Atezolizumab is an Fc-engineered, humanized, non-glycosylated IgG1 kappa immunoglobulin that has a calculated molecular mass of 145 kDa. Hyaluronidase (human recombinant) is an endoglycosidase used to increase the dispersion and absorption of co-administered drugs administered subcutaneously. It is a glycosylated single-chain protein produced by mammalian (Chinese Hamster Ovary) cells containing a DNA plasmid encoding for a soluble fragment of human hyaluronidase (PH20). Hyaluronidase (human recombinant) has a molecular weight of approximately 61 kDa. TECENTRIQ HYBREZA (atezolizumab and hyaluronidase-tqjs) injection for subcutaneous use is a sterile, preservative-free, clear and slightly opalescent, and colorless to slightly yellow solution in single-dose vials. Each 15 mL single-dose vial contains 1,875 mg of atezolizumab, 30,000 units of hyaluronidase, histidine (46.5 mg), methionine (22.4 mg), polysorbate 20 (9 mg), sucrose (1,232 mg), and water for injection, adjusted to pH 5.8 with acetic acid.

If the TECENTRIQ HYBREZA dose is not administered immediately, refer to "Storage Instructions" [see Dosage and Administration (2.6) ]. Remove the vial from the refrigerator and allow the solution to acclimate to room temperature. Visually inspect for particulate matter and discoloration prior to administration. Discard the vial if the solution is cloudy, discolored, or visible particles are observed. Do not shake, freeze, or dilute. The unpunctured vial may be stored at room temperature in ambient light for a maximum of 4 hours prior to the preparation for administration. Use an 18-gauge transfer needle and syringe to withdraw the entire contents of the TECENTRIQ HYBREZA solution from the vial. Discard the vial and any residual drug remaining. TECENTRIQ HYBREZA is compatible with stainless steel transfer and injection needles, and polypropylene, polycarbonate, polyvinyl chloride, and polyurethane syringe material and subcutaneous administration sets. Remove the transfer needle from the syringe and replace it with a subcutaneous administration set (e.g. winged/butterfly) containing 23-gauge, 24-gauge, or 25-gauge hypodermic needle and with a priming volume that does not exceed 0.5 mL for administration. Prime the subcutaneous administration line with TECENTRIQ HYBREZA to eliminate the air in the line and stop when the fluid reaches the needle. Ensure the syringe contains exactly 15 mL of TECENTRIQ HYBREZA after priming the administration line by expelling any excess volume from the syringe. Administer immediately to avoid needle clogging. Discard any unused portion remaining. 2.6 Storage Instructions Do not store the prepared syringe that has been attached to the already-primed subcutaneous administration set. If the prepared syringe containing TECENTRIQ HYBREZA is not for immediate use, do not attach a subcutaneous administration set. The capped syringe may be stored at room temperature [at up to 25°C (77°F)] in ambient room lighting for up to 8 hours and in the refrigerator [2°C to 8°C (36°F to 46°F)] for up to 72 hours. Do not shake or freeze. If the prepared syringe is stored at 2°C to 8°C (36°F to 46°F), allow the syringe to acclimate to room temperature prior to administration.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action PD-L1 may be expressed on tumor cells and/or tumor infiltrating immune cells and can contribute to the inhibition of the anti-tumor immune response in the tumor microenvironment. Binding of PD-L1 to the PD-1 and B7.1 receptors found on T-cells and antigen presenting cells suppresses cytotoxic T-cell activity, T-cell proliferation and cytokine production. Atezolizumab is a monoclonal antibody that binds to PD-L1 and blocks its interactions with both PD-1 and B7.1 receptors. This releases the PD-L1/PD-1 mediated inhibition of the immune response, including activation of the anti-tumor immune response without inducing antibody-dependent cellular cytotoxicity. In syngeneic mouse tumor models, blocking PD-L1 activity resulted in decreased tumor growth. In mouse models of cancer, dual inhibition of the PD-1/PD-L1 and MAPK pathways suppresses tumor growth and improves tumor immunogenicity through increased antigen presentation and T-cell infiltration and activation compared to targeted therapy alone. Hyaluronan is a polysaccharide found in the extracellular matrix of the subcutaneous tissue. It is depolymerized by the naturally occurring enzyme hyaluronidase. Unlike the stable structural components of the interstitial matrix, hyaluronan has a half-life of approximately 0.5 days. Hyaluronidase increases permeability of the subcutaneous tissue by depolymerizing hyaluronan. In the doses administered, hyaluronidase in TECENTRIQ HYBREZA acts transiently and locally. The effects of hyaluronidase are reversible and permeability of the subcutaneous tissue is restored within 24 to 48 hours. 12.2 Pharmacodynamics The exposure-response relationship and time course of pharmacodynamic response for the safety and effectiveness of atezolizumab and hyaluronidase have not been fully characterized. 12.3 Pharmacokinetics When comparing atezolizumab exposure following subcutaneous TECENTRIQ HYBREZA to that of intravenous atezolizumab in Study IMscin001 [see Clinical Studies (14.1) ], the geometric mean ratio (GMR) (90% CI) for Cycle 1 C trough was 1.05 (0.88, 1.24) and AUC 0-21days was 0.87 (0.83, 0.92); the steady state C trough was 1.15 (1.05, 1.26) and AUC was 1.01 (0.94, 1.08) . Steady-state was achieved 6 to 9 weeks. The systemic accumulation ratio following administration of the approved recommended dosage of TECENTRIQ HYBREZA was 2.2. Absorption The mean absolute bioavailability (CV%) of atezolizumab was 72% (83%) and the median time (range) to reach maximum atezolizumab concentration (T max ) was 4.5 (2.2, 9) days. Distribution The volume of distribution of atezolizumab at steady state was 6.9 L. Elimination The atezolizumab clearance (CV%) was 0.2 L/day (29%) and the terminal half-life was 27 days. Atezolizumab clearance decreased over time, with a mean maximal reduction (CV%) from baseline value of 17% (41%); this decrease in clearance is not considered clinically significant. Specific Populations No clinically significant differences in the pharmacokinetics of atezolizumab were observed based on age, body weight, sex, albumin levels, tumor burden, region, race, mild or moderate renal impairment (estimated glomerular filtration rate 30 to 89 mL/minute/1.73 m 2 ), mild hepatic impairment (bilirubin ≤ ULN and AST > ULN or bilirubin > 1 to 1.5 × ULN and any AST), moderate hepatic impairment (bilirubin >1.5 to 3× ULN and any AST), level of PD-L1 expression, and performance status. 12.6 Immunogenicity The observed incidence of anti-drug antibodies (ADA) is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of ADA in the studies described below with the incidence of ADA in other studies, including those of TECENTRIQ HYBREZA or of other atezolizumab products or hyaluronidase products. During the first year of treatment in the Study IMscin001 [see Clinical Studies (14.1) ], the incidence of anti-atezolizumab antibodies was 20% (43/221) and the incidence of neutralizing antibodies (NAb) in ADA-positive patients was 54% (21/39) for TECENTRIQ HYBREZA. The corresponding incidence of ADA was 14% (15/108) and NAb was 60% (9/15) for intravenous atezolizumab. In Study IMscin001, atezolizumab clearance increased by 29% in patients who received TECENTRIQ HYBREZA and who tested positive for ADA, compared to patients who tested negative for ADA; this change in clearance is not expected to be clinically significant. Because of limited immunogenicity data the effect of anti-atezolizumab antibodies on the effectiveness of TECENTRIQ HYBREZA is unknown. There was no identified clinically significant effect of anti-atezolizumab antibodies on the safety of TECENTRIQ HYBREZA during the first 6 months of treatment. In Study IMscin001, the incidence of anti-rHuPH20 antibodies was 5.4% (12/224) and the incidence of NAb was 0% (0/12). Because of the low occurrence of anti-rHuPH20 antibodies, the effect of these antibodies on the pharmacokinetics, pharmacodynamics and/or safety of hyaluronidase in TECENTRIQ HYBREZA is unknown. Immunogenicity with Other Clinical Trials with Intravenous Atezolizumab: During the first year of treatment with intravenous atezolizumab across clinical studies of patients with NSCLC, SCLC, HCC, and melanoma 13% to 36% of patients developed anti-atezolizumab antibodies. Across clinical studies, the NAb incidence in ADA-positive patients was 24% to 83%. In OAK and IMbrave150, exploratory analyses showed that the subset of patients who were ADA-positive appeared to have less efficacy (effect on overall survival) as compared to patients who tested negative for ADA [see Clinical Studies (14.1 , 14.3) ] . In study IMpower150, the impact of ADA on efficacy did not appear to be clinically significant [see Clinical Studies (14.1) ] . In the remaining studies, there is insufficient information to characterize the effect of ADA on efficacy. Median atezolizumab clearance in patients who tested positive for anti-atezolizumab antibodies (ADA) was 19% (range of 18% to 49%) higher as compared to atezolizumab clearance in patients who tested negative for ADA; this change in clearance is not expected to be clinically significant. The presence of ADA did not have a clinically significant effect on the incidence or severity of adverse reactions. The effect of NAb on atezolizumab exposure and safety did not appear to be clinically significant. The effect of NAb on key efficacy endpoints is uncertain due to small sample sizes.

