This phase III trial studies whether adding apalutamide to the usual treatment improves outcome in patients with lymph node positive prostate cancer after surgery. Radiation therapy uses high energy x-ray to kill tumor cells and shrink tumors. Androgens, or male sex hormones, can cause the growth of prostate cancer cells. Drugs, such as apalutamide, may help stop or reduce the growth of prostate cancer cell growth by blocking the attachment of androgen to its receptors on cancer cells, a mechanism similar to stopping the entrance of a key into its lock. Adding apalutamide to the usual hormone therapy and radiation therapy after surgery may stabilize prostate cancer and prevent it from spreading and extend time without disease spreading compared to the usual approach.

The purpose of the study is to evaluate effect of benralizumab on structural and lung function changes in severe eosinophilic asthmatics. Changes will be assessed over 48 week treatment period in patients with persistent symptoms despite standard therapy of inhaled corticosteroids (ICS) plus long acting B2-agonist (LABA) with or without additional controller medication. Patients who complete treatment will enter 4 weeks follow-up period. Read Less

This study is researching an investigational drug, odronextamab, in adult patients B-cell non-Hodgkin's lymphoma (B-NHL). The main purpose of this study is to assess the effectiveness of odronextamab in destroying cancer cells and to learn more about the safety of odronextamab. The study is looking at several other research questions, including: * To see if odronextamab works to destroy cancer cells * Side effects that may be experienced by people taking odronextamab * How odronextamab works in the body * How much odronextamab is present in the blood Read Less

This phase III trial tests two hypotheses in patients with low-risk and average-risk medulloblastoma. Medulloblastoma is a type of cancer that occurs in the back of the brain. The term, risk, refers to the chance of the cancer coming back after treatment. Subjects with low-risk medulloblastoma typically have a lower chance of the cancer coming back than subjects with average-risk medulloblastoma. Although treatment for newly diagnosed average-risk and low-risk medulloblastoma is generally effective at treating the cancer, there are still concerns about the side effects of such treatment. Side effects or unintended health conditions that arise due to treatment include learning difficulties, hearing loss or other issues in performing daily activities. Standard therapy for newly diagnosed average-risk or low-risk medulloblastoma includes surgery, radiation therapy, and chemotherapy (including cisplatin). Cisplatin may cause hearing loss as a side effect. In the average-risk medulloblastoma patients, this trial tests whether the addition of sodium thiosulfate (STS) to standard of care chemotherapy and radiation therapy reduces hearing loss. Previous studies with STS have shown that it may help reduce or prevent hearing loss caused by cisplatin. In the low-risk medulloblastoma patients, the study tests whether a less intense therapy (reduced radiation) can provide the same benefits as the more intense therapy. The less intense therapy may cause fewer side effects. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of cancer cells. The overall goals of this study are to see if giving STS along with standard treatment (radiation therapy and chemotherapy) will reduce hearing loss in medulloblastoma patients and to compare the overall outcome of patients with medulloblastoma treated with STS to patients treated without STS on a previous study in order to make sure that survival and recurrence of tumor is not worsened.

The purpose of this study is to evaluate the safety, tolerability, and preliminary efficacy of INCB057643 as monotherapy or combination with ruxolitinib for participants with myelofibrosis (MF) and other myeloid neoplasms. Read Less

Adverse childhood experiences (ACEs) are directly related to cardiovascular morbidity and mortality, and impaired vascular endothelial function (VEF) is an independent predictor of future cardiovascular disease (CVD) risk \[1, 2\]. Previous work from our lab (IRB 202010095) and others \[3\] demonstrates impaired VEF in young adults with prior exposure to ACEs even in the absence of clinical CVD risk factors. Sirtuin 1 (SIRT1) is a class III histone deacetylase (HDAC) that plays a role in regulating vascular homeostasis and reductions in SIRT1 are associated with age-related endothelial dysfunction \[4\]. We have shown that ACEs-related impairments in VEF are accompanied by reductions in SIRT1 \[5\]. However, the mechanisms by which ACE exposure promotes VEF remain unknown. The goal of this project is to establish proof of concept that alterations in vascular SIRT1 expression and activity mediate premature vascular aging in individuals with \>=4 ACEs compared to those with 0 ACEs and that, because NAD+ is an essential substrate for SIRT1, increasing NAD+ bioavailability will restore VEF in those with \>=4 ACEs. Thus, we will use a robust translational approach coupling in vivo and in vitro measures of endothelial function, inflammation, oxidative stress, and SIRT1 expression and activity in young adults with (n=30-35) versus without (n=30-35) ACE exposure in a cross-sectional study, and during a randomized controlled trial employing a novel 4-week nicotinamide riboside (NR) supplementation approach to increase SIRT1 activity by increasing cellular NAD+ in ACE+ (n=15/group) to accomplish the following specific aims: 1. Determine the mechanisms by which ACE exposure alters the regulation of VEF by SIRT1. We hypothesize that compared to those without ACEs (ACE-), ACE+ will have (H1a) elevated endothelial oxidative stress and inflammation, (H1b) accompanied by reduced endothelial SIRT1 expression and increased p66SHC expression and acetylation of p65 and p53, (H1c) in association with lower VEF. 2. Determine how targeting SIRT1 by increasing NAD+ bioavailability affects VEF in young adults with ACEs. We hypothesize that systemic NR supplementation will (H2a) augment cellular SIRT1 activity and (H2b) improve VEF in ACE+. \[1\] Felitti, V.J., Anda, R.F., Nordenberg, D., Williamson, D.F., Spitz, A.M., Edwards, V., Koss, M.P., \& Marks, J.S.

The purpose of this research study is to explore using MRI scans with xenon to better image lung function, how lung function changes after radiation therapy, and to guide radiation therapy away from parts of the lung that have good function. This project is foundational to performing additional studies to establish if novel MRI imaging can serve as a guidance tool for lung cancer radiation treatment. Read Less
