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- Business Wire CAMBRIDGE, Mass. -- November 01, 2012 Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced that it has entered into a non-exclusive collaboration with Janssen Pharmaceuticals, Inc. to conduct a Phase 2 proof-of-concept study of an all-oral regimen for the treatment of hepatitis C containing Vertex’s nucleotide analogue hepatitis C virus (HCV) polymerase inhibitor VX-135 and Janssen’s protease inhibitor simeprevir (TMC435). As part of the collaboration, Janssen will conduct a drug-drug interaction study with VX-135 and simeprevir to support the planned initiation of a Phase 2 proof-of-concept study in early 2013, pending discussions with regulatory authorities. The Phase 2 study is expected to evaluate safety, tolerability and viral cure rates using a 12-week combination of VX-135 and simeprevir. The companies will jointly fund development costs associated with the collaboration. There are no up-front or milestone payments associated with the agreement. VX-135 is an investigational uridine nucleotide analogue pro-drug designed to inhibit the replication of the hepatitis C virus by acting on the NS5B polymerase. Simeprevir is a potent, once-daily investigational hepatitis C protease inhibitor, currently in Phase 3 trials, being jointly developed by Janssen R&D Ireland and Medivir AB. “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 Robert Kauffman, M.D., Ph.D., Senior Vice President and Chief Medical Officer at Vertex. “We believe that an all-oral regimen of VX-135 and simeprevir has the potential to achieve high cure rates with only 12 total weeks of treatment for people with hepatitis C, and we look forward to the start of the Phase 2 proof-of-concept study with Janssen." 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. About VX-135 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 the United States. 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). Vertex gained worldwide rights to VX-135 through an exclusive licensing agreement signed with Alios BioPharma, Inc. in June 2011. The agreement also includes a research program that will focus on the discovery of additional nucleotide analogues that act on hepatitis C polymerase. Vertex has the option to select additional compounds for development emerging from the research program. About Simeprevir (TMC435) Simeprevir is a once-daily potent investigational hepatitis C protease inhibitor in late Phase 3 clinical development being jointly developed by Janssen R&D Ireland and Medivir AB to treat chronic hepatitis C virus infections. Simeprevir is being investigated in combination with PegIFN/RBV in Phase 3 trials and is also being evaluated with Direct-acting Antiviral (DAA) agents in three other Phase 2 interferon-free combinations both with and without ribavirin (RBV).

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 the United States, up to 5 million people have chronic hepatitis C and 75 percent of them are unaware of their infection.^9,10 Hepatitis C is four times more prevalent in the United States compared to HIV.^10 The majority of people with hepatitis C in the United States were born between 1945 and 1965, accounting for 82 percent of people with the disease.^11 Hepatitis C is the leading cause of liver transplantations in the United States and is reported to contribute to 15,000 deaths annually.^12,13 By 2029, total annual medical costs in the United States for people with hepatitis C are expected to more than double, from $30 billion in 2009 to approximately $85 billion.^10 About Vertex Vertex creates new possibilities in medicine.
