Active clinical trials for "Breast Neoplasms"

Our study is aimed to explore a prospective observational clinical study on the efficacy prediction and survival prediction of HR + / HER2 - biomarkers detection in patients with advanced breast cancer. This study is a prospective, observational clinical study. We analyzed the incidence of biomarker mutations in HR + / HER2 - advanced breast cancer (stage IV), and the correlation between biomarkers and therapeutic efficacy, survival, and prognosis.

This study is a Non-Interventional Study (NIS) with secondary data usage. It is designed as a multi-center retrospective cohort study in which the data of adult locally advanced HER2-positive breast cancer patients, who are treated with as neoadjuvant therapy, who underwent breast surgery in participating centers, were taken from hospital records. The source population is academic or community oncology centers treating patients with breast cancer from Turkey. The study population is planned to be the subgroup of breast cancer patients, who are treated with trastuzumab plus taxane with or without pertuzumab as neoadjuvant therapy, and underwent breast surgery at the participating centers. The study is anticipated to include approximately 1500 patients from 20 sites.

Currently there are five trastuzumab biosimilars approved by EMA (Ogivri® Mylan , Herzuma® Biogaran, Ontruzant® MSD, Trazimera® Pfizer, and Kanjinti® Amgen) for the treatment of HER2-positive breast cancer. EMA's approvals were obtained on phase I pharmacokinetic equivalence trials and phase III clinical trials based on efficacy primary endpoints in the neoadjuvant setting and on Overall Response Rate in metastatic setting. Safety was a secondary endpoints in these trials. Phase III pivotal trials compared trastuzumab biosimilars to Herceptin® in combination with chemotherapy in the neoadjuvant setting and in the metastatic setting. The trials were designed before the approval of pertuzumab (in the neoadjuvant and metastatic settings). Thus, there is no available prospective data on the safety and efficacy of trastuzumab biosimilars in combination with pertuzumab. A biosimilar compound can obtain an extrapolation of its indications to those of the reference biological product since bio-similarity has been demonstrated (ie pharmacokinetic equivalence and clinical studies in the most "sensitive" indications). To date, the use of trastuzumab biosimilar in combination with pertuzumab is allowed, but this combination is not supported by neither scientific evidence nor clinical guidelines. PETRA aims at evaluate the efficacy and safety of the combination of pertuzumab and a trastuzumab biosimilar in real life.

To explore the real world data of trastuzumab Combined With Trastuzumab And Chemotherapy in China, and to explore the relationship between progression free survival and treatment pattern.

Improving the early diagnosis of breast cancer can reduce mortality. With mammography as the main tool for screening early breast cancer, the characteristics of dense breast and young onset of disease in Chinese women lowers the efficiency. The aim of this prospective study was to compare which method, x-ray or ultrasound, is more appropriate for screening and early diagnosis of breast cancer in Chinese women.

Some cancer patients report experiencing mild problems with thinking during or following chemotherapy. Symptoms include problems concentrating, slow thinking, some gaps in memory and difficulty performing complex or multi-tasks. These symptoms often soon disappear after treatment. However for some patients, they may persist for years and this can have a significant effect on their quality of life. The reasons for these symptoms are not well understood. This study proposes to examine the effects of chemotherapy on the brain and how the changes in the brain affect one's ability to move one's arms and fingers. By better understanding the negative consequences of chemotherapy on the brain and nervous system, the hope is to help pharmaceutical companies develop safer cancer treatment drugs.

A prospective, non-interventional, non-controlled multicenter observational study to evaluate aspects of pharmaceutical care and the treatment of postmenopausal patients with hormone-receptor positive, HER2-receptor negative, advanced breast cancer treated with everolimus and exemestane. The main objective of the study is to evaluate medication adherence in postmenopausal, hormone-receptor positive, HER2-receptor negative, advanced breast cancer treated with a combination of everolimus and exemestane. Additionally, other aspects of the pharmacotherapy, with focus on the patient perspective, will be investigated: Patient satisfaction with treatment information Patient satisfaction with treatment Health-related quality of life Treatment efficacy Treatment-related toxicity Patient follow-up by the oncologic team/general practitioner and or specialized home nurses This study should reveal information necessary for the development of pharmacotherapeutic care concepts that meet the needs of cancer patients treated with an oral anti-cancer drug over a long period.

The TR(ACE) Assay is a quantitative in vitro diagnostic test run on the TR(ACE) Instrument intended for the measurement of high molecular weight human DNA from plasma as an aid to monitoring disease progression or response to therapy or recurrent or residual disease.

Breast cancer has become a major public health problem in Latin America, as it is the most common form of cancer among women. Women are more likely to develop breast cancer at younger age, and to be diagnosed at an advanced stage compared to western women. Over the past twenty years, the mortality from breast cancer in Latin America has also been increasing very rapidly, and is currently the leading cause of cancer mortality. Little is known on specific risk factors for premenopausal breast cancer in general, and in Latin America in particular. There is a lack of specific knowledge on tumor molecular and pathological characteristics of breast cancer in Latin America premenopausal women, and this has major consequences on cancer treatment and survival. To improve our understanding on determinants of breast cancer incidence and mortality in young Latin America women and support preventive actions, we implemented an international, population-based multi-center study in Latin America: the PRECAMA study (Molecular Subtypes of Premenopausal Breast Cancer in Latin American Women (PRECAMA): a multicenter population-based case-control study). PRECAMA is coordinated by the International Agency for Research on Cancer (IARC), and is conducted within 4 Latin American countries: Mexico, Costa Rica, Colombia and Chile. Major aims of the project are the following: To develop a multi-centric population-based case-control study on breast cancer in premenopausal women in several countries in Latin America with structured collection of individual, clinical, pathological information and biological specimens, according to strictly controlled protocols To characterize, in these populations, the subtypes of premenopausal breast cancer on the basis of their molecular and pathological phenotypes To improve the identification of specific endogenous/exogenous factors, and disentangle the interplay of these different factors with regard to breast tumor subtypes. Provide advanced training, induce a structuring effect on the breast cancer research community in Latin America and influence the public health agenda regarding the management of breast cancer. The results of our study will be of utmost importance to understand the etiology of breast cancer in Latin America countries, and would provide important information on the role of modifiable exposures for breast cancer prevention.

This is a pilot prospective cohort study, in adult female subjects 18-85 years old with a diagnosis of invasive breast cancer who are planned for anthracycline-inclusive chemotherapy and followed up for a time period of 6 months post completion of anthracycline chemotherapy. They will participate in blood and imaging tests with a goal of determining the best method for predicting the occurrence of cardiotoxicity in this subpopulation.
