Figure 5. Infliximab is released from CHS within FibGen in the presence of plasmin.
Cumulative drug release from FibGen with 320 μg infliximab loaded CHS in the presence of plasmin, a broad spectrum serine proteinase. Infliximab was released from CHS within FibGen in the presence of plasmin, but the rate of release increased after some initial degradation after approximately day 10.
