The discovery of immune checkpoints that regulate immune responses transformed cancer care, and the impact that the new class of immune checkpoint inhibitors (ICIs) has had in oncology cannot be understated. A proportion of patients achieve remarkable and durable responses and improved overall survival with use of the current ICIs. However, there are a number of limitations associated with the current immunotherapies, patient outcomes are still suboptimal, and new options are needed to maximize the potential of cancer immunotherapy as the fourth treatment pillar in oncology. New rational combinations leveraging synergies between old and new checkpoints have emerged, with inhibitory targeting of T-cell immunoreceptor with immunoglobulin and immunoreceptor tyrosine–based inhibitory motif domains (TIGIT) along with the PD-L1/PD-1 pathway as one potential strategy under extensive investigation across different cancers. To realize the potential of anti-TIGIT checkpoint inhibition, build upon previous advances in cancer immunotherapy, expand into more tumor types and earlier stages of disease, and provide new treatment options in areas of high unmet need to more patients with cancer, it is essential for those involved in the care of patients with solid tumors to become familiar with this novel therapeutic approach and develop competence related to its clinical integration, enabling rapid translation from discovery to the clinic. This educational activity features an expert discussion of the rationale and mechanism of action of agents targeting TIGIT, enhanced with engaging three-dimensional explanations, and provides practical guidance to identify patients most likely to be the best candidates for novel ICI-based treatment approaches. Upon completion of this activity, participants should be better able to: Describe the rationale for use, mechanisms of action, and preclinical and clinical evidence supporting the use of novel ICIs, such as antibodies targeting TIGIT, and synergistic ICI-based combinations showing promise in overcoming the limitations of current immunotherapies and expanding the benefits to more patients with solid tumors, Identify patients who are most likely to be the best candidates for novel ICI-based treatment approaches, including dual-targeted inhibition of TIGIT and anti–PD-L1/PD-1, based on clinical evidence, biomarker status, comorbidities, patient preferences for chemotherapy-free treatment options, and other relevant factors, working collaboratively as a healthcare team.
