NCT07504601
Background: Opioid drugs are often prescribed for acute and chronic pain. But these drugs are addictive, and they lead to more than 14,000 overdose deaths in the United States each year. Researchers want to find new drugs that relieve pain but are not addictive. This study will test whether a single dose of an experimental drug called (2R,6R)-hydroxynorketamine (HNK) can help reduce short term pain in healthy adults. HNK is related to ketamine. Studies suggest HNK might be as effective as ketamine at reducing pain but that it might have fewer side effects. In this study we will test how HNK affects pain and emotion. The results of this study may help us understand whether HNK has pain relieving effects and how it works in the brain, which could inform future pain treatments. Objective: To test the study drug \[(2R,6R)-hydroxynorketamine (HNK)\] for treating acute pain in healthy people. Eligibility: Healthy people aged 18 to 60 years. Design; Up to 92 healthy volunteers between 18 and 60 years old without chronic pain or psychiatric conditions will participate in the study. The study will take place at the NIH Clinical Center in Bethesda, Maryland. Each participant s involvement will last up to two months. The overall study is expected to last about three years (36 months). The study has 2 parts. In part 1, participants will have up to 2 clinic visits. They will be screened and have blood draws to make sure they're eligible for the study. They will complete sensory testing and have MRI brain scans. Sensory testing involves feeling and rating painful and non-painful sensations. These may include hot or cold temperatures, pinches or squeezes, and being touched with brushes or pinpricks. Eligible participants will have an imaging scan that shows brain activity: During the scan, they will rate heat, hear pleasant or unpleasant sounds, and view unpleasant or pleasant pictures. After completing part 1, eligible participants will be invited to part 2, which includes overnight stays at NIH. In part 2, participants will be assigned to either a treatment group or a no-treatment group. The treatment group will have 2 overnight visits of 2 nights each. The visits will be 1 to 3 weeks apart. For one of the visits, treatment group participants will receive the study drug HNK. For the other visit, they will receive a placebo. A placebo looks just like the study drug but contains no medicine. HNK and placebo are given through a tube inserted into a vein in the arm. The sensory tests, blood draws, and MRI scans will be repeated at each visit. Participants will not be told whether they got the drug or placebo on each visit. The nontreatment group will have 1 overnight visit. They will not receive the drug or placebo. The sensory tests, blood draws, and MRI scans will be repeated. Participants cannot drink alcohol, use recreational drugs, or take certain other kinds of medicine or supplements during the study.
NCT06487481
Background: Adrenocortical carcinoma (ACC) is a rare cancer of the adrenal glands. ACC often returns after tumors are removed with surgery. Less than 35% of people with ACC survive 5 years after diagnosis. Objective: To test a new type of external beam RT before surgery in people with ACC. Eligibility: People aged 18 years and older with ACC that came back after treatment but may be safely removed with surgery. Design: Participants will be screened. They will have a physical exam with blood and urine tests. They will have tests of their heart function. They will have imaging scans. A small sample of tumor tissue may be collected if one is not available. They will undergo laparoscopy: Small incisions will be made in the abdomen so that a thin tube with a light and camera can be inserted to view the organs. RT comes from a machine that aims radiation at tumors. Participants will receive preoperative RT in daily fractions over approximately 2-3 weeks, followed by a planned surgical resection about 4 weeks after the completion of RT. Visits will last 30 to 60 minutes. Participants will undergo surgery to remove their tumors about 4 weeks after they finish RT. They will stay in the hospital 1 to 3 weeks after surgery. Participants will have follow-up visits for 10 years after surgery.
NCT07215858
Background: Influenza (flu) infections are a serious global health threat. Each year, between 3 and 5 million people get the flu, and up to 500,000 die from it. Current vaccines protect against seasonal flus, but broader vaccines are needed to protect against potential flu pandemics. Objective: To test an experimental flu vaccine. Eligibility: Healthy people aged 18 to 55 years. Design: The study will last 5 to 8 months and has 2 phases, A and B. The study vaccine will be given either as a shot in the arm or as a nasal spray. Participants will receive 1 of 3 combinations: (1) study vaccine in the nose and placebo in the arm; (2) placebo in the nose and study vaccine in the arm; or (3) placebo in the nose and placebo in the arm. A placebo is just like the real vaccine but contains no active ingredients. Phase A: Participants will have 5 clinic visits over 56 days. They will receive a shot and a nasal spray at 2 of the visits, 28 days apart. At each visit, they will have a physical exam, with tests of their blood, urine, and nasal secretions. They will check their temperature at home and record any symptoms for 7 days after each vaccine. Phase B: Participants will stay in the hospital for at least 9 days. They will be infected with a flu virus. They will provide blood, urine, and nasal fluid samples. They will have tests of their heart function. They will remain in the hospital until they test negative for the flu 2 days in a row. They will have 2 follow-up visits, 4 and 8 weeks after leaving the hospital. ...

