SUMMARY: Clinical Trials—what are they?
If you are a PC newcomer and have never previously dealt with a major medical issue, then you probably have no idea what a Clinical Trial is. This posting will give you plenty of info to get you started. Before you start any treatment, it might be worth looking into whether you are eligible to receive a higher level of care through a Clinical Trial…
This posting is appropriate for
all newly diagnosed men, regardless of which risk group you are in (HIGH-RISK, INTERMEDIATE-RISK or LOW-RISK).
What is a Clinical Trial? A clinical study involves research using human volunteers (also called participants) that is intended to add to medical knowledge. Participants receive specific interventions according to the research plan created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or changes to participants' behavior, for example, diet. Clinical trials may compare a new medical approach to a standard one that is already available or to a placebo that contains no active ingredients or to no intervention. The investigators try to determine the safety and efficacy of the intervention by measuring certain outcomes in the participants — their disease or condition, how they react to the treatment, and potential side effects, which will be monitored.
Who conducts Clinical Trials? Every clinical study is led by a principal investigator, who is often a medical doctor. Clinical studies also have a research team that may include doctors, nurses, social workers, and other health care professionals. Clinical studies can be sponsored, or funded, by pharmaceutical companies, academic medical centers, voluntary groups, and other organizations, in addition to Federal agencies such as the National Institutes of Health, U.S. Department of Defense, and U.S. Department of Veterans Affairs. Physicians, health care providers, and other individuals can also sponsor clinical research.
Are Clinical Trials only for advanced cases? No, definitely not, although it is true that most trials for new drugs are for advanced, HIGH-RISK cases. A sampling of Clinical Trials which are currently recruiting for INTERMEDIATE-RISK or LOW-RISK men with PC include (but not limited to) these Trial titles (from
clinicaltrials.gov):
· Diet in Altering Disease Progression in patients with PC on ACTIVE SURVEILLANCE (AS)
· AS for cancer of the Prostate (ASCaP)
· AS in PC
· Shared decision making in LOW-RISK PC
· Study of Antioxidants on prostate tumors in men undergoing RP for PC
· Quality of Life Study for PC patients
· Guided biopsy for mapping PC
· MRI in Diagnosing PC
· Impact of F-18 PTE/CT and MR Imaging in Management of Primary PC
· Anxiety in men with PC
· Efficacy and safety study of TOOKAD Soluble for localized PC compared to AS
· HIFU in treating patients with localized PC
· Stereotactic Hypofractionated Radiosurgery for Early Stage PC
What are the benefits of participating in a Clinical Trial? The key benefit is the opportunity to receive the latest and best treatment available. Patients receive either the best standard treatment (control group) or an additional treatment (test group) that may be more effective (and not generally available to others). People who enroll in these studies often get more frequent oversight & follow-up from doctors.
Tell me more about the use of placebos. A placebo-controlled trial compares a new treatment with a placebo; people who receive a placebo are in the control group. The use of placebos in cancer clinical trials is generally rare, but is an important component of the new “targeted” drugs being developed for prostate cancer so that researchers can tell whether stabilization of the tumor growth is an effect of the treatment or just reflects the natural behavior of the tumor.
Is it easy or difficult to enter a Clinical Trial? “Both” is probably the best answer. 80% of clinical trials fail to enroll the required number of patients on time, so many are looking for patients. On the other hand, the medical criteria is usually very strict because a valid scientific conclusion can only be reached if all the patients have similar medical conditions/requirements.
