IMPORTANT NOTE:
The purpose of this policy is to provide general information applicable to the administration of health benefits that Horizon Blue Cross Blue Shield of New Jersey and Horizon Healthcare of New Jersey, Inc. (collectively “Horizon BCBSNJ”) insures or administers. If the member’s contract benefits differ from the medical policy, the contract prevails. Although a service, supply or procedure may be medically necessary, it may be subject to limitations and/or exclusions under a member’s benefit plan. If a service, supply or procedure is not covered and the member proceeds to obtain the service, supply or procedure, the member may be responsible for the cost. Decisions regarding treatment and treatment plans are the responsibility of the physician. This policy is not intended to direct the course of clinical care a physician provides to a member, and it does not replace a physician’s independent professional clinical judgment or duty to exercise special knowledge and skill in the treatment of Horizon BCBSNJ members. Horizon BCBSNJ is not responsible for, does not provide, and does not hold itself out as a provider of medical care. The physician remains responsible for the quality and type of health care services provided to a Horizon BCBSNJ member.
Horizon BCBSNJ medical policies do not constitute medical advice, authorization, certification, approval, explanation of benefits, offer of coverage, contract or guarantee of payment.

Imfinzi (durvalumab) is a programmed death-ligand 1 (PD-L1) blocking antibody. Imfinzi is specifically indicated for the treatment of patients with locally advanced or metastatic urothelial carcinoma who:
1) have disease progression during or following platinum-containing chemotherapy
2) have disease progression within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy
This indication is approved under accelerated approval based on tumor response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials.
The efficacy of Imfinzi was evaluated in Study 1, the urothelial cancer cohort of a multicenter, multicohort, open-label clinical trial. In Study 1, 182 patients with locally advanced or metastatic urothelial carcinoma were enrolled. Patients had progressed while on or after a platinum based therapy, including those who progressed within 12 months of receiving therapy in a neoadjuvant or adjuvant setting. These patients had initiated durvalumab therapy at least 13 weeks prior to the data cut-off date. The trial excluded patients with a history of immunodeficiency; medical conditions that required systemic immunosuppression (not to exceed 10 mg/day of prednisone or equivalent); history of severe autoimmune disease; untreated CNS metastases; HIV; active tuberculosis, or hepatitis B or C infection. All patients received Imfinzi 10 mg/kg via intravenous infusion every 2 weeks for up to 12 months or until unacceptable toxicity or disease progression. Tumor assessments were performed at weeks 6, 12 and 16, then every 8 weeks for the first year and every 12 weeks thereafter.
The major efficacy outcome measures were confirmed Objective Response Rate (ORR) according to RECIST v1.1 as assessed by Blinded Independent Central Review (BICR), and duration of response (DoR). The median follow-up time was 5.6 months. The ORR in all patients treated with Imfinzi was 31 patients [17.0% (95% CI, 11.9-23.3%)]; of these patients, 5 (16.1%) had a complete response and 26 (83.9%) had a partial response. Among the total 31 responding patients, 14 patients (45%) had ongoing responses of 6 months or longer and five patients (16%) had ongoing responses of 12 months or longer. The ORR based on PD-L1 expression was as follows:
-PD-L1 High: 26.3% (95% CI, 17.8-36.4%)
-PD-L1 Low/Negative: 4.1% (95% CI, 0.9-11.5%)
-PD-L1 Not Evaluable: 21.4% (95% CI, 4.7-50.8%)
The most common adverse reactions (≥15%) seen in clinical trial with Imfinzi were fatigue (39%), musculoskeletal pain (24%), constipation (21%), decreased appetite (19%), nausea (16%), peripheral edema (15%) and urinary tract infection (15%). The most common Grade 3 or 4 adverse reactions (≥3%) were fatigue, urinary tract infection, musculoskeletal pain, abdominal pain, dehydration, and general physical health deterioration. Eight patients (4.4%) who were treated with Imfinzi experienced Grade 5 adverse events of cardiorespiratory arrest, general physical health deterioration, sepsis, ileus, pneumonitis, or immune mediated hepatitis. Three additional patients were experiencing infection and disease progression at the time of death. IMFINZI was discontinued for adverse reactions in 3.3% of patients. Serious adverse reactions occurred in 46% of patients. The most frequent serious adverse reactions (>2%) were acute kidney injury (4.9%), urinary tract infection (4.4%), musculoskeletal pain (4.4%), liver injury (3.3%), general physical health deterioration (3.3%), sepsis, abdominal pain, pyrexia/tumor associated fever (2.7% each).
