Abstract Text

Intracranial efficacy of first-line crizotinib versus chemotherapy was compared prospectively in the phase III PROFILE 1014 study in ALK-positive non-small-cell lung cancer.Patients were randomly assigned to receive crizotinib (250 mg twice daily; n = 172) or chemotherapy (pemetrexed 500 mg/m(2) plus cisplatin 75 mg/m(2) or carboplatin at area under the curve 5 to 6, every 3 weeks for ≤ six cycles; n = 171). Patients with stable treated brain metastases (tBM) were eligible. Intracranial efficacy was assessed at baseline and every 6 or 12 weeks in patients with or without known brain metastases (BM), respectively; intracranial time to tumor progression (IC-TTP; per protocol) and intracranial disease control rate (IC-DCR; post hoc) were measured. The intent-to-treat population was also assessed.Of 343 patients in the intent-to-treat population, 23% had tBM at baseline. A nonsignificant IC-TTP improvement was observed with crizotinib in the intent-to-treat population (hazard ratio [HR], 0.60; P = .069), patients with tBM (HR, 0.45; P = .063), and patients without BM (HR, 0.69; P = .323). Among patients with tBM, IC-DCR was significantly higher with crizotinib versus chemotherapy at 12 weeks (85% v 45%, respectively; P < .001) and 24 weeks (56% v 25%, respectively; P = .006). Progression-free survival was significantly longer with crizotinib versus chemotherapy in both subgroups (tBM present: HR, 0.40; P < .001; median, 9.0 v 4.0 months, respectively; BM absent: HR, 0.51; P < .001; median, 11.1 v 7.2 months, respectively) and in the intent-to-treat population (HR, 0.45; P < .001; median, 10.9 v 7.0 months, respectively).Compared with chemotherapy, crizotinib demonstrated a significantly higher IC-DCR in patients with tBM. Improvements in IC-TTP were not statistically significant in patients with or without tBM, although sensitivity to detect treatment differences in or between the two subgroups was low.

Filtering

Case insensitive filtering will display rows if any text in any cell matches the filter term
Use simple literal full or partial string matches
Separate multiple filter terms with a space. Any order may be used (i. e. a b c and c b a are equivalent )
Filtering will only apply to rows that are already loaded on the page. Filtering has no impact on query parameters.
Use quotes to match on a longer phrase with spaces (i.e. "mtor c1483f")

Sorting

Generally, the default sort order for tables is set to be first column ascending; however, specific tables may set a different default sort order.
Click on any column header arrows to sort by that column
Hold down the Shift key and click multiple columns to sort by more than one column. Be sure to set ascending or descending order for a given column before moving on to the next column.
