Immune-Mediated Pneumonitis

TECENTRIQ HYBREZA can cause immune-mediated pneumonitis, including fatal adverse reactions. The incidence of pneumonitis is higher in patients who have received prior thoracic radiation.

Immune-mediated pneumonitis occurred in 2% (5/247) of patients with locally advanced or metastatic NSCLC receiving TECENTRIQ HYBREZA as monotherapy in the IMscin001 trial [see Adverse Reactions (6.1)], including Grade 2 (0.8%), and Grade 1 (1.2%) events. Pneumonitis led to the withholding of TECENTRIQ HYBREZA in one patient.

Systemic corticosteroids were required in 40% (2/5) patients with pneumonitis who received TECENTRIQ HYBREZA as monotherapy. Pneumonitis resolved in both patients. The single patient in whom TECENTRIQ HYBREZA was withheld for pneumonitis reinitiated TECENTRIQ HYBREZA after symptom improvement.

Store vials under refrigeration at 2°C to 8°C (36°F to 46°F) in the original carton to protect from light. Do not freeze. Do not shake.

TECENTRIQ HYBREZA, in combination with cobimetinib and vemurafenib, is indicated for the treatment of adult patients with BRAF V600 mutation-positive unresectable or metastatic melanoma as determined by an FDA-approved test [see Dosage and Administration (2.1)].

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 results of intravenous atezolizumab in combination with cobimetinib and vemurafenib in this adequate and well-controlled melanoma trial.

TECENTRIQ HYBREZA is a fixed-combination drug product containing atezolizumab and hyaluronidase (human recombinant).

• Atezolizumab is a programmed cell death ligand 1 (PD-L1) blocking antibody. 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.

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 ADA 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 ADA 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.

TECENTRIQ HYBREZA is contraindicated in patients with known hypersensitivity to hyaluronidase or to any of its excipients.

The following clinically significant adverse reactions are described elsewhere in the labeling:

• Severe and Fatal Immune-Mediated Adverse Reactions [see Warnings and Precautions (5.1)]
• Infusion-Related Reactions [see Warnings and Precautions (5.2)]
• Complications of Allogeneic HSCT after PD-1/PD-L1 Inhibitors [see Warnings and Precautions (5.3)]

The exposure-response relationship and time course of pharmacodynamic response for the safety and effectiveness of atezolizumab and hyaluronidase have not been fully characterized.

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.

TECENTRIQ HYBREZA is a combination of atezolizumab, a programmed death-ligand 1 (PD-L1) blocking antibody, and hyaluronidase, an endoglycosidase indicated:

Non-Small Cell Lung Cancer (NSCLC)

• as adjuvant treatment following resection and platinum-based chemotherapy for adult patients with Stage II to IIIA NSCLC whose tumors have PD-L1 expression on ≥ 1% of tumor cells, as determined by an FDA-approved test. (1.1)
• for the 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%]), as determined by an FDA-approved test, with no EGFR or ALK genomic tumor aberrations. (1.1)

• in combination with paclitaxel protein-bound and carboplatin for the first-line treatment of adult patients with metastatic non-squamous NSCLC with no EGFR or ALK genomic tumor aberrations. (1.1)
• for the treatment of adult patients with metastatic NSCLC who have disease progression during or following platinum-containing chemotherapy. Patients with EGFR or ALK genomic tumor aberrations should have disease progression on FDA-approved therapy for NSCLC harboring these aberrations prior to receiving TECENTRIQ HYBREZA. (1.1)

Small Cell Lung Cancer (SCLC)

• in combination with carboplatin and etoposide, for the first-line treatment of adult patients with extensive-stage small cell lung cancer (ES-SCLC). (1.2)
• in combination with lurbinectedin, for the maintenance treatment of adult patients with ES-SCLC whose disease has not progressed after first-line induction therapy with TECENTRIQ HYBREZA or intravenous atezolizumab, and carboplatin plus etoposide. (1.2)

Hepatocellular Carcinoma (HCC)

• in combination with bevacizumab for the treatment of adult patients with unresectable or metastatic HCC who have not received prior systemic therapy. (1.3)

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.

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.

• 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.

Based on its mechanism of action, 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.

Verify pregnancy status of females of reproductive potential prior to initiating TECENTRIQ HYBREZA. Advise females of reproductive potential of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with TECENTRIQ HYBREZA and for 5 months after the last dose [see Use in Specific Populations (8.1, 8.3)].

