CAMBRIDGE, Mass., Jul 28, 2010 (BUSINESS WIRE) -- Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today provided an update on recent progress in its development programs in hepatitis C virus (HCV) infection, cystic fibrosis (CF) and other diseases and reported consolidated financial results for the quarter ended June 30, 2010.
"We remain on track to complete the New Drug Application submission process for telaprevir later this year and to complete the buildout of our commercial function in advance of the potential launch of telaprevir," said Matthew Emmens, Chairman, President and Chief Executive Officer of Vertex Pharmaceuticals. "In the first half of this year, we established a seasoned commercial leadership team with broad experience in the area of infectious diseases, and we continue to bolster the internal infrastructure needed to support a field-based sales force for telaprevir and other potential future medicines.
"Our Phase 3 registration program in cystic fibrosis is now fully enrolled, positioning us for the planned submission of a New Drug Application for VX-770 in the second half of 2011. There is an urgent need for new and more effective therapies in cystic fibrosis, and we are committed to working toward improving the lives of people affected by this disease.
"As our development programs and commercial efforts advance, we remain focused on the management of our capital structure. We ended the second quarter of 2010 with a cash position of approximately $980 million, positioning us for continued investment in key activities to help support a successful potential launch for telaprevir," concluded Mr. Emmens.
Recent Clinical Development Progress
Telaprevir Phase 3 Program in Hepatitis C

* Vertex expects efficacy and safety data from the supplemental Phase 3 ILLUMINATE trial to become available in August 2010, followed by efficacy and safety data from the pivotal Phase 3 REALIZE trial in September 2010.
* The ILLUMINATE trial of telaprevir-based regimens is designed to evaluate the comparability of the sustained viral response (SVR), or viral cure, rates between the 24-week and 48-week treatment arms in treatment-naïve people with genotype 1 hepatitis C who achieved undetectable virus levels at weeks 4 and 12 of treatment (eRVR) and who remained in the trial through week 20. Patients who met these criteria were randomized at week 20 to receive either 24 or 48 total weeks of therapy.
* The REALIZE trial is being conducted by Vertex's collaborator Tibotec and is evaluating telaprevir in people with genotype 1 hepatitis C who did not achieve SVR, or a viral cure, with a prior pegylated interferon-based treatment, including difficult-to-treat null responder patients and patients who had a partial response or relapse in prior therapy. This is the only current Phase 3 trial of an investigational therapy for hepatitis C to enroll a difficult-to-treat patient population that includes patients who had a null response to a prior course of pegylated-interferon and ribavirin therapy.
·Data from ILLUMINATE are expected to supplement the data obtained in the two pivotal Phase 3 trials of telaprevir - ADVANCE and REALIZE - as part of the planned New Drug Application (NDA) submission for telaprevir.
Rolling NDA Submission Underway
·Vertex recently submitted the Non-clinical and the Chemistry, Manufacturing and Controls (CMC) sections of its NDA to the U.S. FDA as part of a rolling NDA submission for telaprevir. The company remains on track to complete the NDA submission for telaprevir in the second half of 2010.
Phase 3b Trial to Evaluate Twice-Daily (BID) Compared to Three-Times-Daily Dosing of Telaprevir
·In the fourth quarter of 2010, Vertex and its collaborator Tibotec expect to initiate 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). This trial is expected to enroll approximately 700 treatment-naïve people with genotype 1 hepatitis C in two telaprevir-based treatment arms and will be conducted in the U.S., E.U. and certain other countries. Based on advice from regulatory authorities in the U.S. and E.U., the trial will not include a control arm of pegylated-interferon and ribavirin.
Telaprevir/VX-222 Combination Trial
·Vertex is currently conducting the first clinical trial to evaluate telaprevir dosed in combination with Vertex's lead HCV polymerase inhibitor, VX-222. This Phase 2 proof-of-concept trial is designed to evaluate SVR, or viral cure, rates using multiple 12-week response-guided regimens of telaprevir/VX-222-based combination therapy, including two-drug regimens that contain only telaprevir and VX-222. Vertex expects to obtain on-treatment clinical data from this trial in the second half of 2010.
