Active Biotech's Prostate Cancer Project TASQ Featured in British Journal of Cancer


Lund, Sweden, September 25, 2009- British Journal of Cancer (doi:
10.1038/sj.bjc.6605322) releases an article covering Active Biotech's
(NASDAQ OMX Nordic: ACTI) prostate cancer project TASQ, where TASQ
was studied as a single agent in patients with castration-resistant
prostate cancer.

Two  open-label   phase   I   clinical  trials   in   patients   with
castration-resistant prostate cancer were  conducted to evaluate  the
safety and tolerability of TASQ, with additional pharmacokinetic  and
efficacy assessments.

The results showed that  long-term continuous oral administration  of
TASQ seems to be safe, and the overall efficacy results indicate that
TASQ might delay disease progression.

A total of 32 patients were enrolled; 21 patients were maintained for
>=4 months. The median PSA progression-free time was 19 weeks. In  15
patients, radiologic imaging with bone scan was done at screening and
every 2 months until the final visit. It is noteworthy that there was
no finding of bone  scan progression at  end of study  in 80% of  the
patients (median treatment time 34 weeks; range 15 - 54 weeks).

TASQ is  presently in  development for  the treatment  of  metastatic
castration-resistant prostate  cancer. A  phase II  study, which  has
completed enrollment of over 200 patients, is currently ongoing.  The
results from this study are expected in late 2009/early 2010.

Notes to editors

About TASQ
The development of TASQ  is principally focused  on the treatment  of
prostate cancer. TASQ is an antiangiogenic compound, meaning that  it
cuts off the supply of nutrients to the tumor but it does not  belong
to the most frequently occurring group of tyrosine kinase inhibitors.
Positive results for the concluded Phase  I trial  show that TASQ  is
well-tolerated and has a favorable safety profile. In September 2008,
the follow-up  efficacy data  from the  Phase Ib  trial of  TASQ  was
presented, which showed that patients treated with TASQ developed few
new bone metastases and displayed a  reduced rate of increase of  the
disease  marker  PSA  (Prostate-Specific  Antigen).  The  project  is
currently in a clinical Phase II trial in progress in the US,  Canada
and  Sweden.  The   trial  is  a   2:1  random,   placebo-controlled,
double-blind study of 1mg/day TASQ, compared with placebo. The  study
includes symptom-free patients  with metastasized,  hormone-resistant
prostate cancer.  Information about  the  ongoing clinical  trial  is
available at www.activebiotech.com and www.clinicaltrials.gov.
