StemCells, Inc. Announces Completion of the First of Two Cohorts in its Dry Age-Related Macular Degeneration Trial NEWARK, Calif., Feb. 12, 2014 (GLOBE NEWSWIRE) -- StemCells, Inc. (Nasdaq:STEM) announced today that it has completed enrollment of the first of two planned patient cohorts in the Company's clinical trial of its proprietary HuCNS-SC^® product candidate (purified human neural stem cells) for dry age-related macular degeneration (AMD). This cohort consisted of eight subjects, four of whom each received 200,000 cells and four of whom each received1,000,000 cells. The last patient in this cohort wastransplanted by Dr. Ted Leng, M.D. Director of Ophthalmic Diagnostics at the Byers Eye Institute at Stanford. "Our immediate goal for the study in the next quarter is to complete enrollment of the second cohort. The eight patients in this stage of the trial will have better visual acuity than those in the first cohort," said Stephen Huhn, M.D., FACS, FAAP, Vice President, CNS Clinical Research at StemCells, Inc."We are expanding the trial from two sites at the beginning to ultimately a total of five sites, and with additional sites actively evaluating patients, the second cohort should be completed by mid-year. We also expect to announce interim follow-up data on the first cohort later this year. Following enrollment of the second cohort, we expect to initiate a controlled phase II efficacy proof-of-concept study by year end." About Age-Related Macular Degeneration Age-related macular degeneration refers to a loss of photoreceptors (rods and cones) from the macula, the central part of the retina.AMD is a degenerative retinal disease that typically strikes adults in their 50s or early 60s and gradually progresses to destroy central vision.According to the Foundation Fighting Blindness website, an estimated 10 million people in the U.S. either have AMD or are at substantial risk for receiving the diagnosis. Overall, about 85% of patients with AMD suffer from the dry form of the disease, and the advanced dry form of AMD is referred to as Geographic Atrophy. About the Trial The Phase I/II trial will evaluate the safety and preliminary efficacy of HuCNS-SC cells as a treatment for dry AMD.The investigation will be divided into two sequential cohorts. Subjects will be enrolled into each cohort based on best-corrected visual acuity (BCVA) visual acuity as determined by the Electronic Early Treatment Diabetic Retinopathy Study (E-ETDRS) acuity test. BCVA of less than or equal to 20/400 in the Study Eye will be enrolled in Cohort I. Subjects with BCVA of 20/320 to 20/100 in the Study Eye will be enrolled in Cohort II. Cohort I will consist of four subjects who will undergo transplant with 200,000 cells followed by four subjects who will undergo transplant with 1 million cells. Cohort II will consist of 8 subjects who will undergo transplant with 1 million cells. The HuCNS-SC cells will be administered by a single injection into the space behind the retina in the most affected eye.Patients' vision will be evaluated using both conventional and advanced state-of-the-art methods of ophthalmological assessment.Evaluations will be performed at predetermined intervals over a one-year period to assess safety and signs of visual benefit. Patients will then be followed for an additional four years in a separate observational study. The trial is currently enrolling patients at four centers: Retina Foundation of the Southwest, Dallas, TX; Byers Eye Institute at Stanford, Stanford Hospital and Clinics; Palo Alto, CA; New York Eye and Ear Infirmary, New York City, NY; and Retina Research Institute of Texas, Abilene, TX. Patients who are interested in participating in the study should contact the Retina Foundation of the Southwest at 214-363-3911, Byers Eye Institute at 650-498-4486, the New York Eye and Ear Infirmary at 212-979-4251, or the Retina Research Institute of Texas at 325-690-4414.

The Company's preclinical research has shown that HuCNS-SC cells can be directly transplanted in the central nervous system (CNS) with no sign of tumor formation or adverse effects.Because the transplanted HuCNS-SC cells have been shown to engraft and survive long-term, there is the possibility of a durable clinical effect following a single transplantation.StemCells believes that HuCNS-SC cells may have broad therapeutic application for many diseases and disorders of the CNS, and to date has demonstrated human safety data from completed and ongoing clinical studies. About StemCells, Inc. StemCells, Inc. is engaged in the research, development, and commercialization of cell-based therapeutics and tools for use in stem cell-based research and drug discovery. The Company's lead therapeutic product candidate, HuCNS-SC® cells (purified human neural stem cells), is currently in development as a potential treatment for a broad range of central nervous system disorders.In a PhaseI clinical trial in Pelizaeus-Merzbacher disease (PMD), a fatal myelination disorder in children, the Company has shown preliminary evidence of progressive and durable donor-derived myelination in all four patients transplanted with HuCNS-SC cells.The Company is conducting a Phase I/II clinical trial in chronic spinal cord injury in Switzerland, Canada and the United States, and has reported positive interim data for the first three patients.. In addition, the Company is pursuing preclinical studies in Alzheimer's disease, with support from the California Institute for Regenerative Medicine (CIRM).StemCells also markets stem cell research products, including media and reagents, under the SC Proven® brand.Further information about StemCells is available at http://www.stemcellsinc.com.
