Hi Shawn,The 50 fold dilution was decided to be used after discussion with Yixuan and Hongyuan. The attachment is the sample analysis plan amendment that agree to use the 50 fold dilution for pre dilution. If 10 fold dilution is used for pre dilution, a new plan amendment is needed.Enclosed please find all QCed (except for RX518 food effect Group ) data for RX108, RX208 and RX518.
