1 Co-administration of rifampicin in Beagle dogs reduced the fecal recovery of almonertinib and HAS-719, and markedly increased the levels of metabolites derived from further metabolism of HAS-719, which was consistent with human plasma data, suggesting that although rifampicin was also a potent inducer of P-gp, the pharmacokinetic alternation of HAS-719 was mainly due to its further metabolism but not excretion changes. Rifampin phosphoglycolate phosphatase Homo sapiens
