Clinical Data Standardization

We are Subject Matter Experts in clinical data standards with a focus on helping clients leverage the CDISC SDTM and ADaM for both their internal practices/processes and regulatory submission. We leverage our extensive experience in clinical data standardization and integration services/solutions to help our clients successfully navigate the challenging waters of the clinical data life-cycle, from collection to eSubmission.

Our goal is to bring a unique value-added combination of technology and data standards together in an efficient way from both a time and resource/cost perspective to improve the flow of data from collection to eSubmission. We employ scalable best practices and tools for standardization of data from the collection source, statistical programming and development of the eSubmission deliverables.

Medical Writing Unit

At Symbiance, our focus is our client. Our breadth of expertise, honed by over twenty years in the industry, helps us understand that clear, succinct reporting is the difference between a successful, fast-paced study and one stuck in the bogs. What you can expect from Symbiance is crisp reports that fit your submissions package and provide transparency on the progress of your clinical study. Customized writing and reporting is how we deliver results that count.

Symbiance's medical writers work collaboratively with CDM experts and biostatisticians to produce clinical writing deliverables that reflect the clinical experience and integrity of our firm. Our writers also have access to cross-functional internal teams with whom they collaborate on therapeutic areas so that the end result is a holistic, customized document. We also team up with medical writers that are trained in emerging biotechnological specialties and work with academics to prepare reports that enable secure submissions and more effective drug development.

Quality Gate Keeping Service

Not only can Symbiance provide the core services of data management and biostatistics, but we can also provide niche services to improve the quality, consistency and integrity of your clinical trial data, which we refer to as 'quality gatekeeping'.

One example of this is SDTM QC, which we are performing for few clients. We have dedicated team of SDTM experts for each of these customers and we have implemented programs that detect discrepancies between the SDTM delivery datasets/metadata against the sponsor's standards documentation. These discrepancies are then sent to the sponsor to be addressed and fixed in subsequent SDTM deliveries. This is a continuous process throughout the course of the study until the final SDTM delivery of the locked database. Another example is external data SDTM reconciliation, in which we compare the raw external data collection (i.e. labs, ecg, etc.) against the appropriate SDTM domain to ensure reconciliation is accurate at the SDTM level. Any discrepancy is sent to the sponsor/CRO for fixing in subsequent deliveries and is repeated until all discrepancies are resolved. Another example of a niche service is UAT testing of EDC systems. Being a small CRO allows us the flexibility to be trained and use any EDC of the sponsors choosing. Once trained, we can perform the appropriate testing and provide our UAT findings to the EDC development team for implementation. This approach allows issues to be addressed and fixed before the EDC system is deployed in a production environment. These are just a few examples of niche services we can provide to improve your clinical data quality. We are the extended team of the sponsor for data quality.
