Gardasil Vaccine honoured with International Galien Prize for pharmaceutical research

Source: www.medicalnewstoday.com Author: staff Gardasil®, the four-type (6,11,16,18) human papillomavirus (HPV) vaccine, has been awarded the 2008 International Galien Prize, a prestigious award for recognising and promoting significant advances in pharmaceutical research which is considered the pharmaceutical industry equivalent of the Nobel Prize. "It is gratifying to be part of the transformation of scientific breakthrough into actual benefits for people's health," says Didier Hoch, President of Sanofi Pasteur MSD. "Only 30 years after the discovery that HPV can cause cervical cancer and many other diseases we hold today a vaccine in our hands that can save lives and prevent the suffering of thousands and millions of women. This is unprecedented progress in medical and pharmaceutical research." From 2006 to 2008, Gardasil® has won national Galien Prizes in Belgium, France, Netherlands, Switzerland, the US and the UK (the two HPV vaccines currently licensed for use in the UK were jointly awarded the Galien prize in the palace of Westminster, in September 2008). Additionally, Gardasil® has garnered a number of other prizes, including the 2006 Scrip Award by the British pharmaceutical newsletter Scrip for "Best new biological product" and 2007 Medec Prize by the French general practitioners for "Medicine of the year." During the 1970s, Professor Harald zur Hausen, the Co-Laureate of this year's Nobel Prize in Physiology or Medicine, postulated the role of HPV in causing cervical cancer. He pursued this idea for more than 10 years by searching for different HPV types, which culminated in the discovery in 1983 of [...]

HPV virus helps cervical and head and neck cancer grow and spread

Source: www.newswise.com Author: staff The human papillomavirus (HPV) allows infected cervical and head and neck cancer cells to maintain internal molecular conditions that make the cancers resistant to therapy and more likely to grow and spread, resulting in a poor prognosis for patients, researchers with UCLA’s Jonsson Cancer Center found. Virtually all human cancers experience a state called intratumoral hypoxia, or a low amount of oxygen within the tumor. In the UCLA study, researchers showed that the HPV-positive cancers adapted to and took advantage of the hypoxic environment by expressing a protein that activates a cell signaling pathway that helps the cancers survive, grow and spread. The study is published in the Nov. 4, 2008 issue of the journal Cancer Cell. The research, done on cells in culture and in animal models, may lead to the development of new therapies that target the cell signaling pathway, thereby interrupting ability of the cancer cells to thrive, said Dr. Matthew Rettig, senior author of the study and a researcher at UCLA’s Jonsson Comprehensive Cancer Center. “There is potential for therapeutic intervention based on this finding,” said Rettig, an associate professor of urology and medicine. The finding is crucial because 90 to 98 percent of cervical cancers are caused by HPV. Cervical cancer is the second most common cancer in women worldwide, with more than 500,000 cases diagnosed annually. In all, 200,000 women die from cervical cancer every year. In oral cavity and pharynx cancers, the HPV virus is linked to about 20 [...]

Oral rinses used for tracking HPV-positive head and neck cancers holds promise for cancer screening

Source: www.eurekalert.com Author: staff A study published in the journal Clinical Cancer Research, a journal of the American Association for Cancer Research, validates a non-invasive screening method with future potential for detection of human papillomavirus (HPV)-positive head and neck cancers. In the study, researchers at Johns Hopkins University used oral rinses and targeted DNA amplification to track and identify oral HPV infections in patients with HPV16-positive and negative head and neck carcinomas (HNSCC) before and after therapy. Findings showed detection of high-risk HPV infections in patients with HPV16-positive HNSCC for up to five years after therapy, indicating a high rate of persistent infection and reaffirming the connection between high-risk types of HPV and HPV-positive head and neck cancer. "There is no question of cause," said the study's co-author Maura Gillison, M.D., Ph.D. associate professor of oncology. "It has now become a question of tracking the infection over time to identify those at risk of developing HPV-positive cancer, and for those who have had it, the risk of recurrence and risk of transmission. This is the first study in which we have been able to track the disease and related oral infections for an extended period of time." Researchers obtained oral rinse samples from a group of 135 patients with head and neck carcinomas. Tissue analysis showed that 44 of these patients had HPV16-positive tumors. Both the tissue and oral rinse samples were genetically sequenced to specify the HPV variants in each. Patients with HPV16-positive tumors were significantly more likely to [...]

