NCT ID: NCT03794596 Not yet recruiting - Breast Cancer Clinical Trials

A Proof of Concept, Window Trial of the IMmunological Effects of AveLumab and Aspirin in Triple-Negative Breast Cancer

Start date: May 2019
Phase: Phase 2
Study type: Interventional

This research is being done because the investigators are looking for new and better ways to treat a type of breast cancer called triple negative breast cancer. This type of breast cancer can be more difficult to treat than other types of breast cancer as it does not respond to drugs such as hormonal therapies. One type of treatment that looks promising is immunotherapy using new drugs called immune checkpoint inhibitors. Immune checkpoints help to regulate the immune system and can stop the immune system from attacking cancer cells. Immune checkpoint inhibitors block this 'off-switch' and aim to help the immune system control the cancer. These drugs have been very effective in other cancers such as melanoma and are now being tested in breast cancer. In this study patients will receive an immune checkpoint inhibitor called avelumab. Half the patients on the study will also receive aspirin tablets for approximately 18 days as the investigators wish to compare the effects of avelumab alone versus in combination with aspirin. Patients will attend hospital approximately five times in order to complete all necessary study assessments. The first visit screens patients for suitability, after which a baseline visit will collect the first of two breast tissue biopsies. At the third visit a single dose of Avelumab will be given via an infusion (a drip in the forearm). Patients will then return approximately two weeks later for a second breast tissue biopsy before having a final follow up visit another two weeks later. Blood and urine samples will be taken at various visits throughout the study to help us learn more about the effects these treatments may have on the immune system and on breast cancer cells.

Prognosis and Targeted Therapy Related Molecular Screening Program for Patients of Breast Cancer in China

Start date: July 20, 2017
Study type: Observational

The anticipated objectives of this study are: 1) to understand the pathogenesis and molecular typing of breast cancer patients in China (mainly HER2 overexpression, triple negative and hormone receptor-positive patients) by detecting DNA and RNA in tumor tissue (fresh tissue or paraffin section), and to compare the similarities and differences between the western population and Chinese population; 2) plasma samples of patients with HER2 overexpression , hormone receptor-positive and triple negative (ER, PR, HER2 expression negative) were sequenced for ctDNA and ctRNA, to find out whether there are genes or gene sets related to therapeutic effect; 3) to study the specific changes of liquid molecular detection results according to the previous research results, and establish mathematical models to predict and monitor the effects of targeted therapy and endocrine therapy; 4) to compare liquid biopsy and imaging and clinical features in monitoring clinical therapeutic effect, and to elaborate the advantages and disadvantages of liquid biopsy and conventional imaging; 5) to provide molecular detection basis for follow-up clinical research and screening for targets of new drugs.

NCT ID: NCT03791736 Terminated - Breast Cancer Clinical Trials

Evaluation of Impact of Sandostatin® Injection Before Axillary Clearance on Lymphocele Formation

Start date: July 6, 2016
Phase: N/A
Study type: Interventional

The lymphocele is the main early postoperative complication of axillary clearance for breast cancer patients with rates up to 85%. The usual treatment consists of external drainage. However, this method increases the duration of hospitalization. As a result, some practitioners have abandoned drainage, allowing for ambulatory surgery. If this solution makes it possible to reduce the duration of the hospitalizations, it involves iterative punctures of the axillary hollow in case of lymphocele These punctures may be responsible for pain, hematoma or infection of the operative site. To date, no method has proved superior in terms of decreasing the incidence of lymphocele postoperatively axillary clearance. Octreotide (Sandostatin®) is a peptide, one of whose effects is to reduce the inflammation responsible for lymphoceles. The aim of the study is to inject Sandostatin® before surgery, with the aim of reducing the incidence of seroma by 50% after axillary clearance

Phase: N/A
Study type: Interventional

This study evaluates the impact of an online patient decision aid on the process of decision making regarding breast reconstruction and the decision quality in women with breast cancer undergoing mastectomy and considering immediate breast reconstruction. Half of participants will receive care as usual and access to the online decision aid, while the other half will receive care as usual including a standard information leaflet.

Assessment of Feasibility and Acceptability of Personalized Breast Cancer Screening

Start date: February 2019
Phase: N/A
Study type: Interventional

The overall objective is to assess the acceptability and feasibility of offering personalized breast cancer (BC) screening. The specific objectives are: 1) To design an information system; 2) To evaluate the barriers and facilitators of the coordination of health care services and the screening program; 3) To develop a proof of concept of personalized screening; and 4) To evaluate cost-effectiveness. Methodology: 1. Prototype information system with basal and longitudinal variables relevant to a personalized screening system; 2. Qualitative study with focus groups and survey. The attitude and acceptability on a sample of 210 health professionals will be assessed; 3. Prospective observational study, for proof of concept. Participants will be professionals working in Primary Care, Population Breast Screening Program, or Hospital Breast Unit. It will include 385 women, aged 40-50 from the city of Lleida. Various indicators of acceptability and feasibility will be assessed in women and health professionals; 4. Probabilistic analytical models will be used to evaluate cost-effectiveness. The present protocol addresses the specific objective number 3, the proof of concept of personalised screening. Expected results: The investigators expect to provide valuable and necessary information for the design of personalized screening.

18F-ASIS PET/CT Imaging of Tissue Factor Expression In Patients With Primary and Metastastic Cancer

Start date: January 3, 2019
Phase: Phase 1
Study type: Interventional

The primary objective of the trial is to test the new radio tracer 18F-ASIS for PET imaging of tissue factor (TF) expression. The tracer has the potential of identifying tumors with high levels of TF expression, which is expected to correlate with tumor aggression and prognosis. Furthermore, the tracer can potentially be used as companion imaging diagnostic agent for identifying patients eligible for TF directed therapies. This is a first-in-man study to test the radio tracer in cancer patients. Safety, biodistribution and dosimetry will be evaluated by repeated PET imaging (1 hour, 2 hours and 4 hours post-injection).

Minimally Invasive Biopsy Predicting Breast pCR After NAC for Breast Cancer

Start date: June 1, 2017
Phase: N/A
Study type: Interventional

Neoadjuvant chemotherapy (NAC) is widely used as an efficient breast cancer treatment. Ideally, a pathological complete remission (pCR) can be achieved. With improvements in molecular typing guided NAC and targeted therapies, there has been dramatic improvement in pCR rates, especially among triple-negative and human epidermal growth factor receptor 2 positive breast cancers. Rates of pCR in these groups of patients can reach 60% or higher. NAC has significantly promoted the loco-regional de-escalating treatment of breast cancer, and the need for breast surgery in NAC cases with pCR has been questioned, especially in patients undergoing breast-conserving surgery with whole breast radiotherapy. The main impediments for potential elimination of breast surgery have been the fact that conventional and functional breast imaging techniques are incapable of accurate prediction of residual disease. However, imaging-guided minimally invasive biopsy (MIB) techniques might have the potential to overcome this impediment. The investigators design and begin a prospective one-armed clinical study to explore the accuracy of MIB in predicting breast pCR after NAC.
