I think both updates have many positives & negatives, the biggest negative is the one miti has touched on - MES:-
1. recently completed the largest MES study conducted on PRCC patients, which was aimed at developing a more comprehensive understanding of the role of MET-driven disease in PRCC.
2. Sutent® (sunitinib) (VEGFR TKI) in first-line PRCC was effective, providing similar tumor control across MET positive and negative patients
3. Incidence of MET positive PRCC patients was lower than previous scientific publications and the savolitinib US Phase II study;
4. ? Incidence of MET positive PRCC patients was lower than previous scientific publications and the savolitinib US Phase II study;
As a result, the savolitinib registration strategy for PRCC is being reassessed, Enrollment in the SAVOIR study has been suspended.
It appears that in PRCC Savolitinib offers no advantage over Sutent which is contrary to what was previously expected
