Concurrent WOKVAC Vaccination, Chemotherapy, and HER2-Targeted Monoclonal Antibody Therapy Before Surgery for the Treatment of Patients With Breast Cancer
Recruiting
This phase II trial studies the immunologic response and side effects of using the WOKVAC vaccine in combination with chemotherapy and HER2-targeted monoclonal antibody therapy before surgery in treating patients with breast cancer. Vaccines like WOKVAC are made from tumor-associated antigens which may help the body build an effective immune response to kill tumor cells. Chemotherapy drugs, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells,... Read More

A Study of Disitamab Vedotin With Other Anticancer Drugs in Solid Tumors
Recruiting
This clinical trial is studying solid tumor cancers. A solid tumor is one that starts in part of your body like your lungs or liver instead of your blood. Once they've grown bigger in one spot or spread to other parts of the body, they're harder to treat. This is called advanced or metastatic cancer. Participants in this study must have breast cancer or gastric cancer. Participants must have tumors that have HER2 on them. This allows the cancer to grow more quickly or spread faster. There are f... Read More

Study of the CHK1 Inhibitor BBI-355, an ecDNA-directed Therapy (ecDTx), and the RNR Inhibitor BBI-825, in Subjects With Tumors With Oncogene Amplifications
Recruiting
BBI-355 is an oral, potent, selective checkpoint kinase 1 (or CHK1) small molecule inhibitor in development as an ecDNA (extrachromosomal DNA) directed therapy (ecDTx). BBI-825 is an oral, potent, selective ribonucleotide reductase (or RNR) small molecule inhibitor. This is a first-in-human, open-label, 2-part, Phase 1/2 study to determine the safety profile and identify the maximum tolerated dose and recommended Phase 2 dose of BBI-355 administered as a single agent or in combination with BBI-8...

A Digital Health Intervention to Improve Symptoms and Physical Activity During Breast Radiation
Recruiting
This clinical trial evaluates a digital health intervention for improving symptoms and physical activity among patients with breast cancer undergoing radiation. Cancer-related fatigue is common and strongly associated with quality of life during and after treatment. Increasing emphasis on early symptom detection and management has prompted initiatives to collect patient-reported fatigue from all patients during treatment. Mind-body interventions including physical activity and yoga are recommend... Read More

Effect of HSD3B1 (1245C) Gene Mutation on Treatment of Stage I-III Breast Cancer
Recruiting
This stage IV trial examines how a mutation in HSD3B1 (1245C) gene affects treatment of stage I-III breast cancer. This trial may help researchers determine if mutations in HSD3B1 decreases the efficacy of aromatase inhibitor therapy such as letrozole. Letrozole may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
