My Objective is…
After this talk, you will have some good
understandings about:
The Global Innovative Pharmaceutical Industry
The Complexity of Drug Development and
Clinical Research
The Role of Data Manager played in Clinical
Research
Challenges and Opportunities in China

Drug Discovery: Finding A Right Target and
Picking Winners
Identify a key:
Mass-screening for hits:
Identify a disease target:
Combinatorial chemistry
High-Throughput

Genomics
Early Phase Development: Use Clinical Pharmacology (CP),
Pharmacokinetics (PK) and Pharmacodynamics (PD) to
find A Right Drug
 PD: What the drug does to the
body
Response (Effect)
Conccentration (ng/mL)
 PK: What the body does to the
drug

“ If it were not for the great
variability among individuals,
medicine might as well be a
science and not an art”

Dilemmas in Modern Medicine
“Every day, doctors diagnose patients and
prescribe the most appropriate drug, and yet
in many cases, the drug won’t work or will
trigger miserable side effects”
- The Wall Street Journal

Clinical Trials of New Drugs
 A high-noise/low yield endeavor
 Requires great care in design and execution
for success
 Expectations often not realized
 50% of phase III trials failed to show positive
results
 Investment needs to be protected
Buy A Good Insurance Policy and
Execute with High Quality

 Due to the large volume of
generics, regulators (sFDA)
concentrate mostly on drug
manufacturing quality
 Minimal experience in true
innovation-based R&D processes
 Complex regulatory processes
subject to frequent policy changes
and political environment
* Include formulation changes

Great Opportunities for Professional Growth
Come From
1. Outsourcing strategy from global companies and CRO
to support global projects
2. R&D center from global companies focused on
penetrating China’s high potential market
3. New Professions: Biostatistics, Programming (SAS
and DBA), Data Management, Pharmacometrics, etc…
