Leptomeningeal Disease
Conditions
Brief summary
To determine the safety of intrathecal (IT) PD1 antibody for Intrathecal application of PD1 antibody in metastatic solid tumors with leptomeningeal disease of solid tumors.
Detailed description
Leptmeningeal disease (LMD) is an aggressive subtype of metastatic disease in the central nervous system (CNS) and has a poor prognosis with a median overall survival of a few months.The IT-PD1 trial group wants to contribute to an improvement of this situation for LMD patients by using an intrathecal application route for the PD1 antibody, i.e. a drug that has shown clinical efficacy in the underlying tumor via the intravenous route.
Interventions
Nivolumab (OPDIVO®) is a marketed pharmaceuticals material authorized in the European Union. This study uses an off-label route of administration of nivolumab. Subjects with leptomeningeal disease in solid tumours with an approved indication for intravenous treatment with the PD1 antibody will receive an intrathecal application of nivolumab. A total of six i.th. applications will be performed every 14 days. The intrathecal administration will be performed via an Ommaya reservoir or another intraventricular catheter.

Study design
Intervention model description
This is a single arm phase 1 trial with two parts. For part I (3+3 Design) there will be four cohorts: Cohort 1 with a fix dose of 20 mg, Cohort 2 with a fix dose of 30 mg, Cohort 3 with a fix dose of 40 mg and Cohort 4 with a fix dose of 50 mg. The dosage in the expansion part II will be fixe dosage for all patients depending on the results from Part I

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Assessment of Adverse Events for Dose Limiting Toxicities [Safety and Tolerabillity] | up to 4 months after last dose | This trial will investigate the maximum tolerable dose and safety of intrathecal PD1 antibody administration in LMD of metastatic solid tumors with a registered indication for treatment with intravenous PD1 antibody or PD-1L antibody. The safety endpoints will be assessed by a review of adverse events and serious adverse events according to CTCAE up to 4 months days after last dose.Subjects will undergo 6 cycles each 14 days in duration and a safety visit 7 days after the 3th dosage and 7 days after the 6th dosage.The appropriate dose for the expansion phase (Part II) is based on the results in Part I (dose escalation phase) and will define the maximum tolerable fix dose in Part II. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Overall Survival | last follow-up, up to 4 months after last dose | The secondary endpoint is overall survival defined as the time interval from the date of first study administration to the date of progression. |
