VILLA GUARDIA, Italy, Oct. 10, 2013 (GLOBE NEWSWIRE) -- Gentium S.p.A. (Nasdaq:GENT) (the "Company") announced today that the European Medicines Agency's Committee for Orphan Medicinal Products ("COMP") has issued a positive opinion on the Company's application for orphan medicinal product status for Defibrotide for the prevention of Graft versus Host Disease ("GvHD"). The positive opinion of the COMP has now been forwarded to the EU commission for final approval and publication in the EU community register.

Orphan drug status is granted to products that can be used in the diagnosis, treatment or prevention of life-threatening diseases with an incidence of no more than 5 in 10.000 in the European Union. In order to receive Orphan status, there must also be either no satisfactory method of diagnosis, prevention or treatment of the authorized condition, or if such a method exists, the medicine must potentially be of a significant benefit to those affected by the condition. Orphan status confers 10 years of marketing exclusivity in all EU member countries following approval and in addition a range of other benefits during the development and regulatory review process including scientific assistance for study protocols, access to the centralized review process covering all member countries and a reduction or elimination of registration and marketing authorization fees.

Dr. Khalid Islam, Gentium's Chairman and Chief Executive Officer said, "Graft versus Host Disease is one of the most important and potentially fatal complications of hematopoietic stem cell transplantation ("HSCT") that afflicts up to 50% of all donor transplant patients. We are pleased to have received a positive opinion for this second indication from the COMP for orphan drug status in Europe. Based on its differentiated and novel mechanism of action when compared with currently used drugs and the encouraging clinical results obtained in prevention of GvHD (Corbacioglu et al., Lancet 2012) we believe that Defibrotide will address a significant unmet medical need for this potentially life-threatening disease. We look forward to planning and initiating additional studies to explore the full potential of Defibrotide in this indication."

About GvHD

Graft versus Host Disease (GvHD) is one of the most important and potentially fatal complication of hematopoietic stem cell transplantation (HCT). GvHD is seen most often in cases where the blood marrow donor is unrelated to the patient or when the donor is related to the patient but not a perfect match. It can occur in 30-50% of patients transplanted with either an HLA-matched sibling donor or matched unrelated donor.
