Summary of varied generation ALK-TKI drugs recommended for NSCLC treatment

DrugMonth & year of approvalCircumstantial efficacy screenedGeneration stage
CrizotinibAugust 2011ALK metastatic tumorsFirst
CertinibApril 2014ALK metastatic tumorsSecond
AlectinibDecember 2015Progressed ALK metastatic tumors, exhibiting resistance to crizotinibSecond
November 2017ALK metastasis
BrigatinibApril 2017Progressed ALK metastatic tumors, displaying resistance to crizotinibSecond
EnsartinibCould not be authentically tracedExhibited 52% ORR in a phase II trial. A phase III trial found ensartinib better than crizotinib in systemic and intracranial diseases. ALK resistance were majorly due to G1269A, G1202R & E1210K mutationsSecond
LorlatinibNovember 2018ALK metastatic tumors treated with alectinib or certinib or crizotinib & at least one more ALK inhibitorThird
TPX-0131Currently being investigatedA compact macrocyclic inhibitor that fits well entirely in the ATP binding pocket. Efficient against compound mutations G1202R + L1198F, G1202R + L1196M, L1196M + L1198F, and G1202R + C1156FFourth
NVL-655Currently being investigatedA brain penetrant small molecule inhibitor with significant potential against solvent drug resistance mutations, viz. G1202R, G1202R + L1196M and G1202R + G12269AFourth