In February 2018, Imfinzi was approved for the indication of unresectable, stage III non-small cell lung cancer (NSCLC) whose disease has not progressed following concurrent platinum-based chemotherapy and radiation therapy. The FDA approval was based on a multicenter, randomized, double-blind placebo-controlled study (PACIFIC trial) in 713 patients with unresectable stage III NSCLC who completed at least two cycles of concurrent platinum-based chemotherapy and definitive radiation within 42 days prior to initiation of the study. Patients were randomized 2:1 to receive Imfinzi 10mg/kg or placebo intravenously every 2 weeks for up to 12 months or until unacceptable toxicity or confirmed RECIST 1.1-defined progression. Assessment of tumor status was performed every 8 weeks. The median progression-free survival was 16.8 months for Imfinzi (95% CI, 13.0-18.1) vs 5.6 months for placebo (95% CI, 4.6-7.8). The response rate was significantly higher with Imfinzi than with placebo (28.4% vs 16.0%, P<0.001) and 16.5% of those who received Imfinzi vs 27.7% placebo had disease progression. The most frequent adverse events of any grade related to Imfinzi were diarrhea, pneumonitis, rash and pruritus. Grade 3 or 4 adverse events occurred at similar rates in both groups, pneumonia being the most common.
On March 27, 2020, the FDA approved Imfinzi in combination with etoposide and either carboplatin or cisplatin as first-line treatment of patients with extensive-stage small cell lung cancer (ES-SCLC). Efficacy of this combination in patients with previously untreated ES-SCLC was investigated in CASPIAN, a randomized, multicenter, active-controlled, open-label, trial (NCT03043872). The evaluation was based on the comparison of patients randomized to Imfinzi plus chemotherapy vs. chemotherapy alone. The major efficacy outcome measure was overall survival (OS). Additional efficacy outcome measures were investigator-assessed progression-free survival (PFS) and objective response rate (ORR). Median OS was 13.0 months (95% CI: 11.5, 14.8) in the Imfinzi plus chemotherapy arm compared with 10.3 months (95% CI: 9.3, 11.2) in the chemotherapy alone arm (hazard ratio 0.73; 95% CI: 0.59, 0.91; p=0.0047). PFS showed a HR of 0.78 (95% CI: 0.65, 0.94), with median PFS of 5.1 months (95% CI: 4.7, 6.2) in the Imfinzi plus chemotherapy arm and 5.4 months (95% CI: 4.8, 6.2) in the chemotherapy alone arm. ORR was 68% (95% CI: 62%, 73%) in the Imfinzi plus chemotherapy arm and 58% (95% CI: 52%, 63%) in the chemotherapy alone arm. The most common adverse reactions (≥20%) in patients with ES-SCLC were nausea, fatigue/asthenia, and alopecia. For ES-SCLC, Imfinzi is to be administered prior to chemotherapy on the same day. The recommended Imfinzi dose when administered with etoposide and either carboplatin or cisplatin is 1500 mg every 3 weeks prior to chemotherapy and then every 4 weeks as a single agent.

Horizon BCBSNJ Medical Policy Development Process:
This Horizon BCBSNJ Medical Policy (the “Medical Policy”) has been developed by Horizon BCBSNJ’s Medical Policy Committee (the “Committee”) consistent with generally accepted standards of medical practice, and reflects Horizon BCBSNJ’s view of the subject health care services, supplies or procedures, and in what circumstances they are deemed to be medically necessary or experimental/ investigational in nature. This Medical Policy also considers whether and to what degree the subject health care services, supplies or procedures are clinically appropriate, in terms of type, frequency, extent, site and duration and if they are considered effective for the illnesses, injuries or diseases discussed. Where relevant, this Medical Policy considers whether the subject health care services, supplies or procedures are being requested primarily for the convenience of the covered person or the health care provider. It may also consider whether the services, supplies or procedures are more costly than an alternative service or sequence of services, supplies or procedures that are at least as likely to produce equivalent therapeutic or diagnostic results as to the diagnosis or treatment of the relevant illness, injury or disease. In reaching its conclusion regarding what it considers to be the generally accepted standards of medical practice, the Committee reviews and considers the following: all credible scientific evidence published in peer-reviewed medical literature generally recognized by the relevant medical community, physician and health care provider specialty society recommendations, the views of physicians and health care providers practicing in relevant clinical areas (including, but not limited to, the prevailing opinion within the appropriate specialty) and any other relevant factor as determined by applicable State and Federal laws and regulations.
