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...
Study Designs in Epidemiology01:20

Study Designs in Epidemiology

Epidemiological study designs are fundamental tools for investigating the distribution, determinants, and control of health conditions in populations. They help researchers understand the relationships between exposures and outcomes, and they broadly fall into two categories: "observational" and "experimental" studies.
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and case-control studies.

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

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, controlled...
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...
Bioequivalence studies: Biowaivers01:13

Bioequivalence studies: Biowaivers

In certain scenarios, in vitro dissolution tests can replace in vivo bioequivalence studies. This is particularly true when a drug product, though available in varying strengths, maintains proportional similarity in its active and inactive ingredients. In such cases, the need for in vivo bioequivalence studies for lower strength variants may be waived, provided dissolution tests and in vivo studies on the highest strength yield satisfactory results.Bioequivalence can be indicated through...
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,...

Summary

Research governance approval for multicentre studies in the UK experiences significant delays, averaging 43 working days. This impacts the timely initiation of ethically approved research, highlighting a need for process improvements.

Area of Science:

  • Medical Research
  • Health Services Research
  • Clinical Trials Management

Background:

  • Research governance approval is a critical step for initiating studies.
  • Delays in this process can significantly impact research timelines and outcomes.
  • Understanding the extent and reasons for these delays is essential for improving research infrastructure.

Purpose of the Study:

  • To quantify the delay in obtaining research governance approval for a non-interventional, multicentre study.
  • To identify factors contributing to these delays within the UK healthcare system.

Main Methods:

  • Prospective recording of time from application to approval for an observational study of childhood stroke.
  • Data collected from 92 acute NHS Trusts in the United Kingdom.
  • Median delay in working days was the primary outcome measure.

Main Results:

  • The median delay for research governance approval was 43 working days (IQR: 27-62).
  • For 44 trusts, delays exceeding 43 working days were inexplicable in 70% (30 trusts).
  • A wide range of delays was observed (0-147 working days).

Conclusions:

  • Significant variability exists in research and development processes across NHS Trusts.
  • These variations lead to substantial delays in commencing ethically approved studies.
  • Improvements in the research approval system are necessary to facilitate research initiation.
