Trial Details

The company noted that the latest observation trended similarly to its Phase IIb trial results and hazard ratio, where the patients were treated, and breast cancer recurrences were reduced up to 80% compared to a 20-50% reduction in recurrence rate by other approved products.

“Despite these being preliminary results that will mature and can change with time, seeing a reduction in expected recurrence rates that is trending towards a low HR of 0.2, which represents an 80% reduction in recurrence rate, is very encouraging and which is why along with the similarly promising safety and immune response data to date, we will seek to continue to treat non-HLA-A*02 patients in a placebo controlled manner in the study," said CEO Snehal Patel.
