Active clinical trials for "Breast Neoplasms"

Randomized Controlled Trial of Neoadjuvant Progesterone and Vitamin D3 in women with Large Operable Breast Cancer and Locally Advanced Breast Cancer - A Feasibility Study Primary Progesterone Timing of surgery during the menstrual cycle and its impact on survival in premenopausal women with operable breast cancer has been extensively researched and reinvestigated by Badwe et al in the randomized clinical trial of 'Primary Progesterone Therapy for Operable Breast Cancer' at Tata Memorial Hospital. The underlying assumption was that the presence of unopposed estrogen (in follicular phase) at the time surgery may be deleterious for survival and that circulating progesterone might counteract this deleterious effect. Vitamin D3 The most prominent physiological role of hormonally active form of vitamin D3, 1,25-dihydroxyvitamin D3 (1,25(OH)2D3 or calcitriol), is regulation of calcium and phosphorous homeostasis and bone metabolism via an intracellular receptor (VDR) which is a member of steroid thyroid hormone super-family of receptors. The VDR receptors are also found in other tissues like breast and prostate. Vitamin D compounds have also been implicated in promotion of apoptosis in breast cancer cells and evidence suggests that 1,25(OH)2D3 and its synthetic analogues may potentiate responsiveness of breast cancer cells to conventional cytotoxic agents. Objectives To see the effect of primary progesterone on survival in women with high risk breast cancer (large operable and locally advanced breast cancer) To see the effect of Vitamin D3 as an antiproliferative, cytotoxic and apoptotic agent (negative growth regulator) by evaluation of surrogate markers of proliferation and apoptosis. Inclusion Criteria: Unilateral breast cancer Large operable breast cancer/LOBC (T3N0M0 or T3N1M0) and Locally advanced breast cancer/LABC (T3N1-2M0; T2N2M0) Age <70 years Fit for CT Exclusion Criteria: Prior Incision Biopsy or Excision Biopsy Metastatic breast cancer Renal failure or deranged Renal Function Test Hypoparathyroidism Pregnant or lactating mothers or women of childbearing age not practicing contraception Patient on any of the following drugs: Magnesium-containing antacids, Digitalis, Phenytoin barbiturates, Thiazide diuretics. Previous history of other cancers except cured skin and cervical carcinoma in situ. Methodology / Treatment plan The study drugs (Injectable Progesterone and Vitamin D3) will be tested in the neoadjuvant setting prior to administration of each chemotherapy cycle, in a 2x2 factorial design as below: Neoadjuvant D3 will be administered as Inj. Arachitol 300,000 IU/ml intramuscular, before each chemotherapy cycle. Neoadjuvant Progesterone used will be administered as single IM depot injection 500mg 5 days prior to each CT cycle and surgery date. Primary Objectives Disease-free survival Secondary Objectives Improvements in overall survival Tumor response

This single arm. open-label study will assess the efficacy and safety of Herceptin (trastuzumab) in combination with Xeloda (capecitabine) in patients with metastatic or recurrent HER2-positive breast cancer, refractory to or relapsing after chemotherapy with Herceptin and taxanes. Patients will receive Xeloda 900mg/m2 twice daily orally on days 1-14 of each 3-week cycle and Herceptin 8mg/kg intravenously (iv) on day 1 of the first cycle followed by 6mg/kg iv every 3 weeks. The anticipated time on study treatment is until disease progression or unacceptable toxicity occurs.

This phase II trial studies the impact of a presurgical endocrine therapy, consisting of goserelin with letrozole or anastrozole on the treatment of premenopausal patients with stage II-III estrogen receptor-positive (ER+) and human epidermal growth factor receptor 2 (HER2)-negative breast cancer. Endocrine therapy reduces the amount of estrogen in the body. E+ breast cancer require estrogen, so lower levels of estrogen may slow or stop cell growth. Giving goserelin together with letrozole or anastrozole before surgery may enhance the effectiveness of, or eliminate the need for, chemotherapy

The humanized monoclonal antibody against Lewis Y antigen (Hu3S193) has been demonstrated to be safe in previous studies and has also been indicated as potential intervention in breast cancer. The study of this new agent in advanced breast cancer may contribute to the development of new strategies for patients that progressed after hormonal treatment.

