BENEFIT APPLICATION

Subject to the terms and conditions of the applicable benefit contract, cetuximab (Erbitux) may be covered under the medical benefits of the Company’s products when medical necessity criteria and dosing and frequency requirements listed in this medical policy are met.

US FOOD AND DRUG ADMINISTRATION (FDA) STATUS

The FDA's approval of cetuximab (Erbitux) was initially issued on February 12, 2004. Supplemental approvals have since been issued.

PEDIATRIC USE

The safety and effectiveness of cetuximab (Erbitux) in pediatric individuals have not been established.

Description

Cetuximab (Erbitux) is a recombinant monoclonal antibody and an antineoplastic agent that works differently than standard chemotherapy or hormonal therapy. It also has been shown to enhance the antitumor effects of other chemotherapy. Monoclonal antibodies may be used to target and destroy certain cancer cells while causing little harm to normal cells. Cetuximab (Erbitux) binds to the extracellular domain of the human epidermal growth factor receptor (EGFR), which is expressed in many human cancers, including head and neck cancer and colon and rectum cancer. Cetuximab (Erbitux), by attaching itself to the EGFR of cancer cells, is able to prevent the receptors from being activated. Through various mechanisms, it is able to inhibit cell division, promote cell death, and inhibit angiogenesis and metastasis.

METASTATIC COLORECTAL CANCER

The US Food and Drug Administration (FDA) has issued several approvals for its use in metastatic colorectal cancer (mCRC). Cetuximab (Erbitux) received initial FDA approval in 2004 for the treatment of EGFR-expressing mCRC either in combination with irinotecan or as a single agent, when there is an intolerance to irinotecan. An FDA approval in 2008 expanded the use of cetuximab (Erbitux) as a single agent in mCRC after failure of both irinotecan-based and oxaliplatin-based chemotherapy. A more recent FDA approval, in 2012, allows for the use of cetuximab (Erbitux) in combination with FOLFIRI (irinotecan, 5-fluorouracil [5-FU], leucovorin) for first-line treatment of mCRC.

Cetuximab (Erbitux) therapy in mCRC is further guided by the status of the Kirsten rat sarcoma viral oncogene homolog (KRAS) gene and neuroblastoma RAS (NRAS) gene. When KRAS or NRAS mutations exist, the genes are said to be abnormal or mutated. When no mutations exist, KRAS/NRAS are said to be normal or wild-type (nonmutated). An FDA-approved test has been developed to determine the KRAS/NRAS mutation status of mCRC. The FDA, in addition to the National Comprehensive Cancer Network (NCCN), warns that analysis should be performed "in laboratories with demonstrated proficiency in the specific technology being utilized. Improper assay performance can lead to unreliable test results."

Van Cutsem et al. (2007, 2008) published literature detailing a clinical trial to evaluate the safety and efficacy of cetuximab (Erbitux) plus chemotherapy versus chemotherapy alone for individuals with untreated mCRC. The phase III multicenter study (NCT00154102) consisted of randomized, open-label, parallel assignment of individuals to receive either active treatment (cetuximab [Erbitux] 400 mg/m² as the initial dose followed by 250 mg/m² weekly for the duration of the study) with chemotherapy or chemotherapy alone until disease progression or toxicity developed. The chemotherapy consisted of FOLFIRI (5-fluorouracil [5-FU], leucovorin [LV], and irinotecan). A total of 1217 individuals were enrolled by the time of the 2007 publication with 608 assigned to receive active treatment with chemotherapy and 609 assigned to receive chemotherapy only. The primary endpoint was progression-free survival (PFS). Secondary endpoints included overall survival (OS), response rate (RR), duration of response (DOR), quality of life (QOL) measures, and safety measures. The median PFS for the active treatment arm was 8.9 months versus 8.1 months for the chemotherapy-only arm (p=0.0358). The median OS for the active treatment arm was 19.6 months versus 18.5 months for the chemotherapy-only arm. The RR for the active treatment arm was 46.9 percent versus 38.7 percent for the chemotherapy-only arm (p=0.005). The grade 3 or higher reactions did not differ significantly between the two arms except for skin reactions, infusion-related reactions, and diarrhea, which occurred in the active treatment arm more frequently than the chemotherapy-only arm.

