The purpose of this study is to compare the effects of 2 different levels of exercise intensity and to learn more about effects of aerobic exercise for people with Parkinson’s disease (PD). This study will help us better understand what exercise guidelines should be used in the future.

This phase III trial studies brentuximab vedotin and combination chemotherapy to see how well they work compared to combination chemotherapy alone in treating children and young adults with stage IIB with bulk, stage IIIB, IVA, or IVB Hodgkin lymphoma. Combinations of biological substances in brentuximab vedotin may be able to carry cancer-killing substances directly to Hodgkin lymphoma cells. Chemotherapy drugs, such as doxorubicin hydrochloride, bleomycin sulfate, vincristine sulfate, etoposide, prednisone, and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known if combination chemotherapy is more effective with or without brentuximab vedotin in treating children with high-risk Hodgkin lymphoma.

The aim of this study is to obtain newborn blood spots (NBS) and tumor specimens for children and adolescents diagnosed with malignant neoplasms.

This ComboMATCH treatment trial compares the usual treatment of modified leucovorin, fluorouracil and oxaliplatin (mFOLFOX6) chemotherapy to using binimetinib plus mFOLFOX6 chemotherapy to shrink tumors in patients with biliary tract cancers that have spread to other places in the body (advanced) and had progression of cancer after previous treatments (2nd line setting).

This is study to determine if a new drug, camizestrant, improves outcomes compared to usual adjuvant endocrine therapy for people who have ER+/HER2- early breast cancer with intermediate-high or high risk for disease recurrence. People who have completed initial therapy (with or without chemotherapy) are eligible for the trial. Treatment is planned to continue for 7 years.

The purpose of our research study is to increase our understanding on the human lung immune response to infection. We aim to use this knowledge to develop novel approaches on the prevention and treatment of lung infections. To accomplish this, we plan to obtain cells from the airways and blood of healthy volunteers to perform immune experiments.

This first-in-human study will evaluate the safety, tolerability, pharmacokinetics, and antitumor activity of TORL-1-23 in patients with advanced cancer.

This research is being to see if a new 3D simulation model is helpful in teaching patients about care of their stomas after surgery. We expect that people will be in this research study for 3-6 months depending on the timing of surgery and postoperative visits. The number of preoperative and postoperative visits, physician exams, scans, X-rays, and laboratory tests for preparation for surgery or after the surgery does not change because of this study.

This study is to investigate if robotic assisted laparoscopy (small incision surgery), is worse than open surgery (otherwise known as a laparotomy) when performing a radical hysterectomy for cervical cancer. Previous research has been done and shown that patients receiving laparoscopy had an increased risk of recurrence of their cervical cancer. But since that time a lot has been learned and improvements have been made, hence why we are relooking at the differences between the two surgical approaches.

The goal of this study is to see if using in-home sleep activity monitoring may help understand sleep problems that occur before and after surgical treatment for Cushing Disease.

The purpose of this study is to learn about the safety and efficacy of PC945 when given in combination with the antifungal therapy that is normally given for this condition, also known as the standard of care (SoC). This study will also assess how PC945 is processed in the body (e.g., distributed, transformed, and removed) by measuring the levels of PC945 in your blood and lungs; this is called pharmacokinetics (PK).

The main purpose of this study is to look at how safe and well tolerated the study drug is in combination with ribociclib (Group 1) or alpelisib (Group 2), the levels of the study drug and ribociclib or alpelisib in your blood, and how your body and your cancer respond.

The purpose of this study is to determine the most effective ways to get rid of Staph aureus on body surfaces before surgery. We will determine if the participants can effectively get rid of the bacteria with the simple application of various treatment methods assigned to them. We will study if these methods are useful and cost effective in preventing the infections after surgery.

The goal of this current study is to test whether men with prostate cancer that is getting worse after treatment with hormone therapy and abiraterone respond better to alternating treatment with testosterone and enzalutamide vs. enzalutamide alone. We are testing to see which is better at stopping tumor growth that can be seen on a bone scan or CT scan and the effect of each regimen on lowering Prostate Specific Antigen (PSA values). Participants will be in the study for 6 to 24 months.

A study to test a medicine (fitusiran) injected under the skin for preventing bleeding episodes in male adolescent or adult participants with severe Hemophilia.

The clear layer at the front of the eye that covers the pupil and iris (colored part of the eye) is called the “cornea”. When the cornea is damaged, it normally heals within a few days but it may take up to 2 weeks depending on the size and depth of the defect (wound). Some corneal defects heal much slower than expected. A defect in the cornea that fails to heal within the normal time of 2 weeks despite using the best available medicines and procedures, is known as Persistent Corneal Epithelial Defect (or PCED for short). The purpose of this research study is to evaluate the safety, tolerability, and effectiveness (risks and benefits) of of NEXAGON ophthalmic gel for the treatment of PCEDs.

