Risk Levels CLL/SLL:


Low Risk, CLL/SLL

  • Hydration: Oral (1.5-2 L/day) beginning 2-3 days prior to first dose
  • Anti-hyperuricemics: Begin allopurinol 2-3 days prior to first dose
  • TLS Lab Monitoring: Monitor blood chemistries, including potassium, uric acid, phosphorous, calcium, and creatinine, pre-dose for each dose of the ramp-up series. For the first dose of 20 mg and 50 mg, obtain additional lab work 6-8 hours after the first dose, as well as 24 hours after the first dose.

Medium Risk, CLL/SLL

  • Hydration: Oral (1.5-2 L/day) beginning 2-3 days prior to first dose
  • Anti-hyperuricemics: Begin allopurinol 2-3 days prior to first dose
  • TLS Lab Monitoring: Monitor blood chemistries, including potassium, uric acid, phosphorous, calcium, and creatinine, pre-dose for each dose of the ramp-up series. For the first dose of 20 mg and 50 mg, obtain additional lab work 6-8 hours after the first dose, as well as 24 hours after the first dose.
  • Screen for drug-drug interactions - click for link to CLL Dose Modification During Ramp Up with CYP3A Inhibitors chart
  • Consider hospitalization for patients with CrCl < 80mL/min at first dose of 20mg and 50mg

High Risk, CLL/SLL

  • Hydration: Oral (1.5-2 L/day) beginning 2-3 days prior to first dose and IV (150-200 mL/hr) as tolerated.
  • Anti-hyperuricemics: Begin allopurinol 2-3 days prior to first dose. Consider rasburicase if elevated baseline uric acid.
  • TLS Lab Monitoring: Monitor blood chemistries, including potassium, uric acid, phosphorous, calcium, and creatinine. For the first dose of 20 mg and 50 mg, which should be given in the hospital on two separate admissions, obtain lab work pre-dose as well as 4, 8, 12, and 24 hours after administration of the dose. Ensure inpatient staff is aware of the lab orders and the frequency so that labs are not seen as "duplicates" and inadvertently cancelled. For subsequent ramp-up doses, which can be given outpatient, obtain lab work pre-dose as well as 6-8 hours and 24 hours after administration. All labs should be reviewed in "real time" for early detection of TLS.

CLL Dose Modification During Ramp Up with CYP3A Inhibitors
CLL DOSE MODIFICATION DURING RAMP UP WITH MODERATE CYP3A INHIBITORS
Moderate CYP3A Inhibitors include but are not limited to the following:
Ciprofloxacin Erythromycin
Diltiazem Fluconazole
Dronedarone Verapamil
Week 1 10mg
Week 2 20mg
Week 3 50mg
Week 4 100mg
Week 5 200mg
If initiating Moderate CYP3A Inhibitor treatment during Venetoclax treatment, dose reduce Venetoclax by at least 50%, with steady state dosing at 200mg or less.
CLL DOSE MODIFICATION DURING RAMP UP WITH MODERATE CYP3A INHIBITORS
Strong CYP3A Inhibitors include but are not limited to the following:
Clarithromycin Lopinavir
Indinavir Posaconazole
Itraconazole Ritonavir
Ketoconazole Voriconazole

Contraindicated during ramp up of Venetoclax. If use of both Venetoclax and Strong CYP3A is warranted, consider dose interruption/pause of CYP3A treatment during ramp up phase, with final Venetoclax steady state dose of 100mg (complete ramp up at week 4 and continue dosing at 100mg daily for treatment dose). Restart CYP3A treatment once at steady state Venetoclax dose and monitor.

For concomitant Posaconazole, reduce week 4 ramp up Venetoclax dosing from 100mg to 70mg, with 70mg daily as final steady state Venetoclax treatment dose.

If the use of a Strong CYP3A Inhibitor is warranted during Venetoclax treatment, consider dose interruption/pause of Venetoclax treatment for course of Strong CYP3A Inhibitor, then resume Venetoclax dose 2-3 days after discontinuation of Strong CYP3A Inhibitor.

AML - with WBC < 25 x 109/L

In patients with WBC < 25 x 109/L, prophylactic measures below should start 1-2 days prior to treatment:
  • Ensure patient is adequately hydrated (oral hydration for all patients should include 1.5-2 L/day), beginning 1-3 days prior to treatment
  • Premedicate with allopurinol 1-2 days prior to therapy and continue if needed, based on uric acid levels
  • Monitor potassium, calcium, phosphorous, uric acid levels and CrCL to ensure adequate baseline levels prior to start of first dose
  • Once all measures above are taken into consideration, check for drug-drug interactions and modify as needed using chart below - click for link to table
  • Bone marrow assessment recommended at the end of Cycle 1 to measure response
