  2. From Virgil’s Fourth Eclogue Novus ordo seclorum Now comes the final era of the Sibyl’s song; The great order of the ages is born afresh. And now justice returns, honored rules return; Now a new lineage is sent down from high heaven. D. Meininger LakePharma Symposium 4 October 2013 2

  26. Conclusions • Therapeutic Antibodies continue to provide attractive ROI although the market is maturing • Phage display has underperformed as a de novo lead generation platform in comparison to fully human leads from transgenics and humanized leads from normal mice with this trend expected to persist • CMC properties of therapeutic antibodies must be carefully selected for and/or engineered to bias for clinical and commercial maximum success • Bispecifics and ADCs represent compelling growth opportunities • Immunotherapy looks extremely promising in the clinic and will usher in a biologics “golden age” D.
