The study presented by Erin Cobain MD, Associate Professor in the Division of Hematology/Oncology at the University of Michigan Medical School, Ann Arbor and co-Principal Investigator of the SWOG S2206 Trial, titled Elucidating the immune active state of HR+HER2- MammaPrint High 2 early breast cancer [Cobain, E., et al.] characterizes the underlying immune biology that mediates immune therapy response in early stage hormone receptor-positive (HR+), Human Epidermal Growth Factor Receptor negative (HER2-) breast cancer, categorized as MammaPrint High Risk 2 (MP H2) in patients enrolled in the prospective, observational FLEX Study (NCT03053193). This study builds upon the findings from the I-SPY 2 Trial, which showed that patients with MP High-2, HR+HER2- tumors have improved response rates when immunotherapy is added to standard neoadjuvant chemotherapy.

Using whole transcriptome analysis, researchers evaluated relative frequency of immune cell types, expression level of genes involved in antigen processing and presentation, and expression of immune checkpoint genes PD-1 and PD-L1. Results of the analysis showed that MP High-2 tumors had a significantly higher frequency of antigen presenting cells (APCs) (including activated dendritic cells and macrophages, CD4+ memory T cells, CD8+ T cells, memory B cells and antibody producing plasma cells) relative to High-1 tumors, highlighting an increased immune active state in High-2 tumors. The increased antigen presentation and presence of APCs, which are critical in activating T- and B-cells, may explain why High-2 tumors display improved response rates to immunotherapy. The data from this study suggests that early stage HR+HER2- High-2 tumors might benefit from the addition of immunotherapy to their chemotherapy treatment regimens. These findings support the rationale for the ongoing SWOG S2206 (NCT06058377) Trial, which is utilizing MP High-2 as a biomarker to select patients for neoadjuvant chemo-immunotherapy treatment.

"There is a great need for biomarkers beyond PD-L1 and tumor mutational burden that may predict clinical benefit from immunotherapy-based treatments. The recent CheckMate 7FL and KEYNOTE-756 studies demonstrated that there is a subset of patients with HR+HER2- early breast cancer that will benefit from immunotherapy, as both trials demonstrated an improvement in likelihood of pathologic complete response rates for those patients receiving neoadjuvant chemo-immunotherapy compared to chemotherapy alone," said Dr. Cobain. "However, we are aiming to take this a step further and refine the biomarkers that will allow for us to identify those patients most likely to benefit from this approach and avoid overtreatment. This is particularly important given the potential serious toxicities that can result from immunotherapy treatment."

"This study highlights the importance of understanding how the classification of tumors may determine different response rates to treatment and how this will inform breast cancer care going forward. With the FLEX Study, we are now able to not only look at clinical outcomes but also analyze whole transcriptome data to better understand how women with breast cancer respond to different treatment regimens and use this information to customize breast cancer treatment," said William Audeh, MD, MS, Chief Medical Officer of Agendia. "The data we’re sharing at 2024 ASCO (Free ASCO Whitepaper) further validates MammaPrint utility in identifying not only the question of chemo vs. no chemo, but also illustrates the ability of MammaPrint to identify tumors with increased immune activation, supporting the rationale for using MammaPrint High 2 as a selective biomarker for immunotherapy in SWOG S2206."

On May 31, 2024 Artera, the developer of multimodal artificial intelligence-based prognostic and predictive cancer tests, reported that it will present three abstracts at the 2024 ASCO (Free ASCO Whitepaper) Annual Meeting demonstrating that its multimodal artificial intelligence (MMAI) platform provides significant prognostic value across various stages of prostate cancer and for early stage breast cancer (Press release, Artera, MAY 31, 2024, View Source [SID1234643917]).

"Medicine is filled with instances where the seed of an idea took years to grow into an innovative tool that changes the standard way of practice," said Andre Esteva, CEO of Artera. "Currently, cancer care strongly emphasizes biochemistry and molecular biology, and advancements can take decades to develop and adopt. Artera’s model offers a novel way of thinking, utilizing AI and image analysis to significantly fast-track innovation and advancements in cancer care, demonstrating performance across diverse patient cohorts. We are proud to be working on this new way forward."

The MMAI platform can provide results to support personalized therapy by combining a patient’s unique clinical data with their pathology slides. Artera is taking a unique approach to this by applying AI to images of hematoxylin and eosin (H&E)-stained pathology slides to provide prognostic and predictive results.

