NetraMark Presents AI-Driven Advances in Precision Psychiatry to Enhance Clinical Trial Designs at Joint Autumn Conference

TORONTO, Oct. 29, 2025 (GLOBE NEWSWIRE) -- NetraMark Holdings Inc. (the “Company” or “NetraMark”) (CSE: AIAI) (OTCQB: AINMF) (Frankfurt: PF0) a premier artificial intelligence (AI) company that is transforming clinical trials with AI-powered precision analytics in the pharmaceutical industry, presented two significant applications of its technology at the International Society for CNS Clinical Trials and Methodology (ISCTM) Autumn conference and the European College of Neuropsychopharmacology (ECNP) Congress. These presentations (available on NetraMark’s website) showcase the power of NetraAI in major depressive disorder (MDD) clinical trials.

NetraAI Personas Identify Distinct Separation Between Patient Responder Subgroups

NetraMark’s first presentation, “Leveraging ML-derived patient personas to assess functional unblinding in ketamine trials for major depressive disorder”, leveraged NetraAI technology to analyze data from a randomized, crossover trial of ketamine in treatment-resistant depression.

The analysis revealed that ketamine responders had distinct baseline characteristics compared to placebo responders. Importantly, the separation between groups became clearer with repeated dosing, while within-group consistency also strengthened. These findings indicate that ketamine’s efficacy is not simply the result of functional unblinding and that distinct patient subtypes were driving response. The results point to new opportunities for persona-guided trial enrichment, stratified randomization, and patient selection strategies in clinical practice.

Ketamine & Functional Unblinding
In a Phase II ketamine trial, NetraAI revealed that responder subgroups diverged completely from placebo responders by the second infusion, while responder profiles became twice as cohesive, demonstrating ketamine’s true pharmacologic signal beyond expectancy effects.

Cross-Group Divergence: Separation between ketamine and placebo responder Personas increased from 0.75 (moderate) after the first infusion to 1.0 (complete separation) by the second infusion.
Within-Group Cohesion: For ketamine responders, cohesion rose from 25% after infusion 1 to ~67% after infusion 2, showing that responders became more internally consistent with repeated treatment.
Interpretation: These shifts demonstrate that ketamine responders are biologically and clinically distinct from placebo responders, not simply influenced by expectancy effects.

NetraAI Boosts Predictive Accuracy of Subpopulations In Heterogeneous MDD Trials

In NetraMark’s second presentation, “Sub-insight learning disentangles heterogeneous MDD trial data, boosting predictive accuracy and patient stratification for escitalopram response,” NetraMark introduced its novel algorithm to data from the CAN-BIND trial of escitalopram.

Traditional machine learning approaches struggled with prediction accuracy in this heterogeneous population. However, NetraMark’s purpose-built NetraAI identified a compact, reproducible feature set related to anhedonia and mood that improved the prediction of treatment response. It also uncovered a highly predictive responder subgroup defined by hypomethylation at three gene sites, offering biological insights into why certain patients respond more robustly to treatment. These findings demonstrate the algorithm’s potential to boost predictive accuracy, improve trial interpretability, and advance precision psychiatry by defining clinically meaningful subgroups.

Escitalopram & NetraAI (CAN-BIND Trial)

In the CAN-BIND escitalopram dataset, NetraAI reduced the amount of clinical variables, boosted prediction accuracy, and identified a subgroup of highly predictive responders.

Clinical Scale Data: Traditional machine learning (ML) applied to 718 variables showed only modest accuracy. NetraAI refined the feature set to 8 key variables (covering anhedonia, daily functioning, appetite, and negative thinking). With the “unknown” class introduced, 26 non-responders, 23 responders, and 124 unknowns were identified, leading to improved classifier performance.
Methylation Data: Among 169 patients with ~68,600 methylation variables each, NetraAI identified 33 of 117 responders as Highly Predictive Responders (HPRs).
Genetic Signature: Hypomethylation at 3 gene sites (LINC01580, STK24, ATXN7L3) linked to neuroplasticity, predicted HPRs whose treatment success could be forecast with 91% accuracy when traditional classifiers were retrained on these features.
Mechanistic Insight: These genes support synaptic remodeling, chromatin plasticity, and hippocampal neurogenesis, offering a biological explanation for treatment response.

Together, these presentations highlight the power of NetraAI to overcome long-standing barriers in CNS drug development. By separating signals from noise, uncovering responder subtypes, and mitigating bias, NetraAI can enable more efficient trials, sharper insights into drug efficacy, and better strategies for matching patients with treatments.

"The ability to distinguish true pharmacologic effects from placebo and to predict treatment response with explainable subgroups represents a meaningful advancement," said Josh Spiegel, President at NetraMark. "These findings demonstrate how our technology can transform the way psychiatric and CNS trials are designed, interpreted, and translated into clinical practice."

The Future of CNS Trial Designs Guided by AI-Powered Insights

NetraMark’s AI-driven methodologies demonstrate how explainable machine learning can reshape CNS clinical research. By enabling sharper patient stratification, reducing placebo-related noise, and improving predictive modeling, these approaches support more targeted and efficient clinical trials. As precision medicine becomes central to drug development, NetraMark’s innovations provide pharmaceutical companies and researchers with a powerful toolkit to uncover meaningful patient subgroups, accelerate development timelines, and gain deeper insight into psychiatric disorders and treatment response.

About NetraAI
In contrast with other AI-based methods, NetraAI is uniquely engineered to include focus mechanisms that separate small datasets into explainable and unexplainable subsets. Unexplainable subsets are collections of patients that can lead to suboptimal overfit models and inaccurate insights due to poor correlations with the variables involved. The NetraAI uses the explainable subsets to derive insights and hypotheses (including factors that influence treatment and placebo responses, as well as adverse events) that can significantly increase the chances of a clinical trial success. Other AI methods lack these focus mechanisms and assign every patient to a class, even when this leads to "overfitting" which drowns out critical information that could have been used to improve a trial's chance of success.

About NetraMark
NetraMark is a company focused on being a leader in the development of Generative Artificial Intelligence (Gen AI)/Machine Learning (ML) solutions targeted at the Pharmaceutical industry. Its product offering uses a novel topology-based algorithm that has the ability to parse patient data sets into subsets of people that are strongly related according to several variables simultaneously. This allows NetraMark to use a variety of ML methods, depending on the character and size of the data, to transform the data into powerfully intelligent data that activates traditional AI/ML methods. The result is that NetraMark can work with much smaller datasets and accurately segment diseases into different types, as well as accurately classify patients for sensitivity to drugs and/or efficacy of treatment.
