Pembrolizumab in Treating Younger Patients With Recurrent, Progressive, or Refractory High-Grade Gliomas, Diffuse Intrinsic Pontine Gliomas, Hypermutated Brain Tumors, Ependymoma or Medulloblastoma
This phase I trial studies the side effects and best dose of pembrolizumab and to see how well it works in treating younger patients with high-grade gliomas (brain tumors that are generally expected to be fast growing and aggressive), diffuse intrinsic pontine gliomas (brain stem tumors), brain tumors with a high number of genetic mutations, ependymoma or medulloblastoma that have come back (recurrent), progressed, or have not responded to previous treatment (refractory). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may induce changes in the body's immune system, and may interfere with the ability of tumor cells to grow and spread.

Pembrolizumab (MK-3475) in Patients With Recurrent Malignant Glioma With a Hypermutator Phenotype
The purpose of this study is to test if the study drug called pembrolizumab could control the growth or shrink the cancer but it could also cause side effects. Researchers hope to learn if the study drug will shrink the cancer by half, or prevent it from growing for at least 6 months. Pembrolizumab is an antibody that targets the immune system and activates it to stop cancer growth and/or kill cancer cells.

Pembrolizumab With Carboplatin/Paclitaxel in Patients With Metastatic Melanoma
This is a multi-center, open-label, Phase II clinical trial evaluating pembrolizumab in combination with carboplatin/paclitaxel as a treatment in unresectable locally advanced or metastatic melanoma.

Pembrolizumab With Combination Chemotherapy in Treating Participants With Locally Advanced or Metastatic Small Cell/Neuroendocrine Cancers of Urothelium or Prostate
This phase Ib trial studies how well pembrolizumab works with combination chemotherapy in treating participants with small cell/neuroendocrine cancers of the urothelium or prostate that has spread to nearby tissue or lymph nodes or that has spread to other places in the body. Monoclonal antibodies, such as pembrolizumab, may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as etoposide, docetaxel, cisplatin, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving pembrolizumab with platinum-based chemotherapy may...

Pembrolizumab With Liver-Directed or Peptide Receptor Radionuclide Therapy for Neuroendocrine Tumors and Liver Metastases
This pilot phase II trial studies how effective pembrolizumab and liver-directed therapy or peptide receptor radionuclide therapy are at treating patients with well-differentiated neuroendocrine tumors and symptomatic and/or progressive tumors that have spread to the liver (liver metastases). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Liver-directed therapies such as radiofrequency ablation, transarterial embolization, yttrium-90 microsphere radioembolization, and cryoablation may help activate the immune system in order to shrink tumors...

PEP-CMV in Recurrent MEdulloblastoma/Malignant Glioma
The primary goal of this prospective clinical trial is to evaluate the safety of PEP-CMV in patients with recurrent medulloblastoma and malignant glioma. Patients with histologically-proven medulloblastoma or malignant glioma who had received prior therapy for their initial diagnosis and subsequently had tumor recurrence/progression may be enrolled any time after recurrence/progression regardless of prior adjuvant therapy. PEP-CMV is a vaccine comprised of Component A, a synthetic long peptide (SLP) of 26 amino acid residues from human pp65. In May 2021, enrollment on the study was temporarily suspended due to delays in vialing the PEP-CMV study vaccine.

Perioperative Evaluation of Cerebellar Tumors
This is a prospective, cohort study to evaluate the impact of cerebellar functional topography on perioperative outcomes related to cognition and motor ataxia in patients with cerebellar tumors.

Personalized PRRT of Neuroendocrine Tumors
In this study, peptide receptor radionuclide therapy (PRRT) with 177Lu-Octreotate (LuTate) will be personalized, i.e. administered activity of LuTate will be tailored for each patient to maximize absorbed radiation dose to tumor, while limiting that to healthy organs. The purpose of this study is to: - Assess the objective (radiological), symptomatic and biochemical response rates following an induction course of personalized PRRT; - Assess the overall, the disease-specific, and the progression-free survival following P-PRRT; - Correlate therapeutic response and survival with tumor absorbed radiation dose; - Evaluate the acute, subacute and...

Personalized Radiation Therapy for GBM
The study is a pilot study to estimate the efficacy of personalized dose-escalation radiation therapy in patients with glioblastoma, as measured by estimating the median of progression-free survival. Toxicity, patterns of recurrence, and overall median survival will be measured as secondary endpoints. Adverse events will be monitored.

Personalized Risk-Adapted Therapy in Post-Pubertal Patients With Newly-Diagnosed Medulloblastoma
Medulloblastoma is a rare brain malignancy, mainly affecting children. Treatment of this rapidly growing tumor begins with maximal surgical removal plus radiation and chemotherapy. Treatment toxicity is high. Post-pubertal and pediatric medulloblastomas are biologically and prognostically different, which mandates age-adapted treatment strategies. Patients after puberty bear an intermediate to high prognostic risk. This means that a large number of these patients, are faced with death and/or disability (mainly neurocognitive). Therefore, the scientific and medical need is high. One of the genetic subgroups of medulloblastoma, the SHH-subgroup (Sonic HedgeHog- subgroup), is highly...
