LA JOLLA, Calif.--(BUSINESS WIRE)--Nov. 3, 1997--Sequana Therapeutics, Inc. (NASDAQ:SQNA) Monday announced a broad-based genomics alliance with the Parke-Davis division of Warner-Lambert Company (NYSE:WLA) to develop novel therapeutic products for schizophrenia and bipolar disorder (manic depression), two of the most debilitating central nervous system (CNS) disorders.  The alliance will combine Sequana's capabilities in gene discovery, functional genomics, bioinformatics and high-throughput screening with Parke-Davis' research, development and clinical expertise in the CNS area.     The agreement provides for payments to Sequana of up to $103 million in the form of up-front licensing fees, research funding and milestone payments, almost half of which represents committed funding.  In addition, Sequana will receive royalties on sales of any small molecule therapeutic products resulting from the alliance.  The term of the alliance is five years, extendible in one-year increments to a period of eight years with commensurate increases in research funding.  Parke-Davis gains exclusive worldwide commercial rights for small molecule therapeutic products, while Sequana retains worldwide rights to develop and commercialize recombinant protein, antisense, gene therapy, vaccine, diagnostic, prognostic and pharmacogenetic products and services.     The size and scope of this alliance reflects Sequana's expanded "gene to lead" approach and its ongoing strategy to play an increasingly important role in the drug discovery process.  Sequana's approach integrates the company's proven gene discovery technologies with its advanced functional genomics and high- throughput screening capabilities.  Sequana has built or refined several functional genomics and screening technologies over the past two years, including the company's RAMMP(TM) (RApid Mouse Model Production) technology for transgenic animal studies, DNA chip-based expression systems, computational biology tools, and the proprietary NemaScreen(R) technology for high-throughput screening using the well-characterized nematode worm.     As part of the alliance, Sequana also will grant Parke-Davis a non-exclusive license to use certain of the company's bioinformatics software tools for the collection and analysis of genomic data, including LIMS-Lite(TM), SequaSearch(TM) and BioAgent DB(TM), among other proprietary tools.  Sequana believes that the application of these bioinformatics technologies at Parke-Davis' laboratory facilities will increase the speed and efficiency at which the companies can develop commercial products while aiding Parke-Davis in its expansion of its internal genomics capabilities.     "This partnership with Parke-Davis gives us the opportunity to fuse our broad range of genomics technologies into one comprehensive program aimed at finding promising lead compounds to treat common psychiatric disorders," commented Kevin J. Kinsella, president and CEO of Sequana.  "We look forward with great enthusiasm to combining Sequana's gene-based discovery capabilities with Parke-Davis' strong research and development expertise in the CNS area."     "Sequana brings to this collaboration what we think is the best mix of genomics technologies in the industry," added Leonard Post, Ph.D, Vice President of Discovery Research at Parke-Davis.  "This collaboration promises to be both an important step for Parke-Davis in the field of genomics, and a major component of our future discovery strategies in psychiatric diseases."     Schizophrenia and bipolar disorder, two of the most chronic, debilitating and costly mental illnesses, afflict approximately five million Americans and cost the United States more than $50 billion annually, according to the National Institute of Mental Health.  The overt symptoms of schizophrenia include hallucinations, delusions, and bizarre thought patterns, while characteristics of bipolar disorder involve fluctuations between mania and depression.     To date, Sequana has collected DNA samples from several hundred families affected by schizophrenia and bipolar disorder, has completed full genome scans, and has identified several small genetic regions which the company believes contain one or more genes associated with each disease.  With the signing of this agreement, Sequana will continue efforts to narrow these genetic regions in search of disease-causing genes and, together with Parke-Davis, will analyze candidate genes and drug targets using Sequana's large-scale gene expression technologies and developmental biology expertise. Upon the identification of molecular targets, Sequana plans to utilize its NemaScreen(R) technology to screen for potential small molecule compounds using Parke-Davis' compound library.     Sequana Therapeutics, Inc. (NASDAQ: SQNA) is a leading genomics company that uses industrial-scale gene discovery and functional genomics technologies to develop products aimed at diagnosing and treating common human diseases.  Sequana has ongoing discovery programs in asthma, diabetes, obesity, osteoporosis, schizophrenia and manic depression, among other important disease areas, and has scientific collaborations with several major pharmaceutical and biotechnology companies worldwide.  Sequana employs approximately 200 people at its headquarters in La Jolla, California and at its subsidiary, NemaPharm, Inc., in Cambridge, Massachusetts. Information about Sequana may be obtained on the World Wide Web at sequana.com or by phoning (619) 452-6550.     Parke-Davis is devoted to discovering, developing, manufacturing and marketing quality pharmaceutical products.  Parke-Davis Pharmaceutical Research, headquartered in Ann Arbor, Michigan, is a division of Warner-Lambert Company (NYSE: WLA), whose three principal lines of business include pharmaceutical, consumer healthcare and confectionery products.  Warner-Lambert employs approximately 40,000 people and is headquartered in Morris Plains, New Jersey.     The statements in this news release relating to the potential discovery of disease genes, the subsequent development of products for schizophrenia and bipolar disorder, and the payments to be paid to Sequana by Parke-Davis are forward looking statements, which involve risks and uncertainties, including Sequana's ability to utilize its technologies to discover genes and to translate gene discoveries into potential drug leads, the successful continuation of the collaboration between Sequana and Parke-Davis, Sequana's ability to find more than one gene for each disease area, the ability of Sequana and Parke-Davis to identify multiple targets for therapeutic intervention, the ability of Parke-Davis to develop and commercialize small molecule therapeutic products based on Sequana's gene discoveries, and the impact of competitive gene discoveries, technologies and potential products.  For a discussion of the other risks and uncertainties potentially affecting Sequana's business, see the company's Form 10-K for the year ending December 31, 1996. Actual results and the timing of certain events could differ materially from those indicated in the forward looking statements as a result of these or other factors.
