FDA bad news for snus?

Source: www.cspnet.com Author: staff The subject of putting tobacco under the control of the federal Food & Drug Administration (FDA) has divided the industry. Such regulation may also end product innovation, according to Forbes magazine. The report cites Reynolds American Inc.'s Camel Snus, the spit-free flavored pouch of pasteurized tobacco sold chilled in tins, as an example of the kind of innovation may be the last of its kind after this year's tobacco regulation bill, sponsored by Senator Edward Kennedy (D-Mass.), turns into law. The legislation is expected to easily pass through the Senate on Tuesday or Wednesday, after getting cleared by the House in April, and then quickly get a presidential signature. After test runs in Columbus, Ohio, and Portland, Ore., three years ago, R.J. Reynolds Tobacco Co., Winston-Salem, N.C., now sells Camel Snus in 100,000 locations nationwide. A tin of 15 costs $4.50. (Click here for previous CSP Daily News coverage.) The bill has divided the industry. Altria Group Inc., which makes market-leading Marlboro cigarettes though Phillip Morris USA, Richmond, Va., helped write the bill, which critics say will institutionalize that company's market share. The No. 2 tobacco maker, Reynolds American, which makes Camels through RJR, has been waging the battle against it. Altria is testing Marlboro Snus in Dallas and Indianapolis. (Click here for previous CSP Daily News coverage of Altria's other tobacco products strategy.) Kennedy's bill would allow the FDA to play gatekeeper to tobacco products like snus and newer smokeless tobacco lozenges and sticks. The [...]

DNA therapy for head and neck cancer

Source: Nature Reviews Clinical Oncology 6, 302 (June 2009) Author: Mandy Aujla Researchers have developed an antisense EGFR sequence to target EGFR, and found that this approach was safe and effective in patients with advanced squamous-cell carcinoma of the head and neck. Standard treatment for this type of cancer is suboptimal. Various drugs have been developed to block this increased signaling, such as cetuximab and erlotinib. These agents, however, have had limited success when used as monotherapy in treating squamous-cell carcinoma of the head and neck. Despite encouraging preclinical data these agents produce low response rates and are associated with toxic effects. Therefore, alternative approaches that target EGFR are needed. In this phase I trial, Lai and colleagues evaluated the safety and toxicity of EGFR antisense DNA therapy in 20 patients with advanced squamous-cell carcinoma of the head and neck. All patients included in the study had advanced disease that was unresponsive to standard therapies. The researchers tested six levels of the antisense EGFR at doses ranging from 60 to 1,920 g per injection, with three patients in each dose tier. The antisense EGFR was injected into the most accessible single tumor lesion once a week for 4 weeks. A biopsy was performed within 2 weeks of the final injection. A total of 17 patients completed the treatment course and were available for assessment. Of the five patients who achieved a clinical response, two had a complete response and three achieved a partial response. Two other patients had stable disease. [...]

New broad-spectrum vaccine to prevent cervical cancer induces strong responses in animals

Source: Journal of the National Cancer Institute Author: Staff Wednesday, May 27, 2009 Mice and rabbits immunized with a multimeric-L2 protein vaccine had robust antibody responses and were protected from infection when exposed to human papillomavirus (HPV) type 16 four months after vaccination, according to a new study published in the May 26 online issue of the Journal of the National Cancer Institute. Current HPV L1-based vaccines are almost 100% protective against infection by the two HPV types that are responsible for 70% of all cervical cancer cases world wide. However, the existing vaccines provide limited protection against the other HPV types that cause cancer. With that limitation in mind, Richard Roden, Ph.D., of the Johns Hopkins University in Baltimore, and colleagues have been working on an alternate vaccine that is based on the HPV minor capsid protein L2, which is highly conserved between HPV types. Previous experiments showed that the L2 protein induced only a weak antibody response in animals. In the current study, Roden and colleagues linked together a short segment of the L2 protein from several HPV types to generate a single multimeric L2 fusion protein. They tested the ability of this multimeric-L2 protein to induce antibody responses in animals and its ability to protect them from subsequent infection with HPV type 16. Mice immunized with the multimeric L2 vaccine developed robust antibody responses against all of the HPV types tested, although the antibody titer was still lower than the type-restricted responses following vaccination with an existing [...]

