Additional safety and drug interactions1
- Hypersensitivity to the active substance or to any of the excipients
- Concomitant use of strong CYP3A inhibitors at initiation and during the dose‑titration phase
- Concomitant use of preparations containing St. John’s wort
- Safety in patients with severe renal impairment (CrCl <30 mL/min) or on dialysis has not been established, and a recommended dose for these patients has not been determined. VENCLYXTO should be administered to patients with severe renal impairment only if the benefit outweighs the risk and patients should be monitored closely for signs of toxicity due to increased risk of TLS
- A dose reduction of at least 50% throughout treatment is recommended for patients with severe hepatic impairment
- Concomitant use of VENCLYXTO with strong CYP3A inhibitors (eg, itraconazole, ketoconazole, posaconazole, voriconazole, clarithromycin, ritonavir) at initiation and during the dose‑titration phase is contraindicated
- Concomitant use of VENCLYXTO with strong or moderate CYP3A inhibitors (eg, ciprofloxacin, diltiazem, erythromycin, fluconazole, verapamil) increases VENCLYXTO exposure and may increase the risk for TLS at initiation and during the dose‑titration phase and for other toxicities. Consider alternative treatments
- Grapefruit products, Seville oranges, and starfruit (carambola) should be avoided during treatment with VENCLYXTO as they contain inhibitors of CYP3A
- Patients should be monitored closely for signs of toxicities and the dose may need to be further adjusted
- Resume the VENCLYXTO dose that was used prior to initiating the CYP3A inhibitor 2 to 3 days after discontinuation of the inhibitor
- Concomitant use of VENCLYXTO with strong CYP3A inducers (eg, carbamazepine, phenytoin, rifampin) or moderate CYP3A inducers (eg, bosentan, efavirenz, etravirine, modafinil, nafcillin) should be avoided
- Alternative treatments with less CYP3A induction or without CYP3A inhibition should be considered
- Preparations containing St. John’s wort are contraindicated during treatment with VENCLYXTO, as efficacy may be reduced
CLL=chronic lymphocytic leukemia; 1L=first line; 2L+=second line + later lines of therapy; O+Clb=obinutuzumab + chlorambucil; HR=hazard ratio; CI=confidence interval; PFS=progression‑free survival; BR=bendamustine + rituximab; VEN+R=VENCLYXTO + rituximab; CYP3A=cytochrome P450 3A; CrCl=creatinine clearance; TLS=tumor lysis syndrome.
