The research shows an emerging target for the development of novel CAR T-cell immunotherapies. The researchers reported “high rates of durable responses” in most patients who were in high-risk disease subgroups. Idecabtagene vicleucel led to “deeper and more durable responses” than standard regimens in the KarMMa-3 trial. The results showed pembrolizumab was well tolerated, with 23.5% of patients achieving a complete response. All patients had a complete response after the first infusion, while 67% had a complete response after the second infusion.