This study is investigating the effects of a new hormone treatment for breast cancer called Irosustat. Seventy percent of breast cancers in post-menopausal wome rely on oestrogen to grow therefore are likely to respond to hormone therapy. Irosustat blocks a different pathway of steroid synthesis to Aromatase, reducing in this way oestrogen levels in the body. As less oestrogen reaches the breast cancer, it grows more slowly or stops growing altogether. IPET will recruit postmenopausal women with early, hormone sensitive, treatment naive breast cancer will receive 40mg of Irosustat once daily for 2 weeks. The effects of Irosustat on breast cancer will be evaluated by PET scans (Positron Emission Tomography) using a radioactive substance called FLT as a tracer. The scans will be performed in a PET-CT scanner which combines a PET scan and a CT scan (Computer Tomography) into one scan. This type of scan can show how body tissues are working, as well as what they look like. FLT-PET scans will be performed before and following treatment with Irosustat. As cancer cells grow faster than the normal cells around them, they will take up more of the radioactive substance, and so stand out clearly on the scan. If Irosustat is slowing down the cancer growth, the cancer will take up less of the tracer. Blood samples will be taken at regular intervals to assess what the new drug does to the body and the safety and tolerability of Irosustat will be assessed. The study incorporates translation aspects/endpoints which are based on the collection of tumour biopsies before and after treatment with Irosustat although the later biopsy is not mandatory.

This phase I/II trial studies the side effects and the best dose of triciribine phosphate when given together with paclitaxel, doxorubicin hydrochloride, and cyclophosphamide and to see how well they work in treating patients with stage IIB-IV breast cancer. Triciribine phosphate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as paclitaxel, doxorubicin hydrochloride, and cyclophosphamide, 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. Giving triciribine phosphate with paclitaxel, doxorubicin hydrochloride, and cyclophosphamide may be a better treatment for breast cancer.

This Phase Ib/II study is an openlabel, multicenter study for patients with solid tumors and breast cancer amenable to anthracyclin therapy. The study is divided in two parts: Phase I: an open-label, dose escalation study of F16IL2 in combination with doxorubicin for patients with solid tumors. Phase II: a prospective, single-arm, multicentre study of a fixed dose of F16IL2 in combination with doxorubicin, equivalent to stage 1 of the Simon two-stage phase II design, for patients with breast cancer amenable to anthracyclin therapy.

The primary objective of this study is to identify the group of women with early stage breast cancer most likely to benefit from treatment with the selective progesterone receptor modulator (SPRM) mifepristone. This will be done by treating women briefly prior to planned surgery and examining the decrease in growth rate (measured by Ki-67 immunohistochemistry) in tumor samples taken before and after exposure to mifepristone.

PF-04691502 is an inhibitor of PI3K and mTOR kinase. Published data support the hypothesis that a PI3K/mTOR antagonist in combination with letrozole might mitigate the intrinsic or acquired resistance to hormonal therapy and restore hormone sensitivity in high risk (high Ki-67) patient population of hormone-sensitive breast cancers. In addition, Ki-67, a marker of cellular proliferation, could be used to select those patients who benefit from treatment with a PI3K-pathway inhibitor.

Participants in this study will have been diagnosed with advanced breast cancer that has become worse while being treated with fulvestrant. Participants will have estrogen-receptor positive disease, and have completed menopause. There is information from research labs which suggests that drugs that work like MLN9708 help kill breast cancer cells that have been treated with fulvestrant. The purpose of the study is to determine the proper dose as well as the good and bad effects of MLN9708 when it is given in combination with fulvestrant. The Investigators also want to learn more about how the drug combination affects tumor cells. The amount of MLN9708 participants receive will be determined by when they enter this study. Three different doses will be given to different participants. The Investigators expect to enroll a total of 12-18 people.
