Ardana PLC21 November 2007 ARDANA ANNOUNCES POSITIVE PRELIMINARY RESULTS IN A FURTHER PHASE II STUDY OF TEVERELIX LA IN BENIGN PROSTATIC HYPERPLASIA Edinburgh, UK, 21 November 2007: Ardana plc (LSE:ARA) today announces positivepreliminary results from a Phase II study of its key compound, the GnRHantagonist Teverelix Long Acting (LA), which shows that patients may only needto have two maintenance doses per year to treat the symptoms of benign prostatichyperplasia (BPH), a significant potential improvement over current treatments. In previous clinical studies in BPH, Teverelix LA has been shown to decreasetestosterone and subsequently dihydrotestosterone (DHT) in a dose-dependentmanner to levels at the low end of the normal range thereby avoiding a chemicalcastration and its related symptoms. In two earlier Phase II studies in patientswith BPH, Teverelix LA demonstrated an improvement in symptoms of BPH asmeasured by the International Prostate Symptom Score (IPSS). This effect wasshown as early as two weeks after dosing. This latest study is a Phase II, randomised, double-blind, placebo-controlledfollow-on study investigating the effects of Teverelix LA when administered as asecond single subcutaneous injection to patients with BPH who had completed aprior clinical study. The subjects received the same high or low dose ofTeverelix or placebo as they had received in the previous study and weremonitored at four weekly intervals up to 28 weeks after the second injection. Ofthe 84 subjects enrolled in the previous study, 77 were enrolled in this studyand 48 completed the study 28 weeks later. The effects of Teverelix LA on IPSS in this BPH study were marked and sustainedand both clinically and statistically significant. Following study druginjection, the mean IPSS was reduced in all three groups (placebo; low doseTeverelix; high dose Teverelix). At two weeks following the second injection themean changes were -0.9; -2.4 and -2.0 respectively. The maximal effect on IPSSwas observed in all groups 28 weeks after dosing. The mean reductions were -2.6;-4.5 and -5.4 respectively where a reduction in the score by greater than 4 isdeemed to be a highly clinically significant improvement. These changes werestatistically significant in both the active groups (p=0.042 and 0.012respectively). Dr Huw Jones, Ardana's CEO said: "Once again Teverelix LA has shown to deliverimpressive results in the clinic. This repeat dose study shows a clinicallyrelevant improvement in symptoms as measured by the IPSS results. It alsoindicates that BPH sufferers may only need two maintenance doses a year to keeptheir benign prostate disease under control and improve their symptoms." BPH is a common benign disease occurring in men over the age of 50 and increasesin prevalence with age. BPH is characterised by an enlargement of the prostategland, which results in urinary flow problems such as hesitancy, weak orinterrupted stream, urgency and more frequent urination, especially at night. The growth of prostatic tissue is driven by male sex hormones (known asandrogens), primarily testosterone and its more potent metabolitedihydrotestosterone (DHT). Reducing levels of these hormones can reduce thesize and growth of the prostate and thus help improve symptoms. Current treatment options for patients with BPH include watchful waiting,surgical or endoscopic treatment or medical treatment with 5-alpha reductaseinhibitors or alpha blockers. The BPH pharmaceutical market is estimated to beworth US$4.9 billion in 2005 (Source: Wood Mackenzie - Product View April 2006).
