Prognostic value of plasma biomarkers for informing clinical trial design in mild-to-moderate Alzheimer's disease. (PubMed, Alzheimers Res Ther) - P2 | "Elevated baseline plasma NfL predicted more rapid clinical decline and MRI volume loss. Furthermore, increasing plasma NfL concentration over time was associated with worsening on the CDR-SB. Plasma NfL is an easily accessible biomarker that may enhance the design of clinical trials in mild-to-moderate AD."

A Systematic Literature Review on the Efficacy of Pharmacological Interventions in Ataxia (ISPOR-EU 2024) - "Across these, idebenone and riluzole (2 studies each) were the most commonly assessed interventions, followed by one study each for amantadine hydrochloride, deferiprone, luvadaxistat, omaveloxolone, rovatirelin, and troriluzole. Limited therapeutic options are available for ataxia, often focusing on symptomatic management rather than addressing the underlying cause. This SLR underscores a notable gap in treatments that directly target ataxia and highlights the potential pharmacological treatments in treating ataxia or slowing its progression."

Troriluzole rescues glutamatergic deficits, amyloid and tau pathology, and synaptic and memory impairments in 3xTg-AD mice. (PubMed, J Neurochem) - "Second, we sought to determine whether treatment with troriluzole, a novel 3rd generation tripeptide prodrug of the glutamate modulator riluzole, could reduce VGlut1 and glutamate release to restore cognitive deficits in 8-month-old 3xTg mice. Treatment with troriluzole reduced VGlut1 expression, decreased basal and evoked glutamate release, and restored cognitive deficits in 3xTg mice. Together, these findings suggest presynaptic alterations are early events in AD that represent potential targets for therapeutic intervention, and these results support the promise of glutamate-modulating drugs such as troriluzole in Alzheimer's disease."