13.2 Animal Toxicology and/or Pharmacology In animal models, inhibition of PD-L1/PD-1 signaling increased the severity of some infections and enhanced inflammatory responses. Mycobacterium tuberculosis-infected PD-1 knockout mice exhibit markedly decreased survival compared with wild-type controls, which correlated with increased bacterial proliferation and inflammatory responses in these animals. PD-L1 and PD-1 knockout mice and mice receiving PD-L1 blocking antibody have also shown decreased survival following infection with lymphocytic choriomeningitis virus.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility No studies have been performed to test the potential of atezolizumab for carcinogenicity or genotoxicity. Animal fertility studies have not been conducted with atezolizumab; however, an assessment of the male and female reproductive organs was included in a 26-week, repeat-dose toxicity study in cynomolgus monkeys. Weekly administration of atezolizumab to female monkeys at the highest dose tested caused an irregular menstrual cycle pattern and a lack of newly formed corpora lutea in the ovaries. This effect occurred at an estimated AUC approximately 6 times the AUC in patients receiving the recommended intravenous atezolizumab dose and was reversible. There was no effect on the male monkey reproductive organs. Hyaluronidases are found in most tissues of the body. Long-term animal studies have not been performed to assess the carcinogenic or mutagenic potential of hyaluronidase. In addition, when up to 220,000 units/kg of subcutaneous hyaluronidase (recombinant human) was administered to cynomolgus monkeys for 39 weeks, which is > 223 times higher than the human recommended dose for hyaluronidase, no evidence of toxicity to the male or female reproductive system was found through periodic monitoring of in-life parameters (e.g., semen analyses, hormone levels, menstrual cycles, and also from gross pathology, histopathology and organ weight data).

TECENTRIQ HYBREZA is a prescription medicine used to treat adults with: a type of lung cancer called non-small cell lung cancer (NSCLC). TECENTRIQ HYBREZA may be used alone as a treatment for your lung cancer: to help prevent your lung cancer from coming back after your tumor(s) has been removed by surgery and you have received platinum-based chemotherapy, and you have stage 2 to stage 3A NSCLC (talk to your healthcare provider about what these stages mean), and your cancer tests positive for "PD-L1." TECENTRIQ HYBREZA may be used alone as your first treatment when your lung cancer: has spread or grown, and your cancer tests positive for "high PD-L1," and your tumor does not have an abnormal "EGFR" or "ALK" gene. TECENTRIQ HYBREZA may be used with the medicines bevacizumab, paclitaxel, and carboplatin as your first treatment when your lung cancer: has spread or grown, and is a type called "non-squamous NSCLC," and your tumor does not have an abnormal "EGFR" or "ALK" gene. TECENTRIQ HYBREZA may be used with the medicines paclitaxel protein-bound and carboplatin as your first treatment when your lung cancer: has spread or grown, and is a type called "non-squamous NSCLC," and your tumor does not have an abnormal "EGFR" or "ALK" gene. TECENTRIQ HYBREZA may also be used alone when your lung cancer: has spread or grown, and you have tried chemotherapy that contains platinum, and it did not work or is no longer working. if your tumor has an abnormal "EGFR" or "ALK" gene, you should have also tried an FDA-approved therapy for tumors with these abnormal genes, and it did not work or is no longer working. a type of lung cancer called small cell lung cancer (SCLC). TECENTRIQ HYBREZA may be used with the chemotherapy medicines carboplatin and etoposide as your first treatment when your lung cancer is a type called "extensive-stage SCLC," which means that it has spread or grown. a type of liver cancer called hepatocellular carcinoma (HCC). TECENTRIQ HYBREZA may be used with the medicine bevacizumab when your liver cancer: has spread or cannot be removed by surgery, and you have not received other medicines by mouth or injection through your vein (IV) to treat your cancer. a type of skin cancer called melanoma. TECENTRIQ HYBREZA may be used with the medicines cobimetinib and vemurafenib when your melanoma: has spread to other parts of the body or cannot be removed by surgery, and has a certain type of abnormal "BRAF" gene. Your healthcare provider will perform a test to make sure this TECENTRIQ HYBREZA combination is right for you. a type of soft tissue tumor (cancer) called alveolar soft part sarcoma (ASPS).

