Vertex Pharmaceuticals Reports Third Quarter 2010 Financial Results and Highlights Progress in Hepatitis C and Cystic Fibrosis Development Programs

-Hepatitis C: New Drug Application submission for telaprevir on track for fourth quarter 2010-

CAMBRIDGE, Mass., Oct 25, 2010 (BUSINESS WIRE) -- ---Cystic Fibrosis: Phase 3 registration program ongoing for VX-770-

---Pipeline: Ongoing proof-of-concept clinical trials in hepatitis C, cystic fibrosis, epilepsy and rheumatoid arthritis-

---Financial: Company ends third quarter with a cash position of $1.2 billion- Vertex Pharmaceuticals Incorporated today reviewed recent business and clinical progress and reported consolidated financial results for the quarter ended September 30, 2010.

"With the recent completion of our Phase 3 registration program for telaprevir, we remain on track to submit our New Drug Application in the coming weeks, marking what we believe will be an important milestone in our effort to bring telaprevir to people with hepatitis C," said Matthew Emmens, Chairman, President and Chief Executive Officer of Vertex Pharmaceuticals.

Mr. Emmens continued, "Later this week, clinical investigators will present Phase 3 data for telaprevir at the annual AASLD meeting in Boston. We continue to have high confidence in the potential for telaprevir to help the majority of people with hepatitis C -- regardless of their treatment history -- and we look forward to sharing additional telaprevir data with the medical community. "Importantly, with a cash position of $1.2 billion at the end of the third quarter, we will enter 2011 with the financial strength needed to support the planned launch of telaprevir as well as the continued discovery and development of other new breakthrough medicines," concluded Mr. Emmens.

Telaprevir Phase 3 Program Complete; Rolling NDA Submission On Track In the third quarter, Vertex completed its Phase 3 registration program for telaprevir. The company remains on track to complete the submission of its rolling New Drug Application (NDA) for telaprevir in combination with pegylated-interferon and ribavirin in the fourth quarter of 2010 with clinical data from its three Phase 3 trials in people who had not been previously treated for hepatitis C and in people who received prior treatment but were not cured. Phase 3 ADVANCE and ILLUMINATE Trials to be Presented at AASLD This Week Vertex expects that final sustained viral response (SVR or viral cure) and safety data from the Phase 3 ADVANCE and ILLUMINATE trials will be presented as part of oral presentation sessions at the upcoming annual meeting for the American Association for the Study of Liver Diseases (AASLD or The Liver Meeting), being held October 29 to November 2 in Boston. In total, eight Vertex abstracts were accepted for presentation at the AASLD meeting.

Initiation of Phase 3b Clinical Trial to Evaluate Twice-Daily (BID) Dosing of Telaprevir

Vertex today announced the initiation of a Phase 3b clinical trial to evaluate twice-daily dosing of telaprevir (1,125 mg; BID) compared to three-times-daily dosing of telaprevir (750 mg; q8h) in combination with pegylated-interferon and ribavirin for people with genotype 1 hepatitis C. Patient screening for enrollment in the study is expected to start in November 2010. Additional details on this trial were provided today in a separate press release. Ongoing Phase 2 Trial Evaluating Combination Regimens of VX-222 and Telaprevir Vertex announced today that it has modified its clinical trial evaluating telaprevir dosed in combination with Vertex's lead HCV polymerase inhibitor, VX-222. The company will discontinue Arm A of this study as a result of patients meeting a pre-defined stopping rule related to viral breakthrough during the first four weeks of dosing. Arm A was designed to evaluate a two-drug regimen of VX-222 (low dose; 100 mg) and telaprevir (1,125 mg) both dosed twice daily without pegylated-interferon and ribavirin. The additional three arms of the study are continuing without modification, and no viral breakthrough has been reported in these arms. This Phase 2 proof-of-concept trial began dosing patients in August 2010 and is designed to evaluate safety and SVR rates using 12-week response-guided regimens of telaprevir/VX-222-based combination therapy in people with genotype 1 hepatitis C. The trial is continuing to evaluate treatment regimens that include four-drug regimens of telaprevir, VX-222, pegylated-interferon and ribavirin, as well as a two-drug regimen of only telaprevir (1,125 mg) and a higher dose of VX-222 (400 mg), both dosed twice daily. Trial sites have now completed patient recruitment, which Vertex expects will enable it to reach the initial target enrollment of 100 patients for the study. Vertex expects to obtain on-treatment clinical data from this trial in the first half of 2011 and SVR data in the second half of 2011.

Enrollment Complete in Phase 2 Trial Evaluating Telaprevir in People Co-Infected with Hepatitis C Virus and Human Immunodeficiency Virus

Vertex today announced that it has completed enrollment of 60 patients in a Phase 2 clinical trial of telaprevir-based regimens in people who are infected with genotype 1 hepatitis C virus and the human immunodeficiency virus (HIV), also know as HCV-HIV co-infection. The primary endpoint of the trial is to evaluate the safety and tolerability of telaprevir-based therapy in people co-infected with HCV and HIV. A secondary endpoint is to evaluate SVR, or viral cure, rates. The trial enrolled 13 people who had not previously received treatment for hepatitis C and who were not currently being treated for HIV infection. The trial also enrolled 47 people who had not previously received treatment for hepatitis C and who were currently being treated for HIV infection with highly active antiretroviral therapy (HAART). Of the 47 patients on HAART, 23 were receiving a Reyataz-based regimen and 24 were receiving Atripla.
