GAITHERSBURG, MD, January 20, 2011 – MedImmune’s Oncology group announced today preclinical results showing that MEDI-573, a targeted monoclonal antibody, broadly suppresses pathways that have been shown to play a critical role in the development and progression of many solid tumors. The study, published in the February 1 issue of Cancer Research (a journal of the American Association for Cancer Research), suggests that MEDI-573 inhibits multiple biological pathways related to cancer. 

 MEDI-573 is the only human monoclonal antibody (MAb) currently under clinical development that neutralizes both insulin-like growth factor (IGF)-I and IGF-II, growth hormones that regulate cell growth, survival, differentiation, and transformation (i.e., the process of acquiring cancerous characteristics). This MedImmune compound specifically inhibits IGF signaling through two important pathways: IGF-1R and IR-A (insulin receptor isoform A). Unlike the other IGF-1R-targeting MAbs in development that target only IGF-1R, MEDI-573 neutralizes both the receptors IGF-1R and IR-A as well as their hybrid receptors.  In addition, MEDI-573 spares the insulin receptor isoform B (IR-B), which interacts with insulin and is crucial for the metabolism of glucose – the body’s main source of energy. Therapies that affect IR-B have been shown to raise or drop blood sugar levels, both of which can cause serious health problems. Preliminary data from MedImmune’s first-time-in-human study suggest that MEDI-573 does not alter glucose homeostasis.

“MEDI-573 represents an innovative approach for the treatment of solid tumors with the potential for greater and more consistent inhibition of cancer cell growth than treatments that only target one pathway,” said Jin Gao, Ph.D., Scientist II in Oncology Research at MedImmune and lead author of the study.  “The data from our pre-clinical studies are highly promising.  Ongoing studies in humans will provide us with a better understanding of the clinical impact of MEDI-573.”

This in vivo study demonstrates that MEDI-573 inhibited the activity of IGF signaling pathways in mice implanted with two different tumor cell lines, C32 and P12.  In this study, 86% and 91% tumor growth inhibition (TGI) was achieved in mice treated with 30 or 60 mg/kg MEDI-573, respectively.

 In addition, the study found that using ¹⁸F-FDG-PET imaging (fluorodeoxyglucose positron emission tomography) may provide a non-invasive way to monitor treatment response within a few days of starting treatment, prior to documented reductions in the tumor size.

About MEDI-573 (Anti-IGF MAb)

IGF signaling pathways play an important role in the development and progression of many solid tumors.  Disruption of IGF signaling pathways by neutralizing IGF-I and IGF-II ligands enables broader suppression of the IGF system and is a novel strategy for the treatment of solid tumors.  MEDI-573 is a dual-targeting fully human monoclonal antibody that neutralizes IGF-I and IGF-II ligands. In preclinical studies, this neutralization was shown to block IGF-1R, IGF-1R/ IR-A hybrid and IR-A signaling, which inhibited cancer cell growth.  MEDI-573 is in phase 1 clinical evaluation in patients with advanced solid tumors and is planned to begin phase 2 studies this year.

“Cancer research has long been a priority focus area at MedImmune and we are proud of the organization’s hard work to achieve first-time-in-human-status for all three candidates,” said Laurence Moore, M.D., Ph.D., vice president, clinical development, oncology. “We look forward to continuing to evaluate how managing the various biological targets inherent in these very different antibodies may potentially lead to better health outcomes for patients suffering from a myriad of cancers.”

• MEDI-573: is a fully human antibody that selectively binds to
  insulin-like growth factors (IGFs) I and II and inhibits IGF I and II
  mediated signal transduction in tumor cells; thus this antibody could
  potentially inhibit tumor growth.
• MEDI-575: is a fully human antibody targeting the platelet-derived
  growth factor-receptor (PDGF receptor) subunit, which is thought to play an
  important role in human cancers, both as a direct target on tumor
  cells and as a mediator of stromal support for cancer cell growth.
  The interaction between stromal cells and tumor cells is known to play
  a major role in cancer growth and progression; therefore, blocking
  PDGF alpha with an effective antibody could potentially reduce the
  growth and metastases of solid tumors.
• MEDI-547, an antibody-drug conjugate, is a fully human monoclonal
  antibody designed to target the over expression of the EphA2 protein
  linked to a potent drug payload. Cumulative evidence suggests a
  correlation between EphA2 over-expression and clinical features of
  aggressive cancer. MEDI-547 is a result of MedImmune scientists
  utilizing technology licensed from Seattle Genetics.

