ABSTRACT
BACKGROUND: In recent years the global landscape of pharmaceutical development has evolved drastically in order to adapt to innovative products such as immunotherapy, regenerative medicines and cell and gene therapy, all offering the hope to cure numerous untreated diseases. The global COVID-19 pandemic also led competent authorities in charge of approval of new medicines to implement adapted regulatory pathways allowing early access to innovative treatments and vaccines. New challenges are to be overcome, it is the short development time, or the small patient populations, or again drug product features requiring complete new production, testing and distribution strategies. OBJECTIVE: This paper provides a short overview of the different adaptations required to allow the development of such innovative medicines. METHOD: Several drug development strategies for products under clinical development or recently approved were assessed. RESULTS: Fully integrated strategies encompassing research, non-clinical, clinical and product manufacturing development along with adapted regulatory pathways, anticipation of market access and supported by risk based are important. In such fast pace, the development of relevant manufacturing processes and test methods assessing quality, safety and efficacy of new drugs falls on the critical path and requires particular attention, anticipation and detailed planning as early as possible in order to ensure successful filing and approval. CONCLUSION: Insights within innovative products approved recently reveal the importance of defining a solid chemistry manufacturing and control strategy early on as part of clinical development. Interactions with agencies at key milestones of development are also essential to reduce risks, prioritize development to support safety and allow early access to patients.
