Return to the newsletter >> Aventis and U.S. Department of Health and Human Services Enter into Third Pandemic Influenza Vaccine Agreement
− World's Largest Influenza Vaccine Producer Plays Leading Global Role In Influenza Pandemic Planning −
Aventis, part of the sanofi-aventis Group, has been awarded a contract by the U.S. Department of Health and Human Services (HHS) to establish and maintain flocks of egg-laying hens and to maintain other essential supplies to ensure its ability to manufacture pandemic influenza vaccine at current full capacity on a year-round basis. Currently, egg capacity exists only on a seasonal basis to support normal influenza vaccine production. Pandemic influenza planning is considered a major global public health priority.
Under the terms of the agreement, the company will receive $10 million for the first year of the contract. The government has the option to extend the agreement for up to four additional years, giving the contract a potential total value of $41 million over a five-year period. The agreement also calls for Aventis Pasteur, the human vaccines business of Aventis, part of sanofi-aventis Group, to manufacture, on an annual basis, investigational influenza vaccine of a candidate pandemic-like strain. HHS will identify the strain to be used in the investigational lot each year and will provide the reference virus on which each investigational lot will be based.
"As a global vaccine leader, Aventis Pasteur is committed to supporting international public health efforts to prepare for an influenza pandemic," said David J. Williams, chairman and chief executive officer of Aventis Pasteur. "The company is already involved in multiple pandemic vaccine development efforts in Europe and the United States. We welcome opportunities to discuss similar flock preservation initiatives with government health authorities around the world."
Aventis and Global Influenza Pandemic Planning Aventis Pasteur is the only vaccine manufacturer selected to participate in FLUPAN, a collaboration funded by the European Union (E.U.) with the U.K.'s National Institute for Biological Standards and Control (NIBSC) and the University of Reading. FLUPAN is intended to improve the level of pandemic preparation in the E.U. The company will produce pandemic influenza vaccine that will be used in a FLUPAN clinical study.

FLUPAN is intended to improve the level of pandemic preparation in the E.U. The company will produce pandemic influenza vaccine that will be used in a FLUPAN clinical study.
Aventis Pasteur is also one of several manufacturers asked by the World Health Organization (WHO) in February 2004 to produce avian influenza vaccine candidates for use in clinical studies to determine safety, immunogenicity and proper dosage. In 2005, Aventis Pasteur will complete production of clinical lots of an H5N1 egg-based influenza vaccine using a strain provided by NIBSC. The clinical lots are being developed as part of an E.U. program in collaboration with the French health authorities, NIBSC and EMEA (European Medicines Agency). The data from these studies will be used in a mock dossier submitted to the EMEA to accelerate the license approval process in the event of a pandemic.
The H5N1 strain is an avian virus strain that emerged in Southeast Asia and other countries late last year and continues to circulate. It has the potential to become a human pandemic strain. The HHS contract represents the third agreement that Aventis Pasteur has entered into with the U.S. Government. Earlier this year, Aventis Pasteur contracted with the National Institute of Allergy and Infectious Diseases (NIAID), part of the U.S. National Institutes of Health, to produce 8,000 doses of the H5N1 influenza strain. Subsequently, the company signed a contract with HHS to produce 2 million doses of bulk vaccine derived the same virus strain. Seed virus for the H5N1 vaccine being produced under the U.S. contracts was provided by NIAID. The seed virus is a reassortant containing two genes from the wild type virus that expresses the immunogenic antigens and was extensively tested prior to delivery to Aventis Pasteur.
Influenza epidemics occur every year and result in an average of 36,000 deaths and 200,000 hospitalizations in the United States, mostly among chronically ill persons and seniors, according to the Centers for Disease Control and Prevention (CDC). An influenza pandemic is a global epidemic of an especially virulent virus with the potential for severe morbidity and mortality. According to the WHO, the next pandemic is likely to result in 1 to 2.3 million hospitalizations and 280,000 to 650,000 deaths in industrialized nations. Its impact will most likely be even more devastating in developing countries.

