Clinical Trials: Overview01:11

Clinical Trials: Overview

4.0K
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...

Clinical Trials

9.9K
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...

Preclinical Development: Overview01:28

Preclinical Development: Overview

5.3K
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...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

214
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,...

Radiological Investigation I: X-ray and CT

610
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

Study Designs in Epidemiology01:20

Study Designs in Epidemiology

560
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...

Area of Science:

  • Clinical Diagnostics
  • Public Health Preparedness
  • Infectious Disease Research

Background:

  • The COVID-19 pandemic necessitated rapid development of diagnostic tests.
  • Existing diagnostic development timelines are often lengthy and costly.
  • The National Institutes of Health (NIH) established the Rapid Acceleration of Diagnostics (RADx) Tech initiative to expedite this process.

Purpose of the Study:

  • To outline the structure and function of the Clinical Studies Core (CSC) within the RADx Tech initiative.
  • To detail the CSC's role in supporting the development and commercialization of SARS-CoV-2 point-of-care tests.
  • To highlight the CSC's contribution to diverse population and setting-based device studies.

  • Development of a robust clinical study infrastructure in under several months.
  • Implementation of a master protocol, digital study platform, and data management system.
  • Establishment of a single Institutional Review Board (IRB) and multi-site partnerships for efficient study execution.

Main Results:

  • Successful development of infrastructure enabling rapid SARS-CoV-2 device studies.
  • Data generated are supporting Emergency Use Authorization applications for novel diagnostic tests.
  • Demonstrated reduction in typical medical device development time and cost.

Conclusions:

  • The CSC effectively accelerated the development and deployment of critical diagnostic tools.
  • Academic and NIH partnerships proved vital for addressing urgent public health needs during a pandemic.
