THE EASTERN COOPERATIVE ONCOLOGY GROUP (ECOG) PERFORMANCE STATUS

The Eastern Cooperative Oncology Group (ECOG), established in 1955, was one of the first groups to coordinate multicenter cancer clinical trials. The National Cancer Institute (NCI) is the primary funding source, and ECOG has evolved from a small consortium of institutions in the eastern United States to one of the largest clinical cancer research organizations in the country. As part of their work in the treatment of cancer, ECOG has developed the ECOG Performance Status (EPS), originally published in 1982 in the American Journal of Clinical Oncology. The use of the scales and the criteria in the EPS allows clinicians and researchers to determine an individual’s disease progression in terms of how the activities of daily living (ADL) are affected.

ECOG Performance Status
Grade	ECOG
0	Fully active, able to carry on all pre-disease performance without restriction
1	Restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature (eg, light housework, office work)
2	Ambulatory and capable of all self care but unable to carry out any work activities. Up and about more than 50 percent of waking hours
3	Capable of only limited self care, confined to bed or chair more than 50 percent of waking hours
4	Completely disabled. Cannot carry on any self care: Totally confined to bed or chair
5	Dead

THE CHILD-PUGH SCORE

Note: The Child-Pugh score is calculated by adding the scores of the five factors and can range from 5 to 15. Child-Pugh class is A (a score of 5-6), B (7-9), or C (10 or above). Decompensation indicates cirrhosis with a Child-Pugh score of 7 or more (class B). This level has been the accepted criterion for listing for liver transplantation.

Factor	Units	1	2	3
Serum bilirubin	mmol/L mg/dL	< 34 < 2.0	34-51 2.0-3.0	>51 >3.0
Serum albumin	g/L g/dL	>35 >3.5	30-35 3.0-3.5	< 30 < 3.0
Prothrombin time	Seconds prolonged INR	0-4 < 1.7	4-6 1.7-2.3	>6 >2.3
Ascites		None	Easily controlled	Poorly controlled
Hepatic encephalopathy		None	Minimal	Advanced

US FOOD AND DRUG ADMINISTRATION (FDA) STATUS

Atezolizumab (Tecentriq) was approved by the US Food and Drug Administration (FDA) on May 18, 2016, for the treatment of individuals with locally advanced or metastatic urothelial carcinoma who either have disease progression during or following platinum-containing chemotherapy or have disease progression within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy. The manufacturer has subsequently voluntarily removed this indication from the FDA labeling. Supplemental approvals for atezolizumab (Tecentriq) have since been issued by the FDA.

Refer to the atezolizumab (Tecentriq) prescribing information for further information on FDA-approved tests for determining Programmed Death-1 (PD-1), Programmed Death-Ligand 1 (PD-L1), epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK), c-ros oncogene 1 (ROS1), proto-oncogene B-Raf (BRAF), neurotrophic tyrosine kinase receptor (NTRK) 1/2/3, mesenchymal-epithelial transition (MET) exon 14 skipping mutation, and rearranged during transfection (RET) expression.

PEDIATRIC USE
The safety and effectiveness of atezolizumab (Tecentriq) for unresectable or metastatic alveolar soft part sarcoma have been established for pediatric individuals age 2 years and older. The safety and effectiveness of atezolizumab (Tecentriq) have not been established in pediatric individuals for any other indication.

Description

In a normal immune response, the body can recognize the presence of tumors and mount a response to eradicate them. The process of eradicating a tumor begins with antigen-presenting cells that gather and process the antigens released by tumors. This activates the T cells, which proliferate and attack the tumor.

Tumors have learned to evade the normal immune response by exploiting the immune checkpoint pathway. The Programmed Death Receptor-1 (PD-1) is a checkpoint protein expressed on the membrane of activated T cells. The Programmed Death-Ligand 1 (PD-L1) and the Programmed Death-Ligand 2 (PD-L2) are checkpoint proteins expressed on tumor cells and tumor-infiltrating immune cells. When PD-L1 and PD-L2 attach to PD-1 receptors on the T cells, the T cells become inhibited and will not attack the tumor; thus, the tumor can continue to proliferate.