• TECENTRIQ HYBREZA, in combination with carboplatin and etoposide, is indicated for the first-line treatment of adult patients with extensive-stage small cell lung cancer (ES-SCLC).
• TECENTRIQ HYBREZA, in combination with lurbinectedin, is indicated for the maintenance treatment of adult patients with ES-SCLC whose disease has not progressed after first-line induction therapy with TECENTRIQ HYBREZA or intravenous atezolizumab, carboplatin and etoposide.

• Immune-Mediated Adverse Reactions
  • Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue, including the following: immune-mediated pneumonitis, immune-mediated colitis, immune-mediated hepatitis, immune-mediated endocrinopathies, immune-mediated dermatologic adverse reactions, immune-mediated nephritis and renal dysfunction, and solid organ transplant rejection. (5.1)
  • Monitor for early identification and management. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment.
  • Withhold or permanently discontinue based on severity and type of reaction.
• Infusion-Related Reactions: Pause or slow the rate of injection, or permanently discontinue based on severity of the reaction. (5.2)
• Complications of Allogeneic HSCT: Fatal and other serious complications can occur in patients who receive allogeneic HSCT before or after being treated with a PD-1/PD-L1 blocking antibody. Follow patients closely for evidence of transplant-related complications and intervene promptly. (5.3)
• Embryo-Fetal Toxicity: Can cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus and use of effective contraception. (5.4, 8.1, 8.3)

The efficacy of TECENTRIQ HYBREZA in combination with chemotherapy 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. Below is a description of the efficacy results of these adequate and well-controlled studies of intravenous atezolizumab in combination with chemotherapy in ES-SCLC (IMpower133 and IMforte studies).

TECENTRIQ HYBREZA, as monotherapy, is indicated for the treatment of adult patients and pediatric patients (12 years of age and older who weigh 40 kg or greater) with unresectable or metastatic alveolar soft part sarcoma (ASPS).

TECENTRIQ HYBREZA can cause severe or life-threatening infusion-related reactions, including Grade 3 adverse reactions and anaphylaxis. Monitor for signs and symptoms of infusion-related reactions. Pause, slow the rate of, or permanently discontinue TECENTRIQ HYBREZA based on the severity [see Dosage and Administration (2.3)]. For Grade 1 or 2 infusion-related reactions, consider using pre-medications with subsequent doses.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The efficacy of TECENTRIQ HYBREZA as monotherapy for the treatment of adult patients and pediatric patients 12 years of age or older with unresectable or metastatic alveolar soft part sarcoma (ASPS) has been established in adequate and well-controlled studies of intravenous atezolizumab for ASPS. Below is a description of the efficacy results 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. 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 34.

Advise the patient to read the FDA-approved patient labeling (Medication Guide).

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.

No dose reduction for TECENTRIQ HYBREZA is recommended. In general, withhold TECENTRIQ HYBREZA for severe (Grade 3) immune-mediated adverse reactions. Permanently discontinue TECENTRIQ HYBREZA for life-threatening (Grade 4) immune-mediated adverse reactions, recurrent severe (Grade 3) immune-mediated reactions that require systemic immunosuppressive treatment, or an inability to reduce the daily corticosteroid dosage to 10 mg or less of prednisone or equivalent corticosteroid dosage within 12 weeks of initiating corticosteroids.

Dosage modifications for TECENTRIQ HYBREZA for adverse reactions that require management different from these general guidelines are summarized in Table 2.

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)].

• TECENTRIQ HYBREZA has different recommended dosage and administration than intravenous atezolizumab products.
  • To reduce the risk of medication errors, prior to administration, check the vial labels to ensure that the drug being prepared is subcutaneously administered TECENTRIQ HYBREZA and not intravenously administered atezolizumab.
  • Do not substitute TECENTRIQ HYBREZA for or with intravenous atezolizumab products because they have different recommended dosages.
  • Adult patients who are treated with intravenous atezolizumab can switch to subcutaneous TECENTRIQ HYBREZA at their next scheduled dose. Adult patients who are treated with TECENTRIQ HYBREZA can switch to intravenous atezolizumab at their next scheduled dose.
  • Pediatric patients 12 years of age and older who weigh 40 kg or greater and are treated with intravenous atezolizumab can switch to subcutaneous TECENTRIQ HYBREZA at their next scheduled dose [see Indications and Usage (1.5)]. Pediatric patients who are treated with TECENTRIQ HYBREZA can switch to intravenous atezolizumab at their next scheduled dose.
• TECENTRIQ HYBREZA is for subcutaneous use in the thigh only. Administer over approximately 7 minutes. Inject in healthy skin and never into areas where the skin is red, bruised, tender, or hard.
• When possible, alternate injections between the left and right thigh. Ensure the injection site is at least 2.5 cm from the previous site.
• Do not administer TECENTRIQ HYBREZA intravenously.
• TECENTRIQ HYBREZA must be administered by a healthcare professional.
• Do not administer the remaining volume in the tubing to the patient.
• If using concomitant subcutaneous drugs, administer at sites other than the thighs.