14 CLINICAL STUDIES 14.1 Non-Small Cell Lung Cancer NSCLC - TECENTRIQ HYBREZA IMscin001 (NCT03735121) was an open-label, multi-center, international, randomized study conducted in adult patients with locally advanced or metastatic NSCLC who were not exposed to cancer immunotherapy and who have disease progression following platinum-based chemotherapy. Patients were excluded if they had a history of autoimmune disease; active or corticosteroid-dependent brain metastases; received a live, attenuated vaccine within 4 weeks prior to randomization; or received systemic immunostimulatory agents within 4 weeks or systemic immunosuppressive drugs within 2 weeks prior to randomization. A total of 371 patients were randomized 2:1 to receive either TECENTRIQ HYBREZA (containing 1,875 mg of atezolizumab and 30,000 units of hyaluronidase) administered subcutaneously in the thigh every 3 weeks (n = 247) or intravenous atezolizumab 1,200 mg every 3 weeks (n = 124) until disease progression or unacceptable toxicity. The primary outcome measure was atezolizumab exposure (C trough and AUC 0-21days ) of subcutaneous TECENTRIQ HYBREZA as compared to intravenous atezolizumab [see Clinical Pharmacology (12.3) ] . Additional descriptive efficacy outcome measures were overall response rate (ORR), progression-free survival (PFS) and overall survival (OS). The median age was 64 years (range: 27 to 85); 69% were male; 67% were White, 22% were Asian, and 0.8% were Black or African American; 74% were non-Hispanic or Latino; 26% had an Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0, 74% had an ECOG PS of 1; and 70% of patients were current or previous smokers. Sixty-five percent of patients had non-squamous histology, 5% had known EGFR mutations, 1.6% had known ALK rearrangements, 36% had known PD-L1 positive tumors, 16% had asymptomatic CNS metastases at baseline. Eighty percent of patients had received only one prior therapeutic regimen for NSCLC. At the primary analysis, the confirmed ORR was 9% (95% CI: 5, 13) in the subcutaneous TECENTRIQ HYBREZA arm and 8% (95% CI: 4, 14) in the intravenous atezolizumab arm. After further follow up, no notable differences in PFS and OS were observed between patients who received subcutaneous TECENTRIQ HYBREZA and patients who received intravenous atezolizumab. NSCLC Trials - Intravenous Atezolizumab The effectiveness of TECENTRIQ HYBREZA has been established for: adjuvant treatment (following tumor resection and platinum-based chemotherapy) in adult patients with stage II to IIIA NSCLC whose tumors have PD-L1 expression on ≥ 1% of tumor cells (IMpower010 study). first-line treatment of adult patients with metastatic NSCLC whose tumors have high PD-L1 expression (PD-L1 stained ≥ 50% of tumor cells [TC ≥ 50%] or PD-L1 stained tumor-infiltrating immune cells [IC] covering ≥ 10% of the tumor area [IC ≥ 10%]), with no EGFR or ALK genomic tumor aberrations (IMpower110 study). first-line treatment of adult patients with metastatic non-squamous NSCLC with no EGFR or ALK genomic tumor aberrations (IMpower150 study). first-line treatment of adult patients with metastatic non-squamous NSCLC with no EGFR or ALK genomic tumor aberrations (IMpower130 study). first-line treatment of adult patients with metastatic NSCLC whose tumors have high PD-L1 expression, with no EGFR or ALK genomic tumor aberrations (OAK study). Use of TECENTRIQ HYBREZA for these NSCLC indications is supported by evidence from the adequate and well-controlled studies conducted with intravenous atezolizumab in these NSCLC populations and pharmacokinetics data that demonstrated comparable exposures to atezolizumab between TECENTRIQ HYBREZA and intravenous atezolizumab in the IMscin001 trial [see Adverse Reactions (6.1) , Clinical Pharmacology (12.3) , and Clinical Studies (14.1) ]. Below is a description of the efficacy results of these adequate and well-controlled studies of intravenous atezolizumab in these NSCLC populations. Adjuvant Treatment of Early-stage NSCLC IMpower010 The efficacy of intravenous atezolizumab was evaluated in IMpower010 (NCT02486718), a multi-center, randomized, open-label trial for the adjuvant treatment of patients with NSCLC who had complete tumor resection and were eligible to receive cisplatin-based adjuvant chemotherapy. Eligible patients were required to have Stage IB (tumors ≥ 4 cm) – Stage IIIA NSCLC per the Union for International Cancer Control/American Joint Committee on Cancer staging system, 7th edition. Patients were excluded if they had a history of autoimmune disease; a history of idiopathic pulmonary fibrosis, organizing pneumonia, drug-induced pneumonitis, idiopathic pneumonitis, or evidence of active pneumonitis; administration of a live, attenuated vaccine within 28 days prior to randomization; administration of systemic immunostimulatory agents within 4 weeks or systemic immunosuppressive medications within 2 weeks prior to randomization. A total of 1005 patients who had complete tumor resection and received cisplatin-based adjuvant chemotherapy were randomized (1:1) to receive intravenous atezolizumab 1200 mg intravenous infusion every 3 weeks for 16 cycles, unless disease recurrence or unacceptable toxicity occurred, or best supportive care (BSC). Randomization was stratified by sex, stage of disease, histology, and PD-L1 expression. Tumor assessments were conducted at baseline of the randomization phase and every 4 months for the first year following Cycle 1, Day 1 and then every 6 months until year five, then annually thereafter. The median age was 62 years (range: 26 to 84), and 67% of patients were male. The majority of patients were White (73%) and Asian (24%). Most patients were current or previous smokers (78%) and baseline ECOG performance status in patients was 0 (55%) or 1 (44%). Overall, 12% of patients had Stage IB, 47% had Stage II and 41% had Stage IIIA disease. PD-L1 expression, defined as the percentage of tumor cells expressing PD-L1 as measured by the VENTANA PD-L1 (SP263) assay, was ≥ 1% in 53% of patients, < 1% in 44% and unknown in 2.6%. The primary efficacy outcome measure was disease-free survival (DFS) as assessed by the investigator. The primary efficacy analysis population (n = 476) was patients with Stage II – IIIA NSCLC with PD-L1 expression on ≥ 1% of tumor cells (PD-L1 ≥ 1% TC). DFS was defined as the time from the date of randomization to the date of occurrence of any of the following: first documented recurrence of disease, new primary NSCLC, or death due to any cause, whichever occurred first. A key secondary efficacy outcome measure was overall survival (OS) in the intent-to-treat population. At the time of the interim DFS analysis, the study demonstrated a statistically significant improvement in DFS in the PD-L1 ≥ 1% TC, Stage II – IIIA patient population. Efficacy results are presented in Table 23 and Figure 1 . Table 23: Efficacy Results from IMpower010 in Patients with Stage II - IIIA NSCLC with PD-L1 expression ≥ 1% TC Arm A: Intravenous Atezolizumab N = 248 Arm B: Best Supportive Care N = 228 CI = Confidence interval, NE = Not estimable, NR = Not reached Disease-Free Survival Number of events (%) 88 (35) 105 (46) Median, months NR 35.3 (95% CI) (36.1, NE) (29.0, NE) Hazard ratio Stratified by stage, sex, and histology (95% CI) 0.66 (0.50, 0.88) p-value 0.004 In a pre-specified secondary subgroup analysis of patients with PD-L1 TC ≥ 50% Stage II – IIIA NSCLC (n = 229), the median DFS was not reached (95% CI: 42.3 months, NE) for patients in the intravenous atezolizumab arm and was 35.7 months (95% CI: 29.7, NE) for patients in the best supportive