The invention is directed to a method of predicting clinical response of a patient to treatment of a cancer by an immune checkpoint pathway inhibitor, such as an anti-CTLA-4 or anti-PD-1 antibody binding compound. In one aspect the method comprises generating pre- and post-treatment clonotype profiles, determining a number of clonotypes that decrease in frequency between the first and second clonotype profiles, and predicting a lack of responsiveness in the patient to the treatment whenever the number of clonotypes that decrease in frequency is greater than a predetermined value. |
