NCT00003857
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Estrogen can stimulate the growth of breast cancer cells. Hormone therapy using tamoxifen may fight breast cancer by blocking the uptake of estrogen by the tumor cells. It is not yet known if radiation therapy is more effective than observation, with or without tamoxifen, in treating ductal carcinoma in situ. PURPOSE: Randomized phase III trial to compare the effectiveness of radiation therapy with that of observation, with or without tamoxifen, in treating women who have ductal carcinoma in situ.
NCT04112095
This study is designed to assess whether consumers select and use norgestrel 0.075 mg, a progestin only pill for contraception, in a manner consistent with the OTC package directions in an Over-the-Counter (OTC)-like setting.
NCT02839343
This randomized phase II trial studies how well combination chemotherapy (mFOLFIRINOX) with or without hypofractionated radiation therapy before surgery works in patients with pancreatic cancer that can be removed by surgery. Drugs used in combination chemotherapy, such as oxaliplatin, leucovorin calcium, fluorouracil, and irinotecan hydrochloride, 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. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects. It is not yet known if combination chemotherapy is more effective with or without hypofractionated radiation therapy before surgery in treating patients with pancreatic cancer.
NCT02301156
This study evaluates the effect of the addition of ublituximab, a novel monoclonal antibody, to ibrutinib compared to ibrutinib alone on antitumor activity, as measured by the overall response rate (ORR = CR \[complete response\] + PR \[partial response\]) in previously treated Chronic Lymphocytic Leukemia (CLL) participants with high-risk cytogenetic features. Half of the participants will receive ublituximab in combination with ibrutinib, while the other half will receive ibrutinib alone.
NCT01369199

NCT02999854
The primary objective of this study is to compare safety and efficacy of a haploidentical T-cell depleted HSCT and adjunctive treatment with ATIR101 versus a haploidentical T cell replete HSCT with post-transplant administration of high dose cyclophosphamide (PTCy) in patients with a hematologic malignancy. An additional objective of the study is to compare the effect of the two treatments on quality of life.
NCT03548220
Study AG348-C-006 evaluated the efficacy and safety of orally administered AG-348 as compared with placebo in participants with pyruvate kinase (PK) deficiency, who were not regularly receiving blood transfusions. Participants were randomized 1:1 to receive either AG-348 or a matching placebo.
NCT02415556
The main purpose of this study is to find the long-term effects of daily administration of 40 IU of intranasal insulin (INI) as compared to placebo (sterile saline) on cognition and memory in people with type 2 diabetes mellitus (DM), and non-diabetic controls over 24 weeks with a follow-up period for 24 weeks. Four groups will be tested: DM group treated with INI; DM group treated with placebo; control group treated with INI and the control group treated with placebo. The INI or placebo will be delivered into the nose. The investigators are interested to see whether INI can improve memory and cognition and blood flow in the brain in the type 2 DM group as compared to placebo and to the non-diabetic group over a long-term period.
NCT04334707
Acute kidney injury (AKI) and chronic kidney disease (CKD) impose a significant global health burden. Yet, no effective therapies currently exist for AKI, and only a few are available for CKD. Despite significant effort from industry and academia, development of pharmacologic therapies for AKI and CKD has been hampered by: Non-predictive animal models The inability to identify and prioritize human targets The limited availability of human kidney biopsy tissue A poor understanding of AKI and CKD heterogeneity Historically, AKI and CKD have been described as single, uniform diseases. However, growing consensus suggests that different disease pathways lead to different subgroups of AKI and CKD (AKIs and CKDs). Access to human kidney biopsy tissue is a critical first step to define disease heterogeneity and determine the precise molecular pathways that will facilitate identification of specific drug targets and ultimately enable individualized care for people with AKI and CKD. A number of research centers across the United States are collaborating to bring state-of-the-art technologies together to: * Ethically obtain and evaluate kidney biopsies from participants with AKI or CKD * Define disease subgroups * Create a kidney tissue atlas * Identify critical cells, pathways, and targets for novel therapies The KPMP is made up of three distinct, but highly interactive, activity groups: * Recruitment Sites: The recruitment sites (RS) are responsible for recruiting participants with AKI or CKD into the longitudinal study and performing the kidney biopsy. * Tissue Interrogation Sites: The tissue interrogation sites (TIS) are responsible for developing and using innovative technologies to analyze the biopsy tissue. * Central Hub: The central hub is responsible for aggregating, analyzing, and visualizing the generated data and providing scientific, infrastructure, and administrative support for the KPMP consortium.
NCT02395601
First in human, open-label, sequential dose escalation and expansion study of CPI-1205 in patients with progressive B-cell lymphomas. CPI-1205 is a small molecule inhibitor of EZH2.
NCT02789657
Neoadjuvant therapy is given to breast cancer patients whose cancers are relatively large or have spread to lymph nodes or both. The primary goal of this treatment is to prevent the cancer from coming back (recurring) elsewhere in the body, but if it makes the cancer in the breast and lymph nodes shrink it might be easier to remove. This could allow a patient to have a lumpectomy instead of a mastectomy and reduce the number of lymph nodes that the surgeon has to remove. In some cases, the neoadjuvant therapy works so well that it kills all of the cancer in the breast and lymph nodes. This is referred to as a pathologic complete response (pCR). Patients who achieve a pCR have a much lower risk of the cancer recurring elsewhere in their bodies. Investigators aren't sure which chemotherapy drugs work best with the HER2-targeted drugs, and what combination of these drugs causes the fewest side effects.Thus, this study has two main goals: 1. To find out if treatment with wPCbTP, weekly paclitaxel and carboplatin given with trastuzumab and pertuzumab every 3 weeks, leads to as many pCRs as TCHP in patients with HER2-positive breast cancer, but has fewer side effects. 2. To find out if HER2-positive patients whose cancers are not responding well after 12 weeks of wPCbTP get a better response when they are switched to a doxorubicin-containing regimen called AC for 4 cycles (8-12 weeks).
NCT02611830

NCT03186339
Prospective, multi-centre, multi-national registry with a follow-up of 3 months, in five European countries and Canada (Toronto), with elective patients undergoing TF-TAVI (n=120) and isolated SAVR (n=120), respectively and a control group of 50 patients receiving medical treatment only. All patient groups will fill in three different questionnaires to assess quality of life in 5 different languages (English, French, German, Italian and Spanish). One of these will be a new questionnaire, the Toronto Aortic Stenosis QoL (Quality of Life) questionnaire (TASQ).
NCT04318275
This study aims to explore a novel objective measurement for endometriosis-related pain. A variety of pain symptoms are associated with endometriosis, including dysmenorrhea, dyspareunia, dysuria, dyschezia and chronic pelvic pain. However, a clear characterization of pain typology and topology in populations with endometriosis, other gynecologic pathology, or a normal pelvis is lacking. Understanding the precise nature of the relationship between pain and endometriosis is important for the clinical management of affected women, given the body of evidence indicating that medical and surgical management for pain associated with endometriosis has been shown to be effective. Evaluating the relationship between pain and endometriosis, however, is challenging given that pain is difficult to measure and the mechanism by which endometriosis causes pain is not well understood. While previous studies have provided important data on the incidence of pelvic pain and endometriosis, little research has been done to assess both the typology and topology of pelvic pain, pain beyond the pelvis, endometriosis diagnosis, or severity of pain using operative findings and a standardized classification system.
