In recent years, leaders in the pharmaceutical industry have relied on data science to guide their decision making around vital drug development objectives. Data science experts have multiple layers of responsibilities that include exploring and evaluating data; model development and validation; examining research patterns and generating data insights. And, after all of that, they have to effectively communicate the results in a meaningful way that impacts decisions. Requiring key expertise, functional service providers (FSPs) can play a critical role in guiding and advancing these responsibilities.
In clinical research, sponsors and some service partners typically use legacy systems like SAS to analyze data, input results and generate insights from it. It’s a conventional method to data analysis. However, being a paid software, SAS does not allow for open-source algorithms. In the last decade, it has gradually become apparent to industry stakeholders that taking advantage of historical data has benefits worthy of consideration for sponsors.
In aiming to best leverage data insights and ensure enhanced decision making and cost-effective process improvements, it is critical to know what tools experts in statistics, analytics and visualization may find critical for success, which a functional service provider (FSP) manager can help identify per the project needs. Statisticians have been migrating to is open source R and Python programming languages as a supplement to SAS software.
R and Python are gaining relevance as part of the drug discovery and development process. As open-source programming environments with a robust and committed online communities, R and Python have become a powerful set of tools for statisticians and are used extensively within drug development—from molecule to market.
By integrating the data and applying useful algorithms, sponsors can benefit from the extensive data insights needed to make clinical trials more agile and adaptable, ultimately increasing productivity and efficiency to improve success rates. It is important to heighten these efficiencies using the sophisticated tech-enabled solutions and best in analytics platforms to tweak, analyze and leverage large amount of data.
Depending on the individual project needs, experienced FSP statisticians will ask the question, “What is best to use—R or Python?”
In data science, both R and Python are freely available and popular open source programming languages. But, there are key differences that those working in data analysis should consider. In a nutshell, Python can be considered superior as a programming tool for text analytics and mining of big data. Consider, for example, actigraphy data collection: This can easily generate huge volumes of data that need to be processed, particularly if one is using a functional statistics approach to the analysis. On the other hand, R provides more value for statistical analysis and visual data mining needs.
Integrating FSP experts who hold the right experience and technical training to know these programming languages well and understand how to maximize the benefits of each is extremely useful when working to secure key data points that will guide the decision-making process for sponsors and study teams.
Statisticians will need to be able to determine which language to use based on the problem under study or key objectives of the analysis at hand. For example, if one is needing statistical analysis rather than text analysis, R programming language is ideal. Alternatively, if one needs to develop a web application or prefers to use general purpose programming language, Python is the preferred choice, given it supports varying data formats. Though for web development one might also want to consider Shiny apps, which allow for a quick and easy statistical application delivered via the browser. The table below (fig1) outlines a simplified set of criteria a biostatistician could use to determine which software fits the problem at hand.
