Vertex Licenses VX-787 to Janssen Pharmaceuticals for the Treatment of Influenza

Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced that it has entered into a licensing agreement with Janssen Pharmaceuticals, Inc. for the worldwide development and commercialization of VX-787, a novel medicine discovered by Vertex for the treatment of influenza. As part of the agreement, Vertex will receive an up-front payment of $30 million from Janssen and has the potential to receive additional development and commercial milestone payments as well as royalties on future product sales. Vertex completed a Phase 2a study of VX-787 in 2013 that showed statistically significant improvements in viral and clinical measurements of influenza infection. VX-787 is designed to directly inhibit replication of the influenza virus.

“With a deep history in developing new medicines for viral infections and diseases, Janssen is well-positioned to advance the global development of VX-787 for the treatment of influenza,” said Jeffrey Leiden, M.D., Ph.D., Chairman, President and Chief Executive Officer of Vertex. “This collaboration provides important support for the continued development of VX-787 in influenza and contributes to our financial strength to enable continued investment in our key development programs for cystic fibrosis and in research aimed at discovering new medicines.”

About the Collaboration

Under the terms of the collaboration, Janssen will have full global development and commercialization rights to VX-787. Vertex will receive a $30 million up-front payment from Janssen and could receive additional development and commercial milestone payments as well as royalties on future product sales. The collaboration, and the related $30 million up-front payment, is subject to the expiration of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act.

About VX-787

VX-787 is an investigational medicine that is designed to directly inhibit replication of influenza A, including recent H1 (pandemic) and H5 (avian) influenza strains, based on in-vitro data. VX-787’s mechanism represents a new class of potential medicines for the treatment of influenza, distinct from neuraminidase inhibitors, the current standard of care for the treatment of influenza. VX-787 is intended to provide a rapid onset of action and an expanded treatment window.

In a Phase 2a influenza challenge study, statistically significant improvements in viral and clinical measurements of influenza infection were observed after treatment with VX-787. The study met its primary endpoint and showed a statistically significant decrease in the amount of virus in nasal secretions (viral shedding) over the seven-day study period. In addition, at the highest dosing regimen evaluated in the study, there was a statistically significant reduction in the severity and duration of influenza-like symptoms. In this study, VX-787 was generally well-tolerated, with no adverse events leading to discontinuation. Those who took part in the study volunteered to be experimentally exposed to an attenuated form of live H3N2 influenza A virus. H3N2 is a common type of influenza virus and was the most common type observed in the 2012/2013 influenza season in the United States.

VX-787 was discovered by Vertex scientists.

About Influenza

Often called “the flu,” seasonal influenza is caused by influenza viruses, which infect the respiratory tract.1 The flu can result in seasonal epidemics2 and can produce severe disease and high mortality in certain populations, such as the elderly.3 Each year, on average 5 to 20 percent of the U.S. population gets the flu4 resulting in more than 200,000 flu-related hospitalizations and 36,000 deaths.5 The overall national economic burden of influenza-attributable illness for adults is $83.3 billion.5 Direct medical costs for influenza in adults totaled $8.7 billion including $4.5 billion for adult hospitalizations resulting from influenza-attributable illness.5 The treatment of the flu consists of antiviral medications that have been shown in clinical studies to shorten the disease and reduce the severity of symptoms if taken within two days of infection.6 There is a significant need for new medicines targeting flu that provide a wider treatment window, greater efficacy and faster onset of action.

About Vertex

Vertex is a global biotechnology company that aims to discover, develop and commercialize innovative medicines so people with serious diseases can lead better lives. In addition to our clinical development programs focused on cystic fibrosis, Vertex has more than a dozen ongoing research programs aimed at other serious and life-threatening diseases.

Vertex Pharmaceuticals’ Boston Campus, United States of America

Lynette Hopkinson VP Commercial Regulatory Affairs, Global Regulatory Affairs Vertex Pharmaceuticals Incorporated, United States

swati Patel, a lead analyst, shared a toast with Mir Hussain, a systems engineer, at Vertex Pharmaceuticals during the Friday beer hour, which features beer and chips for employees.

On Fridays around 5 o’clock, after a hard week of work, Frank Holland likes to unwind with a beer. And he doesn’t have to leave work to get one.

Holland is a research scientist at Vertex Pharmaceuticals, which every Friday rings in “beer hour,” offering free adult beverages and munchies to its 1,300 Boston employees.

For Holland, the weekly ritual is a chance to escape the bubble of his chemistry lab and bump into colleagues from other departments — as well as Vertex’s top executives, who regularly attend. For those who prefer grapes to hops, there is also wine.

“Some of the other companies I worked at, you really had to go out of your way to meet people,” said Holland, 32. “At Vertex all you have to do is show up in the cafeteria on a Friday afternoon.”

Sure, free beer is common at hip tech offices; some even have their own bars. But Vertex, best known for its treatment for cystic fibrosis, was doing this way before it was cool. The beer-hour tradition goes back to the company’s founding days, in 1989. Back then, it was just two dozen people in a small office in Cambridge. Someone went to a corner store, bought a case of beer and some chips, and beer hour was born.
