Blaze Bioscience Announces the Initiation of Pivotal Clinical Trial for Tumor Paint: BLZ-100 (tozuleristide) and the Canvas Imaging System

Blaze Bioscience, Inc., the Tumor Paint Company®, a biotechnology company dedicated to improving the lives of cancer patients through development and commercialization of products for fluorescence guided surgery, today announced they have enrolled the first patient at Seattle Children’s Hospital in their Phase 2/3 pivotal study entitled “A randomized, blinded study of fluorescence detection of pediatric primary central nervous system tumors in subjects receiving tozuleristide and imaged with the Canvas System.”

The randomized, blinded, multi-center, single dose Phase 2/3 study in pediatric patients with central nervous system tumors will assess the safety and efficacy of BLZ-100 as well as the performance of the Canvas System. The trial is expected to enroll 114 patients at fifteen (15) leading U.S. pediatric cancer surgery centers throughout the U.S. that are participants in the Pacific Pediatric Neuro-Oncology Consortium (PNOC).

"There is an urgent unmet need for a tumor-targeted imaging agent to enable real-time intraoperative distinction between malignant and normal tissue to improve neurosurgical outcomes, either as increased chance of a gross total resection or decreased risk of inadvertent normal brain resection or both. We believe BLZ-100 may be the first agent that could allow us to address this need in the pediatric population. We are excited to work with Blaze and PNOC in the conduct of this study,” said Sarah M. Leary, M.D., M.S., Seattle Children’s Hospital, and PNOC Study Chair for the BB-006 (PNOC012) clinical trial. “We would also like to acknowledge the contribution of the Norcliffe Foundation and Gateway for Cancer Research in providing financial support enabling the study.”

"Treating our first patient in a pivotal trial is the next step in realizing Blaze’s vision to improving cancer surgery for all solid tumor patients. The CDC reports that brain cancer is the number one cancer killer of children, making this a compelling place to start. The ability of BLZ-100 to detect pediatric tumors sets it apart from other fluorescence-based agents," said Heather Franklin, CEO of Blaze Bioscience.

About BLZ-100 (tozuleristide)

BLZ-100 (tozuleristide) is the first product candidate from Blaze’s Tumor Paint platform and consists of a targeting peptide and a fluorescent dye, which emits light in the near-infrared range. Tumor Paint products are designed to provide real-time, high-resolution intraoperative visualization of cancer cells, potentially enabling more precise, complete resection of cancer and sparing of normal adjacent tissue throughout surgery. BLZ-100 has been tested in four Phase 1 clinical trials and has demonstrated clinical proof of concept in brain, breast and skin cancers. Additional potential applications of BLZ-100 include prostate, lung, colorectal and other solid tumor cancers. BLZ-100, an investigational agent, is being evaluated in a Phase 2/3 clinical study in pediatric CNS tumors. More details about ongoing trials are available at

About the Canvas Imaging System

The Canvas Imaging System developed and manufactured by Teal Light Surgical, Inc. (a wholly-owned subsidiary of Blaze Bioscience Inc.) is designed to provide high-sensitivity detection of NIR light in the operating theater under ambient light conditions. The first Canvas Imaging System under development is adapted for use with surgical microscopes and detects both BLZ-100 and indocyanine green (ICG).

About Blaze Bioscience

Blaze Bioscience, Inc. is a privately held biotechnology company dedicated to improving the lives of cancer patients. Blaze was founded in 2010 by Dr. Jim Olson, a pediatric neuro-oncologist at the Fred Hutchinson Cancer Research Center and Seattle Children’s Hospital, and Heather Franklin, a former senior executive at ZymoGenetics. Blaze is working to develop Tumor Paint products and related therapeutics. Surgery is first-line therapy for most solid tumor cancers and Tumor Paint products have the potential to improve cancer surgery by providing real-time, high-resolution visualization of cancer cells throughout surgery. The ability to see cancer cells in real time and high resolution throughout surgery should enable better detection and more complete and precise surgical removal of cancer—while sparing surrounding normal tissue.
