Neladalkib, also known as NVL-655, and NUV-655, is a selective, brain-penetrant ALK inhibitor with antitumor activity against the lorlatinib-resistant G1202R/L1196M compound mutation. NUV-655 (NVL-655) inhibited the kinase activity of ALK and ALK G1202R/L1196M with Kiapp < 5 nM in the presence of 1 mM ATP and with selectivity over TRKB. Across a panel of 335 wild-type kinases, NUV-655 (NVL-655) inhibited only 5 other kinases by >50% within 10-fold of its IC50 for ALK. NUV-655 (NVL-655) also selectively inhibited ALK in cells. It inhibited the growth of Ba/F3 cells driven by expression of EML4-ALK variant 1 (v1) with either wild-type kinase domain or drug-resistance mutations G1202R, G1202R/L1196M, or G1202R/G1269A at IC50 values < 10 nM and with selectivity over TRKB. In vivo, NUV-655 (NVL-655) induced regression at well-tolerated doses in a Ba/F3 EML4-ALKv1 G1202R/L1196M xenograft model. Furthermore, NUV-655 (NVL-655) demonstrated brain penetrance in rodent pharmacokinetic studies.