NIJMEGEN, The Netherlands, January 6, 2009 — MedImmune, the global biologics unit of AstraZeneca, announced today that it has submitted a Marketing Authorisation Application (MAA) for its nasal spray live attenuated influenza vaccine (LAIV), which is now being reviewed by the European Medicines Agency (EMEA). The proposed indication in the MAA is for prevention of seasonal influenza.

The MAA submission for LAIV is based on data from 73 global clinical and U.S. post-marketing studies of more than 141,000 subjects ranging in age from 7 weeks to 97 years and conducted in 38 countries. Study objectives have included clinical safety and tolerability, clinical efficacy and effectiveness, and immunogenicity.

Influenza creates a heavy medical and economic burden on Europe and throughout the world, and we are hopeful that the future availability and product characteristics of this novel nasal spray influenza vaccine will contribute to an increase in vaccination rates and reduce the spread of influenza around the world, said Alex Zukiwski, M.D., executive vice president, clinical affairs and chief medical officer. MedImmune is pleased to submit this application for approval of our nasal spray influenza vaccine in Europe.

About LAIV
Each dose of LAIV is formulated to contain three live attenuated influenza virus strains, which are weakened as to not cause illness: Two Type A influenza strains (A/H1N1 and A/H3N2) and one Type B strain. The vaccine strains are selected annually by the World Health Organization (WHO) based on anticipated circulating influenza strains for the upcoming season. The vaccine is sprayed into the nose, rather than by injection as with other licensed influenza vaccines, where it induces protective immunity.

In the U.S., LAIV is marketed under the trade name FluMist® (Influenza Virus Vaccine Live, Intranasal). It was approved by the U.S. Food and Drug Administration in 2003. The vaccine included in the MAA has not been registered in the European Union (EU) and is not available outside of the United States.

About Influenza
Influenza is the most common vaccine-preventable disease in the developed world. According to WHO estimates, seasonal influenza results in three to five million cases of severe illness and up to half a million deaths globally each year, primarily among the elderly. Rates of infection are highest among children, with school-aged children significantly contributing to spread of disease to their families, communities and high-risk individuals.

Influenza also has socioeconomic consequences related to both direct and indirect health care costs, including hospitalizations, work absence and loss of work productivity when either a caregiver or child is sick with influenza.

In the EU, current guidelines recommend annual influenza vaccination for the elderly as well as those with underlying medical conditions such as chronic heart or lung disease. However, vaccination rates in the recommended groups throughout Europe are estimated to be only 35 percent (Ryan, Vaccine, August 2006).

To date, six EU countries (Finland, Austria, Estonia, Latvia, Slovakia and Slovenia) recommend routinely vaccinating young children against influenza with varying age limits. EU and Member State policymakers continue to evaluate data on the impact of influenza in children to best inform the potential expansion of recommendations.

MedImmune abstracts to be presented at ICAAC/IDSA on RSV include:

• Respiratory Syncytial Virus Therapy Utilizing Intranasally Delivered Motavizumab, a Monoclonal Antibody Against the Viral Fusion Protein (#V-4145) B. Richter, Tuesday, October 28, 2008, Hall C from 12:15 PM to 1:15 PM

BACKGROUND: A primary cause of pneumonia and bronchiolitis in young children is RSV infection. This preclinical study examined the therapeutic effect of topically administered motavizumab.

