Transplants clinical trials at UCLA

Primary Objectives: - Cohort A: To evaluate the efficacy of BIVV020 in prevention of AMR - Cohort B: To evaluate the efficacy of BIVV020 in treatment of active AMR Secondary Objectives: - To assess the overall efficacy of BIVV020 in prevention or treatment of AMR - To characterize the safety and tolerability of BIVV020 in kidney transplant participants - To characterize the pharmacokinetic (PK) profile of BIVV020 in kidney transplant participants - To evaluate the immunogenicity of BIVV020

This study seeks to determine if administration of the drug belumosudil (KD025) will be safe and improve transplant tolerance in subjects undergoing combined Human Leukocyte Antigen (HLA) single haplotype-matched related or 0-3 antigen (at A, B, C, DR) HLA mismatched unrelated living donor kidney and hematopoietic stem cell transplantation.

This study will evaluate the safety and efficacy of AT-1501 compared with tacrolimus in patients undergoing kidney transplantation.

The purpose of this study is to evaluate the safety, tolerability, and efficacy of AntiBKV in reducing BKV DNAemia and progression to biopsy-confirmed BKVAN in Kidney Transplant Recipients (KTRs). The study includes two parts. The phase II part will evaluate the safety of AntiBKV in KTRs and establish proof of concept. The phase III part will assess the efficacy of AntiBKV in KTRs. For both the phase II and phase III parts, participants will be randomized to receive either four doses of AntiBKV or four doses of placebo (every 4 weeks). Both the phase II and phase III parts will follow identical study assessments and schedules for participants. Based on an interim analysis after phase II total sample size for the trial will be defined. Eligible participants will receive an intravenous infusion of the investigational medicinal product (IMP) that will be administered four times at a 4-week interval. Seven days following the first IMP administration, participants will be re-evaluated for BKV DNAemia and, if appropriate, changes of immunosuppressive treatment will be started. After administration of the final dose, participants will return as out participants for periodic safety, BKV DNAemia, and PK follow-up assessments until the end of the trial visits, 26 weeks post last IMP application. Regular kidney biopsies will be performed at baseline (prior to infusion) and on Day 141 (8 weeks after full dosing). An additional biopsy will be taken on Day 267 (optional) and as clinically indicated.

The purpose of this study is to find out if an investigational treatment will allow kidney transplant recipients to better accept their new kidney and stop immunosuppressive medicines. This study is for kidney transplant recipients who receive a kidney from a sibling donor. The investigational treatment is started after kidney transplant. It begins with a regimen of a drug called rabbit anti-thymocyte globulin (rATG) combined with radiation therapy (known as total lymphoid irradiation, or TLI) to the lymph nodes and spleen. This is followed by an infusion of blood stem cells, which will be donated by the same sibling who donated their kidney. Researchers think that this treatment allows immune cells from the donor and recipient to live side by side, a condition referred to as "mixed chimerism." Mixed chimerism may help create a state of "tolerance" in kidney transplant recipients in which all immunosuppressive medications can be stopped without rejection of the transplanted kidney. This study will test whether (1) the investigational treatment will allow patients to stop immunosuppressive medications after their kidney transplant and (2) if the treatment impacts the rate of kidney rejection and the side effects of immunosuppressive medications.

The goal of this clinical trial is to compare ARINA-1 plus Standard of Care vs Standard of Care alone. The main question it aims to answer are: - Evaluate the effectiveness of ARINA-1 in preventing bronchiolitis obliterans syndrome (BOS) progression in participants with a bilateral lung transplant - To evaluate the effectiveness of ARINA-1 on improving quality of life decline and preventing or delaying the use of augmented immunosuppression in participants with pre-BOS relative to SOC. Participants will have clinic visits at screening, randomization (day 1) and weeks 4, 12, 18, and 24. After week 24, participants will have clinic visits at weeks 32, 40, and 48. Participants will also have a telehealth visit on day 2 and phone calls to assess adverse events (AEs), serious adverse events (SAEs), and review patient education will occur during weeks 5, 8, 36, and 44.

The primary outcome of this study is dysphagia (difficulty swallowing) on postoperative speech and swallow evaluation following lung transplantation. Transesophageal echocardiography (TEE) (creates pictures of the heart from inside the participants body) is routinely performed for all lung transplantations at the University of California, Los Angeles (UCLA) and it is the standard of care. Patients are randomized to two groups. The intervention group would limit the number of TEE clips (# pictures taken) per case. The control group would leave the number of TEE clips to the discretion of the attending anesthesiologist. The investigators hypothesize that reduction in TEE imaging during lung transplantation will reduce dysphagia.

The ProActive registry is a longitudinal, multi-center study with a prospective arm observing clinical care for patients receiving physician ordered Prospera, an allograft rejection test, and a historical control arm collecting data on cases at the same sites whose kidney allograft rejection status was managed with Serum Creatinine SCr/estimated Glomerular Filtration Rate eGFR. This registry will compare patient management and outcomes in patients who receive Prospera (Prospera arm) to the outcomes of the historical control group (control arm) to determine Prospera's clinical utility. High-risk subjects defined as having a biopsy-demonstrated rejection event or at least one pre-existing Donor Specific Antibody DSA with total Mean Fluorescent Intensity MFI>3000 or a calculated Panel Reactive Antibodies cPRA>70% will be followed for an additional period up to 24 months in both the Prospera arm and historical control arm.

This is a prospective, multi-center, observational study. Subjects will have OmniGraf™ (TruGraf® and TRAC™) testing at study enrollment and thereafter every 3 months. In addition subjects will have OmniGraf™ (TruGraf® and TRAC™) testing at any time there is a clinical suspicion of acute rejection. Data collection for the primary objective extends over a 2-year period.
