Clinical trials are designed to evaluate the safety and efficacy of treatments in humans, which requires testing them in a living, functioning organism. Human tissue samples cannot explain how a treatment affects the whole body, including its absorption, distribution, metabolism, and excretion. Additionally, clinical trials allow researchers to monitor for adverse effects due to the treatment, which cannot be assessed in tissue samples alone.

What must a clinical trial involve?
Clinical trials include tests of new drugs or medical treatments in human subjects to see if they are safe and if they work.human beings as subjects.
What is the main reason that preclinical study should be performed before the clinical one?
Preclinical studies are done to assess the safety and effectiveness of a drug or therapy in animal models before testing in humans. This helps identify potential risks, determine appropriate dosages, and optimize the study design for clinical trials. Conducting preclinical studies can help ensure that only the most promising candidates progress to human trials, ultimately enhancing the chances of success in clinical development.
What is human tissue?
Human tissue refers to groups of cells that are similar in structure and work together to perform specific functions in the body. Examples of human tissues include muscle tissue, nervous tissue, and connective tissue.
What is the most dense tissue in the human body?
The most dense tissue in the human body is bone tissue. It is composed of mineralized collagen fibers that give it its strength and hardness, making it the densest tissue in the body.
Is muscle considered an organ or tissue in the human body?
Muscle is considered a type of tissue in the human body, not an organ. Organs are made up of different types of tissues, including muscle tissue.
Why clinical trials can't be done on human tissues?
The tissue samples are not alive. They are not living or moving like a living human. The effects of the drugs may be different on 'non living' samples may be different to the effects on a non-living human.
Why can't clinical trials be done on human tissue samples only?
The tissue samples are not alive. They are not growing/moving like a living human so the effects the drugs have on the non living samples may be different to the effects on a living human.
What is a cytogeneticist?
Clinical cytogeneticists are experts in studying chromosomes from samples of human blood, tissue, bone marrow or other bodily fluids, which is very important in diagnosing genetic diseases.
Who is a clinical trial restricted by ethics?
It involves a human patient.

What is Clinical Trails?
Clinical trial is any research study that prospectively assigns human participants or groups of humans to one or more health-related involvement to evaluate the effects on health outcomes. Clinical research trials may be conducted by government health agencies such as NIH (National Institute of Health), researchers affiliated with a hospital or university medical program, independent researchers, or private industry. Clinical trial interventions include but are not restricted to: Experimental Drugs Cells and Other Biological Products Vaccines Medical Devices Surgical and Other Medical Treatments and Procedures Psychotherapeutic and Behavioural Therapies Health Service Changes Preventive Care Strategies and Educational Interventions. Researchers may also conduct clinical trials to evaluate diagnostic or screening tests and new ways to detect and treat disease. Types of Clinical TrialsThere are two main types of clinical trials: Observational clinical trials do not test drugs or treatments. Researchers observe participants by monitoring their health over a period of time. These studies provide researchers with data that advances our understanding of Parkinson’s and how to treat the disease. Interventional clinical trials test the safety and effectiveness of a candidate drug, therapy or experimental treatment. Clinical trials also can be classified as follows: Treatment trials Prevention trials Screening trials Quality of Life trials Genetics trials Phases in Clinical Trials: Phase 0: Number of Subjects (10-15) Phase I: Screening for safety: Number of Subjects (20-80) Phase II: preliminary efficacy of the drug: Number of Subjects (100-300) Phase III: Final confirmation of safety and efficacy: Number of Subjects (1000-3000) Phase IV: Post marketing studies.
