BE between one injection vs multiple injection products [Design Issues]

Hi, Dear all,
A product A currently is injected weekly for 4 weeks as one treatment term, we would have a slowly release product A (slow-A), which will be injected monthly. Then we would like to access the BE of A injected 4 time vs slow-A injected 1 time. How is this type of BE between one injection vs multiple injection conducted?

Cmax?

sum of AUCA1-4 vs AUC_slow-A?

Is there any guidance from FDA or EMA.

Any help is greatly appreciated.

	That should not be a BE study? Then what should be considered when we develop product from daily injection to weekly as well as weekly to monthly? Edit: Full quote removed.
