This was the first DARQA day dedicated to Advanced Therapy Medicinal Products (ATMPs). We were joined by speakers not just from the Netherlands but also from the UK and Sweden. The day had a real GXP feel thanks to the input from all our DARQA committees.

Hans de Konning made sure that the day ran smoothly and that everyone had the opportunity to ask their questions.

Christine Mitchell (ChrisalisQAdvice) gave a general introduction to ATMPs and how they are classified. She also discussed some TIPs for getting advice from the EMA and where you could find general information on their website. She also pointed out the need for risk assessment and a good robust strategy for the drug development path to avoid surprises and additional work along the way (“Begin with the end in mind” Stephen Covey).

Ion Tcacencu (Venn Life Sciences) gave an interesting presentation relating to the pre-clinical side. He also emphasised the need for a risk-based strategy and indicated that specific animal disease models may be required for this work. Although for safety studies Good Laboratory Practice should apply, he indicated that there have been market approvals for some products where the studies were not all performed in a GLP endorsed test facility.

Flow-cytometry is often used to both characterize ATMPs and also for assessment of samples taken from subjects during the clinical trials. Marie Geerlings (Ardena) gave a very clear overview of how flow cytometry works and some valuable TIPs for auditing this type of analysis.

Thilo Buck (Progress Experts in Life Sciences) took us up to the lunch with a presentation on Good Manufacturing Practices and Beyond: Essential Regulatory insights for ATMPs. Although there is a specific GMP guidance for ATMPs there are still some grey areas for example how should ANNEX I be applied for ATMPs. He gave the audience a great overview of the different regulations that need to be considered.

After lunch we continued with the theme of manufacturing. Marc Kamp (Kite Pharma) Presented some real-life situations relating to both manufacturing of ATMPs and the logistics behind the transport etc. This can be quite complex as it often involves personalized drugs and transport across the globe. For ATMPs it is essential that the time for manufacture is reduced to the absolute minimum to ensure the timely transfer back into the patient.

Katie Brock (Kite Pharma) continued with a session on clinical studies and ATMPs. She indicated the need for additional approvals like GMO approval and ensuring that for ATMPs often a tissue establishment licence is needed. In these trials internally as well as on the site many parties are involved. Training of internal staff, clinical staff as well as CRO CRAs in the use of ATMPs and the specific requirements for GCP is important. Finally Eveline Krijger (Acerta Pharma) and our new DARQA chairperson, presented some of the quality challenges related to the QMS, monitoring and auditing of the clinical trials with ATMPs. For example, selecting high risk sites for investigator site audits when there is a single dose of IMP and the recruitment period is short. The day finished with a lively Q&A session involving all speakers. We are all still learning a lot about ATMPs and how we may need to change our approach to the standard way of working. The more we know and understand about these products, the faster we will be able to develop these exciting new medicines to help those who need them most. I hope that DARQA will continue to follow the journey of ATMPs in the future.
