Neuronal ceroid lipofuscinosis

This early-stage trial tests a one-time gene therapy called CLN-301 in 7 children aged 3 to 10 with CLN3 Batten disease, a rare genetic disorder that causes progressive loss of vision, movement, and thinking skills. The therapy delivers a working copy of the CLN3 gene directly in…

This study tests whether injecting a replacement enzyme directly into the eye can slow or stop vision loss in children with CLN2 Batten disease, a rare genetic disorder that causes blindness and brain damage. Five children aged 2 to 6 who already receive brain infusions of the en…

This early-stage study tests a one-time gene therapy injection into the spinal fluid of children aged 1-18 with CLN7 Batten disease, a rare and fatal genetic brain disorder. The main goal is to check safety, but researchers will also measure changes in movement, thinking, and vis…

This study follows 10 people with CLN6 Batten disease who received a single dose of gene therapy (AT-GTX-501) in an earlier trial. Researchers are checking long-term safety and how the disease progresses over time. No new treatment is given in this follow-up.

ScreenPlus is a large pilot program that offers families the option to have their newborn screened for a panel of rare genetic disorders, in addition to standard newborn screening. The study aims to screen 100,000 infants born at eight hospitals in New York. Researchers will eval…

This study follows 35 children with CLN2 disease (a rare, severe brain disorder) who are taking cerliponase alfa (Brineura). Researchers will monitor for side effects and serious reactions over time. The goal is to better understand the long-term safety of this enzyme replacement…

This study follows 5 people with a rare, late-onset form of TPP1 deficiency (a brain disease) to track how their symptoms change over time. Researchers will use tests like brain scans, eye exams, and movement assessments to better understand the condition. The goal is to gather i…

This study looks at how children with CLN2 Batten disease develop over time, including their thinking, language, and motor skills. Researchers will compare children who receive treatment (cerliponase alfa) with those who do not. The goal is to find better ways to measure the dise…
