Anupam Rama's questions to CytomX Therapeutics (CTMX) leadership • Q2 2025
Question
Anupam Rama from JPMorgan Chase & Co. asked about the expectations for the preliminary CX-801 monotherapy data in Q4 and any potential risks of overlapping toxicity with the KEYTRUDA combination.
Answer
Sean A. McCarthy, Chairman & CEO, explained that the Q4 update will focus on translational data from paired tumor biopsies in a small number of monotherapy patients, looking for evidence of target engagement and modulation of the tumor microenvironment, such as PD-L1 upregulation. He noted that the combination of interferon and KEYTRUDA has shown powerful activity previously, and CytomX's masking technology aims to mitigate the known toxicity issues.
