Symposium Abstract:
Over the past 20-30 years, schizophrenia research has increasingly focused on identifying novel pathophysiological mechanisms that may enable the development of new chemical entities (NCEs) with primary mechanisms of action distinct from dopamine D2 receptor antagonism, which remains the common mechanism shared by more than 40 antipsychotics currently available worldwide. These strategies have involved numerous targets i.e. glutamatergic, cholinergic signalling, neuroplasticity, serotonin modulation and inflammatory mechanisms.
This increasing interest stems from the fact that approximately 30% of individuals living with schizophrenia do not respond to first- or second-generation antipsychotics (APs), meeting criteria for treatment-resistant schizophrenia (TRS) during the course of the illness. Moreover, a subset of these patients shows an inadequate response to antipsychotic treatment from the onset of the disease.
Chairperson Prof. Dr. med. P. Falkai (Ludwig Maximilian University of Munich, Germany)
Introduction: Despite advances in the development of novel antipsychotics, treatment-resistant schizophrenia (TRS) remains without an effective treatment
Speaker Prof. Dr. med. P. Falkai (Ludwig Maximilian University of Munich, Germany)
will explore the most recent advances that have led to the development of novel atypical antipsychotics, with a particular focus on glycine re-update inhibitors and other drugs involved in glutamatergic mechanism pathways.
The need for new mechanisms of antipsychotic drugs to develop therapeutic strategies to reduce progression of schizophrenia and treat key symptoms of the disease
Speaker Prof. Marco A. Riva, PhD University of Milan, Italy
will review recent progress in the development of innovative pathways and treatments for schizophrenia, summarizing the most promising findings to date in animals.
Neurodevelopmental hypothesis for schizophrenia
Speaker Prof. A. Grace, PhD (University of Pittsburgh, USA)
will discuss why currently available antipsychotics primarily target positive symptoms of schizophrenia and will highlight limbic hippocampal hyperexcitability as a compelling therapeutic target.
1H-MRS neurometabolite markers of antipsychotic response in psychosis: A mega-analysis
Speaker Prof. A. Egerton, PhD (King’s College London, UK)
will present findings from a mega-analysis of 1H-MRS neuro-metabolite markers associated with antipsychotic response in psychosis.
Unique preclinical effects of evenamide predict benefits in patients with inadequate response and treatment-resistant schizophrenia (TRS)
Speaker R. Anand, MD (Chief Medical Officer, Newron Pharmaceuticals)
will present evidence demonstrating how the preclinical effects of evenamide translate into clinical benefits for patients with inadequate treatment response and those with treatment-resistant schizophrenia.
Discoveries leading to the development of new atypical antipsychotics
Emerging Insights Into Schizophrenia Neurobiology: Beyond Dopamine Blockade
This session will examine how advances in nondopaminergic mechanisms of action are potentially redefining our therapeutic approach to schizophrenia. Discussion of the neurobiology underlying interactions between novel mechanisms and relevant neural circuits will include consideration of the investigational work still needed to fully elucidate impacts beyond control of positive symptoms and psychosis and into negative and cognitive symptoms. The session will also consider the neurobiological and outcome consequences of the polypharmacy burden often observed with current schizophrenia treatment regimens, including the growing evidence that adjunctive agents used to manage treatment side effects may be detrimental to patient outcomes.

Uncovering the Everyday Burden of GAD & MDD
This symposium will explore the real-world burden of Generalized Anxiety Disorder (GAD) and Major Depressive Disorder (MDD), focusing on their impact on patients’ daily functioning and quality of life. Expert speakers will address the need to move beyond symptom control in GAD toward restoring functional outcomes and will examine the role of comorbidities in depression management. The session will provide practical insights into patient-centered care and highlight challenges faced in routine clinical practice.

The Neurobiology and Pharmacologic Treatment of Stuttering
Stuttering is a neuropsychiatric disorder classified in DSM. Stuttering has been reported throughout recorded human history and every language describes stuttering. The disorder typically begins in childhood yet now multiple etiologies have been postulated. Stuttering affects over 4% of children and persists to affect over 1% of all adults. In spite of its persistence and prevalence, therapeutics remain limited with no regulatory approvals of any treatments. STARS was founded just last year and is the first non-profit society dedicated to improving the lives of persons who stutter through advancements in neuroscience research and associated therapies. Both Dr. Maguire and Dr. SheikhBahaei are persons who stutter themselves and serve as volunteer founders of STARS. They will describe what advancements have been identified in the neurobiologic understanding of stuttering and what directions are now clearer in delivering effective neuropsychopharmacologic treatments to this large global community that faces significant unmet medical needs.

NCNP-CINP Co-Sponsored Symposium: Advancing Addiction Research from Japan
The National Center of Neurology and Psychiatry (NCNP), Japan’s leading institution for mental health and neuroscience, plays a central role in advancing addiction research through an integrated approach spanning basic neuroscience, clinical research, and public health.
Addiction remains a major global challenge, influenced by complex interactions among genetic, environmental, and social factors. In Japan, unique characteristics of addiction—such as genetic backgrounds affecting alcohol metabolism and sociocultural patterns of substance use—provide valuable opportunities for scientific discovery.
NCNP is promoting a large-scale addiction research initiative supported by national funding, aiming to:
- Elucidate neurobiological mechanisms of addiction
- Identify genetic and environmental risk factors
- Develop biomarkers for diagnosis and treatment
- Promote translational research from bench to bedside
- Development and dissemination of a psychosocial approach
- Contribute to international collaborative research
This symposium highlights cutting-edge research from NCNP, including organoid-based disease modeling, genetic studies, and neuropharmacological approaches, and aims to strengthen global collaboration in addiction research.
