NCT07100106
The purpose of this study is to assess the safety of GDC-4198 alone and in combination with giredestrant and also the efficacy of GDC-4198 + giredestrant versus abemaciclib + giredestrant in participants with locally advanced or metastatic ER+, HER2- breast cancer. The study consists of 2 phases: Phase Ib and Phase II. Phase Ib will evaluate the safety and pharmacokinetics (PK) of GDC-4198 alone and in combination with giredestrant. Phase II stage will compare the activity and safety of GDC-4198 and giredestrant with abemaciclib and giredestrant.
NCT07459673
Thie purpose of this study is to find out whether a personalized treatment approach-using a series of ctDNA tests along with standard imaging scans to help decide when to step up (escalate) or decrease (de-escalate) sequential treatments (given one after another)-combined with local therapies (which treat cancer in a specific part of the body) and treatments that prevent cancer from spreading to the central nervous system (CNS; including the brain and spinal cord) can result in long-lasting remission and possibly cure some participants with HER2+ metastatic breast cancer.
NCT07465172
GRADE is trying to find out if there is a link between a hormone called GDF-15 and the side effects that people can experience when taking T-DXd. GDF-15 can be measured in the blood. GDF-15 levels in the blood will go up when the body is stressed under certain conditions, including breast cancer. There is a link between high GDF-15 levels and the nausea and vomiting experienced with "morning sickness" in pregnancy. It has also been shown that GDF-15 levels will go up with the use of other types of chemotherapy that are known to cause nausea and vomiting. Side effects such as feeling sick (nausea), vomiting and weight loss are common with T-DXd. Sometimes, these can be so severe that treatment needs to be stopped early. The investigators can't predict who will get bad side effects and who will not. If the investigators can find out if there is a link between GDF-15 and the side effects of T-DXd, they can use this information in future clinical trials.
NCT07219277
Breast cancer is the most common cancer that spreads beyond the initial layer of tissue it developed in, and grows into surrounding healthy tissue in women worldwide. It is associated with significant illness and death. Identifying the disease in the early stage is important to achieving positive outcomes in response to diagnosis and treatment. The Syantra blood test has been developed over the past 10 years. This test involves examining blood samples to identify and analyze specific information. This information is run through a software program that then potentially identifies the presence of breast cancer in the blood sample. This test has the potential to increase early stage detection of breast cancer. The main goal of this study is to figure out how well the Syantra blood test identifies the presence of breast cancer in women 30-75 years of age. The study will also look at whether things like ethnicity, geography and certain individual characteristics (including breast density and elevated risk of breast cancer development) have an effect on how well the test works. This study will recruit women who are attending a visit at the site who are aged 30-75 who are undergoing testing for the presence of breast cancer as part of their regular screening or planned follow up imaging and/or biopsy. Participants who provide consent and meet eligibility criteria will complete a baseline questionnaire and have their blood drawn before any scheduled procedures. Relevant information will be collected from their medical record at the time of joining the study and will be reviewed and updated within 60 days and then again at 12 months following the baseline blood draw. Participants will not have to do anything after the initial visit where they may sign consent, complete the intake questionnaire and have their blood drawn.
NCT07274709

NCT02290834
This research study evaluates the effect of chemotherapy on cognition (thinking) and the brain in people with breast cancer.
NCT07447440
The main objective of this project is to determine the possible association between the levels of certain bioactive lipids, which the body produces from dietary fatty acids, and tumor characteristics in breast cancer patients, as well as their relationship with overweight/obesity. Specific objectives are: * To analyse anthropometric and body composition changes. * To evaluate physical activity level. * To determine dietary profile. * To determine the adherence to Mediterranean dietary pattern. * To assess the quality of life. * To determine levels of specialized pro-resolving lipid mediators The target sample size is 60 subjects. Participants will be allocated in four groups: * Group 1: Postmenopausal healthy women with overweight/obesity (n=15) * Group 2: Postmenopausal healthy women with normoweight (n=15) * Group 3: Postmenopausal women with breast cancer and overweight/obesity (n=15) * Group 4: Postmenopausal women with breast cancer and normoweight (n=15)
NCT07455955
The objectives of this study are to determine if pharmacogenetic (PG) analysis of an individual enable optimal selection of antiemetic regimen for patients undergoing the first cycle of AC (Adriamycin + Cyclophosphamide) or FEC (Fluorouracil + Epirubicin + Cyclophosphamide) chemotherapy. It also aims to compare the quality of life of patients in the first cycle of AC / FEC chemotherapy with and without PG analysis. Patients will be randomized to undergo PG analysis \[PG group\] versus no PG analysis \[Non-/+PG group\]. Those in the PG group would be offered currently available optimal antiemetic prophylaxis, with or without Olanzapine according to PG outcomes. Those in the Non-PG group would be offered currently available optimal antiemetic prophylaxis.
