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 LINCL With Uncommon Genotypes and/or Moderate to Severe Impairment

The investigators propose to assess the safety and efficacy of a new administration method to deliver a biologic to children with a form of Batten disease using an experimental gene transfer procedure. This gene transfer procedure consists of delivering a good copy of the mutated gene to the nerve cells via a virus. These children are born with genetic changes called mutations 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 investigators previous clinical trial 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 and showed small, but significant benefits to the recipient. The investigators currently have an IRB approved protocol which uses a slightly different virus called AAVrh.10 as the gene delivery system. This 3rd protocol proposes to use the same virus AAVrh.10 as the gene delivery system and has expanded the eligibility criteria.

Read the detailed description

This study is designed to run parallel to our currently IRB approved protocol #0810010013 entitled "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," which will assess the safety and efficacy of the virus AAVrh.10 to deliver the CLN2 gene to children in the early stages of the disease. This current study proposes to assess the safety and efficacy of the administration of the same biologic to children who do not fit the criteria for IRB protocol #0810010013.

The differences between protocol #0810010013 and the proposed "parallel" protocol is that inclusion criteria have been modified to include children with any genotype (not only the 5 most common genotypes as in the currently approved protocol) and/or those who score below a 6 but at least a 1 on the Weill Cornell LINCL scale. The reason for expanding the eligibility criteria is to obtain a range of safety data for all children with LINCL, not only those with limited genotype and/or severity. Only 8 subjects will be administered the gene transfer vector in this "parallel" protocol. Subjects will be accrued through IRB approved protocol #0901010186 entitled, "Genotype-Phenotype Correlations of Late Infantile Neuronal Ceroid Lipofuscinosis (2)." Those who do not fit all criteria for the already approved gene transfer protocol (#0810010013) may have the opportunity to be enrolled in this proposed "parallel protocol" (Figure 1). The subjects in the new protocol will be compared to the 16 treated and 16 untreated children enrolled in IRB protocol #0810010013 and #0901010186, respectively.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in CNS function, as measured by the Weill Cornell LINCL Scale

    The Weill Cornell LINCL scale, a 12 point scale which combines assessment of feeding, gait, motor and language to give an overall assessment of various CNS functions (Appendix II for the paper describing the scale and Appendix VI for the scale)27. The lowest possible score is 0 (less progressed in disease) and the highest possible score is 12 (more progressed in disease). This rating scale evaluation will be performed by 2 independent pediatricians, on the basis of a videotaped evaluation. If the 2 independent scores differ by 1 or less they will be averaged and if they differ by greater than 1 point, a consensus will be obtained by a 3rd pediatrician. This outcome measure will look at changes over time.

    Measured: Screening, Pre-transfer, Months 1, 6, 12 and 18

  2. Safety, as measured by MRI

    3 imaging parameters (% gray matter volume, % ventricular volume and cortical apparent diffusion coefficient) correlate with age and the Weill Cornell LINCL scale. These 3 imaging parameters will be used to assess disease progression (control protocol) and safety of the gene transfer vector (vector protocol) over time. In addition to these imaging parameters we will also perform magnetic resonance spectroscopy (MRS) but the data obtained from this will be for information only for method development. This outcome measure will look at changes over time.

    Measured: Screening, Pre-transfer, Months 6, 12 and 18

Secondary outcomes (2)
  1. Change in Quality of Life, as measured by the Child Health Questionnaire (CHQ) or Infant Toddler Quality of Life (ITQoL) (depending on age)

    The CHQ or ITQoL, a quality of life questionnaire which will be completed by at least one parent/legal guardian at the time of the LINCL patients' visits to Weill Cornell. The survey will be administered independently to each parent to minimize observer bias if both parents are present. This outcome measure looks at a change over time.The lowest possible score is 0 (corresponds to lower health-related quality of life) and the highest possible score is 100 (corresponds to better health-related quality of life).

    Measured: Screening, Pre-transfer (optional) and Month 18

  2. Change in psychological development, as measured by the Mullen Scale

    The Mullen scale, a pediatric developmental psychological rating scale, will be administered by a developmental psychologist, and be videotaped. This outcome measure will look at changes over time. The lowest possible score is 0 (corresponds to less psychological development) and the highest possible score is 197 (corresponds to better psychological development).

    Measured: Screening, Pre-transfer (optional) and Month 18

What is this clinical trial studying?

A Phase 1/2 study testing AAVrh.10CUCLN2 in people with Late Infantile Neuronal Ceroid Lipofuscinosis and Batten Disease, run by Weill Medical College of Cornell University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 31 Aug 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 CNS function, as measured by the Weill Cornell LINCL Scale (time frame: Screening, Pre-transfer, Months 1, 6, 12 and 18). The study lists 2 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 NCT01414985, 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Aug 2020.
