5、the ability of ACC2 to compensate for ACC1inhibition. ND-646 inhibits dimerization of recombinant human ACC2 BC domain (hACC2-BC) under nativeconditions; hACC2-BC migrates as a dimer in its absence and a monomer in its presence. In cell freesystems, ND-646 inhibits enzymatic activity of recombinant

ND-646 at 25 mg/kg QD is ineffective at inhibiting tumor growth. However, ND-646administered at 25 mg/kg BID or 50 mg/kg QD significantly inhibits subcutaneous A5

ND-646 is well tolerated throughout the treatment period, with no significant weight loss occurring after chronicND-646 dosing, suggesting that the maximum tolerated dose (MTD) has not been reached.

Tumors treated with all doses of ND-646 have lost detection of P-ACC at 1 hr,demonstrating effective tumor penetration and acute ACC inhibition by ND-646.
