    摘要: The invention provides a method of treating a melanoma comprising (i) identifying a patient having a PD-L1 positive melanoma and (ii) administering to the patient an anti-PD-1 antibody or an antigen-binding portion thereof (“an anti-PD-1 antibody monotherapy”). The methods of the invention can extend progression-free survival for over 12 months and/or reduces the tumor size at least about 10%, about 20%, about 30%, about 40%, or about 50% compared to the tumor size prior to the administration.

    摘要: Fibronectin type III (10Fn3) binding domains having novel designs that are associated with reduced immunogenicity are provided. The application describes alternative 10Fn3 binding domains in which certain immunogenic regions are not modified when producing a binder in order to maintain recognition as a self antigen by the host organism. The application also describes 10Fn3 binding domains in which HLA anchor regions have been destroyed thereby reducing the immunogenic contribution of the adjoining region. Also provided are 10Fn3 domains having novel combinations of modified regions that can bind to a desired target with high affinity.
