Summary: Researchers plan to study the natural history of ado-trastuzumab emtansine (T-DM1)-induced neuropathy both in patients without any history of neuropathy or previous neurotoxic agent use and in patients who have such a history.

Summary: This research study is studying how well newly diagnosed breast cancer that has tested positive for a protein called HER2 responds using one of two different combination of HER2-directed therapies as a treatment after surgery. The name of the study drugs involved are: * Trastuzumab-emtansine (T-DM1, Kadcyla) * Trastuzumab SC (Herceptin Hylecta) * Paclitaxel

Summary: This is a Phase IB/II multi-cohort study designed to evaluate the efficacy and safety of targeted agents with or without cancer immune checkpoint therapy with atezolizumab in participant with recurrent and/or persistent endometrial cancer. The main protocol provides a platform for genomic screening with homogeneous basic eligibility criteria in order to direct study participants into biomarker-mat...

Summary: This is a Phase Ib/II, open-label, multicenter, randomized umbrella study in participants with breast cancer. The study is designed with the flexibility to open new treatment arms as new treatments become available, close existing treatment arms that demonstrate minimal clinical activity or unacceptable toxicity, or modify the patient population. Cohort 1 will focus on participants with inoperable...

Summary: The purpose of this study is to further advance the ability to practice personalized medicine by learning which new drug agents are most effective with which types of breast cancer tumors and by learning more about which early indicators of response (tumor analysis prior to surgery via magnetic resonance imaging (MRI) images along with tissue and blood samples) are predictors of treatment success.

Summary: To learn if the study drugs, tucatinib and adotrastuzumab emtansine (T-DM1), can help to control solid tumors that have spread to the brain.

Summary: The purpose of this study is to test the safety and effectiveness of a sequence of drugs (a Taxane plus Trastuzumab plus Pertuzumab followed by Trastuzumab Deruxtecan, followed by Tucatinib plus Ado-Trastuzumab Emtansine (T-DM1), followed by Trastuzumab plus Pertuzumab plus Tucatinib) in HER2+ Breast Cancer. The study will help investigators understand whether first intensifying therapy for a spec...

Summary: Trastuzumab is an important treatment for HER 2 positive breast cancer. But trastuzumab can cause injury to the heart, and this is one of the main reasons it cannot be administered as planned. Heart injury can often be successfully treated using cardiac medications. The objectives of SCHOLAR-2 are to evaluate whether is it safe and effective to continue trastuzumab, pertuzumab or trastuzumab-emtan...

Summary: This research is being done to see how safe and effective the use of the study drug Ado-trastuzumab (T) emtansine (DM1), T-DM1, and standard of care chemoradiation are when used together in treating HER2-positive salivary gland cancer. It will also examine the effectiveness of study drug Ado-trastuzumab (T) emtansine (DM1) on cancer recurrence.

Summary: This is a Phase 2 study for patients with resected Stage I-III HER2+ breast cancer with detected molecular residual disease (MRD+) following standard neoadjuvant and locoregional therapy delivered with curative intent. In this study Patients will be treated with neratinib in addition to their standard T-DM1 adjuvant therapy. Neratinib will be administered orally at a dose of 160 mg daily for up to...

Summary: This phase III trial studies how well trastuzumab emtansine (T-DM1) and tucatinib work in preventing breast cancer from coming back (relapsing) in patients with high risk, HER2 positive breast cancer. T-DM1 is a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug, called DM1. Trastuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the s...

Summary: This study is designed to compare the anti-tumor activity as well as the safety and efficacy of FS-1502 versus T-DM1 in HER2-positive, unresectable locally advanced or metastatic breast cancer subjects previously treated with trastuzumab and taxane.
