Thiamine metabolism is impaired in Huntington Disease (HD). Our in-vivo studies showed that treatment with thiamine and biotin rescues HD symptoms. We are currently evaluating safety and tolerability of thiamine – biotin treatment for HD in a multicentric clinical trial.

Unmet need

• Progressive, and fatal neurodegenerative disorder caused by a genetic mutation leading to toxic function of Huntingtin protein.
• With a prevalence of 1 in 10,000 individuals is one of the most common rare diseases. There is no available cure. Current marketed solutions are just symptomatic and are associated with numerous side effects. There is no EMA approved therapy available.
• Global HD treatment market size was estimated at USD 500 million in 2024 and is projected to reach USD 1,871.2 million by 2030 (23.8% CAGR).

Innovative Solution

• Studies using mouse models and samples from patients showed impaired thiamine metabolism in HD, due to decreased expression of brain specific thiamine transporter ThTr2 (SLC19A3).
• High doses of thiamine and biotin attenuate HD pathology by:
  • Restoring brain bioenergetics (TPP levels) and increasing SLC19A3 transporter expression.
  • Preventing striatal atrophy, attenuating neuropathology, and improving motor coordination.
• Pre-clinical data eligible for Orphan Drug Designation (ODD).
• On going phase I/II multicentric clinical trial to evaluate safety and tolerability of thiamine and biotin treatment for HD (NCT04478734).

Technology Highlights

TAF1 isoform, where C-terminal end is loss, dysregulates expression of genes implicated in Multiple Sclerosis (MS) neuropathology. The detection of this isoform in blood and/or cerebrospinal fluid may be used as a biomarker for diagnosis and prognosis of MS. The novel mouse line expressing this isoform can be used to validate new MS therapies.

Unmet need

• Multiple sclerosis is a chronic autoimmune disease of unknown etiology characterized by neuroinflammation, demyelination and axonal damage, affecting 2.9 million people worldwide.
• 40% of patients are diagnosed >5 years from first MS symptoms.
• Although modifying disease treatments are available in the first stages, there is no cure.
• Main challenges for efficient diagnosis and treatment are related to a lack of:
  • understanding of the complex molecular basis of the disease
  • early diagnosis and prognosis of MS progression biomarkers
  • pre-clinical models for new therapies R&D

Innovative Solution

Our preclinical studies identify a TAF-1 isoform missing the C-terminal end (TAF1ex38) as a candidate biomarker for diagnosis and prognosis of multiple sclerosis (MS).

• Normal-appearing grey and white matter (NAG+WM) from MS patients showed reduced presence of TAF1ex38
• Reduced levels of TAF1ex38 can be explained by increased cathepsin B activity outside the lysosomes in brain tissue from MS patients
• Decreased TAF1ex38 levels were related to MS progression
• First mouse model of progressive MS, where deletion of TAF1ex38 mimics MS pathophysiology.
• The C-terminal end of TAF1 interplays with multiple transcriptional regulators involved in RNAPII transcriptional initiation and pause release, and its absence leads to downregulation of oligodendroglia genes, and upregulation of inflammatory genes.

Technology Highlights

1. Novel biomarker for diagnosis and prognosis
2. Minimally invasive method through blood or CFS extraction
3. Known molecular mechanism of action
4. Novel pre-clinical model for MS

Novel mutant variants of the fusion protein Etanercept with improved TNF neutralizing specificity and therapeutical effect, ameliorating the side effects associated to the clinical use of Etanercept.

Unmet need

The global TNF inhibitor drugs market is valued at USD 28.6 billion in 2025, projected to reach USD 46.3 billion by 2032 (CAGR 7.8%). Within this market, Etanercept (Enbrel®) is one of the leading biologics for chronic inflammatory diseases such as rheumatoid arthritis, ankylosing spondylitis or psoriasis. Importantly, up to 40% of patients exhibit inadequate response to first-line anti-TNF treatment – including Etarnecept – due to primary non-response, secondary loss of response or intolerance. Etanercept works by blocking TNF via a soluble TNFR2–Fc fusion. presenting main limitations:

▪ Dose limitations and safety constraints. Etanercept requires relatively high and repeated dosing.

▪ Non specific activity against lymphotoxin (LTα), worsening susceptibility to infections, as LTα plays an important role in host defense, particularly against intracellular pathogens.

Innovative Solution

Inspired by viral immunomodulators, next-generation etanercept variants were engineered through precise amino-acid substitutions—specifically A105E, or preferably the dual A105E/L106F modifications— introduced into the TNF-binding domain of the TNFR2-Fc fusion protein. In particular, TNFR2 90s loop— guided by insights from viral decoy receptor CrmD—avoids unwanted LTα inhibition while retaining potent TNF neutralization. Displays a >60-fold reduction in anti-LTα activity, essentially abolishing LTα inhibition, reducing undesired interactions.

Technology Highlights

1. Innovative structural improvements, preventing LTα inhibition.
2. Improved safety and manufacturability profile enabling better clinical
   performance.
