Helix BioPharma Corp. Announces Collaboration with Moffitt Cancer Center

TORONTO, ONTARIO--(Marketwired - July 11, 2017) - Helix BioPharma Corp. (TSX:HBP)(FRANKFURT:HBP) ("Helix" or the "Company"), an immuno-oncology company developing innovative drug candidates for the prevention and treatment of cancer, today announced that it has entered into a collaboration agreement with Moffitt Cancer Center to extract radiomics data using their proprietary HealthMyne platform from CT scans of late stage lung cancer patients treated with L-DOS47.

Radiomic features have the potential to uncover disease characteristics that would be otherwise missed during a routine CT or PET scan analysis. These distinctive imaging features may be useful for predicting prognosis and therapeutic response for various conditions. In collaboration with Helix, the Moffitt's Cancer Imaging and Technology Center of Excellence imaging informatics specialists will build response prediction models using delta radiomics from CT scans of patients treated with L-DOS47 in the LDOS002 Phase I monotherapy study.

Helix will be teaming up with Dr. Robert Gillies, Director of Moffitt's Cancer Imaging and Technology Center of Excellence and the Martin Silbiger Chair of Cancer Imaging and Metabolism. Dr. Gillies has received numerous local, national and international awards for his teaching and research. His research is focused on functional and molecular imaging of cancer with an emphasis on the use of imaging to inform evolutionary models of carcinogenesis and response to therapy.

"Both Helix and the Moffitt team have a common research interest that can advance the knowledge of tumour microenvironment and how it influences carcinogenesis," said Heman Chao, Ph.D., Chief Executive & Science Officer of Helix. "The data generated from this project may identify a prognostic phenotype which Helix can incorporate in future clinical trials with L-DOS47."

"Typical responses of cancer to therapies are measured by simply the size of the tumor," said Dr. Robert Gillies. "We know that, for many cancers and many therapies, changes in size alone do not predict eventual overall outcome. To address this deficiency, we have created an approach called 'Radiomics', wherein multiple features are extracted from patients' images (MRI, PET, or CT scans) and we can determine which of these features combine to give higher predictive value. With another partner, HealthMye, this approach has been incorporated this into an FDA-approved clinical system, and we will use this system to analyzed images from a prior clinical trial that was conducted by Helix. We expect that this work will be performed expeditiously, and that we will soon know if radiomic features can predict responsiveness to L-DOS47."

Collaboration Overview

Under this research plan titled "Radiomics of Response", Moffitt's Cancer Imaging and Technology Center of Excellence imaging informatics specialists will extract longitudinal radiomic features from CT and PET scans of late-stage lung cancer patients treated with L-DOS47. These features are extracted from both primary and index lesion. The research project will be performed under the supervision of Dr. Robert Gillies. Dr. Gillies is the Director of Moffitt's Cancer Imaging and Technology Center of Excellence. Dr. Gillies expertise in the area of radiomics will be vital to the success of this project. Following approval from the Moffitt Cancer Center Institutional Review Board, the team at Moffitt will use their proprietary HealthMyne platform to extract quantitative radiomic data from CT scans obtained from Phase I patients treated with L-DOS47. The research radiologists will confirm locations, and score primary lesions with sematic scoring schema developed by the team at Moffitt. In collaboration with Helix, Moffitt imaging informatics specialists will build response prediction models using delta radiomics.
