Under the agreement, CrystalGenomics will receive an upfront payment of US $3 million and is eligible for development, regulatory and commercial-based milestones, as well as single-digit royalties on product sales in China. Total deal value for the China territory, including the upfront payment, is up to US $125 million.

On May 7, 2018, Aptose exercised its option to obtain the exclusive license from CrystalGenomics to develop and commercialize CG-806 worldwide outside of China and Korea. This new agreement extends that license agreement to include China.

"Licensing rights to CG-806 to include the China territory was a strategic decision," said William G. Rice, Ph.D., Chairman, President and Chief Executive Officer of Aptose. "Our preclinical work with CG-806 has demonstrated its superior activity to other FLT3 inhibitors on AML patient samples, its superior ability to kill B-cell malignancy patient samples relative to ibrutinib, and a favorable safety profile. We believe that CG-806 has the potential to serve as a transformational agent for multiple hematologic cancers, including AML, CLL and others."

"We are pleased to continue our relationship with the Aptose team, which recognized the exciting potential of CG-806 very early in its development," said Joong Myung Cho, Ph.D., Chairman and Chief Executive Officer of CrystalGenomics. "They have been laser focused on IND-enabling studies of CG-806, and we look forward to seeing CG-806 enter the clinic."

About CG-806

CG-806 is an oral, first-in-class pan-FLT3/pan-BTK multi-kinase inhibitor that represents a potential best-in-class therapeutic for patients with AML.

Aptose has been conducting Investigational New Drug (IND) enabling studies with CG-806, as well as numerous preclinical studies. When tested against fresh bone marrow samples from patients with AML, CG-806 demonstrated superior potency and range of activity relative to all other FLT3 inhibitors evaluated. Likewise, CG-806 demonstrated superiority over ibrutinib when tested against samples from CLL patients. The superior potency and breadth of activity against patient-derived hematologic malignancy cells is due to the ability of CG-806 to target wild type (WT) and all known mutant forms of FLT3 and BTK, and to suppress multiple signaling pathways that can rescue hematologic cancers from other agents. Once-daily oral dosing of CG-806 in murine xenograft models of human hematologic malignancies demonstrated tumor eradication in the absence of observable toxicity, and dose range finding studies have shown CG-806 to have a robust safety profile. Aptose expects to submit an IND in late 2018 and initiate clinical trials immediately thereafter.

The 22P1G cells constitute the cells in the Master Cell Bank (MCB) that were prepared and tested by PharmaCyte’s contractor, Eurofins Lancaster Laboratories. The cells from the MCB will serve as the active pharmaceutical ingredient (API) in the company’s Cell-in-a Box capsules that will be used (together with low doses of the cancer prodrug ifosfamide) for the treatment of locally advanced, non-metastatic, inoperable pancreatic cancer (LAPC) in its planned clinical trial.

The comprehensive characterization studies include long-term stability of the cells, and stability of the potency of the cells as a therapeutic. All studies performed are required by the U.S. Food and Drug Administration (FDA).

PharmaCyte’s Chief Executive Officer, Kenneth L. Waggoner, elaborated on the significance of the studies saying, "PharmaCyte is complying with all of the FDA guidelines and recommendations for all cell tests and other recent studies with the 22P1G cells. Successful completion of these studies was a pre-requisite for the approval by the FDA for us to conduct a clinical trial in patients with LAPC. Our treatment is primarily dependent upon genetically engineered live-human cells that produce a particularly potent cytochrome P450 enzyme that can activate the chemotherapy prodrug ifosfamide (clone 22P1G cells).

"With each individual batch, these cells must be stable for the long term, and the properties of the 22P1G cells must remain consistent from batch to batch. The newly completed studies provide evidence that both requirements have been met. Our pancreatic cancer treatment utilizes 22P1G cells that have been encapsulated using the Cell-in-a-Box technology. For treatment of LAPC patients, the capsules containing the cells are implanted near the pancreatic tumor so that a high local concentration of the cancer-killing ifosfamide metabolite is produced near the tumor."

