New Advance to the Theranexus and BBDF Batten-1 Program for Juvenile Batten Disease (CLN3)

Beyond Batten Disease Foundation is excited to share the latest accomplishment on our journey to find a treatment for juvenile Batten disease. Six young adults over 17 years old have been successfully treated with miglustat over the past year. The results show that the drug is safe to use at the maximum dose. These results, in conjunction with a recent meeting with the FDA, allow us to proceed to the Phase III efficacy trial in 2023. Your support has been critical in the development of this program. We are one step closer to having the first ever treatment for CLN3 disease. Thank you for making this possible.

CONGRATULATIONS to the 2022 BDSRA Australia Research Grant Winners!

Thank you NCL Congress for allowing BBDF to be a sponsor this year as they gathered families, scientists, and industry experts to discuss gaps, lessons learned, and emerging therapeutic approaches in NCL preclinical and clinical research.

Theranexus and BBDF Finalize Recruitment For Phase I/II Trial to Evaluate Batten-1 in Batten Disease

Lyon, France – Austin, Texas, United States – 6 September 2022 – 6 pm CEST – Theranexus, a biopharmaceutical company innovating in the treatment of neurological diseases and pioneer in the development of drug candidates modulating the interaction between neurons and glial cells, and the Beyond Batten Disease Foundation (BBDF), have today announced finalization of recruitment of the last patient for the Phase I/II clinical trial to evaluate the tolerability, pharmacokinetics of the Batten-1 drug candidate in juvenile (CLN3) Batten disease.

A total of six patients with juvenile Batten disease aged 17 and over are enrolled in the Phase I/II clinical trial. The Batten-1 drug candidate containing the active ingredient miglustat is administered in escalating doses. The initial tolerability and pharmacokinetic data for miglustat obtained after the first 9 weeks of treatment in this population will serve to initiate Phase III, and Phase I/II patients are being treated and evaluated over a 24-month period.

Franck Mouthon, Chairman of Theranexus, said: “Finalization of recruitment for our Phase I/II trial is an important milestone in the development of Batten-1, a drug candidate that aims to significantly slow progression of juvenile Batten disease for which there is currently no available treatment. Our goal for the next stages in the development process is to launch an international pivotal Phase II/III trial in 2023.”

Craig Benson, Chair of the Beyond Batten Disease Foundation, added: “As parents and representatives of patients with juvenile Batten disease and their families, we are delighted with the enrollment of the last patient in the Phase I/II trial. This new Batten-1 treatment offers tremendous hope for our children affected by the disease.”

The Phase I/II trial is being conducted by referral centers for Batten disease in the United States, with Dr. Gary Clark, Chief of Child Neurology at Texas Children’s Hospital in Houston, as principal investigator.

About Batten-1
Batten-1 is a novel and exclusive proprietary drug containing the active ingredient miglustat. The mechanism of action of this substance blocks the accumulation of glycosphingolipids and neuroinflammation to prevent brain cell death. In the Phase I/II trial, Batten-1 is administered to patients over 17 years of age in solid form, and in Phase III it will be administered in a liquid form better suited to children.

About Batten disease
Juvenile Batten disease, also known as Spielmeyer-Vogt or CLN3 disease, is a rare, fatal, inherited disorder of the nervous system for which there is no treatment or cure. Juvenile Batten disease belongs to a group of disorders referred to as neuronal ceroid lipofuscinoses (NCLs). Over 400 different errors in 13 genes have been attributed to various forms of NCL, which differ from one another primarily by when symptoms first appear. The first symptom in the juvenile form, progressive vision loss, appears between the ages of 4 and 6 which is followed by personality changes, behavioral problems, and slowed learning. Seizures commonly appear within 2-4 years of the onset of disease. Over time, patients continue to decline mentally and physically. Eventually, those affected become wheelchair-bound, are bedridden, and die prematurely. Psychiatric symptoms or psychosis can appear at any time.

Juvenile Batten disease is always fatal; usually by the late teens to early 20s. In the United States and Europe, the juvenile form is the most common of the NCLs, which together, affect nearly 3,000 patients. In pathophysiological terms, interactions between neurons and glial cells play key roles in the emergence and progression of all the NCLs.
About Beyond Batten Disease Foundation

Beyond Batten Disease Foundation (BBDF) is the world’s largest nonprofit organization dedicated to funding research for a treatment and cure for juvenile (CLN3) Batten disease. Since its inception in 2008, over $35 million has been invested in research by leveraging donations, co-funding and strategic partnerships. BBDF is spearheading a unique, cohesive strategy, incorporating independent scientific resources and collaboration with related organizations to drive research in juvenile Batten Disease . Today there is a treatment in sight. BBDF funded research has discovered a drug – Batten-1 – that slows the progression of the disease in Batten models.

BBDF 101 Update

BBDF 101 Update

Theranexus announced yesterday that it is now, more than ever, committed to support patients with rare neurological disorders by focusing all its research efforts on these diseases, starting with CLN3. In this context, the project with Beyond Batten Disease Foundation (BBDF) becomes their flagship project and they have decided to dedicate all resources and efforts to make this project a success to benefit of the CLN3 disease community. Following the initiation of the ongoing Phase l/ll clinical study involving 6 young adult patients, Theranexus and BBDF are in the process of finalizing discussions with the FDA to initiate Phase III.
