Naureen Quibria's questions to Immunocore Holdings PLC (IMCR) leadership • Q2 2024
Question
Naureen Quibria of Capital One Securities asked how to best track response for the upcoming PRAME results at ESMO, and inquired about the prevalence of PRAME versus folate receptor in ovarian cancer and their potential overlap.
Answer
David Berman, Head of R&D, suggested that while treatment beyond progression is an indicator, disease control rate (DCR) is a very good metric for predicting progression-free survival (PFS) with brenetafusp. Mohammed Dar, an executive, stated PRAME prevalence is 80-90% in ovarian cancer, versus 35-40% for folate receptor. David Berman added that PRAME expression is likely independent of folate receptor status, though exact overlap data is unavailable.
