- Efficacy Comparison: Patients treated with NAI+BCG were twice as likely to achieve a complete response (CR) compared to those receiving nadofaragene firadenovec-vncg, highlighting NAI+BCG's significant advantage in treating BCG-unresponsive non-muscle invasive bladder cancer (NMIBC), suggesting it may become a preferred treatment option.
- Response Duration: The median duration of CR for NAI+BCG was 22.1 months, significantly longer than the 9.7 months observed with nadofaragene, with a difference of 12.45 months, emphasizing the long-term efficacy of NAI+BCG and its potential impact on clinical decision-making.
- Surgery Risk Reduction: NAI+BCG reduced the risk of cystectomy by 60% compared to nadofaragene, providing a crucial treatment option for patients seeking bladder preservation, which holds significant clinical implications.
- Safety Advantages: NAI+BCG demonstrated a higher 12-month CR rate than TAR-200 (49.2% vs. 45.9%) and a statistically significant 68% reduction in treatment-related adverse events, indicating that NAI+BCG excels in both safety and efficacy, potentially enhancing its market acceptance.
