CAR-T Approvals Expand Into Earlier Treatment Lines
CAR-T cell therapies, initially approved only for patients who had exhausted multiple prior treatment lines, are increasingly gaining regulatory approval for use earlier in the treatment sequence as long-term durability data accumulates from initial approval cohorts. Novartis and Gilead have both expanded label indications since 2023, moving CAR-T therapies from third-line and later use toward second-line treatment for select leukemia subtypes with poor prognosis under standard chemotherapy. This earlier-line expansion substantially increases the eligible patient population for cell therapy, since far more patients qualify at diagnosis or first relapse than after multiple failed treatment attempts. Earlier-line CAR-T use captured an estimated 24 percent of new cell therapy starts in 2025.
