Adding an Immunotherapy Drug, MEDI4736 (Durvalumab), to the Usual Chemotherapy Treatment (Paclitaxel, Cyclophosphamide, and Doxorubicin) for Stage II-III Breast Cancer
Recruiting
This phase III trial compares the addition of an immunotherapy drug (durvalumab) to usual chemotherapy versus usual chemotherapy alone in treating patients with MammaPrint High 2 Risk (MP2) stage II-III hormone receptor positive, HER2 negative breast cancer. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as paclitaxel, doxorubicin, and... Read More

A Precision Medicine Approach (SMMART-ACT) for the Treatment of Patients With Advanced Sarcoma, Prostate, Breast, Ovarian or Pancreatic Cancer
Recruiting
This phase II trial tests the how well a precision medicine approach (serial measurements of molecular and architectural response to therapy \[SMMART\])-adaptive clinical treatment \[ACT\]) works in treating patients with sarcoma, prostate, breast, ovarian or pancreatic cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). SMMART testing uses genetic and protein tests to learn how cancer changes and to understand what drug... Read More

Study to Assess Clinical Activity of Zelenectide Pevedotin in Participants With Advanced Breast Cancer
Recruiting
This is a global, multicenter, open-label study that aims to assess the efficacy and safety of zelenectide pevedotin in participants with NECTIN4-amplified recurrent, unresectable, or metastatic breast cancer who have received prior therapy (see inclusion criteria below). The study will comprise of 2 cohorts. Cohort A will include participants with hormone receptor positive/ human epidermal growth factor receptor 2 negative \[HR+/HER2-\] breast cancer, whereas Cohort B will include participants...

Study of Sacituzumab Govitecan-hziy and Pembrolizumab Versus Treatment of Physician's Choice in Patients With Triple Negative Breast Cancer Who Have Residual Invasive Disease After Surgery and Neoadjuvant Therapy (ASCENT-05/AFT-65 OptimICE-RD/GBG 119/NSABP B-63)
Recruiting
The goal of this study is to find out if the experimental product, sacituzumab govitecan-hziy (SG) in combination with pembrolizumab given after surgery, is effective and safe compared to the treatment of physician's choice (TPC) which includes either pembrolizumab or pembrolizumab plus capecitabine in participants with triple negative breast cancer that still remains after surgery and pre-surgical treatment.

Additional Support Program Via Text Messaging and Telephone-Based Counseling for Breast Cancer Patients Receiving Hormonal Therapy
Recruiting
This phase III trial compares an additional support program (text message reminders and/or telephone-based counseling) with usual care in making sure breast cancer patients take their endocrine therapy medication as prescribed (medication adherence). Medication adherence is how well patients take the medication as prescribed by their doctors, and good medical adherence is when patients take medications correctly. Poor medication adherence has been shown to be a serious barrier to effective treat... Read More

Finding an Effective Dose of GM1 to Reduce or Prevent Neuropathy (Numbness or Weakness) Due to Treatment With Paclitaxel (Phase II)
Recruiting
This phase II trial tests the safety, side effects, and best dose of monosialotetrahexosylganglioside (GM1) and whether it works in reducing or preventing chemotherapy-induced peripheral neuropathy (CIPN) in patients with breast cancer that has spread from where it first started (primary site) to other places in the body (metastatic) who are receiving treatment with paclitaxel. Chemotherapy drugs, such as paclitaxel, work in different ways to stop the growth of cancer cells, either by killing th... Read More

Testing Low Dose Tamoxifen for Invasive Breast Cancer, the (LoTam) Trial
Recruiting
This phase III trial compares the effect of low dose tamoxifen to usual hormonal therapy, including aromatase inhibitors, in treating post-menopausal women with hormone positive, HER2 negative early stage breast cancer. Tamoxifen is in a class of medications known as antiestrogens. It blocks the activity of estrogen (a female hormone) in the breast. This may stop the growth of some breast tumors that need estrogen to grow. Aromatase inhibitors, such as anastrozole, letrozole, and exemestane, pre... Read More

Recruiting
The phase III trial compares the effect of pembrolizumab to observation for the treatment of patients with early-stage triple-negative breast cancer who achieved a pathologic complete response after preoperative chemotherapy in combination with pembrolizumab. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. This trial may help researchers determine if observa... Read More
