Adverse reactions
6 ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the label: Infusion reactions [see Warnings and Precautions (5.1)]. Cardiopulmonary arrest [see Warnings and Precautions (5.2)]. Pulmonary toxicity [see Warnings and Precautions (5.3)]. Dermatologic toxicity [see Warnings and Precautions (5.4)]. Hypomagnesemia and Electrolyte Abnormalities [see Warnings and Precautions (5.6)]. The most common adverse reactions (incidence ≥25%) are: cutaneous adverse reactions (including rash, pruritus, and nail changes), headache, diarrhea, and infection. (6) To report SUSPECTED ADVERSE REACTIONS, contact Eli Lilly and Company at 1-800-LillyRx (1-800-545-5979) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience 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 data described in Warnings and Precautions reflect exposure to ERBITUX in 1373 patients with SCCHN or CRC enrolled in clinical trials and treated at the recommended dosage for a median of 7 to 14 weeks [see Clinical Studies (14)]. The most common adverse reactions in ERBITUX clinical trials (incidence ≥25%) include cutaneous adverse reactions (including rash, pruritus, and nail changes), headache, diarrhea, and infection. Squamous Cell Carcinoma of the Head and Neck (SCCHN) In Combination with Radiation Therapy The safety of ERBITUX in combination with radiation therapy compared to radiation therapy alone was evaluated in BONNER. The data described below reflect exposure to ERBITUX in 420 patients with locally or regionally advanced SCCHN. ERBITUX was administered at the recommended dosage (400 mg/m2 initial dose, followed by 250 mg/m2 weekly). Patients received a median of 8 infusions (range 1 to 11) [see Clinical Studies (14.1)]. Table 2 provides the frequency and severity of adverse reactions in BONNER. Table 2: Selected Adverse Reactions in ≥10% of Patients with Locoregionally Advanced SCCHN (BONNER)a Adverse Reaction ERBITUX with Radiation (n=208) Radiation Therapy Alone (n=212) Grades 1–4 b Grades 3 and 4 Grades 1–4 Grades 3 and 4 a Adverse reactions occurring in ≥10% of patients in the ERBITUX combination arm and at a higher incidence (≥5%) compared to the radiation alone arm. b Adverse reactions were graded using the NCI CTC, version 2.0. c Includes cases also reported as infusion reaction. d Infusion reaction defined as any event described at any time during the clinical study as “allergic reaction” or “anaphylactoid reaction”, or any event occurring on the first day of dosing described as “allergic reaction”, “anaphylactoid reaction”, “fever”, “chills”, “chills and fever”, or “dyspnea”. e Based on laboratory measurements, not on reported adverse reactions, the number of subjects with tested samples varied from 205–206 for ERBITUX with Radiation arm; 209–210 for Radiation alone. f Acneiform rash defined as any event described as “acne”, “rash”, “maculopapular rash”, “pustular rash”, “dry skin”, or “exfoliative dermatitis”.

The following sites were affected: salivary glands (65% versus 56%), larynx (52% versus 36%), subcutaneous tissue (49% versus 45%), mucous membrane (48% versus 39%), esophagus (44% versus 35%), skin (42% versus 33%). The incidence of Grade 3 or 4 late radiation toxicities was similar between the radiation therapy alone and the ERBITUX with radiation treatment groups. In Combination with Platinum-based Therapy and Fluorouracil The safety of a cetuximab product in combination with platinum-based therapy and fluorouracil or platinum-based therapy and fluorouracil alone was evaluated in EXTREME. The data described below reflect exposure to a cetuximab product in 434 patients with recurrent locoregional disease or metastatic SCCHN. Because ERBITUX provides approximately 22% higher exposure relative to the cetuximab product, the data provided below may underestimate the incidence and severity of adverse reactions anticipated with ERBITUX for this indication; however, the tolerability of the recommended dose is supported by safety data from additional studies of ERBITUX [see Clinical Pharmacology (12.3)]. Cetuximab was administered intravenously at a dosage of 400 mg/m2 for the initial dose, followed by 250 mg/m2 weekly. Patients received a median of 17 infusions (range 1 to 89) [see Clinical Studies (14.1)]. Table 3 provides the frequency and severity of adverse reactions in EXTREME. Table 3: Selected Adverse Reactions in ≥10% of Patients with Recurrent Locoregional Disease or Metastatic SCCHN (EXTREME)a Adverse Reaction Cetuximab with Platinum-based Therapy and fluorouracil (n=219) Platinum-based Therapy and fluorouracil Alone (n=215) Grades 1–4 b Grades 3 and 4 Grades 1–4 Grades 3 and 4 a Adverse reactions occurring in ≥10% of patients in the cetuximab combination arm and at a higher incidence (≥5%) compared to the platinum-based therapy and fluorouracil alone arm. b Adverse reactions were graded using the NCI CTC, version 2.0. c Infusion reaction defined as “anaphylactic reaction”, “hypersensitivity”, “fever and/or chills”, “dyspnea”, or “pyrexia” on the first day of dosing. d Infection excludes sepsis-related events which are presented separately. e Acneiform rash defined as “acne”, “dermatitis acneiform”, “dry skin”, “exfoliative rash”, “rash”, “rash erythematous”, “rash macular”, “rash papular”, or “rash pustular”.

