CDR3 develops stem cell-based immunotherapies to cure HPV-related cancers using chimeric antigen receptors or chronic viral infections using T cell receptors.
Today, we lack cures for most virus-related cancers and chronic viral infections, especially from human papillomavirus, or HPV, and cytomegalovirus, or CMV, which can be fatal for those with weakened immune systems. CDR3’s stem cell-based treatments target HPV-associated cancers, a $16.3B market in 2018 growing at 4.5% yearly, and chronic viral infections, a rapidly growing market estimated to reach $44.2B by 2026 — with chronic CMV alone a $1.2B market in 2020 growing at 12.3% yearly.
CDR3’s patented technology alters blood stem cells to add chimeric antigen receptors (CARs) or T cell receptors (TCRs) that enable the body’s natural defenses to target virus-associated cancers. These stem cells engraft in bone marrow and develop, normally and continuously, into T cells. Isolating a patient’s own cells and infusing the CAR/TCR gene therapy creates a permanent source of T cells expressing the CAR/TCR, avoiding the high cost and significant limitations of current T cell therapy approaches.
