From Vir Biotechnology: Marianne De Backer on Immuno-Oncology, Hepatitis Delta, and Biotech Turnarounds · · IDEA Pharma
“So what happened post the covid pandemic actually is that as you know the sars co v2 viruses the you know evolved v new variants came up and so trophic map was no longer active and so that meant that the company went from having like a billion dollar in revenue in one year to almost having no revenue the next year. So that is something that very few companies survive these kind of very drastic impact on your income. And so I was brought in exactly at that time when that was happening to sort of think about what you know the company could be doing strategically going forward. And so I joined in April of 2023 and I have since then been building the company, you know, building on its existing strengths of protein engineering and being really good at coming up with antibbody therapeutics. Also understanding how the immune system, the human immune system fights infections, really building upon that, but then really pivoting the company into immunoncology and specifically immunoncology for solid tumors.”
