We know from the clinical trials that the second-line chemotherapy, carboplatin-based chemotherapy has a limited efficacy, but we don’t have a lot of data from the real world. So we have run a multicentric study showing that one-third of patients respond to carboplatin and pemetrexed after osimertinib, the PFS is consistent with the previously presented data in clinical trials, but the overall survival is shorter, about nine months, the median overall survival, which is not surprising considering that the characteristics of those patients are not the same as those recruited for clinical trials...

They are less fit with a higher incidence of brain metastasis and therefore the survival is shorter.
