Description: Batefenterol (formerly known as GSK961081 and TD-5959) is a novel, potent and selective muscarinic receptor antagonist and β2-adrenoceptor agonist; it displays high affinity for hM2, hM3 muscarinic and hβ2-adrenoceptor with Ki values of 1.4, 1.3 and 3.7 nM, respectively. In a phase 2b trial, batefenterol produced statistical and clinically significant differences compared to placebo and numerically greater improvements in the primary end point of trough FEV1 compared to salmeterol after 4 weeks of dosing in patients with moderate to severe chronic obstructive pulmonary disease (COPD).
