The world’s first multiple myeloma cell therapy has it all to do

With Bristol Myers Squibb/Bluebird’s ide-cel, now branded Abecma, making it across the US finish line, investors might glance nervously at how much this BCMA-targeted Car-T therapy is expected to sell. The 2026 forecast is $1.2bn, according to sellside consensus compiled by Evaluate Pharma, a seemingly tall order given that Abecma has surprisingly been indicated for fifth-line use, even though its KarMMa study was in fourth-line patients. Of course, much of the number will be down to Abecma breaking into earlier lines of multiple myeloma, but here toxicity could trip the therapy up: the label lists hamophagocytic lymphohistiocytosis/macrophage activation syndrome and cytopenia in a boxed warning in addition to the cytokine release and neurotoxicities that are standard with Car-T therapies. There is also an impressive list of BCMA-targeting antibodies and cell therapies, including Johnson & Johnson’s cilta-cel, that could soon compete against Abecma. Not that any of this matters for holders of contingent value rights derived from Bristol’s 2019 takeover of Celgene; since the CD19-targeted Car-T therapy Breyanzi failed to be approved before the end of last year, that security has already lapsed.
