Pembrolizumab

How it works

Blocks PD-1, a protein that normally helps cancer cells evade the immune system, allowing the immune system to attack cancer cells.

Cancer types

Colorectal CancerMicrosatellite instability-high (MSI-H) or mismatch repair deficient (dMMR)
Lung CancerAll patients

Efficacy

Studies show that around 50% of patients achieved an objective response, with a median overall survival of approximately 16.9 months.

Side effects

Moderate

Side effects can be significant and may require dose adjustments or supportive medication, but the treatment is usually continued.
