 filed an Investigational New Drug (IND) application with the United States Food and Drug Administration (“FDA”) to initiate a Phase I clinical trial assessing safety and feasibility of the dCellVax gene-silenced immune cell immunotherapy for treating patients with solid tumors that are metastatic or not able to be removed surgically. The proposed trial will recruit 25 patients with metastatic cancer and will involve 3 monthly injections of the dCellVax gene-silenced dendritic cell therapy. The trial is anticipated to cost $5,000,000 and last one year, with tumor assessment before therapy and at 6 and 12 months.

DiffronC: NR2F6 is a transcription factor that is present in many cells in the body, including immune cells but also highly expressed in certain solid tumors. NR2F6 normally acts as a brake on the ability of various immune cells from being activated and also allows tumor cells to keep growing. The Company has developed a proprietary drug that is based on shRNA technology, which prevents NR2F6 from being expressed. By inhibiting the expression of NR2F6, immune cells that are treated with the NR2F6-blocking shRNA become highly activated and can efficiently kill tumors and tumors that have NR2F6 suppressed begin to differentiate.. We are currently in pre-clinical testing of this drug to optimize its delivery in vivo. The two main risks associated with this drug development plan is that the NR2F6 siRNA is not effective at inhibiting NR2F6 expression or that this inhibition will not result in immune cells with enhanced tumoricidal activity.

DuraCar: DuraCar is a new cellular therapy being developed by the Company. It is comprised of CAR-T cells which contain an shRNA targeting the gene NR2F6. CAR-T cells are T cells (the lymphoid cells of the body that kill tumors) isolated from a cancer patient that have been modified by expressing a chimeric antigen receptor (CAR) which is specific for the patient’s tumor. These CAR-T cells are then re-infused back into the patient. The CAR-T cells then home in directly on the tumor because they have been given the tumor-specific address via the CAR. While CAR-T cells are very effective in treating leukemias, they are not effective at treating most solid tumors. The reason for this is believed to be that the CAR-T cells are “turned-off” by the physical environment surround solid tumors. By inhibiting NR2F6, we