care arm, with a HR of 0.43 (95% CI: 0.27, 0.68). In an exploratory subgroup analysis of patients with PD-L1 TC 1-49% Stage II – IIIA NSCLC (n = 247), the median DFS was 32.8 months (95% CI:29.4, NE) for patients in the intravenous atezolizumab arm and 31.4 months (95% CI: 24.0, NE) for patients in the best supportive care arm, with a HR of 0.87 (95% CI: 0.60, 1.26). Figure 1: Kaplan-Meier Plot of Disease-Free Survival in IMpower010 in Patients with Stage II – IIIA NSCLC with PD-L1 expression ≥ 1% TC At the time of the DFS interim analysis, 19% of patients in the PD-L1 ≥1% TC Stage II – IIIA patient population had died. An exploratory analysis of OS in this population resulted in a stratified HR of 0.77 (95% CI: 0.51, 1.17). Metastatic Chemotherapy-Naïve NSCLC IMpower110 The efficacy of intravenous atezolizumab was evaluated in IMpower110 (NCT02409342), a multicenter, international, randomized, open-label trial in patients with stage IV NSCLC whose tumors express PD-L1 (PD-L1 stained ≥ 1% of tumor cells [TC ≥ 1%] or PD-L1 stained tumor-infiltrating immune cells [IC] covering ≥ 1% of the tumor area [IC ≥ 1%]), who had received no prior chemotherapy for metastatic disease. PD-L1 tumor status was determined based on immunohistochemistry (IHC) testing using the VENTANA PD-L1 (SP142) Assay. The evaluation of efficacy is based on the subgroup of patients with high PD-L1 expression (TC ≥ 50% or IC ≥ 10%), excluding those with EGFR or ALK genomic tumor aberrations. The trial excluded patients with a history of autoimmune disease, administration of a live attenuated vaccine within 28 days prior to randomization, active or untreated CNS metastases, administration of systemic immunostimulatory agents within 4 weeks or systemic immunosuppressive medications within 2 weeks prior to randomization. Randomization was stratified by sex, ECOG performance status, histology (non-squamous vs. squamous) and PD-L1 expression (TC ≥ 1% and any IC vs. TC < 1% and IC ≥ 1%). Patients were randomized (1:1) to receive one of the following treatment arms: Arm A: Intravenous atezolizumab 1200 mg every 3 weeks until disease progression or unacceptable toxicity Arm B: Platinum-based chemotherapy Arm B platinum-based chemotherapy regimens for non-squamous NSCLC consisted of cisplatin (75 mg/m²) and pemetrexed (500 mg/m²) OR carboplatin (AUC 6 mg/mL/min) and pemetrexed (500 mg/m²) on Day 1 of each 21-day cycle for a maximum of 4 or 6 cycles followed by pemetrexed (500 mg/m²) until disease progression or unacceptable toxicity. Arm B platinum-based chemotherapy regimens for squamous NSCLC consisted of cisplatin (75 mg/m²) on Day 1 with gemcitabine (1250 mg/m2) on Days 1 and 8 of each 21-day cycle OR carboplatin (AUC 5 mg/mL/min) on Day 1 with gemcitabine (1000 mg/m 2 ) on Days 1 and 8 of each 21-day cycle for a maximum of 4 or 6 cycles followed by best supportive care until disease progression or unacceptable toxicity. Administration of intravenous atezolizumab was permitted beyond RECIST-defined disease progression. Tumor assessments were conducted every 6 weeks for the first 48 weeks following Cycle 1, Day 1 and then every 9 weeks thereafter. Tumor specimens were evaluated prospectively using the VENTANA PD-L1 (SP142) Assay at a central laboratory and the results were used to define subgroups for pre-specified analyses. The major efficacy outcome measure was overall survival (OS) sequentially tested in the following subgroups of patients, excluding those with EGFR or ALK genomic tumor aberrations: TC ≥ 50% or IC ≥ 10%; TC ≥ 5% or IC ≥ 5%; and TC ≥ 1% or IC ≥ 1%. Among the 205 chemotherapy-naïve patients with stage IV NSCLC with high PD-L1 expression (TC ≥ 50% or IC ≥ 10%) excluding those with EGFR or ALK genomic tumor aberrations, the median age was 65.0 years (range: 33 to 87), and 70% of patients were male. The majority of patients were White (82%) and Asian (17%). Baseline ECOG performance status was 0 (36%) or 1 (64%); 88% were current or previous smokers; and 76% of patients had non-squamous disease while 24% of patients had squamous disease. The trial demonstrated a statistically significant improvement in OS for patients with high PD-L1 expression (TC ≥ 50% or IC ≥ 10%) at the time of the OS interim analysis. There was no statistically significant difference in OS for the other two PD-L1 subgroups (TC ≥ 5% or IC ≥ 5%; and TC ≥ 1% or IC ≥ 1%) at the interim or final analyses. Efficacy results for patients with NSCLC with high PD-L1 expression are presented in Table 24 and Figure 2 . Table 24: Efficacy Results from IMpower110 in Patients with NSCLC with High PD-L1 Expression (TC ≥ 50% or IC ≥ 10%) and without EGFR or ALK Genomic Tumor Aberrations Arm A: Intravenous Atezolizumab Arm B: Platinum-Based Chemotherapy N = 107 N = 98 CI = confidence interval; NE = not estimable Overall Survival Based on OS interim analysis.

The investigator-assessed confirmed ORR was 38% (95% CI: 29%, 48%) in the intravenous atezolizumab arm and 29% (95% CI: 20%, 39%) in the platinum-based chemotherapy arm. First-Line Metastatic Non-squamous NSCLC IMpower150 The efficacy of intravenous atezolizumab with bevacizumab, paclitaxel, and carboplatin was evaluated in IMpower150 (NCT02366143), a multicenter, international, randomized (1:1:1), open-label trial in patients with metastatic non-squamous NSCLC. Patients with stage IV non-squamous NSCLC who had received no prior chemotherapy for metastatic disease but could have received prior EGFR or ALK kinase inhibitor if appropriate, regardless of PD-L1 or T-effector gene (tGE) status and ECOG performance status 0 or 1 were eligible. The trial excluded patients with a history of autoimmune disease, administration of a live attenuated vaccine within 28 days prior to randomization, active or untreated CNS metastases, administration of systemic immunostimulatory agents within 4 weeks or systemic immunosuppressive medications within 2 weeks prior to randomization, or clear tumor infiltration into the thoracic great vessels or clear cavitation of pulmonary lesions as seen on imaging. Randomization was stratified by sex, presence of liver metastases, and PD-L1 expression status on tumor cells (TC) and tumor-infiltrating immune cells (IC) as follows: TC3 and any IC vs. TC0/1/2 and IC2/3 vs. TC0/1/2 and IC0/1. Patients were randomized to one of the following three treatment arms: Arm A: intravenous atezolizumab 1200 mg, paclitaxel 175 mg/m² or 200 mg/m² and carboplatin AUC 6 mg/mL/min on Day 1 of each 21-day cycle for a maximum of 4 or 6 cycles Arm B: intravenous atezolizumab 1200 mg, bevacizumab 15 mg/kg, paclitaxel 175 mg/m² or 200 mg/m², and carboplatin AUC 6 mg/mL/min on Day 1 of each 21-day cycle for a maximum of 4 or 6 cycles Arm C: bevacizumab 15 mg/kg, paclitaxel 175 mg/m² or 200 mg/m², and carboplatin AUC 6 mg/mL/min on Day 1 of each 21-day cycle for a maximum of 4 or 6 cycles Patients who had not experienced disease progression following the completion or cessation of platinum-based chemotherapy, received: Arm A: intravenous atezolizumab 1200 mg intravenously on Day 1 of each 21-day cycle until disease progression or unacceptable toxicity Arm B: intravenous atezolizumab 1200 mg and bevacizumab 15 mg/kg intravenously on Day 1 of each 21-day cycle until disease progression or unacceptable toxicity Arm C: bevacizumab 15 mg/kg intravenously on Day 1 of each 21-day cycle until disease progression or unacceptable toxicity Tumor assessments were conducted every 6 weeks for the first 48 weeks following Cycle 1, Day 1 and then every 9 weeks thereafter. Tumor specimens were evaluated prior to randomization for PD-L1 tumor expression