ABSTRACT

Introduction: OX40 is checkpoint inhibitor in cancer that coordinates the downregulation of the proliferation of antigen-specific lymphocytes. There is a great need to discover and develop new therapies focused on inhibiting the action of OX40 and consequently improving the immune response in the various types of cancer. Authors of patent US2018256711A1 propose a method to eradicate cancer that utilizes anti-OX40 agonist antibody in combination with anti-PD-L1 antagonist antibody.

Areas covered: Patent US2018256711A1 describes a method of cancer combinatorial treatment consisting of the utilization of a pharmaceutical cocktail containing anti-OX40 and an anti-PD-L1 antibody.

Expert opinion: The results of the clinical trials only support trials regarding the tolerability of combinatorial therapy, even when the objectives of determining the safety and pharmacokinetics of the treatment are proposed.
