Uptake and Biodistribution of 89Zirconium-labeled Ipilimumab in Ipilimumab Treated Patients With Metastatic Melanoma
Rationale: Ipilimumab, a monoclonal antibody targeting CTLA-4, is approved for the treatment of metastatic melanoma and significantly increases median overall survival. However, use of this drug is associated with immune related adverse events (IRAEs) like colitis, hepatitis, dermatitis, alveolitis and hypophysitis in 10-40% of the patients. In general IRAEs are manageable by cessation of ipilimumab in combination with treatment with corticosteroids or TNF-alpha blockade but they can be severe or even life-threatening. In addition, treatment with ipilimumab is expensive. Because of the high costs and the potential serious toxicity of ...
Use of a Tonometer to Identify Epileptogenic Lesions During Pediatric Epilepsy Surgery
Refractory epilepsy, meaning epilepsy that no longer responds to medication, is a common neurosurgical indication in children. In such cases, surgery is the treatment of choice. Complete resection of affected brain tissue is associated with highest probability of seizure freedom. However, epileptogenic brain tissue is visually identical to normal brain tissue, complicating complete resection. Modern investigative methods are of limited use. An important subjective assessment during surgery is that affected brain tissue feels stiffer, however there is presently no way to determine this without committing to resecting the affected area. It...
Use of DTT to Define Facial Nerve Position in Vestibular Schwannomas
Vestibular schwannomas (VS) arise from the vestibulocochlear (hearing and balance) nerve, located at the base of the brain. Although benign, VS can enlarge over time, resulting in debilitating symptoms; therefore, surgical removal is frequently offered. One significant risk of surgery is inadvertent injury to the facial nerve, which lies adjacent to the vestibulocochlear nerve. Currently, the nerve's course is only revealed during surgical dissection and injury can cause permanent facial weakness. It would therefore be useful for the surgeon to know the course of the nerve before operating. To this end, a new MRI technique known as...
Use of Optune TTF With Radiation as an Alternative for Elderly Patients With Primary CNS Lymphoma
This study will compare the overall survival (OS) time of elderly patients who would not tolerate standard chemotherapy for PCNSL treated with WBXRT together with Optune-TTF to those treated with whole-brain radiotherapy alone. Standard treatment of primary central nervous system lymphoma (PCNSL) for patients with good performance status involves high-dose methotrexate-based chemotherapy regimens and whole-brain radiation therapy (WBXRT). Although up to 20% of patients with PCNSL are 80 years of age or older, little data exist with regard to optimal treatment of this patient population and they often do not qualify for clinical trials. In...
Using a Novel Functional MRI Technique to Evaluate for Neurotoxicity
The purpose of this study is to test resting state functional Magnetic Resonance Imaging (rsfMRI) scans to see if rsfMRI scans are better than the standard task based fMRI scans at diagnosing or monitoring central nervous system lymphoma.
Using MRI-Guided Laser Heat Ablation to Induce Disruption of the Peritumoral Blood Brain Barrier to Enhance Delivery and Efficacy of Treatment of Pediatric Brain Tumors
By employing a combination of advanced MRI techniques and correlative serum biomarkers of blood brain barrier (BBB) disruption, the investigators plan to develop a powerful, first of its kind clinical algorithm in pediatrics whereby the investigators can measure and identify the window of maximal BBB disruption post MLA to 1) allow for an alternative to surgery in incompletely resected tumors, 2) allow for optimal chemotherapeutic dosing to achieve the greatest benefits and the least systemic side effects and 3) distinguish subsequent tumor progression from long-term MLA treatment effects. Preliminary data in adult imaging studies have...
Utility of Perfusion MRI to Detect Radiation Necrosis in Patients With Brain Metastases
This trial studies how well dynamic susceptibility contrast-magnetic resonance imaging (MRI) works in determining radiation necrosis and tumor progression in participants with cancer that has spread to the brain and are being treated with radiation therapy. Diagnostic procedures, such as dynamic susceptibility contrast-MRI, may improve the ability to determine indeterminate post-treatment changes seen on imaging after radiation therapy.
UV1 Vaccination Plus Nivolumab and Ipilimumab in Treatment of Melanoma
UV1 is a therapeutic cancer vaccine that has been explored in prostate, lung cancer, in combination with ipilimumab in malignant melanoma and in combination with pembrolizumab in metastatic melanoma. This study will explore the Efficacy and Safety of UV1 administered with GM-CSF in combination with nivolumab and ipilimumab.
UV1 Vaccine With Pembrolizumab for Patients With Unresectable or Metastatic Melanoma
UV1 is a therapeutic cancer vaccine that has been explored in prostate and lung cancers, and in combination with ipilimumab in malignant melanoma. This study will explore the safety, tolerability and efficacy of UV1 administered with GM-CSF in melanoma patients who are also receiving pembrolizumab.
Vaccination With 6MHP, With or Without Systemic CDX-1127, in Patients With Stage II-IV Melanoma
This study evaluates whether it is safe to administer a peptide vaccine (6MHP) with adjuvants and the CDX-1127 monoclonal antibody, and whether the adjuvants and the CDX-1127 monoclonal antibody boost immune responses to the vaccine. In this study, the adjuvants are Montanide ISA-51 and polyICLC. The investigators will monitor these effects by performing tests in the laboratory on participants' blood and tissue from a vaccine site.
