Dosage Modifications

For a dosing interruption >1 week during the first 5 weeks of ramp-up phase or >2 weeks after completing the ramp-up phase, reassess for risk of tumor lysis syndrome (TLS) to determine if reinitiation with a reduced dose is necessary (eg, all or some levels of the dose ramp-up schedule)

Consider discontinuing treatment for patients who require dose reductions to <100 mg for >2 weeks

Dose reduction schedule (CLL/SLL)

  • Dose at interruption 400 mg: Restart at 300 mg
  • Dose at interruption 300 mg: Restart at 200 mg
  • Dose at interruption 200 mg: Restart at 100 mg

  • Dose at interruption 50 mg: Restart at 20 mg
  • Dose at interruption 20 mg: Restart at 10 mg
  • During the ramp-up phase, continue reduced dose for 1 week before increasing the dose

Tumor lysis syndrome

  • Modify for any occurrence of blood chemistry changes or symptoms suggestive of TLS
  • Withhold the next day’s dose; if resolved within 24-48 hr of last dose, resume at the same dose
  • For any blood chemistry changes requiring >48 hr to resolve, resume at a reduced dose
  • For any events of clinical TLS, resume at a reduced dose following resolution

Grade 3 or 4 nonhematologic toxicities

  • First occurrence: Interrupt dose; once resolved to grade ≤1, resume at same dose; no dose modification is required
  • Second and subsequent occurrences: Interrupt dose; follow dose reduction schedule when resuming treatment after resolution; a larger dose reduction may be used at discretion of physician

Hematologic toxicities (CLL/SLL)

  • Grade 3 or 4 neutropenia with infection or fever, or grade 4 hematologic toxicities (except lymphopenia)
  • First occurrence: Interrupt dose; reduce infection risks with neutropenia by administering G-CSF with venetoclax if clinically indicated; once toxicity resolves to grade ≤1, resume at the same dose
  • Second and subsequent occurrences: Interrupt dose; consider using G-CSF as clinically indicated; follow dose reduction schedule when resuming treatment after resolution; a larger dose reduction may be used at discretion of physician

Hematologic toxicities (AML)

  • Grade 4 neutropenia with or without fever or infection; or Grade 4 thrombocytopenia
  • Occurrence prior to achieving remission: Transfuse blood products, administer prophylactic and treatment anti-infectives as clinically indicated
  • First occurrence after remission (last ≥7 days): Delay subsequent treatment cycle of venetoclax and azacitidine, decitabine, or low-dose cytarabine; monitor blood counts; once resolved to Grade 1 or 2, resume all therapy at same dose
  • Subsequent occurrence after remission (last ≥7 days): Delay subsequent treatment cycle of venetoclax and azacitidine, decitabine, or low-dose cytarabine; monitor blood counts; once resolved to Grade 1 or 2, resume all therapy at same dose and reduce duration by 7 days for each subsequent cycle

Coadministration with strong CYP3A4 inhibitors

  • CLL/SLL
    • Dose ramp-up phase: Contraindicated
    • After ramp-up phase, consider alternative medications or reduce dose to 70 mg (coadministered with posaconazole) and 100 mg (coadministered with other strong CYP3A4 inhibitors)
  • AML
    • Day 1: Reduce to 10 mg
    • Day 2: Reduce to 20 mg

    • Steady daily dose (after ramp-up phase): Reduce dose to 70 mg (coadministered with posaconazole) and 100 mg (coadministered with other strong CYP3A4 inhibitors)
    • Resume venetoclax dose used prior to initiating the CYP3A inhibitor or P-gp inhibitor 2-3 days after discontinuation of inhibitor

Coadministration with moderate CYP3A inhibitor or P-gp inhibitor

  • Reduce venetoclax dose by at least 50%
  • Resume venetoclax dose used prior to initiating the CYP3A inhibitor or P-gp inhibitor 2-3 days after discontinuation of the inhibitor

Renal impairment

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

Dosing Considerations

Patients without 17p deletion at diagnosis should be retested at relapse because acquisition of 17p deletion can occur

