How should VENCLYXTO be initiated in AML?
RECOMMENDED INITIATION AND TLS PROPHYLAXIS MEASURES FOR PATIENTS WITH AML1
Rates of TLS with VENCLYXTO plus AZA were low (1%, n=3) and the risk can be managed by following these prophylaxis measures1,2
In Viale-A, 3 patients (1%) experienced TLS (1 case of clinical TLS; all in the VENCLYXTO plus AZA arm)2
All cases occurred in the dose ramp-up period and were resolved with uricosuric agents and calcium supplements without treatment interruption2
Footnotes
*Risk factors for TLS include circulating blasts, high burden of leukaemia involvement in bone marrow, elevated pre-treatment LDH levels, and reduced renal function.1
†VIALE-A was a Phase 3, randomised, double-blind, placebo-controlled study comparing the efficacy and safety of VEN+AZA vs AZA alone in first-line AML patients ineligible for intensive chemotherapy. VEN+AZA reached its primary efficacy endpoints, achieving statistically significant increases in overall survival and composite complete remission rates (CR+CRi) vs AZA alone (P<0.001 for both). In VIALE-A, 66.4% (190/286) patients on VEN+AZA achieved CR+CRi vs. 28.3% (41/145) patients on AZA alone (P<0.001). 43.4% of patients (124/286) on VEN+AZA achieved CR/CRi before cycle 2 compared with 7.6% (11/145) of patients on AZA alone (P<0.001).1,2

DOSING CONSIDERATIONS FOR PATIENTS WITH RENAL OR HEPATIC IMPAIRMENT1
Renal impairment
| SEVERITY | DOSE MODIFICATIONS |
| Mild, moderate or severe | No dose adjustment is needed for patients with mild, moderate or severe renal impairment (CrCI ≥ 15 mL/min and <90 mL/min). Patients with reduced renal function (CrCI <80 mL/min) may require more intensive prophylaxis and monitoring to reduce the risk of TLS at initiation and during the dose-titration phase. VENCLYXTO should be administered to patients with severe renal impairment (CrCI ≥ 15 mL/min and <30 mL/min) only if the benefit outweighs the risk and patients should be monitored closely for signs of toxicity due to increased risk of TLS. |
Hepatic impairment
| SEVERITY | DOSE MODIFICATIONS |
| Mild or moderate | No dose adjustment is recommended in patients with mild or moderate hepatic impairment. Patients with moderate hepatic impairment should be monitored more closely for signs of toxicity at initiation and during the dose-titration phase. |
| Severe | A dose reduction of at least 50% throughout treatment is recommended. These patients should be monitored more closely for signs of toxicity. |
