To explore the genetic background of patients with HER2 positive breast cancer that benefit from trastuzumab combined with neoadjuvant chemotherapy, identify clinically actionable mutations that associated with trastuzumab resistance or drug efficacy, we designed this Observational phase II trial. The primary endpoint is genetic profile of HER2+ breast cancer patients treated with trastuzumab combined neoadjuvant chemotherapy. Secondary endpoints included pathological complete response (pCR) rate and safety.
Accurate staging is of great importance in patients with clinically locally advanced primary breast cancer (LABC, stage III) or locoregional recurrent (LRR) breast cancer for making a correct treatment plan. According to current guidelines, staging is performed with positron emission tomography (PET) using the 2-[18F]fluoro-2-deoxy-D-glucose ([18F]FDG) PET tracer, combined with diagnostic computed tomography (CT). However, previous studies have shown that this technique (with the current PET tracer) might not be sufficient for accurate staging. Specifically in low grade, estrogen receptor positive (ER+) breast cancer metastases can be missed due to the low metabolic activity, leading to low uptake of [18F]FDG. Therefore, there is a clinical need to improve staging procedures. 16α-[18F]-fluoro-17β-estradiol ([18F]FES), an ER-targeted PET tracer, allows imaging of ER+ tumor lesions regardless of their metabolic activity. Patients with clinically LABC and LRR have a 25-50% risk of distant metastases. Correct identification of distant metastases allows adaptation of the treatment plan to avoid burdensome treatment with surgery, systemic and radiotherapy in order to maintain quality of life. In case of oligometastases, correct identification increases the likelihood for cure with local treatment. In the current study we will compare disease staging with [18F]FES- and [18F]FDG PET in patients with clinically LABC/LRR breast cancer. Objective: To determine whether [18F]FES PET/CT improves staging for women with clinically LABC or LRR, ER+/HER2- breast cancer as compared to standard [18F]FDG PET/CT. Study design: Multicenter prospective study with invasive measurements. Study population: 20 LABC and 20 LRR ER+/HER2- breast cancer patients. Main study parameters/endpoints: To determine the percentage of patients with a correctly changed treatment plan according to information obtained from [18F]FES PET/CT compared to [18F]FDG PET/CT at staging and at 6 months of follow-up; to determine the percentage of metastatic lesions detected and missed with [18F]FES PET/CT compared to [18F]FDG PET/CT (at staging and during follow-up). Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Patients will receive an intravenous cannula for tracer injection and blood sampling, causing potentially transient discomfort at the site of the cannula insertion. Tumor biopsy will be performed from an easy accessible lesion and the most frequent complications that can occur are discomfort, bleeding and (local) infection. The risk of complications from a tumor biopsy is considered low: 0.24-1.6% and 0.11-0.48% for major complications and mortality, respectively. Radiation exposure from a [18F]FES PET and [18F]FDG PET scan usually ranges between 4-11 mSv and 7-8 mSv, respectively. Radiation exposure from a diagnostic CT scan ranges between 8-14 mSv. The total radiation burden is considered justifiable when compared to the information that can be obtained from this study, in this patient group with breast cancer. Imaging with [18F]FES PET may improve staging for patients with breast cancer as it may show tumor lesions that could not be identified with [18F]FDG PET, the current standard for staging. If this is the case, the initial treatment goal and intensity can be adjusted which can have beneficial effects for the patient.
This study (also known as IMpassion050) will evaluate the efficacy and safety of atezolizumab compared with placebo when given in combination with neoadjuvant dose-dense anthracycline (doxorubicin) + cyclophosphamide followed by paclitaxel + trastuzumab + pertuzumab (ddAC-PacHP) in patients with early HER2-positive breast cancer (T2-4, N1-3, M0).
This phase Ib trial studies the side effects and best dose of ALRN-6924 when given together with paclitaxel in treating patients with solid tumors that have spread to other places in the body or cannot be removed by surgery. Drugs used in chemotherapy, such as ALRN-6924 and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading.
The purpose of this study is to assess the efficacy and safety of pembrolizumab (MK-3475) versus placebo in combination with neoadjuvant (pre-surgery) chemotherapy and adjuvant (post-surgery) endocrine therapy in the treatment of adults who have high-risk early-stage estrogen receptor-positive, human epidermal growth factor receptor 2-negative (ER+/HER2-) breast cancer. The primary study hypotheses are: 1) pembrolizumab is superior to placebo, both in combination with the protocol-specified neoadjuvant anticancer therapy, as assessed by pathological Complete Response (pCR) rate defined by the local pathologist, and 2) pembrolizumab is superior to placebo (both in combination with the protocol-specified neoadjuvant and adjuvant anticancer therapies) as assessed by Event-Free Survival (EFS) as determined by the investigator. The study is considered to have met its primary objective if pembrolizumab is superior to placebo with respect to either pCR (ypT0/Tis ypN0) or EFS.
This randomized research trial studies how well serum tumor marker directed disease monitoring works in monitoring patients with hormone receptor positive Her2 negative breast cancer that has spread to other places in the body. Using markers to prompt when scans should be ordered may be as good as the usual approach to monitoring disease.
This trial studies how well occupational therapy (occupational therapist-led work intervention) works in facilitating work maintenance or re-entry to the workforce for stages I to III breast cancer patients who will be undergoing curative intent chemotherapy. Occupational therapy may help cancer patients maintain employment or successfully return to work soon after treatment.
This research study is studying a PET imaging tracer as a possible means of imaging breast cancer. The imaging agent involved in this study is: -[11C]Martinostat (called C-eleven-Martinostat)
This is a phase 1b, open-Label clinical trial to determine the safety and tolerability and to establish a preliminary recommended Phase 2 dose (RP2D) of TTAC-0001 administered in combination with pembrolizumab in patients with metastatic triple-negative breast cancer.