using the VENTANA PD-L1 (SP142) assay at a central laboratory. Tumor tissue was collected at baseline for expression of tGE signature and evaluation was performed using a clinical trial assay in a central laboratory prior to the analysis of efficacy outcome measures. Major efficacy outcome measures for comparison of Arms B and C were progression free survival (PFS) by RECIST v1.1 in the tGE-WT (patients with high expression of T-effector gene signature [tGE], excluding those with EGFR- and ALK-positive NSCLC [WT]) and in the ITT-WT subpopulations and overall survival (OS) in the ITT-WT subpopulation. Additional efficacy outcome measures for comparison of Arms B and C or Arms A and C were PFS and OS in the ITT population, OS in the tGE-WT subpopulation, and ORR/DoR in the tGE-WT and ITT-WT subpopulations. A total of 1202 patients were enrolled across the three arms of whom 1045 were in the ITT-WT subpopulation and 447 were in the tGE-WT subpopulation. The demographic information is limited to the 800 patients enrolled in Arms B and C where efficacy has been demonstrated. The median age was 63 years (range: 31 to 90), and 60% of patients were male. The majority of patients were White (82%), 13% of patients were Asian, 10% were Hispanic, and 2% of patients were Black. Clinical sites in Asia (enrolling 13% of the study population) received paclitaxel at a dose of 175 mg/m2 while the remaining 87% received paclitaxel at a dose of 200 mg/m2. Approximately 14% of patients had liver metastases at baseline, and most patients were current or previous smokers (80%). Baseline ECOG performance status was 0 (43%) or 1 (57%). PD-L1 was TC3 and any IC in 12%, TC0/1/2 and IC2/3 in 13%, and TC0/1/2 and IC0/1 in 75%. The demographics for the 696 patients in the ITT-WT subpopulation were similar to the ITT population except for the absence of patients with EGFR- or ALK-positive NSCLC. The trial demonstrated a statistically significant improvement in PFS between Arms B and C in both the tGE-WT and ITT-WT subpopulations, but did not demonstrate a significant difference for either subpopulation between Arms A and C based on the final PFS analyses. In the interim analysis of OS, a statistically significant improvement was observed for Arm B compared to Arm C, but not for Arm A compared to Arm C. Efficacy results for the ITT-WT subpopulation are presented in Table 25 and Figure 3 . Table 25: Efficacy Results in ITT-WT Population in IMpower150 Arm C: Bevacizumab, Paclitaxel and Carboplatin Arm B: Intravenous Atezolizumab with Bevacizumab, Paclitaxel, and Carboplatin Arm A: Intravenous Atezolizumab with Paclitaxel, and Carboplatin N = 337 N = 359 N = 349 CI = confidence interval Overall Survival Based on OS interim analysis Deaths (%) 197 (59%) 179 (50%) 179 (51%) Median, months 14.7 19.2 19.4 (95% CI) (13.3, 16.9) (17.0, 23.8) (15.7, 21.3) Hazard ratio Stratified by sex, presence of liver metastases, and PD-L1 expression status on TC and IC (95% CI) --- 0.78 (0.64, 0.96) 0.84 (0.72, 1.08) p-value Based on the stratified log-rank test compared to Arm C --- 0.016 Compared to the allocated α=0.0174 (two sided) for this interim analysis 0.204 Compared to the allocated α=0.0128 (two sided) for this interim analysis Progression-Free Survival As determined by independent review facility (IRF) per RECIST v1.1 (Response Evaluation Criteria in Solid Tumors v1.1) Number of events (%) 247 (73%) 247 (69%) 245 (70%) Median, months 7.0 8.5 6.7 (95% CI) (6.3, 7.9) (7.3, 9.7) (5.6, 6.9) Hazard ratio (95% CI) --- 0.71 (0.59, 0.85) 0.94 (0.79, 1.13) p-value --- 0.0002 Compared to the allocated α=0.006 (two sided) for the final PFS analysis 0.5219 Objective Response Rate Number of responders (%) 142 (42%) 196 (55%) 150 (43%) (95% CI) (37, 48) (49, 60) (38, 48) Complete Response 3 (1%) 14 (4%) 9 (3%) Partial Response 139 (41%) 182 (51%) 141 (40%) Duration of Response n = 142 n = 196 n = 150 Median, months 6.5 10.8 9.5 (95% CI) (5.6, 7.6) (8.4, 13.9) (7.0, 13.0) Figure 3: Kaplan-Meier Curves for Overall Survival in ITT-WT Population in IMpower150 Exploratory analyses showed that the subset of patients in the four drug regimen arm who were ADA positive by week 4 (30%) appeared to have similar efficacy (effect on overall survival) as compared to patients who tested negative for treatment-emergent ADA by week 4 (70%) [see, Clinical Pharmacology (12.6) ] . In an exploratory analysis, propensity score matching was conducted to compare ADA positive patients in the intravenous atezolizumab, bevacizumab, paclitaxel, and carboplatin arm with a matched population in the bevacizumab, paclitaxel, and carboplatin arm. Similarly, ADA negative patients in the intravenous atezolizumab, bevacizumab, paclitaxel, and carboplatin arm were compared with a matched population in the bevacizumab, paclitaxel, and carboplatin arm. Propensity score matching factors were: baseline sum of longest tumor size (BSLD), baseline ECOG, baseline albumin, baseline LDH, sex, tobacco history, metastatic site, TC level, and IC level. The hazard ratio comparing the ADA-positive subgroup with its matched control was 0.69 (95% CI: 0.44, 1.07). The hazard ratio comparing the ADA-negative subgroup with its matched control was 0.64 (95% CI: 0.46, 0.90). IMpower130 The efficacy of intravenous atezolizumab with paclitaxel protein-bound and carboplatin was evaluated in IMpower130 (NCT02367781), a multicenter, randomized (2:1), open-label trial in patients with stage IV non-squamous NSCLC. Patients with Stage IV non-squamous NSCLC who had received no prior chemotherapy for metastatic disease, but could have received prior EGFR or ALK kinase inhibitor, if appropriate, were eligible. The trial excluded patients with history of autoimmune disease, administration of live attenuated vaccine within 28 days prior to randomization, administration of immunostimulatory agents within 4 weeks or systemic immunosuppressive medications within 2 weeks prior to randomization, and active or untreated CNS metastases. Randomization was stratified by sex, presence of liver metastases, and PD-L1 tumor expression according to the VENTANA PD-L1 (SP142) assay as follows: TC3 and any IC vs. TC0/1/2 and IC2/3 vs. TC0/1/2 and IC0/1. Patients were randomized to one of the following treatment regimens: Intravenous atezolizumab 1200 mg on Day 1, paclitaxel protein-bound 100 mg/m² on Days 1, 8, and 15, and carboplatin AUC 6 mg/mL/min on Day 1 of each 21-day cycle for a maximum of 4 or 6 cycles followed by intravenous atezolizumab 1200 mg once every 3 weeks until disease progression or unacceptable toxicity, or Paclitaxel protein-bound 100 mg/m² on Days 1, 8 and 15 and carboplatin AUC 6 mg/mL/min on Day 1 of each 21-day cycle for a maximum of 4 or 6 cycles followed by best supportive care or pemetrexed. Tumor assessments were conducted every 6 weeks for the first 48 weeks, then every 9 weeks thereafter. Major efficacy outcome measures were PFS by RECIST v1.1 and OS in the subpopulation of patients evaluated for and documented to have no EGFR or ALK genomic tumor aberrations (ITT-WT). A total of 724 patients were enrolled; of these, 681 (94%) were in the ITT-WT population. The median age was 64 years (range: 18 to 86) and 59% were male. The majority of patients were White (90%), 2% of patients were Asian, 5% were Hispanic, and 4% were Black. Baseline ECOG performance status was 0 (41%) or 1 (58%). Most patients were current or previous smokers (90%). PD-L1 tumor expression was TC0/1/2 and IC0/1 in 73%; TC3 and any IC in 14%; and TC0/1/2 and IC2/3 in 13%. Efficacy results for the ITT-WT population are presented in Table 26 and Figure 4 .