On June 13, 2018 Sun BioPharma, Inc. (OTCQB:SNBP) and its wholly owned subsidiary, Sun BioPharma Australia Pty Ltd, a clinical stage biopharmaceutical company developing disruptive therapeutics for the treatment of patients with pancreatic diseases, reported that on June 4, 2018 the first patients were enrolled in a Phase 1a/1b study of SBP-101 in combination with gemcitabine and nabpaclitaxel for front-line treatment of patients with metastatic pancreatic ductal adenocarcinoma (PDA) (Press release, Sun BioPharma, JUN 13, 2018, View Source [SID1234527299]). Sun BioPharma Australia Pty Ltd, is the sponsor of this study. The Phase 1a portion of this study will treat up to 18 PDA patients in three cohorts in order to determine a recommended dose of SBP-101 to be given in combination with standard treatment. The Phase 1b portion will be an expansion at the recommended dose of SBP-101, and will guide SBP-101’s subsequent development for patients with PDA. This multi-center, front-line study has 3 sites in Australia, The Austin Health Cancer Trials Centre in Melbourne, The Adelaide Cancer Centre in Adelaide, The Blacktown Cancer and Haematology Centre in Sydney and one site in the United States, The University of Florida Health Cancer Center in Gainesville, Florida. The first patients have been enrolled at the Adelaide Cancer Centre in Adelaide, Australia under the direction of Associate Professor Dusan Kotasek and at the University of Florida Health Cancer Center in Gainesville, Florida under the direction of Thomas J. George, MD, F.A.C.P.

Dr. Kotasek received his medical degree at the University of Adelaide and specialty training in Haemotology and Oncology at The Queen Elizabeth Hospital followed by a Fellowship at the University of Minnesota, in Minneapolis, MN, USA. A Co-Founder of the Adelaide Cancer Centre, Dr. Kotasek has published over 60 scientific papers in oncology, and he is one of Australia’s leading cancer clinical research experts. Dr. Kotasek, the Principal Investigator for this study at the Adelaide Cancer Centre commented, "Pancreatic cancer is a challenging disease with few significant options available with a meaningful impact on response rates and progression free survival. We are excited to participate in this clinical study, and to continue our evaluation of SBP-101 as front-line combination treatment for previously untreated patients with metastatic PDA."

Dr. George is a medical oncologist having graduated with honors from the University of Florida College of Medicine. He is the Director of the GI Oncology Program at the University of Florida and Associate Director of Clincial Investigation at the UF Health Cancer Center. He is the Principal Investigator for this study at the University of Florida Health Cancer Center and he commented, "We are extremely honored to be participating in this important study that was born from the discoveries made by Dr. Raymond Bergeron here at the University of Florida. Pancreatic cancer
requires us to think outside the box which is exactly what this treatment has the potential to offer our patients with PDA."

"Pancreatic cancer is a leading cause of cancer deaths in both Australia and the United States, currently being the 3rd most common cause of cancer deaths in the US. It represents a significant unmet medical need, with most patients having a poor prognosis and limited life expectancy," said Suzanne Gagnon, M.D., Chief Medical Officer at Sun BioPharma. "Our recently completed safety study in heavily pre-treated PDA patientssuggested SBP-101 could be a promising addition to current front-line treatment regimens. The Data Safety Monitoring Board, Principal
Investigators and our clinical team agreed to move directly to front-line for our second trial and we are excited to study SBP-101 in combination with standard of care chemotherapy for previously untreated metastatic PDA patients."

About SBP-101
SBP-101 is a first-in-class, proprietary, polyamine compound designed to exert therapeutic effects in a mechanism specific to the pancreas. Sun BioPharma originally licensed SBP-101 from the University of Florida Research Foundation in 2011. The molecule has been shown to be highly effective in preclinical studies of human pancreatic cancer models, demonstrating superior activity to existing FDA-approved chemotherapy agents. Combination therapy potential has also been shown for pancreatic cancer. SBP-101 is expected to differ from current pancreatic cancer
therapies in that it specifically targets the exocrine pancreas and has shown efficacy against primary and metastatic disease in animal models of human pancreatic cancer. Therefore management believes that SBP-101 may effectively treat both primary and metastatic pancreatic cancer, while leaving the insulin-producing islet cells and non-pancreatic tissue unharmed. The safety and metabolic profile demonstrated in our first-in-human safety study further supports
evaluation of the potential for additive or synergistic effects in combination with current standard pancreatic cancer treatment