Trial shows cancer vaccine success

Source: Channel4news.com Author: Staff A vaccine against a sexually transmitted disease which causes most forms of cervical cancer can protect older women, according to a new study. Women aged from 24 to 45 who have not already been infected with the human papilloma virus (HPV) can be protected by the HPV vaccine, according to an article published in the medical journal The Lancet. HPV is a sexually transmitted disease which is responsible for most forms of cervical cancer. Trials were conducted with over 3,000 women in the relevant age group who had not been infected with HPV. Half were given a placebo and half were given a vaccine which protects against four strains of HPV. The researchers found that four cases of infection occurred in the vaccine group compared to 41 in the placebo group – meaning the vaccine was 91 per cent effective against all four virus strains. Looking at HPV 16 and 18 only, which are responsible for 70 per cent of cases of cervical cancer, four cases occurred in the vaccine group compared with 23 in the placebo group, meaning the vaccine was 83 per cent effective. When trials were conducted with women who had already been infected with HPV, the vaccine was only 30 per cent effective. The report's author, Dr Nubia Muñoz, therefore suggested that the public health benefit of vaccinating the older age group could potentially be less cost-effective than vaccinating teenagers who were less likely to have been sexually active. Currently teenage [...]

Induction chemotherapy followed by chemoradiotherapy increased time-to-treatment failure compared to chemoradiotherapy alone in patients with unresectable locally advanced head & neck cancer

Source: news.prnewswire.com Author: press release The Spanish Head and Neck Cancer Cooperative Group (TTCC) announced today that Induction Chemotherapy (IC) delivered prior to standard ChemoRadiotherapy (CRT), a treatment paradigm defined as sequential therapy, compared to upfront CRT alone, significantly prolonged Time-to-Treatment Failure (TTF) for patients with unresectable Locally Advanced Head and Neck Cancer (LAHNC). The endpoint of Time-to-Treatment Failure was defined as a composite of time-to-disease progression, -to-surgery or other cancer-related treatments, -to-drop-out due to an adverse event, and to death from any cause. Final results (abstract #6009) from the Phase 3 randomized study were presented by Prof. Ricardo Hitt, of the University Hospital 12 de Octubre, Madrid, in an oral presentation at the 2009 annual meeting of the American Society of Clinical Oncology (ASCO). The results of this study have also been selected for inclusion in the Best of ASCO(R) program. The Best of ASCO(R) is an educational initiative that condenses highlights from ASCO's Annual Meeting, with the objective of increasing global access to cutting-edge science that is relevant and significant in oncology today. This study enrolled 439 patients with Locally Advanced Head and Neck Cancer with good performance status, who were randomly assigned to receive standard CRT (cisplatin and fractionated radiation) versus the same treatment preceded by IC, which consisted of cisplatin plus 5-fluorouracil (5-FU) with or without Taxotere(R) (docetaxel) Injection Concentrate. The study was designed to compare the results of those patients who received IC prior to CRT (sequential therapy) and patients who received CRT alone. The [...]

New treatment combination proves safe for head and neck cancer patients

Source: www.eurekalert.org/pub_releases Author: press release Patients undergoing treatment for advanced head and neck cancers may respond well to the addition of gefinitib to chemotherapy, according to a study sponsored by the Eastern Cooperative Oncology Group and chaired by Ethan Argiris, M.D., associate professor of medicine, University of Pittsburgh School of Medicine, and co-leader of the Head and Neck Cancer Program of the University of Pittsburgh Cancer Institute (UPCI). The results will be disclosed at the 45th annual meeting of the American Society of Clinical Oncology (ASCO) on May 30 in Orlando, Fla. "We found that adding gefinitib to standard chemotherapy was well-tolerated by patients who had already received chemotherapy or were frail," said Dr. Argiris. "We had hoped this study would improve the survival rate of patients, but while gefinitib did postpone spread of the disease, it did not increase survival rates. The finding that the addition of gefinitib to chemotherapy can delay the growth of head and neck cancer suggests a potential beneficial effect from combination therapy." One group of 136 patients in the placebo-controlled study received docetaxel alone, a standard treatment for head and neck cancer. A second group of 134 patients received gefinitib in addition to docetaxel. This was the first phase III randomized trial to examine the addition of gefinitib to chemotherapy for patients with head and neck cancer. Gefinitib, which also is known by the trade name Iressa, is a targeted therapy against the epidermal growth factor receptor (EGFR) with fewer side effects than traditional [...]

Jeg Coughlin Sr. Chair filled by OSU’s Gillison

Source: Go2geiger.com Author: News Staff Leading human papilloma virus (HPV) expert Maura Gillison, MD, PhD, was officially named to the Jeg Coughlin Sr. Chair in Cancer Research during a special ceremony Wednesday night at the Longaberger Alumni House at The Ohio State University. "This is a dream come true for all of us," said Coughlin, who was surrounded by his four sons and many members of the extended Coughlin family. "This Chair represents a legacy that will continue forever. Cancer research takes commitment from a financial aspect and more importantly from a research and development side. Dr. Gillison has accomplished so many things already and we truly feel the best is yet to come." Gillison recently joined OSU's staff after a successful stint as associate professor at Johns Hopkins University School of Medicine in Baltimore, Md., where she was a member of the Sidney Kimmel Comprehensive Cancer Center. She now serves as professor of medicine in the division of hematology and oncology at OSU and is a member of the Cancer Control and Viral Oncology Programs at the Comprehensive Cancer Center. "Unfortunately, like so many other families, the Coughlins have been touched by cancer," Gillison said. "Now, they are a family on a mission. They put the same enthusiasm they bring to racing into cancer research. The Coughlin family has made it possible for me to take my research into a much broader direction and to really think outside of the box." Focusing on the role that [...]

