POLIVY™ (polatuzumab vedotin-piiq) POLIVY™ (polatuzumab vedotin-piiq) Safety was also evaluated in 173 adult patients with relapsed or refractory lymphoma who received POLIVY, bendamustine, and either a rituximab product or obinutuzumab in Study GO29365, including the 45 patients with DLBCL described above. In the expanded safety population, the median age was 66 years (range 27 – 86), 57% were male, 91% had an ECOG performance status of 0-1, and 32% had a history of peripheral neuropathy at baseline. Fatal adverse reactions occurred in 4.6% of recipients of POLIVY within 90 days of last treatment, with infection as a leading cause. Serious adverse reactions occurred in 60%, most often from infection. Table 5 summarizes the most common adverse reactions in the expanded safety population. The overall safety profile was similar to that described above. Adverse reactions in ≥20% of patients were diarrhea, neutropenia, peripheral neuropathy, fatigue, thrombocytopenia, pyrexia, decreased appetite, anemia, and vomiting. Infection-related adverse reactions in >10% of patients included upper respiratory tract infection, febrile neutropenia, pneumonia, and herpesvirus infection. 8.2 Lactation Risk Summary There is no information regarding the presence of polatuzumab vedotin-piiq in human milk, the effects on the breastfed child, or milk production. Because of the potential for serious adverse reactions in breastfed children, advise women not to breastfeed during treatment with POLIVY and for at least 2 months after the last dose. 8.3 Females and Males of Reproductive Potential Pregnancy Testing Verify pregnancy status in females of reproductive potential prior to initiating POLIVY [see Use in Specific Populations (8.1)]. Contraception Females POLIVY can cause embryo-fetal harm when administered to pregnant women [see Use in Specific Populations (8.1)]. Advise females of reproductive potential to use effective contraception during treatment with POLIVY and for 3 months after the final dose [see Nonclinical Toxicology (13.1)]. Males Based on genotoxicity findings, advise males with female partners of reproductive potential to use effective contraception during treatment with POLIVY and for at least 5 months after the final dose [see Nonclinical Toxicity (13.1)]. Infertility Based on findings from animal studies, POLIVY may impair male fertility. The reversibility of this effect is unknown [see Nonclinical Toxicology (13.1)]. 8.4 Pediatric Use Safety and effectiveness of POLIVY have not been established in pediatric patients. 8.5 Geriatric Use Among 173 patients treated with POLIVY in Study GO29365, 95 (55%) were ≥65 years of age. Patients aged ≥65 had a numerically higher incidence of serious adverse reactions (64%) than patients aged <65 (53%). Clinical studies of POLIVY did not include sufficient numbers of patients aged ≥65 to determine whether they respond differently from younger patients. 8.6 Hepatic Impairment Avoid the administration of POLIVY in patients with moderate or severe hepatic impairment (bilirubin greater than 1.5 × ULN). Patients with moderate or severe hepatic impairment are likely to have increased exposure to MMAE, which may increase the risk of adverse reactions. POLIVY has not been studied in patients with moderate or severe hepatic impairment [see Clinical Pharmacology (12.3) and Warnings and Precautions (5.7)]. No adjustment in the starting dose is required when administering POLIVY to patients with mild hepatic impairment (bilirubin greater than ULN to less than or equal to 1.5 × ULN or AST greater than ULN). 17 PATIENT COUNSELING INFORMATION Peripheral Neuropathy Advise patients that POLIVY can cause peripheral neuropathy. Advise patients to report to their healthcare provider any numbness or tingling of the hands or feet or any muscle weakness [see Warnings and Precautions (5.1)]. Infusion-Related Reactions Advise patients to contact their healthcare provider if they experience signs and symptoms of infusion reactions, including fever, chills, rash or breathing problems within 24 hours of infusion [see Warnings and Precautions (5.2]. Myelosuppression Advise patients to report signs or symptoms of bleeding or infection immediately. Advise patients of the need for periodic monitoring of blood counts [see Warnings and Precautions (5.3)]. Infections Advise patients to contact their healthcare provider if a fever of 38°C (100.4°F) or greater or other evidence of potential infection such as chills, cough, or pain on urination develops. Advise patients of the need for periodic monitoring