ABBV-RGX-314 (also known as RGX-314) is being developed as a novel one-time gene therapy for the treatment of neovascular (wet) age-related macular degeneration (wet AMD). Wet AMD is characterized by loss of vision due to new, leaky blood vessel formation in the retina. Wet AMD is a significant cause of vision loss in the United States, Europe and Japan, with up to 2 million people living with wet AMD in these geographies alone. Current anti-vascular endothelial growth factor (VEGF) therapies have significantly changed the landscape for treatment of wet AMD, becoming the standard of care due to their ability to prevent progression of vision loss in the majority of patients. These therapies, however, require life-long intraocular injections, typically repeated every four to 12 weeks in frequency, to maintain efficacy. Due to the burden of treatment, patients often experience a decline in vision with reduced frequency of treatment over time. ABBV-RGX-314 is being developed as a potential one-time treatment for wet AMD. Read Less

Hydrocephalus is a potentially debilitating neurological condition that primarily affects babies under a year of age and has traditionally been treated by inserting a shunt between the brain and the abdomen. A newer endoscopic procedure offers hope of shunt- free treatment that may reduce complications over a child's life, but it is not clear if the endoscopic procedure results in similar intellectual outcome as shunt. Therefore, the investigators propose a randomized trial to compare intellectual outcome and brain structural integrity between these two treatments, to help families make the best treatment decision for their baby.

Background: Some children/adolescents who have had a stem cell transplant live with chronic graft-versus-host-disease (cGVHD). cGVHD is a side effect of the transplant that can cause multiple bothersome symptoms and negatively affect a child/adolescent squality of daily life. The questionnaires that measure thesymptoms caused by cGVHD are designed for adults. Children/adolescents may not describe their symptoms in the same way. The goal of this research is to improve the way we measure how bothersome these symptoms are for children/adolescents living with cGVHD. Objective: To develop a questionnaire (The Pediatric cGHVD Symptom Scale) for children/adolescents living with cGVHD to identify the symptoms they are experiencing and describe how bothersome those symptoms are to them. An additional goal is to design a parent/guardian companion questionnaire that can be used to capture the symptom experiences of very young children who may not be able to complete a questionnaire. Eligibility: Children/adolescents ages 5-17 who are receiving treatment for cGVHD after a stem cell transplant, and their parent/guardian.. Design: This study consists of 2 projects. Children/adolescents with cGVHD and their parent/guardianparticipants will be grouped by the child/adolescent s age: 5-7, 8-12, and 13-17. In project 1, participants will complete an age-appropriate questionnaire about cGVHD symptoms. The questionnaire will ask about the child/adolescent s physical functioning and emotional well-being. The parent/guardian will out fill out a companion questionnaire online. The child/adolescent will then review their completed questionnaire during an interview with a researcher and will be asked whether the questions about their symptoms were difficult to understand. The parent/guardian and child/adolescent will then be interviewed together to further explore their responses to the questionnaires. Interviews will be done in person, by phone, and online. . Based on what is learned through these interviews, the wording of the questionnaire will be improved for better comprehension and ease of response. In project 2, participants will complete this revised questionnairefor their age group along with some other questionnaires that ask about quality of life. Both the child/adolescent and parent/guardian will fill out the questionnaires online at three separate time points. In both projects, children/adolescents with cGVHD and their parent/guardian participants will be grouped by the child/adolescent s age: 5-7, 8-12, and 13-17. ... Read Less

This study is to assess the effectiveness and safety of pacritinib in patients with VEXAS (i.e., Vacuoles in myeloid progenitors, E1 ubiquitin-activating enzyme, X-linked, autoinflammatory manifestations, and somatic) syndrome. 78 patients will be enrolled, randomized to either pacritinib dose A, pacritinib dose B + placebo, or placebo. Randomization will be stratified by prescribed GC dose on the day of randomization. Read Less

