In this study, researchers will learn more about the use of felzartamab in participants with immunoglobulin A nephropathy (IgAN). IgAN is a kidney disease caused by the buildup of an antibody called IgA in the kidneys over time. In people with IgAN, abnormal IgA and other antibodies form clusters that build up in the small filters of the kidneys, which leads to inflammation and damage. Felzartamab is designed to target certain immune cells that produce these abnormal antibodies. This study will focus on participants who have protein in their urine (proteinuria) as a result of damaged kidneys. The main goal of the study is to learn about the effect felzartamab has on proteinuria. The main question that researchers want to answer is: • How much does the amount of protein in the urine change from the start of the study to Week 36? Researchers will learn about the effect felzartamab has on the kidneys' ability to filter blood. They will also learn more about the safety of felzartamab and how it is processed by the body. The study will be done as follows: - Participants will be screened to check if they can join the study. - Participants will be randomized to receive either felzartamab or a placebo. A placebo looks like the study drug but contains no real medicine. - Neither the researchers nor the participants will know what the participants will receive. - Participants will receive felzartamab or placebo as intravenous (IV) infusions. The treatment period will last 24 weeks. - Afterwards, participants will enter a follow-up period which will last 80 weeks. - In total, participants will have 17 study visits. Participants will stay in the study for about 2 years.

The objective of this study protocol is to test whether intermittent theta-burst transcranial magnetic stimulation (iTBS-TMS) to the inferior parietal lobule (IPL) can strengthen functional connectivity with a key region in emotion regulation (ER) neurocircuitry (anterior insula, AI) and improve performance on ER-related tasks in patients with bipolar disorder. Individual IPL sites for stimulation will be identified through baseline, pre-TMS functional magnetic resonance imaging (fMRI) scans. Patient-specific IPL subregions showing positive functional connectivity with the anterior insula and falling within the patient-specific frontoparietal control network will be used as individualized target sites for TMS stimulation. Patients will be randomized to receive 24 sessions of active versus sham iTBS to patient-specific IPL targets (6 sessions/day, 4 days, 43,200 pulses total). Post-iTBS resting-state and task-based fMRI scans will be acquired 3 days after the final day of iTBS administration (Day 4) following identical procedures as baseline. Effects of iTBS-TMS on ER will be evaluated by comparing pre-TMS versus post-TMS functional connectivity and behavior during performance on ER tasks.

The goal of this clinical trial is to learn how the pupil responds to different light stimuli and how that relates to sleep and daily rhythms in healthy people of different ages. The main questions it aims to answer are: - Does the eye's pupil response to light stimuli differ by the sex and age of the participant? - Is the eye's pupil response to light stimuli related to each participant's sleep timing, their body clock timing, and their hormone responses to light. Participants will have a special eye exam and complete questionnaires before starting the study to see if they can participate. If they can participate, they will wear a special watch that monitors their activity and light levels for one week. Then they will live in a research room at the Mass General Hospital for 3 days/2 nights during which we will test their pupil response to light, their body clock timing, and their hormone responses to light.

The purpose of this clinical trial is to learn the safety and effects of the study medicine (PF-07799544) alone or in combination as a potential cancer treatment for adults with advanced solid tumors. The study will be conducted in two parts: PF-07799544 as a single agent (Phase 1a) and PF-07799544 in combination with another study medicine called PF-07799933 (Phase 1b). Phase 1a is no longer open for enrollment. In Phase1b (noted as "this study"), we are seeking participants who have: - a solid tumor which is metastatic or recurrent (excluding colorectal cancer) - tumor with the mutation (abnormal gene) called "BRAF V600" - received required prior treatment for cancer per cohort assigned. All participants in this study will receive both study medicines. Both study medicines are tablets that are taken by mouth at home twice a day. Participants will receive study medicines until their cancer is no longer responding, unacceptable side effects, or 2 years. Participants may continue to receive study therapy beyond 2 years. We will examine the experiences of people receiving the study medicines. This will help us determine if the study medicines are safe and effective.

