Immunotherapy / PD-1 inhibitorFDA-approvedFirst-line

Keytruda

Generic name: pembrolizumab

How it works

Blocks the PD-1 protein on immune cells, allowing them to recognize and attack cancer cells.

Cancer types

Lung Cancer— All patients
Melanoma— All patients

Efficacy

Studies show that patients treated with Keytruda have a median overall survival of approximately 17.1 months.

Side effects

Mild

Most people tolerate this treatment well. Side effects are generally manageable and do not require stopping treatment.