The primary research element is to determine whether a graft-versus-host disease (GVHD) prophylaxis regimen of post-transplant cyclophosphamide, tacrolimus and MMF will reduce the likelihood of chronic GVHD in patients receiving a standard hematopoietic myeloablative stem cell transplant. The treatment related components of this protocol are established clinical practices. We are looking at cumulative incidence of chronic GVHD requiring systemic immunosuppressive treatment at 1 year post-transplant.

This research study is for people who have Hidradenitis Suppurativa (HS) and it is moderate or severe in intensity and have been treated with at least one conventional therapy for HS. This study involves the investigational drug SBT777101, which is created by genetically modifying a patient’s own immune cells. The word “investigational” means that this drug has not been approved by the U.S. Food and Drug Administration (FDA) for marketing. SBT777101 is being developed to treat people with hidradenitis suppurativa (HS).

We are investigating how paired non-invasive electrical stimulation of surface body regions and sound changes sound perception and tinnitus. Body stimulation regions include: external ear/behind the ear, shoulder, neck, forearm, hand, and upper arm. We aim to better understand the optimal conditions of this paired stimulation, which opens opportunities for applying this method to improving hearing loss or tinnitus. We are studying three groups of people: those with normal hearing, those with mild to moderate hearing loss, and those with tinnitus.

Nephrotic syndrome is a condition which affects the kidneys causing them to leak protein from the blood into the urine. Nephrotic syndrome is a disease that can improve (remission) and worsen (relapse) at different times throughout childhood. By collecting health information and laboratory samples, our goal is to learn more about these kidney diseases and find better ways to prevent and treat people with nephrotic syndrome. New knowledge will be shared with researchers and the public.

The objective of this study is to describe how activation of distinct pathways in and around the subthalamic nucleus (STN) and internal segment of the globus pallidus (GPi) correlate to changes in sleep outcomes in movement disorders patients after deep brain stimulation (DBS) surgery targeting these structures.

Levosimendan has not been approved by the FDA to treat people who have PH-HFpEF or approved to be taken by mouth (orally). In this study, we will measure the amount of levosimendan in blood at various times and evaluate the change in participants 6-Minute Walk Distance.

This research is being performed to examine how the spleen moves during breathing in various body positions and breathing conditions. Physical measurements of the participant's body will be recorded (weight, height, and body dimensions) and then noninvasive recordings of the spleen and breathing patterns will be recorded. The spleen motion will be measured using standard abdominal ultrasound imaging, and breathing will be measured with accelerometers (small devices about the size of a quarter that measure the movement of the chest during breathing).

This study aims to investigate whether there is difference in ankle position sense acuity between people with Parkinson's with freezing of gait and without freezing of gait. It also examines the relationship between position sense acuity and severity of freezing of gait, and gait measurements.

This is a study of persons who do and do not stutter between ages 7 and 65 years. This study is trying to figure out how attention skills influence memory, language, and speech fluency skills.

The purpose of this study is to test the safety and effectiveness of Copper Cu 64 PSMA I&T in detecting lesions during a PET scan. This study is open to men with newly diagnosed prostate cancer who plan to have a prostatectomy and lymph node removal. Copper Cu 64 PSMA I&T is an investigational PET imaging agent, given to you via IV injection, similar to the way other imaging agents are used in many other types of scans. Cu 64 specifically targets the prostate specific membrane antigen (PSMA) that is found on the surface of metastatic prostate cancer cells. Increased image contrast may make it easier for the doctor to see smaller lesions compared to other imaging agents.

We want to see if we can lower the chance of bladder cancer growing or spreading by using a type of chemotherapy instilled in the bladder, Gemcitabine and Docetaxel. The usual approach for patients who are not in a study is treatment with Transurethral surgery of bladder tumor (TURBT) followed by instillations of Bacillus Calmette-Guerin (BCG) immunotherapy into the bladder via a catheter.

The purpose of this study is to compare the treatment of carboplatin/paclitaxel and letrozole hormonal therapy to letrozole alone. Letrozole is a drug called an aromatase inhibitor, which indirectly stops the body from producing estrogen. The use of the hormonal therapy drug, letrozole without chemotherapy may shrink or stabilize your cancer in the same way that chemotherapy also does, but without the added side effects of chemotherapy. Half of women in this study will receive letrozole with paclitaxel/carboplatin and the other half will receive letrozole alone.

The study is divided into two portions. In the first phase, we want to test the safety of a drug called ipatasertib, by testing different doses of the drug to see which dose is safer for people when given in combination with a fixed dose of a drug called megestrol acetate (MA). In Phase II, we are studying how safe the treatment is and how well it works. We are doing this study because we want to find out if this approach is better or worse than the usual approach for endometrial cancer.

This research study is designed to evaluate a new treatment approach for patients with chronic heart failure. This study will assess the effectiveness and safety of a new medical device, the AquaPass system, in managing the accumulation of fluids in the body that persists despite standard medical treatment. The purpose of this study is to understand if the use of the AquaPass System with medication treatment results in increased fluid removal compared to only regular medication treatment.