NCT01266642
This randomized phase II trial studies how well hypofractionated radiation therapy (RT) works compared to standard RT in treating patients with ductal breast carcinoma in situ (DCIS) or early invasive breast cancer. Radiation therapy (RT) uses high energy x-rays to kill tumor cells. Giving higher doses of RT over a shorter period of time may kill more tumor cells and have fewer side effects. It is not yet known if hypofractionated RT is more effective than standard RT in treating breast cancer.
NCT03006172
This is an open-label, multicenter, Phase I study designed to evaluate the safety, tolerability, and pharmacokinetics of inavolisib administered orally as a single agent in patients with locally advanced or metastatic PIK3CA-mutant solid tumors, including breast cancer, and in combination with standard-of-care endocrine and/or targeted therapies for the treatment of locally advanced or metastatic PIK3CA-mutant breast cancer. Participants will be enrolled in two stages: a dose-escalation stage (Stage I) and an expansion stage (Stage II). Participants will be assigned to one of seven regimens: inavolisib as a single agent (Arm A), inavolisib in combination with palbociclib and letrozole (Arm B), inavolisib in combination with letrozole (Arm C), inavolisib in combination with fulvestrant (Arm D), inavolisib in combination with palbociclib and fulvestrant (Arm E), inavolisib in combination with palbociclib, fulvestrant, and metformin (Arm F), and inavolisib in combination with trastuzumab and pertuzumab (and letrozole or fulvestrant, if applicable (Arm G)).
NCT06982313
Low-dose tamoxifen (5 mg/day for three years, BabyTam) has emerged as a safer and effective alternative to the standard regimen (20 mg/day), reducing breast cancer recurrence with fewer adverse events. The TAM-01 phase III trial demonstrated a 42% reduction in breast cancer events over ten years compared to placebo in women with ductal carcinoma in situ (DCIS) or high-risk lesions (HRL, ADH, LCIS), supporting its inclusion in clinical guidelines. The phase III TAM-01 trial enrolled 500 women, comparing low-dose tamoxifen to placebo over three years, with a median follow-up of 9.7 years (IQR, 8.3-10.9). Results showed a significant reduction in invasive breast cancer (HR = 0.58; 95% CI: 0.35-0.95; p = 0.03) and in contralateral breast cancer, CBC (HR = 0.36; 95% CI: 0.14-0.92; p = 0.025), with no increase in serious adverse events. Exploratory analyses suggested a greater benefit in postmenopausal women (HR = 0.30; 95% CI: 0.11-0.82), compared to premenopausal women (HR = 0.73; 95% CI: 0.30-1.76), though this interaction did not reach statistical significance (p-interaction = 0.13). However, our unpublished data indicate a remarkable reduction of CBC in premenopausal women on BabyTam. The TAM-01 long-term follow-up study aims to extend the follow-up of TAM-01 participants, evaluating long-term outcomes, including incidence of invasive breast cancer and DCIS, with a focus on tumor laterality and menopausal status, as well as to assess other non-invasive events (LCIS, ADH, or ALH) and adverse outcomes of special interest. We will also perform a pooled analysis of our three low-dose tamoxifen studies to increase the statistical power of our findings, with special attention to the effect according to menopausal status and site of recurrence. The primary endpoint will be the breast cancer-free interval. The findings are expected to strengthen the evidence supporting low-dose tamoxifen as a viable prevention strategy in high-risk populations with intraepithelial neoplasia (IEN or DCIS+HRLs) or microinvasive disease.
NCT04454528
The primary objective is to determine the feasibility of combining pembrolizumab with a single fraction radiation boost in patients with early/ operable breast cancer. The secondary objectives are to assess clinical response on pre- and post-treatment clinical, imaging, and histology exams, and to assess immune response on pre and post treatment blood and tissue samples by tracking change in Ki67 + CD8 T cells in peripheral blood and in extent of tumor infiltrating lymphocytes. A clinically significant partial response is defined as \>30% tumor shrinkage post-clinical trial intervention.
