I don't see anything to indicate it's an implant - the prescribing information [1] says it's a subQ injection, and the trial information [2] seems consistent with that.
You're right. I blithely assumed any drug with such a long half-life must have some sort of delayed dose mechanism. But it seems it's just extraordinarily stable and is very, very slowly absorbed. Remarkable.
