17 AXL-positive patients were radiologically evaluable, with 6 responses observed (35%), as opposed to 2 (15%) in the 13 radiologically evaluable AXL-negative patients. Of the 10 responders, 4 had a TPS <1% (2 AXL positive, 2 negative), 3 TPS 1-49% (2 AXL-positive, 1 unknown), 1 TPS >50% (1 AXL-positive); 2 did not have a PD-L1 status available (1 AXL-positive, 1 unknown)....Promising clinical activity has been seen, particularly in pts with AXL-positive disease and including patients with PD-L-negative tumours. Overall, bemcentinib in combination with pembrolizumab was well tolerated.
