Immunotherapy comes of age: Immune aging & checkpoint inhibitors

Elias, Rawad, Karantanos, Theodoros, Sira, Elizabeth, Hartshorn, Kevan L.·2017·Journal of Geriatric Oncology

Abstract

Immune checkpoint inhibitors (ICIs) are based on the understanding that there are multilayered checks and balances which can be manipulated to unleash already existing, but paralyzed, immune responses to cancer. These agents are safer and more efficacious than classic cytotoxic drugs making them a very attractive therapeutic option, especially in older adults. Current available data do not suggest significant age-associated differences in the clinical profile of ICIs. It must be noted, however, that there is still relatively little information on the use of ICIs in adults over 75years of age and aging is associated with a decline in the immune system or "immunosenescence" which theoretically can reduce the efficacy of these immune based therapies. In this paper, we review the mechanism of action of ICIs, current clinical data on their use in older adults, and age-associated immune changes that might have a direct impact on their activity in this population. We chose to focus on mainly adaptive cellular immunity, and especially on components of the immune system that are implicated directly in the immune checkpoint process.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
