It was recognized by the early PQRI organizers that a formal structure would be required in order to manage the various projects
planned for the institute. After extensive discussions a plan was established to have the institute managed by two governing
bodies: a board of directors vested with administrative management and fiduciary duties and a steering committee responsible
for all activities related to management and direction of scientific activities.
The PQRI board of directors comprises five individuals, three of whom are appointed by the AAPS executive council and two
representing the steering committee. Current practice is that the chairman and vice-chair of the steering committee sit on
the board of directors and provide the link between the two groups. The steering committee itself was set up to provide each
of the member organizations with input into the scientific decision making and project goal setting for the organization.
A system of technical committees and working groups was established by the steering committee to carry out and manage the
projects (See Table 1).

A chart of the current organizational structure of PQRI is provided in Figure 1. Overall, it has changed only slightly from
the arrangement established when the group was incorporated.

Each PQRI project has a working group comprised of subject-matter experts recruited from the member organizations. These working
groups generate, evaluate, and discuss information or data, and develop PQRI recommendations, technical reports, and scientific
papers. They also coordinate conferences, workshops, seminars, and forums to collect input from the larger scientific community
and to share the information they have gathered on the specific subject evaluated.
Each working group operates under the guidance of a technical committee. Currently there are three technical committees within
PQRI that provide technical and scientific guidance, direction and review for PQRI working groups. The technical committees
consist of scientists and regulatory experts from industry and the FDA, and make technical/scientific recommendations to the
The current PQRI technical committees are:
- Development Technical Committee (DTC). The mission of the DTC is to conduct research projects which help to more clearly define
through technical examples and applications the quality by design (QbD) concepts, science or related activities associated
with QbD in the context of drug development. The DTC incorporates projects formerly managed by the Drug Product and Drug Substance
- Manufacturing Technical Committee (MTC). The MTC leverages manufacturing expertise to define science-based approaches that
appropriately integrate risk assessment and encourage innovation and continuous quality improvement in pharmaceutical manufacturing
as well as flexibility in the associated regulatory processes.
- Biopharmaceutics Technical Committee (BTC). The mission of the BTC is to promote research in the area of biopharmaceutics.
Areas of interest include: linkage of in-vitro drug dissolution/release methods to in-vivo drug bioavailability and bioequivalence, methods for the determination of bioavailability and bioequivalence, pharmacokinetic-pharmacodynamic
relationships, and comparative clinical trials.
The activities of past and present technical committees and working groups are presented in Table II. Most teams meet regularly
by conference call and periodically face-to-face. The length of time required for a group to complete a project varies considerably
but often requires many months to complete.
