Abstract :

Targeting Cerebraca ® wafer, also known as BP/polymer wafer, is a biodegradable wafer for interstitial implantation comprises butylidenephthalide (BP; the active moiety; EF-001) and Carboxyphenoxypropane-Sebacic Acid Copolymer (CPPSA).

The anti-glioblastoma pharmacology effect of BP was identified in yellowish brown root of the plant Angelica sinensis, a well-known Chinese medicine.

The antitumor effects of A. sinensis extracts were firstly evaluated in several human cancer cell lines, including a human glioblastoma multiform (GBM) cell line. These antitumor activity was suggested resulting from the effects of BP in suppression of telomerase level (Lin et al. 2011), up-regulation of nuclear receptor Nur77 (an apoptosis mediator) (Lin et al., 2008), reducing glioma migration and invasion mediated by Axl-1 tyrosine receptor (Yen et al., Oncogene, 2016) and tumor stem cell Sox-2 genes (unpublished data). More importantly, BP further showed the effects on reversing Temozolomide (TMZ) resistance by suppressing O6-methylguanine-DNA-methyltransferase (MGMT) mRNA and protein expression (Harn et al., 2013). Taken together, the targeting genes of BP are Axl/EZH2/SOX2, telomerase, DNA repair gene MGMT. In order to overcome the limitation of blood-brain barrier, a local interstitial delivery system which BP incorporated into a biodegradable polyanhydride material CPPSA, namely, the BP/polymer wafer was applied. This novelty contributes the efficient effects on survival (2.44 time prolonged more than Gliadel® wafers).

At present, we have completed the project in a chemical manufacturing and control, preclinical efficacy and preclinical safety assessment and other tests. The IND of Cerebraca® wafer has been approved by FDA for phase I/IIa. This clinical trial will be conducted at Tzu-Chi University Hospital in, Hualien, Taiwan.

So far, we have finished cohort II six patients study. No safety issue is found. The first patient has been extending eleven months.
