ICI-MYOCARDIT-RECHAL v1: We present a pre-validation composite scoring framework for recurrence of immune-related myocarditis (any grade) or new MACE attributed to ICI within 180 days of rechallenge in adult solid-tumour patients who survived an ICI-attributed myocarditis episode and are being considered for rechallenge.
