Pfizer Inc. is conducting a study titled ‘Real-world Clinical Outcomes of Tucatinib, Trastuzumab, and Capecitabine Following Trastuzumab Deruxtecan for the Treatment of HER2-positive Metastatic Breast Cancer.’ The study aims to evaluate real-world outcomes such as time to next treatment, time to discontinuation, and overall survival for patients using the tucatinib-trastuzumab-capecitabine therapy after T-DXd therapy in the U.S. This research is significant as it provides insights into the effectiveness of these treatments in a real-world setting.
The study focuses on a combination of three drugs: Tucatinib, Trastuzumab, and Capecitabine. These are used in treating HER2-positive metastatic breast cancer, aiming to improve patient outcomes following previous therapy with Trastuzumab Deruxtecan.
This is an observational study using a retrospective model, meaning it looks back at existing patient data to analyze outcomes. It does not involve new patient allocation or intervention but rather examines past treatment results to understand the therapy’s effectiveness.
The study began on May 7, 2025, with its primary completion date yet to be determined. The latest update was submitted on July 28, 2025. These dates are crucial for tracking the study’s progress and ensuring timely updates for stakeholders.
This study update could influence Pfizer’s stock performance positively by showcasing its commitment to advancing cancer treatment. Investors might view this as a strategic move to strengthen Pfizer’s position in the oncology market. Competitors in the cancer treatment industry may also be closely monitoring these developments.
The study is ongoing, with further details available on the ClinicalTrials portal.
