A Phase II Clinical Study to Evaluate the Efficacy and Safety of Flazoparib Combined With Temozolomide After the Completion of Standard Concurrent Chemoradiotherapy (CCRT) in Newly Diagnosed Glioblastoma

"Fluzoparib: 100mg, po.bid. Q4W, d1-28, for a total of 6 cycles~Temozolomide (TMZ): 150-200 mg/m2, po. Q4W, d1-5, for a total of 6 cycles~If unacceptable toxicity occurs and a dose reduction is required, it is recommended to first reduce the dose from 100 mg (2 tablets) to 50 mg (1 tablet) twice a day. If further dose reduction is required, it is recommended to reduce the dose from 50 mg (1 tablet) twice a day to 50 mg (1 tablet) once a day. If it is still intolerable, the patient should withdraw from the clinical study.~The TMZ dose is adjusted by the investigator according to standard chemotherapy requirements. Adjuvant TMZ treatment of less than 6 cycles is allowed depending on the subject's condition (e.g. confirmed disease progression, intolerable toxicity, etc.). Tumor assessment is performed during two cycles of TMZ (q8w±7 days) during the study or when clinically indicated"
