Biomarker, Clinical, Observational data, Retrospective data, Review, Journal: Therapeutic potential of D-amino acid oxidase inhibitors for cognitive impairment associated with schizophrenia: learnings from luvadaxistat. (Pubmed Central) - Jan 12, 2025 In this review, we provide an overview of the evidence supporting the potential of NMDAR modulators in general, and DAAO inhibitors in particular, as potential adjunctive treatments for schizophrenia. We also discuss the preclinical and clinical data related to luvadaxistat, an investigational highly selective and potent DAAO inhibitor that was under development for the treatment of the cognitive impairment associated with schizophrenia.

PK/PD data, Review, Journal: Finding the right dose: NMDAR modulating treatments for cognitive and plasticity deficits in schizophrenia and the role of pharmacodynamic target engagement. (Pubmed Central) - Dec 11, 2024 A range of direct and indirect NMDAR modulators will be covered, including d-serine, d-cycloserine, memantine, glycine and "first generation" glycine transport inhibitors (GTI, e.g. sarcosine and bitopertin), as well as recent positive studies of iclepertin, a novel GTI and luvadaxistat, a D-amino acid oxidase inhibitor (DAAO-I) that increases brain d-serine levels and indirect non-invasive brain stimulation NMDAR modulating treatments. Several examples of successful use of pharmacodynamic target engagement biomarkers for dose/drug discovery will be emphasized, including mismatch negativity (MMN), auditory steady state (ASSR) and time-frequency event-related potential (TF-ERP) approaches.
- |||||||||| A Systematic Literature Review on the Efficacy of Pharmacological Interventions in Ataxia () - Nov 4, 2024 - Abstract #ISPOREU2024ISPOR_EU_1292;
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.

Some molecules that are currently being investigated in Phase 2 and Phase 3 trials have provided very promising preliminary results, but more information is currently required to assess their effectiveness in real-world contexts and to provide clear recommendations regarding their use in clinical practice. The results of ongoing and future studies will reveal whether any of these molecules represents the awaited pharmacological game-changer in the treatment of CIAS.

Meta-Analysis of Adjunctive Treatment Trials for Cognitive Deficits in Schizophrenia (Griffin Hall) - Apr 14, 2024 - Abstract #SOBP2024SOBP_413; Overall effect sizes were similar across MoA, suggesting that significance for NMDAR modulators is presumably driven by the larger number of studies. Nevertheless, effect sizes were generally small, suggesting possible ceiling effects or the need for combined behavioral/pharmacological treatments.

Novel efficacious drugs should be investigated that aim to improve symptoms or slow disease progression.

Regional Comparison of Paired Ratings in a Study of Negative Symptom Schizophrenia () - Mar 11, 2022 - Abstract #SIRS2022SIRS_942; P2 Bland-Altman scatterplots revealed that 4.8% of paired PANSS scores and 4.7% of paired BNSS scores were outside the confidence intervals. For all pairs, the site-based mean total BNSS and PANSS scores were significantly lower than the paired site-independent scores (p<0.0001 and p= 0.006 respectively).
