Adaptable Study Design for Improved PopPK Modeling

Tasso’s end-to-end PopPK solutions enable the optimization of your decentralized clinical trial design.

The remote, patient-centric sampling methodology enables better adherence and facilitates inclusion of more diverse populations, resulting in higher data density and fidelity than can be achieved with a clinic-centric approach. Design the right study for your requirements with the flexibility of our decentralized sampling solution.

  • Collect samples at more timepoints, providing a richer dataset for modeling while enabling a reduction in trial subjects

  • Improved ability to study drugs with long half-lives, long-acting formulations, or episodic clinical endpoints such as migraine or asthma

  • Reduced sample volumes compared to conventional phlebotomy, enabling studies in children and vulnerable populations

The benefits of Tasso solutions for PopPK are clear:

  • Consistent sampling approach for all study participants and across clinical studies, enabling pooling of PK data

  • Sample volumes and formats that suit your logistics and bioanalytical assay workflow requirements

  • Demonstrated stability for room temperature sample shipping and storage results in reduced requirement for specialized equipment, such as refrigerated centrifuges

High quality sample analysis

Patient samples collected using Tasso solutions readily integrate into your bioanalytical workflows. Our precision blood collection systems support precise analytical results on a broad range of investigational compounds, with data collected by scientists on compounds ranging from small molecules to biologics.

Support resources are available for bioanalytical lab procedures using Tasso samples. Tasso offers solutions for the creation of calibration standards and quality control samples, as well as certificates of accuracy and material control for collection devices. There is established regulatory acceptance for capillary and dried blood technologies in the context of PK and PopPK data when the appropriate validations are performed. Tasso can advise on the best practices for successful implementation.

Partnerships for success

Tasso can work with your existing preferred providers for services such as remote dosing, logistics, bioanalysis, or PopPK modeling. If you prefer, Tasso can help you connect with our established network of provider partners. Together, we can facilitate the rapid and successful implementation of your PopPK strategy.

What is population pharmacokinetics for drug development?

PopPK is a well-established mathematical modeling methodology for understanding the observed variability in circulating drug concentrations between individuals, and as a result can minimise the variability in treatment response of patients. With this approach, only a limited number of samples are taken from any given patient, compared to traditional PK rich sampling.

PopPK data can alleviate the need for post marketing commitments to generate further data for specific patient groups based upon intrinsic (body weight, presence and extent of hepatic or renal impairment, genetic polymorphisms) and extrinsic (effect of food on absorption, concomitant medications effect on absorption and/or metabolism) factors, differences in dose, route of administration, etc. Additionally, the lower blood volumes obtained through sparse sampling methods, such as PopPK, facilitate studies in children and vulnerable populations.
