PARP inhibitorPhase 3 trialInvestigational

PARP inhibitor

How it works

Blocks the repair of DNA damage in cancer cells, causing them to die.

Cancer types

Prostate Cancer— Patients with BRCA mutations

Efficacy

Studies show that PARP inhibitors can improve overall survival in around 30% of patients with BRCA mutations.

Side effects

Moderate

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