• Therapeutic Addition of Motavizumab, a Monoclonal Antibody Against Respiratory Syncytial Virus, Modulates Epithelial Cell Responses to RSV Infection (#V-4146) S. Krishnan, Tuesday, October 28, 2008, Hall C from 12:15 PM to 1:15 PM

BACKGROUND: RSV infection of epithelial cells leads to inflammatory host responses. This preclinical study tested whether motavizumab, a humanized monoclonal antibody against the RSV fusion (F) protein, could modulate epithelial cell immune responses to RSV. Lower and upper airway epithelial cells were infected with RSV and motavizumab or a control antibody was subsequently administered at various points post-infection to evaluate the therapeutic addition.

• Total Healthcare Costs of Preterm Infants with Medically Attended Respiratory Syncytial Virus Lower Respiratory Infection (#K-1429 ) D. Stewart, Sunday, October 26, 2008, Hall C from 12:15 PM to 1:15 PM

BACKGROUND: While RSV lower respiratory infection (LRI) is the most common cause of hospitalization among infants under one year of age, the total healthcare costs of medically attended RSV LRI for babies of this age group is unknown. This retrospective, propensity-matched cohort assessment sought to determine first-year healthcare costs by examining premature infants born over a five-year period who were insured by a national U.S. health plan, including a subgroup analysis of babies born between 33 and 36 weeks gestation.

• In Vitro Mechanism of Action Studies of the RSV-Neutralizing Monoclonal Antibodies Palivizumab and Motavizumab (#V-4146) K. Huang, Tuesday, October 28, 2008, Hall C from 12:15 PM to 1:15 PM

BACKGROUND: Synagis is the only licensed drug product available to help prevent lower respiratory tract RSV infection in premature infants, a leading cause of hospitalizations in this patient population. An affinity-optimized version of Synagis, motavizumab, has been subsequently developed. Since both Synagis and motavizumab bind the RSV fusion (F) protein, which plays a role in virus attachment and mediates the process of virus-cell fusion and cell-to-cell fusion, this study aimed to determine exactly how the drugs neutralize RSV. Four assays were used, which target four distinct steps during virus replication, to identify the mechanism.

• In Vitro and In Vivo Characterization of a Motavizumab-Resistant RSV A Mutant (#V-4148) F. J. Palmer-Hill, Tuesday, October 28, 2008, Hall C from 12:15 PM to 1:15 PM

BACKGROUND: This study investigated the growth characteristics – both in vitro and in vivo – of an RSV mutant that was created in the laboratory and is resistant to neutralization by motavizumab, an affinity-optimized MAb directed against the RSV fusion (F) protein. The F protein of the MAb differs from a wild type RSV F protein, so comparisons were made.

• Characterization of Respiratory Syncytial Virus (RSV)Mutants Resistant to Antibody Neutralization with Novel Amino Acid Changes in the RSV Fusion Protein (#V-4149) N. K. Patel, Tuesday, October 28, 2008, Hall C from 12:15 PM to 1:15 PM

BACKGROUND: Synagis is a MAb approved for the prevention of serious lower respiratory tract RSV infection in premature infants. Motavizumab was developed by affinity optimization of Synagis and is characterized by greater in vitro and in vivo neutralization activity against RSV. Previously, the selection of RSV mutants resistant to Synagis has been reported, characterized by amino acid changes in the RSV fusion (F) protein. This study sought to identify the selection and characterization of additional Synagis MAb-resistant mutants, as well as a novel motavizumab MAb-resistant mutant.

MedImmune abstracts to be presented at ICAAC/IDSA on influenza include:

• Influenza-like Illness and Employee Productivity – Results from the Child and Household Influenza-illness and Employee Function (CHIEF) (#K-4207) M. D. Rousculp, Tuesday, October 28, Room 150B from 2:450 PM to 3:00 PM

BACKGROUND: This prospective cohort study of nearly 2,293 U.S. households evaluated the effect of employee and household member influenza-like illness on worker productivity. The households studied were employees from three large Fortune 500 companies. All households included in the study had at least one child. Households were surveyed monthly throughout the 2007-2008 influenza season to determine the impact of influenza-like illness on employees’ work absenteeism and decreased productivity while on the job.

