Researchers take head and neck cancer by the throat

Source: www.brisbanetimes.com.au Author: Stuart Layt Research has identified more weak spots in a deadly type of head and neck cancer that it is hoped will lead to more effective treatments. Oropharyngeal cancer can affect the base of the tongue, the tonsils, soft palate and parts of the throat, and almost half of all cases in Australia are caused by the human papillomavirus (HPV). Current immunotherapies target two protein receptors on the cancer; however, they have had mixed success. Lead researcher Professor Rajiv Khanna from QIMR Berghofer said they had identified four more spots on the genome of the cancer that they believed could be targeted by immunotherapy. “Everybody has been trying to make immunotherapies that target those two antigens, but what we have found is that while those two are important, we were ignoring some of the other antigens,” Professor Khanna said. “We took immune cells out of our patients and effectively asked them what they could “see” other than [the two proteins] E6 and E7, and actually they could see others.” The study analysed immune cells taken from 66 oropharyngeal cancer patients at the Royal Brisbane and Women’s Hospital and the Princess Alexandra Hospital. Co-lead author Professor Sandro Porceddu, the director of radiation oncology research at the Princess Alexandra Hospital, said they were now developing therapies based on the research. “We’re already working on developing better killer T-cell immunotherapies that recognise all, or a combination, of these proteins,” Professor Porceddu said. “Different combinations of the proteins are present on [...]

Novel vaccine therapy can generate immune responses in patients with HPV-related head and neck cancer

Source: www.news-medical.net Author: staff A novel vaccine therapy can generate immune responses in patients with head and neck squamous cell carcinoma (HNSCCa), according to researchers at the Abramson Cancer Center of the University of Pennsylvania. The treatment specifically targets human papillomavirus (HPV), which is frequently associated with HNSCCa, to trigger the immune response. Researchers will present the results of their pilot study during the 2017 American Society of Clinical Oncology Annual Meeting in Chicago (Abstract #6073). HNSCCa is a cancer that develops in the mucous membranes of the mouth, and throat. While smoking and tobacco use are known causes, the number of cases related to HPV infection - a sexually transmitted infection that is so common, the Centers for Disease Control says almost all sexually active adults will contract it at some point in their lifetimes - is on the rise. The CDC now estimates 70 percent of all throat cancers in the United States are HPV-related. Sixty percent are caused by the subtype known as HPV 16/18. "This is the subtype we target with this new therapy, and we're the only site in the country to demonstrate immune activation with this DNA based immunotherapeutic vaccine for HPV 16/18 associated head and neck cancer," said the study's lead author Charu Aggarwal, MD, MPH, an assistant professor of Hematology Oncology in the Perelman School of Medicine at the University of Pennsylvania. The vaccine is delivered as an injection of antigens - which leads the immune system to start producing antibodies and [...]

Merck KGaA, Pfizer and Transgene team up on cancer vaccine

Source: www.biopharmadive.com Author: Joe Cantlupe Dive Brief: Transgene announced Tuesday it is teaming up with Merck KGaA of Darmstadt, Germany, and Pfizer to evaluate the possibilities of the combination of its human papillomavirus (HPV)-positive head and neck cancer vaccine TG40001 with big pharma’s avalumab in a Phase 1/2 study. The incidence of HPV-related head and neck cancers has increased significantly, with one variation, HPV-16 accounting for 90% of all HPV-related head and neck cancers. HPV-16 is a subset of head and neck squamous cell carcinoma (HNSCC), a group of cancers that can affect the mouth and throat. Global spending on head and neck cancer indications amounted to $1 billion in 2010, according to the companies’ recent estimates. Current treatments for the disease include surgical resection with radiotherapy or chemo-radiotherapy; the companies say they are exploring better options for advanced and metastatic HPV and HNSCC. Dive Insight: The current deal between the big pharma partners and Transgene highlights the industry's efforts to create combination therapies to treat cancer. Virtually every company in the space has embraced the idea that using multiple modes of attack could be the only way to eventually find cures for the many forms of cancer; companies have been teaming up in hopes of finding that crucial pairing. In previous clinical trials, TG4001 has demonstrated promising activity in terms of HPV viral clearance and was well tolerated, according to Transgene. TG4001 is one of the few drugs targeting HPV-associated cancers that can be combined with an immune checkpoint [...]

Major study finds no link between vaccines and autism

Source: therawstory.comBy: Agence France-Presse Date: Friday, March 29, 2013 A US study out Friday sought to dispel the fears of about one third of American parents that giving a series of vaccines to children may be linked to autism. Even though children are receiving more vaccines today than they did in the 1990s, there is no link between “too many vaccines too soon” and autism, said the study in the Journal of Pediatrics. About one in 10 US parents refuse or delay vaccinations for their children because they believe it is safer than following the schedule put out by the Centers for Disease Control and Prevention, according to previous research. Prior studies have already shown there is no link between vaccines and autism, including a 2004 comprehensive review by the Institute of Medicine. This time, researchers at the CDC decided to look children’s exposure to antigens, the substances in vaccines that cause the body to produce antibodies to fight infection and disease. Researchers looked at data from 256 children with autism spectrum disorder across three separate managed care organizations in the United States. They compared the cumulative exposure to antigens in those children to 752 children without autism. “We found no evidence indicating an association between exposure to antibody-stimulating proteins and polysaccharides contained in vaccines during the first two years of life and the risk of acquiring autism spectrum disorder, autism disorder or autism spectrum disorder with regression,” said the study. Nor were there any links between autism and cumulative [...]