Atezolizumab (Tecentriq) is a human monoclonal antibody and immune checkpoint inhibitor that binds to PD-L1 on tumor cells and tumor-infiltrating immune cells and blocks the interaction with PD-1 and B7.1 receptors on T cells and antigen-presenting cells. Consequently, the tumor is no longer able to inactivate the T cells, and the antitumor response continues.

ATEZOLIZUMAB (TECENTRIQ) INDICATIONS

ALVEOLAR SOFT PART SARCOMA
A soft tissue sarcoma is a type of cancer that starts in tissues like fat, muscle, nerves, or blood vessels. They are rare and slow growing, and often start in the arms or legs, but can spread to other parts of the body such as, frequently, the lungs. Alveolar soft part sarcomas (ASPS) are caused by a translocation of two chromosomes within the tumor cells themselves, so they cannot be passed on through the genes. These sarcomas tend to occur more frequently in adolescents and young adults. Treatment may involve surgical resection of the primary site either with or without adjunctive radiation therapy. If the tumor has spread, local treatment may not be adequate, and systemic therapy may be needed. Traditional chemotherapies are generally ineffective, however.

The efficacy of atezolizumab (Tecentriq) to treat untreated, advanced, or metastatic ASPS that is unresectable is being evaluated in an ongoing phase 2, nonrandomized, parallel assignment clinical trial in which one cohort receives only atezolizumab (Tecentriq) and a second cohort receives atezolizumab (Tecentriq) along with bevacizumab (Avastin^®; NCT03141684). The primary endpoint is objective response rate (ORR). The secondary endpoints are duration of response (DOR), progression-free survival (PFS), Response Evaluation Criteria in Solid Tumors (RECIST) response, immune biomarkers found in paired biopsies, and pediatric pharmacokinetics and anti-drug antibodies. At the time of the US Food and Drug Administration (FDA) approval, 49 adults and pediatric individuals aged 2 years and older were enrolled in the study. The ORR was 24 percent with no complete responses and 12 partial responses. The median DOR has not been reached, but at that time, ranged from 1 to 41 months. The clinical trial is continuing to recruit additional individuals and is expected to be complete late in 2023.

HEPATOCELLULAR CARCINOMA (HCC)
Hepatocellular carcinoma (HCC), the most common type of cancer in the liver, gallbladder, and bile ducts, is usually diagnosed at an advanced stage and is the third leading cause of cancer-related deaths worldwide.

In May 2020, the FDA approved atezolizumab (Tecentriq) in combination with bevacizumab (Avastin^®) for individuals with unresectable or metastatic HCC who had not received prior systemic therapy. Efficacy was investigated in IMbrave150 (NCT03434379), a multicenter, international, open-label, randomized trial in individuals with locally advanced unresectable or metastatic HCC who had not received prior systemic therapy. A total of 501 individuals were randomly assigned (2:1) to receive either atezolizumab (Tecentriq) 1200 mg as an intravenous (IV) infusion followed by bevacizumab 15 mg/kg IV on the same day, every 3 weeks, or sorafenib orally twice daily. The main efficacy outcome measures were overall survival (OS) and independent review facility (IRF)-assessed PFS per RECIST volume (v)1.1. Additional efficacy outcome measures were IRF-assessed ORR per RECIST v1.1 and modified RECIST (mRECIST). Median OS was not reached in the individuals who received atezolizumab (Tecentriq) plus bevacizumab and was 13.2 months (95 percent confidence interval (CI) 10.4 to not estimable [NE]) in the individuals who received sorafenib (hazard ratio [HR] 0.58; 95 percent CI 0.42 to 0.79; P=0.0006). Median PFS was 6.8 months (95 percent CI 5.7 to 8.3) versus 4.3 months (95 percent CI 4.0 to 5.6), respectively (HR 0.59; 95 percent CI 0.47 to 0.76; p<0.0001). The ORR per RECIST v1.1 was 27.3 percent (95 percent CI 22.5 to 32.5) in the atezolizumab (Tecentriq) plus bevacizumab group compared with 11.9 percent (95 percent CI 7.4 to 18.0) in the sorafenib group (P<0.0001). The ORR per mRECIST was 33.2 percent (95 percent CI 28.1 to 38.6) versus 13.3 percent (95 percent CI 8.4 to 19.6), respectively (P<0.0001). The most common adverse reactions (reported in 20 percent or greater of individuals) with atezolizumab (Tecentriq) plus bevacizumab in individuals with HCC were hypertension, fatigue, and proteinuria.

