RE:Oncolytics Biotech® Reports Third Quarter 2024 Financial Res
September 14, 2024 - Oncolytics Biotech® Reports Favorable Results for BRACELET-1 Breast Cancer Study Reinforcing Path to Funding of a Registration-Enabling Study
Final BRACELET-1 Results
Final BRACELET-1 efficacy data were collected and analyzed two years after the last patient was enrolled as specified by the protocol. Results of the final BRACELET-1 analysis show that the median OS was not reached in the pelareorep + paclitaxel arm, as more than half of the patients in that arm remained alive at study end. In contrast, median OS for the paclitaxel monotherapy arm was 18.2 months, and the hazard ratio was 0.48 for pelareorep + paclitaxel vs. the paclitaxel monotherapy. Had study follow-up continued beyond two years, and patients survived only until the next planned visit (in four months), the median OS for patients in the pelareorep + paclitaxel arm would be 32.1 months. In accordance with these results, the two-year survival rate for patients in the pelareorep + paclitaxel arm was 64% compared to 33% for paclitaxel monotherapy patients. Additionally, the final median progression-free survival (PFS) for BRACELET-1 was 12.1 months in the pelareorep + paclitaxel arm vs. 6.4 months in the paclitaxel monotherapy arm, representing a 5.7-month benefit with a hazard ratio of 0.39.
Confirmed overall response rate (ORR) was 37.5% for pelareorep + paclitaxel and 13.3% for paclitaxel. As previously reported, ORRs at week 16 (the trial's primary endpoint) in the pelareorep + paclitaxel and paclitaxel monotherapy cohorts were 31% and 20%, respectively.
"The fact that the median overall survival was not reached because more than half the patients were still alive at the end of the study is a remarkable achievement for us," said Wayne Pisano, Interim CEO and Chair of Oncolytics' Board of Directors. "It shows just how promising pelareorep treatment can be for extending the lives of breast cancer patients. This is further exemplified by the near doubling of the 2-year survival rate for patients who received pelareorep combination therapy."
