There is a four-week,
double-blind study period where the subjects’ pain scores are being monitored
and recorded. The first results from the study are expected to be reported in
five to seven weeks. After the four week blinded study period all patients are
offered up to two doses of active NP2 Enkephalin in an unblinded study
extension. The follow-up will collect pain scores following repeat dosing as
well as provide additional safety data.

NP2 Enkephalin is the furthest advanced drug candidate within the NTDDS platform
and delivers the natural painkilling substance enkephalin directly to the
nervous system for the treatment of pain. Substantial and sustained pain relief
has previously been observed in a Phase I study with the purpose to evaluate the
safety of NP2 Enkephalin and the NTDDS platform. The study was designed as a
dose-escalation study with three different doses, comprising ten subjects with
medium to severe cancer pain refractory to maximal doses of pain medication. The
results of the study were presented in the autumn of 2010. No serious side
-effects related to the treatment have been reported by any of the participants
in the study.

About the NTDDS platform
Diamyd Medical’s Nerve Targeting Drug Delivery System (NTDDS) is an innovative
technology for the delivery of therapeutics directly to the nervous system and
forms the basis of the Company’s development projects within pain and
neuropathy. The NTDDS technology aims to provide a local effect in the parts of
the body where the treatment is targeted without affecting the rest of the body.

The NTDDS platform comprises three drug candidates for the treatment of various
forms of chronic pain; NP2 Enkephalin, NG2 GAD, NE2 Endomorphin and one drug
candidate for the prevention of chemotherapy induced peripheral neuropathy, NN1
Neurotrophin.

Diamyd Medical´s NTDDS-based drug candidates consist of a vector which carries a
gene for a therapeutic substance, e.g., a painkilling substance. The drug is
injected into the skin, where the vector and the gene are taken up by nerve
endings and then transported along the body’s peripheral nerve pathways to nerve
cell bodies that lie just outside the spinal cord. Here the nerve cell’s own
processes are being used to continuously produce the therapeutic substance with
the gene as template.

The NTDDS technology is expected to have several advantages over established
therapies. Since NTDDS is gene-based, a single dose can provide a relatively
long-term therapeutic effect that may last several weeks to months. As the
treatment acts locally, a very low amount of the drug may be enough to achieve
the desired effect. Furthermore, systemic drug exposure is limited, a fact that
may significantly reduce the risk of side effects.

The technology has a wide potential and may be used for the treatment of several
different diseases and symptoms in the peripheral and central nervous system
such as chronic pain, neuropathy (nerve damage), cancer and neurodegenerative
diseases. Research and development on the NTDDS platform is primarily carried
out by the subsidiary Diamyd, Inc. located in Pittsburgh, USA.
