Ardana PLC21 November 2007 ARDANA ANNOUNCES POSITIVE RESULTS OF A SUPPLEMENTARY STUDY CONFIRMING THE HIGH DERMAL TOLERABILITY OF TESTOSTERONE CREAM Edinburgh, UK, 21 November 2007: Ardana plc (LSE:ARA) today announces that in arecently completed supplementary clinical trial, treatment with TestosteroneCream for the transdermal delivery of testosterone, has shown that it does notact as an irritant on skin. Testosterone Cream is in late-stage development formale hypogonadism. The study evaluated the dermal tolerability of Testosterone Cream on intact skinin subjects with healthy skin. Topical application of Testosterone Cream, aswell as negative and positive controls, was undertaken once daily during a21-day treatment period for an approximate duration of 23 hours per day. 40male volunteers were included in the study and all subjects received alltreatments i.e. Testosterone Cream, active-ingredient-free vehicle toTestosterone Cream (placebo), 0.9% sodium chloride in water (negative control)and 0.1% sodium dodecyl sulphate in water (positive control). Dermal reactionswere clinically assessed on study days 2-22 using an erythema score (range 0 to4 with 0 being no reaction and 4 being severe erythema reaction with infiltrateand/or dermal defect e.g. blisters/blebs/erosion). No statistically significant differences were found between Testosterone Cream,the placebo and the negative control whereas clear and significant irritationwas seen for the positive control with severe reactions observed in all subjectsby the end of the study. Several formulations for the delivery of testosterone to hypogonadal men aremarketed globally. Transdermal formulations are increasingly popular as theyavoid the inevitable "roller-coaster" effect experienced with earlierformulations such as injectables and implants. However, a significantdisadvantage of the currently available transdermal formulations is the skinreactions observed at the application site e.g. erythema, acne and dry skin atan incidence of up to 10%. Dr Huw Jones, Ardana's CEO said: "Testosterone Cream represents a very importantnear term opportunity for Ardana. The data from this study add low irritatantpotential to the other user-friendly properties of our formulation." Ardana has previously reported data from a Phase II dose-finding clinical trialshowing clear evidence of the efficacy and tolerability of Testosterone Cream.These data facilitated a Phase III pivotal registration study in men withconfirmed hypogonadism (testosterone deficiency), a study that is ongoing in theUSA.
