– Lunit’s AACR 2024 presentations to spotlight HER2 mutation insights and CNTN4’s role in immunotherapy success, pioneering next-gen personalized treatment approaches, supported by the AI-powered Lunit SCOPE suite
SEOUL, South Korea, April 1, 2024 /PRNewswire/ — Lunit (KRX:328130.KQ), a leading provider of AI-powered solutions for cancer diagnostics and therapeutics, today announced the presentation of seven studies at the American Association for Cancer Research (AACR) 2024 Annual Meeting in San Diego, California, from April 5 to 10.
Lunit to Showcase 7 Studies at AACR 2024
In a poster presentation, Lunit’s AI-powered HER2 analyzer, Lunit SCOPE HER2’s precision shines through its analysis of 194,259 pan-cancer samples, correlating different ERBB2 mutations with changes in HER2 protein expression. This AI-powered assessment successfully identified key mutation-expression correlations, particularly focusing on exon 20 insertions (ex20ins) and S310x mutations across a variety of cancers, including NSCLC, urothelial, and breast cancers.
Through detailed HER2 intensity examination, the AI analysis highlighted that, among ERBB2-mutated cases with HER2 IHC images, a higher proportion of HER2 3+ tumor cells was observed in S310x and ex20ins cases compared to others. Similarly, high HER2 expression was observed in both S301x and ex20ins cases compared to other mutation cases. The findings suggest that understanding these mutation-expression relationships could improve the prediction of treatment responses, enabling a step forward in the development of more personalized and precise therapeutic strategies for cancer patients with ERBB2 mutations. The study also indicates the potential of AI in enhancing the precision of cancer treatment through the identification of genetic alterations that influence protein levels.
In a collaborative study with Genome & Company, a clinical-stage biotechnology specializes in anti-cancer therapeutic development, Lunit leveraged its AI-powered immunohistochemistry (IHC) analyzer to investigate the expression of Contactin-4 (CNTN4) and its relationship with PD-L1 across 18 types of cancers. CNTN4, which is mainly expressed in tumor cells, is known to reduce T-cell activation and responsiveness to tumors.
The analysis of 795 pan-cancer tissue samples revealed an important inverse correlation between CNTN4 expression and PD-L1 levels. When PD-L1 intensity was ≥ 30%, 50%, 75%, and 90%, CNTN4 was observed in 42.4% (337/795), 25.5% (203/795), 11.4% (91/795), and 5.2% (41/795) of cases, respectively. This insight positions CNTN4 as a promising target for immunotherapy, particularly in cancers that exhibit low PD-L1 expression.
Another study conducted with Genome & Company focused on the correlation between the efficacy of pembrolizumab treatment and CNTN4 expression in gastric cancer patients. This study categorized patients based on CNTN4 and PD-L1 expression levels. The results indicated that patients with low CNTN4 expression and high PD-L1 levels were more likely to respond favorably to pembrolizumab, showing a 64.3% objective response rate (ORR). Conversely, patients exhibiting both high CNTN4 and PD-L1 expression demonstrated a 0% ORR, with non-responders presenting lower PD-L1 expression and higher CNTN4 levels compared to responders. These findings not only highlight CNTN4’s potential as a predictive biomarker for immunotherapy response but also underscore the pivotal role of AI-powered analytics in identifying novel biomarkers.
"We are excited to present our groundbreaking studies at AACR 2024, illustrating the profound impact of the Lunit SCOPE suite on cancer research and treatment," said Brandon Suh, CEO of Lunit. "Our findings, particularly the discovery of key mutation-expression correlations by Lunit SCOPE HER2 and the potential of CNTN4 as a novel biomarker for immunotherapy responsiveness, underscore our commitment to transforming cancer care. These studies not only highlight our pioneering role in leveraging AI to enhance precision medicine but also pave the way into the future of oncology – where treatment is not just personalized but predictive, ensuring the best possible outcomes for patients worldwide. We’re proud to contribute to this transformative journey, marking a significant milestone in our mission to fight cancer with AI."
In addition to the studies above, Lunit will present four more studies at this year’s AACR, showcasing the diverse capabilities of Lunit SCOPE IO, Lunit SCOPE HER2, and an AI-based CT image analyzer combining analysis of CT scans with digital pathology analysis to predict response to checkpoint therapy.
