This is a phase 3 study to evaluate effects on proteinuria and glomerular filtration rate of sibeprenlimab 400 mg subcutaneously (s.c.) Q 4 weeks in adults with IgAN who are receiving maximally tolerated standard-of-care therapy.

The purpose of this study is to assess the safety and efficacy (including durability) of up to 2 REACT injections given 3 months (+30 days) apart and delivered percutaneously into biopsied and non-biopsied contralateral kidneys in participants with T2DM and CKD.

This is a Phase 2, multicenter, open-label, randomized, controlled study designed to evaluate the safety and efficacy of pegcetacoplan in patients who have post-transplant recurrence of C3G or IC-MPGN.

This clinical study is evaluating a drug called BT7480 alone and in combination with nivolumab in participants with advanced solid tumors associated with Nectin-4 expression.

The main goals of the study are to:

* Find the recommended dose of BT7480 that can be given safely to participants alone and in combination with nivolumab
* Learn about the side effects and effectiveness of BT7480 alone and in combination with nivolumab
* Learn about the effect BT7480 has on the body and how BT7480 is cleared by the body
* Learn about the side effects and effectiveness of BT7480 in patients with reduced kidney function

The Primary Completion Date and Study Completion Date have been updated to reflect completion of the adolescent cohort, which has been added to the protocol.

The study is designed as a multicenter, randomized, double-blind, parallel group, placebo-controlled study to evaluate the efficacy and safety of iptacopan (LNP023) in complement 3 glomerulopathy.

The overarching hypothesis is that CF carriers are at increased risk for developing most of the extrapulmonary conditions associated with CF compared to the general population. Specifically, it is hypothesized that this pilot data will detect subclinical evidence of pancreatic and kidney disorders among CF carriers. This will be determined by bringing CF carriers and controls to the CRU for one visit where they will answer survey questions and undergo laboratory testing. Additionally, they will collect urine and stool samples at home that will be sent to outside laboratories for testing.

This phase II trial studies how well combination chemotherapy works in treating patients with newly diagnosed stage II-IV diffuse anaplastic Wilms tumors (DAWT) or favorable histology Wilms tumors (FHWT) that have come back (relapsed). Drugs used in chemotherapy regimens such as UH-3 (vincristine, doxorubicin, cyclophosphamide, carboplatin, etoposide, and irinotecan) and ICE/Cyclo/Topo (ifosfamide, carboplatin, etoposide, cyclophosphamide, and topotecan) 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. This trial may help doctors find out what effects, good and/or bad, regimen UH-3 has on patients with newly diagnosed DAWT and standard risk relapsed FHWT (those treated with only 2 drugs for the initial WT) and regimen ICE/Cyclo/Topo has on patients with high and very high risk relapsed FHWT (those treated with 3 or more drugs for the initial WT).

This research trial studies kidney tumors in younger patients. Collecting and storing samples of tumor tissue, blood, and urine from patients with cancer to study in the laboratory may help doctors learn more about changes that occur in deoxyribonucleic acid (DNA) and identify biomarkers related to cancer.

This is a pilot/feasibility, multicenter, randomized, open label, clinical trial to test that hypothesis that plasmapheresis plus rituximab prior to or at the time of kidney transplantation can prevent recurrent FSGS in children and adults.

Tranexamic acid and placebo will be given during surgery to patients who have elected to undergo lumber interbody fusion on 2 or more levels. Information regarding blood loss, transfusions needed, postoperative cognitive status (including delirium), postoperative markers of systemic inflammation and duration of hospital stay will be collected.
