Positive clinical data for new prostate cancer treatment
Helsingborg, Sweden March 21st 2011 – LIDDS new local treatment of prostate cancer shows a clear
local antiandrogen response and is well tolerated. The Swedish pharmaceutical company presented
interim data from its phase IIa trial at the 26th Annual Congress of the European Association of
Urology (EAU) in Vienna this weekend.
LIDDS has gained promising data from its Phase IIa study for treatment of localized prostate cancer.
LIDDS´ novel product Liproca® Depot is an injectable modified release product that successfully has
been developed for local antiandrogen therapy of prostate cancer. The company presents the data
at the 26th Annual Congress of the European Association of Urology (EAU) in Vienna. The novel
product has demonstrated effect on an established cancer biomarker and has a very low frequency
of antiandrogen related side-effects. This is accomplished by delivering sufficiently high drug
concentrations in the tumor areas, within the prostate gland, during several months, following one
single injection of Liproca® Depot, while avoiding high systemic drug concentration and thus avoiding
the antiandrogen related side-effects.
Hans Lennernäs, professor in biopharmaceutics at Uppsala University and chief scientific advisor to
LIDDS and one of the inventors says, “It is obvious that there is a place for novel treatments of this
localized stage of the prostate cancer disease. Focal drug therapy with Liproca® Depot is expected to
become an important treatment tool to be used in these patients as it delivers both high degree of
inhibition of cancer growth, low frequency of side-effects and high level of quality of life”
Many of today´s treatment alternatives are far from optimal as they are relatively costly and bring
about many severe side-effects such as impotence, weight gain, muscle strength, osteoporosis and
metabolic changes as increased risk of diabetes and cardiovascular diseases. Several of these sideeffects are caused by the high levels of active drug in the blood. Liproca® Depot is meeting this
unmet need, as none of these unacceptable side-effects are expected by a local treatment in the
prostate tissue, as the systemic drug concentration will be low.
The interim data from the ongoing phase IIa study in patients with prostate cancer confirms the
positive phase I data as well as data from non-clinical studies which strongly indicate that Liproca®
Depot is a product with high positive benefit/ risk ratio. The interim data from the phase IIa trial also
confirms that there is a clear local antiandrogen response and that the treatment is well tolerated.
The Swedish MPA supports further clinical development after reviewing the preliminary results from
this phase IIa trial.

About prostate cancer
Prostate cancer is a hormone-dependent disease that is dependent on endogenous androgens
(testosterone and dihydrotestosterone) to advance and proliferate. In developed countries, prostate
cancer is the second most frequently diagnosed cancer and the third most common cause of death of
cancer in men (although varying from country to country). Estimates in autopsy studies indicate that
50 % of men older than 50 years of age have prostate cancer. Clinically, prostate cancer is diagnosed
as local or advanced, and treatments range from active surveillance to radical local treatment or
androgen-deprivation treatment. More than 90 percent of all prostate cancers are discovered in the
local and regional stage. In Europe and North America about 450 000 new cases are diagnosed
annually and many of them are expected to be possible candidates for treatment with Liproca®
Depot.