Additionally, the study evaluates the safety and tolerability of KL1333.
NCT07099092
Background: Little is known about how different regions of the brain responsible for the human sense of smell guide behaviors. In this study, researchers use a technique called transcranial ultrasound stimulation (TUS) to learn how odors affect the brain and behavior. Objective: To learn more about how the human sense of smell works. Eligibility: Healthy people aged 18 to 45 years who are right-handed. Design: Participants can volunteer for up to 2 different experiments. Each experiment requires 5 visits, each about 1 week apart. Food, alcohol, and caffeine may be limited before visits. At the start of each visit, participants will answer questions about their health and how well they slept. Their sense of smell will be assessed. Some visits may include tasks on a computer: While doing these tasks, participants may be asked to smell different odors, look at pictures, and listen to sounds. They will wear devices to track breathing, blood pressure, pulse, and other body responses to the tasks. Some visits may include TUS: TUS uses ultrasound waves to briefly change brain activity. A gel will be applied to the scalp and hair, and a device will be placed against the participant s head. Participants may feel a tapping, pulling, and/or warm sensation on the skin underneath the device. They may also feel a twitch in their face, neck, arm, or leg muscles. Participants will do tasks before and after TUS. Some visits will include functional magnetic resonance imaging (fMRI) scans. fMRI uses magnet and radio waves to capture images of the activity inside the brain. Participants will lie on a table that slides into a tube. They will perform tasks inside the scanner.
NCT03737981
This phase III trial compares adding a new anti-cancer drug (venetoclax) to the usual treatment (ibrutinib plus obinutuzumab) in older patients with chronic lymphocytic leukemia who have not received previous treatment. The addition of venetoclax to the usual treatment might prevent chronic lymphocytic leukemia from returning. This trial also will investigate whether patients who receive ibrutinib plus obinutuzumab plus venetoclax and have no detectable chronic lymphocytic leukemia after 1 year of treatment, can stop taking ibrutinib. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Immunotherapy with obinutuzumab may induce changes in body's immune system and may interfere with the ability of cancer cells to grow and spread. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Giving ibrutinib and obinutuzumab with venetoclax may work better at treating chronic lymphocytic leukemia compared to ibrutinib and obinutuzumab.
NCT03220022
This phase I trial studies the side effect and best dose of ibrutinib in combination with rituximab, etoposide, prednisone, vincristine sulfate, cyclophosphamide, and doxorubicin hydrochloride in treating patients with human immunodeficiency virus (HIV)-positive stage II-IV diffuse large B-cell lymphomas. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as rituximab, may interfere with the ability of cancer cells to grow and spread. Drugs used in chemotherapy, such as etoposide, prednisone, vincristine sulfate, cyclophosphamide, and doxorubicin hydrochloride, 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. Giving ibrutinib and etoposide, prednisone, vincristine sulfate, cyclophosphamide, and doxorubicin hydrochloride may work better in treating patients with HIV-positive diffuse large B-cell lymphomas.
NCT05348733
This is an observational study in people with chronic kidney disease (CKD) and type 2 diabetes (T2D) who will be receiving finerenone. Kidneys filter extra water and waste out of the blood and make urine. CKD is a long-term, progressive, decrease in the kidneys' ability to filter the blood properly. In people with T2D, the body does not make enough of a hormone called insulin, or does not use insulin well enough, resulting in high blood sugar levels that can cause damage to the kidneys. As a result, CKD can occur as a complication of T2D. Finerenone works by blocking certain proteins, called mineralocorticoid receptors. An increased stimulation of these proteins is thought to damage the kidneys and the heart. By lowering their stimulation, finerenone reduces the risk of kidney disease progressively getting worse. Finerenone is available and approved for doctors to prescribe to people with CKD and T2D. Since it has only recently become available for these patients, there is a need for more information about the use of finerenone in the real-world setting. The main purpose of the study is to learn more about treatment patterns in people with CKD and T2D who just started or will start finerenone treatment as decided and prescribed by their doctor as part of their routine medical care. To answer this question, the researchers will collect data on: * Clinical characteristics (e.g., history of CKD and T2D, blood pressure, heart health) of the participants * Reasons for starting finerenone * Reasons for stopping finerenone early * How long participants have been taking finerenone (planned by their doctor compared to actual time it was taken) * Dosing of finerenone * Other medications used while taking finerenone The researchers will also collect data on medical problems (called adverse events) that the participants may have during the study. All adverse events are collected, even if they might not be related to the study treatment. Hyperkalemia, a medical term used to describe a potassium level in the blood that is higher than normal, is of special interest when finerenone is combined with some medications commonly taken to control blood pressure. Researchers want to know how often higher potassium levels occur, and when it leads to: * Stopping finerenone treatment too early * Dialysis (a medical procedure to filter the blood of extra water and waste) * Care in a hospital All data will come from medical records or from interviews study doctors will have with the participants during visits that take place during routine medical care. Participants in the US will be invited to provide voluntary blood and urine samples that could be analyzed later to better understand possible changes in protein or nucleic acid levels over time. Each participant will be in the study for 12 months. This time participating in the study may be shorter if their finerenone treatment is stopped early or the study comes to an end as planned in September 2027.
