A Fast and Fresh Feature for Prospective Biospecimen Collection

Providing the freedom and flexibility to support effective translational research

Who doesn’t want fast and fresh? While revolutionary companies like Amazon and Grubhub weren’t the first services of their kind, they were pioneers in emphasizing the quick delivery of choices to their customers. This approach increased customer satisfaction by minimizing turnaround time.

Additionally, it empowered customers to customize their purchases.

The wisdom of this business strategy can also be applied to translational research, where researchers depend on access to sufficient quantities of high-quality patient samples.

Streamlining the delivery of high-quality, fresh biospecimens collected from a large population minimizes processing delays. This reduces sample variability and ensures more accurate results.

Furthermore, this approach provides greater flexibility to design appropriate study parameters.

This allows for more efficient and cost-effective research, which is essential for maximizing the potential of prospective biospecimen collection.

 

Overcoming the Translational Gap

Bridging the gap between preclinical and clinical research is one of the most challenging steps within the developmental pipeline of therapeutics.

Overcoming this hurdle typically requires identifying lead therapeutic candidates and validating accurate and reliable biomarkers for evaluating safety and efficacy [Hartl 2021].

Relying on retrospectively collected samples poses problems, including compromised sample quality due to delays in post-collection processing and limited access to sufficient numbers of donors.

Ultimately, these factors lead to inaccurate results and conclusions that further erode the efficiency of the translational research process and limit biomarker discovery.

Prospective biospecimen collection and study design represent a more effective and efficient means of procuring biospecimens, enabling translational researchers to establish greater confidence in their results.

Prospective biospecimen collection plays a crucial role in supporting ongoing research efforts. This is especially true in clinical trials where real-time data is invaluable.

By implementing comprehensive prospective biospecimen collection strategies, researchers can greatly enhance the quality of their findings.

The integration of prospective biospecimen collection in research protocols further ensures that the samples are representative and relevant.

Moreover, prospective biospecimen collection allows for timely analyses that can adapt to evolving research questions.

The impact of prospective biospecimen collection on research outcomes cannot be overstated, as it directly influences the reliability of data.

Onsite Collection Delivers Fresh Samples with Minimal Processing Delay

Implementing a robust prospective biospecimen collection framework is essential for driving innovation in biomarker research.

Incorporating it into study designs leads to more impactful scientific discoveries.

Incorporating prospective biospecimen collection into study designs leads to more impactful scientific discoveries.

This emphasis on prospective biospecimen collection ensures that biomarker development is highly relevant to current clinical needs.

The methodologies surrounding prospective biospecimen collection are continuously evolving, enhancing our understanding of disease mechanisms.

To overcome these translational hurdles, Sanguine developed an onsite collection program that effectively streamlines specimen acquisition.

This minimizes delays in sample processing and reduces the detrimental effects of prolonged sample storage.

This approach reduces the detrimental effects of prolonged sample storage.

For instance, researchers can access whole blood donated by their office or lab mates within minutes of collection.

Short turnaround times between collection and measurement can mimic real-world activities like blood glucose measurements.

They can also mean the difference between good and garbage analysis.

This is particularly critical in the case of peripheral blood mononuclear cells (PBMCs), which are those circulating immune cells essential for clinical biomarkers.

In conclusion, prospective biospecimen collection is a vital component of modern biomedical research.

A recent study published by a clinical-stage biopharmaceutical company methodically described the consequences of delayed PBMC processing from whole blood. Using Sanguine’s onsite collection program, they could perform subsequent analyses at time points as short as 2 hours post-collection.

Comparisons to longer 24 and 48-hour time points revealed changes to the biological nature of the sample through altered gene expression.

Studies such as this demonstrate how scientists and clinicians can leverage Sanguine’s unique capability to quickly provide fresh, healthy donor samples, leading to greater accuracy and confidence in subsequent measurements, which are often expensive and time-consuming.

The future of scientific research is increasingly reliant on the principles of prospective biospecimen collection.

 

Building Better Biomarkers

Obtaining fresh samples through an onsite collection program can improve biomarker identification in various modalities, including extracellular vesicles (EVs).

Given that EVs are an increasingly popular target for biomarker discovery, they also undergo changes upon extended delays in processing.

Researchers at a large biopharmaceutical company evaluated the potential of EVs as biomarkers in clinical trials, measuring the technical variability of the RNA content of EVs isolated from serum using Sanguine’s onsite collection services [Srinivasan 2019]. They observed minimal technical variability between EV samples in RNA sequencing experiments, attributing the differences in RNA content to biological variation among individuals, further supporting the use of serum EVs as a biomarker. 

The measurement of monocyte differentiation to proinflammatory M1 or anti-inflammatory M2 macrophages can be used as biomarkers indicative of various disease states. Adalimumab (Humira) is the only TNF-alpha inhibitor presently approved for treating Hidradenitis Suppurativa (HS), an autoimmune skin condition. Scientists at the drug’s developer hypothesized that macrophage differentiation mechanisms may help explain its uniqueness.

They used Sanguine’s onsite collection services to procure blood samples from healthy donors to compare macrophage profiles to HS patients [Cao 2021]. The study identified several key pathways potentially responsible for the effectiveness of adalimumab at treating HS, including changes in macrophage RNA expression profiles to a wound healing-like state and changes in metalloproteinase expression that are consistent with lower inflammatory responses.

 

Create-Your-Own Large and Diverse Population of Donors

Sanguine’s onsite collection program centralizes the collection process and brings it to a location of your choosing, effectively allowing you to create large populations of your own donors. The IL-23 pathway plays a pivotal role in the immunopathogenesis of Psoriasis and is, therefore, the target of many monoclonal antibodies designed to treat the disease [Yang 2021].

To compare the pharmacology of several approved IL-23 inhibitors in plaque psoriasis, researchers needed access to whole blood samples from healthy donors that elicited a relatively high level of pSTAT3 expression, an essential component of IL-23 signaling, in response to stimulation of single chain IL-23 [Zhou 2021]. Because their onsite program provided sufficient numbers of these rather specific donor samples, the researchers determined that their company’s IL-23 inhibitor exhibited superior pharmacology that may have contributed to the differential clinical efficacy among the monoclonal antibodies. 

 

Unlock the Full Potential of Patient Samples

In addition to onsite collection services, Sanguine provides access to a nationwide community of over 70,000 donors that can support extensive population studies by providing sufficient quantities of high-quality samples from patients with diverse conditions and healthy individuals. Additionally, Sanguine facilitates patient access and follow-up collections, enabling you to design prospective biospecimen collection and longitudinal studies. These features provide more flexibility and control over the design of appropriate study parameters, resulting in more reliable and informative data. 

The success of any scientific research project is only as good as the quality of the data and experimental design. Sanguine’s unique approach to translational research has evolved with these factors in mind, allowing researchers to unlock the full potential of patient samples and develop study parameters that are right for them. Collectively, these benefits enhance the efficiency of the translational research process and aid in developing new therapies.
