argenx Chinese NMPA approval for Vyvgart in CIDP
Yesterday before US market opens, argenx and partner Zai Lab announced China's national medical products administration (NMPA) approved the supplemental (sBLA) for Vyvgart Hytrulo in adults with CIDP. We anticipate approx. $600m in peak sales for CIDP in China, and pencil down 15% royalties to argenx from Zai Lab. Looking ahead, the candidate has been submitted to regulatory agencies in Europe and Japan, with approvals in CIDP expected in 2025, while regulatory submission in Canada is due by YE24. We reiterate our € 530 TP and Accumulate rating.
