Vaccine clears some precancerous cervical lesions in clinical trial

Source: www.sciencedaily.comAuthor: Mark L Bagarazzi, MD et al. Scientists have used a genetically engineered vaccine to successfully eradicate high-grade precancerous cervical lesions in nearly one-half of women who received the vaccine in a clinical trial. The goal, say the scientists, was to find nonsurgical ways to treat precancerous lesions caused by HPV. "Every standard therapeutic option for women with these lesions destroys part of the cervix, which is particularly relevant for women of childbearing age, who may then be at risk for preterm birth due to a weakened cervix," says Cornelia Trimble, M.D., professor of gynecology and obstetrics, oncology, and pathology at the Johns Hopkins University School of Medicine, and first author of the new report, which appears online Sept. 17 in The Lancet. "A vaccine able to cure precancerous lesions could eventually be one way women can avoid surgery that is invasive and can also harm their fertility." High-grade cervical lesions, termed CIN2/3, occur most often in women 40 or younger, according to Trimble, a member of Johns Hopkins' Kelly Gynecologic Oncology Service and Kimmel Cancer Center. Because the lesions can progress to cancer, they are usually removed by surgery, freezing or laser. The procedures are successful in removing the precancerous areas in approximately 80 percent of women, says Trimble. Less troublesome lesions, called low-grade dysplasia, are usually monitored by physicians rather than immediately removed because they pose less of a risk for cancer and usually regress on their own. For the study, the scientists used a vaccine, originally developed [...]

FDA Grant Forwards Listeria-Based Throat Cancer Vaccine

Source: www.targetedonc.comAuthor: Sandra Kear An experimental immunotherapy for human papillomavirus-, or HPV-, related throat cancers, which is driven by the Listeria bacteria (that wreaks havoc when ingested), may now move forward due to a $1.1 million dollar grant from the FDA to researchers at Baylor College of Medicine. “Immunotherapy, such as axalimogene filolisbac, which targets HPV proteins expressed in cancer cells is a great example of using a cancer’s own unique biology against it.” said principal investigator Andrew Sikora, MD, PhD, leader of the head and neck cancer program in the NCI Comprehensive Designated Dan L. Duncan Cancer Center and an associate professor of otolaryngology at Baylor College, in an interview with Targeted Oncology. "This is hopefully the first step toward development of more targeted treatment approaches that reduce side effects and cancer treatment-related morbidity by uniquely targeting only virus-infected cells.”  The Listeria-based HPV immunotherapy, axalimogene filolisbac (ADXS11-001), is developed by Advaxis, and functions by stimulating an immune response against HPV proteins, thus killing infected cells. The drug is currently being evaluated in phase I-II study3 alone or in combination with MedImmune’s durvalumab, in patients with cervical or HPV-positive head and neck cancer. The study has three arms: axalimogene filolisbac alone, durvalumab alone, and the two drugs combined. Primary outcomes established for the study are: number of subjects with adverse events (AEs) in each dose level, number of subjects with AEs in the combination dose, and progression-free survival. Patients must have measurable disease by RECIST criteria, as well [...]

PLAINS - Tobacco use has been a big part of the rodeo for years; one participant of the Sanders County Fair is in the forefront of changing this, though, by promoting a tobacco-less lifestyle through the sport. Cody Kiser, a cowboy who rode bareback broncos at the Fair, has teamed up with the Oral Cancer Foundation’s ‘Be Smart, Don’t Start’ campaign to help teach kids about the dangers of tobacco products and oral cancer. According to their website, the campaign is part of the foundation’s rodeo outreach and attempting to “become engaged where the problem lives.” “While other [groups] are focused on getting users to quit, the Oral Cancer Foundation is reaching out to young people to not pick up the habit that they may see one of their rodeo heroes engaging in,” stated information provided by the OFC. To help with this, Kiser and the foundation have been working to present role models within the rodeo world who do not use tobacco products and actively advocate against their use. “How do you change that?” Kiser asked, regarding the tobacco-use culture. “I think that is in kids; you have to get to the kids and get their opinions changed.” The foundation’s main focus [...]

Raising awareness at the rodeo

Source: www.dailyrecordnews.comAuthor: Nicole Klauss A rodeo barrel racer from California is helping spread the word in Ellensburg that people shouldn’t start using tobacco. Carly Twisselman competed at the Ellensburg Rodeo slack Thursday night. She also helped share the message of the Oral Cancer Foundation, which is “Be smart. Don’t start.” While attending and competing at rodeo events, Twisselman reaches out to youth to encourage them not to pick up the habit they may see their rodeo heroes have. “The rodeo is known for having a lot of chewing tobacco. … The rodeo is such a small community and the heroes in it, the children look up to,” Twisselman said. “When they see their hero, growing up they think ‘I want to be like them.’” Campaign The Oral Cancer Foundation teamed up with Twisselman and bareback bronc rider Cody Kiser to spread the word in the rodeo circuit. The goal of the campaign is to spread awareness of oral cancer and the dangers of starting tobacco use. Twisselman often spends time talking to children and hands out buttons and bandannas to spread the message. Smokeless/spit tobacco is one of the historic causes of deadly oral cancers, and is more addictive than other forms of tobacco use, according to a news release from the Oral Cancer Foundation. According to the Oral Cancer Foundation’s website (www.oralcancer ocw.upc.edu.org), mouth cancers are newly diagnosed in about 115 people each day in the U.S., and worldwide new mouth cancer cases exceed 450,000 annually. When found at [...]

