Testing if High Dose Radiation Only to the Sites of Brain Cancer Compared to Whole Brain Radiation That Avoids the Hippocampus is Better at Preventing Loss of Memory and Thinking Ability
NCT04804644
Recruiting
This phase III trial compares the effect of stereotactic radiosurgery to standard of care memantine and whole brain radiation therapy that avoids the hippocampus (the memory zone of the brain) for the treatment of small cell lung cancer that has spread to the brain. Stereotactic radiosurgery is a specialized radiation therapy that delivers a single, high dose of radiation directly to the tumor and may cause less damage to normal tissue. Whole brain radiation therapy delivers a low dose of radiat... Read More

Two Studies for Patients With High Risk Prostate Cancer Testing Less Intense Treatment for Patients With a Low Gene Risk Score and Testing a More Intense Treatment for Patients With a High Gene Risk Score, The PREDICT-RT Trial
NCT04513717
Recruiting
This phase III trial compares less intense hormone therapy and radiation therapy to usual hormone therapy and radiation therapy in treating patients with high risk prostate cancer and low gene risk score. This trial also compares more intense hormone therapy and radiation therapy to usual hormone therapy and radiation therapy in patients with high risk prostate cancer and high gene risk score. Apalutamide may help fight prostate cancer by blocking the use of androgen by the tumor cells. Radiatio... Read More

Everyday Memory Impairment in PD-related Cognitive Decline
NCT04474379
Recruiting
The investigators will aim enroll participants into our study within 3-6 months after their parent study visit so the investigators can utilize some key data points (e.g. PD-MCI diagnosis, rs-fcMRI data) from that study. PD participants will participate in a single-blind RCT with two treatment arms: process training and strategy training (Fig 4). They will complete pre-training assessment (Pre), be randomized to treatment arm (1:1 ratio stratified by sex), and then complete 8 training sessions o... Read More

Testing the Addition of the Drug Apalutamide to the Usual Hormone Therapy and Radiation Therapy After Surgery for Prostate Cancer, INNOVATE Trial
NCT04134260
Recruiting
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 mechani... Read More

Benralizumab Airway Remodeling Study in Severe Eosinophilic Asthmatics
NCT03953300
Recruiting
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.

A Study to Assess the Anti-Tumor Activity and Safety of Odronextamab in Adult Patients With B-cell Non-Hodgkin Lymphoma Who Have Been Previously Treated With Other Cancer Therapies
NCT03888105
Recruiting
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...

The Role of Circadian Clock Proteins in Innate and Adaptive Immunity
NCT03482245
