A Phase III Study of SYHA1813 for Recurrent or Progressive High-Grade Meningiomas

SYHA1813 vs Investigators' Choice Treatment in Patients With Recurrent or Progressive High-Grade Meningiomas: A Randomized, Controlled, Multicenter, Phase III Study

This is a randomized, controlled, open-label, multicenter, Phase III clinical study designed to compare the efficacy and safety of SYHA1813 versus treatment of investigators' choice in patients with recurrent or progressive high-grade meningioma not amenable to local therapy.

Study Overview

• Status: Not yet recruiting
• Conditions: High Grade Meningioma
• Intervention / Treatment: Drug: SYHA1813; Drug: Investigator's Choice Treatment

Detailed Description

Approximately136 participants with recurrent or progressive high-grade meningioma who have received surgical resection and radiotherapy will be enrolled and randomized 1:1 to receive either SYHA1813 (experimental group) or investigators' choice (control group) treatment. The primary endpoint is progression-free survival (PFS) assessed by blinded Independent Review Committee (BIRC) using the Response Assessment in Neuro-Oncology Working Group (RANO criteria) for meningioma.

• Study Type: Interventional
• Enrollment (Estimated): 136
• Phase: Phase 3
