Description:

WARNING: This product is for research use only, not for human or veterinary use.

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.

More Info
ALK is a proto-oncogene that encodes the receptor tyrosine kinase ALK, which can be aberrantly activated by gene rearrangement or point mutation to drive tumor cell proliferation, survival, and metastasis. In advanced non-small cell lung cancer (NSCLC), ALK rearrangements are detected in about 4% of patients; at the time of diagnosis, 30% to 40% of these patients present with accompanying central nervous system (CNS) metastases. Brain-penetrant tyrosine kinase inhibitors (TKIs) alectinib, brigatinib, ceritinib, and lorlatinib are FDA-approved treatments for ALK-positive NSCLC; however, durability of response to these treatments has been limited in many cases by the emergence of mutations in ALK that confer resistance. A major resistance mutation to alectinib, brigatinib, and ceritinib is the ALK G1202R solvent front mutation. Although patients with tumors harboring the ALK G1202R mutation have responded to lorlatinib, many have subsequently relapsed by emergence of ALK compound mutations, such as G1202R/L1196M and G1202R/G1269A. Novel ALK inhibitor NUV-655 (NVL-655) was designed for broader coverage of ALK resistance mutations, activity in the CNS, and selectivity over structurally related tropomyosin receptor kinase B (TRKB). Avoiding TRKB inhibition is preferred, as CNS adverse events associated with TRKB inhibition have been reported for brain-penetrant TKIs
Biological target:
Neladalkib is an investigational drug targeting the anaplastic lymphoma kinase (ALK) receptor tyrosine kinase. It is specifically designed to inhibit ALK, including its resistant mutant forms, and is utilized in the treatment of ALK-positive cancers, such as non-small cell lung cancer (NSCLC). Neladalkib's development aims to address limitations of existing ALK inhibitors by targeting a broader range of ALK mutations and potentially offering enhanced efficacy and selectivity.
In vitro activity:
In vivo activity:
1. In vivo studies of NVL-655 demonstrate its effectiveness in targeting ALK-positive non-small cell lung cancer (NSCLC) with resistance mutations, including G1202R, G1202R/L1196M, and G1202R/G1269A. NVL-655 was well-tolerated and showed promising tumor regression in xenograft models, with effective brain penetration and minimal inhibition of the TRKB kinase, reducing potential CNS-related side effects. Its selectivity and activity against challenging ALK mutations highlight its potential as a valuable treatment option for patients with resistant ALK-positive NSCLC. Reference: Henry E.
