On November 9, Novartis AG recorded an Overnight Decline of 3.42%, trading at $154.0 per share, with turnover of $653,400.
The clearest catalyst was the recent disclosure that testing linked two tumor cases to Novartis AG's Zolgensma gene therapy, heightening investor concern over product safety and potential regulatory risk.
According to recent company-related reporting, nine tumor cases have been reported in patients treated with Zolgensma since its approval in 2019, and two cases showed evidence of vector DNA integration into the patient genome. Existing safety information already warns of potential tumor risk associated with DNA insertion. While Novartis AG said it continues to monitor and assess all reported cases, the latest safety development appears more directly tied to the current share weakness than earlier items such as the late-October earnings beat and raised core operating income outlook, which had previously supported the stock.