NCT06954623
Breast cancer is the most common malignancy in women. Breast-conserving surgery (BCS) with adjuvant whole-breast irradiation (WBI) is currently the standard of care in the oncological treatment of primary breast cancer and offers an equivalent alternative to mastectomy. The primary aim of adjuvant radiotherapy (RT) is to improve local control and thus improve overall survival and breast cancer-specific mortality. However, nodal-negative women have a 10-year risk for local recurrences after RT in up to 15.6%. The management of ipsilateral breast cancer recurrence depends on the extent of tumor disease and staging results at the time of recurrence and mastectomy is currently the standard of care for previously irradiated patients. The application of particle therapy using proton beam therapy (PBT) represents an innovative radiotherapeutic technique for breast cancer patients. This trial will be conducted as a prospective single-arm phase II study in 20 patients with histologically proven invasive breast cancer recurrences with negative margins after repeat BCS and with an indication for local re-irradiation. Required time interval will be 1 year after previous RT to the ipsilateral breast. Patients will receive partial breast re-RT with proton beam therapy in 15 once daily fractions up to a total dose of 40.05 GyRBE. The primary endpoint is defined as the cumulative overall occurrence of acute / subacute skin toxicity grade ≥3 within 6 months after the start of re-RT.
NCT03619083
This study is being done to find out if a new series of evaluations called the SAE (Sensory-Attention-Executive) Battery can help researchers learn more about how cancer treatment does or does not change the way the brain processes/filters information, emotions, attention span, and behavior by comparing the results of the SAE Battery with traditional evaluations like questionnaires.
NCT02779855
The purpose of this study is to determine if an oncolytic virus called Talimogene laherparepvec (a modified herpes simplex 1 virus that can specifically destroy cancer cells while leaving normal cells alone) injected directly into the tumor during chemotherapy prior to surgery can enhance the elimination of triple negative breast cancer tumors. The natural herpes simplex 1 virus typically causes cold sores around the mouth, but the talimogene laherparepvec version of the herpes virus has been changed to prevent it from reproducing in normal tissue. However, it can still attack and break open cancer tissue which is why it is used as a treatment for cancer. It is thought that this virus can also help recruit the participant's immune system to attack the cancer cells during their treatment and possibly destroy the tumor tissue more effectively than chemotherapy alone. This virus is already FDA approved to treat melanoma skin tumors, so investigators want to determine if this virus can achieve a similar benefit in women with triple negative breast tumors.

NCT03838419
Breast cancer is the most frequent malignancy in women. Standard therapy for early-stage breast cancer is breast conserving surgery (BCS) followed by adjuvant whole breast irradiation (WBI), which usually requires a treatment time of 3-6 weeks. Several randomized controlled trials (RCTs) demonstrated that postoperative WBI after BCS significantly decreased the risk of local (in-breast) recurrence and improved breast cancer mortality as well as survival. However, one of the most common side-effects of radiotherapy is fatigue, which is reported in up to 80% of cancer patients during treatment. Especially in early-stage breast cancer patients it might be the only serious side-effect following adjuvant irradiation, as fatigue often significantly reduces quality of life due to resulting functional impairment and psychological distress. Fatigue additionally has a distinct socioeconomic impact: 75% of patients and 40% of caregivers are forced to change their employment status due to cancer-related fatigue. For reducing treatment-related toxicity, several RCTs consequently addressed the question whether adjuvant WBI could be omitted in early-stage, low risk breast cancer patients treated with endocrine therapy. However, all these trials detected up to seven-time increased local recurrence rates without WBI following BCS. Both, longer duration of radiotherapy and larger radiation field sizes are known to be associated with increase in treatment-related fatigue. Accelerated partial breast irradiation (APBI), delivered exclusively to the original tumor location and not to the surrounding breast tissue, might therefore be an alternative treatment option with fewer side-effects for early-stage, low risk breast cancer patients. Few previous trials have already reported comparable outcomes for highly selected low-risk breast cancer patients for APBI compared to conventional WBI. First results also point out that APBI compared to WBI might be associated with less severity and intensity of fatigue. One method for APBI is single-dose intraoperative radiotherapy (IORT) delivered directly to the tumor after resection. Data is still limited for APBI, hence current international and German guidelines suggest the use of APBI for low-risk early stage breast cancer patients but recommend the application of APBI preferably within a clinical trial.
NCT00367666
This project is aimed at investigating the relative diagnostic and synergy of four state of the art breast imaging techniques (magnetic resonance imaging (MRI), full-field digital mammography (DMAM), ultrasound, and positron emission tomography (PET)) with respect to determining the extent of breast cancer.
