Oklahoma City, OK Paid Clinical Trials

This Phase III trial will examine the efficacy of computerized cognitive training methods on perceived cognitive impairment in breast cancer survivors. Read Less

This phase III trial studies how well bupropion works in reducing cancer related fatigue in cancer survivors. Cancer and its treatment can cause fatigue. Bupropion is a drug that is used to treat depression, as well as to help people quit smoking. It belongs to the family of drugs called antidepressants and works by increasing certain types of activity in the brain. Bupropion may reduce cancer-related fatigue by causing changes in inflammation and stress hormones. Read Less

This study compares treatment outcomes between patients of African American/Black (AA) ancestry and European American/White (EA) ancestry currently receiving immune checkpoint inhibitor treatment. Collecting samples of blood and saliva and health and treatment information from racially diverse patients receiving immune checkpoint inhibitor treatment over time may help doctors better understand health care disparities among all cancer patients.

Crohn's disease (CD) is a long-lasting condition causing inflammation that can affect any part of the gut. The purpose of this study is to evaluate the efficacy and safety of TAK-279 versus placebo in participants with moderately to severely active Crohn's disease (CD). The main aim of this study is to learn if the 3 different doses of TAK-279 reduce bowel inflammation and ulcers in the bowel compared to the placebo after 12 weeks of treatment. Another aim is to compare any medical problems that participants have when they take TAK-279 or placebo and how well the participants tolerate medical problems. An endoscopy will be used to check the bowel for inflammation. The participants will be treated with TAK-279 for 52 weeks (1 year). During the study, participants will visit their study clinic 15 times. Read Less

This is a prospective, single arm, multicenter, clinical trial designed to evaluate the safety and performance of the AltaValve System for the treatment of mitral regurgitation in a targeted patient population. Read Less

The objective of this randomized controlled trial (RCT) is to compare the clinical outcome of MitraClip™ device versus surgical repair in patients with severe primary MR who are at moderate surgical risk and whose mitral valve has been determined to be suitable for correction by MV repair surgery by the cardiac surgeon on the local site heart team.

Hydroxychloroquine (HCQ) is a systemic lupus erythematosus (SLE) medication that has been very effective in reducing lupus disease activity and keeping patients stable with reduced symptoms. Despite a track record of safety with regard to infection compared to traditional immunosuppressive agents, the risk of HCQ retinal toxicity escalates with continued use. Evaluation using sensitive standard of care approaches suggests nearly a third of patients accrue retinal damage. Data are needed to accurately weigh the balance between accumulating ocular exposure of HCQ versus the risk of disease flare in a population that may have more inactive disease than younger patients. The purpose of this trial is to address the safety of withdrawal of HCQ in SLE patients =60 years old. The central hypothesis is that HCQ can be safely discontinued in stable/quiescent patients assessed by validated disease activity and flare instruments in the context of serologic, cytokine and transcriptomic profiling. Patients will be randomized to either the placebo or active arm and followed every 2 months for one year to assess disease activity and flares. Read Less

Thrombotic thrombocytopenic purpura (or TTP for short) is a condition where blood clots form in small blood vessels throughout the body. The clots can limit or block the flow of oxygen-rich blood to the body's organs, such as the brain, kidneys, and heart. As a result, serious health problems can develop. The increased clotting that occurs in TTP uses up the cells that help the blood to clot, called platelets. With fewer platelets available in the blood, bleeding problems can also occur. People who have TTP may bleed underneath the skin forming purple bruises, or purpura. TTP also can cause anemia, a condition in which red blood cells break apart faster than the body can replace them, leading to fewer red blood cells than in normal. TTP is caused by a lack of activity in the ADAMTS13 enzyme, a protein in the blood involved in controlling clotting of the blood. The ADAMTS13 enzyme breaks up another blood protein called von Willebrand factor that forms blood clots by clumping together with platelets. Some people are born with this condition, while others develop the condition during their life. Many people who are born with TTP experience frequent flare-ups that need to be treated right away. TAK-755 is a medicine that replaces ADAMTS13 and may prevent or control TTP flare-ups, called acute TTP events. The main aim of the study is to check for side effects of long-term treatment with TAK-755. Treatment will be given in 2 ways: 1. TAK-755 treatment given either every week or every other week to prevent acute TTP events from happening (the "prophylactic" cohort). 2. TAK-755 treatment given to control an acute TTP event when it happens (the "on-demand" cohort). Participants in the prophylactic cohort will receive treatment in the clinic or at home for up to approximately 3 years. They will visit the clinic at least every 12 weeks. Participants in the on-demand cohort will receive daily treatment for the acute TTP event until the flare-up has gotten better. They will have a follow-up visit at the clinic 4 weeks later.

The study will enroll 200 women newly diagnosed with peripartum cardiomyopathy within 5 months postpartum in a randomized placebo controlled trial of bromocriptine therapy to evaluate its impact on myocardial recovery and clinical outcomes. Given that bromocriptine prevents breastfeeding, an additional 50 women with peripartum cardiomyopathy excluded from the trial due to a desire to continue breastfeeding but meeting all other entry criteria will be followed in an observational cohort.

This study is an access and distribution protocol for unlicensed cryopreserved cord blood units (CBUs) in pediatric and adult patients with hematologic malignancies and other indications. Read Less

This research trial studies biomarkers in tumor tissue samples from patients with newly diagnosed neuroblastoma or ganglioneuroblastoma. Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer. Read Less
