Who Can Handle And Conduct Clinical Trials?
ClinicalResearch trials are observations or experimental studies conducted on aspecific number of test subjects to determine the safety profile of a new drug,medical device, or treatment designed for a particular disease. These studiesgenerate data on the efficacy of a drug or treatment and are performed by theassociates that are given the best clinical research training. As these studies are experimental, they have manyrisks associated with them.
Clinicaltrials are very carefully designed in an orderly manner, reviewed, andcompleted. These have to be approved by the respective authorities before theycan start. Based on the type of treatment, age groups are chosen to take partin these trials. These trials have to strictly adhere to protocol and withexcellent patient counseling to achieve the expected outcomes.
There are four phasesin every clinical trial. These phases are:
- Phase I: This includes the studies of the test conducted by the new drugs for the first time on a very small group of individuals. It is done to evaluate the safety profile, and dosage ranges, and the adverse effects of the drug.
- Phase II: This phase studies the test treatments that were found to be safe in Phase I. This phase includes a larger group of test subjects to monitor them with respect to the adverse effects of the drug.
- Phase III: The studies of this phase are conducted on a large population in different regions of different countries. It is often considered to be the actual first step in drug or treatment approval.
- Phase IV: These studies are generally conducted after country approvals, and there is a strong need for further testing in larger or wider populations. It is done in a larger time-frame on a mass population.
Who participates in clinical trials?
Theset protocols determine who can take part in clinical trials. Every clinicaltrial has set protocols set based on certain criteria. This criterion is solelybased on the objectives of the clinical trial. The possible criteria mayinclude the possible illness or condition and being healthy without thespecific condition. The exclusion criteria are the factors that restrict peoplefrom taking part in the trial.
Thereare several non-specific reasons for a participant to participate in a clinicaltrial. Being a part of a clinical research trial enables the participants totry new treatments before they are widely available. After a participant signsthe consent form, they shall be screened by the clinical staff andprofessionals to verify if that participant meets all the required criteria tobe an active part of the clinical research trial. This form of screeninggenerally involves cognitive and physical tests.
Alarge volume of participants is screened to find enough people meeting all therequirements for the trial. As the eligibility criterion varies from trial totrial, exclusion from one trial does not exclude other trials.
Allclinical trials must have a diverse group of participants. The participants aregenerally a group of individuals of different ethnicities, ages, races, andsexes. If a particular trial is conducted on similar people, the treatment ordrug may not benefit everyone.
Who conducts clinical trials?
Clinicalstudies and clinical research trials are generally conducted by a principalinvestigator who is generally a medical professional. These studies aregenerally led by a research team that includes doctors, nurses, social workers,volunteers, and other healthcare professionals.
Clinical Research Courses are sponsored or funded by academic medical centers,pharmaceutical companies, government organizations, volunteer organizations,etc. These clinical research studies can occur in many locations, includinghospitals, universities, community clinics, etc. It is dependent on who isconducting and sponsoring the trial.
TheFDA and other concerned authorities are committed to protecting theparticipants of the clinical trials. They also provide reliable information tothose willing to participate as test subjects in these trials. The concernedauthorities ensure that all the protocols are rigid and are complied with tomake sure that no harm comes to the test subjects of the trial. Any form ofunethical behavior results in complete shut-down with strict actions takentoward the clinical trial hosts.
Althoughthey are made to minimize the risk associated with clinical trials, some risksare completely unavoidable. It is because these trials are experimental and mayhave unexpected reactions. All the test subjects need to understand theprocedure and protocols and the expected side-effects and situations of unsayablecircumstances before deciding to take part in these trials.
Thereare several ways to find out about on-going clinical research trials. Yourdoctors and healthcare providers can give you information regarding on-goingtrials. One takes an active role in their healthcare by taking part in thesetrials. They also contribute to the betterment of the overall health of theworld by taking part in these trials. These trials are certainly beneficial toall of mankind as they help eradicate illnesses one step at a time.
