Bristol-Myers Squibb Company announced results from the Phase 2b EMERGE clinical trial, in which treatment with the investigational compound PEG-Interferon lambda and ribavirin achieved higher rates of rapid virologic response (RVR) in genotypes 1, 2, 3, and 4, and complete early virologic response (cEVR) in genotypes 1 and 4 than the standard regimen of PEG-Interferon alfa and ribavirin in treatment-naïve patients chronically infected with hepatitis C (HCV). In this study, there were fewer flu-like and musculoskeletal symptoms and cytopenia, as well as fewer interferon and ribavirin dose reductions for anemia in the PEG-Interferon lambda arms up to 12 weeks. Rates of serious adverse events, depression and other common adverse events (incidence ?10%) were similar across treatment arms up to week 12.
“There is a significant unmet medical need for more therapies that can benefit more hepatitis C patients. This is especially true for patients with HCV genotypes 1 and 4, who generally have lower response rates to treatment with PEG-Interferon alfa and ribavirin than patients with other genotypes,” said Stefan Zeuzem, MD, chief of the department of medicine and professor of medicine at the Johann Wolfgang Goethe University Hospital in Frankfurt, Germany. “The EMERGE study results demonstrate that PEG-Interferon lambda may have the potential to help address this unmet need, and support further studies of this new type of investigational interferon.”
PEG-Interferon lambda is the first investigational type III interferon. Interferon lambda mediates antiviral activity through a receptor that is distinct from that used by interferon alfa and is present on fewer cell types within the tissues of the body. This restricted distribution of the interferon lambda receptor offers the potential for more targeted delivery of interferon therapy.
