12. The method according to claim 11 , wherein the non-treatment period is longer than the period between repeated administrations during the treatment session.
13. The method according to claim 1 , wherein the anti-PD-1 antibody is a neutralizing anti-PD-1 antibody, the anti-PD-L1 antibody is a neutralizing anti-PD-L1 antibody and/or the anti-TIM-3 antibody is a neutralizing anti-TIM-3 antibody.
14. The method according to claim 13 , wherein the anti-PD-1 antibody is a human neutralizing anti-PD-1 antibody or a humanized, neutralizing anti-PD-1 antibody.
15. The method according to claim 13 , wherein the anti-PD-L1 antibody is a human neutralizing anti-PD-L1 antibody or a humanized, neutralizing anti-PD-L1 antibody.
16. The method according to claim 13 , wherein the anti-TIM-3 antibody is a human neutralizing anti-TIM-3 antibody or a humanized, neutralizing anti-TIM-3 antibody.
17.