Nobel laureate calls for HPV vaccine for boys

Source: ww.xtra.ca Author: Andrew Innis The Nobel Prize winning pioneer of human papilloma virus (HPV) research is calling for the vaccination of boys against HPV. Speaking at the MaRS Centre in Toronto on Oct 21, Dr Harald zur Hausen argued that vaccination against the viruses, which can lead to cervical cancer in women, is also important to men since they too are susceptible to developing cancers related to HPV. Zur Hausen said men, like women, need to be protected from the more dangerous strains of the virus, HPV-16 and -18, which can contribute to the development of anal and penile cancer. The announcement came hours before the release of a report by the US Centers for Disease Control and Prevention (CDC), which confirmed that after two years of clinical usage Gardasil remains safe for human use, citing no elevated risk for neurological complications. The vaccine was approved for use in both Canada and the United States two years ago. Philippe Brideau, media relations officer for Public Health Agency Canada, said Gardasil has been found to be, “effective and the vaccine is safe, and should be used.” He said there have been no major reactions reported. Health Canada estimates nearly 75 percent of sexually active men and women will be infected with HPV at least once in their lifetime. While most strains of the virus are of little danger, mainly producing genital warts, it can lead to the development of cancer in both males and females. Men who have sex with [...]

Public knowledge and attitudes towards Human Papilloma Virus (HPV) vaccination

Source: 7th Space (Johns Hopkins Medical Letter) Author: Charlotte Devereaux et al. Human Papilloma Virus (HPV) vaccine has undergone successful trials and has recently been approved for use for the primary prevention of cervical cancer. The aim of this study was to determine knowledge and attitudes towards HPV vaccination. Method: Semi-structured interview and questionnaire delivered in a street survey. Standardised HPV-related statements used to measure HPV knowledge and attitudes to vaccination. The setting was three different areas of Birmingham, to target a mix of social class and ethnicity. The sample population was composed of 16-54 year olds. Results: A total of 420 participants were recruited. Poor knowledge of HPV and its links with cervical cancer were observed. 81% had a knowledge score of zero. Knowledge about HPV was associated with different ethnic group and socio-economic group. The majority (88%) of participants were in favour of vaccination, with 83.6% indicating that they would allow a child under their care to be vaccinated. Conclusion: Initial responses to the proposed HPV vaccination within the UK public are favourable. However, knowledge levels are poor and media and health professional promotion are required to raise awareness.

Cervical cancer vaccine called safe

Source: www.washingtonpost.com Author: staff Gardasil, the two-year-old vaccine that's designed to prevent cervical cancer, is safe, U.S. officials said Wednesday. The U.S. Centers for Disease Control and Prevention's Immunization Safety Office said a study of 370,000 doses given to girls and young women over the past two years found no evidence that the vaccine causes an increased risk of blood clots or other serious conditions, Bloomberg News reported. The CDC, which recommends the vaccine for girls starting at ages 11 and 12, based its findings on statistics from the Vaccine Safety Datalink, which uses medical data to test hypotheses about vaccine safety, the news service said. "There were no associations found that suggested an elevated risk," said John Iskander, acting director for the Immunization Safety Office, toldBloomberg. Critics of the vaccine, including some groups that worry that the inoculation could promote promiscuity, have contended that Gardasil may not be safe and could give women a false sense of security about sexually transmitted diseases. Gardasil protects against four types of genital human papillomavirus, HPV, which is spread through sexual contact and can cause cervical cancer in women. The U.S. study covered 190,000 girls and young women who received at least one dose of the vaccine's three-shot regimen. The CDC researchers compared medical data on those girls who got the vaccine with data for girls and young women who received other vaccines or none. "The results are really reassuring," said Dr. Paul Offit, chief of the infectious diseases division at Children's Hospital [...]

Mouth tumors increase; same virus causes cervical cancer

Source: The Oregonian (www.oregonlive.com) Author: Cynthia Billhartz Gregorian St. Louis Ten years ago, most of Dr. Brian Nussenbaum's oral cancer patients were men over 60 who used tobacco and drank heavily. Today, his patients with oral cancer look different. And so does the risky behavior that seems to be leading to their cancer. Nussenbaum, an ear, nose and throat doctor at Washington University, estimates that 70 percent of his cancer patients have tumors on the back of their tongues and tonsils caused by human papillomavirus-16. Most patients are between ages 45 and 55. About half are women. And experts suspect that all got the HPV from oral sex. "We know now that 98 percent of cervical cancer is caused by HPV, and mostly HPV-16," says Nussenbaum. "But no one talks about how you can also get mouth cancer from it." Last week, Dr. Harald zur Hausen, a German doctor and scientist, was awarded the Nobel Prize for medicine for finding human papilloma viruses that cause cervical cancer, the second-most-common cancer among women. In awarding zur Hausen the prize, the Nobel assembly said he "went against current dogma" in the 1970s when he discovered that certain types of HPV caused the cancer and that the DNA of HPV could be found in tumors. More than 20 years passed before researchers at Johns Hopkins Kimmel Cancer Center reported a link between HPV and these specific throat cancers in 2000. They and other medical experts suspect the increase in HPV oral cancer stems [...]

