Clinical Trials01:16

Clinical Trials

10.2K
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: Overview

4.6K
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...

Statistical Software for Data Analysis and Clinical Trials

1.4K
Statistical software is pivotal in data analysis and clinical trials by providing tools to analyze data, draw conclusions, and make predictions. These software packages range from simple data management applications to complex analytical platforms, supporting various statistical tests, models, and simulation techniques. Their significance lies in their ability to handle vast amounts of data with precision and efficiency, enabling researchers to validate hypotheses, identify trends, and make...

Genome Annotation and Assembly03:36

Genome Annotation and Assembly

20.6K
The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.

Trial and Error and Algorithm01:12

Trial and Error and Algorithm

399
A problem-solving strategy is a plan of action used to find a solution. Different strategies have distinct action plans. Trial and error involves trying different solutions until one works. For instance, to fix a broken printer, you might check ink levels, ensure the paper tray isn't jammed, and verify the printer's connection to your laptop. This method can be time-consuming but is commonly used. Thomas Edison, for example, used trial and error to find a suitable filament for the light...

Area of Science:

  • Bioinformatics
  • Oncology
  • Clinical Trials

Background:

  • Precision oncology relies on matching patients to targeted therapies available in clinical trials.
  • A comprehensive and up-to-date clinical trial database is crucial for effective patient-trial matching.

Purpose of the Study:

  • To describe processes for establishing and maintaining a clinical trial database, specifically for genomically informed trials.
  • To present the Oncology Clinical Trial Annotation Engine (OCTANE) as a scalable informatics framework to support these processes.

Main Methods:

  • Developed OCTANE with three modules: data aggregation, annotation, and update.
  • Implemented OCTANE at a large cancer center to automate trial information retrieval, integration, and change monitoring.
  • The update module uses automated monitoring with alerts for manual intervention, achieving high accuracy compared to expert review.

Main Results:

  • Annotated 5,439 oncology clinical trials, including 4,438 genomically informed trials.
  • The database links trials to 1,453 drugs, 779 genes, and 252 cancer types.
  • Screened 4,220 patients for trial eligibility; the update module demonstrated 98.5% accuracy.

Conclusions:

  • OCTANE is a general informatics framework that facilitates automated patient-trial matching for routine precision cancer care.
  • The framework aids in establishing and maintaining comprehensive clinical trial databases.
  • Publicly available OCTANE components can benefit other precision oncology programs.
