Active clinical trials for "Breast Neoplasms"

This research study is studying a drug combination of nivolumab and ipilimumab as a possible treatment for hypermutated HER2 negative breast cancer. The drugs involved in this study are: Nivolumab (Opdivo ®) Ipilimumab (Yervoy ®)

The primary objective of this study is to assess and compare the efficacy and safety of sacituzumab govitecan-hzi versus treatment of physician's choice (TPC) in participants with hormonal receptor-positive (HR+) human epidermal growth factor receptor 2 (HER2-) negative metastatic breast cancer (MBC).

Approximately 3.5% to 6% of newly diagnosed breast cancer patients are stage IV metastatic. De novo metastatic breast cancer accounts for 20% to 25% of these cases. Despite a decrease in mortality in Europe and North America due to early detection and access to treatment, breast cancer remains the 2ⁿᵈ leading cause of cancer deaths in developed countries after lung cancer and the world's leading cause. In the ESME French national retrospective cohort (NCT03275311), the newly diagnosed estrogen receptor (ER)-positive and HER2-negative (luminal) metastatic patients had a 59.1 months overall survival (OS) for pre-menopausal women and 44.7 months for postmenopausal women. In the same cohort, the median OS was 47.4 months for de novo metastatic patients with hormone receptor (HR)-positive / HER2-negative breast cancer. The most important current treatment for metastatic breast cancer remains systemic therapy. Surgery and radiation are mainly used to treat symptoms. However, more than 15 retrospective studies have assessed the impact of locoregional treatment on relapse and OS. These studies suggested an improvement of the OS in patients with de novo metastatic breast cancer thanks to the addition of locoregional treatment to systemic therapy. Recent data from the ESME cohort suggest that patients with de novo luminal or HER2-positive metastatic breast cancer may benefit from local treatment of the primary tumor. Several prospective trials have attempted to demonstrate the benefit of locoregional treatment with mixed results. This can be explained by a limited power of statistical analysis, on the recruitment of patients with breast cancer of all types, and on a limited access to effective systemic therapies in some cases and all before the area of anti CD4/6 which is the current standard treatment in patients with HR-positive / HER2-negative luminal metastatic disease. However, guidelines indicate that a "multimodal approach, including curative locoregional treatments, should be considered". As a result, many clinicians offer locoregional treatment of the primary tumor, especially if there is a good response to the first line of systematic treatment. Taken together, these data underscore the need for an evaluation of the value of combined therapy - endocrine therapy - CDK4/6 inhibitor and locoregional treatment - in this population of patients with newly diagnosed HR-positive / HER2-negative breast cancer.

Eligible patients with estrogen receptor positive breast cancer will undergo a biopsy and be randomized to receive endocrine therapy (ET) versus endocrine therapy with palbociclib (PET) in a 1:2 ratio. After 1 cycle (28 days) another biopsy will be obtained, and both arms will receive avelumab (A) for 3 additional cycles. Patients will then undergo breast surgery.

The combination of chemotherapy with PD-1 immune checkpoint blockade agents demonstrated promising results especially in the neo-adjuvant and early metastatic setting in TNBC. However, a substantial proportion of patients do not derive benefit from this approach. CD73 is an adenosine-generating enzyme overexpressed in several cancers and associated with poor prognosis and reduced anti-tumor immunity in TNBC. Monoclonal antibodies directed against CD73 could help to reprogram the tumor microenvironement by decreasing the adenosine mediated immunosuppression, particularly as a synergistic immunotherapeutic combination with immune checkpoint blockade. The SYNERGY trial investigates the role of an anti-CD73 (MEDI9447) in a randomized phase II trial evaluating the efficacy and safety of the combination of chemotherapy (paclitaxel + carboplatin) with immunotherapy (durvalumab [anti-PD-L1] +/- MEDI9447 [anti-CD73]) in previously untreated locally recurrent inoperable or metastatic TNBC. A large translational research program is planned including baseline and dynamic biomarkers

2X-121 is a small molecule targeted inhibitor of Poly ADP ribose polymerase (PARP), a key enzyme involved in DNA damage repair in cancer cells. The PARP inhibitor demonstrated clinical activity in a prior Phase 1 study in a number of solid tumors. 2X-121 has a novel dual-inhibitory action against both PARP 1/2 and Tankyrase 1/2. The molecule is also active in P-glycoprotein expressing cells, suggesting it may overcome some of the PARP inhibitor resistance. The Phase 2 study is using 2x-121 DRP® biomarker in metastatic breast cancer patients to identify patients likely to respond to and benefit from treatment with 2X-121.

REaCT ZOL will compare one 4 mg dose of Zoledronate vs. one 4 mg dose of Zoledronate given every 6 months for 3 years.

The purpose of this study is to determine in a phase II clinical trial whether accelerated partial breast irradiation after breast conserving surgery using 3 dimensional external beam radiotherapy (3D-CRT) and intensity modulated radiotherapy (IMRT) for low-risk invasive breast cancer patients is safe without causing serious late radiation side-effects.

The main purpose of this study is to confirm the high pathologic complete response rate after neoadjuvant chemotherapy with FEC followed by weekly paclitaxel and concurrent trastuzumab in Human Epidermal growth factor receptor2 (HER2) positive non operable breast cancer

This randomized, double-blind, placebo-controlled, two-arm study will assess the safety and efficacy of pertuzumab in addition to chemotherapy plus trastuzumab as adjuvant therapy in participants with operable HER2-positive primary breast cancer. This study will be carried out in collaboration with the Breast International Group (BIG).
