The TricValve® Transcatheter Bicaval Valve System is a bicaval transcatheter tricuspid valve replacement system, which includes the TricValve® Transcatheter Bicaval Valve for superior vena cava (SVC) and the TricValve® Transcatheter Bicaval Valve for inferior vena cava (IVC). The TricValve® Transcatheter Bicaval Valves are pre-mounted into the TricValve® Delivery System which is used for percutaneous access and delivery of the TricValve® Transcatheter Bicaval Valve in the vena cava. The system is a single use, sterile device compatible with all the valve sizes. The prostheses are implanted percutaneously into the inferior and superior vena cava without disturbing the native tricuspid valve. The device is made of bovine pericardium leaflets sutured on a nitinol self-expanding stent system.
NCT05498155
This study to learn more about olaparib and olaparib plus durvalumab combination therapy and also to better understand the studied disease, breast cancer, and associated health problems. Olaparib is a type of drug called a PARP (poly \[adenosine diphosphate-ribose\] polymerase) inhibitor. PARP inhibitors can destroy cancer cells that are not good at repairing DNA damage. Olaparib is also approved by US Food and Drug Administration (FDA), European Medicines Agency (EMA) and in other countries for treating women with BRCA-mutated, human epidermal growth factor receptor 2 (HER2)-negative metastatic breast cancer. Durvalumab is a type of anticancer drug called immunotherapy that targets cancer cells by blocking the signal that prevents the immune system from seeing the cancer cell. Your immune system can then attack and kill the cancer cells. Durvalumab is approved by the FDA and the EMA for the treatment of patients with locally advanced non-small cell lung cancer after receiving chemoradiation therapy and extensive-stage small cell lung cancer in combination with chemotherapy. Some parts of this study are experimental, which means that durvalumab and the combination of olaparib and durvalumab are still in the development stage for the treatment of breast cancer, and they are not approved for treatment of breast cancer, except for use in research studies like this.
NCT06416072
The APEX study is a multicenter, observational study designed to capture longitudinal follow-up of plasma biomarkers and cognitive and functional assessments on individuals who screen failed in the AHEAD study over approximately 4 years. Approximately 1000 participants will be enrolled across three groups: * Group A: Approximately 500 participants who are discordant on screening (plasma positive / Positron Emission Tomography (PET) negative), * Group B: Approximately 250 participants who are concordant on screening (plasma negative / PET negative), and * Group C: Approximately 250 participants selected from the individuals who previously screen failed prior to PET for the AHEAD study with oversampling of racial and ethnic populations underrepresented in Alzheimer's disease (AD) clinical trials. Primary Objectives: * Collect longitudinal cognitive and functional assessments and blood-based biomarker data * Evaluate, characterize, and compare the longitudinal cognitive and functional data between the three groups of participants * Compare longitudinal change across race and ethnicity, sex, and Apolipoprotein E (ApoE) status Exploratory Objectives: • Collect baseline amyloid PET on participants without prior amyloid PET data (Group C)
NCT04727151
TAC01-HER2 is a novel cell therapy that consists of genetically engineered autologous T cells expressing T-cell Antigen Coupler (TAC) that recognizes human epidermal growth factor receptor 2 (HER2). TAC directs T-cells to the targeted antigen (HER2), and once engaged with the target, activates them via the endogenous T cell receptor. This is an open-label, multicenter Phase 1/2 study that aims to establish safety, maximum tolerated dose (MTD) or recommended phase 2 dose (RP2D), pharmacokinetic profile and efficacy of TAC01-HER2 as a monotherapy, and in combination with pembrolizumab, in subjects with HER2 positive gastric and gastroesophageal adenocarcinoma.
NCT05064540

Patients will be randomized into two device cohorts and compared across the primary endpoints. Patients will be followed procedurally to discharge, at 1, 6, 12 months and annually through to 5 years (total follow-up commitment).
NCT06171737
The goal of this study is to increase shared decision making for patients considering treatment for severe aortic stenosis. The main questions it aims to answer are: * Do patient decision aids and clinician skills training course improve the quality of decisions, and do they work well for different patient populations? * Are heart clinics able to reach the majority of patients with decision aids before their specialist visit and do the majority of clinicians complete the training course? All participating sites will start in the usual care group and then will be randomly assigned a time to switch to the intervention group. Participants will complete surveys before and after their specialist visit. Researchers will compare data from patients seen during usual care with data from those seen after the interventions are implemented to see if there are improvements in the quality of decisions.
NCT02074839
The purpose of this Phase I, multicenter study is to evaluate the safety, pharmacokinetics, pharmacodynamics and clinical activity of AG-120 in advanced hematologic malignancies that harbor an IDH1 mutation. The first portion of the study is a dose escalation phase where cohorts of patients will receive ascending oral doses of AG-120 to determine maximum tolerated dose (MTD) and/or the recommended Phase II dose. The second portion of the study is a dose expansion phase where four cohorts of patients will receive AG-120 to further evaluate the safety, tolerability, and clinical activity of the recommended Phase II dose. Additionally, the study includes a substudy evaluating the safety and tolerability, clinical activity, pharmacokinetics, and pharmacodynamics of AG-120 in subjects with relapsed or refractory myelodysplastic syndrome with an IDH1 mutation. Anticipated time on study treatment is until disease progression or unacceptable toxicity occurs.
NCT03859700
Open-label, follow-up study for subjects who completed the EPITOPE study.
NCT03537014
The goal of this clinical trial is to learn if MDMA-assisted therapy is safe and effective in people with at least severe PTSD. The main question it aims to answer is: Do three sessions of MDMA-assisted therapy reduce PTSD symptoms? Researchers will compare three sessions of MDMA-assisted therapy with an initial dose of 80 to 120 mg to three sessions of placebo with therapy. Participants will undergo three preparatory sessions without any study drug, followed by three MDMA-assisted therapy or placebo with therapy sessions. Each medication session will be followed by three integrative therapy sessions without study drug.
NCT03072238
The purpose of this study is to evaluate the efficacy, safety, and pharmacokinetics of ipatasertib plus abiraterone and prednisone/prednisolone compared with placebo plus abiraterone and prednisone/prednisolone in participants with metastatic castrate-resistant prostate cancer (mCRPC).
NCT07011563
The goal of this study is to help young people talk to trusted adults (including their parents, but also other adults) about sexual health more openly and honestly- including how to prevent sexually transmitted diseases like HIV - while also respecting a young person's right to privacy. If youth don't have a parent they can talk to about sexual health, we want to help them find a trusted adult to talk to. We also want to help youth take control of their own health by learning about different ways to protect their health.
