Clinical trials are the centerpiece for the drug-testing system in the United States.
Each cancer study conducted tries to answer scientific questions and determine better ways to prevent, diagnose or treat the disease. As researchers test the effectiveness of trial drugs, patients who participate, in many cases, benefit from life-saving treatment options years before they are available to the public.
Willamette Valley Cancer Institute and Research Center offer patients access to one of the nation’s largest research networks through participation in clinical trials through Sarah Cannon Research Institute (SCRI), a joint venture with US Oncology Research and one of the world’s leading oncology research organizations conducting community-based clinical trials.
Historically, in order to get the latest, greatest, most innovative care, someone had to go to a university; however, WVCI’s unique affiliation ables us to bring trials to patients in Eugene.
Focused on advancing therapies for patients over the last three decades, SCRI is a leader in drug development. It has conducted more than 600 first-in-human clinical trials since its inception and contributed to pivotal research that has led to the majority of new cancer therapies approved by the FDA today.
Clinical trials are conducted in a series of steps, called phases, and each phase is designed to answer a separate research question.
“If you go back just five, ten years, we would have said that phase I studies are really for patients who don’t have any other options,” says Dr. Jeff Sharman, Medical Director of Hematology for The US Oncology Network. “But we’ve now entered this new era where new drugs can be so effective, or reduce side-effects so much, that sometimes, phase I studies offer some great opportunities for cancer patients.”
A placebo-controlled trial is a study in which the effect of a drug is compared with the effect of a placebo (an inactive substance designed to resemble the drug). A common concern of patients considering a clinical trial is that they will receive a placebo instead of the drug being tested.
“Clinical trials do not necessarily mean placebo and in fact, placebo controlled studies are very rare in oncology,” says Dr. Sharman. “Randomized trials, however, are not rare.”
In a randomized controlled trial, participants are assigned by chance to separate groups that compare different treatments; neither the researchers nor the participants can choose which group. Using chance to assign people to groups means that the groups will be similar and that the treatments they receive can be compared objectively. At the time of the trial, it is not known which treatment is best.
Patients considering a clinical trial should know as much about it as possible, including what is being studied and what they can expect during the trial.
“What do we know about the drug? What are the side effects? Everything has side effects, but ask if those particular side effects are better than the alternative,” Dr. Sharman says.