Jonker et al. (2007) conducted a clinical trial to evaluate the safety and efficacy of cetuximab (Erbitux) plus best supportive care versus best supportive care (BSC) alone for individuals with epidermal growth factor receptor (EGFR)-positive mCRC. The phase III multicenter study (NCT00079066) consisted of randomized, open-label, parallel assignment of individuals to receive either active treatment (cetuximab [Erbitux] 400 mg/m² as the initial dose followed by 250 mg/m² weekly for the duration of the study) with BSC or BSC alone until disease progression or toxicity developed. A total of 572 individuals were enrolled with 287 assigned to receive active treatment with BSC and 285 assigned to receive BSC only. The primary endpoint was OS. Secondary endpoints included PFS, RR, QOL measures, and safety measures. The median OS for the active treatment arm was 6.1 months versus 4.6 months for the BSC-only arm (p=0.0046). The PFS was statistically higher in the active treatment arm versus the BSC arm (p<0.001). The RR was statistically higher in the active treatment arm versus the BSC arm (p<0.001).

HEAD AND NECK CANCERS

In 2006, the FDA issued a supplemental approval for the use of cetuximab (Erbitux) in certain types of locally or regionally advanced, recurrent, or metastatic squamous cell head and neck cancers, either as a single agent or in combination with radiation therapy. In 2011, cetuximab (Erbitux) was indicated for use in combination with platinum-based therapy with 5-FU for the first-line treatment of recurrent locoregional disease or metastatic squamous cell carcinoma of the head and neck.

Bonner et al. (2006) conducted a clinical trial to evaluate the safety and efficacy of cetuximab (Erbitux) plus radiation therapy (RT) versus RT alone for individuals with locoregionally advanced head and neck cancer. The phase III multicenter study (NCT00004227) consisted of randomized, open-labeled, parallel assignment of individuals to receive either active treatment (cetuximab [Erbitux] 400 mg/m² as the initial dose followed by 250 mg/m² weekly for the duration of the RT) with RT or RT alone. For both arms, the RT dose was further randomized to one of three groups: 1.) RT once daily 5 days a week for 3.5 weeks followed by RT twice daily 5 days a week for 2.5 weeks. 2.) RT once daily 5 days a week for 7 weeks. 3.) RT twice daily 5 days a week for 6 to 6.5 weeks. A total of 424 individuals were enrolled with 211 assigned to receive active treatment with RT and 213 assigned to receive RT only. The primary endpoint was the DOR. Secondary endpoints were OS, PFS, RR, and safety measures. The median DOR was 24.4 months for the active treatment arm versus 14.9 months for the RT-only arm (p=0.005). The median OS was 49.0 months for the active treatment arm versus 29.3 months for the RT only arm (p=0.03). The active treatment significantly prolonged PFS versus RT only (p=0.006). The incidence of grade 3 or higher reactions did not differ significantly between the active treatment arm versus RT only except for acneiform rash and transfusion reactions.

Vermorken et al. (2007) conducted a clinical trial to evaluate the safety and efficacy of cetuximab (Erbitux) plus platinum-based chemotherapy versus chemotherapy alone for individuals who had not received treatment for recurrent or metastatic head and neck cancer. The phase III multicenter study (NCT00122460) consisted of randomized, open-label, parallel assignment of individuals to receive either active treatment (cetuximab [Erbitux] 400 mg/m² as the initial dose followed by 250 mg/m² weekly for the duration of the study) with chemotherapy or chemotherapy alone for a maximum of six cycles. If an individual in the active treatment arm achieved stable disease, they were able to continue to receive cetuximab (Erbitux) until disease progression or toxicity developed. The chemotherapy consisted of 5-FU along with either cisplatin or carboplatin. A total of 442 individuals were enrolled, with 222 assigned to receive active treatment with chemotherapy and 220 assigned to receive chemotherapy only. The primary endpoint was OS. Secondary endpoints included PFS, RR, disease control, time to treatment failure, DOR, QOL measures, and safety measures. The median OS was 10.1 months for the active treatment arm versus 7.4 months for the chemotherapy-only arm (p=0.04). The median PFS was 5.6 months for the active treatment arm versus 3.3 months for the chemotherapy-only arm (p<0.001). The RR for the active treatment arm was 36 percent versus 20 percent for the chemotherapy-only arm (p<0.001). The incidence of grade 3 or 4 adverse events was similar in both arms except for the rate of sepsis in the active treatment arm.
