Researchers are studying pulmonary arterial hypertension (PAH), including its common subtypes idiopathic PAH (IPAH) and connective tissue disease-associated PAH (PAH-CTD). The study aims to develop pulmonary vascular biomarker signatures using hyperpolarized 129Xe MRI to differentiate these subtypes and to evaluate the ability of this imaging to monitor disease progression and treatment response over time. Additional assessments such as laboratory tests, echocardiography, and six-minute walk distance (6MWD) are also used to support these evaluations. The study is observational and enrolls 20 subjects divided into two groups: 10 with IPAH and 10 with PAH-CTD. Participants will undergo hyperpolarized 129Xe MRI and MR spectroscopy at baseline, 3 months, 6 months, and 12 months. Alongside imaging, data from standard clinical assessments including labs, echocardiography, and 6MWD will be collected at these same timepoints to track changes. Participants will be monitored for changes in pulmonary vascular remodeling, red blood cell oscillation amplitude, 6MWD, NTproBNP levels, and WHO functional class over one year. Safety is assessed by tracking adverse events, serious adverse events, withdrawals, and specific examinations such as electrocardiograms and vital signs. The total follow-up period for each participant is one year, with multiple scheduled evaluations to comprehensively assess disease status and response.

Researchers are investigating the specific targets of T cells involved in autoimmune diseases by studying tissues from patients with active organ inflammation caused by autoimmune conditions. The study aims to identify which T cells are activated and expanding in diseased tissues compared to blood or normal tissues. This information will help discover new peptide targets and their associated T cell receptors (TCRs) to develop potential new therapies for autoimmune diseases. Participants will provide tissue samples and matched blood samples during clinical procedures such as endoscopy, arthrocentesis, lumbar puncture, skin biopsy, bronchoscopy, or surgery, depending on their autoimmune condition. The study includes several groups covering diseases like Crohn's disease, ulcerative colitis, celiac disease, ankylosing spondylitis, multiple sclerosis, scleroderma, systemic sclerosis, and other autoimmune diseases. Samples may come from excess clinical materials or research-specific biopsies, with the possibility of serial sampling over time. During the study, participants will undergo standard clinical procedures with collection of additional tissue or fluid samples and companion blood draws. Researchers will analyze these samples to identify peptide targets linked to disease-reactive T cells over a period of up to three years. The study includes comprehensive assessments of tissues and blood to understand T cell activity in autoimmune disorders, with monitoring of participant safety and no interventions beyond routine clinical care.

Researchers are evaluating the safety and effectiveness of anti-CD19 CAR NK cells (KN5501) in patients with relapsed or refractory B-cell related autoimmune diseases. This early phase 1 pilot study plans to enroll 15 patients to assess the treatment's safety, feasibility, and effectiveness. The study also explores how well KN5501 expands, persists, and depletes CD19 positive B cells in these patients. Participants will receive a preparatory treatment with Fludarabine and Cyclophosphamide on three days before the infusion of anti-CD19 CAR NK cells. The trial includes two dose levels (6x10^9 and 9x10^9 cells) for dose escalation. This is a single-arm, open-label study without a placebo group. During the study, researchers will monitor participants closely for dose limiting toxicities and adverse events within the first 4 weeks and at 12, 24, 36, and 52 weeks after infusion. Effectiveness will be evaluated by disease control and remission rates at the same time points. Participants will undergo regular assessments including clinical evaluations and laboratory tests, with follow-up lasting up to one year after treatment.

Researchers are evaluating an open-label, dose escalation study for patients with relapsed and refractory autoimmune diseases. The study focuses on a therapeutic biological product called TI-0032-III injection, which uses lipid nanoparticles to deliver circular RNA encoding the CD19 chimeric antigen receptor (CAR) targeting T cells. This treatment is intended for various difficult-to-treat B cell-related autoimmune diseases, including systemic lupus erythematosus, Sjögren's syndrome, systemic sclerosis, idiopathic inflammatory myositis, and antiphospholipid syndrome. Participants will receive multiple doses of TI-0032-III injection infused into the body. This in vivo CD19-targeted CAR T cell therapy is being studied for safety and efficacy, with treatment delivered over a period involving dose escalation. The trial is an interventional Phase 1 study where the investigational injection is the main intervention. During the study, participants will be monitored for safety outcomes from the first dose up to 12 months. Researchers will also assess efficacy outcomes for the different autoimmune diseases up to 3 months after the first dose. Evaluations include clinical assessments and laboratory tests to measure treatment impact and safety. The total participant involvement will span at least one year to observe safety and disease response.

This research focuses on people who have previously been treated with KYV-101, an autologous CAR T cell therapy, to monitor long-term safety and persistence of the treatment. It aims to collect information about delayed side effects and ongoing presence of the gene-modified cells in participants who received at least one infusion of KYV-101 in earlier clinical trials sponsored by Kyverna Therapeutics. Participants in this observational study will continue to be followed for up to 15 years after their initial KYV-101 treatment. The study will track various health outcomes including treatment-related adverse events, new or returning malignancies, neurological and autoimmune conditions, blood disorders, infections, and specific laboratory tests related to the therapy. For some participants with certain conditions, additional measures like medication use and functional assessments will be monitored for shorter periods. Throughout the study, participants will undergo regular health evaluations, lab tests, and questionnaires to assess the long-term effects of KYV-101. Researchers will collect data on safety events and laboratory markers up to 15 years, with some specific tests monitored up to 5 years. The overall goal is to better understand the long-term impact and safety profile of the gene-modified therapy in people treated previously.

Researchers are studying the use of unlicensed cryopreserved cord blood units (CBUs) for transplantation in both pediatric and adult patients with various blood-related cancers and other disorders affecting the blood-forming system. This observational study aims to evaluate outcomes such as the recovery of a certain level of white blood cells after transplantation, as well as the incidence of infections, infusion reactions, survival rates, and graft-versus-host disease over time. The study involves patients receiving unlicensed CBUs at multiple U.S. transplant centers. These CBUs are used for patients with hematologic malignancies and other blood disorders. The protocol collects data on patients who receive these unlicensed transplant units, without administering a new treatment but observing the outcomes after transplantation. Participants will be monitored for neutrophil recovery at 60 and 100 days post-transplant, along with assessments of infection transmission, infusion reactions, survival one year after transplant, and occurrences of acute and chronic graft-versus-host disease. Platelet engraftment levels will also be tracked. The study includes patients of any age and follows them through the transplantation and recovery process to gather information on these key outcomes.
