SM-1 Combined With Temozolomide in Subjects With Refractory or Recurrent High-Grade Gliomas

The aim of this clinical trial is to evaluate the safety, preliminary effectiveness, and pharmacokinetic profiles of SM-1 (Obitrexate Fumarate Enteric-coated Pellet Capsules) combined with temozolomide, and conduct systematic dose exploration for the treatment of refractory or recurrent high-grade gliomas in adult patients. The core focus is to screen the optimal clinical dose regimen of SM-1, fully monitor adverse reactions, and preliminarily observe the anti-tumor efficacy of the combination regimen. The main questions it aims to answer are: * What is the safety profile and tolerability of different dose cohorts of SM-1 in combination with temozolomide in patients with refractory or recurrent high-grade gliomas? * What are the pharmacokinetic characteristics of SM-1 across different dose levels, supporting accurate dose optimization for subsequent clinical medication? * Can the optimized SM-1 combined regimen exert preliminary anti-tumor effectiveness in patients with refractory or recurrent high-grade gliomas, and confirm the recommended Phase II dose? Researchers will enroll eligible patients and assign them to different gradient dose groups of SM-1 for dose-escalation exploration, match with standardized temozolomide combination therapy, comprehensively collect full-cycle safety data, and preliminarily evaluate the clinical anti-tumor efficacy of different dose combinations to determine the optimal safe and effective therapeutic dose for subsequent large-scale clinical trials.

BC008-1A Injection for Recurrent CNS WHO G4 Glioma

The purpose of this Phase I clinical study is to evaluate the safety, preliminary efficacy and pharmacokinetic characteristics of BC008-1A injection in subjects with recurrent CNS WHO grade 4 glioma. This is a randomized and open-label study, with two dose groups set up, and 10 to 20 subjects will be enrolled in each group.
