Recruiting for Phase IIb Pentrys trial complete
Sydney oncology company AustCancer (ASX:ACU, OTCBB:ACUJY) announced today it has completed recruiting for its Phase IIb clinical trial of its Pentrys peptide vaccine in 40 male patients with hormone-refractory prostate cancer.
The multi-centre trial is being conducted by Cancer Trials Australia at Melbourne's Austin Health, Royal Melbourne Hospital and the Peter MacCallum Cancer Centre. It is designed to confirm the vaccine's safety and clinical efficacy.
The new vaccine is designed to elicit an antibody reaction to mutant peptides of the tumour-suppressor protein P53, which is abnormally displayed on the surface of tumour cells in about 50 per cent of all cancers.