The recommended dosage of TECENTRIQ HYBREZA in adult patients and pediatric patients (12 years of age and older who weigh 40 kg or greater) is one 15 mL injection (containing 1,875 mg of atezolizumab and 30,000 units of hyaluronidase, referred to as TECENTRIQ HYBREZA) administered subcutaneously in the thigh over approximately 7 minutes every 3 weeks.

The recommended dosage for pediatric patients 12 years of age and older who weigh less than 40 kg has not been established [see Use in Specific Populations (8.4), Clinical Pharmacology (12.3)].

Administration instructions for TECENTRIQ HYBREZA as monotherapy and in combination with other therapeutic agents are presented in Table 1. For the recommended dosage of each therapeutic agent administered in combination with TECENTRIQ HYBREZA refer to the product's respective Prescribing Information.

TECENTRIQ HYBREZA is a monoclonal antibody that belongs to a class of drugs that bind to either the programmed death-receptor 1 (PD-1) or the PD-ligand 1 (PD-L1), blocking the PD-1/PD-L1 pathway, thereby removing inhibition of the immune response, potentially breaking peripheral tolerance and inducing immune-mediated adverse reactions. Important immune-mediated adverse reactions listed under Warnings and Precautions may not include all possible severe and fatal immune-mediated reactions.

Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue. Immune-mediated adverse reactions can occur at any time after starting a PD-1/PD-L1 blocking antibody. While immune-mediated adverse reactions usually manifest during treatment with PD-1/PD-L1 blocking antibodies, immune-mediated adverse reactions can also manifest after discontinuation of PD-1/PD-L1 blocking antibodies.

Early identification and management of immune-mediated adverse reactions are essential to ensure safe use of PD-1/PD-L1 blocking antibodies. Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate.

Withhold or permanently discontinue TECENTRIQ HYBREZA depending on severity [see Dosage and Administration (2.3)]. In general, if TECENTRIQ HYBREZA requires interruption or discontinuation, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose immune-mediated adverse reactions are not controlled with corticosteroid therapy.

Toxicity management guidelines for adverse reactions that do not necessarily require systemic steroids (e.g., endocrinopathies and dermatologic reactions) are discussed below.

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).

Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with a PD-1/PD-L1 blocking antibody. Transplant-related complications include hyperacute graft-versus-host disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between PD-1/PD-L1 blockage and allogeneic HSCT.

Follow patients closely for evidence of transplant-related complications and intervene promptly. Consider the benefits versus risks of treatment with a PD-1/PD-L1 blocking antibody prior to or after an allogeneic HSCT.

Select adult patients with:

• Stage II to IIIA NSCLC for adjuvant treatment with TECENTRIQ HYBREZA as a monotherapy (following tumor resection and platinum-based chemotherapy) based on PD-L1 expression on tumor cells [see Clinical Studies (14.1)].
• Metastatic NSCLC for first-line treatment with TECENTRIQ HYBREZA as monotherapy based on the PD-L1 expression on tumor cells or on tumor-infiltrating immune cells [see Clinical Studies (14.1)].
• Unresectable or metastatic melanoma for treatment with TECENTRIQ HYBREZA in combination with cobimetinib and vemurafenib after confirming the presence of a BRAF V600 mutation [see Clinical Studies (14.4)].

Information on FDA-approved tests for the determination of PD-L1 expression in metastatic NSCLC or for detection of BRAF V600 mutations in melanoma is available at: http://www.fda.gov/CompanionDiagnostics.

Immune-Mediated Pneumonitis

TECENTRIQ HYBREZA can cause immune-mediated pneumonitis, including fatal adverse reactions. The incidence of pneumonitis is higher in patients who have received prior thoracic radiation.

