Frequently asked questions about RO5024048

What is RO5024048 used for?

RO5024048 is an investigational small molecule being studied for the treatment of chronic Hepatitis C. It was evaluated in combination with other antiviral agents, including danoprevir and ribavirin, in patients with genotype 1 chronic Hepatitis C, including those who were treatment-naïve or had previously not responded to interferon-based therapy.

Who makes RO5024048?

RO5024048 is being developed by Roche Holding AG, which trades under the ticker RHHBY. The drug is an investigational small molecule and has not been approved by regulatory authorities.

What phase is RO5024048 in?

RO5024048 has completed Phase 1 and Phase 2 clinical trials. All five trials listed for the drug are completed, with no active trials currently ongoing. The drug remains investigational and has not received regulatory approval.

What clinical trials is RO5024048 in?

RO5024048 has been studied in several completed clinical trials, including NCT00801255, NCT01278134, NCT01483742, and NCT01628094. These trials evaluated the drug in combination with other Hepatitis C treatments in patients with chronic genotype 1 infection, including those with compensated cirrhosis.

How does RO5024048 work?

RO5024048 is an HCV polymerase inhibitor. It works by targeting the Hepatitis C virus polymerase enzyme, which is essential for viral replication. By inhibiting this enzyme, the drug aims to reduce viral load in patients with chronic Hepatitis C.

Is RO5024048 the same as danoprevir?

No, RO5024048 is not the same as danoprevir. RO5024048 is an HCV polymerase inhibitor, while danoprevir (also known as RO5190591) is an HCV protease inhibitor. In clinical trials, the two drugs were studied in combination with each other, along with other agents such as ritonavir and ribavirin.
