While I know that momenta's trial had an Switching Arm, I thought the trial duration was too short (52 weeks) to incorporate that quantity of switches.
There is a need for a full PK, PD, and immunogenicity sampling done after each switch which I thought you would need a decent time for a washout to the previous treatment to be valid.
Hope your right because it doesn't pass the smell test to me.