Immune-mediated pneumonitis occurred in 2% (5/247) of patients with locally advanced or metastatic NSCLC receiving TECENTRIQ HYBREZA as monotherapy in the IMscin001 trial [see Adverse Reactions (6.1)], including Grade 2 (0.8%), and Grade 1 (1.2%) events. Pneumonitis led to the withholding of TECENTRIQ HYBREZA in one patient.

Systemic corticosteroids were required in 40% (2/5) patients with pneumonitis who received TECENTRIQ HYBREZA as monotherapy. Pneumonitis resolved in both patients. The single patient in whom TECENTRIQ HYBREZA was withheld for pneumonitis reinitiated TECENTRIQ HYBREZA after symptom improvement.

Store vials under refrigeration at 2°C to 8°C (36°F to 46°F) in the original carton to protect from light. Do not freeze. Do not shake.

TECENTRIQ HYBREZA, in combination with cobimetinib and vemurafenib, is indicated for the treatment of adult patients with BRAF V600 mutation-positive unresectable or metastatic melanoma as determined by an FDA-approved test [see Dosage and Administration (2.1)].

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 results of intravenous atezolizumab in combination with cobimetinib and vemurafenib in this adequate and well-controlled melanoma trial.

TECENTRIQ HYBREZA is a fixed-combination drug product containing atezolizumab and hyaluronidase (human recombinant).

• Atezolizumab is a programmed cell death ligand 1 (PD-L1) blocking antibody. 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.

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 ADA 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 ADA 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.

TECENTRIQ HYBREZA is contraindicated in patients with known hypersensitivity to hyaluronidase or to any of its excipients.

The following clinically significant adverse reactions are described elsewhere in the labeling:

• Severe and Fatal Immune-Mediated Adverse Reactions [see Warnings and Precautions (5.1)]
• Infusion-Related Reactions [see Warnings and Precautions (5.2)]
• Complications of Allogeneic HSCT after PD-1/PD-L1 Inhibitors [see Warnings and Precautions (5.3)]

The exposure-response relationship and time course of pharmacodynamic response for the safety and effectiveness of atezolizumab and hyaluronidase have not been fully characterized.

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.

TECENTRIQ HYBREZA is a combination of atezolizumab, a programmed death-ligand 1 (PD-L1) blocking antibody, and hyaluronidase, an endoglycosidase indicated:

Non-Small Cell Lung Cancer (NSCLC)

• as adjuvant treatment following resection and platinum-based chemotherapy for adult patients with Stage II to IIIA NSCLC whose tumors have PD-L1 expression on ≥ 1% of tumor cells, as determined by an FDA-approved test. (1.1)
• for the 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%]), as determined by an FDA-approved test, with no EGFR or ALK genomic tumor aberrations. (1.1)
• in combination with bevacizumab, paclitaxel, and carboplatin, for the first-line treatment of adult patients with metastatic non-squamous NSCLC with no EGFR or ALK genomic tumor aberrations. (1.1)
• in combination with paclitaxel protein-bound and carboplatin for the first-line treatment of adult patients with metastatic non-squamous NSCLC with no EGFR or ALK genomic tumor aberrations. (1.1)
• for the treatment of adult patients with metastatic NSCLC who have disease progression during or following platinum-containing chemotherapy. Patients with EGFR or ALK genomic tumor aberrations should have disease progression on FDA-approved therapy for NSCLC harboring these aberrations prior to receiving TECENTRIQ HYBREZA. (1.1)

Small Cell Lung Cancer (SCLC)

• in combination with carboplatin and etoposide, for the first-line treatment of adult patients with extensive-stage small cell lung cancer (ES-SCLC). (1.2)
• in combination with lurbinectedin, for the maintenance treatment of adult patients with ES-SCLC whose disease has not progressed after first-line induction therapy with TECENTRIQ HYBREZA or intravenous atezolizumab, and carboplatin plus etoposide. (1.2)

Hepatocellular Carcinoma (HCC)

• in combination with bevacizumab for the treatment of adult patients with unresectable or metastatic HCC who have not received prior systemic therapy. (1.3)

Melanoma

• in combination with cobimetinib and vemurafenib for the treatment of adult patients with BRAF V600 mutation-positive unresectable or metastatic melanoma as determined by an FDA-approved test. (1.4)

Alveolar Soft Part Sarcoma (ASPS)

• for the treatment of adult patients and pediatric patients (12 years of age and older who weigh 40 kg or greater) with unresectable or metastatic ASPS. (1.5)

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.