MELANOMA
Melanoma tumors are composed of abnormal melanocytes that have become cancer cells. Melanoma is much less common than some other types of skin cancers; however, it is more dangerous because it is much more likely to spread to other parts of the body if not caught and treated early.

In July 2020, the FDA approved atezolizumab (Tecentriq) in combination with cobimetinib and vemurafenib for individuals with proto-oncogene B-Raf (BRAF) V600 mutation-positive unresectable or metastatic melanoma. The efficacy of atezolizumab (Tecentriq) in combination with cobimetinib and vemurafenib was evaluated in a phase III, double-blind, randomized (1:1), placebo-controlled, multicenter trial (IMspire150; NCT02908672) conducted in 514 individuals. Eligible individuals were required to have previously untreated unresectable or metastatic BRAF V600 mutation-positive melanoma. Individuals were enrolled and randomly assigned to the atezolizumab (Tecentriq) group (n=256) or control group (n=258). At a median follow-up of 18.9 months (interquartile range [IQR] 10.4 to 23.8), PFS as assessed by the study investigator was significantly prolonged with atezolizumab (Tecentriq) versus control (15.1 versus 10.6 months; [HR] 0.78; 95 percent CI 0.63 to 0.97; P=0.025). The addition of atezolizumab (Tecentriq) to targeted therapy with vemurafenib and cobimetinib was safe and tolerable and significantly increased PFS in individuals with BRAF V600 mutation-positive advanced melanoma.

NON-SMALL CELL LUNG CANCER (NSCLC)
Lung cancer is the leading cause of cancer-related mortality in both men and women, not only in the United States but also throughout the world. In the United States, lung cancer is the second most common cancer. NSCLC accounts for approximately 85 percent of all lung cancers, and its subtype, squamous cell lung cancer, accounts for 25 to 30 percent of all lung cancers.

In October 2016, the FDA granted supplemental approval of atezolizumab (Tecentriq) for the treatment of individuals with metastatic NSCLC whose disease progressed during or following platinum-containing chemotherapy. Individuals with epidermal growth factor receptor (EGFR) or anaplastic lymphoma kinase (ALK) genomic tumor aberrations should have disease progression on a FDA-approved therapy for these aberrations prior to receiving atezolizumab (Tecentriq).

The safety and efficacy of atezolizumab (Tecentriq) for this indication was evaluated in two clinical trials. The first (NCT01903993; POPLAR) was a phase II multicenter, international, randomized, open-label trial in individuals with advanced or metastatic NSCLC who progressed during or following a platinum-containing regimen, regardless of PD-L1 expression. The study enrolled 287 individuals who were randomly assigned to receive either atezolizumab (Tecentriq) or docetaxel. The study showed that atezolizumab (Tecentriq) doubled the likelihood of survival in individuals whose cancer expressed the highest levels of PD-L1 compared with docetaxel chemotherapy. An improvement in survival was also observed in individuals who had medium and high or any level of PD-L1 expression.

The second study (NCT02008227; OAK) was a phase III multicenter, international, randomized, open-label trial that enrolled 1225 individuals in the same population comparing the same treatments as the phase II trial. The median OS was 13.8 months in the atezolizumab (Tecentriq) cohort versus 9.6 months in the docetaxel cohort (HR 0.74 [0.63 to 0.87]; P=0.0004).

