Pembrolizumab for brain infection in people with weakened immune systems

Progressive Multifocal Leukoencephalopathy

Treatments studied

Part of Brain & nervous system, Infections clinical trials.

This trial tests if pembrolizumab, an immunotherapy drug, can help fight a rare brain virus called PML in people whose immune systems are weakened but not due to HIV. The goal is to see if it improves recovery.

Summary written for real people, not researchers, by Clin2.

Phase

Enrollment
33 people
Ages
18 years and older

Who can take part

  • You must be 18 or older.
  • You must have been diagnosed with PML (a brain infection) less than 2 months ago.
  • The virus causing PML must be found in your spinal fluid.
  • You cannot have HIV, multiple sclerosis, or certain autoimmune diseases that might improve with standard treatment.
  • You must not be pregnant, plan to become pregnant, or breastfeed during the study.

Study of PML in patients, at-risk people, and healthy volunteers

This study follows people with suspected or confirmed progressive multifocal leukoencephalopathy (PML), people at higher risk, and healthy volunteers. It uses visits, brain imaging (MRI), and stored biological samples to better understand how PML progresses and who is at risk.

Testing how the brain absorbs anti–CD8 therapy in nervous system disease

This Phase 1 study tests a small drug (called an anti–CD8+ T cell minibody) to see how much reaches the brain. It may help researchers understand how to deliver similar treatments for multiple sclerosis, progressive multifocal leukoencephalopathy (PML), or other brain inflammation when the brain’s protective barrier is “open.”

Study of PML risk in MS patients taking Zeposia

This study looks at people with multiple sclerosis who have taken Zeposia (ozanimod) and later developed a rare brain infection called PML. The goal is to understand how often this happens and to confirm cases.

T-cell therapy for progressive multifocal leukoencephalopathy (PML)

This trial tests a T-cell therapy for people with PML, a rare brain infection. It aims to boost your immune system to fight the virus causing PML. You may be eligible if you have PML not caused by HIV, natalizumab, or certain recent treatments.
