We thank Wanjie Sun, Donald J. Schuirmann, and Stella Grosser for their detailed review and valuable comments and opinions on Jones et al.

Schuirmann, and Stella Grosser for sharing the information given by the FDA in their final review and agree with them that both the ABE and the RSABE analysis methods show that bioequivalence was met in the APLIOS study.
