Hepatic impairment
Mild or moderate (Child-Pugh A or B): No dosage adjustment; monitor more frequently for signs of toxicity or adverse reactions during initiation and ramp-up phases
Severe (Child-Pugh C): Reduce venetoclax dose by 50%; monitor
Child Dose
Renal Dose
Renal impairment
Mild or moderate (CrCl ?15 mL/min): No dosage adjustment necessary
Severe (CrCl <15 mL/min) or patients on dialysis: Recommended dose has not been determined
Administration
Should be taken with food.
Contra Indications
Concomitant use with strong CYP3A4 inhibitors at initiation and during dose titration phase. Administration of live vaccines.
Precautions
Therapy can cause rapid reduction in tumor and thus poses a risk for TLS at initiation and during ramp-up phase in all patients, and during reinitiation after dosage interruption in patients with CLL/SLL; changes in blood chemistries consistent with TLS that require prompt management can occur as early as 6 to 8 hours following first dose and at each dose increase; TLS, including fatal cases, has been reported after a single 20 mg dose
Neutropenia frequently reported; monitor complete blood cell counts throughout treatment period
Fatal and serious infections such as pneumonia and sepsis have occurred; monitor patients closely for signs and symptoms of infection and treat promptly; withhold therapy for Grade 3 and higher infection
Tumor lysis syndrome (TLS), including fatal events and renal failure requiring dialysis, has occurred in previously treated CLL patients with high tumor burden when treated with venetoclax
The risk of TLS is a continuum based on multiple factors, particularly reduced renal function, tumor burden, and type of malignancy; splenomegaly may also increase risk of TLS in patients with CLL/SLL
Do not administer live attenuated vaccines prior to, during, or after treatment until B-cell recovery occurs; safety and efficacy of immunization with live attenuated vaccines during or following therapy have not been studied; advise patients that vaccinations may be less effective
Based on its mechanism of action and findings in animals, may cause embryofetal harm when administered to a pregnant woman
Pregnancy-Lactation
Pregnancy
There are no available human data on use in pregnant women; based on its mechanism of action and findings in animals, may cause embryofetal harm when administered to a pregnant woman
Females of reproductive potential should undergo pregnancy testing before initiation
Animal studies
In mice, venetoclax was fetotoxic at exposures 1.2 times the human clinical exposure based on AUC at the recommended human dose of 400 mg daily
Fertility and contraception
Advise females of reproductive potential to use effective contraception during treatment and for at least 30 days after the last dose
Male fertility may be compromised by treatment
Lactation
Unknown if distributed in human breast milk; advise nursing women to discontinue breastfeeding during treatment and for at least one week after last dose
Interactions
Decreased serum concentration and efficacy with moderate to strong CYP3A4 inducers (e.g. carbamazepine, phenytoin, rifampicin).
Potentially Fatal: Increased serum concentration and risk of TLS with strong CYP3A4 inhibitors (e.g. itraconazole, clarithromycin, ritonavir). May diminish therapeutic effect of live vaccines.

Mode of Action
Venetoclax selectively inhibits B-cell lymphoma-2 (BCL-2), an anti-apoptic protein, resulting to displacement of pro-apoptotic proteins like BIM, initiation of mitochondrial outer membrane permeabilisation, restoration of the apoptotic process or programmed cell death.
