Summary

This trial is testing a drug that may treat cancer spread to the brain/spine.

Who is the study for?
This trial is for adults with confirmed solid tumor metastases in the brain or spinal cord. Participants must have a measurable lesion, be in good physical condition (ECOG ≤2), and have a life expectancy over 6 weeks. Specific cohorts include untreated asymptomatic brain metastases, carcinomatous meningitis, and melanoma with limited brain metastases suitable for radiosurgery.
What is being tested?
The study tests Pembrolizumab's effectiveness on central nervous system metastases from various tumors. It includes MRI and PET/CT imaging to track changes, along with Stereotactic Radiosurgery for certain patients. The trial has multiple cohorts based on different disease characteristics.
What are the potential side effects?
Pembrolizumab may cause immune-related side effects such as inflammation of organs, infusion reactions like fever or chills, fatigue, skin rash, digestive issues including diarrhea or liver problems, hormonal gland problems leading to hormone imbalances.

All patients enrolled in this study will receive some form of active treatment.
All Individual Drugs Already Approved
Therapies where all constituent drugs have already been approved are likely to have better-understood side effect profiles.

Trial Design

4Treatment groups
Experimental Treatment
Group I: Progressive Brain Metastases-Cohort BExperimental Treatment3 Interventions
- Progressive Brain Metastases * Baseline Brain MRI and PET CT * For all cohorts, pembrolizumab will be administered every 3 weeks, with 21 consecutive days defined as a treatment cycle. Treatment will be administered on an outpatient basis. * Brain MRI and PET/CT
Group II: Previously Untreated Brain Metastases-Cohort AExperimental Treatment3 Interventions
- Previously Untreated Brain Metastases * Baseline Brain MRI and PET CT * For all cohorts, pembrolizumab will be administered every 3 weeks, with 21 consecutive days defined as a treatment cycle. Treatment will be administered on an outpatient basis. * Brain MRI and PET/CT
Group III: Neoplastic Meningitis-Cohort CExperimental Treatment3 Interventions
* Neoplastic Meningitis * Histologically confirmed solid malignancy * Positive Cytology * Baseline Brain MRI * For all cohorts, pembrolizumab will be administered every 3 weeks, with 21 consecutive days defined as a treatment cycle. Treatment will be administered on an outpatient basis. * Brain MRI and PET/CT
Group IV: 1-4 Brain Metastases from Melanoma Cohort DExperimental Treatment4 Interventions
