  • Looking at rocks and soils from a distance, ChemCam on Mars Rover will fire a laser and analyze the elemental composition of vaporized materials from areas smaller than 1 millimeter on the surface of Martian rocks and soils. An on-board spectrograph, with a spectral library, will provide unprecedented detail about minerals and microstructures in rocks by measuring the composition of the resulting plasma -- an extremely hot gas made of free-floating ions and electrons.From 23 feet (7 meters) away, ChemCam will be able to: Rapidly identify the kind of rock being studied (for example, whether it is volcanic or sedimentary); Determine the composition of soils and pebbles; Measure the abundance of all chemical elements, including trace elements and those that might be hazardous to humans; Recognize ice and minerals with water molecules in their crystal structures; Measure the depth and composition of weathering rinds on rocks; and, Provide visual assistance during drilling of rock cores.The rover can send spectral information directly to Earth, it can also uplink information to other spacecraft orbiting Mars.

    3. 3. A Global Problem Requiring Global Solutions About 80% of all API made outside the US Similar trends in Drug Product manufacturing Detection of counterfeit or substandard products often impossible to detect visually – need a technical solution Solutions need to be standardized to facilitate rapid global transfer and adoption What are the roles of industry, government and the pharmacopeia? – How can we work synergistically and avoid duplication of effort? 3
    4. 4. Industry – Counterfeit vs. Substandard Industry needs the most sophisticated and specialized technology Manufacturers must deal with – Sub-standard materials – Reverse-engineered nearly identical copies The latter require specialized tools – Specialized microscopy to assess if the die used in the tablet manufacture was one used by the company – Examination of impurity profiles of API and excipients to correlate with known sources of materials The former are also difficult – can’t be everywhere – how do you find the material and stop its manufacture? 4
    5. 5. Governments - Standardization Can help drive standardization – Unified track and trace in the US – Reach out globally to standardize Need to target a solution that really addresses the issue – Is tracking at the lot level sufficient or a burden that still leaves a gap? – Is tracking at the unit level feasible in a short time frame? Need to develop a compelling global case that the gain is worth the pain 5
    6. 6. Governments – Broad Reach How does one find counterfeits? Tools good enough to rapidly say “hold to assess authenticity” Sufficient people/equipment to check materials entering the country – Very small percentage checked now – Can’t stop the problem if we can’t detect it Technology needs to be standardized, portable, inexpensive and readily available 6
    7. 7. Examples of Tools Available Track and trace technology (e.g., bar code readers) Infrared spectroscopy (mid and near IR) Portable NMR Portable GC-MS Portable x-ray diffraction Microscopes HPLC and other traditional testing equipment 7
    8. 8. The Need for Standardization Identification/verification tools are critical Only as good as the standards against which the material is tested What does good look like, and how do you know? What is a “close enough” match with the database? How do you minimize false positives (manufacturer risks) and false negatives (consumer risks)? Answers require standardization and industry, governments and perhaps standard-setting bodies working together 8
    9. 9. Spectral Libraries – The Need for Standardization Spectral libraries (fingerprints against which the material in question is matched) are no better than the materials and methodology with which they are constructed Materials and products vary – Lot-to-lot differences (impurities, variations in formulation, uniformity of manufacture) – Regional differences (formulations for US, Africa,…) – Changes during the shelf life of a product Methodology varies – Sampling strategies – Protocols for obtaining spectra – Different manufacturers of the same technology – platform and data analysis differences 9
    10. 10. A Role for the Pharmacopeia? USP currently has access to nearly 3000 drug substance and drug product reference materials USP has a global presence, is used in over 140 countries and has worked with many government across the globe As an independent third party, USP can provide confidentiality and global reach Combined with industry and government efforts, may be able to increase the “sets of eyes” out looking for counterfeits May be able to provide some of the standardization needed to make the current tools more effective 10

    15. 15. Summary Counterfeiters are many and sophisticated so the people and equipment trying to stop them need to be as well Standardization is critical to speed and accuracy – Minimize false positives or false negatives Coordination of efforts is critical – Avoid duplication of effort – Avoid missed opportunities to apply technology – Avoid gaps in technology and optimize coverage Technological strategies, in all their manifestations, are critical to success The public expects us to succeed - we need to provide them with the protection they expect and deserve 15
