NETRAMARK HOLDINGS INC. — Insights open the door for potential precision immunotherapy innovation targeting novel pathways and patient enrichment strategies with the potential to improve clinical trial success rates —
"These findings add to the growing body of evidence demonstrating that NetraAI can extract meaningful insights from small datasets, offering an alternative approach to stratify patients while not reinforcing our current knowledge and belief biases about patient populations," said
Both posters were presented in the "
The poster titled "NetraAI-driven discovery of novel biomarkers in MSI-high colon cancer for precision immunotherapy" (Abstract #LB395) describes the use of Attractor AI algorithms to identify causal clusters of variables (hypotheses) that explain specific sub-populations of patients with microsatellite instability-high (MSI-H) CRC. MSI-H tumors are characterized by an extensive mutational load, which fosters the production of neoantigens and amplifies immune visibility, making them prime candidates for immunotherapy. However, these same factors contribute to heterogeneity that further complicates the efficacy of targeted therapies. NetraAI was applied to a data set consisting of tens of thousands of RNA expression variables from 390 samples from CRC patients. These profiles included 44 MSI-H and 21 MSI-low (MSI-L) samples and the dataset used consisted of a total of 22,283 variables. Key findings from the analysis include:
- In one NetraPerspective, there was a MSI-H subpopulation identified, consisting of 29 MSI-H and 2 MSI-L samples. This subpopulation is characterized by expression of CATSPERB (p=1.2 x 10-7), MLPH (p=4.9 x 10-5), FUT8 (p=8.6 x 10-5), DUSP4 (p=1.1 x 10-3), and PLLP (p=0.01).
- Constructing PPI networks based on the identified variables suggests a complex interplay among them, particularly in the context of spermatogenesis.
- Mismatch repair (MMR) is essential for ensuring genetic integrity during sperm production. The findings of the NetraAI analysis suggest that defects in MMR play a causal role in the genetic instability seen in MSI-H CRC.
- The specificity of CATSPERB to an MSI-H colon cancer subgroup posits it as a potential biomarker for identifying patients who might benefit from tailored therapeutic approaches, contributing to the personalized medicine landscape.
- CATSPERB protein is primarily associated with calcium channels in sperm, but its over-expression in a subset of MSI-H CRC patients suggests that the protein may modulate calcium signaling in tumor cells, which is known to play a role in a variety of cellular processes that drive cancer cell proliferation, survival, and metastasis.
The poster titled "The power of NetraAI: Precision medicine in oncology through sub-insight learning from small data sets" (Abstract #LB396) describes the use of Attractor AI algorithms to identify variables defining specific subpopulations of patients with NSCLC. A small data set consisting of 104 gene expression samples of adenocarcinoma (ADC) and squamous cell carcinoma (SSC) was compiled from two NSCLC datasets. Key findings from the analysis include:
- One NetraPerspective showed multiple explainable subpopulations of NSCLC, primarily stratified as ADC or SCC subpopulations. Interestingly, there were multiple subpopulations of each subtype suggesting that different combinations of variables drive specific ADC and SCC subtypes.
- Examination of each subpopulation using NetraAI's unique zoom capabilities of NetraAI, identified the specific patients and characterizing variables.
- In one NetraPerspective, NetraAI distinguished between ADC and SCC subtypes through unique genetic signatures, with 9 out of 10 variables correlating with known NSCLC markers. This validates the methods and technology used by NetraAI.
- PIGX emerged as a novel target due to its previously unexplored role in cancer biology.
- Further investigation into PPI networks revealed a significant connection between PIGX and BACE1, a protein implicated in NSCLC brain metastasis. This opens new avenues for understanding molecular mechanisms underlying cancer progression and metastasis.
- PIGX is also related to PIGN which is associated with genomic instability and regulates spindle assembly checkpoint proteins in leukemia transformation and progression.
"The demand for personalized oncology treatment strategies necessitates novel AI/ML technologies that can leverage smaller or limited datasets to uncover actionable insights," added
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.
