DURUISSEAUX et al. 2017

The OS with XALKORI in unselected ALK+ NSCLC patients was assessed.1​​​​​​​

Median OS of 89.6 months for patients receiving next-generation ALK inhibitors after progression on XALKORI was significantly longer than with XALKORI followed by other systemic therapies (28.2 months) or BSC (19.6 months) (p<0.001).1

Limitations of the analysis:1

The improved OS data may have been due to biases in patient selection, OR specific tumour biology and high sensitivity to ALK inhibition, rather than a direct effect of treatment strategies.
Patients receiving next-generation ALK inhibitors tended to be younger, more frequently exhibited PFS on XALKORI ≥median, more frequently received XALKORI beyond progressive disease, and more frequently exhibited cerebral progression than patients receiving subsequent drugs other than next-generation ALK inhibitors.

5.0% of patients received XALKORI in first line, 54.1% in second line and 40.9% in later lines of therapy (≥2).
Next-generation ALK inhibitors administered: 57 patients received ceritinib, 19 alectinib, 5 ceritinib then alectinib, 1 ceritinib then lorlatinib, 2 alectinib then ceritinib. Lorlatinib is an investigational compound.
The mean time from diagnosis of advanced disease to initiation of XALKORI was 13.9 months (95% CI: 12.4–15.5).

*Median duration of follow-up was 44.4 months (95% Ci: 40.6-47.5).

ALK inhibitors1

The survival rates reported here in a large population treated with crizotinib then next-generation ALK inhibitors could represent an interesting benchmark for ongoing clinical trials assessing how best to sequence the available ALK inhibitors.

ALKi, ALK inhibitor; BSC, best supportive care; PFS, progression-free survival.​​​​​​​