• Impact of Early and Late Influenza Vaccine Availability on In-Office Vaccination Opportunities (#G1-1208) R. Judelsohn, Sunday October 26, Hall C from 11:15 AM to 12:15 PM

BACKGROUND: The CDC now recommends all children from six months to 18 years of age receive an annual influenza vaccination; however, a key barrier to implementation is the inconvenience to parents and providers around scheduling additional office visits to administer the vaccination. This study examined how many more vaccination opportunities exist if influenza vaccination availability were expanded beyond the typical October-to-December timeframe.

• Benefits Versus Risks of Live Attenuated Influenza Vaccine (LAIV) in Young Children (#G1-1204) G. Oster, Sunday October 26, Hall C from 11:15 AM to 12:15 PM

BACKGROUND: In September 2007, approved use of LAIV in the U.S. was expanded to include children aged 24-59 months but with warning/precautions against use in younger children and children 24-59 months with a history of recurrent wheezing or asthma. Since some latter children may receive LAIV in clinical practice, its risks and benefits versus trivalent influenza vaccine (TIV) in this setting must be considered.

About Synagis
Synagis(R) (palivizumab) is indicated for the prevention of serious lung infections caused by respiratory syncytial virus (RSV) in children at high risk of RSV disease. Synagis is given as a shot, usually in the thigh muscle, each month during the RSV season. The first dose of Synagis should be given before RSV season begins. Children who develop an RSV infection while receiving Synagis should continue the monthly dosing schedule throughout the season. Synagis has been used in more than one million children in the U.S. since its introduction in 1998.

Synagis should not be used in patients with a history of severe prior reaction to Synagis or its components. Cases of severe allergic reactions such as anaphylaxis and other types of hypersensitivity reactions have been reported with Synagis. These reactions may occur when any dose of Synagis is given, not just the first one. Another serious side effect, which may lead to unusual bruising and/or groups of pinpoint red spots found on the skin, has been reported.

Most common side effects with Synagis may include upper respiratory tract infection, ear infection, fever, and runny nose. In children born with heart problems, Synagis was associated with reports of low blood oxygen levels and abnormal heart rhythms. Side effects, such as, skin reactions around the area where the shot was given (like redness, swelling, warmth, or discomfort) have also been reported.

About FluMist
FluMist(R) (Influenza Virus Vaccine Live, Intranasal) is a live attenuated influenza virus vaccine indicated for active immunization of individuals two to 49 years of age against influenza disease caused by influenza virus subtypes A and type B contained in the vaccine.

FluMist is contraindicated in individuals with history of hypersensitivity to eggs, egg proteins, gentamicin, gelatin or arginine or with life- threatening reactions to previous influenza vaccinations, and in children and adolescents receiving concomitant aspirin or aspirin-containing therapy.

Do not administer FluMist to children less than two years of age due to an increased risk of hospitalization and wheezing that was observed in clinical trials. FluMist should not be administered to any individual with asthma and to children less than five years of age with recurrent wheezing unless the potential benefit outweighs the potential risk. Do not administer FluMist to individuals with severe asthma or active wheezing.

If Guillain-Barre syndrome has occurred with prior influenza vaccination or if an individual is immunocompromised, the decision to give FluMist should be based on careful consideration of the potential benefits and risks. FluMist should not be administered to individuals with underlying medical conditions predisposing them to wild-type influenza infection complications unless the potential benefit outweighs the potential risk. FluMist should be given to a pregnant woman only if clearly needed.

Most common adverse reactions (occurring in 10 percent or more of individuals receiving FluMist and at a rate at least five percent higher than in those receiving placebo) are runny nose or nasal congestion in recipients of all ages, fever more than 100 degrees F in children two to six years of age, and sore throat in adults.

FluMist may not protect all individuals receiving the vaccine. FluMist is for intranasal administration only.

 All School-Age Children

GAITHERSBURG, Md., Aug. 4 /PRNewswire/ — MedImmune announced today that it began shipping FluMist(R) (Influenza Virus Vaccine Live, Intranasal) on July 31 for the 2008-2009 influenza season. Early and wide availability of FluMist is a key component in maximizing opportunities to vaccinate an additional 30 million children and teenagers through the age of 18 years who are now recommended by the U.S. Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices (ACIP) to be vaccinated annually against influenza.

