How PPD supports customers across all phases
Extensive education & support ensure patient retention in CGT trials
Participation in a cell and gene therapy trial can place significant burdens on patients, from identifying trials to contending with a complicated trial experience that often requires five to 15 years of study follow-up. To best support patients and strengthen our understanding of their needs, we engage with patient advocacy groups and other stakeholders to bring patient voices into the trial development process as early as possible. This enables us to better recognize, appreciate and understand patient and caregiver challenges at each step of the patient journey.
Because of the high level of patient commitment and compliance required in CGT studies, we provide ongoing education and support to patients and caregivers to ensure that patients start and stay with the trial to the very end, including:
- Robust education and awareness campaigns to connect patients with trial opportunities
- “White glove” patient concierge service, which assigns a “personal assistant” to support each patient and caregiver
- Decentralized and digital study capabilities, including eConsent, home health and telemedicine
Together, these services ease the burden on patients to yield better engagement so that patients start and stay with CGT studies for their duration.
Ongoing development & training enable sites to execute complex CGT studies
CGT clinical trials are long, incredibly complex and full of uncertainties for even the most experienced sites. PPD’s solutions were built with these challenges in mind, to set up every trial site for success from beginning to end.
To ensure the successful execution of CGT studies, we have a growing global network of FACT1-, JACIE2– and EBMT3-accredited sites to identify the most appropriate location for your study and initiate startup. We also invest in guiding sites through necessary accreditations to participate in studies.
Once a site is initiated, we provide ongoing partnership to support the small details that make CGT trials successful, such as:
- Facilitating patient consent mock dry-runs
- Training staff to recognize immune responses
- Overseeing investigational product handling and sample tracking
- Providing comprehensive logistics support
By working together over many years, we have developed trusting relationships with the investigators and sites most engaged in this difficult, but rewarding, work. The quality of our relationships, in turn, translates into faster startup times, better collaboration and improved experiences for our customers.
Comprehensive training equips teams with CGT trial expertise
Our mature CGT solutions – and the opportunities to work on cutting-edge CGT programs while learning from eminent thought leaders – allow us to attract hard-to-find CGT talent. We are also committed to training, upskilling and reskilling our employees for future needs with our award-winning employee development programs. We develop specialized CGT expertise through our training programs and forums, including:
PPD’s exceptional learning culture and formal professional development not only support employees in their current roles, but also provide opportunities to expand their knowledge and skill sets. This positive culture increases employee engagement and retention while enhancing continuity in our customers’ research programs, ensuring stable relationships with skilled teams.
Cell & gene therapy institute (CGTI) helps sponsors conquer complexities
Cell and gene therapy development often involves the most intricate clinical value chain in modern medicine, demanding a CRO partner that appreciates both the technical and financial nuances of the field. As a newer therapeutic category, CGT clinical trials and approvals require diligence in collecting safety and efficacy data, and present unique logistical and scientific challenges.
PPD’s Cell and Gene Therapy Institute (CGTI) enables our customers to develop and execute successful trial strategies by leaning on PPD thought leaders and operations experts, a number of whom shaped the field of advanced therapy development from its origins. CGTI experts provide a wealth of experience that spans diverse technologies and delivery mechanisms, including cell, gene, gene-modified cell and advanced tissue technologies.
Benefits of CGTI for sponsors:
- Access to operational, functional, technical and therapeutic CGT expertise across all phases
- Better anticipation and mitigation of risks associated with these specialized trials
- Greater confidence and capabilities to advance your CGT asset through each stage in the process
How CGTI unites clinical & commercial perspectives to create compelling evidence narratives
PPD’S CGTI supports each CGT program with the people, processes and tools necessary to generate comprehensive data packages and identify novel pricing and reimbursement opportunities. CGTI drives medical and operational knowledge transfer, process and tool refinement and operational best practices by uniting our strategic and functional centers of excellence, including our:
By fostering collaboration between clinical and commercial leaders across the field, CGTI ensures each study is properly equipped to generate necessary data. The result? CGT clinical trials that run smoothly – and a cell and gene therapy asset that’s more likely to be approved by regulatory agencies, prescribed by physicians, wanted by patients and covered by payers at a price in line with the value it provides.
Specialized lab capabilities support the speed & complexity of CGT studies
CGT studies often require precise specialization, data and speed customized to the needs of each individual trial, making the right lab partner critical to the success of your study. PPD® Laboratory services apply decades of experience and combine high-quality scientific expertise with industry-leading technologies. Our bioanalytical lab services boast more than 20 years of experience, millions of samples analyzed and over 170 scientists and staff dedicated to cell and gene therapy. Our GMP lab has worked with over 60 cell and gene therapies across 15+ years.
PPD Laboratory services also offer a lab concierge program that takes seriously the security of the critical samples associated with CGT studies. This innovative program features a specialized project management team focused on sample management and logistics to ensure sample receipt, testing, initiation and coordination of data transfers.
Expert logistics management ensures chain of custody & chain of identity
Transporting, preparing and administering cell and gene therapy products is not just about securing resources and manpower. This important process requires expert navigation of multi-country transport, storage conditions, sensitive time frames and other critical details.
Because the stakes are high, our global clinical logistics efforts are supported by two dedicated roles. The logistics portfolio lead develops the logistics strategy for each CGT protocol and oversees our clinical logistics coordinators, who work collaboratively with sites, sponsors and shipment vendors to ensure timely and seamless transport at every stage.
With this approach, we know where the therapy is at all times, and the status of testing at multiple laboratories in different parts of the world – and we can facilitate the measuring and monitoring to ensure live biological therapies are meticulously tracked from end to end.
