NCT03250247
The purpose of this study is to determine if the use of image-guided, endovascular therapy (EVT) is an effective strategy with which to reduce Post Thrombotic Syndrome (PTS) disease severity and improve quality of life in patients with established disabling iliac-obstructive post thrombotic syndrome (DIO-PTS).
NCT01730937
This randomized phase III trial studies sorafenib tosylate and stereotactic body radiation therapy to see how well they work compared to sorafenib tosylate alone in treating patients with liver cancer. Sorafenib tosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Stereotactic body radiation therapy may be able to send the radiation dose directly to the tumor and cause less damage to normal tissue. Giving sorafenib tosylate together with stereotactic body radiation therapy may kill more tumor cells.
NCT03598790
This is a study to evaluate the long-term safety and tolerability of bimekizumab in adult subjects with moderate to severe chronic plaque psoriasis (PSO).
NCT04421573
PTSD is a chronic mental health condition that drastically reduces an individual's quality of life Dextrose injection with a small needle has been used for chronic pain patients and observational results have shown it to be effective in reducing anxiety, brain fog, and depression in patients with PTSD. This randomized trial will compare dextrose injection with a delayed/usual treatment control.
NCT05102370
Study researchers think that a drug called enasidenib may help people with clonal cytopenia of undetermined significance (CCUS) because the drug blocks the mutated IDH2 protein, which may improve blood cell counts. The purpose of this study is to find out whether enasidenib is a safe and effective treatment for CCUS.
NCT05710406
This phase II/III trial compares treatment with encorafenib and cetuximab to usual care (patient observation) for reducing the chance of cancer recurrence after standard surgery and chemotherapy in patients with BRAF-mutated stage IIB-III colon cancer. Encorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Cetuximab is in a class of medications called monoclonal antibodies. It binds to a protein called EGFR, which is found on some types of tumor cells. This may help keep tumor cells from growing. Giving encorafenib and cetuximab after standard surgery and chemotherapy may be more effective at reducing the chance of cancer recurrence compared to the usual patient observation.
NCT04114981
This phase III trial studies how well single fraction stereotactic radiosurgery works compared with fractionated stereotactic radiosurgery in treating patients with cancer that has spread to the brain from other parts of the body and has been removed by surgery. Single fraction stereotactic radiosurgery is a specialized radiation therapy that delivers a single, high dose of radiation directly to the tumor and may cause less damage to normal tissue. Fractionated stereotactic radiosurgery delivers multiple, smaller doses of radiation therapy over time. This study may help doctors find out if fractionated stereotactic radiosurgery is better or worse than the usual approach with single fraction stereotactic radiosurgery.
NCT03432286
The main purpose of this study is to evaulate the efficacy and safety of galcanezumab in participants 6 to 17 years of age for the preventive treatment of episodic migraine. The primary objective is to demonstrate the superiority of galcanezumab versus placebo in the reduction of monthly migraine headache days across the 3-month double-blind treatment period.
NCT05145491
Vitrectomy to remove an epiretinal membrane (ERM) is one of the most common procedures performed by retinal surgeons. Patients who present with significant macular changes on optical coherence tomography (OCT) but relatively good vision are often advised to defer surgery until vision declines to 20/40 or worse. However, it is unknown if delaying surgery, which allows the foveal architecture to remain compromised and potentially to deteriorate, results in worse visual acuity outcomes than if surgery is performed earlier. In addition, there is a need to better understand predictors of outcomes when surgery is performed and predictors of progression when surgery is deferred. Finally, one of the most common presenting symptoms from an ERM is distortion or metamorphopsia. There are several objective measures of metamorphopsia but none have ever been employed to evaluate ERMs in a randomized clinical trial (RCT) and their usefulness is unknown. The purposes of this study are to better understand the optimal timing of surgery to produce the best visual result, to better understand predictors of outcomes in those who undergo surgery and predictors of progression in those whose are observed, and to better characterize and evaluate the usefulness of metamorphopsia and reading speed measures.
NCT04243499
Part 1 will be a dose escalation study of IV ICT01 (a monoclonal antibody targeting BTN3A) as monotherapy in patients with advanced solid or hematologic tumors, followed by a cohort examining the combination of ICT01 plus pembrolizumab (Keytruda). Part 2 will be a cohort expansion into 2 solid tumor indications and one hematologic malignancy for ICT01 monotherapy, and 3 solid tumor indications for the combination of ICT01 plus pembrolizumab.
NCT06111781
The goal of this clinical trial is to measure the toxicity and effectiveness of the following treatments for cFIR/cgUIR prostate cancer patients. Stereotactic body radiotherapy (SBRT) alone or Stereotactic body radiotherapy (SBRT) combined with Ultrashort GNRH Antagonist called Relugolix (an oral drug). Treatments will be randomly assigned to study patients. The main questions it aims to answer are the following: 1. Whether the proportion of men who undergo SUGAR have a superior rate of attaining PSA nadir of \<= 0.2 compared to SBRT alone, and 2. Whether SUGAR is superior to historical rates of minimal clinically important decline (MCID) in sexual and hormonal function at 6 months for patients undergoing 6 months of androgen deprivation therapy (ADT) Men aged 18+ with cFIR/cgUIR will be enrolled. Specifically, patients must meet one of the following 2 criteria: 1) Gleason score must be Gleason 3+4 with a PSA \< 20 ng/mL, or 2) Gleason 6 (3+3) and PSA \> 10 ng/mL and \< 20 ng mL.
