Why ArQule Inc is Down 12 Percent Tuesday (ARQL)

Zemanta Related Posts ThumbnailShares of ArQule (NASDAQ: ARQL) are down about 12 percent in early trading Tuesday after the company, along with its partner, Daiichi Sankyo, announced that in a Phase III trial of its cancer drug, tivantinib, the dosage will be reduced from 240 mg twice daily to 120 mg to address the observation of a higher incidence of neutropenia that wasn’t observed in the Phase II trial.

While not a major setback, the companies believe that the lower dosage will reduce the observed side effects but until data proves this to be true, investors will be concerned that the trials may not meet their primary endpoints.
