Cytokinetics Inc.'s heart-failure treatment drug will advance to late-stage clinical development, the company said Thursday, after spending roughly a decade in the middle stage.

The decision to proceed to Phase III development, which is expected to happen during the fourth quarter, follows results announced in 2015 from a study that showed the drug, omecamtiv mecarbil, demonstrated improvements in some measures of cardiac function.

Cytokinetics's partner Amgen Inc. holds an exclusive license world-wide to develop and commercialize the drug. The Phase III trial will be conducted by Amgen in collaboration with Cytokinetics.

Shares of Cytokinetics fell 7.8% to $11.13 in morning trading in New York.

Omecamtiv mecarbil is a heart failure treatment that acts on the heart muscle to lengthen its contraction time and improve cardiac output. It is being developed for patients with chronic heart failure.
