Manual and computational methods for the evaluation of statistical predictions based on expert analysis.
  • Raphael Nudelman - Head of Chemical & Computational Toxicology, Teva Pharmaceutical Industries Ltd., Israel
  • William Nye - Account Manager, Lhasa Limited

The ICH M7 guideline recommends the use of two complementary (Q)SAR methodologies, one expert rule-based and one statistical-based, to assess the mutagenicity of impurities. The M7 guideline also urges the use of expert review in order to evaluate the relevance of any computational predictions, and such a manual expert evaluation can potentially overrule positive predictions. Although expert review is carried out in all circumstances it can be more challenging when the expert and the statistical system disagree. This disagreement can potentially result in over-control of non-mutagenic impurities.

Teva and Lhasa Limited are developing a more standardised approach for manual expert review using Derek and Sarah Nexus. This approach can improve the speed and accuracy of expert review and also increase the consistency of the overall outcome. This combined presentation will describe the approach, illustrated with worked examples.

Closing Plenary Session: Rosetta Lander – Philae: A Long-Term Space Project to Land on a Comet
  • Stephan Ulamec - Philae Project Manager, German Aerospace Center, Germany

Philae is a comet Lander, part of the ESA Rosetta Mission to comet 67P/Churyumov-Gerasimenko.  After about ten years of development and a ten-year cruise through the solar system it successfully landed on the nucleus of the comet on November 12th, 2014.

Since the anchoring harpoons, which were expected to fix the lander to ground, did not work, Philae bounced in the low gravity environment, and only came to rest after a 2 hour’s “hop” in an unforeseen area on the comet surface.   Fortunately, the scientific instruments, including cameras, mass spectrometers, a magnetometer and a radar instrument could be operated, and fascinating, unprecedented scientific results have been obtained from the surface of an active comet.

Interplanetary space missions, including a long development phase and elaborated qualification tests do have similarities with pharmaceutical research, where time-spans between the concepts for a new drug until readiness for marketing can be similar.

Rosetta is an ESA mission with contributions from its member states and NASA. Rosetta's Philae Lander is provided by a consortium led by DLR, MPS, CNES and ASI with additional contributions from Hungary, UK, Finland, Ireland and Austria.
