The integration of formulation design space, real-time GMP manufacturing, and an iterative sequential pharmacokinetic (PK) study in healthy volunteers was successfully applied to develop an HPMC matrix tablet that achieved the desired PK characteristics for SLx-2101.The key formulation variables influencing performance were the range of dose and release rate, hence a two-dimensional (2D) design space was mapped by manufacturing and characterizing four “regulatory batches” bracketing the corners of the compositional ranges.

Conventional human metabolism studies are well understood study designs which help drug companies generate data to support drug development and registration. Variations from conventional study designs can be required as a result of the specific characteristics of individual drugs or the need for particular data to support drug registration. This poster describes scenarios where alternative study designs and approaches have been required.

The aim of the phase 1, single-center, randomized, active-controlled study in healthy volunteers reported in this paper was to investigate the pharmacodynamic effects and safety of different dosing regimens of RDX7675 in humans.

This presentation describes the principles and applications of Translational Pharmaceutics: an R&D platform integrating formulation development, real-time adaptive GMP manufacturing and clinical testing in order to accelerate drug development cycles.
