BTK inhibitorFDA-approvedInvestigational

Ibrutinib

How it works

Blocks the BTK enzyme, which is involved in B-cell receptor signaling and cancer growth.

Cancer types

Leukemia— All patients
Breast Cancer— All patients

Efficacy

In clinical trials, around 70% of patients achieved a complete or partial response, with a median progression-free survival of approximately 17 months.

Side effects

Moderate

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