An HPV-E6/E7 immunotherapy plus PD-1 checkpoint inhibition results in tumor regression and reduction in PD-L1 expression

Source: www.nature.comAuthor: A E Rice, Y E Latchman, J P Balint, J H Lee, E S Gabitzsch and F R Jones We have investigated if immunotherapy against human papilloma virus (HPV) using a viral gene delivery platform to immunize against HPV 16 genes E6 and E7 (Ad5 [E1-, E2b-]-E6/E7) combined with programmed death-ligand 1 (PD-1) blockade could increase therapeutic effect as compared to the vaccine alone. Ad5 [E1-, E2b-]-E6/E7 as a single agent induced HPV-E6/E7 cell-mediated immunity. Immunotherapy using Ad5 [E1-, E2b-]-E6/E7 resulted in clearance of small tumors and an overall survival benefit in mice with larger established tumors. When immunotherapy was combined with immune checkpoint blockade, an increased level of anti-tumor activity against large tumors was observed. Analysis of the tumor microenvironment in Ad5 [E1-, E2b-]-E6/E7 treated mice revealed elevated CD8+ tumor infiltrating lymphocytes (TILs); however, we observed induction of suppressive mechanisms such as programmed death-ligand 1 (PD-L1) expression on tumor cells and an increase in PD-1+ TILs. When Ad5 [E1-, E2b-]-E6/E7 immunotherapy was combined with anti-PD-1 antibody, we observed CD8+ TILs at the same level but a reduction in tumor PD-L1 expression on tumor cells and reduced PD-1+ TILs providing a mechanism by which combination therapy favors a tumor clearance state and a rationale for pairing antigen-specific vaccines with checkpoint inhibitors in future clinical trials. *This news story was resourced by the Oral Cancer Foundation, and vetted for appropriateness and accuracy.

Boston votes to ban chewing tobacco from ballparks, including Fenway

Source: www.washingtonpost.comAuthor: Marissa Payne Baseball in Boston is about to change. On Wednesday, the City Council voted unanimously to make its baseball parks and stadiums, including historic Fenway, tobacco-free zones. And yes, the ordinance covers the kind of tobacco you chew, a longtime favorite of many MLB players. “This action will save lives by reducing the number of young people who begin to use smokeless tobacco because they followed the example of the Major Leaguers they idolize,” Matthew Myers, president of the Campaign for Tobacco-Free Kids said in a statement sent to The Washington Post. “We thank Mayor Marty Walsh, the City Council and Boston’s health community for their leadership on this important issue.” Red Sox owner John Henry was also supportive of the legislation. “It’s a great thing,” Henry said (via Boston.com) when Mayor Walsh first proposed the legislation last month. “I’m very supportive.” The ban doesn’t just apply to players, but also fans, and it covers all stadiums from major-league to organized amateur games. Those found in violation of the ordinance face a $250 fine, Boston’s Fox affiliate reports. Boston is now the second major U.S. city to ban tobacco at its baseball stadiums. San Francisco, which banned the substance in April, was the first. Both cities had very good reasons to nix the chew. Smokeless tobacco, like cigarettes, contains the addictive substance nicotine and its users can become more at-risk for illnesses such as cancer, gum disease and heart disease, according to the Mayo Clinic. “You can call chewing tobacco by [...]

Teen E-Cig Users More Likely to Smoke

Source: www.newswise.com Newswise — As e-cigarette usage among high school students continues to climb, a recent study from The Journal of the American Medical Association reveals an unsettling trend: that adolescent e-cigarette users are more likely than their non-vaping peers to initiate use of combustible tobacco products such as cigarettes, cigars and hookahs. The reason may lie in a common denominator between e-cigarettes and their combustible counterparts: nicotine. While the study hints that more research is needed to determine if this association is merely casual, it’s important to note that while e-cigarettes don’t contain tobacco, the battery-powered devices do deliver nicotine in aerosol form. “Nicotine’s addictive properties are a risk for any age group, but with adolescents, the stakes are even higher,” says Dr. K. Vendrell Rankin, director of Texas A&M University Baylor College of Dentistry’s Tobacco Treatment Services. For teens, mental health as well as key emotional and cognitive systems are at stake. “Major cognitive functions and attention performance are still in the process of developing during adolescence,” says Rankin, also a professor and associate chair in public health sciences at TAMBCD. “Nicotine increases the risk of developing psychiatric disorders and lasting cognitive impairment and is associated with disturbances in working memory and attention. Reliance on nicotine to manage negative emotions and situations impairs the development of coping skills.” In addition to affecting the emotional and cognitive development of teens, nicotine is highly addictive. In fact, the younger a person is when they begin using nicotine, the more likely they [...]

