Immunotherapy / PD-1 inhibitorPhase 3 trialInvestigational

PDR001

Generic name: pembrolizumab

How it works

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

Cancer types

Melanoma— All patients

Efficacy

Studies show that pembrolizumab can improve overall survival in patients with advanced melanoma, with a median overall survival of approximately 10.5 months.

Side effects

Moderate

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