- Safety and Dose Limiting Toxicity (DLT) measured by number of subjects with adverse events (AEs) [ Time Frame: End of treatment (3 months) ]
Adverse events will only include those that are determined to be related to study drug.
A DLT will be defined as any one of the following adverse events occurring within 28 days from first dose of Avelumab. Central Nervous System (CNS) toxicities: Any grade 3 or higher central nervous adverse events, including but not limited to cerebral hemorrhage and new-onset neurologic deficit. Non-CNS toxicities: Any grade 3 or higher nonhematologic AE with the exception of alopecia and fatigue - Grade > 3 nausea, vomiting, or diarrhea despite maximal medical therapy - Grade > 3 laboratory value if 1)medical intervention is required to treat the patient or 2) the abnormality leads to hospitalization • Any grade 3 or 4 event that does not improve within 6 weeks
- Number of T Cells [ Time Frame: Up to 11 months ]The number of T cells in the cerebrospinal fluid (CSF) and the CSF cytokine activation profile in the CSF (relative to serum) measured before and after Avelumab administration.
- Activation Status of T Cells [ Time Frame: Up to 11 months ]The activation status of T cells in the cerebrospinal fluid (CSF) and the CSF cytokine activation profile in the CSF (relative to serum) measured before and after Avelumab administration.
- Leptomeningeal Disease (LMDz)/CNS Response Rate and Systemic Response Rate [ Time Frame: Up to 11 months ]Any solid brain metastases associated with LMDz will be assessed with Response Assessment in Neuro-Oncology (RANO)-Brain Metastases (BM) criteria. Responses in the rest of the body will be measured using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria.
- Overall Survival (OS) Rate at 3 months [ Time Frame: 3 months ]OS, utilizing 95% confidence interval (95%CI).