Sanofi Pasteur MSD’s HPV vaccine Gardasil(R) wins Prix Galien award

Source: www.medicalnewstoday.com Author: staff The two HPV vaccines currently licensed for use in the UK were jointly awarded the coveted Prix Galien Medal for Innovation at a ceremony held on Wednesday evening in the Palace of Westminster, House of Commons. "We are absolutely delighted at the recognition given to the world's leading HPV vaccine Gardasil® - this award reflects the work of many people, all around the world, involved in making the dream of a cancer vaccine a reality", said Dr Nicholas Kitchin, Medical Director, accepting the award on behalf of the Sanofi Pasteur MSD team. "Both companies have developed the technology of HPV vaccines down different paths," he continued, "we chose a quadrivalent vaccine strategy, targeting a broader range of HPV-related genital disease than cervical cancer alone, with the aim of delivering additional benefits for patients and healthcare systems." The joint award for the two HPV vaccines, developed by Sanofi Pasteur MSD and GSK, was presented by Andrew Lansley CBE MP, Shadow Secretary of State for Health. The distinguished panel of seven judges, chaired by Professor Sir Michael Rawlins, selected the HPV vaccines as the winners from seven innovative products that reached the final. Vaccines have won in four of the last five Prix Galien awards and the UK award for Gardasil® follows similar success in Prix Galien competitions in the USA and France. Current experience with the four-type HPV vaccine Thirty years after the discovery that human papillomavirus (HPV) can cause cervical cancer, 15 years after the start [...]

HPV increases men’s risk for oral cancer, prompts calls for vaccine: pathology expert Dr. Shashi Pawar on HPV health concerns for men

Source: www.prweb.com Author: press release HPV, the human papillomavirus, is well known for its role in causing cervical cancer in women - so much so, in fact, that the National Institutes of Health recommend all girls be vaccinated against the virus when they are 11 or 12, prior to becoming sexually active. However, recent research shows that women are not the only ones at risk for developing HPV-related cancers. Oral cancers caused by the virus are increasing rapidly in men, and researchers suggest HPV may soon overtake tobacco use as the leading cause of these cancers of the mouth, tongue, throat and tonsils. "The human papillomavirus is one of the most insidious and dangerous sexually transmitted diseases for women, as it has been linked to a vast majority of cervical cancers," explains Dr. Shashi Pawar, PhD, FACMG, Director of Genetics at Acupath Laboratories. "We are now seeing the effects of HPV infection in men, and the marked increase in oral cancer - coupled with the well-known increased risk for penile and anal cancers - suggests that both sexes face equally serious health consequences from this virus," Dr. Pawar notes. Cumulative research spurs call for men's vaccine A benchmark study that tracked more than 30 years of oral cancer data from the National Cancer Institute found that the rate of oral cancer caused by the HPV virus, rather than lifestyle habits such as smoking or chewing tobacco, has risen steadily since 1973 and is now about even with the incidence rate [...]

SensiGen HPV assay enables major breakthrough in diagnosis and treatment of head and neck cancer

Source: www.marketwatch.com Author: press release SensiGen LLC, a privately held biotechnology company focused on developing proprietary gene-based molecular diagnostic tests announced today a new program to make the Company's AttoSense(TM) HPV assay available to head and neck cancer researchers worldwide after recent studies showed that the success or failure of various treatment options (chemotherapy, radiation, extensive surgery) are largely determined by the viral load of Human Papillomavirus (HPV) in tissue samples from patients. These studies, carried out by the Head and Neck Oncology Team at the University of Michigan and published in the Journal of Clinical Oncology, demonstrate that head and neck cancer patients with higher concentrations of HPV, a virus long known to be associated with head and neck cancer, cervical cancer, and others, are much more likely to respond to organ-sparing chemotherapy than patients without high concentrations of the virus. This finding could offer significant hope for thousands of head and neck cancer patients facing uncertain and unpleasant treatments. "The data clearly show the importance of quantitative HPV testing in patients diagnosed with head and neck cancer," said Dr. Thomas Carey, leader of the University of Michigan based team that reported the breakthrough results this summer. "With the AttoSense(TM) HPV test and other biomarkers, we may soon be able to pinpoint the right therapy for each patient and maximize the chance of success on the first try, thus reducing the number of people who must endure multiple costly and uncomfortable treatments." SensiGen's AttoSense(TM) diagnostic assays are capable of [...]
