Summary

This study consists of 2 parts: Dose Escalation Part 1 and Dose Expansion Part 2. The Dose Escalation Part 1 will evaluate the safety and tolerability of Avelumab in combination with Lenvatinib and determine the recommended Avelumab and Lenvatinib dose for expansion. Dose Expansion Part 2 will assess the efficacy of Avelumab in combination with Lenvatinib by Progression-free Survival in participants with pre-defined primary central nervous system (CNS) tumors.

Conditions

Interventions

DRUG

Avelumab

Participants with primary CNS malignancies who have received at least 1 prior therapy will be enrolled into Dose Escalation Part 1 and will receive intravenous infusion at a flat dose or weight based dose of Avelumab, every 2 weeks (Q2W) until progression, unacceptable toxicity, or withdrawal of consent. Enrollment into part 1 of the study will end when Maximum tolerated dose (MTD) and/or a safe Recommended Dose for Expansion (RDE) for the expansion cohort is determined. Participants with defined CNS tumors will be enrolled into Dose Expansion Part 2 and will receive RDE in Part 2 until progression, unacceptable toxicity, or withdrawal of consent.

DRUG

Lenvatinib

Participants with primary CNS malignancies who have received at least 1 prior therapy will be enrolled into Dose Escalation Part 1 and will receive daily oral escalated dose level of Lenvatinib until progression, unacceptable toxicity, or withdrawal of consent. Enrollment into part 1 of the study will end when MTD and/or a safe Recommended Dose for Expansion (RDE) for the expansion cohort is determined. Participants with defined CNS tumors will be enrolled into Dose Expansion Part 2 and will receive RDE of Lenvatinib in Part 2 until progression, unacceptable toxicity, or withdrawal of consent.
