A Phase I clinical trial led by investigators from the University of California, San Francisco (UCSF) and sponsored by Stem Cells Inc., showed that neural stem cells successfully engrafted into the brains of patients and appear to have produced myelin.
The study, published in Wednesday's issue of Science Translational Medicine, also demonstrated that the neural stem cells were safe in the patients’ brains one year post transplant.
The results of the investigation, designed to test safety and preliminary efficacy, are encouraging, said principal investigator David H. Rowitch, MD, PhD, a professor of pediatrics and neurological surgery at UCSF, chief of neonatology at UCSF Benioff Children’s Hospital and a Howard Hughes Medical Institute Investigator.
“For the first time, we have evidence that transplanted neural stem cells are able to produce new myelin in patients with a severe myelination disease,” said Nalin Gupta, MD, PhD, associate professor of neurological surgery and pediatrics and chief of pediatric neurological surgery at UCSF Benioff Children's Hospital, and co-principal investigator of the PMD clinical trial.
“We also saw modest gains in neurological function, and while these can’t necessarily be attributed to the intervention because this was an uncontrolled trial with a small number of patients, the findings represent an important first step that strongly supports further testing of this approach as a means to treat the fundamental pathology in the brain of these patients.”