This is a Phase Ib/II, open-label, multicenter, randomized umbrella study in participants with breast cancer. The study is designed with the flexibility to open new treatment arms as new treatments become available, close existing treatment arms that demonstrate minimal clinical activity or unacceptable toxicity, or modify the patient population. Cohort 1 will focus on participants with inoperable, locally advanced or metastatic, estrogen receptor-positive (ER+), HER2-negative breast cancer who had disease progression during or following treatment with a cyclin-dependent kinase 4/6 inhibitor (CDK4/6i; e.g., palbociclib, ribociclib, abemaciclib) in the first- or second-line setting. Cohort 2 will focus on inoperable, locally advanced or metastatic, ER+, HER2-positive breast cancer with previous progression to standard-of-care anti-HER2 therapies, of which one was a trastuzumab-and-taxane-based systemic therapy (including in the early setting if recurrence occurred within 6 months of finishing adjuvant therapy) and one was a HER2-targeting antibody-drug conjugate (ADC; e.g., ado-trastuzumab emtansine or trastuzumab-deruxtecan) or a HER2-targeting tyrosine kinase inhibitor (TKI; e.g., tucatinib, lapatinib, pyrotinib, or neratinib). Cohort 3 will focus on inoperable, locally advanced or metastatic, ER+, HER2-negative, PIK3CA-mutated breast cancer with resistance to adjuvant endocrine therapy.

Without an explanation for severe and sometimes life-threatening symptoms, patients and their families are left in a state of unknown. Many individuals find themselves being passed from physician to physician, undergoing countless and often repetitive tests in the hopes of finding answers and insight about what the future may hold. This long and arduous journey to find a diagnosis does not end for many patients- the Office of Rare Diseases Research (ORDR) notes that 6% of individuals seeking their assistance have an undiagnosed disorder. In 2008, the National Institutes of Health (NIH) Undiagnosed Diseases Program (UDP) was established with the goal of providing care and answers for these individuals with mysterious conditions who have long eluded diagnosis. The NIH UDP is a joint venture of the NIH ORDR, the National Human Genome Research Institute Intramural Research Program (NHGRI-IRP), and the NIH Clinical Research Center (CRC) (1-3). The goals of the NIH UDP are to: (1) provide answers for patients with undiagnosed diseases; (2) generate new knowledge about disease mechanisms; (3) assess the application of new approaches to phenotyping and the use of genomic technologies; and (4) identify potential therapeutic targets, if possible. To date, the UDP has evaluated 3300 medical records and admitted 750 individuals with rare and undiagnosed conditions to the NIH Clinical Center. The NIH UDP has identified more than 70 rare disease diagnoses and several new conditions. The success of the NIH UDP prompted the NIH Common Fund to support the establishment of a network of medical research centers, the Undiagnosed Diseases Network (UDN), for fiscal years 2013-2020. The clinical sites will perform extensive phenotyping, genetic analyses, and functional studies of potential disease-causing variants. The testing performed on patients involves medically indicated studies intended to help reach a diagnosis, as well as research investigations that include a skin biopsy, blood draws, and DNA analysis. In addition, the UDN will further the goals of the UDP by permitting the sharing of personally identifiable phenotypic and genotypic information within the network. By sharing participant information and encouraging collaboration, the UDN hopes to improve the understanding of rare conditions and advance the diagnostic process and care for individuals with undiagnosed diseases....

This phase III trial compares the effect of immunotherapy (IO) with stereotactic body radiation therapy (SBRT) to IO alone in treating patients with liver cancer (hepatocellular cancer) that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). The usual approach is treatment with IO-based drug combinations, such as atezolizumab and bevacizumab, durvalumab and tremelimumab, or ipilimumab and nivolumab. IO with monoclonal antibodies, such as durvalumab, tremelimumab, atezolizumab, nivolumab and ipilimumab, may help the body's immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. Bevacizumab is in a class of medications called antiangiogenic agents. It works by stopping the formation of blood vessels that bring oxygen and nutrients to tumor. This may slow the growth and spread of tumor cells. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. SBRT is a type of external radiation therapy that uses special equipment to position a patient and precisely deliver radiation to tumors in the body (except the brain). The total dose of radiation is divided into smaller doses given over several days. This type of radiation therapy helps spare normal tissue. Giving IO with SBRT may be more effective than IO alone in helping patients with advanced hepatocellular cancer live longer.
