ARDANA ANNOUNCES COMPLETION OF EUROPEAN MUTUAL RECOGNITION PROCESS FOR Striant™ TESTOSTERONE REPLACEMENT THERAPY IN MEN WITH PRIMARY OR SECONDARY HYPOGONADISM

- European Roll Out Anticipated From Second Quarter 2005 -

Edinburgh, UK; 27 October 2004 …….Ardana Bioscience, the emerging pharmaceutical company dedicated to improving reproductive health is pleased to announce that its partner, the US pharmaceutical company Columbia Laboratories, Inc., (NASDAQ: CBRX) has completed the European Mutual Recognition Process for Striant™, the first buccal (gum surface) tablet testosterone replacement therapy for men with primary or secondary hypogonadism.

Dr Maureen Lindsay, Ardana Chief Executive Officer said ‘This is a key milestone for Ardana and Columbia and we are delighted to receive a positive opinion from all major markets including Germany, France, Spain, Portugal, Italy and the Scandinavian countries. Ardana received UK marketing authorization and license for Striant™ in April this year and our specialist sales force have begun to market the product here. After conversion into national marketing authorisations across Europe, we anticipate product roll-out will begin in the second quarter of 2005.’

Striant™ is the first gum surface product for testosterone replacement therapy in men with primary or secondary hypogonadism (ie those suffering from a deficiency or absence of testosterone) and it provides patients and clinicians with a new, discreet treatment option.

Striant™ delivers testosterone through the gum and cheek surfaces that are in contact with the tablet and directly into the bloodstream, avoiding first pass liver metabolism. The tablet is applied to the gum twice daily (bd) at twelve hour intervals eg once in the morning and once in the evening. Once in place, it adheres, softens into a gel-like form and delivers consistent, controlled and sustained levels of mean serum total testosterone that approximate the physiological levels seen in healthy young men *1-3.

Male Hypogonadism (which is characterised by testosterone levels below the normal range) can be caused by conditions associated with the testes, pituitary gland or hypothalamus gland, or by a genetic disorder. Signs and symptoms of hypogonadism can include decreased libido (sexual desire), erectile dysfunction, fatigue, depression, reduced muscle mass and osteoporosis. Testosterone replacement therapy is designed to provide and maintain normal levels of testosterone.

Ardana acquired key European rights to Striant™ from Columbia Laboratories, Inc. in October 2002. Mipharm, S.p.A. will be responsible for commercialising Striant™ in Italy.