The objective of this study is to investigate the safety, tolerability and preliminary activity of ivosidenib in combination with durvalumab and gemcitabine/cisplatin as first-line therapy in participants with locally advanced, unresectable or metastatic cholangiocarcinoma with an IDH1 mutation. The study will begin with a safety lead-in phase (Phase 1b study) to determine the recommended combination dose (RDC) and then will transition to an expansion phase (Phase 2 study) to assess the clinical activity of ivosidenib in combination with durvalumab and gemcitabine/cisplatin at the RCD. During the treatment period participants will have study visits on days 1, 8, and 15 of Cycle 1, on days 1 and 8 of Cycle 2 to 8, and on day 1 of each additional cycle. Cycles 1 through 8 are 21 day cycles, and each following cycle is 28 days. Approximately 30 days and 90 days after treatment has ended, safety follow-up visits will occur and then participants will be followed for survival every 3 months. Study visits may include blood tests, ECG, vital signs, and a physical examination. Read Less

The study will assess the efficacy and safety of pegozafermin administered in participants with compensated cirrhosis due to MASH (biopsy-confirmed fibrosis stage F4 MASH \[previously known as nonalcoholic steatohepatitis, NASH\]). Read Less

This study will evaluate the efficacy and safety of Armour Thyroid treatment compared with synthetic T4 in subjects who have primary hypothyroidism and are currently stabilized (i.e., in-range thyroid-stimulating hormone \[TSH\]) on synthetic T4 treatment. This study will also therefore evaluate the efficacy and safety of dose conversion from synthetic T4 therapy to Armour Thyroid therapy. Read Less

Given the number of anticipated durvalumab-based treatment launches in the hepatobiliary cancer space over the next 3 years, there is a need to capture contemporary real-world data across these indications. LIVER-R is a multicountry, multicenter, observational study of patients with a confirmed diagnosis of hepatobiliary cancer treated with a durvalumab-based regimen as part of routine clinical practice or early access program (EAP). The study design will include primary and secondary data collection. The primary objective of this study is to evaluate the effectiveness of durvalumab-based regimens in real-world settings as measured by real-world overall survival. Other endpoints include demographics, clinical characteristics, clinically significant events of interest, treatment patterns, concomitant medications, and other real-world clinical endpoints (such as duration of treatment, progression-free survival, time to treatment progression, time to next treatment, recurrence-free survival, and time to treatment recurrence).

This randomized phase II trial studies how well obinutuzumab works as maintenance treatment in patients with central nervous system lymphoma who have achieved the disappearance of all signs of cancer in response to treatment (complete response) or a decrease in the size of a tumor, or in the extent of cancer in the body, in response to treatment (partial response). Immunotherapy with obinutuzumab, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Read Less

The primary purpose of the study is to understand how well the study drug can eliminate abnormal plasma cells and laboratory signs of high-risk monoclonal gammopathy of undetermined significance (HR-MGUS) and non high-risk smoldering multiple myeloma (NHR-SMM). This requires understanding the safety and tolerability of the study drug (how the body reacts to linvoseltamab) as well as the effectiveness of the study drug (how well linvoseltamab eliminates plasma cells). All participants will start treatment with gradually increasing doses of linvoseltamab (step-up doses) before they start receiving the assigned full dose. The study is split into 2 parts: * In Part 1, separate groups of 3-6 patients will receive different full doses of linvoseltamab to evaluate the short-term side effects (safety) and tolerability of the study drug within the first 5 weeks after starting treatment. The data collected will help to make a decision about the dosing regimens chosen for Part 2. * In Part 2, a larger number of participants will be randomized to different dosing regimens to further assess the side effects of linvoseltamab, and to evaluate the ability of linvoseltamab to eliminate abnormal plasma cells in HR-MGUS and NHR-SMM. The study is looking at several other research questions, including: * How many participants treated with linvoseltamab have improvement of their HR-MGUS or NHR-SMM? * What side effects may happen from taking the study drug? * How much study drug is in the blood at different times? * Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects).