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.

• 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.

Based on its mechanism of action, 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.

Verify pregnancy status of females of reproductive potential prior to initiating TECENTRIQ HYBREZA. Advise females of reproductive potential of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with TECENTRIQ HYBREZA and for 5 months after the last dose [see Use in Specific Populations (8.1, 8.3)].

• TECENTRIQ HYBREZA, in combination with carboplatin and etoposide, is indicated for the first-line treatment of adult patients with extensive-stage small cell lung cancer (ES-SCLC).
• TECENTRIQ HYBREZA, in combination with lurbinectedin, is indicated for the maintenance treatment of adult patients with ES-SCLC whose disease has not progressed after first-line induction therapy with TECENTRIQ HYBREZA or intravenous atezolizumab, carboplatin and etoposide.

• Immune-Mediated Adverse Reactions
  • Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue, including the following: immune-mediated pneumonitis, immune-mediated colitis, immune-mediated hepatitis, immune-mediated endocrinopathies, immune-mediated dermatologic adverse reactions, immune-mediated nephritis and renal dysfunction, and solid organ transplant rejection. (5.1)
  • Monitor for early identification and management. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment.
  • Withhold or permanently discontinue based on severity and type of reaction.
• Infusion-Related Reactions: Pause or slow the rate of injection, or permanently discontinue based on severity of the reaction. (5.2)
• Complications of Allogeneic HSCT: Fatal and other serious complications can occur in patients who receive allogeneic HSCT before or after being treated with a PD-1/PD-L1 blocking antibody. Follow patients closely for evidence of transplant-related complications and intervene promptly. (5.3)
• Embryo-Fetal Toxicity: Can cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus and use of effective contraception. (5.4, 8.1, 8.3)

The efficacy of TECENTRIQ HYBREZA in combination with chemotherapy 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. Below is a description of the efficacy results of these adequate and well-controlled studies of intravenous atezolizumab in combination with chemotherapy in ES-SCLC (IMpower133 and IMforte studies).

TECENTRIQ HYBREZA, as monotherapy, is indicated for the treatment of adult patients and pediatric patients (12 years of age and older who weigh 40 kg or greater) with unresectable or metastatic alveolar soft part sarcoma (ASPS).

TECENTRIQ HYBREZA can cause severe or life-threatening infusion-related reactions, including Grade 3 adverse reactions and anaphylaxis. Monitor for signs and symptoms of infusion-related reactions. Pause, slow the rate of, or permanently discontinue TECENTRIQ HYBREZA based on the severity [see Dosage and Administration (2.3)]. For Grade 1 or 2 infusion-related reactions, consider using pre-medications with subsequent doses.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The efficacy of TECENTRIQ HYBREZA as monotherapy for the treatment of adult patients and pediatric patients 12 years of age or older with unresectable or metastatic alveolar soft part sarcoma (ASPS) has been established in adequate and well-controlled studies of intravenous atezolizumab for ASPS. Below is a description of the efficacy results 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. 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 34.

Advise the patient to read the FDA-approved patient labeling (Medication Guide).

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.

No dose reduction for TECENTRIQ HYBREZA is recommended. In general, withhold TECENTRIQ HYBREZA for severe (Grade 3) immune-mediated adverse reactions. Permanently discontinue TECENTRIQ HYBREZA for life-threatening (Grade 4) immune-mediated adverse reactions, recurrent severe (Grade 3) immune-mediated reactions that require systemic immunosuppressive treatment, or an inability to reduce the daily corticosteroid dosage to 10 mg or less of prednisone or equivalent corticosteroid dosage within 12 weeks of initiating corticosteroids.

Dosage modifications for TECENTRIQ HYBREZA for adverse reactions that require management different from these general guidelines are summarized in Table 2.

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)].

