FDA Approves Genentech’s Tecentriq for ctDNA-Guided Bladder Cancer Treatment
Event summary
- FDA approved Genentech’s Tecentriq for adjuvant muscle-invasive bladder cancer treatment guided by ctDNA testing.
- Approval based on Phase III IMvigor011 study showing 36% reduction in disease recurrence and 41% reduction in death risk.
- Natera’s Signatera™ CDx assay used as companion diagnostic to identify ctDNA MRD.
- First ctDNA-guided regulatory approval for bladder cancer, setting precedent for other cancer types.
The big picture
This approval marks a significant milestone in precision oncology, combining immunotherapy with molecular residual disease detection. The ctDNA-guided approach could become a new standard for adjuvant cancer treatment, potentially expanding beyond bladder cancer. Genentech’s success here positions it as a leader in personalized cancer care, with Roche benefiting from the innovation.
