Innovations in Microsampling Technologies to Advance Clinical Trial Design
As drug modalities evolve in complexity with multiplexed mechanisms of action, the need for frequent sampling of patients to monitor the safety and efficacy becomes critical. Since patient samples are a limiting factor, microsampling has become increasingly employed in drug trials to mitigate the burden on patients. Microsampling is also used in pediatric trials when volume is limited due to the smaller size of children. However, traditional bioanalytical assays require significant sample volume to reliably measure patient status. Fortunately, advances in bioanalytical instrumentation have allowed for the use of microsampling in the key bioanalytical readouts of efficacy and safety.