Patients with a history of autoimmune disease, symptomatic or corticosteroid-dependent brain metastases, or requiring systemic immunosuppression within 2 weeks prior to enrollment were ineligible. Randomization was stratified by PD-L1 expression tumor-infiltrating immune cells (IC), the number of prior chemotherapy regimens (1 vs. 2), and histology (squamous vs. non-squamous). Patients were randomized to receive intravenous atezolizumab 1200 mg intravenously every 3 weeks until unacceptable toxicity, radiographic progression, or clinical progression or docetaxel 75 mg/m 2 intravenously every 3 weeks until unacceptable toxicity or disease progression. Tumor assessments were conducted every 6 weeks for the first 36 weeks and every 9 weeks thereafter. Major efficacy outcome measure was overall survival (OS) in the first 850 randomized patients and OS in the subgroup of patients with PD-L1-expressing tumors (defined as ≥ 1% PD-L1 expression on tumor cells [TC] or immune cells [IC]). Additional efficacy outcome measures were OS in all randomized patients (n = 1225), OS in subgroups based on PD-L1 expression, overall response rate (ORR), and progression free survival as assessed by the investigator per RECIST v.1.1. Among the first 850 randomized patients, the median age was 64 years (33 to 85 years) and 47% were ≥ 65 years old; 61% were male; 70% were White and 21% were Asian; 15% were current smokers and 67% were former smokers; and 37% had baseline ECOG PS of 0 and 63% had a baseline ECOG PS of 1. Nearly all (94%) had metastatic disease, 74% had non-squamous histology, 75% had received only one prior platinum-based chemotherapy regimen, and 55% of patients had PD-L1-expressing tumors. Efficacy results are presented in Table 27 and Figure 5 Table 27: Efficacy Results in OAK Intravenous Atezolizumab Docetaxel CI = confidence interval; NE = not estimable Overall Survival in first 850 patients Number of patients N = 425 N = 425 Deaths (%) 271 (64%) 298 (70%) Median, months 13.8 9.6 (95% CI) (11.8, 15.7) (8.6, 11.2) Hazard ratio Stratified by PD-L1 expression in tumor infiltrating immune cells, the number of prior chemotherapy regimens, and histology (95% CI) 0.74 (0.63, 0.87) p-value Based on the stratified log-rank test 0.0004 Compared to the pre-specified allocated α of 0.03 for this analysis Progression-Free Survival Number of Patients N = 425 N = 425 Events (%) 380 (89%) 375 (88%) Progression (%) 332 (78%) 290 (68%) Deaths (%) 48 (11%) 85 (20%) Median, months 2.8 4.0 (95% CI) (2.6, 3.0) (3.3, 4.2) Hazard ratio (95% CI) 0.95 (0.82, 1.10) Overall Response Rate Per RECIST v1.1 (Response Evaluation Criteria in Solid Tumors v1.1) Number of Patients N = 425 N = 425 ORR, n (%) 58 (14%) 57 (13%) (95% CI) (11%, 17%) (10%, 17%) Complete Response 6 (1%) 1 (0.2%) Partial Response 52 (12%) 56 (13%) Duration of Response N = 58 N = 57 Median, months 16.3 6.2 (95% CI) (10.0, NE) (4.9, 7.6) Overall Survival in all 1225 patients Number of patients N = 613 N = 612 Deaths (%) 384 (63%) 409 (67%) Median, months 13.3 9.8 (95% CI) (11.3, 14.9) (8.9, 11.3) Hazard ratio (95% CI) 0.79 (0.69, 0.91) p-value 0.0013 Compared to the allocated α of 0.0177 for this interim analysis based on 86% information using O'Brien-Fleming boundary Figure 5: Kaplan-Meier Curves of Overall Survival in the First 850 Patients Randomized in OAK Tumor specimens were evaluated prospectively using the VENTANA PD-L1 (SP142) Assay at a central laboratory and the results were used to define the PD-L1 expression subgroups for pre-specified analyses. Of the 850 patients, 16% were classified as having high PD-L1 expression, defined as having PD-L1 expression on ≥ 50% of TC or ≥ 10% of IC. In an exploratory efficacy subgroup analysis of OS based on PD-L1 expression, the hazard ratio was 0.41 (95% CI: 0.27, 0.64) in the high PD-L1 expression subgroup and 0.82 (95% CI: 0.68, 0.98) in patients who did not have high PD-L1 expression. Exploratory analyses showed that the subset of patients who were ADA positive by week 4 (21%) appeared to have less efficacy (effect on overall survival) as compared to patients who tested negative for treatment-emergent ADA by week 4 (79%) [see Clinical Pharmacology (12.6) ]. ADA positive patients by week 4 appeared to have similar OS compared to docetaxel-treated patients. In an exploratory analysis, propensity score matching was conducted to compare ADA positive patients in the atezolizumab arm with a matched population in the docetaxel arm and ADA negative patients in the atezolizumab arm with a matched population in the docetaxel arm. Propensity score matching factors were: baseline sum of longest tumor size (BSLD), baseline ECOG, histology (squamous vs. non-squamous), baseline albumin, baseline LDH, gender, tobacco history, metastases status (advanced or local), metastatic site, TC level, and IC level. The hazard ratio comparing the ADA positive subgroup with its matched control was 0.89 (95% CI: 0.61, 1.3). The hazard ratio comparing the ADA negative subgroup with its matched control was 0.68 (95% CI: 0.55, 0.83). Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 14.2 Small Cell Lung Cancer The efficacy of TECENTRIQ HYBREZA in combination with carboplatin and etoposide for the first-line treatment of adult patients with extensive-stage small cell lung cancer (ES-SCLC) has been established in adequate and well-controlled studies of intravenous atezolizumab in combination with carboplatin and etoposide for ES-SCLC. Below is a description of adverse reactions of intravenous atezolizumab in combination with carboplatin and etoposide in this adequate and well-controlled ES-SCLC trial. Small Cell Lung Cancer (SCLC) IMpower133 The efficacy of intravenous atezolizumab with carboplatin and etoposide was investigated in IMpower133 (NCT02763579), a randomized (1:1), multicenter, double-blind, placebo-controlled trial in 403 patients with ES-SCLC. IMpower133 enrolled patients with ES-SCLC who had received no prior chemotherapy for extensive stage disease and ECOG performance status 0 or 1. The trial excluded patients with active or untreated CNS metastases, history of autoimmune disease, administration of a live, attenuated vaccine within 4 weeks prior to randomization, or administration of systemic immunosuppressive medications within 1 week prior to randomization. Randomization was stratified by sex, ECOG performance status, and presence of brain metastases. Patients were randomized to receive one of the following two treatment arms: intravenous atezolizumab 1200 mg and carboplatin AUC 5 mg/mL/min on Day 1 and etoposide 100 mg/m 2 intravenously on Days 1, 2 and 3 of each 21-day cycle for a maximum of 4 cycles followed by intravenous atezolizumab 1200 mg once every 3 weeks until disease progression or unacceptable toxicity, or placebo and carboplatin AUC 5 mg/mL/min on Day 1 and etoposide 100 mg/m 2 intravenously on Days 1, 2, and 3 of each 21-day cycle for a maximum of 4 cycles followed by placebo once every 3 weeks until disease progression or unacceptable toxicity. Administration of intravenous atezolizumab was permitted beyond RECIST-defined disease progression. Tumor assessments were conducted every 6 weeks for the first 48 weeks following Cycle 1, Day 1 and then every 9 weeks thereafter. Patients treated beyond disease progression had tumor assessment conducted every 6 weeks until treatment discontinuation. Major efficacy outcome measures were OS and PFS as assessed by investigator per RECIST v1.1 in the intent-to-treat population. Additional efficacy outcome measures included ORR and DoR as assessed by investigator per RECIST v1.1. A total of 403 patients were randomized, including 201 to the intravenous atezolizumab arm and 202 to the chemotherapy alone arm. The median age was 64 years (range: 26 to 90) and 65% were male. The majority of patients were White (80%); 17% were Asian, 4% were Hispanic and 1% were Black. Baseline ECOG performance status was 0 (35%) or 1 (65%); 9% of patients had a history of brain metastases, and 97% were current or previous smokers. Efficacy results are presented in Table 28 and Figure 6 .

