A Phase I/IIa Study of Cerebraca Wafer Plus Adjuvant Temozolomide (TMZ) in Patients With Recurrent High Grade Glioma

Eligible patients will receive Cerebraca wafer implantation with adjuvant temozolomide (TMZ) for the safety and efficacy in this study. At Phase I, the MTD will be determined by DLT. At Phase IIa, up to 12 evaluable patients will be enrolled for the efficacy and safety of Cerebraca wafer implantation. At Phase IIa, the cavity surface after tumor removal will be maximally covered by Cerebraca wafer without exceeding the MTD defined at Phase I. Patients in Phase I receive treatment as designed for Phase IIa, the data will be incorporated into Phase IIa to reduce the patient number. The overall patient number in this study is therefore between 2 to 36 evaluable patients.