In December 2018, atezolizumab (Tecentriq) also received the FDA-approved indication of NSCLC, in combination with bevacizumab, paclitaxel, and carboplatin, for the first-line treatment of adult individuals with metastatic nonsquamous NSCLC with no EGFR or ALK genomic tumor aberrations. The safety and efficacy of atezolizumab (Tecentriq) with bevacizumab, paclitaxel, and carboplatin was evaluated in IMpower150 (NCT02366143), a multicenter, international, randomized, open-label trial in 1202 individuals with metastatic non-squamous NSCLC. Three hundred ninety-three chemotherapy-naïve individuals with metastatic nonsquamous NSCLC received atezolizumab (Tecentriq) 1200 mg with bevacizumab 15 mg/kg, paclitaxel 175 mg/m2 or 200 mg/m2, and carboplatin area under the curve (AUC) 6 mg/mL/min every 3 weeks for a maximum of four or six cycles, followed by atezolizumab (Tecentriq) 1200 mg with bevacizumab 15 mg/kg every 3 weeks until disease progression or unacceptable toxicity. The median OS for individuals receiving atezolizumab (Tecentriq) with bevacizumab, paclitaxel, and carboplatin was 19.2 months versus 14.7 months in individuals not receiving atezolizumab (Tecentriq) along with the other infusions (HR 0.78; 95 percent CI, 0.64 to 0.96; P=0.016). The median PFS for individuals receiving atezolizumab (Tecentriq) with bevacizumab, paclitaxel, and carboplatin was 80.5 months versus 7.0 months in individuals not receiving atezolizumab (Tecentriq) along with other infusions (HR 0.71; 95 percent CI 0.59 to 0.85; P=0.002). The ORR for individuals receiving atezolizumab (Tecentriq) with bevacizumab, paclitaxel, and carboplatin was 55 percent (4 percent complete responses, 51 percent partial responses) versus 42 percent (1 percent complete responses, 41 percent partial responses) in individuals not receiving atezolizumab (Tecentriq) along with the other infusions. The median DOR for individuals receiving atezolizumab (Tecentriq) with bevacizumab, paclitaxel, and carboplatin was 10.8 months versus 6.5 months in individuals not receiving atezolizumab (Tecentriq) along with the other infusions.

In December 2019, the FDA approved atezolizumab (Tecentriq) for the first-line treatment of adult individuals with metastatic nonsquamous NSCLC with no EFGR or ALK genomic tumor aberrations, in combination with albumin-bound paclitaxel and carboplatin. This approval was based on a multicenter, randomized, open-label trial (NCT02367781; IMpower130) in individuals with stage IV nonsquamous NSCLC. Individuals were randomly assigned to one of the following treatment regimens: atezolizumab (Tecentriq), albumin-bound paclitaxel, and carboplatin for a maximum of four or six cycles followed by atezolizumab (Tecentriq) until disease progression or unacceptable toxicity, or albumin-bound paclitaxel and carboplatin for a maximum of four or six cycles followed by best supportive care or pemetrexed. Major efficacy outcome measures were PFS by RECIST v1.1 and OS in the subpopulation of individuals evaluated for and documented to have no EGFR or ALK genomic tumor aberrations intention to treat–wild type (ITT-WT). A total of 724 individuals were enrolled; of these, 681 (94 percent) were in the ITT-WT population. Fifty percent of individuals treated with atezolizumab (Tecentriq) died compared to 57 percent treated with placebo (HR, 0.80; 95 percent CI, 0.64 to 0.99; P=0.0384). The duration of response was 10.8 months in the atezolizumab (Tecentriq) group compared to 7.8 months in the placebo group.

