Lyon, France - July 11, 2023 - 5:40 pm CEST - Theranexus, an innovative biopharmaceutical company specializing in the treatment of rare neurological diseases (the "Company"), today announces the launch of a global offering of approximately 4 million euros (the " Offering") through the issuance of new shares at a fixed price of 1.28 euros per share exclusively reserved (i) for specialized and strategic investors falling into the categories below, by way of an accelerated book-building, and (ii) for retail investors through the PrimaryBid platform.

The proceeds of the Global Offering, combined with the Company's existing funds, are intended to contribute to finance the pivotal Phase 3 trial of the Batten-1 drug candidate, designed to treat patients suffering from the rare neurological disease Batten disease. The funds would also be used to finance the other research and development activities of the Company, as well as its general corporate needs.

Theranexus, in partnership with the Beyond Batten Disease Foundation (BBDF), recently obtained approval from the Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for the design of the pivotal phase 3 study of its drug candidate Batten-1. The Company also reports encouraging preliminary results at 6 months from the phase 1/2 study, suggesting a beneficial effect of Batten-1 on neuronal death and stabilization of motor function in treated patients. Encouraged by these latest developments, the Company will launch the pivotal phase 3 of its clinical trial at the end of the second half of 2023. The costs of this phase 3, which should be completed by the end of 2026, are estimated at 5 million euros per year for the next 3 years.

Mathieu Charvériat, CEO of Theranexus, said "We will initiate phase 3 of Batten-1 at the end of 2023, using the funds generated by this operation, and building upon FDA and EMA positive opinions and encouraging preliminary clinical results. The design of the study will enable us to communicate a frequent and rich newsflow to our shareholders, until the product is registered in Europe and the United States. We would like to thank the investors involved in this transaction, and in particular the BBDF Foundation, which, in addition to its strong operational and strategic support for the scientific and clinical development of Batten-1 since 2019, is now committed to supporting us by acquiring a stake in the Company."

On June 30, 2023, Theranexus had available cash of €4.7 million, reflecting a controlled cash consumption over the second quarter, which included in particular the repayment of the annual loan repayment schedule under the State Guaranteed Loan (PGE) for €0.4 million.

About Batten-1

Batten-1 is a new proprietary and exclusive pharmaceutical speciality whose active ingredient is miglustat. The mechanism of action of this active ingredient blocks the accumulation of glycosphingolipids and neuroinflammation, thereby significantly reducing neuronal death, the cause of progressive loss of function in patients. For patients over 17 years of age in the Phase 1/2 study, the product is administered in solid form. In the Phase 3 study, it will be administered in a liquid form, more suited to a paediatric population.

Study design Phase 1/2: This is an open-label study involving 6 patients over 17 years of age with Batten CLN3 disease, treated with miglustat up to 600 mg/day for 2 years. The primary endpoint was safety and tolerability, assessed by adverse event reporting, bioassays and ECG, as well as miglustat pharmacokinetics. Secondary endpoints included efficacy parameters: the Unified Batten Disease Rating Scale, visual acuity, measurement of brain volumes by magnetic resonance imaging and measurement of retinal neuronal layer thickness by optical coherence tomography. Batten-1 dose escalation to a maximum of 600 mg/d was well tolerated, with no serious adverse events or discontinuations. The most frequently reported adverse events were gastrointestinal, reversible and mostly mild to moderate in intensity, demonstrating the good safety profile of Batten-1 in this population. Batten-1 will continue to be evaluated in these patients for a total of 24 months. Further information is available at

About Batten disease

Juvenile Batten disease or Spielmeyer-Vogt disease, also known as CLN3 disease, is a rare, fatal genetic disorder of the nervous system for which there is no cure. It belongs to the group of neuronal ceroid-lipofuscinoses (NLC). Over 400 mutations in 13 genes have been associated with NLC variants, which differ essentially in the age of onset of symptoms. The first symptom of the juvenile form, progressive vision loss, appears between the ages of 4 and 6. This is followed by cognitive and behavioral problems and motor difficulties. Convulsions appear within 2 to 4 years of onset. Gradually, patients decline both physically and mentally. Eventually, they become wheelchair-bound or even bedridden, before dying prematurely.

The disease is always fatal - usually in late adolescence or early adulthood. In the USA and Europe, Batten disease is the most prevalent NLC, affecting around 2,000 patients[3] . From a pathophysiological point of view, interactions between neurons and glial cells play a key role in the onset and progression of all NLCs.

About the Beyond Batten Disease Foundation (BBDF)

The Beyond Batten Disease Foundation (BBDF) is the world's largest non-profit organization dedicated to funding research to treat and cure juvenile Batten disease (CLN3). Since its creation in 2008, over $35 million has been invested in research through donations, co-funding and strategic partnerships. BBDF spearheads a unique and coherent strategy, integrating independent scientific resources and collaboration with related organizations to conduct research into juvenile Batten disease. BBDF-sponsored research initially uncovered the mechanisms of the disease[4] . Today, a treatment is in sight. BBDF-funded research has led to the discovery of a drug, Batten-1, which slows disease progression in models of Batten disease. For more information, visit