The majority of these events occurred in patients who received cisplatin and fluorouracil with or without cetuximab. Cardiac disorders were observed in 11% and 12% of patients who received cisplatin and fluorouracil with or without cetuximab, respectively, and 6% and 4% in patients who received carboplatin and fluorouracil with or without cetuximab, respectively. In both arms, the incidence of cardiovascular events was higher in the cisplatin and fluorouracil containing subgroup. Death attributed to cardiovascular events or sudden death was reported in 3% of the patients in the cetuximab with platinum-based therapy and fluorouracil arm and in 2% of the patients in the platinum-based therapy and fluorouracil alone arm. K-Ras Wild-type, EGFR-expressing, Metastatic Colorectal Cancer (mCRC) In Combination with FOLFIRI The safety of a cetuximab product in combination with FOLFIRI or FOLFIRI alone was evaluated in CRYSTAL. The data described below reflect exposure to a cetuximab product in 667 patients with K-Ras wild-type, EGFR-expressing, mCRC. ERBITUX provides approximately 22% higher exposure compared to this product; however, the safety data from CRYSTAL is consistent in incidence and severity of adverse reactions with those seen for ERBITUX in this indication. Cetuximab was administered intravenously at a dosage of 400 mg/m2 initial dose, followed by 250 mg/m2 weekly. Patients received a median of 24 infusions (range 1 to 224) [see Clinical Studies (14.2)]. Table 4 provides the frequency and severity of adverse reactions in CRYSTAL. Table 4: Selected Adverse Reactions in ≥10% of Patients with K-Ras Wild-type and EGFR-expressing, Metastatic Colorectal Cancer (CRYSTAL)a Adverse Reaction Cetuximab with FOLFIRI (n=317) FOLFIRI Alone (n=350) Grades 1–4 b Grades 3 and 4 Grades 1–4 Grades 3 and 4 a Adverse reactions occurring in ≥10% of patients in the cetuximab combination arm and at a higher incidence (≥5%) compared to the FOLFIRI alone arm. b Adverse reactions were graded using the NCI CTC, version 2.0. c Infusion reaction defined as any event meeting the medical concepts of allergy/anaphylaxis at any time during the clinical study or any event occurring on the first day of dosing and meeting the medical concepts of dyspnea and fever or by the following events: “acute myocardial infarction”, “angina pectoris”, “angioedema”, “autonomic seizure”, “blood pressure abnormal”, “blood pressure decreased”, “blood pressure increased”, “cardiac failure”, “cardiopulmonary failure”, “cardiovascular insufficiency”, “clonus”, “convulsion”, “coronary no-reflow phenomenon”, “epilepsy”, “hypertension”, “hypertensive crisis”, “hypertensive emergency”, “hypotension”, “infusion related reaction”, “loss of consciousness”, “myocardial infarction”, “myocardial ischemia”, “prinzmetal angina”, “shock”, “sudden death”, “syncope”, or “systolic hypertension”. d Acne-like rash defined by the following events: “acne”, “acne pustular”, “butterfly rash”, “dermatitis acneiform”, “drug rash with eosinophilia and systemic symptoms”, “dry skin”, “erythema”, “exfoliative rash”, “folliculitis”, “genital rash”, “mucocutaneous rash”, “pruritus”, “rash”, “rash erythematous”, “rash follicular”, “rash generalized”, “rash macular”, “rash maculopapular”, “rash maculovesicular”, “rash morbilliform”, “rash papular”, “rash papulosquamous”, “rash pruritic”, “rash pustular”, “rash rubelliform”, “rash scarlatiniform”, “rash vesicular”, “skin exfoliation”, “skin hyperpigmentation”, “skin plaque”, “telangiectasia”, or “xerosis”.

The data described below reflect exposure to ERBITUX in 242 patients with K-Ras wild-type, EGFR-expressing, metastatic colorectal cancer (mCRC) [see Warnings and Precautions (5.8)]. ERBITUX was administered intravenously at the recommended dosage (400 mg/m2 initial dose, followed by 250 mg/m2 weekly). Patients received a median of 17 infusions (range 1 to 51) [see Clinical Studies (14.2)]. Table 5 provides the frequency and severity of adverse reactions in Study CA225-025.

