Consulting in pharmaceutical development

We can give you some advice in your strategy of pharmaceutical development with our scientific and pharmaceutical experts :

Scientific and regulatory advice in pharmaceutical development (CMC)

  • Strategies for physico-chemical properties of PA, excipients and PF
  • Developing analytical methods for search and identification of impurities (including genotoxic impurities)
  • Setting up of the corresponding specifications for the PA and PF
  • Setting up of chemical and physical stability studies for PA / PF
  • Advice in the way to answer questions raised by regulatory agencies (EMEA, FDA...)

advice in preparation of the scientific content of CTD and DMF including during clinical phases (IND and IMPD).
