GENSCRIPT BIO (01548) experienced a significant intraday surge, with its stock price soaring 14.99% at the market open on Wednesday.
The sharp increase was primarily driven by positive preliminary clinical data announced by its associate company, Legend Biotech. Legend reported encouraging results for its investigational in vivo CD19/CD20 dual-targeting CAR-T cell therapy, LB2501, in patients with relapsed or refractory B-cell non-Hodgkin lymphoma.
The promising data, which is scheduled for a late-breaking oral presentation at the upcoming European Hematology Association (EHA) 2026 Congress, triggered a more than 42% jump in Legend Biotech's US-listed shares overnight. This positive sentiment directly impacted GENSCRIPT BIO, as the market reacted to the potential progress in this innovative CAR-T therapy developed using Legend's proprietary TaVec™ platform.
