uniQure B.V., a leader in the field of human gene therapy, today announced the start of its Phase I clinical trial in acute intermittent porphyria (AIP) with the treatment of the firstpatient. The study is conducted under the aegis of the AIPGENE consortium, a pan-European collaboration funded in part by the European Commission’s Seventh Framework Program with the aim to develop a gene therapy for the treatment of AIP, a rare and devastating disease caused by mutations in the porphobilinogen deaminase gene(PBGD). AIP can be life-threatening and the long-term effects include irreversible nerve damage, liver cancer and kidney failure. uniQure was granted orphan drug designation for the treatment of AIP in 2009 from the European Medicines Agency.
