Participants who have previously been treated with a T790M inhibitor (i.e., osimertinib) and have progressed will not require T790M testing (the 28-day screening period could be extended to allow for confirmation of the T790M status.

16. Participants must have completed afatinib and/or gefitinib treatment at least 1 week before the first dose of bemcentinib.
17. Toxicity from other prior therapy has resolved to ≤ Grade 1 (previous treatment with bevacizumab and other licensed antibody therapies is permitted).
18. Participants who have an activating EGFR mutation may have up to 4 lines of previous treatment in the advanced setting. Additional chemotherapy may also have been given for treatment of limited stage disease in the adjuvant setting provided this was completed at least 6 months prior to study treatment.
Additional Inclusion Criteria for Arm C
19. Known EGFR mutation status:
20. Presence of an activating EGFR mutation (including exon 19 deletion or exon 21 \[L858R\] substitution mutation or other rearrangement of the EGFR gene).
21. Disease that is measurable or evaluable according to RECIST Version 1.1.
22. Is currently receiving erlotinib for NSCLC and will have received ≥12 weeks' treatment at the time of the first dose of bemcentinib (Cycle 1, Day 1).
23. Have erlotinib-related toxicities that are well controlled and \<Grade 3 in severity the time of the first dose of bemcentinib (Cycle 1, Day 1).
24. No prior treatment for advanced NSCLC except erlotinib and/or previous surgery (participants who have received treatment for their NSCLC while awaiting confirmation of EGFR status, may be eligible to participate and the inclusion of such participants should be discussed with the Medical Monitor).
