This is a single-arm, observational study of HIV-negative MSM with substance use disorder. Those who meet pre-screening criteria will attend a Screening Visit (Visit 1), where the informed consent process will be conducted and study eligibility will be confirmed. Eligible participants will attend three additional visits over the course of the study - the Enrollment Visit (Visit 2), Month 1 Visit (Visit 3), and Month 2 Visit (Visit 4). Participants will take one PrEP digital pill per day, for 60 days total, while using the digital pill system (DPS) and Beiwe, a digital phenotyping app. On nonadherent days, participants will receive brief surveys prompting them to report the reasons for their missed dose, as well as their engagement in substance use and sexual activity. Timeline followback will be conducted at the Month 1 and Month 2 Visits to understand the context of any nonadherence. Qualitative user experience exit interviews and dried blood spots (DBS) will be conducted at the Month 2 Visit. Read Less

Crohn's disease (CD) is a long-lasting disease that causes severe inflammation (redness, swelling), in the digestive tract, most often affecting the bowels. It can cause many different symptoms including abdominal pain, diarrhea, tiredness, and weight loss. This study will assess how safe and effective risankizumab subcutaneous (SC) induction treatment is in treating moderately to severely active CD in adult participants. Risankizumab is an approved drug for adults with CD. This study comprises of a Period A, a Period B, and a Period C. In Period A, participants are placed in 1 of 2 groups to receive either risankizumab SC Dose A or Placebo. In Period B, based on response, participants will receive risankizumab SC Dose B or Placebo. Participants who do not have improvement in CD symptoms at Week 12 will receive risankizumab SC Dose C and participants with worsening CD symptoms in period B will receive risankizumab SC. In Period C, eligible participants will receive open-label risankizumab SC Dose D. Approximately 276 adult participants with a diagnosis of moderately to severely active CD will be enrolled in approximately 250 sites globally. Participants will receive SC induction treatment of risankizumab or matching placebo for up to 24 weeks in Period A and B followed by an open-label risankizumab extension in Period C for 52 weeks. The duration of the study will be approximately 93 weeks. Read Less

The goal of the Dose Escalation phase of the study is to evaluate the safety, tolerability, pharmacokinetics (PK) and preliminary anti-tumor activity to determine the preliminary recommended dose for expansion (RDE) of NKT3964 in adults with advanced or metastatic solid tumors. The goal of the Expansion phase of the study is to evaluate the preliminary anti-tumor activity of NKT3964 at the RDEs based on objective response rate (ORR) and determine the preliminary recommended Phase 2 dose (RP2D).

This study is researching a combination of 2 experimental drugs, referred to as "study drugs", called odronextamab (also known as REGN1979) and cemiplimab (also known as REGN2810). The study is focused on patients who have relapse/refractory aggressive B-cell lymphoma. The aim of the study is to see how safe and tolerable the study drugs are, and to define the recommended dose regimen for the combination with odronextamab. This study is also looking at several other research questions, including: * What side effects may happen from taking the study drugs * How effective the study drugs are against the disease * How much study drug is in the blood at different times * Whether the body makes substances or protein called antibodies against the study drugs (that could make the drugs less effective or could lead to side effects) Read Less

The primary objective of this study is to assess the efficacy of a single dose of ravulizumab IV compared with placebo in reducing the risk of the clinical consequences of AKI (MAKE) at 90 days in adult participants with CKD who undergo non-emergent cardiac surgery with CPB. Read Less

Chronic lymphocytic leukemia (CLL) is the most common leukemia (cancer of blood cells). The purpose of this study is to assess retreatment with venetoclax-obinutuzumab (VenG) in participants previously treated with fixed duration first-line (IL) therapy of venetoclax in combination with an anti-CD20 antibody +/- X (where X is any additional drug). Adverse events and change in disease activity will be assessed. Venetoclax is an approved drug for the treatment of CLL. Study doctors put the participants in 1 of 2 groups, called cohorts, based on when symptoms of CLL came back after previous treatment in first-line. Approximately 75 adult participants with CLL who have been treated with venetoclax in combination with an anti-CD20 antibody +/- X will be enrolled in the study in approximately 60 sites worldwide. Participants will receive intravenous (IV) obinutuzumab + oral venetoclax (VenG) in 28-day cycles for a total of 6 cycles per cohort, followed by 6 to 18 cycles of venetoclax alone, for a total treatment of 12 to 24 cycles, depending on the cohort. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires. Read Less

This is a multicenter, randomized, open-label, Phase 3 study in participants with newly diagnosed multiple myeloma to evaluate the benefits of teclistamab in combination with lenalidomide and teclistamab alone versus lenalidomide alone as maintenance therapy after autologous stem cell transplant.

This prospective longitudinal study will compare incidence rates of Medicare beneficiary surgical and minimally invasive intervention post index procedure, as well as harms associated with the MILD procedure, at 24 months post-treatment with MILD, tested against a control group of similar patients that have had a comparable procedure. This study will start with patients treated with a study procedure having an index date on or after January 1, 2017, and enrollment will continue until stopped by the sponsor. Read Less

This phase III trial investigates the best dose of vinblastine in combination with selumetinib and the benefit of adding vinblastine to selumetinib compared to selumetinib alone in treating children and young adults with low-grade glioma (a common type of brain cancer) that has come back after prior treatment (recurrent) or does not respond to therapy (progressive). Selumetinib is a drug that works by blocking a protein that lets tumor cells grow without stopping. Vinblastine blocks cell growth by stopping cell division and may kill cancer cells. Giving selumetinib in combination with vinblastine may work better than selumetinib alone in treating recurrent or progressive low-grade glioma. Read Less

This phase II trial studies how well osimertinib works in treating patients with non-small cell lung cancer with EGFR exon 20 insertion mutation that is stage IIIB-IV or has come back after a period of improvement (recurrent). Osimertinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Read Less

Background: During the first few decades of life, the brain changes dramatically in shape and function. Sleep lets researchers measure these changes. Researchers want to create a database of sleep and neurodevelopmental data in a group of infants and children to learn more. Objective: To address a knowledge and data gap in the field of sleep and neurodevelopment in infants and children. Eligibility: Children ages 6 months to 76 months who may or may not be at risk for neurodevelopmental and neuropsychiatric disorders. Also, children ages 6 months to 8 years who have a referral for a sleep study. Design: Participants will have neurodevelopmental testing. They will have a medical, psychiatric, and family history. They will have a physical and neurological exam. They will be interviewed and complete surveys. They will give a cheek swab and/or blood sample. Some participants will have 1 study visit that lasts 2 days. Other participants will have up to 4 study visits. Each visit will last 2 days. Visits occur every 8 months to 1 year, for a total participation time of 2 years. Participants will have a 20-minute daytime electroencephalogram (EEG), if possible. This EEG session will be used to calibrate the machine for the overnight study. Participants will take part in an inpatient overnight sleep study. Electrodes will be placed on the participants. For young children, parents will help place the EEG leads. Other sensors may also be placed. A gauze cap will be placed on participants head to protect the leads and keep the participants from moving them. 'Lights out' will occur as close to participants bedtime as possible. Read Less