(Photo: http://www.newscom.com/cgi-bin/prnh/20080804/NEM027 )

The CDC also advises that flu vaccine be administered every year as soon as it becomes available. Results of a recent analysis reported by MedImmune at the annual meeting of the Pediatric Academic Societies (PAS) revealed that starting vaccination against influenza in August may help reach an additional 10.7 million children while they are at healthcare provider offices for already-scheduled visits.

“To meet the goal of vaccinating every school-age child and teenager against the flu, vaccination practices must shift to include opportunities across a longer period of time,” said Norman “Chip” Harbaugh, M.D., F.A.A.P. of the Children’s Medical Group of Atlanta. “Early availability of FluMist gives providers the ability to reach more eligible children through back-to-school check-ups, sports physicals and annual well-child visits with a vaccine that has been shown to provide protection throughout the entire flu season.”

Record Number of FluMist Doses Available – and in More Locations

MedImmune will make FluMist more widely available than ever before, with plans to produce approximately 12 million doses for the 2008-2009 season. In addition to ongoing shipments to healthcare provider offices and clinics, FluMist will also be available this influenza season at select retail pharmacies and supermarkets. Please visit www.flumist.com for information about availability of FluMist in local areas.

FluMist will also be available in nearly 200 school-based vaccination programs and university health centers. Additionally, the U.S. Department of Defense (DoD) has awarded MedImmune a contract for FluMist for the fourth consecutive year to help vaccinate eligible active duty military personnel and their families.

FluMist is available in every state through the federally funded Vaccines for Children (VFC) program, which provides vaccines at no cost to eligible children. FluMist is also covered by approximately 94 percent of private health plans which offer immunization benefits.

FluMist is contraindicated in individuals with history of hypersensitivity to eggs, egg proteins, gentamicin, gelatin or arginine or with life-threatening reactions to previous influenza vaccinations, and in children and adolescents receiving concomitant aspirin or aspirin-containing therapy.

Do not administer FluMist to children less than two years of age due to an increased risk of hospitalization and wheezing that was observed in clinical trials. FluMist should not be administered to any individual with asthma and to children less than five years of age with recurrent wheezing unless the potential benefit outweighs the potential risk. Do not administer FluMist to individuals with severe asthma or active wheezing.

If Guillain-Barre syndrome has occurred with prior influenza vaccination or if an individual is immunocompromised, the decision to give FluMist should be based on careful consideration of the potential benefits and risks. FluMist should not be administered to individuals with underlying medical conditions predisposing them to wild-type influenza infection complications unless the potential benefit outweighs the potential risk. FluMist should be given to a pregnant woman only if clearly needed.

Most common adverse reactions (occurring in 10 percent or more of individuals receiving FluMist and at a rate at least five percent higher than in those receiving placebo) are runny nose or nasal congestion in recipients of all ages, fever more than 100 degrees F in children two to six years of age, and sore throat in adults.

FluMist may not protect all individuals receiving the vaccine. FluMist is for intranasal administration only.

In February, the Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices (ACIP) voted to expand flu vaccination recommendations to include all children six months through 18 years of age. Previously, the recommendations were for vaccination of children from six months to 59 months of age. The new guidelines add approximately 30 million children to the recommended pediatric population to be vaccinated annually against influenza.

“MedImmune is committed to doing all it can to support the ACIP’s expanded influenza vaccination recommendations and to work toward our common goal to vaccinate more children against the flu each year,” said John Trizzino, vice president, vaccines. “The data presented at the PAS meeting highlight the need to use every possible opportunity to improve vaccination rates and compliance, including vaccinating children when they visit their healthcare providers for back-to-school check-ups and sports physicals. We are focused on delivering FluMist(R) (Influenza Virus Vaccine Live, Intranasal) into the marketplace this year beginning in August.”

