Assuming BEV behaves as in historical data, VB111 would achieve a significant survival improvement vs BEV (ca 30-32% vs 20-18%) at the 189th event, even if it happens at the end September or the end of October, ie at 14th or 15th month as weighted avg. But it would underperform ph2.
On the contrary, if the 189th event happens at the end of November or the end of December, VB111 would not only show a significant survival improvement vs BEV (basically doubling survival rates at the 16-17th months , ie 33%-34% vs 16%-17%), but also greatly improving ph2 results (since quite a few deaths happened during those mont