R. J. Reynolds introducing ‘dissolvable’ tobacco

Source: KSPR News Author: News Staff Tobacco companies are facing new criticism, accused of targeting your kids. Not with ads, but with new types of tobacco products. Like Camel Snus, tea-bags filled with mint-flavored tobacco. R.J. Reynolds says Snus have become so popular, they're taking the next step -- totally dissolvable tobacco The company says it will solve all kinds of problems for traditional smokers. "They don't have second hand smoke. They don't have a litter problem. The product actually dissolves in your mouth as opposed to having to spit or extract something like a patch from your mouth like other smokeless products," says Tommy Payne of R. J. Reynolds. The company will soon test three new products: Camel Sticks that dissolve when you suck them, Minty Tobacco Strips that look like breath strips, and Orbs, flavored dissolvable tablets that some say look and taste like candy. Critics say R. J. Reynolds is doing what it did with Joe Camel -- marketing not to adult smokers, but smoker wanna-bes. "Really what you're doing with kids actually, it's kind of like a gateway drug. You're getting them addicted to nicotine, which then leads them to possibly wanting to do other things," says Dan Smith of the American Cancer Society. The Indiana Poison Control Center says just one Camel dissolvable delivers up to 300 percent of the nicotine found in just one cigarette. Take too many, and nicotine poisoning might set in, and you could develop oral cancer. R. J. Reynolds says [...]

U.S. cancer death rates continue to fall

Source: www.ajc.com Author: staff Some 650,000 people are alive today who wouldn't be were it not for advances in cancer prevention, detection and treatment over the past 15 years, new statistics show. The American Cancer Society's Cancer Statistics 2009 report finds an encouraging 19.2 percent drop in cancer death rates among men from 1990 to 2005, as well as an 11.4 percent drop in women's cancer death rates during the same time period. Overall, cancer death rates fell 2 percent per year from 2001 to 2005 in men and 1.6 percent per year from 2002 to 2005 in women. By comparison, between 1993 and 2001, overall death rates in men declined 1.5 percent per year and, between 1994 and 2002, 0.8 percent in women. "We continue to see a decrease in death rates from cancer in both men and women and this is mainly because of prevention - mostly a reduction in smoking rates; detection which includes screening for colorectal cancer, for breast cancer and for cervical cancer; and also improved treatment," said report author Ahmedin Jemal, strategic director for cancer surveillance at the American Cancer Society. "To put this in perspective, the number of lives saved is more than the population of Washington, D.C.," said Dr. Louis M. Weiner, director of the Lombardi Comprehensive Cancer Center at Georgetown University. "In my mind, that's a cause for some celebration. However, there are some sobering trends that we have to be aware of. The death rate for cardiovascular disease has dropped [...]

Majors to chew it over as big-league tobacco policy isn’t up to snuff

Source: www.nydailynews.com/sports Author: Filip Bondy Derek Jeter steps to the plate again, his jaw churning ferociously on some foreign, sticky substance. It’s just gum, and Jeter will prove that to the world now and then by blowing a giant bubble. But until the silly pink ball emerges, who knows? It might be gum, yet it also could be a pouch of smokeless or dip tobacco — that stubborn, traditional chew of choice for baseball players throughout history. And this is exactly what drives Jimmie Lee Solomon crazy, because sometimes he just can’t win. There are enough bad examples in his world. The executive VP of baseball operations for MLB worries that kids will get the wrong idea, and that baseball will be hurled back into the Nicotine Age. "It’s gum a lot of the time, not tobacco,"says Solomon, who has worked for 16 years to eliminate chewing tobacco and dip from the big-league culture. "Unfortunately, it can have the same, impressionable effect.” You know the most dangerous of all drugs in baseball? It isn’t steroids, and it isn’t human growth hormone. Those performance enhancers are health terrors in their own right, impacting the very bones of the game. But legal, smokeless tobacco in its multiple chewable forms still provides the addictive poisons linked most conclusively to illness and fatal disease. The Mayo Clinic identifies an assortment of horrors associated with chewing tobacco, whether it is packaged in the form of leaves, paste or twists: Tooth decay, gum disease, high blood [...]
