Empowered Patient Podcast Leveraging the Power of the Immune System to Fight Disease with Marianne De Backer Vir Biotechnology
Marianne De Backer is the CEO of Vir Biotechnology, a company developing treatments that harness the power of the immune system to fight serious infectious diseases and cancer. Vir Biotechnology’s current clinical trials include a registrational program in chronic hepatitis delta, a rare, often fatal liver disease, as well as two Phase 1 trials of PRO-XTEN™ dual-masked T-cell engagers (TCEs), one targeting HER-2 and the other targeting PSMA, each in heavily pre-treated cancer patients. TCEs have shown tremendous potential but have been limited due to toxicity challenges. The PRO-XTEN™ technology keeps the TCEs masked until they reach the tumor microenvironment, potentially mitigating the toxicity of TCEs and allowing them to unleash their tremendous potential to destroy cancer cells.
Marianne explains, “Vir Biotechnology is an immunology company, and that means that we are really developing treatments that take advantage of the power of basically the patient's own immune system to fight a variety of diseases. We have actually four clinical-stage programs in infectious disease and oncology, and a number of preclinical programs as well. And our most advanced program is to treat chronic hepatitis delta. That is actually a disease caused by a tiny virus, but it's causing liver cancer and is often fatal.”
“We have recently initiated our registrational phase 3 program. It's called ECLIPSE. We had previously shown some very compelling data with one of our regimens for treating this disease. We're really excited about progressing that program. And the rest of our clinical pipeline includes a series of so-called PRO-XTEN™ masked T-cell engagers, or in short, TCEs, for the treatment of metastatic solid tumors.”
