| Treatment feature . | VO . | Ibrutinib . | Standard chemoimmunotherapy regimens (FCR, BR, OChl) . |
|---|---|---|---|
| Length of therapy | 12 mo | Indefinite | 6 mo |
| Route of administration | Oral (venetoclax) + IV (obinutuzumab) | Oral | IV (exception: chlorambucil = oral) |
| Notable side effects | TLS, cytopenias | Bleeding, atrial fibrillation, hypertension, arthralgias | Cytopenias, immunosuppression |
