Administration of a Novel Peptide Derived From Thrombospondin Repeat Sequences Enhances Recovery after Cervical Spinal Cord Injury. (PubMed, J Neurotrauma) - "Furthermore, for animals that were treated daily with NX210c starting 8 h post-injury, histological analysis demonstrated greater white and gray matter preservation and reduced cavity size, along with the upregulation of neuronal markers. To conclude, NX210c mitigates various aspects of SCI, including motor function and tissue preservation, with preferential results being obtained with the delayed initial administration of NX210c at 8 h post-injury."

NX210c for recovering Blood Brain Barrier integrity in ALS patients: in silico modelling complements statistical analysis of fluid biomarkers for dose selection and design of a phase II study (ALS-MND 2024) - "Safety results of 29 subjects showed NX210c has a good safety profile with all but one of the treatment emergent adverse events being mild (1 moderate) and no significant neurotoxicity. Statistical analysis of blood and cerebrospinal fluid (CSF) biomarkers demonstrated significance or trend(s) for change. Further PK/PD modelling methods identified relationships between NX210c PK and plasma biomarkers, with claudin-5, homocysteine, neurofilament light chain and SPARC-like protein 1 (SPARCL1) among them."

NX210c drug candidate peptide improves motor function and prolongs survival in the SOD1G93A mouse model of ALS (ALS-MND 2023) - "The orientation, travel and total times during the static rods test were higher in SOD1G93A mice compared with WT mice from 16 weeks old until disease end-stage (p < 0.001). A dose-dependent improvement of motor performances was observed in SOD1G93A mice treated with NX210c. More particularly, the peptide at 10 mg/kg reduced ALS-induced increased orientation and travel times from 16 weeks old (WT: 1.3 and 3.2s, vehicle SOD1G93A: 24.5s and 26.6s and 5.4s, NX210c SOD1G93A: 2.6 and 4.8s for orientation and travel times, respectively; p < 0.01) until disease end-stage on the largest diameter rod."

NX210c drug candidate peptide improves motor function and prolongs survival in the SOD1G93A mouse model of ALS (Neuroscience 2023) - "Overall, NX210c is a new promising drug candidate and its solid preclinical package (mechanism of action, proof of concept in ALS) should support the clinical development of NX210c in ALS patients. In addition, we have gathered several proofs of concept showing that NX210c restores cognitive functions (Lemarchant et al., 2022; Le Douce et al., 2021), which may represent a supplementary beneficial effect of NX210c for ALS patients, since 35% of them suffer from cognitive or behavioral impairments, with an additional 15% having FTD."
