TIGIT-Blocking Cancer Therapies
Can blocking TIGIT improve cancer immunotherapy outcomes, and which patients benefit?
Following this Track shows whether TIGIT blockade moves from a promising immune-checkpoint strategy toward consistent evidence of patient benefit. It also helps clarify where results may differ across cancer types.

Where it stands now
Main bottleneck
Current evidence contains reviews but no direct trial results, so it does not establish whether TIGIT blockade produces reliable clinical benefit or which patients are most likely to respond.
Watch next
Watch for reported clinical-trial results showing whether TIGIT blockade improves outcomes and safety compared with an appropriate control, with results reported by cancer type or patient group.

Since the previous research note: What the TIGIT immune brake reveals in myeloma and other blood cancers
Previous expectation: TIGIT blockade might help people with blood cancers if its immune effects translated into safe clinical benefit.
What this study adds: This July 2025 review examines solid tumors and places disappointing human monotherapy results beside combination signals and antibody-design questions. Its stated study selection excludes blood cancers.

Since the previous research note: What does CD155 do to tumor cells and immune cells, and where might TIGIT blockade fit?
Previous expectation: TIGIT blockade might offer another treatment route for advanced solid tumors if it safely improved immune activity and patient outcomes.
What this study adds: The June 2021 review shifts attention to TIGIT in blood cancers, with separately identified earlier studies adding myeloma and myelodysplastic-syndrome observations. It does not test the earlier solid-tumor treatment forecast.
