Doernbecher researchers to study effectiveness of stem cell transplant in human brain

13.03.2006


First-of-its-kind clinical trial will explore safety, preliminary efficacy of injecting human stem cells directly into the brain to treat fatal pediatric neurodegenerative disorder



Researchers in Doernbecher Children’s Hospital at Oregon Health & Science University will begin a Phase I clinical trial using stem cells in infants and children with a rare neurodegenerative disorder that affects infants and children. The groundbreaking trial will test whether HuCNS-SC(TM), a proprietary human central nervous stem cell product developed by StemCells, Inc. is safe, and whether it can slow the progression of two forms of neuronal ceroid lipofuscinosis (NCL), a devastating disease that is always fatal. NCL is part of a group of disorders often referred to as Batten disease.

"NCL is a heartbreaking and devastating diagnosis for children and their families," said Robert D. Steiner, M.D., F.A.A.P., F.A.C.M.G., vice chairman of pediatric research, head of the Division of Metabolism and the study’s principal investigator at Doernbecher Children’s Hospital, OHSU. Steiner also is an associate professor of pediatrics, and molecular and medical genetics in the OHSU School of Medicine. "While the preclinical research in the laboratory and in animals is promising, it is important to note that this is a safety trial and, to our knowledge, purified neural stem cell transplantation has never been done before. It is our hope that stem cells will provide an important therapeutic advance for these children who have no other viable options."


NCL is caused by mutations or changes in the genes responsible for teaching the body how to make certain enzymes. Without these enzymes or proteins, material builds up inside brain neurons and other brain cells, causing a rapidly progressive decline in mental and motor function, blindness, seizures and early death. This study addresses two forms of NCL: infantile neuronal ceroid lipofuscinosis (INCL) and late-infantile neuronal ceroid lipofuscinosis (LINCL). Tragically, children with INCL typically die before age 5 and those with LINCL typically do not live past age 12.

"If delivering stem cells directly into the human brain is safe and effective, it will, in my opinion, be a major step forward in the efforts of scientists and clinicians around the country to find new treatments with the potential to help tens of thousands of patients with degenerative brain diseases," said co-investigator Nathan Selden, M.D., Ph.D., F.A.C.S., F.A.A.P. "I am proud that Doernbecher Children’s Hospital will be part of this effort." Selden is Campagna Associate Professor of Pediatric Neurological Surgery and head of the Division of Pediatric Neurological Surgery, Doernbecher and OHSU School of Medicine.

Up to six children from Oregon or around the country will undergo HuCNS-SC transplantation at Doernbecher. Previous studies of mice that are missing one of the enzymes that causes NCL have shown HuCNS-SC increases the amount of the missing enzyme, reduces the amount of abnormal material in the brain and prevents the death of some brain cells. No major side effects have been reported in animals.

StemCells, Inc. received clearance from the U.S. Food and Drug Administration to initiate a Phase 1 clinical trial of HuCNS-SC in October 2005. The company believes this will be the first trial using a purified composition of neural stem cells as a potential therapeutic agent in humans.

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
