Why are global GMPs so significant?
Everyone on the same page
Minimize culture effects
e.g. single signatures of critical steps in Europeand double signatures of critical steps in US

Speaking of Global, as inCompetition
China is expected to become the fifth largestpharmaceutical market in the world, doubling itspresent $12 billion in sales by the end of the
decade.

Until recently, Chinas pharmaceutical industryhas largely focused on generic manufacturingand counterfeiting of brand name drugs.
But now the Chinese pharmaceutical industry isshifting from imitation to innovation, with morethan 5000 research and development
institutions including 500 to 1000 biotechcompanies. More than 20 biotech parks can befound throughout the country

And finally, regarding China
More than 3700 manufacturers are certifiedin Chinese Good Manufacturing Practices(GMP) standards

Technology is changing
More technical tools are available Near IR for sampling/ID
Airport scanning devices have been considered
for cleaning validation (advantage is speed ofdetermining whether surfaces are truly clean)but have not worked out in actual practice inpharmaceutical applications so far
Total Organic Carbon-is being used widely forwater analysis and cleaning validation studiesespecially for cleaning agents

Speed of Analysis
Time is money
Time is also delaying justice North Carolina currently has such a large
backlog of samples in the labs of the StateBureau of Investigation (SBI) that habitualfelons are having to be released and then arebeing rearrested multiple times for committing
additional felonies while awaiting trial. (Trialcannot proceed until all evidence, including labanalysis, is available)

Excerpt from Drug Discovery &Development (February 2006)
Title of Article = Crafting Smaller andFaster Technologies
The high-throughput mass spectrometry(HTMS) system allowed them to cut samplepreparation time from 30 seconds to 3seconds.
Everything boils down to speed

Additional quotes from same article
The Ultra Performance LC was designed fromthe ground up to reduce run times by up to10 times using low-dispersion, high speed
detectors and 1.7 m small particlechemistries for columns

and
The chemists come up and say they now trythings that theyve never tried before orhardly ever tried before because of time
constraints and because of the cost of thecompound to run a reaction on a certainscale and have it fail.

In my opinion
It is time to steal technology from otherindustries just as we took dust collectors(Torits) from the lumber industry and
clean-in-place (CIP) technology from thedairy industry
Specifically, Im speaking of applyingbioluminescence (ATP ADP + light)from the food industry and apply it topharmaceutical surfaces

Microbial Analysis
Has always been slow (by the time we getthe results of our water testing it is too lateto do anything about it)
We need to borrow the new bioluminescenttechnology being used by the food industryto evaluate cleaned surfaces in restaurants
and food preparation areas for microbiallevels

APIs, Contaminants, Counterfeiting, andBioterrorism Issues
Cleaning or contamination issues arepotentially very great in our raw materials. Why can they make the APIs so cheaply in
other countries? (This is an era where we canbuy mfging equipment on e-bay)
How good are we at detecting contaminants inour raw materials, particularly bioactive or
highly toxic impurities? Are our assays (whichare based mainly on assay of knownconstituents) good enough in all cases?

Some Myths in Cleaning Validation(Reference: Destin LeBlanc, PharmTech Europe, Dec 2005
and Feb 2006
1. Regulatory authorities do not like rinsesampling
2. You must correlate rinse sampling results
with swab sampling results3. You cannot use nonspecific analytical
methods
4. If you use total organic carbon (TOC) youmust correlate it with a specific methodsuch as HPLC (continued on next slide)

Some Myths in Cleaning Validation(continued from previous slide)
5. Any measured residue is unacceptable
6. Dose-based calculations are unacceptable
7. Recovery percentages of different spikedlevels should be linear
8. You cannot validate manual cleaning
