GNE-616 is a highly potent, metabolically stable, orally bioavailable, and subtype selective Nav1.7 inhibitor (Ki of 0.79 nM and Kd of 0.38 nM for hNav1.7) for the treatment of chronic pain. GNE-616 shows >1000 nM Kd and >2500-fold selectivity over hNav1.1, hNav1.3, hNav1.4, and hNav1.5. Selectivity over hNav1.2 and hNav1.6 is more modest at 31- and 73-fold, respectively[1]. Ki: 0.79 nM (hNav1.7)[1]Kd: 0.38 nM (hNav1.7), 12 nM (hNav1.2), 29 nM (hNav1.6)[1]
Site-directed mutagenesis is critical for the isoform selectivity profile of GNE-616 (hNav1.7, Kd: Y1537s/W1538=170±67 nM, V1541=3.9±1.1 nM, Y1537s/W1538/V1541=790±350 nM)[1].
GNE-616 shows robust activity in a Nav1.7-dependent inherited erythromelalgia (IEM) PK/PD model with an EC50 of 740 nM and EC50,u of 9.6 nM[1].

Structure- and Ligand-Based Discovery of Chromane Arylsulfonamide Nav1.7 Inhibitors for the Treatment of Chronic Pain
J Med Chem 2019 Apr 25;62(8):4091-4109.PMID:30943032DOI:10.1021/acs.jmedchem.9b00141
Using structure- and ligand-based design principles, a novel series of piperidyl chromane arylsulfonamide Nav1.7 inhibitors was discovered. Early optimization focused on improvement of potency through refinement of the low energy ligand conformation and mitigation of high in vivo clearance. An in vitro hepatotoxicity hazard was identified and resolved through optimization of lipophilicity and lipophilic ligand efficiency to arrive at GNE-616 (24), a highly potent, metabolically stable, subtype selective inhibitor of Nav1.7. Compound 24 showed a robust PK/PD response in a Nav1.7-dependent mouse model, and site-directed mutagenesis was used to identify residues critical for the isoform selectivity profile of 24.