The most common adverse reactions were acneiform rash (88%), asthenia/malaise (73%), diarrhea (72%), and nausea (55%). The most common Grades 3–4 adverse reactions included diarrhea (22%), leukopenia (17%), asthenia/malaise (16%), and acneiform rash (14%). 6.2 Immunogenicity As with all therapeutic proteins, there is potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to cetuximab in the studies below with the incidence of antibodies to cetuximab in other studies or to other products may be misleading. An ELISA methodology was used to characterize the incidence of anti-cetuximab antibodies. The incidence of anti-cetuximab binding antibodies in 105 patients (from studies I4E-MC-JXBA, I4E-MC-JXBB, and I4E-MC-JXBD) with at least one post-baseline blood sample (≥4 weeks post first ERBITUX administration) was <5%. 6.3 Postmarketing Experience The following adverse reactions have been identified during post approval use of ERBITUX. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Neurologic: Aseptic meningitis Gastrointestinal: Mucosal inflammation Dermatologic: Stevens-Johnson syndrome, toxic epidermal necrolysis, life-threatening and fatal bullous mucocutaneous disease

Use in special populations
8 USE IN SPECIFIC POPULATIONS Lactation: Advise not to breastfeed. (8.2) 8.1 Pregnancy Risk Summary Based on findings from animal studies and its mechanism of action [see Clinical Pharmacology (12.1)], ERBITUX can cause fetal harm when administered to a pregnant woman. There are no available data for ERBITUX exposure in pregnant women. In an animal reproduction study, intravenous administration of cetuximab once weekly to pregnant cynomolgus monkeys during the period of organogenesis resulted in an increased incidence of embryolethality and abortion. Disruption or depletion of EGFR in animal models results in impairment of embryo-fetal development including effects on placental, lung, cardiac, skin, and neural development (see Data). Human IgG is known to cross the placental barrier; therefore, cetuximab may be transmitted from the mother to the developing fetus. Advise pregnant women of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20% respectively. Data Animal Data Pregnant cynomolgus monkeys were administered cetuximab intravenously once weekly during the period of organogenesis (gestation day [GD] 20-48) at dose levels 0.4 to 4 times the recommended dose of ERBITUX based on body surface area (BSA). Cetuximab was detected in the amniotic fluid and in the serum of embryos from treated dams on GD 49. While no fetal malformations occurred in offspring, there was an increased incidence of embryolethality and abortions at doses approximately 1 to 4 times the recommended dose of ERBITUX based on BSA. In mice, EGFR is critically important in reproductive and developmental processes including blastocyst implantation, placental development, and embryo-fetal/postnatal survival and development. Reduction or elimination of embryo-fetal or maternal EGFR signaling can prevent implantation, can cause embryo-fetal loss during various stages of gestation (through effects on placental development), and can cause developmental anomalies and early death in surviving fetuses. Adverse developmental outcomes were observed in multiple organs in embryos/neonates of mice with disrupted EGFR signaling. 8.2 Lactation Risk Summary There is no information regarding the presence of ERBITUX in human milk, the effects on the breastfed infant, or the effects on milk production. Human IgG antibodies can be excreted in human milk. Due to the potential for serious adverse reactions in breastfed infants from ERBITUX, advise women not to breastfeed during treatment with ERBITUX and for 2 months after the last dose of ERBITUX. 8.3 Females and Males of Reproductive Potential Pregnancy Testing Verify pregnancy status in females of reproductive potential prior to initiating ERBITUX [see Use in Specific Population (8.1)]. Contraception Based on its mechanism of action, ERBITUX can cause harm to the fetus when administered to a pregnant woman [see Use in Specific Populations (8.1)]. Females Advise females of reproductive potential to use effective contraception during treatment with ERBITUX and for 2 months after the last dose of ERBITUX. Infertility Females Based on animal studies, ERBITUX may impair fertility in females of reproductive potential [see Nonclinical Toxicology (13.1)]. 8.4 Pediatric Use The safety and effectiveness of ERBITUX in pediatric patients have not been established. The pharmacokinetics of cetuximab, in combination with irinotecan, were evaluated in pediatric patients with refractory solid tumors in an open-label, single-arm, dose-finding study. ERBITUX was administered once-weekly, at doses up to 250 mg/m2, to 27 patients ranging from 1 to 12 years old; and in 19 patients ranging from 13 to 18 years old. No new safety signals were identified in pediatric patients. The pharmacokinetics of cetuximab between the two age groups were similar following a single dose of 75 mg/m2 and 150 mg/m2. The volume of the distribution appears to be independent of dose and approximates the vascular space of 2 L/m2 to 3 L/m2. Following a single dose of 250 mg/m2, the mean AUC0-inf (CV%) was 17.7 mg*h/mL (34%) in the younger age group (1–12 years, n=9) and 13.4 mg*h/mL (38%) in the adolescent group (13–18 years, n=6). The mean half-life of cetuximab was 110 hours (69 to 188 hours) in the younger group and 82 hours (55 to 117 hours) in the adolescent group. 8.5 Geriatric Use Of the 1662 patients with advanced colorectal cancer who received ERBITUX with irinotecan, with FOLFIRI or as monotherapy in six studies (BOND, IMCL-CP02-9923, IMCL-CP02-0141, IMCL-CP02-0144, CA225-025 and CRYSTAL), 35% of patients were 65 years of age or older. No overall differences in safety or efficacy were observed between these patients and younger patients. Clinical studies of ERBITUX conducted in patients with head and neck cancer did not include sufficient number of subjects aged 65 and over to determine whether they respond differently from younger subjects.
