Clinical trials are medical studies or experiments done on actual human volunteers. These volunteers are subjected to a range of health risks, such as infection with viruses or disease-causing pathogens, medications, blood tests and other information that the researchers need to evaluate safely. However, clinical trials have been rigorously conducted and evaluated by medical professionals and the results of the trials have been widely published and made available to the general public. As long as the trial has been legitimate and reputable, many people feel safe taking the treatments recommended. However, as with any clinical research, there are certain instances when clinical trials can be fraudulent and the victims are the patients who took part in the clinical trials.
Types Of CRF Clinical Trials
One type of CRF clinical trials is known as the investigator-apprentice program. In this type of trial, the investigators recruit either the nurse the medical officer or the medical doctor as an assistant. Normally, these three individuals will be from the same clinical department or they may be from completely different departments. During the recruitment process, the candidates are asked to fill out a questionnaire covering various aspects of their nursing experience. The questionnaire also requires them to describe their previous clinical experiences and their current professional goals.
After filling out the questionnaire, the candidates proceed to participate in the clinical trials. In most instances, they will be given the option to choose to be a part of the placebo, the control group or the active group. However, there are some clinical trials wherein the candidates can choose to participate in only one of the three. Generally, participating in all three phases of the trial would increase the chances of receiving a particular treatment.
Another common scenario in clinical trials is the post-market phase. During this stage, the manufacturer may decide to discontinue the use of a particular treatment or to replace it with another medication. While this may be the preferred outcome for some, it may not always be the case. During the post-market phase, researchers continue to conduct tests on the new treatments and monitor the effects of long-term use.
To help in determining which clinical trials may prove useful in a patient’s treatment journey, it is important for doctors to assess the potential benefit of any treatment. This assessment should focus on what kind of symptoms the patient is experiencing. Although patients suffering from cancer often receive treatments based on their tumor, some symptoms do not always point to the presence of cancer cells. By evaluating these symptoms, doctors can determine whether the new treatment is suitable for a patient. It may take some time and money before researchers find the right combination of drugs to target the root cause of the problem.
One thing that all clinical trials share in common is the risks involved. Although the chances of finding the right combination are great, some new treatments carry similar risks to those of existing treatments. Some of these risks include allergic reactions, severe adverse events, infections and permanent damage to some organs or parts of the body. While these risks are rare, they are also real, which is why medical professionals must evaluate them before proceeding with a treatment.
