- Interim analysis of the Phase 3b CONCISE study showed SVR12 rates of 87 percent with 12 total weeks of treatment and 97 percent with 24 total weeks of treatment among people who achieved RVR and completed 12 weeks of treatment -
This study includes people with genotype 1 chronic HCV who were new to
treatment or who had relapsed after at least one prior course of
treatment with pegylated-interferon and ribavirin alone. Approximately
one-third of people with hepatitis C have the ‘CC' genotype, which has
been associated with higher sustained viral response (SVR, or viral
cure) rates and faster response to interferon-based treatment. The
safety profile of telaprevir combination therapy observed in the CONCISE
study through the time of the interim analysis was similar to that seen
in previously reported clinical trials. The interim results of this
study will be presented at the 48th Annual Meeting of the

CONCISE is a randomized, placebo-controlled, global, multi-center Phase 3b study designed to evaluate the safety and efficacy of a 12-week regimen of telaprevir tablets in combination with pegylated-interferon and ribavirin in people with genotype 1 chronic HCV infection who have the IL28B CC genotype. In this study, telaprevir was dosed as three 375mg tablets twice daily. The study includes 239 people with hepatitis C who are new to treatment as well as those who relapsed after at least one prior course of treatment with pegylated-interferon and ribavirin alone. The primary endpoint of the study is the proportion of randomized people who achieve a sustained viral response (HCV RNA < lower limit of quantification) 12 weeks after the last planned dose of study drug (SVR12). All study participants were assigned to receive telaprevir in combination with pegylated-interferon and ribavirin for 12 weeks. People who continued all study drugs for 12 weeks and achieved a rapid viral response to treatment (measured as undetectable HCV RNA at week 4) were randomized 2:1 to receive no further treatment or an additional 12 weeks of pegylated-interferon and ribavirin alone. People who did not achieve a rapid viral response or who did not continue all study drugs for 12 weeks were assigned a total pegylated-interferon and ribavirin treatment duration of 24 or 48 weeks based on virologic response.
INCIVEK® (telaprevir) tablets is an oral medicine that
acts directly on the hepatitis C virus protease, an enzyme essential for
viral replication. INCIVEK has been prescribed to more than 60,000
In Phase 3 clinical studies, 79 percent of people who had not previously been treated for HCV achieved a viral cure following treatment with INCIVEK combination therapy, compared with 46 percent of those who received pegylated-interferon and ribavirin (P/R) alone. Among people who were treated previously but did not achieve a viral cure, in the Phase 3 studies: 86 percent of relapsers achieved a viral cure with INCIVEK combination therapy compared to 22 percent with P/R alone; 59 percent of partial responders achieved a viral cure compared with 15 percent with P/R alone; and 32 percent of null responders achieved a viral cure compared with 5 percent with P/R alone. In addition, many people are eligible to complete treatment with INCIVEK combination therapy in 24 weeks — half the time required for treatment with P/R alone.

IMPORTANT SAFETY INFORMATION
INCIVEK® (telaprevir) is a prescription medicine used with the medicines peginterferon alfa and ribavirin to treat chronic (lasting a long time) hepatitis C genotype 1 infection in adults with stable liver problems, who have not been treated before or who have failed previous treatment. It is not known if INCIVEK is safe and effective in children under 18 years of age.
Important Safety Information
INCIVEK® (telaprevir) should always be used in combination with peginterferon alfa and ribavirin. INCIVEK combination treatment may cause serious side effects including skin rash and serious skin reactions, anemia (low red blood cell count) that can be severe, and birth defects or death of an unborn baby.
Skin rashes are common with INCIVEK combination treatment. Sometimes these skin rashes and other skin reactions can become serious, require treatment in a hospital, and may lead to death. Patients should call their healthcare provider right away if they develop any skin changes during treatment with INCIVEK. Their healthcare provider will decide if they need treatment or if they need to stop INCIVEK or any of their other medicines. Patients should not stop taking INCIVEK combination treatment without talking with their healthcare provider first.
Patients' healthcare providers will do blood tests regularly to check for anemia. If anemia is severe, the healthcare providers may tell them to stop taking INCIVEK.
INCIVEK combined with peginterferon alfa and ribavirin may cause birth defects or death of an unborn baby. Therefore, a patient should not take INCIVEK combination treatment if she is pregnant or may become pregnant, or if he is a man with a sexual partner who is pregnant. Females who can become pregnant and females whose male partner takes these medicines must have a negative pregnancy test before starting treatment, every month during treatment, and for 6 months after treatment ends. Patients must use two forms of effective birth control during treatment and for 6 months after all treatment has ended. These two forms of birth control should not contain hormones, as these may not work during treatment with INCIVEK.
INCIVEK and other medicines can affect each other and can also cause side effects that can be serious or life-threatening. There are certain medicines patients cannot take with INCIVEK combination treatment. Patients should tell their healthcare providers about all the medicines they take, including prescription and non-prescription medicines, vitamins and herbal supplements.
The most common side effects of INCIVEK combination treatment include itching, nausea, diarrhea, vomiting, anal or rectal problems (including hemorrhoids, discomfort , burning or itching around or near the anus), taste changes and tiredness. There are other possible side effects of INCIVEK, and side effects associated with peginterferon alfa and ribavirin also apply to INCIVEK combination treatment. Patients should tell their healthcare provider about any side effect that bothers them or doesn't go away.

About Hepatitis C
Hepatitis C is a serious liver disease caused by the hepatitis C virus, which is spread through direct contact with the blood of infected people and ultimately affects the liver.2 Chronic hepatitis C can lead to serious and life-threatening liver problems, including liver damage, cirrhosis, liver failure or liver cancer.2 Though many people with hepatitis C may not experience symptoms, others may have symptoms such as fatigue, fever, jaundice and abdominal pain.2 Unlike HIV and hepatitis B virus, chronic hepatitis C can be cured.3 If treatment is not successful and a person does not achieve a viral cure, they remain at an increased risk for progressive liver disease.4,5
More than 170 million people worldwide are chronically infected with
hepatitis C.6 In