• TECENTRIQ HYBREZA has different recommended dosage and administration than intravenous atezolizumab products.
  • To reduce the risk of medication errors, prior to administration, check the vial labels to ensure that the drug being prepared is subcutaneously administered TECENTRIQ HYBREZA and not intravenously administered atezolizumab.
  • Do not substitute TECENTRIQ HYBREZA for or with intravenous atezolizumab products because they have different recommended dosages.
  • Adult patients who are treated with intravenous atezolizumab can switch to subcutaneous TECENTRIQ HYBREZA at their next scheduled dose. Adult patients who are treated with TECENTRIQ HYBREZA can switch to intravenous atezolizumab at their next scheduled dose.
  • Pediatric patients 12 years of age and older who weigh 40 kg or greater and are treated with intravenous atezolizumab can switch to subcutaneous TECENTRIQ HYBREZA at their next scheduled dose [see Indications and Usage (1.5)]. Pediatric patients who are treated with TECENTRIQ HYBREZA can switch to intravenous atezolizumab at their next scheduled dose.
• TECENTRIQ HYBREZA is for subcutaneous use in the thigh only. Administer over approximately 7 minutes. Inject in healthy skin and never into areas where the skin is red, bruised, tender, or hard.
• When possible, alternate injections between the left and right thigh. Ensure the injection site is at least 2.5 cm from the previous site.
• Do not administer TECENTRIQ HYBREZA intravenously.
• TECENTRIQ HYBREZA must be administered by a healthcare professional.
• Do not administer the remaining volume in the tubing to the patient.
• If using concomitant subcutaneous drugs, administer at sites other than the thighs.

The recommended dosage of TECENTRIQ HYBREZA in adult patients and pediatric patients (12 years of age and older who weigh 40 kg or greater) is one 15 mL injection (containing 1,875 mg of atezolizumab and 30,000 units of hyaluronidase, referred to as TECENTRIQ HYBREZA) administered subcutaneously in the thigh over approximately 7 minutes every 3 weeks.

The recommended dosage for pediatric patients 12 years of age and older who weigh less than 40 kg has not been established [see Use in Specific Populations (8.4), Clinical Pharmacology (12.3)].

Administration instructions for TECENTRIQ HYBREZA as monotherapy and in combination with other therapeutic agents are presented in Table 1. For the recommended dosage of each therapeutic agent administered in combination with TECENTRIQ HYBREZA refer to the product's respective Prescribing Information.

TECENTRIQ HYBREZA is a monoclonal antibody that belongs to a class of drugs that bind to either the programmed death-receptor 1 (PD-1) or the PD-ligand 1 (PD-L1), blocking the PD-1/PD-L1 pathway, thereby removing inhibition of the immune response, potentially breaking peripheral tolerance and inducing immune-mediated adverse reactions. Important immune-mediated adverse reactions listed under Warnings and Precautions may not include all possible severe and fatal immune-mediated reactions.

Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue. Immune-mediated adverse reactions can occur at any time after starting a PD-1/PD-L1 blocking antibody. While immune-mediated adverse reactions usually manifest during treatment with PD-1/PD-L1 blocking antibodies, immune-mediated adverse reactions can also manifest after discontinuation of PD-1/PD-L1 blocking antibodies.

Early identification and management of immune-mediated adverse reactions are essential to ensure safe use of PD-1/PD-L1 blocking antibodies. Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. Evaluate liver enzymes, creatinine, and thyroid function at baseline and periodically during treatment. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate.

Withhold or permanently discontinue TECENTRIQ HYBREZA depending on severity [see Dosage and Administration (2.3)]. In general, if TECENTRIQ HYBREZA requires interruption or discontinuation, administer systemic corticosteroid therapy (1 to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose immune-mediated adverse reactions are not controlled with corticosteroid therapy.

Toxicity management guidelines for adverse reactions that do not necessarily require systemic steroids (e.g., endocrinopathies and dermatologic reactions) are discussed below.

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).

Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with a PD-1/PD-L1 blocking antibody. Transplant-related complications include hyperacute graft-versus-host disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between PD-1/PD-L1 blockage and allogeneic HSCT.

Follow patients closely for evidence of transplant-related complications and intervene promptly. Consider the benefits versus risks of treatment with a PD-1/PD-L1 blocking antibody prior to or after an allogeneic HSCT.

Select adult patients with:

• Stage II to IIIA NSCLC for adjuvant treatment with TECENTRIQ HYBREZA as a monotherapy (following tumor resection and platinum-based chemotherapy) based on PD-L1 expression on tumor cells [see Clinical Studies (14.1)].
• Metastatic NSCLC for first-line treatment with TECENTRIQ HYBREZA as monotherapy based on the PD-L1 expression on tumor cells or on tumor-infiltrating immune cells [see Clinical Studies (14.1)].
• Unresectable or metastatic melanoma for treatment with TECENTRIQ HYBREZA in combination with cobimetinib and vemurafenib after confirming the presence of a BRAF V600 mutation [see Clinical Studies (14.4)].