NCT03168776

This prospective, global, multi-center, randomized 2:1, single blind study will enroll up to 1632 subjects at up to 130 investigational sites in North America, Japan, and Europe. Subjects will have clinical follow-up in-hospital and at 30 days, 6 months, 12 months, and 2, 3, 4, and 5 years.
NCT06599099
This study is only enrolling at Baylor College of Medicine. The other research locations listed serve to support data analysis only. This research study is to investigate the use of technology called Deep Brain Stimulation (DBS) to potentially improve Treatment-Resistant Bipolar Depression (TRBD) symptoms in patients with severe cases. DBS involves the surgical implantation of leads and electrodes into specific areas of the brain, which are thought to influence the disease. A pack implanted in the chest, called the neurotransmitter, keeps the electrical current coursing to the brain through a wire that connects the neurotransmitter and electrodes. It is believed DBS may restore balance to dysfunctional brain circuitry implicated in TRBD. The goal of this study is to enhance current approaches to DBS targeting in the brain and to use a novel approach to find a better and more reliable system for TRBD treatment. Its important for participants to understand that this is an investigational study where there could be a lack of effectiveness in improving TRBD symptoms. There may be no directly benefit from taking part in this study. This study is expected to last 20 months and involves 3 main steps. 1. Medical, psychiatric, and cognitive evaluations. 2. Implantation of a brain stimulation system. 3. Follow up after implantation of device, including programming, recording, and psychiatric testing. There are risks and benefits to this study which need to be considered when deciding to participate or not. Some of the risks are from surgery, the DBS device and programming, the tests involved, and potential loss of confidentiality, as well as other unknown risks. Some of the more serious risks involved in this study and the percentage that they occur: 1. Bleeding inside the Brain (1 to 2 percent). 2. Infection from the procedures (3 percent) 3. Seizure caused from the procedures (1.2 percent) However, the benefit of this study is that it may help relieve or decrease TRBD symptoms. This form of treatment has shown to reduce symptom severity in other cases. This could potentially improve quality of life and activities in daily routines. There is also a potential benefit to society in that the data the investigators will obtain from this study may help increase the understanding of the mechanisms underlying TRBD symptoms, as well as enhanced Deep Brain Stimulation techniques. Study participation is expected to last 20 months from the time the DBS device is activated and should include approximately 23 visits. These visits also include 8 separate, 24 hour stays at the Menninger NeuroBehvaioral Monitoring Unit (NBU). These 24-hour sessions will occur at multiple points throughout the study (1 week prior to surgery, the week preceding device activation, the week following activation, then after 2 weeks, 4 weeks, 6 months, 9 months, and 12 months). Participants will need to stay locally for the week of the NBU stay (typically Monday through Friday). Study visits will include clinician administered assessments and questionnaires, subject reported assessments, neuropsychological testing, and mobile behavioral assessments which will occur around 23 visits over the course of 20 months.
NCT05382208
The purpose of this study is to determine if doxycycline will reduce progression of emphysema in people living with HIV. The secondary objectives are to examine the effects of doxycycline on change in quantity of emphysema, six minute walk distance, patient reported outcomes, ratio of forced expiratory volume in 1 second and forced vital capacity. Secondary objectives will also describe the safety and tolerability of doxycycline and determine if doxycycline is associated with development of antibiotic-resistant bacterial infections.
NCT05195918
The primary purpose of this multi-center, double-blind, placebo-controlled, dose-ranging Phase I study is to assess the safety of a purified from green tea, EGCG, in patients with idiopathic pulmonary fibrosis (IPF) as a potential novel treatment for pulmonary fibrosis.
NCT05622682
This observational study aims to assess recovery of the immune system and immunity to vaccine-preventable diseases in children, adolescents, and young adults who recently completed treatment for acute lymphoblastic leukemia (ALL). Several children's hospitals in the United States are participating in the study, which will enroll up to 100 pediatric participants. The study is intended to determine the rate of infection after leukemia treatment and to inform future studies and recommendations about whether children and adolescents who have leukemia should receive additional vaccine doses or boosters after treatment.
NCT06130540
This study will examine how intravenous (i.v.) Secukinumab will be processed in the body (pharmacokinetics \[PK\]) and whether it will be safe and tolerable after multiple doses of i.v. Secukinumab infusion in adult patients with giant cell arteritis (GCA) or polymyalgia rheumatica (PMR).
NCT06716450
To help reach the undiagnosed living with HIV and/or syphilis in Canada, self-tests for HIV and Syphilis may have substantial utility for increased identification of infected individuals through their relative ease of use and portability, as well as their ability to deliver rapid, actionable results while the care provider still has access to the patient. MedMira Laboratories Inc. (Halifax, Nova Scotia, Canada) has developed a point-of-care (POC) test to detect HIV and Syphilis antibodies in fingerstick blood samples that is under final review by Health Canada for use by trained Healthcare professionals. A self-test version of this test, with simplified instructions for use has been developed for investigational studies. The goal of the following study sponsored by REACH Nexus is to provide evidence that untrained lay persons / intended users can perform the Multiplo Tp/HIV Self-Test without any increased risk of obtaining erroneous results.
