When I go in, I go all in and I'm passionate about what I do. I feel like at the end of the day, what I am doing is impacting somebody.

My name's Hena Sleem and I am an executive director of Clinical Operations at Parexel.

FSP stands for functional service provider. So as an FSP provider, we're able to quickly deploy resources with required expertise, experience, geographic diversity, going into regions where we have incredible pools of talent, access to the best patient populations as well.

Parexel's time to fill metric is best in class. Our talent acquisition teams are already hiring in key locations for key roles before there's actually open positions, and are recruiters from our talent acquisition team are geographically aligned to sponsors so that way they understand the sponsor's cultures, the needs that the client has in order to be able to be successful in the role.

An area that FSP often supports right now is the deployment of site relationship partners. This allows sponsors to further strengthen the engagement with sites. The core tenet behind this role is to focus on the investigator patient's needs and shifting them to the center of the clinical trial. At Parexel, we're very proud that our FSP partnerships are delivering with heart by embedding talent who have the primary focus of advocating and connecting the patient voice into the broader and complex clinical development journey.

Clinical operations

From study start-up to quality assurance and risk management, our clinical operations personnel (CRAs, study managers, start-up specialists, operations managers, and data managers)  provide flexible and customized solutions to meet your specific needs while ensuring high-quality clinical trial execution.

You'll benefit from flexible resource allocation, improved cost-efficiency, enhanced quality, and accelerated timelines. We deliver tailored solutions that are aligned with your unique needs.

Our clinical operations personnel can complement your internal expertise or handle all operational aspects of your studies.

Data management

Our data operations experts efficiently and accurately manage clinical trial data throughout its lifecycle. This includes data collection, processing, validation, analysis, and reporting. The team ensures that data is captured in a standardized and reliable manner, adhering to regulatory requirements and industry best practices.

The data operations team collaborates closely with sponsors, clinical operations teams, and other stakeholders to develop data management plans, establish data standards, and implement data capture strategies. They are responsible for setting up electronic data capture systems, developing data validation checks, and cleaning the data to ensure its quality and integrity.

Medical affairs

Our medical affairs professionals (medical science liaisons, clinical trial liaisons, and clinical nurse educators) work closely with you to establish and implement strategic plans for your products. This involves providing scientific and medical expertise, evidence generation, and strategic guidance to drive product development, support regulatory submissions, and facilitate patient access.

Additionally, they actively engage with key opinion leaders, healthcare professionals, regulatory authorities, and patient advocacy groups to foster relationships and garner valuable insights.

Medical writing

Our medical writing team works closely with you to create high-quality, well-structured, and scientifically accurate documents that support your clinical development and regulatory strategies.

Our team includes roles such as associate medical writers, senior medical writers, document quality reviewer, principal document quality reviewer, document specialist, lead document specialist, and medical writing support coordinator. 

This collective team handles everything from document writing and preparation for product development, approval, and commercialization to authoring, medical writing project management, trial disclosure, and publishing.


Our global regulatory colleagues (including regulatory affairs managers, compliance experts and project managers) provide expertise across a range of outsourced regulatory solutions, including regulatory dossier compilation, publishing and dispatch, clinical trial applications, centralized CMC and labelling and post-approval submissions and lifecycle management. We also partner with clients on project-based deliverables including regulatory strategy, market authorization submissions, M&A license transfers and RIM – data entry, data cleansing, data migration. 

We work with clients on asset-based outsourcing, often for mature products or low-risk portfolios or on a functional basis for activities like CMC, labeling or publishing. Services are delivered by a unitized (deliverable) model, or an FSP (dedicated FTE) model.

By outsourcing and consolidating non-core regulatory activities, our experts can ensure your regulatory team focuses on core business activities and your development pipeline.


Our pharmacovigilance function serves to ensure the safety and well-being of patients participating in clinical trials. Our PV team is responsible for the efficient collection, evaluation, and reporting of adverse events and other safety-related information to the relevant regulatory authorities. We comply with global regulatory guidelines and industry standards to ensure the highest level of patient protection.

Through close collaboration with our FSP partners, we establish and maintain robust safety management plans, develop standard operating procedures, and conduct thorough safety trainings.

Translational medicine

Our translational medicine group -- comprised of scientific directors, biomarker sample management specialists, biomarker sample operations associates, and precision medicine associate directors -- conceives and implements data-driven, target therapy development strategies to deliver novel therapies that treat patients based on their unique genomic and biomarker characteristics. Our genomic medicine scientists apply expertise, innovation and state-of-the-art methodologies in the strategic and operational implementation of genomics and biomarker services to help clients:

  • Better understand the genetic/genomic basis for the disease, drug, target, and pathway
  • Differentiate drugs from competitor medicines in development or on the market
  • Stratify drug responders/non-responders and enrich clinical trial design
  • Develop biomarker and companion diagnostics strategies
  • Inform the benefit-risk profile of personalized medicine



FSP stands for Functional Service Provider in clinical research. It is a model in which a company outsources specific functional activities or services to a third-party service provider. FSPs work closely with the sponsor organization to provide specialized expertise, resources, and operational support in areas such as data management, biostatistics, clinical monitoring, drug safety, and regulatory affairs. By engaging an FSP, sponsors can enhance efficiency, flexibility, and cost-effectiveness in delivering clinical trials.

FSO stands for Functional Service Outsourcing, while FSP stands for Functional Service Provider. Both FSO and FSP are models commonly used in the pharmaceutical and clinical research industry to support specific functions or services required in a clinical trial.

FSO refers to the outsourcing of specific functions or activities to an external service provider. In an FSO model, the service provider takes ownership of the entire function and provides all the necessary resources, infrastructure, and expertise to perform the activities. For example, a company may outsource its clinical data management function to an FSO provider.

On the other hand, FSP refers to the engagement of an external service provider to provide specific expertise or resources while working in collaboration with the internal team. In an FSP model, the service provider works as an extension of the internal team, focusing on providing the required expertise or resources for a specific function. For example, a company may engage an FSP provider to provide biostatistics support for a particular clinical trial.
