Filter by:This phase II trial studies how well radiation therapy before surgery works in treating patients with hormone receptor positive, HER2 negative breast cancer. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.
Background: Despite that up 90% of patients with early-stage breast cancer receives adjuvant treatment, there are still about 300 patients diagnosed with primary metastatic breast cancer (MBC) and about 1,200 patients who develop metastases after the primary treatment each year in Denmark. Aim: The investigators hypothesize that molecular evaluation with FDG-PET/CT and diffusion weighted MRI allows an earlier detection of failure to respond to potentially toxic drugs in patients receiving breast cancer directed treatments. The aims of our project are to address the following questions: - Does FDG-PET/CT allow an earlier detection of failure to respond to treatment for MBC than conventional CT? - Does FDG-PET/CT or MRI allow an earlier detection of failure to respond to treatment for bone metastatic disease than conventional CT? - Does the PET based criteria (PERCIST) have the potential to lead to changes in the treatment plans made from CT based criteria (RECIST)? - Does FDG-PET/CT give a more accurate diagnosis of MBC than conventional CT in terms of number and distribution of metastatic sites? Method: Part A - the accuracy study: The study population will comprise all women referred to Odense University Hospital with suspected metastatic breast cancer (MBC). The investigators expect to include 270 patients who will be examined with FDG-PET/CT. If bone metastases are detected, the patients will proceed to MRI. All patients with suspected metastases on FDG-PET/CT or MRI will have a biopsy from a suitable lesion Part B - the response evaluation study: The investigators expect to include 90 patients with biopsy-verified MBC. Patients will receive oncologic treatment according to national guidelines. Response to treatment will be evaluated by conventional CT criteria and compared to novel criteria according to FDG- PET/CT, and MRI. Test results will be blinded to each other, so that knowledge of other test results will be unknown for the reader of the CT, FDG-PET/CT or MRI, respectively Expected clinical impact: This project represents a truly multidisciplinary effort to improve the diagnosis, staging, and response evaluation of MBC. The investigators hope that patients will benefit in terms of being spared for ineffective toxic treatment due to earlier detection of failure to respond, and hence leading to earlier treatment transition. Patients are involved in the planning and conduct of the project.
This phase II trial studies how well hypofractionated radiation therapy works in treating patients with stage 0-IIB breast cancer. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects.
This research study is for patients with metastatic breast cancer. - Metastatic means that the cancer has spread beyond the breast. In addition, through genetic testing of the blood or tumor, an altered gene has been found that suggests the tumor may not be able to repair its genetic material (DNA) when it becomes damaged. - This aspect of the cancer may cause it to be more sensitive - that is, more effectively killed by certain types of drugs such as the study agent being evaluated in this trial, Olaparib. - Olaparib is a type of drug known as a PARP inhibitor. Some types of breast cancer and ovarian cancer share some basic features that make them sensitive to similar treatments. Information from those other research studies suggests that this drug may help to treat metastatic breast cancer. - This study will evaluate whether olaparib is effective in breast cancer patients whose tumor has a mutation in one of the other genes that function with BRCA1 and BRCA2 to repair damaged DNA .This mutation may have been inherited from a parent, or may have developed only in the tumor. - This study will also evaluate whether olaparib is effective in breast cancer patients whose tumor has a mutation in BRCA1 or BRCA2 that was acquired by the tumor, but not inherited.
This is a Phase 1 study which consists of 2 parts; Dose Escalation part and Expansion part. The dose escalation part is open-label, and evaluates safety, preliminary efficacy and PK of single-agent talazoparib in sequential cohorts of adult patients with advanced solid tumors who are resistant to standard therapy or for whom no standard therapy is available. In the dose escalation part, up to 18 (minimum 3) patients are expected to be enrolled depending on the observed DLTs. The expansion part is designed to assess the efficacy, safety and PK of single-agent talazoparib at RP2D determined in the dose escalation part in adult patients with locally advanced or metastatic breast cancer who have deleterious or suspected deleterious germline BRCA1 or BRCA2 mutations. In the expansion part, a minimum of 17 patients will be enrolled evaluable for the primary endpoint.
This study will evaluate the safety, pharmacokinetic (PK), pharmacodynamic (PD) activity, and preliminary anti-tumor activity of GDC-9545 as a single agent and in combination with palbociclib and/or luteinizing hormone-releasing hormone (LHRH) agonist in participants with advanced or metastatic estrogen receptor (ER)-positive (human epidermal growth factor receptor 2 [HER2]-negative) breast cancer.
This study is to assess the efficacy and safety of olaparib monotherapy versus olaparib in combination with an inhibitor of ATR (Ataxia-Telangiectasia Mutated (ATM) and Rad3-related protein kinase (Ceralasertib [AZD6738]) and olaparib monotherapy versus olaparib in combination with an inhibitor of WEE1 (adavosertib [AZD1775]) in second or third line setting in patients with Triple-negative breast cancer (TNBC) prospectively stratified by presence/absence of qualifying tumour mutation in genes involved in the homologous recombination repair (HRR) pathway. Treatment arms are olaparib monotherapy, olaparib+ Ceralasertib and olaparib+adavosertib. The study subject population will be divided into Stratum A, Stratum B, and Stratum C. Due to the different schedules of administration of each of the treatment options as well as their different toxicity profiles, the study is not blinded. Study has two stage consent process- stage 1 consent (molecular screening for HRR defects) and stage 2 consent (main study). Patients with TNBC and with known qualifying BRCAm, non BRCAm HRRm and non HRRm status will be offered the option of consenting to the main part of the study within the 28-day screening period. Following the ISRC meeting on 17 April 2019 a recommendation was made to close the adavosertib+olaparib treatment arm across all biomarker strata. Patients receiving treatment with adavosertib+olaparib treatment were offered the opportunity to continue treatment on olaparib monotherapy at the approved dose (300 mg bd). Following the closure of this arm the total number of patients randomised will be lower (approximately 350 patients). Approximately 300 patients will be randomised (using randomisation ratio 1:1) to 2 ongoing treatment arms plus an additional 47 patients to a 3rd arm (olaparib+adavosertib) prior to the arm being discontinued.
Multicenter open-label, phase II trial, to evaluate the efficacy and safety of nal-IRI in patients with HER2-negative breast cancer, who have documented Central Nervous System (CNS) progression following Whole Brain Radio Therapy (WBRT), Stereotactic Radiosurgery (SRS) and/or surgery, as determined by the Response Assessment in Neuro-Oncology Brain Metastases (RANO-BM) criteria.
This multicenter, randomized, comparative study will evaluate the efficacy of denosumab to prevent the adjuvant therapy of aromatase inhibitors-induced loss of bone mineral density (BMD) in breast cancer patients with normal BMD. Investigators will compare the inhibitory effects of denosumab on bone loss between participants with normal BMD to whom Letrozole or Arimidex will be administered as postoperative endocrine therapy for stage I-IIIA postmenopausal hormone-sensitive breast cancer and controls.
This study recruits patients with metastatic breast cancer who have progressed on their current regimen of dual anti-HER2 therapy. This study evaluates whether or not the addition of simvastatin to the dual anti-HER2 therapy regimen helps make the tumor respond to the anti-HER2 therapy again. All participants will receive simvastatin in combination with their current anti-HER2 therapy regimen.
