ROTTAPHARM AND XYTIS PARMACEUTICALS LTD. ENTER INTO GLOBAL LICENSING AGREEMENT FOR XY 2401

Milan and London, Tuesday, 11 January 2005 - Rottapharm S.p.A. and Xytis Pharmaceuticals Ltd. announced they have signed an agreement regarding the development and commercialisation of Rottapharm's CR2249, a potential new psychotropic medication for the treatment of a variety of disorders.

Xytis has acquired an exclusive license to develop and market the compound in the United States, Canada, Japan, Australia and New Zealand, while Rottapharm retains rights in the rest of the world. The companies have not disclosed further terms of the agreement.

Professor Luigi Rovati, MD, President of Rottapharm S.p.A., commented: “XY 2401’s unique pharmacological properties may provide the basis for establishing a novel treatment paradigm in schizophrenia and potentially other CNS disorders. We are delighted to have entered into that partnership with Xytis, with the objective to progress the development of XY 2401 globally”

Dr. Werner Tschollar, founder of Xytis Pharmaceuticals Ltd., said: “XY 2401 is the first compound in-licensed by our company and a very exciting one in terms of mechanism of action, existing pre-clinical data and the possibility to address unmet medical needs in schizophrenia in particular, a major burden to society. Xytis will continue to develop its pipeline with a few additional in-licensing transactions of this type geared towards compounds that present the same level of innovation and address critical needs in the field of CNS.”

About XY 2401
XY 2401 is a positive allosteric glycine-site specific modulator of the glutamate NMDA receptor complex. As demonstrated in numerous peer-reviewed publications, endogenous dysfunction or dysregulation of neurotransmission mediated at the NMDA glutamate receptor complex may contribute significantly to the underlying pathophysiology of schizophrenia, in particular to the negative symptomatology and cognitive impairment of the disease. XY 2401 will start Phase I clinical studies in early 2005.
