Treatment
In June 1987, a Phase I clinical trial was launched at Weill Medical College of Cornell University to study a gene therapy method for treatment of the signs and symptoms of late infantile neuronal ceroid lipofuscinosis (LINCL). The experimental drug works by delivering a gene transfer vector called AAV2CUhCLN2 to the brain. In 2011, it was reported that the procedure, which involved injecting a harmless gene-bearing virus into the brain, is safe; and that, on average, it significantly slowed the disease's progression during the 18-month follow-up period.
In November 2006, after receiving FDA clearance, neurosurgeon Dr. Nathan Selden, pediatrician Dr. Fredirich Steiner, and colleagues at Doernbecher Children's Hospital at Oregon Health & Science University began a clinical study in which purified neural stem cells were injected into the brain of a six-year-old child with Batten disease, who had lost the ability to walk and talk. This patient was the first of six to receive the injection of a stem cell product from StemCells Inc., a Palo Alto biotech company. These are believed to be the first-ever transplants of fetal stem cells into the human brain. By early December, the child had recovered well enough to return home, and it was reported that there were some signs of speech returning. The main goal of Phase I clinical trials, however, was to investigate the safety of transplantation. Overall, the Phase I data demonstrated that high doses of human neural stem cells, delivered by a direct transplantation procedure into multiple sites within the brain, followed by twelve months of immunosuppression, were well tolerated by all six patients enrolled in the trial. The patients’ medical, neurological and neuropsychological conditions, following transplantation, appeared consistent with the normal course of the disease.

Famous quotes containing the word treatment:
“A regular council was held with the Indians, who had come in on their ponies, and speeches were made on both sides through an interpreter, quite in the described mode,the Indians, as usual, having the advantage in point of truth and earnestness, and therefore of eloquence. The most prominent chief was named Little Crow. They were quite dissatisfied with the white mans treatment of them, and probably have reason to be so.”
—Henry David Thoreau (18171862)
“Ambivalence reaches the level of schizophrenia in our treatment of violence among the young. Parents do not encourage violence, but neither do they take up arms against the industries which encourage it. Parents hide their eyes from the books and comics, slasher films, videos and lyrics which form the texture of an adolescent culture. While all successful societies have inhibited instinct, ours encourages it. Or at least we profess ourselves powerless to interfere with it.”
—C. John Sommerville (20th century)
“[17th-century] Puritans were the first modern parents. Like many of us, they looked on their treatment of children as a test of their own self-control. Their goal was not to simply to ensure the childs duty to the family, but to help him or her make personal, individual commitments. They were the first authors to state that children must obey God rather than parents, in case of a clear conflict.”
—C. John Sommerville (20th century)
