The goal of this clinical trial is to learn if DOC1021 + pIFN will be safe and will lead to tumor responses in patients with refractory melanoma. DOC1021 is a dendritic cell immunotherapy derived from a patient's own blood cells and loaded with antigens from the patient's tumor in the form of tumor lysate and mRNA. The goal is to stimulate a T cell immune response that eliminates tumor cells. The study consists of two components: an initial phase I safety study to confirm safety/tolerability of the treatment regimen, and, subsequently, a single-arm phase II cohort to assess efficacy of the treatment regimen. All participants will: - Take filgrastim subcutaneously x 5 doses and subsequently undergo a leukapheresis collection - Receive two doses of DOC1021 under image guidance 2 weeks apart - Receive subcutaneous pIFN injections weekly for a total of 4 doses in parallel with the DOC1021 injections - Undergo an optional image-guided perinodal DOC1021 booster injection approximately 6 months after the first DOC1021 dose along with additional subcutaneous pIFN injections at time of the booster and the subsequent week for a total of 2 pIFN doses - Visit the clinic regularly to assess quality of life, symptoms, medication use, imaging, bloodwork, and to receive optional treatment with anti-PD1 agents

The goal of this clinical trial is to learn whether the study drug THRV-1268 can safely and effectively shorten the QT interval in people diagnosed with Long QT Syndrome Type 2 (LQTS 2). The study will also learn about the safety and tolerability of THRV-1268 at different doses. The main questions this study aims to answer are: Does THRV-1268 reduce the QTc interval (a measure of the heart's electrical recovery time)? What side effects or medical problems occur when participants take THRV-1268? Which dose of THRV-1268 works best and is safest? Participants will: Complete a 3-week observation period with ECG and Holter monitoring to establish baseline QTc measurements Take THRV-1268 tablets twice daily at two dose levels for 6 weeks (Part A) or be randomly assigned to a dose group for 6 weeks (Part B) Have clinic visits and tests to monitor safety and changes in their heart rhythm May continue taking THRV-1268 for up to 1 year for ongoing safety and efficacy evaluation Researchers will compare changes in QTc over time and evaluate side effects to determine whether THRV-1268 can help reduce the risk of abnormal heart rhythms and sudden cardiac events in people with LQTS 2.

This phase II trial compares the use of pembrolizumab and radiation therapy to chemotherapy with cisplatin, gemcitabine, 5-fluorouracil or mitomycin-C and radiation therapy for the treatment of non-muscle invasive bladder 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. Chemotherapy drugs, such as cisplatin, gemcitabine, 5-fluorouracil or mitomycin-C, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Giving pembrolizumab with radiation may kill more tumor cells than chemotherapy with radiation therapy in patients with non-muscle invasive bladder cancer.

This phase II trial compares the effects of immunoglobulin replacement therapy with a placebo for preventing infectious complications in patients receiving CD19 chimeric antigen receptor (CAR)-T cell therapy. Hypogammaglobulinemia is a common complication in patients who receive CD19 CAR-T cell therapy. This is a condition in which the level of immunoglobulins (antibodies) in the blood is low and the risk of infection is high. Immunoglobulin replacement therapy works by replacing the body's immunoglobulin G (IgG) antibodies with donor blood product derived IgG antibodies that may help prevent infection. IgG antibodies are often depleted as a result of CAR-T therapy. Giving immunoglobulin replacement therapy may prevent infectious complications in patients receiving CD19 CAR-T cell therapy.

The goal of this Nutrition for Precision Health (NPH) powered by All of Us research study is to develop Artificial Intelligence/Machine Learning (AI/ML) algorithms that predict individual responses to diet patterns using rich multimodal data streams collected across multiple domains (e.g., behavior, social, environmental, clinical and molecular biomarkers). NPH includes a large phenotyping cohort (Module 1, N=8000) and two separate follow-up groups drawn from a subset of Module 1participants. One group (Module 2, N=1200) receives three distinct diets in a 14-day crossover sequence, with at least a 14-day washout period between diets, while living in their own homes. A second group (Module 3, N=150) receives the same three diets under full-time supervision in a residential research setting. We will train and test AI/ML models to predict 0-4 hour postprandial response curves for glucose, insulin, triglycerides, and GLP-1, to the standardized diet-specific meal test (DSMT) collected after each of the three different diets delivered in Module 2. Each diet functions as a controlled stimulus to reveal biological features (such as individual variables, patterns, or clusters of measurements) that best predict a person's response. The Module 2 DSMT response curves are the primary outcomes (dependent variables) for AI/ML algorithms that predict individual responses to diet patterns. As a secondary objective, NPH will evaluate the validity and acceptability of technology-based dietary assessment tools. The Automated Self-Administered 24-hour recall (ASA24), Automatic Ingestion Monitor-2 (AIM-2), and the mobile food record (mFR) will be evaluated in Modules 2 and 3, and the ASA24 food record and the image-assisted ASA24 recall will be evaluated only in Module 3. Total energy intake, macronutrient and dietary fiber intake data are the main outcomes for validity testing compared against measures of actual intake. Acceptability will be determined from feedback surveys.
