Warnings/Precautions

Concerns related to adverse effects:

• Bone marrow suppression: Serious or severe myelosuppression may occur with polatuzumab vedotin treatment. Grade 3 or higher neutropenia, thrombocytopenia, anemia, lymphopenia, and neutropenic fever have been reported. Most patients who received polatuzumab vedotin with rituximab, cyclophosphamide, doxorubicin, and prednisone received primary prophylaxis with granulocyte colony-stimulating factor (G-CSF); almost half of patients who received polatuzumab vedotin with bendamustine and rituximab received primary prophylaxis with G-CSF.

• Hepatotoxicity: Serious hepatotoxicity has occurred; cases were consistent with hepatocellular injury, with elevations of transaminases and/or bilirubin. Grade 3 and 4 transaminase elevations occurred in a small percentage of patients. The risk for hepatotoxicity may be increased with preexisting liver disease, elevated baseline liver enzymes, and concurrent hepatotoxic medications.

• Infection: Serious and/or fatal infection, including opportunistic infections such as sepsis, pneumonia (including Pneumocystis jirovecii and other fungal pneumonia), herpesvirus, and cytomegalovirus have occurred. Prophylaxis for P. jirovecii pneumonia and herpes virus is required throughout polatuzumab vedotin treatment. Grade 3 or higher infection has occurred; infection-related mortality was reported in a small percentage of patients within 90 days of the last treatment.

• Infusion-related reactions: Infusion-related reactions, including severe cases, have been reported. Symptoms included fever, chills, dyspnea, pruritus, rash, and chest discomfort; most reactions were grade 1 or 2 in nature. Infusion reactions may occur as late as 24 hours after administration. Premedicate prior to polatuzumab vedotin administration with an antihistamine and antipyretic.

• Peripheral neuropathy: Polatuzumab vedotin may cause peripheral neuropathy, which may be severe and/or cumulative; may worsen preexisting peripheral neuropathy. Neuropathy may occur as early as the first cycle of therapy. Neuropathy is usually sensory, although motor and sensorimotor peripheral neuropathy has also been observed; the majority of cases were grade 1 or 2 (grade 3 toxicity has also been reported). The median time to onset was 2.1 to 2.3 months; neuropathy completely resolved in approximately one-half of patients, and a majority of patients saw improvement or resolution of neuropathy after a median of 1 or 4 months.

• Progressive multifocal leukoencephalopathy: Progressive multifocal leukoencephalopathy (PML) has been reported with polatuzumab vedotin when used in combination with bendamustine and rituximab.

• Tumor lysis syndrome: Tumor lysis syndrome (TLS) may occur; risk of TLS is higher in patients with a high tumor burden and/or with rapid tumor proliferation.

Vaccines (Live): Immunosuppressants (Miscellaneous Oncologic Agents) may enhance the adverse/toxic effect of Vaccines (Live). Specifically, the risk of vaccine-associated infection may be increased. Immunosuppressants (Miscellaneous Oncologic Agents) may diminish the therapeutic effect of Vaccines (Live). Risk X: Avoid combination

Yellow Fever Vaccine: Immunosuppressants (Miscellaneous Oncologic Agents) may enhance the adverse/toxic effect of Yellow Fever Vaccine. Specifically, the risk of vaccine-associated infection may be increased. Immunosuppressants (Miscellaneous Oncologic Agents) may diminish the therapeutic effect of Yellow Fever Vaccine. Risk X: Avoid combination

Reproductive Considerations

Evaluate pregnancy status prior to use in patients who could become pregnant. Patients who could become pregnant should use effective contraception during treatment and for 3 months after the last polatuzumab vedotin dose. Patients with partners who could become pregnant should use effective contraception during treatment and for 5 months after the last polatuzumab vedotin dose.

Pregnancy Considerations

Based on the mechanism of action and data from animal reproduction studies, in utero exposure to polatuzumab vedotin may cause fetal harm.

Breastfeeding Considerations

It is not known if polatuzumab vedotin is present in breast milk.

Due to the potential for serious adverse reactions in the breastfed infant, breastfeeding is not recommended by the manufacturer during treatment and for 2 months after the last polatuzumab vedotin dose.

Monitoring Parameters

CBC throughout treatment; LFTs (liver enzymes and bilirubin). Verify pregnancy status (in patients who could become pregnant) prior to treatment initiation. Monitor during infusion and for at least 90 minutes after the first infusion and for at least 30 minutes after subsequent infusions for signs/symptoms of infusion-related reactions. Monitor for signs of neuropathy (hypoesthesia, hyperesthesia, paresthesia, dysesthesia, burning sensation, or neuropathic pain or weakness, or gait disturbance), tumor lysis syndrome, signs/symptoms of progressive multifocal leukoencephalopathy (new or worsening neurologic, cognitive, or behavioral changes) and infection (bacterial, fungal, or viral).

The American Society of Clinical Oncology hepatitis B virus (HBV) screening and management provisional clinical opinion (ASCO [Hwang 2020]) recommends HBV screening with hepatitis B surface antigen, hepatitis B core antibody, total Ig or IgG, and antibody to hepatitis B surface antigen prior to beginning (or at the beginning of) systemic anticancer therapy; do not delay treatment for screening/results. Detection of chronic or past HBV infection requires a risk assessment to determine antiviral prophylaxis requirements, monitoring, and follow-up.

Mechanism of Action

Polatuzumab vedotin is an antibody drug conjugate (ADC) directed at CD79b which consists of 3 components: 1) a CD79b-specific humanized IgG1 antibody; 2) a microtubule-disrupting agent, monomethylauristatin E (MMAE); and 3) a protease cleavable linker (which covalently conjugates MMAE to the polatuzumab antibody). The conjugate binds to CD79b (B-cell specific cell surface protein commonly expressed in mature B cell lymphomas [Tilly 2019]), and forms a complex which is internalized within the cell and releases MMAE. MMAE binds to the tubules and disrupts the cellular microtubule network, inducing cell cycle arrest (G2/M phase) and apoptosis.

Pharmacokinetics (Adult Data Unless Noted)

Distribution: Vd: Antibody-conjugated MMAE: 3.15 L.

Protein binding: MMAE: 71% to 77%.

Metabolism: Catabolism to small peptides, amino acids, unconjugated MMAE, and unconjugated MMAE-related catabolites; MMAE is a CYP3A4 substrate.

Half-life elimination: Antibody-conjugated MMAE: ~12 days (at end of cycle 6); unconjugated MMAE: ~4 days (after first dose).

Excretion: Clearance: Antibody-conjugated MMAE: ~0.9 L/day (at end of cycle 6).