TLS risk

  • Consider all patient comorbidities before final determination of prophylaxis and monitoring schedule
  • Assess patient-specific factors for level of risk of TLS and provide prophylactic hydration and antihyperuricemics prior to first dose to reduce risk of TLS
  • Perform tumor burden assessments, including radiographic evaluation (eg, CT scan)
  • Assess blood chemistry (potassium, uric acid, phosphorus, calcium, and creatinine) in all patients and correct preexisting abnormalities prior to initiation; monitor blood chemistries for TLS
  • Reassess risk of TLS when reinitiating therapy after a dosage interruption lasting more than 1 week during the ramp-up phase, or more than 2 weeks after completion of ramp-up
  • Institute prophylaxis and monitoring as needed
  • AML
    • All patients should have WBC<25 x 109/L before to initiation
    • Consider reducing venetoclax starting dose and closely monitor patients with risk factors for TLS (eg, circulating blasts, high burden of leukemia involvement in bone marrow, elevated pretreatment LDH levels, reduced renal function

TLS prophylaxis (CLL/SLL)

            Warnings

            Contraindications

            Strong CYP3A inhibitors at initiation and during ramp-up phase

            Cautions

            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

            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

            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

            In a randomized trial in patients with relapsed or refractory multiple myeloma, the addition of venetoclax to bortezomib plus dexamethasone, resulted in increased mortality; treatment of patients with multiple myeloma with venetoclax in combination with bortezomib plus dexamethasone is not recommended outside of controlled clinical trials

            Drug interaction overview

            • Effects of other drugs on venetoclax
              • Venetoclax is a CYP3A substrate
              • Concomitant use with a strong or moderate CYP3A inhibitor or a P-gp inhibitor increases venetoclax plasma concentrations and toxicities, including the risk of TLS
              • Reduce dose when coadministered with P-gp or moderate CYP3A4 inhibitors
              • Avoid grapefruit products, Seville oranges, and starfruit during treatment, as they contain inhibitors of CYP3A
              • Concomitant use with a strong CYP3A inducer decreases venetoclax plasma concentrations and efficacy
            • Venetoclax effects on other drugs
              • Venetoclax has inhibition potential on P-gp substrates at therapeutic dose levels in the gut; therefore, avoid coadministration with narrow-therapeutic index P-gp substrates
              • Coadministration with warfarin increases warfarin peak plasma concentrations and AUC, which may increase the risk of bleeding; closely monitor INR; monitor international normalized ratio (INR) more frequently in patients using warfarin concomitantly

            Pregnancy

            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

            Pregnancy Categories

            A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

            B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

            C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

            D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

            X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

            NA: Information not available.

            Pharmacology

            Mechanism of Action

            Selective inhibitor of the B-cell lymphoma 2 (Bcl-2) regulator protein, an antiapoptotic protein

            Overexpression of Bcl-2 has been demonstrated in CLL cells where it mediates tumor cell survival and has been associated with resistance to chemotherapeutic agents

            Venetoclax helps restore the process of apoptosis by binding directly to the Bcl-2 protein, displacing proapoptotic proteins like BIM (a novel member of the Bcl-2 family), triggering mitochondrial outer membrane permeabilization, and activating caspases

            Absorption

            Peak plasma time: 5-8 hr

            Peak plasma concentration at steady-state: 2.1 mcg/mL (400 mcg/day)

            AUC at steady-state: 32.8 mcg·hr/mL (400 mcg//day)

            Food effects

            • Administration with a low-fat meal increased venetoclax exposure by ~3.4-fold and administration with a high-fat meal increased venetoclax exposure by 5.1- to 5.3-fold compared withto fasting conditions
            • Venetoclax should be administered with a meal

            Distribution

            Protein bound: >99.9%

            Vd: 256-321 L

            Metabolism

            Metabolized by CYP3A4/5

            M27 was identified as a major metabolite in plasma with an inhibitory activity against Bcl-2 that is at least 58-fold lower than venetoclax in vitro

            Elimination

            Half-life: 26 hr

            Excretion: >99.9% in feces; <0.1% in urine