Traditionally, after a cancer diagnosis, additional insights to support a more personalized treatment plan can require multiple tests – an approach that can be expensive and hard to scale due to the complicated process of identifying and quantifying the correct genomic biomarkers across different disease states and patient populations. Artera created AI-enabled algorithms that use digitized whole slide images of the H&E slides to be able to provide personalized results in a way that can potentially boost confidence for patients and their clinicians that they are making the optimal treatment choices throughout their journey.

"Using the MMAI platform on these different groups of patients, with different types and stages of cancer, and getting clinically actionable results demonstrates just how reliable analyzing H&E slides, which are already created during the routine course of care, can be for predicting risk to personalize treatment," said Trevor Royce, MD MPH, Senior Medical Director at Artera. "This approach to cancer research has the potential to transform the future of cancer care."

This announcement follows Artera’s recent presentation at the 2024 AUA Annual Meeting, which validated the first AI-based biomarker to stratify the risk of metastasis in patients with biochemical recurrence after radical prostatectomy, showing the company’s continued commitment to extending its platform to patients at various stages of prostate cancer.

As more treatment options become available to patients, being able to personalize their treatment plan can aid in mitigating negative side effects from unnecessary treatment and increase confidence in decision-making. Artera is focused on continuing to train and validate other biomarkers using this platform, so more patients with prostate cancer at different stages, as well as other disease states such as breast cancer, will be able to use this tool that can one day personalize their treatment plans.

The data will be presented in an oral discussion by Joyce O’Shaughnessy MD, Director, Breast Cancer Research, Baylor University Medical Center, Texas Oncology and the Sarah Cannon Research Institute in Dallas, TX, Primary Investigator of the FLEX Study, titled Association of MammaPrint index and 3-year outcome of patients with HR+HER2- early-stage breast cancer treated with chemotherapy with or without anthracycline [O’Shaughnessy, J., et al.]. The FLEX study investigates the 3-year outcome of patients with HR+HER2-, genomically High Risk Luminal B-Type early breast cancer, who have undergone treatment consisting of chemotherapy with taxane and cyclophosphamide (TC) or chemotherapy with anthracycline + TC (AC-T). All patients are enrolled in the prospective, non-randomized, observational FLEX Study (NCT03053193). This study utilized both MammaPrint and BluePrint to determine tumor subtype.

Results showed that patients with MammaPrint H1 Luminal B-Type tumors demonstrated similar 3-year outcomes when treated with either TC (97.1%) or AC-T (95.3%), suggesting that patients who are classified as H1 may be able to avoid the toxicity of an anthracycline. However, patients with MammaPrint H2 Luminal B-Type tumors demonstrated a significantly higher relapse-free survival when treated with AC-T (97.7%) than with TC alone (86.4%). These findings indicate that MammaPrint H2 tumors benefit from the addition of an anthracycline to their adjuvant chemotherapy regimen.

"The ability to tailor treatment regimens to a patient’s tumor biology is crucial to optimize outcomes and quality of life. MammaPrint’s utility in guiding treatment planning is highlighted by these new data evaluating chemotherapy selection," said Dr. O’Shaughnessy. "The FLEX Study and sub-studies, such as this one, enable increased precision in identifying patients that are more responsive to specific systemic therapy regimens, and continue to aid selection of treatments for patients with HR+/HER2-negative early-stage breast cancer."

"These new findings demonstrate the strength of the FLEX research platform in evaluating the different aspects of breast cancer during its diagnosis and treatment stages, allowing for more precise and individualized treatment recommendations," said William Audeh, MD, Chief Medical Officer at Agendia. "This study offers a preliminary signal towards groundbreaking insight into MammaPrint High Risk tumors and how they best respond to chemotherapy regimens, underscoring the clinical utility of MammaPrint in the selection of treatment. We remain committed to advancing breast cancer research to help deliver the best standard of practice to women undergoing breast cancer care."

Additional data supporting MammaPrint utility in treatment selection will be presented by investigators from the ISPY2 trial in a poster titled Hormone Receptor Positive HER2-negative/MammaPrint High-2 Breast Cancer Closely Resembles Triple Negative Breast Cancer: Results from Gene Expression Data from the ISPY2 Trial [Rios-Hoyo, A., et al.]. By using data from the ISPY-2 trial, this poster demonstrates that MammaPrint H2 tumors have molecular and clinical similarities to triple negative breast cancer tumors, underscoring critical insight into how treatment plans can be optimized to achieve the best result for the patient.

Agendia will be sharing updates throughout the conference on its Twitter, Facebook and LinkedIn pages.
