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 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.
When are researchers specifically required by NIH policy to describe Data and Safety Monitoring?
Researchers are required to describe Data and Safety Monitoring when they are conducting clinical trials involving human participants as part of NIH-funded research. This description should outline the plan for oversight of participant safety and data integrity throughout the study.
What is preclinical screening?
Preclinical screening involves testing potential drugs or therapies in laboratory settings and animal models before they are tested in humans. It helps researchers assess the safety, efficacy, and potential side effects of the drug candidate before progressing to clinical trials in human subjects. This phase is crucial for identifying promising candidates and reducing the risk of harm to human participants during clinical trials.
Types of human resources required in clinical research?
Human resources that are required in clinical research include test subjects willing to undergo the clinical research and doctors, nurses, and technicians who actually apply the techniques.
How are scientific studies carried out to measure the effectiveness of pharmaceutically active chemicals?
Scientific studies to measure the effectiveness of pharmaceutically active chemicals typically involve rigorous clinical trials, which include phases of testing on cell cultures, animal models, and human subjects to assess safety, efficacy, and optimal dosages. For a deeper understanding of this process, you can visit this comprehensive guide.
Why clinical trials can't be done on human tissue samples only?
Clinical trials require studying the effects of a treatment in a living organism to understand its overall impact, including potential side effects and interactions with other bodily systems. Human tissue samples lack the complexity of a functioning organism, meaning that critical information about how a treatment interacts with the body as a whole would be missed.
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.
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.
How can you store tissue samples?
To store tissue samples for research, they are most of the time converted into FFPE blocks and stored in an airtight container, preferably in the refrigerator at 40 °C. It is also possible to store them as fresh frozen samples at -80 °C using dry ice or liquid nitrogen tanks.
