The purpose of this study is to determine whether AGuIX (Activation and Guidance of Irradiation by X-ray) gadolinium-based nanoparticles make radiation work more effectively in the treatment of patients with brain metastases that are more difficult to control with stereotactic radiation alone.
Background: Epstein-Barr virus (EBV) is the primary cause of infectious mononucleosis, commonly known as mono. EBV infects more than 90% of the world s population. Mono can be serious, and it can lead to severe illnesses like cancer and autoimmune diseases. Researchers want to test vaccines that may help prevent EBV and associated diseases. Objective: To test two EBV vaccines: EBV gH/gL/gp42-ferritin and EBV gp350-ferritin. Eligibility: Healthy EBV-negative or EBV-positive people aged 18 to 29. Design: Participants will be screened. They will have a physical examination. They will give blood and saliva samples. They will receive 3 doses of the study vaccine as an injection in the shoulder muscle. They will get either one vaccine or a combination of both vaccines. Participants will get their first dose of the vaccine at visit 1, the second dose about 30 days later, and the final dose about 90 days after that. Participants will be given a memory aid so they can record any symptoms and side effects between visits. This can be done either on paper or online through a link that is emailed to them. There are 6 required in-person visits. There are also 2 optional visits. In between the in-person visits are 7 telehealth visits or phone calls. Each visit may take up to 4 hours. The study will last for about 17 months. Participants will have the option of staying in the study for an additional year.
The purpose of this study is to collect and evaluate pregnancy outcomes, pregnancy complications, and fetal/neonatal/infant outcomes in women exposed to patisiran-LNP.
This research study is being done to help determine the safety and efficacy of gadolinium based nanoparticle, Activation and Guidance of Irradiation X (AGuIX), used in conjunction with MR-guided stereotactic body radiation therapy (SBRT) in the treatment of pancreatic cancer and lung tumors.
The purpose of this study is to see whether using the copper-64 (64Cu) or zirconium-89 (89Zr) radiolabeled PSMA-targeting C' dot tracer, termed 64Cu-NOTA-PSMAi-PEG-Cy5.5-C' dots or 89Zr-DFO-PSMAi-PEG-Cy5.5-C' dots, is a safe way to identify tumor cells before and during surgery for prostate cancer. The researchers want to determine whether pre-operative PET/MRI scans and intra-operative optical imaging performed in prostate cancer patients after the injection of one of these investigational tracers more accurately localizes cancerous deposits within the surgical bed as compared with conventional imaging scans alone. The researchers will study how the tracer travels through your body and where it is distributed. This study is the first time that the tracer will be used in patients undergoing surgery for prostate cancer.
This clinical trial will evaluate the combination of quaratusugene ozeplasmid with atezolizumab as maintenance therapy for patients with Extensive Stage Small Cell Lung Cancer (ES-SCLC). The study is comprised of 2 phases, a dose selection phase (Phase 1) and a safety and efficacy evaluation phase (Phase 2).
The trial aims to investigate the use of superparamagnetic iron oxide (SPIO) nanoparticles as a tracer for delayed sentinel lymph node dissection (d-SLND) in patients where upfront axillary surgery (SLND) is oncologically deemed unnecessary and should be avoided. This includes but is not limited to patients with a preoperative diagnosis of ductal cancer in situ of the breast (DCIS), an unclear BIRADS 4-5 planned for diagnostic excision or women planned for risk reducing mastectomy. SPIO is injected in the primary operation, and should final specimen pathology demonstrate invasive breast cancer, only then is an operation in the axilla (d-SLND) performed.
The purpose of this randomized study is to determine the safety and efficacy of quaratusugene ozeplasmid (Reqorsa) added to osimertinib in NSCLC patients with activating EGFR mutations who have progressed while on treatment with osimertinib. Quaratusugene ozeplasmid consists of non-viral lipid nanoparticles that encapsulate a DNA plasmid with the TUSC2 tumor suppressor gene and is the first systemic gene therapy for cancer. The study is comprised of a Phase 1 dose escalation portion and two Phase 2 portions evaluating safety and efficacy. Enrollment in the Phase 1 dose escalation portion is complete and the recommended Phase 2 dose (RP2D) was determined. Phase 2a has initiated and enrolled patients are treated with quaratusugene ozeplasmid at the RP2D in combination with osimertinib. In Phase 2b, patients will be randomized to receive either quaratusugene ozeplasmid plus osimertinib or platinum-based chemotherapy.
