Indications for VENCLEXTA:
Chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL), with or without 17p deletion, in patients who have received at least one prior therapy, alone or in combination with rituximab.
Assess for level of tumor lysis syndrome risk; provide prophylactic hydration and anti-hyperuricemics prior to 1st dose. Swallow whole. Take with food and water. Initiate with 5-week ramp-up: 20mg once daily for Week 1, then 50mg once daily for Week 2, then 100mg once daily for Week 3, then 200mg once daily for Week 4, then 400mg once daily for Week 5. Monotherapy: continue 400mg once daily until disease progression or unacceptable toxicity. In combination with rituximab: initiate rituximab after 5-week ramp-up phase and has received venetoclax 400mg for 7 days; give rituximab on Day 1 of each 28-day cycle for 6 cycles and continue venetoclax 400mg once daily for 24 months from Cycle 1 Day 1 of rituximab (see full labeling). Dose modifications for toxicities: see full labeling.
Concomitant strong CYP3A inhibitors at initiation or during dose ramp-up phase.
Risk of tumor lysis syndrome (esp. with high tumor burden, comorbidities, CrCl <80mL/min); perform tumor burden assessment, radiographic evaluation, blood chemistry; correct pre-existing abnormalities prior to initiation. Risk of neutropenia; monitor CBCs during therapy; interrupt or reduce dose if severe. Severe renal impairment or on dialysis. Hepatic impairment: monitor closely. Embryo-fetal toxicity. Pregnancy: avoid; exclude status prior to initiation. Females of reproductive potential should use effective contraception during and for ≥1 month after final dose. Nursing mothers: not recommended.
See Contraindications. Concomitant strong CYP3A inhibitors after ramp-up phase (eg, ketoconazole, conivaptan, clarithromycin, indinavir, itraconazole, lopinavir, ritonavir, telaprevir, posaconazole, voriconazole); avoid use or reduce venetoclax steady daily dose by ≥75%. Avoid concomitant moderate CYP3A inhibitors (eg, erythromycin, ciprofloxacin, diltiazem, dronedarone, fluconazole, verapamil) or P-gp inhibitors (eg, amiodarone, captopril, carvedilol, cyclosporine, felodipine, quercetin, quinidine, ranolazine, rifampin, ticagrelor); consider alternatives; if inhibitor necessary, reduce venetoclax dose by ≥50% and monitor closely. Resume at prior venetoclax dose 2–3 days after discontinuing the inhibitor. Avoid concomitant strong CYP3A inducers (eg, carbamazepine, phenytoin, rifampin, St. John’s Wort) or moderate CYP3A inducers (eg, bosentan, efavirenz, etravirine, modafinil, nafcillin); consider alternatives. Avoid live attenuated vaccines until B-cell recovery. Avoid grapefruit, Seville oranges, and starfruit during treatment. Monitor INR closely with concomitant warfarin. Avoid P-gp substrates with narrow therapeutic index (eg, digoxin, everolimus, sirolimus); if necessary, take ≥6hrs before venetoclax.
Neutropenia, diarrhea, nausea, upper respiratory tract infection, anemia, fatigue, thrombocytopenia, musculoskeletal pain, edema, cough; tumor lysis syndrome.