Earlier Influenza Vaccination Could Reach Nearly 11 Million More Children in Provider Offices

To examine the potential impact of early influenza vaccination, MedImmune researchers analyzed the Medical Expenditure Panel Survey (MEPS), a federally funded survey of families, individuals, and medical providers that collects data on health services utilized by Americans. They compared the number of children who had at least one healthcare provider visit between October 1 and December 31 (the traditional influenza vaccination period) to the number of children who had at least one visit between August 1 and December 31. The analysis found that by extending the flu vaccination season into August, an additional 6.6 million children would have vaccination opportunity during a well visit and 10.7 million children would have an opportunity to get a flu vaccine during an already-existing provider visit (well or sick).

Flu Vaccination Rates in Pediatrician Offices Remain Low

Another study, presented by Praful U. Bhatt, M.D. of Lock Haven, PA, assessed influenza vaccination use in pediatricians’ offices. Researchers selected a nationally representative sample of 44 pediatric practices in advance of the 2007-2008 influenza season. In these offices, the mean influenza vaccination rates were 37 percent in six to 23 month olds (1), 24 percent in 24 to 59 month olds, 19 percent in five to eight year olds, and 12 percent in nine to 17 year olds through February 29, 2008.

Additionally, the study looked at compliance with the recommendation that children younger than nine years of age who have not been previously vaccinated receive two doses of influenza vaccine at least four weeks apart. Compliance rates for receiving the second dose were 55 percent (six to 23 months) (1), 43 percent (24 to 59 months) and 25 percent (five to eight years of age).

The study also found that vaccination and compliance rates were higher in practices that administered influenza vaccine for more months during the vaccination season (starting earlier and ending later).

HONOLULU, May 5 /PRNewswire/ — Data from two new studies presented at the annual meeting of the Pediatric Academic Societies (PAS) demonstrate that FluMist(R) (Influenza Virus Vaccine Live, Intranasal) may offer children both durable protection against influenza, as well as significant protection for previously unvaccinated children who receive the recommended two-dose regimen approximately four weeks apart. In the efficacy trial evaluating one and two doses in previously unvaccinated children, protection was also observed among previously unvaccinated children who received only one dose of FluMist.

“These data add to the growing body of evidence that FluMist offers good protection against influenza for children eligible to receive it,” commented Chris Ambrose, M.D., director, medical affairs. “We hope that this data will help support public health efforts to encourage parents to vaccinate their children each year as soon as vaccine is available and follow dosing recommendations to optimally protect children against this infectious disease.”

FluMist is different from the flu shot in that it uses live, attenuated — or weakened — viruses within the vaccine to help stimulate an immune response that is designed to closely resemble the body’s natural response to an influenza infection.

Efficacy of FluMist Among Previously Unvaccinated Children

In a study involving 3,200 previously unvaccinated children between the ages of six (1) and 36 months, the efficacy of one dose of FluMist was compared to the recommended two doses. The study showed that for children receiving one dose of FluMist, efficacy against matched strains was 58 percent, and efficacy increased to 74 percent for those receiving two doses. In the second season of the study, both groups received a single dose of FluMist (per recommendations) and no difference in efficacy was seen (efficacies of 65 percent and 74 percent, respectively). Runny nose/nasal congestion and cough were the most frequently reported events. No events were significantly increased in FluMist recipients; cough was significantly decreased. This double-blind, placebo controlled study, led by Drs. Bracco and Farhat of the Federal University of San Paulo, Brazil, was conducted at 35 sites in the Southern Hemisphere during the 2001 and 2002 influenza seasons.

Dr. Ambrose stated: “Previously unvaccinated children under nine years of age are recommended to receive two doses of influenza vaccine, but studies have shown that less than 50 percent of these children actually receive the second dose. Our trial shows clear evidence that receiving the second dose of FluMist provides more robust protection. However, we are also encouraged that there was still protection for those that received one dose.”

Duration of Influenza Protection Using Nasal Spray Flu Vaccine

In a second study, researchers at MedImmune examined data from four previous clinical trials of children between six months (1) and 18 years of age and found that children who were given FluMist had a comparable level of protection through 12 months after vaccination.

“The data on FluMist’s duration of protection provide comfort for providers and parents who wish to vaccinate children in late summer or early fall,” said Ambrose.