In May 2020, the FDA approved atezolizumab (Tecentriq) for the first-line treatment of adult individuals with metastatic NSCLC whose tumors have high PD-L1 expression (PD-L1 stained 50 percent or greater of tumor cells [TC] [TC 50 percent or greater] or PD-L1 stained tumor-infiltrating immune cells [IC] covering 10 percent or greater of the tumor area [IC 10 percent or greater), with no EGFR or ALK genomic tumor aberrations. Efficacy was evaluated in IMpower110 (NCT02409342), a multicenter, international, randomized, open-label trial in individuals with stage IV NSCLC whose tumors express PD-L1 (TC 1 percent or greater or IC 1 percent or greater), who had received no prior chemotherapy for metastatic disease. Individuals were randomly assigned (1:1) to receive atezolizumab (Tecentriq) 1200 mg every 3 weeks until disease progression or unacceptable toxicity or platinum-based chemotherapy. The main efficacy outcome measure was OS. The trial demonstrated a statistically significant improvement in OS for individuals with high PD-L1 tumor expression receiving atezolizumab (Tecentriq) compared to those treated with platinum-based chemotherapy. Median OS was 20.2 months (95 percent CI 16.5 to NE) for individuals in the atezolizumab (Tecentriq) arm compared with 13.1 months (95 percent CI 7.4 to 16.5) in the chemotherapy arm (HR 0.59; 95 percent CI 0.40 to 0.89; p=0.0106). There was no statistically significant difference in OS for the other two PD-L1 subgroups (TC 5 percent or greater or IC 5 percent or greater; and TC 1 percent or greater or IC 1 percent or greater) at the interim or final analyses. Median PFS per investigator was 8.1 months (95 percent CI, 6.8 to 11.0) in the atezolizumab (Tecentriq) arm and 5.0 months (95 percent CI, 4.2 to 5.7) in the platinum-based chemotherapy arm (HR, 0.63; 95 percent CI, 0.45 to 0.88). Confirmed ORR per investigator was 38 percent (95 percent CI, 29 to 48) and 29 percent (95 percent CI, 20 to 39), respectively.

In October 2021, the FDA approved atezolizumab (Tecentriq) as adjuvant treatment following resection and platinum-based chemotherapy for adult individuals with Stage II to IIIA NSCLC whose tumors have PD-L1 expressions on 1 percent or greater of tumor cells. This was based on interim data from an ongoing Phase III, multicenter, international, randomized, open-label trial (NCT02486718; Impower010) that is evaluating the efficacy and safety of atezolizumab (Tecentriq) versus best supportive care (BSC) in individuals with Stage IB to Stage IIIA NSCLC following resection and adjuvant chemotherapy. The primary endpoint is disease-free survival (DFS). Some secondary endpoints include OS, percentage of individuals who are disease free at year 3, percentage of individuals who are disease free at year 5, percentage of individuals with adverse events, and percentage of individuals who develop anti-therapeutic antibodies to atezolizumab (Tecentriq). At the time of the interim analysis, the study demonstrated a statistically significant improvement in median DFS in the atezolizumab (Tecentriq) cohort versus the BSC cohort: not reached (NR) versus 35.3 months, respectively (HR, 0.66 [0.50 to 0.88]; P=0.004).

SMALL CELL LUNG CANCER (SCLC)
Small cell lung cancer (SCLC), previously known as oat cell carcinoma, is considered distinct from other lung cancers, which are called NSCLCs because of their clinical and biologic characteristics. SCLC is a neuroendocrine carcinoma that exhibits aggressive behavior, rapid growth, early spread to distant sites, sensitivity to chemotherapy and radiation, and frequent association with distinct paraneoplastic syndromes.

In March 2019, the FDA approved atezolizumab (Tecentriq) for the first-line treatment of adult individuals with extensive-stage SCLC, with carboplatin and etoposide. This approval was based on a randomized, multicenter, double-blind, placebo-controlled trial (NCT02763579) in 403 individuals with extensive-stage SCLC. Individuals were randomly assigned to atezolizumab (Tecentriq) in combination with carboplatin and etoposide or placebo in combination with carboplatin and etoposide. The major efficacy outcome measures were OS and PFS as assessed by investigator in the ITT population. Fifty-two percent of individuals treated with atezolizumab (Tecentriq) died compared to 66 percent of those treated with placebo (HR, 0.70; 95 percent CI, 0.54 to 0.91; P=0.0069). The duration of response was 4.2 months in the atezolizumab (Tecentriq) group compared to 3.9 months in placebo group.
