    Optimizing Current and Future Biotech Research Results

    4 ways clinical operations professionals can optimize clinical study outcomes

    The quality of a biospecimen can influence the outcome of pharmaceutical and biologic studies long before the actual research begins: Non-standardized collection materials, improper processing procedures, and inadequate storage conditions enter the biospecimen life cycle in the form of pre-analytical variability, ultimately impacting the outcome of your study.

    Downstream stakeholders, most often researchers and data analysts, have limited visibility of the biospecimen life cycle. They assume proper material, technique and protocol adherence has been accounted for. Typically this doesn’t become obvious until late in the study, when timelines and budgets are under increased scrutiny and redoing a study isn’t an option.

    Sponsors have begun to take notice of this common oversight, and are leaning on the expertise of clinical operations specialists to standardize and integrate study logistics and biospecimen availability and quality. Clinical Ops teams are challenged to deliver upon more precise protocols & studies, within tighter budgets, and an increasingly competitive clinical environment.

    Setting your organization and study apart from other Sponsors, through the use of site-friendly clinical materials and procedures, will ensure delivery on the challenges of today and build a foundation for future studies.

    Following are 4 best practices to weave the likelihood of success into your clinical program from kit to collection:

    1) Understanding the Process Flow at Investigator Sites

    Lagging enrollment isn’t always the result of low patient targets. In many programs, it’s the undesirable outcome of study designs that didn’t take the flow of routine patient care at the site into consideration. Each practice (investigative site) is unique, and so are the roles and personalities within them.

    Get to know the flow — beginning with a site interview — to find path of successful enrollment/specimen collection. Use the following key points to frame your discussion:

    • Consent: Who will obtain it and where?
    • Collection: Where will it be collected? (in the exam room, draw station, elsewhere?)
    • Processing: Does the specimen need to be transported elsewhere for processing? (on-site lab, outsourced?)
    • Short term – Long term Storage: Where will the biospecimen be held, and how will it be stored until it is shipped to the laboratory?

    Involving each site’s key role players in this process — the nurses, administrative, and laboratory staff — ensures that the “intangible” influencers of your enrollment success are accounted for in the study design.

    Understanding the flow of patient care in the clinical setting (including staff roles and available resources), and building this into the design of study procedures and supplies will increase the likelihood that your study is the one to which coordinators prioritize.

    2) Utilize Site-Specific Study Kits for More Flexible Collection

    In today’s clinical setting, there are a number of role players responsible for providing efficient, quality patient care — making it unlikely that any single person will perform every step in the process of your study, from enrollment and data capture to specimen collection and  management.

    For this reason, it is poor practice to create one-size-fits-all study kits that travel with the patient throughout their visit. Managing the enrollment and collection process in this way introduces unnecessary risks that can potentially impact the quality of biospecimens.

    A better way to manage the process is to create site-specific study kits that balance the process of care with specific study procedures to ensure efficient and accurate compliance with the study protocol.

    For example, many sites perform phlebotomy in the clinic, while centrifugation, processing, and aliquoting occurs in a separate suite or building. For these sites, the optimal study design would incorporate two process-specific study kits linked together with a common identifier.

    An example of this type of solution is;

    1. Collection Kit; for consent, enrollment, and collection
    2. Processing Kit; for separating, aliquoting, and storing the specimens

    Utilizing site-specific study kits that align with patient care and staff workflow enables efficient utilization of resources and precise handling of biospecimens.


    3) Standardize Study Supplies

    Slight variations in materials and supplies can affect the recovery and performance of samples in subsequent clinical or molecular analysis. Unfortunately, the person who is impacted the most by this — the researcher — is typically not involved in selecting the collection or processing materials.

    Involving the end user in the qualification, selection, and standardization of supplies can help Clinical Operations professionals avoid downstream performance and research variability.

    A collection tube is a great example of how a simple component can result in unexpected research results. Here is a real-world example:

    A study was designed to correlate unique biomarker levels in plasma to a known disease state. The project manager for the research team contacted clinical supply to order collection kits containing plasma tubes with K3 EDTA anticoagulant.

    The collection was complete after 12 weeks, and the specimens were sent to the CRO, who performed the analysis and returned the testing to the researcher at the Sponsor. The researcher was concerned by the results, because they did not correlate to the disease state in the same manner as research he had conducted in his own lab. An investigation ensued, and everything from patient specific treatments to lab testing methodology to ischemic times during processing were considered. Still, there was no tangible explanation.

    The researcher requested an additional 10 patients be collected as a last resort. While organizing the materials, the project manager was informed that the K3 tubes were on backorder. The project manager conveyed this information to the researcher, and inquired whether there was a different tube she would like to use. The researcher’s response solved the mystery: K3 EDTA tubes should not have been used in the collection of the specimens. Previous studies had ruled out this collection tube, due to inconsistent activity of this biomarker. A K2 EDTA Plasma tube should have been used in the original study kits.

    Had the project manager involved the researcher in the initial design of the study kits, 14 weeks of enrollment and testing, countless hours of investigation, and significant budget dollars would not have been wasted.

    Clinical operations professionals that maintain the standardization of study supplies instill confidence in the expected results and reproducibility of current and future research.


    4) Develop Clear Instructions and Simplified Labeling

    The benefits of flexible study design can quickly be diminished by complex back-end identification and labeling procedures. Manual identifiers (e.g. scribing study visit details on the cryovial labels) add labor, increase the risk of error and extend ischemic time, yet provide no clear benefit. Standardized label formats and integrated identification sequences (i.e. Parent-to-Child ID formats), supported by clear, concise instructions, will ensure the accountability and quality of the biospecimens.

    Consider: How much information is too much information?

    Study Labels should be formatted to serve the key purpose of accountability and — where automation is planned — barcoded. eCRFs, LIMS, processing logs, and even Excel spreadsheets should be used to capture the secondary and tertiary data. This type of system-wide standardization will help minimize the impact on patient care and office operations.
