AC Immune Releases New ALS Biomarker Data from Phase 1 Trial
- Clinical Trial Progress: AC Immune SA presented preliminary data on the TDP43-PET tracer ACI-19626 at the 2026 Summit Advancing TDP43 Biomarkers, indicating higher uptake in ALS patients, suggesting its potential in diagnosing neurodegenerative diseases.
- Biomarker Exploration: TDP-43 is a key component associated with diseases like frontotemporal dementia and amyotrophic lateral sclerosis, and the development of the ACI-19626 tracer aims to visualize TDP-43 markers via PET scanning, providing new solutions for complex disease diagnoses.
- Trial Design: The Phase 1 trial for ACI-19626 consists of two parts, with the first part involving healthy patients and the second enrolling up to 30 patients with FTD, ALS, and LATE, where preliminary results show significantly higher tracer uptake in ALS patients, validating the effectiveness of the PET data.
- Pharmacokinetic Profile: The study also established the pharmacokinetic profile of ACI-19626, confirming its suitability for human brain imaging, laying the groundwork for future clinical applications.
