  • Drug Substance Development Leader, Director at Galapagos
    Apr 2015 - Jan 2022 · 6 yrs 10 mos

    During my Galapagos period my main task was to develop a suitable synthesis (adapted to the phase of development) with external CMOs in order to supply on time the clinical studies. I started to work on the CF projects (in collaboration with AbbVie) for which the drug substance supplies for 10 FiH were done in around 3 years. I worked on the GLPG1972 project in collaboration with Servier (Ph II supplies). I also worked the GLPG1690 project (ziritaxestat) which was unfortunately stopped during the Phase 3. This includes the Ph III clinical supplies as well as the development of a commercial manufacturing process including Registration and Validation Campaigns (Successful Registration Campaign in 2020: 1 MT API produced by external CDMO). Ziritaxestat was in co-development with Gilead.
