Binod Dhakal, MD, an associate professor of medicine in the Division of Hematology at the Medical College of Wisconsin, discusses the mechanism of action of orvacabtagene autoleucel (orva-cel; JCARH125) in multiple myeloma.

Orva-cel is an investigational CAR T-cell therapy product that demonstrated an overall response rate of 91% in heavily pretreated patients with relapsed/refractory multiple myeloma, according to data from the phase 1/2 EVOLVE study (NCT03430011).

The product targets BCMA, which is currently the leading target antigen for CAR T-cell therapies in multiple myeloma, says Dhakal. Compared with idecabtagene vicleucel, orva-cel is a fully humanized product, Dhakal explains. Additionally, although data have not demonstrated that soluble BCMA affects responses to CAR T-cell therapy, orva-cel has a very low affinity for soluble BCMA, concludes Dhakal.
