There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this study is to test whether treatment-resistant late life depression is associated with declines in memory and attention and brain structure and function.
A Multi-Center, Open-Label, Randomized Phase 3 Trial Comparing the Safety and Efficacy of 177Lu-PSMA-I&T versus Hormone Therapy in Patients with Metastatic Castration-Resistant Prostate Cancer.
This phase II trial studies the effect of pembrolizumab in treating patients with multiple myeloma that is growing, spreading, or getting worse (progressing) on chimeric antigen receptor (CAR)-T cell therapy. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
Parents use social media as an important parenting tool and source for health information. Using social media data to examine public opinion has had an early impact in public health and in cancer control and prevention efforts, including about the human papillomavirus (HPV) vaccine. A next step in this area of research is to develop and share messages on social media with parents to help inform and educate them about the HPV vaccine - ultimately assisting them with their decision to vaccinate their child. This study will evaluate the efficacy of social media messages through Twitter, using a randomized controlled trial to determine what types of messages resonate with parents. The investigators will examine differences between two types of messages - narrative messages (i.e., stories) and non-narrative messages (i.e., numbers and facts).
This study investigates brain reorganization and behavioral responses in chronic pain with opioid exposure in Chronic Back Pain (CBP).
This clinical trial test whether taking part in a diet support intervention will help with patients nutrition and quality of life after surgery for esophagus or stomach cancer. The information learned by doing this research study may help patients get more information and/or support on eating after esophagus and stomach cancer surgery.
This study will be a placebo-controlled, double-blind, randomized, phase 3 study in participants with Atherosclerotic Cardiovascular Disease (ASCVD) who are not adequately controlled despite maximally tolerated lipid-lowering therapy.
This is an observational study in which patient data from the past on men with prostate cancer are studied. Cancer is a condition in which the body cannot control the growth of cells and tumors may form. If tumors form in the prostate, male sex hormones (androgens) can sometimes help the cancer spread and grow. Cancer that spreads to other parts of the body is called metastasis. Androgens are mainly made in the testicles. There are treatments available for men with prostate cancer to lower the levels of these hormones in the body. These treatments are called androgen deprivation therapy (ADT). Some men with prostate cancer respond to ADT, but in some cases, prostate cancer may overcome the therapy and worsen despite low androgens levels. Second generation androgen receptor inhibitors (SGARIs) including darolutamide, apalutamide, and enzalutamide are available for the treatment of prostate cancer in addition to ADT. SGARIs work by blocking androgens from attaching to proteins in cancer cells in the prostate. Clinical studies have shown that men with prostate cancer benefit from these treatments. But besides benefits, unfavorable reactions related to these treatments also influence which treatment is chosen, if the treatment is taken as intended or if it is even stopped. Unfavorable reactions observed for darolutamide, apalutamide, and enzalutamide differ from each other. In clinical trials, severe unfavorable reactions occurred less often for darolutamide. But information on how unfavorable reactions of each treatment influence their intake in actual or "real-world" prostate cancer treatment is missing. The main aim of this observational study is to learn to what extent SGARI treatments are taken as prescribed and how often their intake is completely stopped. To find this out, researchers will collect available treatment data of adult men with prostate cancer from the United States who started SGARI treatments between August 2019 and March 2021. The data will be drawn from the IQVIA database. For each man, data from up to 1 year prior SGARI treatment until at least 3 months after treatment start (up to the 30 June 2021) will be collected. The researchers will look at the percentage of men who: - completely stopped to take their treatment or - took the treatment as prescribed. The results for each treatment (darolutamide, apalutamide, and enzalutamide) will then be compared to find possible differences. There will be no required visits with a study doctor or required tests in this study since only patient data from the past are studied.
