But J&J's drug is walking away with a notable edge over its rival. They add more options to a growing arsenal of treatments that have helped improve outcomes for people with multiple myeloma. But the new approvals also give J&J's therapy, which was developed with Legend Biotech, a clear advantage over Bristol Myers's drug. J&J's drug has gradually gained ground over Abecma in the CAR-T market for multiple myeloma, even though it first entered the market a year later. With the new approval on Friday, Jefferies' Shi expects J&J's drug to win the majority of that market share.
