Potential Cancer Vaccine Entering Stage 3 Trials

Slashdot reader quonset writes: After decades of study and testing, a potential vaccine for cancer may be on the horizon. Dr. Thomas Wagner, founder of Orbis Health Solutions, is using the body's own immune system to fight the disease, with each shot personalized to the patient, according to ABC News. From the article:Typically, cancer cells evade a person's immune system because it is recognized as that person's cells. Wagner developed a tumor lysate particle only (TLPO) vaccine that uses a person's tumor cells to identify particular parts that are then presented back in the body using the vaccine in a way that can stimulate their immune system to gain the ability to detect these cancer cells like an infection, allowing the immune system to fight the cancer itself. "People used to ask me the question, 'When will there be a cure for cancer?' And I've been doing this for 60 years and I could never answer that question," Wagner said. "Until recently, until the last three or four or five years." Wagner believes this type of cancer treatment could be a key to finding the long-awaited cure for cancer, all cancers, if paired with early detection. Wagner's TLPO cancer vaccine has been tested in hundreds of patients with advanced forms of melanoma in Phase 2 clinical trials. The most recent data presented at an academic conference showed nearly 95% of people given only the vaccine were still alive three years after starting treatment and 64% were still disease-free. Among the most advanced forms of melanoma, disease-free survival after three years for people with stage III disease was 60% in the vaccine-only group, compared to about 39% in the placebo group. Disease-free survival for those with stage IV disease was about 68% in the vaccine-only group, and zero in the placebo group. The most common side effects were redness or pain at the injection site, fever and fatigue after the injection - similar to other vaccines that stimulate an immune response. Based on this data and other studies, the U.S. Food and Drug Administration has greenlit Wagner's vaccine to start a Phase 3 clinical trial. It will be a three-year endeavor with a goal to enroll 500 people and is planned to launch sometime this year, Riley Polk, president of Orbis Health Solutions, told WLOS, an ABC News affiliate in Asheville, North Carolina. Polk's own father was told there were no treatment options left for his lung cancer, according to the article. That was more than 10 years ago, and "His father opted to try Wagner's cancer vaccine and lived 10 more years before dying from something unrelated to cancer." Polk gives ABC News this quote. "You can tell me a lot of things, but you can't tell me [the vaccine] doesn't work."
