Hepatitis C results boost 2 firms

NEW YORK — Abbott Laboratories said Monday that its experimental hepatitis C drug regimen cured 99 percent of patients in a midstage study with the most common and hardest-to-treat type of the disease.

Patients who took a three-drug regimen and the drugs Ritonavir and ribavirin had undetectable virus levels after 12 weeks of treatment. The company says it observed a 93 percent cure rate in a group of patients who were not helped by other treatments.
