A Study of TAK-411 in Adults With Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP)
Recruiting
CIDP is an autoimmune disease. This means that the body's germ fighting (immune) system attacks itself. In CIDP, the immune system attacks the protective covering around the nerves called myelin. Over time, these nerves lose their ability to send signals to the muscles in the body. This leads to muscle weakness and loss of sensation in arms and legs among other symptoms. Participants with CIDP can be treated with a protein called immunoglobulin (or IG). TAK-411 is a special type of immune globu... Read More

Serial Blood Count Study
Recruiting
The objective of the Serial Blood Count Study is to determine the utility of home monitoring of white blood cell (WBC) and absolute neutrophil counts (ANC) to diagnose cyclic neutropenia and distinguish between cyclic and severe congenital neutropenia (SCN). A new home monitoring device called Athelas One was granted an FDA 510K Class 2 clearance for evaluation of white blood count (WBC) and absolute neutrophil count (ANC). The investigators believe this device provides a unique and extremely va... Read More

Functional Assessment in Liver Transplantation
Recruiting
This will be a prospective cohort study of patients with liver disease. Subjects will undergo geriatric assessments of frailty, functional status, and disability using functional status measures at baseline and at every clinic visit in the pre-transplant setting. Subjects will also answer questions regarding quality of life, personality, and/or cognitive function. Subjects will again undergo assessments at every clinic visit through 12 months after transplant. Then, they will be followed annuall... Read More

Study of Radiation Therapy Followed by Atezolizumab in Stage II or III Non-small Cell Lung Cancer Patients
Recruiting
This phase II trial studies the side effects of radiation therapy followed by atezolizumab in treating patients with stage II or III non-small cell lung cancer. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more cancer cells and have fewer side effects. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to g... Read More

Post-Surgical Stereotactic Radiotherapy (SRT) Versus GammaTile-ROADS (Radiation One and Done Study)
Recruiting
This trial will be a randomized controlled study comparing the efficacy and safety of intraoperative radiation therapy using GammaTilesTM (GT) versus SRT 3-4 weeks following metastatic tumor resection which is the current standard of care.

Promoting Goals-of-Care Discussions for Patients With Memory Problems and Their Caregivers
Recruiting
The goal of this clinical trial is to improve communication among clinicians, patients with memory problems, and their family members. We are testing a way to help clinicians have better conversations to address patients' goals for their healthcare. To do this, we created a simple, short guide called the "Jumpstart Guide." The goal of this research study is to show that using this kind of guide is possible and can be helpful for patients and their families. Patients' clinicians may receive a Jum... Read More

Electronic Harm Reduction Treatment for Alcohol
Recruiting
The goal of this project is to transform a successful, face-to-face harm-reduction treatment (HaRT-A) into a digital format, creating eHaRT-A. This new platform is specifically designed for people who have experienced homelessness and an alcohol use disorder (AUD), living within the framework of permanent, supportive, Housing First (HF) facilities. We hypothesize eHaRT-A will be more effective than the standard HF services in reducing alcohol-related harm and improving the overall quality of lif... Read More

A Study to Compare Blinatumomab Alone to Blinatumomab With Nivolumab in Patients Diagnosed With First Relapse B-Cell Acute Lymphoblastic Leukemia (B-ALL)
Recruiting
This phase II trial studies the effect of nivolumab in combination with blinatumomab compared to blinatumomab alone in treating patients with B-cell acute lymphoblastic leukemia (B-ALL) that has come back (relapsed). Down syndrome patients with relapsed B-ALL are included in this study. Blinatumomab is an antibody, which is a protein that identifies and targets specific molecules in the body. Blinatumomab searches for and attaches itself to the cancer cell. Once attached, an immune response occu... Read More

A Study of Camizestrant in ER+/HER2- Early Breast Cancer After at Least 2 Years of Standard Adjuvant Endocrine Therapy
Recruiting
This is a Phase III open-label study to assess if camizestrant improves outcomes compared to standard endocrine therapy in patients with ER+/HER2 - early breast cancer with intermediate or high risk for disease recurrence who completed definitive locoregional therapy (with or without chemotherapy) and standard adjuvant endocrine therapy (ET) for at least 2 years and up to 5 years. The planned duration of treatment in either arm of the study is 60 months.

This study will be conducted in 2 parts. The first part is a phase 1 single-agent dose escalation, and dose optimization, study of tegavivint in patients with advanced HCC after failure of at least one line of prior systemic therapy. The second part of the study will begin with a brief dose escalation part for each combination (tegavivint plus cabozantinib or tegavivint plus lenvatinib) followed by a combination dose expansion.

TrialNet Pathway to Prevention of T1D
Recruiting
Rationale: The accrual of data from the laboratory and from epidemiologic and prevention trials has improved the understanding of the etiology and pathogenesis of type 1 diabetes mellitus (T1DM). Genetic and immunologic factors play a key role in the development of T1DM, and characterization of the early metabolic abnormalities in T1DM is steadily increasing. However, information regarding the natural history of T1DM remains incomplete. The TrialNet Natural History Study of the Development of T... Read More
