Plasma L-Arginine levels assessed by ELISA predict response of cancer patients to immune checkpoint blockers

New highlight in Annals of Oncology!
In this study, Peyraud at al. show that plasmatic level of L-Arginine (Arg) is associated with clinical outcome of patients treated with immune checkpoint blockers (ICB). Using an ELISA approach for Arg quantification (#IS-I-0400R) applied on two independent cohorts, authors demonstrated that low plasmatic level of Arg was associated with a worse clinical outcome.
