Clinical Trials01:16

Clinical Trials

Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.
There are four phases in a clinical trial. A phase one...
Clinical Trials: Overview01:11

Clinical Trials: Overview

Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...
Bioavailability Study Design: Healthy Subjects Versus Patients01:15

Bioavailability Study Design: Healthy Subjects Versus Patients

Bioavailability studies are essential for evaluating a drug's therapeutic efficacy and understanding its absorption patterns under various physiological conditions. Conducting such studies on target patient populations provides more relevant data by simulating real-world disease states. However, practical challenges often necessitate the use of young, healthy adult volunteers as study subjects.Patients may exhibit altered drug absorption patterns due to the effects of the disease itself,...
Preclinical Development: Overview01:28

Preclinical Development: Overview

Preclinical development consists of a series of tests that ensure the safety and efficacy of a new therapeutic compound before it is tested in humans. There are four main phases to this process. First, safety pharmacology tests are conducted to ensure the drug does not produce any acutely harmful effects. These tests examine parameters such as bronchoconstriction, cardiac dysrhythmias, blood pressure changes, and ataxia. Next, preliminary toxicological testing is performed to determine the...
Cognitive Development During Adolescence01:18

Cognitive Development During Adolescence

During adolescence, individuals experience significant cognitive development that enhances their understanding of others' emotions and thoughts, known as cognitive empathy. This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the recognition that people have...
Drug Administration and Therapy Phases: Overview01:26

Drug Administration and Therapy Phases: Overview

Drugs, the chemical agents used in diagnosing, treating, or preventing diseases, undergo a four-phase process of development: pharmaceutic, pharmacokinetics, pharmacodynamics, and therapeutic.
The pharmaceutical phase focuses on leveraging the physicochemical properties of the drug to design and manufacture an effective product. Variants include orally administered tablets or capsules, topical creams or ointments, and parenteral-delivery solutions or emulsions.
The pharmacokinetic phase...

Area of Science:

  • Pharmacology and Drug Development
  • Clinical Trial Design
  • Adolescent Medicine

Background:

  • Drug development is a complex, expensive, and time-consuming process.
  • Clinical trials are crucial for assessing drug dosing, safety, and efficacy in diverse populations.
  • Adolescents are frequently underrepresented in clinical trials, despite broad post-approval drug usage.

Purpose of the Study:

  • To explore the consideration of adolescents in drug development.
  • To examine the influence of psychosocial, biological, ethical, and regulatory factors on adolescent recruitment and participation in clinical studies.
  • To highlight challenges in including adolescents in the drug licensing process.

  • This is a commentary, not an empirical study.
  • It involves a review and discussion of existing literature and issues related to adolescent participation in clinical trials.
  • Focuses on inherent factors influencing recruitment and engagement.

Main Results:

  • Adolescents are commonly overlooked in drug development pipelines.
  • Psychosocial, biological, ethical, and regulatory issues significantly impact adolescent involvement in clinical studies.
  • Current practices may not adequately address the unique needs and circumstances of adolescent populations.

Conclusions:

  • There is a need to improve the inclusion of adolescents in clinical trials.
  • Addressing the identified factors is essential for equitable drug development.
  • Enhanced strategies are required to ensure adolescent representation for safe and effective drug licensing.