Below is a description of efficacy reactions of intravenous atezolizumab in combination with bevacizumab in this adequate and well-controlled HCC trial. Hepatocellular Carcinoma IMbrave150 The efficacy of intravenous atezolizumab in combination with bevacizumab was investigated in IMbrave150 (NCT03434379), a multicenter, international, open-label, randomized trial in patients with locally advanced unresectable and/or metastatic hepatocellular carcinoma who have not received prior systemic therapy. Randomization was stratified by geographic region (Asia excluding Japan vs. rest of world), macrovascular invasion and/or extrahepatic spread (presence vs. absence), baseline AFP (< 400 vs. ≥ 400 ng/mL), and by ECOG performance status (0 vs. 1). A total of 501 patients were randomized (2:1) to receive either intravenous atezolizumab as an intravenous infusion of 1200 mg, followed by 15 mg/kg bevacizumab, on the same day every 3 weeks or sorafenib 400 mg given orally twice daily, until disease progression or unacceptable toxicity. Patients could discontinue either intravenous atezolizumab or bevacizumab (e.g., due to adverse events) and continue on monotherapy until disease progression or unacceptable toxicity associated with the monotherapy. The study enrolled patients who were ECOG performance score 0 or 1 and who had not received prior systemic treatment. Patients were required to be evaluated for the presence of varices within 6 months prior to treatment, and were excluded if they had variceal bleeding within 6 months prior to treatment, untreated or incompletely treated varices with bleeding, or high risk of bleeding. Patients with Child-Pugh B or C cirrhosis, moderate or severe ascites; history of hepatic encephalopathy; a history of autoimmune disease; administration of a live, attenuated vaccine within 4 weeks prior to randomization; administration of systemic immunostimulatory agents within 4 weeks or systemic immunosuppressive medications within 2 weeks prior to randomization; or untreated or corticosteroid-dependent brain metastases were excluded. Tumor assessments were performed every 6 weeks for the first 54 weeks and every 9 weeks thereafter. The demographics and baseline disease characteristics of the study population were balanced between the treatment arms. The median age was 65 years (range: 26 to 88) and 83% of patients were male. The majority of patients were Asian (57%) or White (35%); 40% were from Asia (excluding Japan). Approximately 75% of patients presented with macrovascular invasion and/or extrahepatic spread and 37% had a baseline AFP ≥ 400 ng/mL. Baseline ECOG performance status was 0 (62%) or 1 (38%). HCC risk factors were Hepatitis B in 48% of patients, Hepatitis C in 22%, and 31% of patients had non-viral liver disease. The majority of patients had BCLC stage C (82%) disease at baseline, while 16% had stage B, and 3% had stage A. The major efficacy outcome measures were overall survival (OS) and independent review facility (IRF)-assessed progression free survival (PFS) per RECIST v1.1. Additional efficacy outcome measures were IRF-assessed overall response rate (ORR) per RECIST and mRECIST. Efficacy results are presented in Table 29 and Figure 7 .

ADA-positive patients by week 6 appeared to have similar overall survival compared to sorafenib-treated patients. In an exploratory analysis, inverse probability weighting was conducted to compare ADA-positive patients and ADA-negative patients in the intravenous atezolizumab and bevacizumab arm to the sorafenib arm. Inverse probability weighting factors were: baseline sum of longest tumor size (BSLD), baseline ECOG, baseline albumin, baseline LDH, sex, age, race, geographic region, weight, neutrophil-to-lymphocyte ratio, AFP (< 400 ng/mL vs ≥ 400 ng/mL), number of metastatic sites, MVI and/or EHS present at study entry, etiology (HBV vs. HCV vs. non-viral) and Child-Pugh Score (A5 vs. A6). The OS hazard ratio comparing the ADA-positive subgroup of the intravenous atezolizumab and bevacizumab arm to sorafenib was 0.93 (95% CI: 0.57, 1.53). The OS hazard ratio comparing the ADA-negative subgroup to sorafenib was 0.39 (95% CI: 0.26, 0.60). Figure 7 14.4 Melanoma The efficacy of TECENTRIQ HYBREZA in combination with cobimetinib and vemurafenib for the treatment of adult patients with BRAF V600 mutation-positive unresectable or metastatic melanoma has been established in adequate and well-controlled studies of intravenous atezolizumab in combination with bevacizumab for BRAF V600 mutation-positive unresectable or metastatic melanoma. Below is a description of the efficacy of intravenous atezolizumab in combination with cobimetinib and vemurafenib in this adequate and well-controlled melanoma trial. Metastatic Melanoma IMspire150 The efficacy of intravenous atezolizumab in combination with cobimetinib and vemurafenib was evaluated in a double-blind, randomized (1:1), placebo-controlled, multicenter trial (IMspire150; NCT02908672) conducted in 514 patients. Randomization was stratified by geographic location (North America vs. Europe vs. Australia, New Zealand, and others) and baseline lactate dehydrogenase (LDH) [less than or equal to upper limit of normal (ULN) vs. greater than ULN]. Eligible patients were required to have previously untreated unresectable or metastatic BRAF V600 mutation-positive melanoma as detected by a locally available test and centrally confirmed with the FoundationOne™ assay. Patients were excluded if they had history of autoimmune disease; administration of a live, attenuated vaccine within 28 days prior to randomization; administration of systemic immunostimulatory agents within 4 weeks or systemic immunosuppressive medications within 2 weeks prior to randomization; and active or untreated CNS metastases. Intravenous atezolizumab was initiated after patients received a 28-day treatment cycle of cobimetinib 60 mg orally once daily (21 days on/7 days off) and vemurafenib 960 mg orally twice daily Days 1-21 and 720 mg orally twice daily Days 22-28. Patients received intravenous atezolizumab 840 mg intravenous infusion over 60 minutes every 2 weeks in combination with cobimetinib 60 mg orally once daily and vemurafenib 720 mg orally twice daily, or placebo in combination with cobimetinib 60 mg orally once daily and vemurafenib 960 mg orally twice daily. Treatment continued until disease progression or unacceptable toxicity. There was no crossover at the time of disease progression. Tumor assessments were performed every 8 weeks (± 1 week) for the first 24 months and every 12 weeks (± 1 week) thereafter. The major efficacy outcome measure was investigator-assessed progression-free survival (PFS) per RECIST v1.1. Additional efficacy outcomes included PFS assessed by an independent central review, investigator-assessed ORR, OS, and DOR. The median age of the study population was 54 years (range: 22–88), 58% of patients were male, 95% were White, a baseline ECOG performance status of 0 (77%) or 1 (23%), 33% had elevated LDH, 94% had metastatic disease, 60% were Stage IV (M1C), 56% had less than three metastatic sites at baseline, 3% had prior treatment for brain metastases, 30% had liver metastases at baseline, and 14% had received prior adjuvant systemic therapy. Based on central testing, 74% were identified as having a V600E mutation, 11% as having V600K mutation, and 1% as having V600D or V600R mutations. Efficacy results are summarized in Table 30 and Figure 8 . Patients had a median survival follow up time of 18.9 months.