Rodeo Competitor Speaks to Youth to Spread Anti-Tobacco Message

Source: www.prnewswire.comAuthor: Oral Cancer Foundation Cody Kiser prepares for competition while sporting the Oral Cancer Foundation's message - Be Smart. Don't Start. NEWPORT BEACH, Calif., Aug. 14, 2015 /PRNewswire-USNewswire/ -- The traditional image of the American cowboy is one of strength, rugged determination and courage. In the world of professional rodeo competition, that image is no different. Cowboys—and increasingly so cowgirls—are held in esteem and looked at as heroes by young and old alike. The power of the cowboy as a compelling figure has not gone unnoticed by the tobacco industry, whose marketing campaigns have sought to tie the ideals of the cowboy with the use of their products. The western/rodeo environment in the US has had a long-term relationship with tobacco, and until 2009 The Professional Rodeo Cowboys Association (PRCA) and the rodeos that they sanctioned had a lengthy history of tobacco money funding the sport. While that has ended at PRCA events, tobacco use and smokeless/spit tobaccos are still popular within the sport. The Oral Cancer Foundation (OCF) believes that in order to solve problems you must engage the problem at the source. As a small and growing non-profit, OCF is not afforded the luxury of relying on conventional methods of outreach utilized by larger, more established charities. To enact meaningful change and bring awareness to the public, OCF must employ ingenuity and creativity to address the problems at hand. Within the world of professional rodeo, that problem remains to be the glorification and pervasive use [...]

AstraZenica, Inovio strike deal to find HPV cancer vaccine

Source: www.philly.comAuthor: David Sell Local drugmakers - big and small - struck a deal to try to develop a vaccine to prevent a form of cervical, head and neck cancer. MedImmune, which is the biologics and research division with AstraZeneca, said Monday it will collaborate with Inovio Pharmaceuticals to develop an early stage cancer vaccine designed to treat human pappilomavirus. AstraZeneca will pay Inovio $27.5 million upfront. If the compound reaches development and commercial milestones, Inovio could get up to $700 million, along with "double-digit tiered royalties" on product sales. However, sales are a long way off because the compound is only in phase I and phase II of what is normally a three-phase clinical trial process. AstraZeneca is moving its headquarters from London to Cambridge in the United Kingdom, and has operations in Wilmington and Fort Washington. The MedImmune division is headquartered in Gaithersburg, Md. Inovio is based in Blue Bell and its basic scientific premise is to use DNA to develop vaccines. unlike most current vaccines. The companies have worked together before. The compound at the heart of the latest deal is called INO-3112. The early clinical trials are examining cervical and head and neck camcers and the compound tries to generate "killer T-cell responses that are able to destroy HPV 16- and 18- driven tumors. These HPV types are responsible for more than 70 per cent of cervical pre-cancers and cancers, " according to the statement. The full statement from AstraZeneca is here. *This news story was [...]

Riders raise awareness for oral cancer

Source: Millard County Chronicle ProgressAuthor: Doug Radunich Two traveling rodeo riders helped raise awareness for oral cancer at the Days of the Old West rodeo in Delta June 11-13. As a non-profit seeking to spread awareness of oral cancer and the dangers of starting terrible tobacco habits, the foundation teamed up with bareback bronco rider Cody Kiser, of Carson City, Nev., and barrel rider Carly Twisselman, of Paso Robles, Calif., in an effort to spread the word among the Rodeo circuit, which is one of the biggest arenas of tobaccos-using patrons. While others are focused on getting users to quit, the Oral Cancer Foundation is encouraging young people to avoid the habit that they may see one of their rodeo heroes engage in. The message of the foundation is simple and not confrontational: "Be Smart. Don’t Start". This message was displayed at the recent rodeo in Delta. Also at the Delta rodeo, Kiser and Twisselman sported Oral Cancer Foundation logos and wording on their clothes and riding gear, while handing out free buttons, wristbands and bandanas. Both riders also gave autographs, talked and had pictures taken with young fans. Both riders, who will promote the message at different rodeos across the country, also competed in their respective riding events while in Delta. “It’s an awesome opportunity to use our platform, and it’s for a good cause and to put good message out there,” Twisselman said. “There are family members and friends and peers out there who chew tobacco, and in the [...]
