$CBIS Positive Cannabinoid Testing Data

GenePro® is an investigational DNA immunotherapy sponsored by IGXBio and would be considered a biologic. The Cannabis Science partnership is working to identify and develop agonist cannabinoids and IGXBio’s GenePro®.

GenePro® is a deoxyribonucleic acid (DNA) plasmid vaccine expressing simian immunodeficiency virus (SIV) and human immunodeficiency virus (HIV) proteins, which is administered by electroporation (EP). This FDA IND supports a biologic and device combination product.

HIV uses our immune system to infect healthy immunogenic cells and increase the opportunity of these cells to spread. HIV-1 proteins (gp120, Tat — the transactivator of transcription, Vpr, and Nef) are released from infected cells throughout the course of infection and create an ongoing HIV disease burden in a number of tissues, including the central nervous system (CNS), resulting in toxicity and damage, regardless of ART.

A substantial number of individuals with HIV disease suffer brain impairment such as HIV-1 associated cognitive impairment (HAND) and dementia. Many standard anti-retroviral drugs cannot cross the blood-brain barrier (BBB) and therefore they have no effect on HIV infection in the brain.

“To further cement our foothold in the substantial pharmaceutical drug development industry, we expect our IGXBio, GenePro® drug development program to be a major pharmaceutical success. Program specific details are underway and we will update progress and results as they come in,” stated Dr. Allen Herman, Cannabis Science Inc., Chief Medical Officer (CMO).