The hazard ratio for OS was 0.85 (95% CI: 0.64, 1.11) and the p-value was 0.2310. Figure 8 14.5 Alveolar Soft Part Sarcoma The efficacy of TECENTRIQ HYBREZA as monotherapy for the treatment of adult patients with unresectable or metastatic alveolar soft part sarcoma (ASPS) has been established in adequate and well-controlled studies of intravenous atezolizumab for ASPS. TECENTRIQ HYBREZA is not indicated for the treatment of pediatric patients. Below is a description of the efficacy of intravenous atezolizumab in this adequate and well-controlled ASPS trial. The efficacy of intravenous atezolizumab was evaluated in study ML39345 (NCT03141684), an open-label, single-arm study, in 49 adult and pediatric patients aged 2 years and older with unresectable or metastatic ASPS. Although this study enrolled pediatric patients, TECENTRIC HYBREZA is not indicated for use in pediatric patients. Eligible patients were required to have histologically or cytologically confirmed ASPS that was not curable by surgery, and an ECOG performance status of ≤ 2. Patients were excluded if they had known primary central nervous system (CNS) malignancy or symptomatic CNS metastases, known clinically significant liver disease, or history of idiopathic pulmonary fibrosis, pneumonitis, organizing pneumonia, or evidence of active pneumonitis on screening chest computed tomography (CT) scan. Adult patients received 1200 mg intravenously and pediatric patients received 15 mg/kg (up to a maximum of 1200 mg) intravenously once every 21 days until disease progression or unacceptable toxicity. The major efficacy outcomes were Overall Response Rate (ORR) and Duration of Response (DOR) by Independent Review Committee according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. A total of 49 patients were enrolled. The median age of patients was 31 years (range: 12–70); 2% of adult patients (n = 47) were ≥ 65 years of age and the pediatric patients (n = 2) were ≥ 12 years of age; 51% of patients were female, 55% White, 29% Black or African American, 10% Asian; 53% had an ECOG performance status of 0 and 45% had an ECOG performance status of 1. All patients had prior surgery for ASPS and 55% received at least one prior line of treatment for ASPS; 55% received radiotherapy and 53% received chemotherapy. Of the patients who reported staging at initial diagnosis, all were Stage IV. Efficacy results of this study are summarized in Table 31 . Table 31: Efficacy Results from Study ML39345 Endpoint All Patients (N=49) CI:confidence interval; N: number of patients; +: Censored Overall Response Rate (95% CI) 95% CI based on Clopper-Pearson exact method. 24% (13, 39) Complete responses, n 0 Partial responses, n (%) 12 (24) Duration of Response Median, month NE (95% CI) (17.0, NE) Range 1+, 41+ Durability of response ≥ 6 months, n (%) 8 (67%) ≥ 12 months, n (%) 5 (42%) 14.6 Patient Experience The IMscin002 study (NCT03735121) was a randomized, multi-center, open-label cross-over trial conducted in 179 patients with either PD-L1-positive early-stage NSCLC receiving adjuvant treatment or were chemotherapy-naïve with high PD-L1 stage IV NSCLC. Patients were randomized (1:1) to receive 3 cycles of TECENTRIQ HYBREZA followed by 3 cycles of intravenous atezolizumab (Arm A) or 3 cycles of intravenous atezolizumab followed by 3 cycles of TECENTRIQ HYBREZA (Arm B). Of the 126 eligible patients, 123 (98%) completed the patient preference questionnaire at the beginning of cycle 6 or after at least two consecutive cycles of each treatment method was administered in case of treatment discontinuation prior to cycle 6. Eighty-seven of 123 patients (71%) reported preferring subcutaneous administration of TECENTRIQ HYBREZA over intravenous atezolizumab and the most common reason was that administration required less time in the clinic; 26 out of 123 patients (21%) reported preferring intravenous atezolizumab over TECENTRIQ HYBREZA and the most common reason was that it felt more comfortable during administration; and 10 out of 123 patients (8%) had no preference for the route of administration. Patients in both arms could continue to receive treatment after the crossover period for up to 16 cycles (patients with early-stage NSCLC) or until disease progression or unacceptable toxicity (patients with stage IV NSCLC). Of the 107 patients who reached the treatment continuation period, 85 (79%) patients (42 from IV/SC and 43 from SC/IV) chose to continue treatment with the SC route of administration.

8.5 Geriatric Use Of 247 adult patients treated with TECENTRIQ HYBREZA as monotherapy in IMscin001, 45% were 65 years and over and 10% were 75 years and over. No overall differences in safety or effectiveness of TECENTRIQ HYBREZA have been observed between patients aged 65 years or older and younger adult patients. The safety of TECENTRIQ HYBREZA as monotherapy or in combination with other antineoplastic drugs for its approved indications [see Indications and Usage (1.1 , 1.2 , 1.3 , 1.4 , 1.5) ] has been established in adequate and well-controlled studies of intravenous atezolizumab as a single agent and in combination with other antineoplastic drugs. Below is a description of geriatric use information from the intravenous atezolizumab studies. Of 2,616 adult patients with metastatic NSCLC and other tumor types treated with monotherapy intravenous atezolizumab in clinical studies, 49% were 65 years and over and 15% were 75 years and over. Of 2,421 adult patients with NSCLC and EC-SCLC treated with intravenous atezolizumab in combination with other antineoplastic drugs in clinical studies, 48% were 65 years and over and 10% were 75 years and over. No overall differences in safety or effectiveness were observed between intravenous atezolizumab-treated patients aged 65 years or older and younger adult patients.

8.4 Pediatric Use The safety and effectiveness of TECENTRIQ HYBREZA have not been established in pediatric patients.

8.1 Pregnancy Risk Summary Based on its mechanism of action [see Clinical Pharmacology (12.1) ] , TECENTRIQ HYBREZA can cause fetal harm when administered to a pregnant woman . There are no available data on the use of TECENTRIQ HYBREZA in pregnant women. Animal studies have demonstrated that inhibition of the PD-L1/PD-1 pathway can lead to increased risk of immune-related rejection of the developing fetus resulting in fetal death (see Data ) . Advise females of reproductive potential of the potential risk to a fetus [see Warnings and Precautions (5.4) ] . In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal Data: TECENTRIQ HYBREZA for subcutaneous injection contains atezolizumab and hyaluronidase [see Description (11) ] . Atezolizumab : Animal reproduction studies have not been conducted with atezolizumab to evaluate its effect on reproduction and fetal development. A literature-based assessment of the effects on reproduction demonstrated that a central function of the PD-L1/PD-1 pathway is to preserve pregnancy by maintaining maternal immune tolerance to a fetus. Blockage of PD-L1 signaling has been shown in murine models of pregnancy to disrupt tolerance to a fetus and to result in an increase in fetal loss; therefore, potential risks of administering atezolizumab during pregnancy include increased rates of abortion or stillbirth. As reported in the literature, there were no malformations related to the blockade of PD-L1/PD-1 signaling in the offspring of these animals; however, immune-mediated disorders occurred in PD-1 and PD-L1 knockout mice. Based on its mechanism of action, fetal exposure to atezolizumab may increase the risk of developing immune-mediated disorders or altering the normal immune response. Hyaluronidase : In an embryo-fetal study, mice were dosed daily by subcutaneous injection during the period of organogenesis with hyaluronidase (recombinant human) at dose levels up to 2,200,000 U/kg, which is > 2,400 times higher than the human dose. The study found no evidence of teratogenicity. Reduced fetal weight and increased numbers of fetal resorptions were observed, with no effects found at a daily dose of 360,000 U/kg, which is > 400 times higher than the human dose. In a peri-and post-natal reproduction study, mice have been dosed daily by subcutaneous injection, with hyaluronidase (recombinant human) from implantation through lactation and weaning at dose levels up to 1,100,000 U/kg, which is > 1,200 times higher than the human dose. The study found no adverse effects on sexual maturation, learning and memory or fertility of the offspring.

Maternal IgG is known to be present in human milk. The effects of local gastrointestinal exposure and limited systemic exposure in the breastfed child to TECENTRIQ HYBREZA are unknown. Because of the potential for serious adverse reactions in breastfed children from TECENTRIQ HYBREZA, advise women not to breastfeed during treatment with TECENTRIQ HYBREZA and for 5 months after the last dose. 8.3 Females and Males of Reproductive Potential Based on its mechanism of action, TECENTRIQ HYBREZA can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1) ] . Pregnancy Testing Verify pregnancy status in females of reproductive potential prior to initiating TECENTRIQ HYBREZA [see Warnings and Precautions (5.4) and Use in Specific Populations (8.1) ] . Contraception Females: Advise females of reproductive potential to use effective contraception during treatment with TECENTRIQ HYBREZA and for 5 months following the last dose. Infertility Females: Based on animal studies, TECENTRIQ HYBREZA may impair fertility in females of reproductive potential while receiving TECENTRIQ HYBREZA treatment [see Nonclinical Toxicology (13.1) ] . 8.4 Pediatric Use The safety and effectiveness of TECENTRIQ HYBREZA have not been established in pediatric patients. 8.5 Geriatric Use Of 247 adult patients treated with TECENTRIQ HYBREZA as monotherapy in IMscin001, 45% were 65 years and over and 10% were 75 years and over.
