Brain Cancer Vaccine Gets Positive Phase 2 Results

Agenus Inc. today announced that a recent analysis from a Phase 2 trial in patients with newly diagnosed glioblastoma multiforme (GBM) treated with Prophage Series G-100 (HSPPC-96) in combination with the current standard of care (radiation and temozolomide) showed an almost 18 month median progression free survival (PFS), which represents a 160% increase versus current standard of care alone. This analysis confirms continuation of the positive trends from the Phase 2 HSPPC-96 newly diagnosed GBM trial first reported at the 81st American Association of Neurological Surgeons (AANS) Annual Scientific Meeting in May 2013.   

 “These additional results from the Phase 2 trial of HSPPC-96 in patients with newly diagnosed GBM are extremely encouraging and certainly justify a definitive randomized study,” said Andrew T. Parsa, MD, PhD, lead clinical investigator and chair of Neurosurgery at Northwestern Memorial Hospital and Northwestern University Feinberg School of Medicine. “The patient-specificity and lack of toxicity, combined with patient selection to optimize immunotherapy efficacy, could position this vaccine as a break-through treatment for newly diagnosed GBM patients in the years ahead.”  Based on these findings, Agenus plans to hold an end of Phase 2 meeting with the US Food and Drug Administration (FDA) to discuss a Phase 3 trial that could potentially lead to marketing approval of the HSPPC-96 vaccine as a treatment for patients with newly diagnosed GBM. Click here to view the full press release from Agenus.