Return to the newsletter >> Study Identifies Molecular Complex Vital to Creation of miRNAs: Possible Links to DiGeorge Syndrome, Schizophrenia Also Seen
Tiny bits of short-lived genetic material called microRNAs, or miRNAs, have attracted enormous interest from scientists since their discovery in humans only a few years ago. Viewed most broadly, they appear to play significant roles in controlling gene expression and development in many different settings.
Now, a new study from researchers at The Wistar Institute identifies for the first time a molecular complex vital for the creation of miRNAs. This complex, dubbed the microprocessor complex, contains two proteins, one of which has been linked to DiGeorge syndrome, the most common disorder of genetic deletion in humans. A swathe of DNA containing multiple genes is missing in DiGeorge syndrome patients, and many are born with heart defects, immune deficiencies, and developmental and behavioral problems. Intriguingly, one in four also goes on to develop schizophrenia, a disorder for which causative genes have yet to be identified. The new study appeared in the November 11 issue of Nature.
“Discovery of this microprocessor complex gives us important insights into the processing mechanisms that generate miRNAs in the body,” says Ramin Shiekhattar, Ph.D., an associate professor at Wistar and senior author on the Nature study. “At the same time, we see that one of the components of the complex is implicated in DiGeorge syndrome, suggesting that miRNA activity - or its lack - may be pivotal in the disease process of that multifaceted disorder.”
The genes that code for miRNAs initially gives rise to a long primary RNA molecule that must first be cut into small precursor RNA molecules before final processing into mature miRNAs. The finished miRNAs are remarkably small, only 22 nucleotides in length, but powerful. These molecules appear to work by binding to complementary regions in messenger RNA, responsible for translating genes into proteins, or even to certain stretches of DNA. Either way, the result is gene silencing, which is one of the body’s main strategies for regulating genes.
The microprocessor complex discovered by Shiekhattar’s team is composed of two proteins called Drosha and DGCR8. Drosha had been previously identified as being involved in miRNA processing, but the role of DGCR8 is newly seen here. The Wistar scientists showed that both DGCR8 and Drosha were necessary for the processing of primary miRNA into a precursor miRNA - neither alone was sufficient to do the job. In another set of experiments, DGCR8 was intentionally inactivated, which led to excessive accumulations of the primary microRNA.
DGCR8 is one of the several genes deleted in DiGeorge syndrome, and this link suggests several paths for future investigations. Shiekhattar plans, for example, to develop a strain of mice lacking the gene for DGCR8 to see whether they display any of the characteristics of DiGeorge syndrome. He also aims to study DiGeorge syndrome patients to see whether they exhibit the excessive accumulations of primary RNA that might be expected due to a DGCR8-deficient, and therefore nonfunctional, microprocessor complex.
Scientists have noted, too, that miRNAs are critical for proper neuronal development. Might miRNA activity, then, provide a new window on schizophrenia, at least in DiGeorge syndrome patients, but perhaps also more globally?
“It would certainly be possible to look in schizophrenic populations for mutations in the DGCR8 gene,” says Shiekhattar. “If those mutations were found, it could suggest of a significant role for miRNAs in schizophrenia.”
In the course of their study of the microprocessor complex, the Wistar scientists also identified a second and much larger molecular complex that also incorporates Drosha. This complex contains about 20 proteins, and another goal for Shiekhattar’s team in the future will be to ascertain the as-yet-unknown biological role of this complex.

Return to the newsletter >> Yaupon Therapeutics Initiates Clinical Trials for First Agent to Treat Epidemic of Methamphetamine Addiction
- Also Planning Phase II/III Trials for Agent to Treat Cutaneous T-Cell Lymphoma -
Yaupon Therapeutics, a specialty pharmaceutical company developing products for central nervous system disorders and cancer, announced it has initiated a phase I trial for lobeline for the treatment of methamphetamine addiction. The company also revealed that early next year it intends to begin phase ll/lll clinical trials of a new topical agent, Clearazide(TM), for the treatment of cutaneous T-cell lymphoma.
Lobeline is derived from a natural product with a long history of safety in human use. In animal studies, it has been shown to be effective in treating methamphetamine addiction. In recent years, the wide availability and highly addictive nature of methamphetamine have led to a tripling in the number of abusers, with over a million Americans now addicted, and have resulted in tremendous social, economic and personal costs. Until now, there has been no effective treatment for methamphetamine addiction. Yaupon is conducting phase l studies of lobeline with the University of California at San Francisco, with funding from the National Institute of Drug Abuse.
"Embarking on clinical trials for two medically significant indications just two years after establishing our company represents a major achievement for Yaupon," said Mr. Alonso. "Methamphetamine is notoriously addictive, and it has devastated large numbers of American families and their communities. We are proud to be developing what may be the first agent to treat this damaging addiction."
Yaupon's progress in advancing lobeline into human studies was supported by an investment earlier this year from BioAdvance, the Biotechnology Greenhouse of Southeastern Pennsylvania. The Greenhouse Fund investment was specifically targeted at enabling Yaupon to hire critical clinical and regulatory personnel needed for the clinical program.
"Yaupon's success at launching clinical trials for lobeline and Clearazide illustrates the importance of our mission to provide critical support to promising life sciences enterprises in our region," said Barbara Schilberg, CEO and managing director of BioAdvance. "Lobeline may offer real promise for the millions affected by methamphetamine addiction, and we are pleased that BioAdvance was able to contribute to making these clinical trials possible."
Clearazide, Yaupon's lead product candidate for cancer, is slated to enter pivotal clinical trials next year. Clearazide is a topical cytotoxic agent that has shown promise in early clinical trials in the treatment of cutaneous T-cell lymphoma, a difficult-to-treat skin cancer that afflicts 20,000 Americans. Clearazide has been designated an orphan drug by the Food and Drug Administration (FDA) for this condition. If successful, Yaupon expects to begin marketing this compound in 2007.
"Cutaneous T-cell lymphoma is a disfiguring cancer that is often fatal if not treated early," added Mr. Alonso. "We, look forward to initiating these clinical trials which are intended to confirm earlier findings supporting the clinical utility of Clearazide in helping to manage this difficult condition."
