In this study, researchers will learn more about a drug called felzartamab in people who have received a kidney transplant and later developed a condition called microvascular inflammation (MVI). MVI is a type of injury to small blood vessels in the transplanted kidney and may be a sign of rejection by the body. It can lead to serious kidney problems over time. In many cases, MVI is caused by antibodies that attack the transplanted kidney. But in some people, MVI happens without these antibodies. This type of MVI is called isolated MVI. There are currently no approved treatments for isolated MVI. The main goal of the study is to learn about the effect felzartamab has on inflammation in the transplanted kidney. The main question researchers want to answer is: • How many participants have no signs of active inflammation in the transplanted kidney after 24 weeks of treatment with felzartamab? Researchers will also study how felzartamab affects kidney function, immune activity, and overall health. They will monitor safety through kidney biopsies, lab tests, and by recording adverse events throughout the study. Adverse events are health problems that may or may not be caused by the study drug. The study will be done in 2 parts as follows: - Participants will be randomly assigned to receive either felzartamab or a placebo. A placebo looks like the study drug but contains no real medicine. - In Part A, participants will receive their assigned drug for 24 weeks. Neither the researchers nor the participants will know who is receiving felzartamab or placebo. - Part B will last another 28 weeks. All participants will receive felzartamab and both participants and researchers will know this. - All treatments will be given by intravenous (IV) infusion at the study site. - Participants will have kidney biopsies at the start of the study, at Week 24, and at Week 52 to help measure changes in inflammation. - Participants will stay in the study for about 1 year.

This phase III trial compares the effect of adding tivozanib to standard therapy pembrolizumab versus pembrolizumab alone for the treatment of patients with high-risk renal cell carcinoma (RCC). 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. Tivozanib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals tumor cells to multiply. This helps stop the spread of tumor cells. Giving pembrolizumab and tivozanib together may work better than pembrolizumab alone in treating patients with RCC.

open study

This phase III trial tests whether continuous or intermittent zanubrutinib after achieving a complete remission (CR) with rituximab works in older adult patients with mantle cell lymphoma (MCL) who have not received treatment in the past (previously untreated). Rituximab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Zanubrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. When zanubrutinib is used in MCL, the current standard of care is to continue administering the drug indefinitely until disease progression. This continuous treatment comes with clinical as well as financial toxicity, which could be especially detrimental in older patients. For patients who achieve a CR after initial zanubrutinib plus rituximab therapy, it may be safe and equally effective to stop treatment and restart zanubrutinib upon disease progression rather than continuing indefinitely in previously untreated older adult patients with MCL.

Background: -Patients who are being evaluated and/or treated at the NIH Clinical Center and adult patients at participating sites will be entered onto this tissue procurement protocol for collection of tissue specimens. Objectives: - To obtain samples from adult and pediatric patients for research purposes from tests and procedures that are done as required by the primary research protocol(s) to which a patient is enrolled or as part of their standard-of-care treatment. - To obtain samples for research purposes from non-surgical procedures, such as percutaneous biopsies, performed for the sole purpose of obtaining tissue specimens or biological fluids for this protocol. Eligibility: -Adult patients (18 years of age and older) and pediatric patients (younger than 18 years of age) who are being evaluated for and/or treated for cancer at the NIH Clinical Center participating sites. Design: - This is a multicenter tissue procurement protocol with NCI as the coordinating center. - For adult patients: specimens for research purposes, as outlined in this protocol, will be obtained from tests and procedures that are done as required by the primary research protocols to which a patient is enrolled or as part of their standard-of-care treatment. Non-surgical procedures, such as percutaneous biopsies, may also be performed for the sole purpose of obtaining tissue specimens or biological fluids for this protocol. Tissues and biological fluids to be procured may include but are not limited to blood, serum, urine, tumor tissue, normal tissue, pleural fluid, CSF, saliva, bronchial alveolar lavage (BAL), circulating tumor cells, hair follicles, and bone marrow. These specimens will be stored with unique identifiers and used to perform only those research studies that are outlined in this protocol. - For pediatric patients: tumor biopsy/resection tissue used for pediatric preclinical model development will only be from tissue already being obtained as part of a procedure necessary for the patient s clinical care or as part of a primary research protocol; blood specimens will be collected as part of a blood collection already scheduled for the patient s clinical care or as part of the planned pre-procedure bloodwork; volumes collected will not exceed institutional research limits. - Given the risks associated with any invasive procedure, such as tumor biopsy, the procedure will be discussed in detail with the patients and their parents/guardian (as indicated), including the side effects, prior to obtaining a separate consent for each procedure. A separate consent will not be signed prior to obtaining samples by minimally invasive measures, such as venipuncture. - This study has two separate consent forms at the NIH Clinical Center: one for adult patients to donate specimens for ongoing research on assay development and studies of molecular pathways, and one for adult and age-appropriate pediatric patients to donate samples for the generation of preclinical models. The study also has consent form templates for adult and pediatric patients at participating sites to donate specimens to create preclinical models. - Patients may remain on study for the duration of their consent or completion of the planned procedure, whichever comes first.

The goal of this study is to evaluate the feasibility and preliminary efficacy of an artificial intelligence (AI)-generated personalized question prompt list (a list of suggested questions to ask during outpatient appointments) for patients with hematologic cancers. The intervention will involve tailoring a standardized prompt to patients' individual characteristics and concerns. This prompt will then be used to ask Washington University's (WashU) HIPAA compliant ChatGPT to generate personalized question lists for outpatient appointments. Analyses will assess the impact of personalized QPLs on patients' question-asking behavior; communicative self-efficacy; and self-reported amount and satisfaction with information obtained about their disease and its treatment. Sub-analyses will explore patterns in questions generated by WashU ChatGPT. Patients will also provide feedback pertaining to the perceived helpfulness and ease-of-use of WashU-ChatGPT-generated question lists, as well as their attitudes and intentions regarding use of AI chatbots and whether they would engage in pre-appointment AI-assisted question brainstorming independently in the future.

Mild cognitive decline is common in early Parkinson disease (PD) and is associated with disability, reduced quality of life (QOL), and increased risk for dementia. Medical treatments for PD do not prevent or treat cognitive decline and may even exacerbate the problem. Unfortunately, existing cognitive interventions for PD, which focus on restoring deficient cognitive skills through cognitive training (repetitive practice of tasks that challenge specific cognitive skills), provide limited benefit for daily function and QOL. To overcome this limitation, the investigators use strategy training. the investigators help people develop targeted strategies to use in everyday life to circumvent cognitive deficits and accomplish daily activities. Contemporary cognitive rehabilitation evidence supports strategy training for other neurological conditions and mild cognitive impairment (MCI), but it has not been well-studied in PD. By teaching strategies for everyday cognition, the investigators hypothesize that our interventions will improve functional outcomes for people with PD. Study participants will complete a baseline cognitive testing session, 10 cognitive treatment sessions with a trained occupational therapist, then have follow-up visits with the study team at 1-week, 3-months, 6-months, and 12-months after completing the study intervention.
