Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

The disease, disorder, syndrome, illness, or injury that is being studied.
This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational drug to learn whether the drug works in treating a specific disease. "Investigational" means that the drug is being studied. Many brain cancers show over expression of a protein called cyclin D1. That means that the body makes too much cyclin D1, which affects enzymes called CDK 4 and CDK 6. Enzymes are substances in the body that help reactions between cells happen. Too much cyclin D1 triggers CDK 4 and CDK 6 to make more cells than normal. This extra cell production leads to the growth of tumors. In laboratory studies, abemaciclib was able to enter the brain, stop CDK 4 and CDK 6 from making cells, and slow growth of glioblastoma in mice. Pembrolizumab (MK-3475) has been studied in lab experiments and in other types of cancer. Information from these studies suggests that Pembrolizumab (MK-3475) may be beneficial inrecurrent glioblastoma (GBM). Pembrolizumab (MK-3475) is a humanized monoclonal antibody. An antibody is a common type of protein made in the body in response to a foreign substance. Antibodies attack foreign substances and protect against infection. Antibodies can also be produced in the laboratory for use in treating patients; an antibody that is made in the lab is also known as a humanized monoclonal antibody that is designed to block the action of the receptor, PD-1. PD-1 works to help tumor cells continue to grow and multiply. There are now several approved antibodies for the therapy of cancer and other diseases. .
