What Is The FSP Model & How Does It Work?
FSPs offer sponsors precision, scalability, and expertise for clinical research by providing targeted support in key areas.
What Is The FSP Model?
FSPs manage specific trial functions, such as clinical monitoring, data management, biostatistics, pharmacovigilance, or regulatory affairs. This model provides scalability, operational continuity, and increased oversight and is especially beneficial to sponsors juggling multiple trials or therapeutic areas.
Key Differences From Full-Service CROs
FSPs and CROs both provide critical services for clinical trials, but they differ in how work is structured, delivered, and managed.
CROs typically operate under a full-service model, providing integrated services across the entire clinical trial life cycle. Although the sponsor maintains control over the trials’ strategy and high-level decision-making, the CRO handles day-to-day operations.
FSPs, however, specialize in certain functional roles or departments, such as clinical monitoring, data management, or biostatistics. Sponsors engaging FSPs retain operational oversight of the trial, and FSP staff usually work with the sponsor’s systems, SOPs, and teams. FSPs also differ from CROs in the following key areas:
- Governance and oversight: Typically, sponsors oversee FSP operations, while full-service CROs manage cross-functional coordination internally.
- Contract structure: Sponsors engaging FSPs often use FTE or unit-based contract models that are tied to specific deliverables or roles rather than study-level contracts preferred by CROs.
- Resource continuity: FSP models can maintain resources across multiple trials or programs, reducing onboarding time and preserving institutional knowledge.
- Customization and control: FSP engagements can be customized to fit sponsor systems, workflows, and organizational culture. CROs, however, generally use their own processes and platforms.
According to industry expert and consultant Samir Shah, FSPs are overtaking CROs in the clinical trial marketplace. Shah explains that although small companies and startups may require the end-to-end services that CROs offer, Big Pharma increasingly wants to partner with best-in-class providers for specific clinical trial functions.
Structure Of FSP Relationships
FSP partnerships are commonly structured in one of three ways, depending on the trial's complexity and duration and the sponsor's need for flexibility vs. predictability.
- Service agreements define deliverables by function or project.
- Unit-based pricing is based on measurable outputs like data query resolutions or monitoring visits.
- FTE models contract dedicated professionals for a set period of hours or days, offering consistent support over time.
Integration With Sponsor Teams
Ideally, sponsors should integrate external FSP talent with their internal team for seamless collaboration. Inviting FSP staff to internal meetings, training them on sponsor systems, and requiring them to follow the sponsor's SOPs all are designed to facilitate an efficient workflow and preserve trial continuity.
Successful integration also requires transparent onboarding processes, role definition, and consistent communication between sponsor and provider. These partnerships thrive when sponsors view the FSP as an extension of internal operations rather than a separate vendor.
Dedicated Vs. Shared Resources
FSP models often use either dedicated or shared resources. Dedicated resources focus exclusively on the sponsor’s projects, becoming deeply familiar with internal processes, priorities, and team dynamics. This model works well for long-term partnerships or high-volume trials.
However, an FSP may adopt a shared resources model and support multiple sponsors or therapeutic areas. This arrangement can be less costly, which is advantageous for smaller sponsors or limited-scope engagements. Additionally, therapeutic complexity and operational priorities are factors to consider when weighing dedicated vs. shared resources.
Role Of Technology & Data Systems
FSPs rely on eClinical platforms to align with sponsors on trial execution. For example, electronic data capture (EDC), clinical trial management systems (CTMS) provide real-time visibility into the trial’s progress and performance.
Depending on the partnership arrangement, FSPs may use systems owned by the sponsors or provide sponsors with access to their platforms. Standardized data models, dashboards, and communication tools further align workflows and ensure compliance across distributed teams.
Examples Of FSP Service
FSPs can support many clinical trial functions, and these services can be tailored to the sponsor and study’s particular needs. Sponsors also decide whether to engage the FSP in one study or across multiple studies and programs.
Providing Clinical Monitoring
FSP clinical monitoring teams oversee site performance, ensure protocol adherence, and verify source data. They commonly work with the sponsor's systems and processes for continuous oversight and quick issue resolution.
This role also maintains data integrity and regulatory compliance across site locations, enabling sponsors to scale monitoring resources based on study complexity and enrollment trends.
Streamlining Data Management
FSPs also offer data management, including data capture, processing, and analysis. They can provide database setup, CRF design, query management, and data cleaning while adhering to strict quality standards. Specialized personnel and validated systems allow FSPs to streamline the data lifecycle, minimize delays, and support faster database lock for efficient trial progression.
Developing Biostatistics
Sponsors may also use FSPs for statistical expertise in study design, analysis, and reporting. FSP statisticians work with sponsor teams to create analysis plans, perform interim and final analyses, and generate regulatory submission outputs. This support enhances methodological rigor and clinical-finding credibility to help sponsors meet evolving regulatory expectations.
Key Benefits Of The FSP Approach
FSPs offer many operational and strategic advantages across the development lifecycle, including cost efficiencies and accelerated timelines.
Flexibility & Scalability
FSPs can rapidly scale functional capabilities up or down according to the trial's evolving needs, portfolio adjustments, or pipeline shifts. Regardless of the study’s size or distribution, FSPs help sponsors tailor resource levels appropriately, safeguarding business continuity and ensuring efficient resource planning in unpredictable development environments.
Cost Control & Resource Efficiency
The FSP model’s targeted approach to trial support allows sponsors to reduce personnel overhead and avoid engaging full-service providers when they only need limited support. In particular, unit-based pricing and FTE systems engender transparent budgeting and reliable financial planning.
FSPs also provide cost savings by improving productivity, increasing labor efficiency, and optimizing resource utilization. These benefits are especially critical for small to midsized biotech firms with constricted budgets.
Continuity, Quality, & Compliance
Commonly, FSP partnerships span multiple studies and therapeutic areas, providing continuity in personnel, process, and institutional knowledge. This continuity improves deliverables' quality and reproducibility while ensuring compliance. An experienced FSP can align with the sponsor's SOPs and applicable regulatory requirements to prepare for inspections and meet global GCP standards.
