Histogen, Inc. and Wylde, LLC Form Joint Venture

Pancreatic tumor inhibition on chorioallantoic membrane (TUMCAM). Pancreatic cancer is the fourth leading cause of cancer deaths among men and women, responsible for 6% of all cancer-related deaths.

The next generation of cancer treatment will have cell-signaling at its core, be beneficial in combination with existing therapies as well as stand alone, and provide an option to patients who currently have none.

Histogen Inc., a regenerative medicine company developing solutions based on the products of cells grown under simulated embryonic conditions, has partnered with Southern California medical device group Wylde, LLC to create Histogen Oncology. This joint venture will focus on the development of unique cell-derived materials for cancer applications.

Under this joint venture, Histogen Oncology has acquired exclusive rights to Histogen’s human multipotent cell conditioned media (CCM) and extracellular matrix (ECM) materials, as well as their derivatives, for oncology applications throughout North America. Histogen Oncology’s initial clinical focus is pancreatic cancer, a highly treatment-resistant cancer in which a sub-fraction of the CCM has shown substantial preclinical promise.    

“We have been very impressed with the results of Histogen’s preliminary oncology work, not only because of the significant survival benefit but also because it is a naturally-derived material that is showing no toxicity,” said Wiggins of Wylde, LLC. “There are so many patients out there who are not candidates for existing therapies due to the toxic nature of available drugs. This is particularly true in pancreatic cancer, where 80% of people diagnosed already have stage four disease.”

In post-resection nude mouse models, intravenous treatment with the CCM sub-fraction resulted in prolonged survival by more than three fold in a majority of treated animals. In non-resection models, more than 50% of treated mice lived twice as long as the control. These results point to a potentially significant outcome for pancreatic cancer patients, and Histogen Oncology intends to progress the material toward a Phase I clinical trial for no-option pancreatic cancer patients in the coming 18 months.

Research on the mechanism responsible for cancer cell inhibition by the CCM shows the upregulation of Caspase 9 and cleaved Caspase 3, which causes cancer cells to enter apoptosis, or programmed cell death.

“The activity of the CCM sub-fraction is unique in a number of ways. Whereas most cancer therapies target rapidly dividing cells but not cancer stem cells, the inhibitory effect of this material is seen in malignant cells and circulating tumor cells as well,” said Dr. Gail Naughton, CEO and Chairman of the Board of Histogen, Inc. “In addition, the activity is selective for malignant cells, supporting the proliferation of human dermal fibroblasts, embryonic stem cells and mesenchymal stem cells, while inhibiting tumor growth.”

Histogen Oncology will be supported by Histogen’s research group and funded by Wylde, LLC., made up of experts from the surgery and medical device industries. The creation of this joint venture allows for dedicated development of the CCM sub-fraction as a cancer treatment, as Histogen continues to allocate resources to the Company’s revenue-generating aesthetic and promising therapeutic programs.

"We are extremely excited to fuel and push the next stage of development for this innovative and potentially life-saving therapy,” said Wiggins. “The next generation of cancer treatment will have cell-signaling at its core, be beneficial in combination with existing therapies as well as stand alone, and provide an option to patients who currently have none. We believe Histogen’s material has all of those characteristics and more.”

About Histogen
Histogen is a regenerative medicine company developing solutions based upon the products of cells grown under proprietary conditions that mimic the embryonic environment, including low oxygen and suspension. Through this unique technology process, newborn cells are encouraged to naturally produce the vital proteins and growth factors from which the Company has developed its rich product portfolio. Histogen's technology focuses on stimulating a patient's own stem cells by delivering a proprietary complex of multipotent human proteins that have been shown to support stem cell growth and differentiation.
