The goal of this trial is to see if active surveillance monitoring and hormonal therapy in patients diagnosed with ductal cell carcinoma in situ (DCIS), an early stage of breast cancer, can be an effective management of the disease.
Participants will be asked to receive control hormonal therapy or an investigational hormonal therapy treatment. Participants will be asked to return for evaluation with MRI at three months and six months. Depending on the evaluation participants will have the option to continue on the treatment. If the evaluation suggests surgery is recommended, the participant will discontinue the study treatment and will undergo surgery. In addition to the treatment and MRI evaluation, participants will be asked to provide blood sample to understand their immune status, provide saliva sample for genetic testing, provide the study with a portion of the tissue or slides generated from tissue removed during surgery performed as part of their standard of care.

I-SPY Phase I/Ib (I-SPY-P1) is an open-label, multisite platform study designed to evaluate single agents or combinations in a metastatic treatment setting that may be relevant for breast cancer patients with the overall goal of moving promising drug regimens into the I-SPY 2 SMART Design Trial (NCT01042379) and/or other oncology-based trials in a timely manner.

This is an open-label, single-arm, multi-site phase I/Ib trial with SYD985, an antibody-drug conjugate (ADC) targeting HER2 on the cell membrane, combined with paclitaxel.
