📫 Interim results of #Sunrise4 are released @TheLancetOncol
Neoadjuvant #TAR200 + cetrelimab vs cetrelimab monotherapy in pts with #MIBC
✅ TAR200+CET: pCR 42%, Major path Response 60%
✅ in cT2 pts baseline: pCR 48%
✅ TAR200 exposure-response association: pCR 50% if TAR200x4 full cycles
Can we cure selected pts with MIBC with intravesical Rx + single agent IO?
Future: is there a way to avoid #radicalcystectomy by consolidating Response with TAR200 in selected pts?
Primary results with full biomarker results are awaited
