WT Suggest you chk the drugs in development for IgaN as at least one Co I know has a LN P 3 trial ready to go another is I think is in P2 trials. The data so far may be better than Lupy's . Probably at least 3 yrs until either of these has an approved new LN drug ....however AUPH won't de making a profit until 2nd half 2024 ......and then possible face competition from a new drug approved for both IgaN and LN two and a half years later . If U want to know the others Co's ask me on another board Good luck Kiwi
