SAN DIEGO, Calif., April 16 /PRNewswire/ -- Ceregene, Inc., a biopharmaceutical company, today presented long term follow-up data from a Phase 1 clinical trial of CERE-120, a gene therapy product in development for the treatment of Parkinson’s disease, demonstrating a 36 percent (p<0.001) reduction in Parkinson’s symptoms at 12 months after administration, as measured by the Unified Parkinson’s Disease Rating Scale (UPDRS) motor “off” score (“motor off” meaning patients were off Parkinson’s medication at evaluation time). CERE-120 was also shown to be well tolerated in this study. The 12-month results were presented today by Philip Starr, M.D., Ph.D., associate professor of neurosurgery at the University of California, San Francisco at the American Association of Neurological Surgeons (AANS) annual meeting in Washington D.C. These data were also highlighted by the AANS in a specific CERE-120 press release issued by the Association.
