NCT07683754

T-DXd Based Therapy Followed by Endocrine Therapy Plus Dual HER2 Blockade in First-line HER2+/ HR+ Metastatic Breast Cancer and Retreatment With T-DXd

This study will evaluate a structured sequential treatment strategy starting with T-DXd + pertuzumab upfront therapy, followed by an optimized maintenance therapy with dual HER2+blockade + CDK4/6i + ET and the opportunity to retreat with T-DXd once patients progress under maintenance aimed to maximizing disease control, optimizing tolerability, and preserving T-DXd as a future therapeutic option, while ensuring participant safety and regulatory compliance in participants with HER2+/HR+ advanced/metastatic breast cancer.

PRE-ISPY Phase I/II Oncology Platform Program

PRE-ISPY Phase I/II (I-SPY-P1) is an open-label, multisite platform study with multiple ongoing drug regimen arms added by protocol amendment which is designed to evaluate single agents or combinations in locally advanced, incurable, or metastatic solid tumors and/or oligometastatic malignancy and/or a high risk of recurrence following prior treatment with curative intent. The overall goal is moving promising drug regimens into a larger phase II (or III) trial and in general could feed the neoadjuvant breast I-SPY 2 Trial (NCT01042379) and/or other oncology solid tumor trial in a timely manner.

Pragmatic Study to Optimize Neoadjuvant Treatment and Surgical De-escalation in HR+/HER2- Early Breast Cancer Using Oncotype DX and Abemaciclib

This is a pragmatic phase 2 study to determine the proportion of patients with ER+ (≥10%)/HER2- EBC in whom neoadjuvant chemotherapy can be replaced by NET plus abemaciclib based on the results of the ODX RS obtained in the initial diagnostic biopsy and according to the MDT decision and to evaluate the proportion of patients undergoing breast conservative surgery and/or sentinel node biopsy
