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

Study Purpose

A Phase I/IIa Study to Determine the Maximum Tolerated Dose (MTD) and to Evaluate the Safety and Efficacy Profile of Cerebraca Wafer Plus Adjuvant Temozolomide (TMZ) in Patients With Recurrent High Grade Glioma. High grade gliomas, glioblastoma multiforme (grade IV) and anaplastic anaplastic astrocytoma (Grade III), are the most comment malignant brain tumor. The cause of gliomas remains unknown. Despite of several researches on environmental hazards and genetic alterations, no direct causes were found. Patient suffering from glioma usually develops symptoms such as headaches, seizures, memory loss and changes in behavior in its early phase. At later stages, patients may encounter loss of movement and sensation, language dysfunction and cognitive impairments depending on location and size of the tumor. The average survival of glioblastoma patients is 15 months regardless of the use of multimodal therapy. (Z)-BP/polymer wafer, designated as Cerebraca wafer, is a biodegradable wafer for interstitial implantation comprises (Z)-n-butylidenephthalide ((Z)-BP; the active moiety) and Carboxyphenoxypropane-Sebacic Acid Copolymer (CPPSA; the excipient). Cerebraca wafer, the first human-use drug product, is a biodegradable implant comprises (Z)-n-butylidenephthalide ((Z)-BP) and CPPSA. According to pre-clinical study, (Z)-BP could reduce glioma migration and invasion, it also could reduce the tumor stem cell marker gens.

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT03234595
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Arms & Interventions

Arms

Experimental: single arm

There is 1 treatment arm with 4 dose cohorts in Phase I and 1 treatment arm in Phase IIa.

Interventions

Drug: - Cerebraca wafer

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.