NCT04214067
This phase III trial compares whether the addition of pembrolizumab to radiation therapy is more effective than radiation therapy alone in reducing the risk of cancer coming back (recurrence) in patients with newly diagnosed stage I-II endometrial cancer. 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. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. The addition of pembrolizumab to radiation treatment may be more effective than radiation treatment alone in reducing cancer recurrence.
NCT05908084
The goal of this clinical trial is to compare the number of catheter-free days (CFD) and the rate and severity of any dialysis access-related infections between the ATEV and AVF groups over 12 months in patients with end-stage renal disease (ESRD) needing hemodialysis (HD). Participants will be stratified by location of the vascular access (forearm versus upper arm) and by type of AVF creation procedure planned by the surgeon at randomization (1-stage AVF versus 2-stage AVF). The comparator is an upper extremity arterio-venous fistula (AVF) for HD access surgically created per the institution's Standard of Care (SoC).
NCT07287098
This study will include two groups of patients: Cohort 1 and Cohort 2. Cohort 1: will help researchers learn how a medicine called imlunestrant (LY3484356) affects a specific type of breast cancer. Some patients will take both imlunestrant and another treatment to suppress their ovarian function. Some will take it without ovarian suppression. Researchers will compare the effects in breast cancer cells to those of another medicine called tamoxifen. All patients in this group will be premenopausal women who have a type of early breast cancer called estrogen receptor-positive, HER2-negative. The treatment in this group will last for up to 29 days. Cohort 2: will help researchers understand how imlunestrant affects the ovaries when it is taken without ovarian suppression. Researchers will compare the effects to those of another medicine called tamoxifen. This group will also include premenopausal women with the same type of breast cancer. The treatment in this group will last for up to 6 months.
NCT05967689
The purpose of this study is to evaluate the safety, efficacy and pharmacokinetics (PK) of zipalertinib in participants with locally advanced or metastatic Non-Small Cell Lung Cancer (NSCLC) harboring EGFR ex20ins mutations and other mutations.
NCT06079671
This is a phase III, randomized, double-blind, placebo-controlled, multi-center, global study to explore the efficacy and safety of volrustomig in women with high-risk LACC (FIGO 2018 stage IIIA to IVA cervical cancer) who have not progressed following platinum-based CCRT.
NCT07271186

The aim of the study is to see how safe and effective the study drugs are. The study is looking at several other research questions, including: * What side effects may happen from taking the study drug * How much study drug is in the blood at different times
NCT06274047
1. Personalize treatment for prostate cancer based on how aggressive the disease is and 2. Learn if apalutamide-based treatment can help to reduce fatigue and other side effects of treatment in participants who are being treated with radiation therapy for prostate cancer, as compared to standard therapy.
NCT07670156
This study focuses on a genetic condition that affects the Janus Kinase-Signal Transducer and Activator of Transcription (JAK-STAT) immune signaling pathway. A specific change in the DNA leads to overactivation of this pathway, which can result in immune dysregulation and related clinical symptoms. Currently, five genetic mutations are known to cause these JAK-STAT pathway driven immune disorders: STAT1, STAT3, STAT5B, STAT6, and JAK1 (collectively referred to as JAK-STAT disorders). This study is a basket clinical trial, meaning patients with these different but related genetic conditions are enrolled in the same study and treated with the same investigational therapy. The purpose of this study is to evaluate the safety and tolerability (ability to tolerate) of a drug called Upadacitinib in patients with JAK-STAT disorders with activating mutations. This drug belongs to a class of drug called Janus kinase (JAK) inhibitors, also known as JAKinibs. It is a type of immune system modulating medication that regulates (fixes) the JAK- STAT signaling pathway. Upadacitinib has been approved by the FDA for multiple immunological diseases and disorders. Presently, there is no FDA approved treatment for this group of JAK-STAT disorders. The study will also investigate immune factors in the blood to develop diagnosis methods that can be used in the future for better medical management of these disorders. The study consists of four phases: screening phase, open label phase, randomized withdrawal phase and maintenance phase. The study will last approximately 12 months. While in the study, participants will receive a once daily dose of Upadacitinib that best helps control their disease. During the study participants will be asked to answer questions about their health and medical history. They will also complete physical exams, blood tests, and other questionnaires.
