"Clinical trials are prospective biomedical or behavioral research studies on human participants designed to answer specific questions about biomedical or behavioral interventions..."
Clinical trials refer to studies in humans that evaluate the safety and effectiveness of new drugs and other treatments.
Introduction to Clinical Trials: A brief overview of clinical trials and their significance in drug development and healthcare.
Preclinical Drug Development: Understanding how drugs are developed in preclinical stages, including animal studies and toxicity testing.
Phase I Clinical Trials: An introduction to the first phase of clinical trials, determining drug safety and dosage range in a small group of healthy humans.
Phase II Clinical Trials: A discussion of the second phase of clinical trials, involving a larger group of patients to determine drug effectiveness and side effects.
Phase III Clinical Trials: The third and final phase of clinical trials, which often involves a much larger group of patients and is aimed at proving the efficacy and safety of the drug.
Regulatory Requirements: An overview of the regulatory requirements needed for clinical trials, including approval by regulatory bodies, informed consent, and ethical considerations.
Clinical Trial Design: Understanding the different types of clinical trial designs, such as randomized controlled trials, crossover trials, and open-label trials.
Randomization and Blinding: Guidelines for randomization, blinding, and placebo control in clinical trials.
Data Collection and Analysis: A discussion of the processes used to collect and analyze data in clinical trials.
Clinical Trial Endpoints: Understanding the different types of endpoints used in clinical trials, such as clinical and surrogate endpoints.
Adverse Events and Safety Monitoring: Guidelines for monitoring and reporting adverse events and safety in clinical trials.
Data Safety Monitoring Boards: An overview of the role of Data Safety Monitoring Boards (DSMBs) in clinical trials, including their composition and responsibilities.
Statistical Analysis and Interim Analysis: Understanding the importance of statistical analysis and interim analysis in clinical trials.
Clinical Trial Management: An introduction to the role of Clinical Trial Managers (CTMs) in the planning and management of clinical trials.
Patient Recruitment and Retention: Strategies for patient recruitment, retention, and engagement in clinical trials.
Investigational Drugs: Understanding the regulation and use of investigational drugs in clinical trials.
Good Clinical Practice (GCP): Guidelines for conducting clinical trials according to Good Clinical Practice (GCP) standards.
Clinical Trial Budgeting and Contracting: A discussion of the budgeting and contracting processes involved in clinical trials.
Intellectual Property and Patents: Understanding the role of intellectual property and patents in drug development and clinical trials.
Ethical Considerations: A discussion of the ethical considerations involved in conducting clinical trials, including vulnerable populations, informed consent, and conflicts of interest.
Phase 1 clinical trial: This is the first time a new drug, device, or treatment is tested on a small group of healthy volunteers to determine its safety, dosage range, side effects, and other basic information.
Phase 2 clinical trial: This type of trial is conducted to determine the effectiveness of a new drug, device or treatment on a larger group of patients with the condition it is intended for. This trial helps to determine the optimal dosage and how safe the intervention is.
Phase 3 clinical trial: This type of trial involves testing the new drug, device, or treatment on a larger group of patients to evaluate its effectiveness, safety, and possible side effects when compared to the current treatment options.
Phase 4 clinical trial: After a drug has been approved by the FDA, phase 4 clinical trials are conducted to monitor its long-term effectiveness and safety post-approval.
Parallel group trial: It is when subjects are allocated to different groups and they receive different treatments.
Randomized controlled trial (RCT): This is when participants are randomly assigned to the different groups to avoid selection bias. This is considered the highest level of evidence.
Non-randomized controlled trial: This trial doesn’t use randomization on how participants are assigned to groups, but there will still be a control group.
Double-blind trial: Neither the participants nor the researchers know who is in the experimental group or control group.
Single-blind trial: Only the participants are unaware of which group they belong to, but the investigators know.
Crossover trial: Participants receive a sequence of two or more treatments, the order of which is decided randomly.
Adaptive design trial: This design allows for modifications in the trial design based on early results.
Time-series trial: Participants are monitored over a certain period of time before, during, and after intervention.
Factorial trial: Examines the effects of two or more interventions at the same time, rather than just one.
Cluster-randomized trial: The intervention is assigned to groups, rather than individuals.
Bioequivalence trial: Compares two formulations of medication to see if they are equivalent in efficacy and safety.
Dose-escalation trial: Begins with a lower dosage and gradually increases to determine the maximum tolerated dose.
Pharmacokinetics/pharmacodynamics (PK/PD) trial: Examines the effect of a drug and how it is metabolized and eliminated.
Pilot trial: A small-scale trial to test feasibility and acceptability of a proposed intervention.
Exploratory trial: Conducted to generate hypotheses and assess the feasibility of a future trial.
Mechanistic trial: Focused on understanding the underlying biological mechanisms of a disease, and how a particular drug or device interacts with these mechanisms.
"...including new treatments (such as novel vaccines, drugs, dietary choices, dietary supplements, and medical devices) and known interventions that warrant further study and comparison."
"Clinical trials generate data on dosage, safety and efficacy."
"...they have received health authority/ethics committee approval in the country where approval of the therapy is sought. These authorities are responsible for vetting the risk/benefit ratio of the trial..."
"...their approval does not mean the therapy is 'safe' or effective, only that the trial may be conducted."
"Depending on product type and development stage, investigators initially enroll volunteers or patients into small pilot studies..."
"...and subsequently conduct progressively larger scale comparative studies."
"Clinical trials can vary in size and cost..."
"The sponsor may be a governmental organization or a pharmaceutical, biotechnology or medical-device company."
"Certain functions necessary to the trial, such as monitoring and lab work, may be managed by an outsourced partner, such as a contract research organization or a central laboratory."
"...they take 11–14 years to complete."
"Only 10 percent of all drugs started in human clinical trials become approved drugs."
"Clinical study design aims to ensure the scientific validity and reproducibility of the results."
"...their approval does not mean the therapy is 'safe' or effective, only that the trial may be conducted."
"Clinical trials can vary in size and cost..."
"Clinical trials can involve a single research center or multiple centers, in one country or in multiple countries."
"...new treatments (such as novel vaccines, drugs, dietary choices, dietary supplements, and medical devices) and known interventions that warrant further study and comparison."
"These authorities are responsible for vetting the risk/benefit ratio of the trial..."
