Vertex Announces Collaboration with Janssen To Initiate Phase 2 All-Oral Study of VX-135 and Simeprevir (TMC435) for the Treatment of Hepatitis C
-Companies to evaluate two-drug combination of Vertex's investigational nucleotide analogue VX-135 and Janssen's investigational protease inhibitor simeprevir (TMC435)-
-Phase 2 proof-of-concept study to begin in early 2013 to evaluate safety, tolerability and viral cure rates of 12-week treatment regimen-
"This collaboration is an important step forward in our commitment to
develop new all-oral treatment regimens for people with hepatitis C —
both in collaboration with other companies like Janssen and with
medicines within our own pipeline," said
Clinical Development Plans
Vertex and Janssen expect to initiate a Phase 2 proof-of-concept study of VX-135 and simeprevir in early 2013, following the completion of a drug-drug interaction (DDI) study and pending discussions with regulatory authorities. Costs associated with the studies will be shared equally between the two companies. The goals of the study will be to evaluate safety, tolerability and viral cure rates (SVR12; undetectable hepatitis C virus 12 weeks after the end treatment) of multiple 12-week combination regimens of VX-135 and simeprevir, with and without ribavirin, in people who have chronic non-cirrhotic genotype 1 hepatitis C and have not previously been treated (treatment-naïve). Further clinical development activities beyond the Phase 2 proof-of-concept study are not covered as part of this collaboration. Additional information on the Phase 2 study will be provided upon initiation of the study.
VX-135 (ALS-2200) is a uridine nucleotide analogue pro-drug that appears
to have a high barrier to drug resistance based on in vitro
studies. It is designed to inhibit the replication of the hepatitis C
virus by acting on the NS5B polymerase. In vitro studies of the
compound showed antiviral activity across all genotypes, or forms, of
the hepatitis C virus, including genotypes more prevalent outside of
Earlier this year, Vertex announced the first 7-day viral kinetic data for VX-135. Based on these data, the company plans to initiate multiple all-oral, Phase 2 proof-of-concept studies, including a study of VX-135 and ribavirin and a study of VX-135 and telaprevir, the company's approved protease inhibitor marketed as INCIVEK for people with chronic genotype 1 hepatitis C. Vertex is on track to initiate the study of VX-135 in combination with ribavirin by the end of 2012, followed by the study with telaprevir in early 2013. The studies will evaluate safety, tolerability and viral cure rates (SVR12; undetectable hepatitis C virus 12 weeks after the end treatment) of 12-week combination regimens in people with chronic non-cirrhotic genotype 1 hepatitis C who have not previously been treated (treatment-naïve).

About Simeprevir (TMC435)
Simeprevir is a once-daily potent investigational hepatitis C protease
inhibitor in late Phase 3 clinical development being jointly developed
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.1 Chronic hepatitis C can lead to serious and life-threatening liver problems, including liver damage, cirrhosis, liver failure or liver cancer.1 Though many people with hepatitis C may not experience symptoms, others may have symptoms such as fatigue, fever, jaundice and abdominal pain.1
Unlike HIV and hepatitis B virus, chronic hepatitis C can be cured.2 However, approximately 60 percent of people do not achieve SVR,3,4,5 or viral cure,6 after treatment with 48 weeks of pegylated-interferon and ribavirin alone. If treatment is not successful and a person does not achieve a viral cure, they remain at an increased risk for progressive liver disease.7,8
More than 170 million people worldwide are chronically infected with
hepatitis C.6 In

IMPORTANT SAFETY INFORMATION FOR INCIVEK
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 should always be taken in combination with peginterferon alfa and ribavirin. 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. Patients must use two forms of effective birth control during treatment and for the 6 months after treatment with these medicines. Hormonal forms of birth control, including birth control pills, vaginal rings, implants or injections, 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.
INCIVEK can cause serious side effects including skin reactions, rash and anemia that can be severe. The most common side effects of INCIVEK include itching, nausea, diarrhea, vomiting, anal or rectal problems, 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 providers about any side effect that bothers them or doesn't go away.
