Preclinical Development: Overview01:28

Preclinical Development: Overview

4.3K
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...

Clinical Trials: Overview

2.9K
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...

Drug Administration and Therapy Phases: Overview

416
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...

Clinical Trials

6.6K
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...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

124
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Nursing Ethical Principles II01:27

Nursing Ethical Principles II

934
Ethical principles are essential in guiding nurses to fulfill their responsibilities, focusing on the quality of nursing care and decision-making. These principles, including autonomy, beneficence, non-maleficence, justice, and fidelity, shape the ethical framework within healthcare settings.
Consider the following scenario, which illustrates how these principles are applied in the care of Mr. John, a fifty-year-old teacher diagnosed with metastatic liver cancer.
Initially, Mr. John's...

Summary

This study applies quality principles to Phase I model-based dose escalation designs. It interprets loss functions as ethical assumptions, guiding better clinical trial design for patient safety.

Area of Science:

  • Clinical Trial Design
  • Biostatistics
  • Quality Engineering

Background:

  • Phase I clinical trials require robust dose escalation designs.
  • Ethical considerations are paramount in determining patient dosage.
  • Model-based designs offer a structured approach to dose escalation.

Purpose of the Study:

  • To discuss quality principles for Phase I model-based dose escalation.
  • To interpret loss functions as quantified ethical assumptions in trial design.
  • To provide guidance for developing high-quality clinical trial designs.

Main Methods:

  • Applying quality philosophy principles (Taguchi, Deming) to dose escalation.
  • Interpreting loss functions within the context of ethical decision-making.
Keywords:
