This is just from memory but I believe this agreement provides a potential 'second source' for final purification, lyophilization, fill and finish. Cambrex is doing that job now for Atyrn but perhaps GTC is planning for higher future higher volume requirements for Atryn (:>) ..as well as the ability to handle other products. Also, GTC did have to write off some inventory at the end of Q2 due to some manufacturing problem at their fill and finish contractor so having a 'second source' seems only prudent.
