“In a research letter published online in JAMA Oncology, Ryan Stargard et al. conducted a retrospective cohort study evaluating whether the CAR-T therapy is associated with a disproportional increase in second primary malignant neoplasms (SPMN) and T-cell malignant neoplasms (TCMN). The authors queried the FDA Adverse Event Reporting System (FAERS) postmarketing surveillance database for SPMN reports across 6 commercially available CAR-T products.

They identified 8455 AE reports from patients treated with CAR-T therapy, of which 386 reports (4.6%) described SPMN. Most SPMNs reported were myeloid neoplasms (57.0%), followed by solid tumors (29.0%). The TCMNs accounted for 2.8%.

A disproportional increase in SPMN reporting was observed in patients with refractory hematologic malignant neoplasms (HMNs) treated vs untreated with CAR-T therapy (ROR = 2.63; 95%CI 2.34-2.95).

Among 11 TCM reports after CAR-T therapy, large B-cell lymphoma was the most common indication for CAR-T (72.7%); most patients received tisagenlecleucel (54.5%) or axicabtagene ciloleucel (27.3%).

A disproportional increase in TCMN reporting was observed after CAR-T therapy (ROR=3.03; 95%CI 1.49-5.53), and this signal persisted in a sensitivity analysis. Six TCM cases were fatal.”
