Looking for participants

Intrathecal double checkpoint inhibition (IT-IO)

To determine the feasibility and explore the anti-tumor activity of intrathecal double immune checkpoint inhibition in patients with newly diagnosed leptomeningeal metastases of non-small cell lung cancer without driver mutation or melanoma.

Aim of the study

In our research project, we want to find out whether treatment with immunotherapy (immune checkpoint antibodies), which is injected locally into the fluid space surrounding the brain and spinal cord (subarachnoid space or cerebrospinal fluid space), is tolerable and enables better control of the tumor disease. This form of local administration of medication is called intrathecal therapy.

Who can take part?

Patients with leptomeningeal metastasis, stage IV non-small cell lung cancer, stage IV melanoma

Procedure

If you decide to participate, you will repeatedly receive the two drugs either via lumbar punctures (injections into the subarachnoid space or cerebrospinal fluid space) or via a surgically inserted reservoir on the head that allows the drugs to be injected directly into the cerebrospinal fluid (CSF). The therapy is applied during outpatient visits to our clinic. Inpatient stays are not necessary. The therapy is administered for as long as it is tolerated and the tumor disease is controlled, for up to 24 months. The injections are initially given 5 times at 3-week intervals and later at 4-week intervals.

Compensation

None
