About this study
Official title: Direct CNS Administration of a Replication Deficient Adeno-associated Virus Gene Transfer Vector Serotype rh.10 Expressing the Human CLN2 cDNA to Children With Late Infantile Neuronal Ceroid Lipofuscinosis (LINCL)
This is a proposed follow up study on the investigators previous gene transfer human clinical trial entitled "Administration of a Replication Deficient Adeno-associated Virus Gene Transfer Vector Expressing the Human CLN2 cDNA to the Brain of Children with Late Infantile Neuronal Ceroid Lipofuscinosis" (Weill Cornell IRB# 0401007010). As in the previous study, the investigators propose to administer a biologic by direct gene transfer into the brain and assess its safety on children with a fatal genetic disease of the central nervous system (CNS). The disease is Late Infantile Neuronal Ceroid Lipofuscinosis (LINCL, a form of Batten disease). This will be accomplished by using delivery of a gene (method called gene transfer) to administer to the brain an experimental drug called AAVRh.10CUhCLN2, a gene transfer vector.
Read the detailed description
The investigators propose to assess a new drug to treat children with a form of Batten Disease called Late Infantile Neuronal Ceroid Lipofuscinosis (LINCL). These children are born with genetic changes called mutations in their CLN2 gene that result in the inability of the brain to properly recycle proteins. The recycling failure leads to death of the nerve cells in the brain and progressive loss of brain function. Children with Batten disease are normal at birth but by age 2 to 4 have motor and vision problems which progress rapidly to death at age approximately 10 years old. There are no therapies available to treat the disease.
The experimental gene transfer procedure treatment the investigators propose consists of augmenting the abnormal gene by a good copy. A virus is used to deliver the good gene to the nerve cells. Since the disease is due to an abnormal CLN2 gene, the aim of this study is to add a normal copy of the CLN2 gene to the brain of affected children to try to reverse death of cells in the brain. Previously the investigators have used a virus called adeno-associated virus 2 (AAV2) as the gene delivery system. That study showed that viral delivery of the gene was safe. We now propose to use a slightly different virus called AAVrh.10 as a gene delivery system and use 2 different doses of the virus. Children with Batten disease will get the drug injected into the brain and will receive extensive neurological assessment at intervals to determine if the transfer slows the rate of progress of the disease.
The primary aims of the study are: (1) to assess the hypothesis that direct administration of AAVrh.10CUhCLN2 to the brain of children with LINCL can be achieved safely and with minimal toxicity; and (2) to evaluate the hypothesis that direct administration of AAVrh.10CUhCLN2 to the brain of children with LINCL will slow down or halt progression of the disease as assessed by neurological rating scales and quantitative MRI (primary variables).
The investigators have recently completed a study in which the normal copy of the gene was surgically delivered to 12 locations in the brain in 10 children with LINCL. The children were assessed by a number of neurological and imaging parameters prior to and after gene transfer. The data demonstrated that the gene transfer was well tolerated and had a small impact on the progression of the disease and suggested that higher doses and a better delivery system may provide greater benefit. The previous study used the viral gene transfer vector adeno-associated virus type 2 (AAV2) at a dose of 2,000,000,000,000 molecules of the drug (2 x 10^12 particle units). The investigators now propose a very similar study with delivery of the identical payload with a slightly different viral gene delivery system based on the virus AAVrh.10.

AAVrh.10CUhCLN2 vector 9.0x10^11 genome copiesBiological
The experimental drug for this second generation study has a genome identical to that used in our previous study and delivers the same gene, but instead of an AAV2 capsid (protein shell of the virus), the new vector has the capsid of AAVrh.10, a clade E AAV derived from rhesus macaque (a species of Old World monkeys). The first dose that was given to the first 6 subjects is 9.0x10^11(900,000,000,000 molecules of the drug) genome copies/subject. In regards to drug administrations, we propose to perform 2 series of 6 simultaneous administrations of vector for 75 min each. Each subject will receive the assigned dose of AAVrh.10CUhCLN2, divided among 12 locations delivered through 6 burr holes (2 locations at 2 depths through each hole), 3 burr holes per hemisphere.

- We chose an initial dose two fold lower of 9.0x10\^11 genome copies/subject (Group A). Initially, the study plan was to proceed to Group B, which would receive a higher dose of 1.8x10\^12 genome copies if the initial dose was well tolerated. However, after assessing the MRI images of the first 6 children who received the dose of 9.0x10\^11 gc, we discovered that 4 of the 6 subjects at 6 months and 1 of the 6 subjects at 12 months exhibited varying degrees of T2 hyperintensities related to diffusion restriction at the sites of vector deposition. Although there are no clinical correlates to these MRI findings, we have decided to lower the dose by ½ log to 2.85x10\^11 gc for the remaining subjects to be enrolled in protocol #0810010013. The volume of the drug solution will be the same as in Group A, but the concentration of the vector will be ½ log less.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This is a proposed follow up study on the investigators previous gene transfer human clinical trial entitled "Administration of a Replication Deficient Adeno-associated Virus Gene Transfer Vector Expressing the Human CLN2 cDNA to the Brain of Children with Late Infantile Neuronal Ceroid Lipofuscinosis" (Weill Cornell IRB# 0401007010).

The disease is Late Infantile Neuronal Ceroid Lipofuscinosis (LINCL, a form of Batten disease).

What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Weill-Cornell LINCL scale from Baseline to 18 months (time frame: 18 Months). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01161576, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
