We pride ourselves in being a global leader in the development of vaccine & viral vector formulations —whether liquid, lyophilized or spray-dried—for a large variety of ATMP and vaccine types. Our database and algorithms, together with our expertise, help to make the impossible possible and provide tailored and best-in-class formulations for your specific vaccine / virus. Some of our examples in the field of ATMPs and vaccines are shown below.

Case Study – 1 - Liquid

Best-in-class formulations for Ad5 viruses and viral vectors

Internal R&D project implementing an excipient preselection approach, enabling rational formulation development and the generation of best-in-class formulations for Ad5 viruses and viral vectors in liquid.

Case Study – 2 - Lyophilized

Stabilization of human adenovirus (ATMP)

Customer project (oncology) to stabilize human adenovirus in lyophilized form: Leukocare successfully stabilized an adenovirus with undisclosed insert during lyophilization and storage for at least 24 months. After lyophilization titer drop was < 0.3 log; total titer drop during lyophilization and storage was < 0.4 log.

Case Study - 3 - Influenza vaccine

Development of an influenza vaccine as dry powder

R&D collaboration with Christian-Albrechts-University (Kiel, Germany): Development of an influenza vaccine as dry powder to increase stability, enable terminal sterilization, and to utilize alternative routes of administration.
Immune response in non-human primates was fully retained after spray-drying and irradiation with Leukocare formulation compared to non-irradiated original Pandemrix®.
Storage at ambient conditions (25°C and 60% relative humidity) did not show an influence on the antigen integrity and activity.

Immune response in macaques to Pandemrix vaccine (HAI titer), PBS=negative control. *significantly different (p < 0.01) from group 2, 4 and 5 mean titers of groups 2,

4 and 5 were not significantly different from one another (bars represent the geometric mean titer for each group).
