Ardana PLC12 April 2006 ARDANA ANNOUNCES POSITIVE PHASE II RESULTS FOR TESTOSTERONE CREAM -- Company announces Phase II results-- Edinburgh, UK: 12 April 2006: Ardana plc (LSE:ARA) today announces positiveresults of its testosterone cream in a Phase II study in Hypogonadal Men. ThisPhase II dose-finding study provided clear evidence of the effectiveness ofArdana's bi-gel technology for the transdermal delivery of testosterone. The double-blind, randomised, placebo-controlled study involved 42 patientsdiagnosed with confirmed male hypogonadism, i.e. testosterone deficiency. Threegroups, each of 14 patients, received in random order a single application ofthe testosterone cream at a dose of 1.5g, 2.25g or 3.0g, or a placebo cream.Both placebo and active cream were applied to one upper arm only. The data show that maximal serum concentration was achieved between 10 and 12hours after the application. For the three doses, 1.5, 2.25 and 3.0g, theaverage concentrations of testosterone over 24 hours were 2.06, 2.13 and 2.63 ng/ml and the maximal concentrations were 3.35, 3.53 and 5.66 ng/ml respectively. This observed data is consistent with data reported previously. Pharmacokineticmodelling of the data from this study predicts that testosterone can be fullyrestored in hypogonadal men, to within normal range with one of the followingtwo doses; 1.5g or 2.25g, or combinations thereof; when administered on a dailybasis (i.e. at steady state). Ardana has also initiated a further one month Phase II study in hypogonadal men.In this study, steady state conditions of testosterone and longer-termtolerability are being evaluated. A pivotal Phase III registration study isexpected to be completed by end 2006. Ardana's testosterone cream, which is in Phase II of clinical development inEurope, is a stable cream consisting of both an oil and water-based phasetogether with the active ingredient, testosterone. Because of its reducedsurface area requirement, Ardana's testosterone cream appears to delivertestosterone more efficiently than existing gel-based testosterone products andalso has a low alcohol content. Alternative therapies for male hypogonadisminclude injectable formulations of testosterone, oral preparations, transdermalpatches, topical gels and subcutaneous implants. Dr. Maureen Lindsay, Ardana's CEO, said "We are very encouraged by the data anddevelopment progress of this novel testosterone cream, which we see ascomplementary to StriantTMSR, our buccal testosterone tablet already on themarket for men with hypogonadism." The male hypogonadism market has experienced rapid growth over the last fiveyears, driven by novel gel formulations which now make up 76% of the market byvalue. The current US market size is estimated to be $473 million (IMS MAT Nov05).
