NCT05868226
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.

A Study to Evaluate Genetic Predictors of Aromatase Inhibitor Musculoskeletal Symptoms (AIMSS)
E1Z11 is a study to determine whether certain genetic information can predict which breast cancer patients will discontinue treatment with aromatase inhibitors (AIs) due to the development of musculoskeletal symptoms (MSS). Women with stage I-III breast cancer who are prescribed the aromatase inhibitor anastrozole as treatment may join.

BYL719 and Letrozole in Post-Menopausal Patients With Hormone Receptor-Positive Metastatic Breast Cancer
This phase I trial studies the side effects and best dose of the PI3K inhibitor BYL719 when given together with letrozole in treating patients with hormone receptor-positive metastatic breast cancer. The PI3K inhibitor BYL719 may stop the growth of tumor cells by blocking some of the proteins needed for cell growth. Hormone therapy using letrozole may fight breast cancer by blocking the use of estrogen by the tumor cells. Giving the PI3K inhibitor BYL719 together with letrozole may kill more tumor cells