of blood counts [see Warnings and Precautions (5.4)]. Progressive Multifocal Leukoencephalopathy Advise patients to seek immediate medical attention for new or changes in neurological symptoms such as confusion, dizziness, or loss of balance; difficulty talking or walking; or changes in vision [see Warnings and Precautions (5.5)]. Tumor Lysis Syndrome Advise patients to seek immediate medical attention for symptoms of tumor lysis syndrome such as nausea, vomiting, diarrhea, and lethargy [see Warnings and Precautions (5.6)]. Hepatotoxicity Advise patients to report symptoms that may indicate liver injury, including fatigue, anorexia, right upper abdominal discomfort, dark urine, or jaundice [see Warnings and Precautions (5.7)]. Embryo-Fetal Toxicity Advise females of reproductive potential of the potential risk to a fetus. Advise females to contact their healthcare provider if they become pregnant, or if pregnancy is suspected, during treatment with POLIVY [see Warnings and Precautions (5.8) and Use in Specific Populations (8.1)]. Females and Males of Reproductive Potential Advise females of reproductive potential, and males with female partners of reproductive potential, to use effective contraception during treatment with POLIVY and for at least 3 months and 5 months after the last dose, respectively [see Use in Specific Populations (8.3)]. Lactation Advise women not to breastfeed while receiving POLIVY and for at least 2 months after the last dose [see Use in Specific Populations (8.2)].

Other clinically relevant adverse reactions (<20% any grade) included: General disorders: infusion- related reaction (7%), Infection: upper respiratory tract infection (16%), lower respiratory tract infection (10%), herpes virus infection (12%), cytomegalovirus infection (1.2%), Respiratory: dyspnea (19%), pneumonitis (1.7%), Nervous system disorders: dizziness (10%), Investigations: weight decrease (10%), transaminase elevation (8%), lipase increase (3.5%), Musculoskeletal disorders: arthralgia (7%), Eye disorders: blurred vision (1.2%) 6.2 Immunogenicity As with all therapeutic proteins, there is a potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors, including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to polatuzumab vedotin-piiq in the studies described below with the incidence of antibodies in other studies or to other products may be misleading. Across all arms of Study GO29365, 8/134 (6%) patients tested positive for antibodies against polatuzumab vedotin-piiq at one or more post-baseline time points. Across clinical trials, 14/536 (2.6%) evaluable POLIVY-treated patients tested positive for such antibodies at one or more post- baseline time points. Due to the limited number of patients with antibodies against polatuzumab vedotin-piiq, no conclusions can be drawn concerning a potential effect of immunogenicity on efficacy or safety. 7 DRUG INTERACTIONS 7.1 Effects of Other Drugs on POLIVY Strong CYP3A Inhibitors Concomitant use with a strong CYP3A4 inhibitor may increase unconjugated MMAE AUC [see Clinical Pharmacology (12.3)], which may increase POLIVY toxicities. Monitor patients for signs of toxicity. Strong CYP3A Inducers Concomitant use with a strong CYP3A4 inducer may decrease unconjugated MMAE AUC [see Clinical Pharmacology (12.3)]. 8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Risk Summary Based on findings from animal studies and its mechanism of action [see Clinical Pharmacology (12.1)], POLIVY can cause fetal harm. There are no available data in pregnant women to inform the drug-associated risk. In animal reproduction studies, administration of the small molecule component of POLIVY, MMAE, to pregnant rats during organogenesis at exposures below the clinical exposure at the recommended dose of 1.8 mg/kg POLIVY every 21 days resulted in embryo-fetal mortality and structural abnormalities (see Data). Advise a pregnant woman of the potential risks to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2–4% and 15–20%, respectively. Data Animal Data No embryo-fetal development studies in animals have been performed with polatuzumab vedotin- piiq. In an embryo-fetal developmental study in pregnant rats, administration of two intravenous doses of MMAE, the small molecule component of POLIVY, on gestational days 6 and 13 caused embryo-fetal mortality and structural abnormalities, including protruding tongue, malrotated limbs, gastroschisis, and agnathia compared to controls at a dose of 0.2 mg/kg (approximately 0.5-fold the human area under the curve [AUC] at the recommended dose).
