inconclusive
  • inconclusive 11 % increase in iDFS (PE)
At the final analysis, the addition of atezo to adjuvant anthracycline- and taxane-based chemo did not improve iDFS in the ITT population of stage II-III TNBC or in any of the subgroups interrogated. Safety data remain consistent with the known profile of atezo in early TNBC.

inconclusive
    no statistically significant result
The addition of atezolizumab to nab-paclitaxel and carboplatin did not significantly increase the rate of pCR in women with TNBC. In multivariate analysis, the presence of PD-L1 expression was the most significant factor influencing the rate of pCR (OR 2.08).
