Autotaxin activity correlated significantly with tauro\u2010 and glyco\u2010conjugated cholic acid (CA) and chenodeoxycholic acid (CDCA), both at baseline and after GSK2330672. GSK2330672 significantly reduced autotaxin and all tauro\u2010 and glyco\u2010 conjugated BAs and increased faecal levels of CA (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0=\u00a00.048) and CDCA (\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0=\u00a00.027).
