2009 AAPS Annual Meeting and Exposition<br />

Clinical Pharmacology and Translational Research (CPTR) <strong>Program</strong>ming Track<br />

TUESDAY AFTERNOON SYMPOSIA<br />

2:00 pm – 4:30 pm<br />

Leveraging Prior Quantitative Knowledge<br />

in Guiding Pediatric Drug Development<br />

Symposium<br />

The U.S. Food and Drug Administration and<br />

European Medicines Agency have recently renewed<br />

their call for innovative model-based approaches<br />

to pediatric drug development. It is evident in the<br />

requirements for sponsors to include a modeling<br />

and simulation plan, where applicable, in their<br />

pediatric investigational plans (PIP) and use <strong>of</strong><br />

clinical trial simulations to support pediatric written<br />

request. The key issues facing us today are high<br />

pediatric trial failure rate due to lack <strong>of</strong> powerful and<br />

innovative clinical trial designs, failure to establish<br />

informative pediatric dosing recommendations due<br />

to lack <strong>of</strong> appreciation for differences in exposureresponse<br />

relationship between pediatric and adult<br />

population. Traditionally, studies have focused on PK<br />

differences only. Inappropriate or lack <strong>of</strong> use <strong>of</strong> prior<br />

quantitative knowledge to better design pediatric<br />

development programs. The objectives <strong>of</strong> this<br />

session are to demonstrate through case studies the<br />

value <strong>of</strong> designing pediatric developing programs<br />

using model-based approaches, and demonstrate<br />

through case studies the impact <strong>of</strong> prior quantitative<br />

knowledge on pediatric development/dosing<br />

decisions. This symposium has been aligned with<br />

the symposium, entitled “Strategic Biomarkers for<br />

Treating Diseases in Younger Children Safely and<br />

Effectively” scheduled for Monday, November 9,<br />

2009 at 2:00 pm. The goal <strong>of</strong> this alignment is to<br />

give the attendees a complete overview <strong>of</strong> pediatric<br />

drug development.<br />

OPEN FORUM<br />

Adequacy <strong>of</strong> PK/PD Model Validation<br />

and Simulation<br />

Funded by Grants from<br />

Research (CPTR) Section Open Forum<br />

An additional fee is required to attend this open forum<br />

As PK/PD modeling (M) and clinical trial simulation<br />

(S) are becoming routine in drug development,<br />

success ultimately depends on the robustness<br />

<strong>of</strong> the chosen model. Yet Brendel, et. al. recently<br />

concluded that only 26% to 28% <strong>of</strong> PK and PD<br />

models were adequately evaluated following a<br />

review <strong>of</strong> 324 articles published from 2002 to<br />

2004 (Clin. Pharmacokinet. 2007; 46(3):221-34).<br />

While this article’s conclusion may be subject to<br />

dispute, it does raise a legitimate question on<br />

how much model validation should be practiced<br />

in the M&S community. For example, the following<br />

questions may be considered: what are the<br />

minimum validation requirements for internal<br />

data? Among the more advanced internal validation<br />

methodologies, e.g. bootstrapping, jackknifing,<br />

Monte Carlo simulation, and etc., which approach<br />

is preferred? What is the rationale <strong>of</strong> choosing that<br />

approach? When and how should external validation<br />

be considered? What are the limitations to external<br />

validation and how might these limitations be<br />

overcome? What lessons can we learn from other<br />

industries with regard to validation, e.g. the<br />

aerospace and defense industries? Taking the PK/<br />

PD model validation question one step further,<br />

one might want to consider what type <strong>of</strong> quality<br />

requirements are needed before attempting clinical<br />

trial simulation (CTS)? What types <strong>of</strong> assumption<br />

are considered acceptable? While the successful<br />

examples <strong>of</strong> CTS have been well documented within<br />

the past few years, what lessons can we learn from<br />

them? If you would like to share your opinion with<br />

us, come join us at the 2009 CPTR Open Forum.<br />

We will survey the standards and practices to<br />

probe the questions stated above in greater depth.<br />

The results will be shared with the participants<br />

during the meeting. Similar to last year’s event,<br />

no speakers are planned as the goal is to have<br />

an open discussion among participants about<br />

their experiences and opinions on these topics.<br />

It promises to be a lively evening <strong>of</strong> food, drink,<br />

and exchange <strong>of</strong> scientific ideas. Our intent is<br />

to publish the proceedings in a refereed journal.<br />

Come join us! We look forward to having you in<br />

an enlightening open forum.<br />

WEDNESDAY SUNRISE SESSIONS<br />

7:00 am – 8:15 am<br />

Pharmacogenetics: Methods and<br />

Clinical Applications<br />

Sunrise Sessions<br />

This session will introduce the building tools<br />

and technologies that are currently used in<br />

pharmacogenomics (PGx) testing in laboratory<br />

diagnostics, drug therapy, and drug and biomarkers<br />

discovery. The clinical application <strong>of</strong> molecular<br />

diagnostics and relevant SNPs and gene expression<br />

technology used in PGx will be discussed to<br />

illustrate that patient outcome can be optimized and<br />

adverse drug reactions can be minimized through<br />

a combination <strong>of</strong> genetic testing and serum drug<br />

therapeutic level monitoring.<br />
