Biostatistics
Obtain timely delivery of high-quality biostatistics with PPD’s comprehensive
statistical services. Our expert statisticians design, analyze and report clinical
studies across a broad range of therapeutic areas (including medical
device)
and are supported by robust processes and a global infrastructure.
Quality Deliverables, Global Standards
Located across four North American and three European sites, the biostatistics
team is experienced in all phases of global clinical trials, facilitating worldwide
consistency of standards and quality. Our working practices include:
- Programming based on written specifications
- Independent quality validation of formal deliverables to verify accuracy
and audit readiness
- Senior statistical review of all deliverables, from protocol writing through
regulatory submissions
Comprehensive Analysis Plans
Concise, accurate reporting of study results begins with development of clear
protocols and user-friendly case report forms. From there, our statisticians
interact with sponsor scientists to develop a comprehensive statistical analysis
plan, including:
- Overview of study objectives, description of study population, sample size
rationale and statistical power
- Conventions and definitions for summary and analysis of demographic, baseline,
efficacy and safety data
- Detailed description of statistical methodology
- Shells of all planned tables, listings and figures
Complete, Concise Reporting
Based on a well-developed plan, statistical analysis implementation provides
sponsors with timely, high-quality deliverables. We ensure complete, concise
reporting through:
- Analysis strategies that are ICH compliant
- Production of tables, listings and figures, audit-ready at delivery
- Development of comprehensive methods reports describing planned and exploratory
analyses
- Collaboration with medical writers and clinical scientists to ensure appropriate
interpretation of quantitative results
- Support for manuscripts and abstracts
Client-Focused Teams
Our teams are focused on sponsor needs, timelines and client-specific analysis
standards. We have the flexibility to support aggressive timelines, project priorities
and various business models and work closely with the client, facilitating collaborative,
proactive communication.
Expert Statistical Scientists
PPD’s global biostatistics team has a broad range of therapeutic experience,
and statisticians hold advanced degrees. All of our statisticians and statistical
programmers receive ongoing, intensive training that incorporates:
- Industry information such as 21 CFR Part 11
- GCP and ICH standards
- SAS
software programming skills
- Statistical methodology
Team members are also current with industry standards and market trends, such
as Clinical Data Interchange Standards Consortium (CDISC) models.
