CLINICAL DEVELOPMENT OF ARDANA'S TEVERELIX LONG ACTING (LA) IN PROSTATE CANCER
CONTINUES ON TRACK FOLLOWING PRE-IND APPLICATION MEETING WITH THE UNITED STATES
FOOD AND DRUG ADMINISTRATION (FDA)


Edinburgh, UK, 7 September 2005;  Ardana plc (LSE:ARA) the emerging
pharmaceutical company focused on improving human reproductive health, today
announces that the company has had a pre-Investigational New Drug (IND)
application meeting with the FDA to discuss the development for prostate cancer
of its lead compound Teverelix LA, a GnRH antagonist.

Recent results from two Phase II studies in patients with prostate cancer have
been detailed in previous press releases. In these studies Teverelix LA
successfully suppressed serum testosterone to the required levels for treatment.

An additional Phase II study outside the USA is expected to commence within the
coming month and results from this study should be available in the first half
of 2006.

The FDA has confirmed that serum testosterone levels can serve as a reliable
surrogate marker for efficacy in the treatment of prostate cancer.  The meeting
reached agreement on the path forward for the development of Teverelix LA for
the treatment of prostate cancer, which will allow Ardana to meet its
registration timelines and previously announced launch target of the end of
2009.  Ardana is planning to submit to the FDA its first study to be performed
under an IND in the pursuit of this indication within the next few months.

Dr Maureen Lindsay, CEO Ardana, said 'We are very encouraged by the feedback we
have had from the FDA.  The clinical development and launch for prostate cancer
is on track according to our original schedule. Teverelix LA is also being
developed for the treatment of Benign Prostatic Hyperplasia (BPH) and
Endometriosis. We expect to be reporting shortly on a further meeting with the
FDA about BPH. '
