Early data of Waldenström’s non-Hodgkin lymphoma patients enrolled in a trial testing Immunitybio Inc.’s off-the-shelf allogeneic CD19 chimeric antigen receptor natural killer cell therapy (CAR-NK), used in combination with anti-CD20 drug rituximab, led to durable complete responses without lymphodepletion.

CAR T cells have made headlines for their ability to fight hematological cancers, but they have proven largely ineffective against solid tumors. To fight such tumors, many groups have engineered T cells to carry T-cell receptors (TCRs) that target cancer antigens, but this approach requires using T cells taken from the patient and it is ineffective against parts of the tumor that have lost expression of the target antigen. As an alternative strategy, researchers at Zelluna ASA in Norway have engineered natural killer (NK) cells to express TCRs against solid tumor antigens.

There was an upbeat message for cell and gene therapy companies in the 2026 industry update presented as the J.P. Morgan Healthcare Conference opened on Monday, with Tim Hunt, CEO of the Alliance for Regenerative Medicine, telling delegates that after lean years of learning, adapting and setbacks, the sector is now self-sustaining.
