New Insights on Therapy Sequencing for Breast Cancer Patients from Caris Life Sciences

A recent study conducted by Caris Life Sciences, a prominent player in AI-driven precision medicine, sheds light on the optimal sequencing of treatments for breast cancer patients. The research, published in the journal Breast Cancer Research, focuses on the comparative effectiveness of two antibody-drug conjugates (ADCs), trastuzumab deruxtecan (T-DXd) and sacituzumab govitecan (SG), particularly in patients with HER2-negative breast cancer.

Key Findings

The study highlighted that T-DXd proved more effective for patients whose tumors are hormone receptor (HR)-positive. These patients were able to maintain their treatment longer compared to those administered SG across all HER2-negative classifications. However, the scenario changes for patients with HR-negative and HER2-null tumors; in these cases, SG demonstrated superior outcomes when given as the initial treatment. Interestingly, for other patient demographics, the research found no significant advantage to prioritizing one drug over the other.

George W. Sledge, Jr., MD, who serves as the executive vice president and chief medical officer at Caris, emphasized the importance of real-world evidence in understanding treatment dynamics, especially due to the lack of direct comparative trials between these common ADCs. “In the absence of head-to-head trials, our real-world evidence provides vital insights into treatment effectiveness and scheduling,” he stated.

Caris Life Sciences utilized an extensive database consisting of over 4,000 patients to derive these findings, which could significantly aid healthcare providers in selecting the most suitable treatment options tailored to their patients’ needs. Furthermore, the results indicated that T-DXd and SG offered comparable advantages in patients battling triple-negative breast cancer, underscoring the essence of personalized treatment strategies based on specific tumor characteristics.

The Importance of Real-World Data

David Spetzler, MS, PhD, MBA, president of Caris, acknowledged the pivotal role of their vast real-world data in generating clinically relevant insights. He stated, “Caris is at the forefront of precision medicine, harnessing advanced AI and real-world data to facilitate personalized care. Our innovation is reshaping the intersection of science and treatment.”
