|Incyte and Pharmasset Enter into a Collaborative Licensing Agreement for a Phase II HIV Drug|
WILMINGTON, Del. & ATLANTA, Sep 8, 2003 -- Incyte Corporation (Nasdaq: INCY) and Pharmasset, Ltd. announced today that they have entered into a collaborative licensing agreement to develop and commercialize the antiretroviral drug Reverset(TM), also known as RVT, D-D4FC or DPC-817, which is currently in Phase IIa clinical development for the treatment of human immunodeficiency virus (HIV) infections under an approved US FDA Investigational New Drug (IND) application. Incyte will pay Pharmasset an upfront payment as well as performance milestone payments and future royalties on net sales in exchange for exclusive rights in the U.S., Europe and certain other markets to develop, manufacture and market the drug. Pharmasset will retain marketing and commercialization rights in certain territories, including South America, Mexico, Africa, the Middle East, Korea and China.
Reverset is an oral, once-a-day nucleoside analog that targets the HIV-1 and HIV-2 reverse transcriptase. Preclinical studies indicate that Reverset inhibits replication of wild type and mutant strains of HIV commonly seen after treatment with zidovudine (ZDV) and lamivudine (3TC), including strains that exhibit the M184V mutation. These studies also suggest that Reverset does not produce mitochondrial toxicity, a common side effect associated with certain nucleoside reverse transcriptase inhibitor (NRTI) therapies that can lead to fairly serious and life-threatening bone marrow suppression.
In a Phase I ascending-single dose, pharmacokinetic and safety study in 56 HIV-1 infected male volunteers, the drug was well tolerated with mild adverse events occurring no more frequently with drug than with placebo.
Pharmasset is currently conducting a 10-day dose-escalating Phase II clinical trial of Reverset for HIV infection. This trial involves treatment naive HIV patients. A second Phase II trial using Reverset, in combination with other antiretroviral agents in drug-experienced individuals, is expected to begin in early 2004.
Paul Friedman, M.D., Incyte's chief executive officer, stated, "The scientific community has made great strides in developing effective new HIV therapies; however, there remains a critical need for new therapies that address the drug resistance which often occurs after exposure to first-generation HIV drugs. Additionally, there is a growing incidence of transmission of resistant HIV in treatment naive patients. Data from preclinical and clinical studies of Reverset suggest it may be a useful and convenient HIV treatment, particularly among patients who are resistant to standard HIV therapies. We look forward to continuing the clinical development of Reverset with Pharmasset, confirming its therapeutic value and to seeking marketing clearance once pivotal studies are completed."
Abel De La Rosa, Ph.D., Pharmasset's Senior Vice President of Business and Scientific Development, stated, "We are pleased to enter into this collaborative agreement with Incyte. Through the combined expertise and resources of our scientific and clinical management teams, Pharmasset and Incyte will work to accelerate the development of Reverset to rapidly transform this potent drug into a viable once-a-day treatment option for patients infected with HIV."
Pharmasset (www.pharmasset.com) is an antiviral and anticancer drug discovery, development, and commercialization company. Pharmasset is committed to the development of novel, patentable, proprietary chemical agents, primarily nucleosides, as treatments for life-threatening diseases, such as HIV, hepatitis viruses and cancers.
