Targeting HIF as a Promising Approach to Synergize With Immune Checkpoint Inhibitors

Blocking tumor hypoxia alongside immunotherapy shows mechanistic promise to overcome resistance in solid cancers, supporting near-term clinical trials.

This comprehensive review synthesizes the mechanistic rationale for combining HIF inhibitors with immune checkpoint inhibitors, demonstrating that HIF-mediated immunosuppression is a central driver of ICI resistance in solid tumors and that multiple approved/investigational HIF inhibitors can potentially reshape the tumor immune microenvironment. While primarily a review of preclinical and early clinical evidence, it provides a clear framework for combination therapy trials in hypoxic solid tumors.

Why it surfaced

Timely review consolidating mechanistic rationale for HIF+ICI combination; directly relevant to the large ICI-resistant solid tumor population; clear path to near-term clinical translation.
