Theravance (THRX) Higher After Compound Shows Clinical Significance
Theravance, Inc. (Nasdaq: THRX) is 13% higher in after-hours trading after the company announced the results of two studies in an ongoing Phase 2b clinical program to assess the efficacy and safety of the investigational bronchodilators GSK642444 ('444) and GSK159797 ('797), the lead long-acting Beta2 agonist compounds in the Beyond Advair collaboration with GlaxoSmithKline (NYSE: GSK).
In the studies, '444, a GSK-discovered compound, and '797, a Theravance-discovered compound, each given once daily, achieved clinically significant increases in bronchodilation at least equivalent to salmeterol given twice daily. Both compounds exhibited a pharmacodynamic profile similar to other inhaled LABAs, with little impact on heart rate.
