BBDF Supporting the National Institutes of Health CLN3 Natural History Study
BBDF is proud to support the CLN3 Natural History Study at the National Institutes of Health (NIH). A summary of publications arising from this study can be found here.
National Institutes of Health Seek Individuals to Participate in a Research Study
Researchers at the National Institutes of Health (NIH), in Bethesda, Maryland, seek individuals with CLN3 (Juvenile Neuronal Ceroid Lipofuscinosis, Batten disease) and their family members to participate in a research study. CLN3 is a neurodegenerative disease, with typical onset seen in children. Individuals with CLN3 may have symptoms such as visual impairment/blindness, seizures, personality and behavioral changes, dementia and loss of motor skills. The main purpose of this research study is to identify markers of disease to better detect, monitor, and understand CLN3.
As part of the ongoing CLN3 natural history study, participants will be recruited to the DBS study with the aim of identifying biomarkers that can aid in CLN3 screening and diagnosis at birth. The researchers believe that an early diagnosis of CLN3, prior to the onset of symptoms, will facilitate early intervention and treatment when available.
The study is noninvasive and is considered minimal risk, eliminating the need for an in-person visit to the NIH. Participants will be consented online or in person to obtain permission to request the newborn spot card collected at birth from the state. Recruitment is set to begin in the highlighted states of California, Maryland, and New York.
Efforts are underway to secure approvals from other states, allowing for the expansion of recruitment to additional regions. The researchers welcome assistance in sharing information about this new study with families and other CLN3 community organizations and contacts.

Highly Promising 12-month results in the Phase I/II trial of Batten-1
Lyon, France – Austin, Texas, United States – 29 September 2023 – 7.30am – CET – Theranexus, a biopharmaceutical company innovating in the treatment of rare neurological diseases, and the Beyond Batten Disease Foundation (BBDF), present very encouraging interim results for efficacy and safety after 12 months of treatment in their Phase I/II trial for Batten disease (CLN3) at NCL2023, the International Congress on Neuronal Ceroid Lipofuscinoses held in Hamburg (Germany) from 26 to 30 September 2023.
For Professor Gary Clark, the trial’s principal investigator and Chief of Child Neurology at Texas Children’s Hospital in Houston, “The Phase I/II results for Batten-1 are highly promising, as we have observed a reduction in neurofilaments and glycosphingolipids and no notable progression of motor symptoms after 12 months of treatment in our 6 patients aged 17 years and over. This is unprecedented in the indication, and Batten-1 is thus a source of great hope for children affected by the disease and for their families”. Professor Clark will be presenting the 12-month interim efficacy and safety results at the “Translational Research Clinical” session on Friday 29 September at 12.25pm (CEST).
The 12-month treatment results further support the 6-month results announced in mid-June 2023. The new results, achieved after 12 months of treatment, show an average 32% decline in neurofilament light chain (NfL) levels in patient serum (as a reminder, 17% after 6 months’ treatment). Neurofilaments are a recognized biomarker of neurodegeneration. A 64% reduction in this biomarker is also observed in the cerebrospinal fluid (CSF). After twelve months of treatment, in line with preclinical data the results also confirmed a reduction in the glycosphingolipids involved in the disease (Gb3 reduction of 45%) which, when they accumulate, are toxic to neurons. Clinically, there was notably less worsening of motor symptoms evaluated by the modified UBDRS physical assessment subscale after 12 months than what is expected in this naturally progressive disease.
For Theranexus’ CEO, Mathieu Charvériat: “We are delighted with these 12-month results which confirm and complement our initial 6-month results. The decrease of biomarker levels confirms the effect of Batten-1 on neuronal death, and the clinical course did not worsen. These consistent results represent a significant endorsement of the mechanism of action and demonstrate the strong therapeutic potential of Batten-1 in Batten disease (CLN3)”.
As a reminder, the Phase I/II trial conducted by Theranexus and BBDF to evaluate their drug candidate, Batten-1, includes six patients with Batten disease (CLN3) aged 17 years and over. The patients are being treated over a 24-month period.
The presentation of the 12-month efficacy and safety results will be available online on 29 September after market closing.

Rare Sibling Stories Looking for Stories!
Rare Sibling Stories is looking for siblings to highlight on their platforms! They would love to feature siblings of individuals with Batten disease. Siblings (any age) just need to fill out a short survey with this link: https://forms.gle/SbogDffzfphoAFjj7
They created Rare Sibling Stories to provide a space for siblings of individuals with rare diseases to share their stories and connect with others like themselves. Rare Sibling Stories is gathering information from siblings to highlight on the Rare Sibling Stories website and social media!
NORD’s Batten Disease Patient Assistance Program
Having a rare disease is difficult. Adding in the complex care required to treat or manage that disease and figuring out how to pay for it makes a rare diagnosis even harder. NORD’s Batten Disease Patient Assistance Program offers eligible individuals diagnosed with Batten Disease financial support to pay for out-of-pocket healthcare costs that are directly related to the care and treatment of Batten. These Patient Assistance Programs for individuals diagnosed with Batten disease have been expanded. Eligible individuals may now apply for financial support with health insurance premiums and copay expenses as well as Emergency Relief (critical, non-medical needs). Eva’s Butterfly Wishes for rare children may also be available. Learn more below.
