IMC-A12 10 milligrams per kilogram (mg/kg) over one hour every two weeks. A cycle is defined as four weeks of therapy. Participants will continue on study until evidence of progressive disease, or unacceptable toxicity develops.

IMC-A12 (cixutumumab)

IMC-A12 10 mg/kg over one hour followed by cetuximab 500 milligrams per square meter (mg/m\^2) over two hours. This sequence will be repeated every two weeks. Participants will continue on study until evidence of progressive disease or unacceptable toxicity develops.

cetuximab (Erbitux ®)

Call 1-877-CTLILLY (1-877-285-4559) or 1-317-615-4559 Mon - Fri 9 AM - 5 PM Eastern time (UTC/GMT - 5 hours, EST)

The purpose of this study is to determine if IMC-A12 alone or in combination with Cetuximab (Erbitux®) can increase the time prior to disease progression in participants with Squamous Cell Head and Neck Cancer who have had disease progression and platinum-containing chemotherapeutic regimen.

The routine cancer treatments for Squamous Cell Carcinoma Head and Neck Cancer have improved but still leave a percentage of participants with incurable disease. New alternatives for participants whose disease is refractory to existing therapies is needed.

IMC-A12 is a monoclonal antibody which binds to special receptors known as insulin-like growth factor-I receptor (IGF-IR). This binding action has been shown to inhibit the growth of a variety of human tumor cell lines.

The purpose of this study is to evaluate the effects of IMC-A12 by itself or with Cetuximab (Erbitux®) in participants with Squamous Cell Carcinoma Head and Neck Cancer that has spread to other parts of the body, and to determine how long the drug remains in the body. The study will also look at what side effects IMC-A12 may cause when a participant is receiving treatment.

Study of IMC-A12, Alone or in Combination With Cetuximab, in Participants With Recurrent or Metastatic Squamous Cell Carcinoma (MSCC) of the Head and Neck

A Randomized Phase 2 Open-Label Study of IMC-A12, as a Single Agent or in Combination With Cetuximab, in Patients With Recurrent or Metastatic Squamous Cell Carcinoma of the Head and Neck and Disease Progression on Prior Platinum-Based Chemotherapy

PFS was defined as the interval from randomization until PD or death, whichever occurred first. Response was defined using Response Evaluation Criteria in Solid Tumors (RECIST, version 1.0) criteria. PD was defined as having at least a 20% increase in sum of the longest diameter of target lesions or the appearance of new lesions. PFS was censored at the date of the last objective progression-free disease assessment for participants who did not experience PD or death.

ORR was defined as the percentage of participants achieving either CR or PR. Response was defined using RECIST, version 1.0 criteria. CR was defined as the disappearance of all target lesions. PR was defined as having at least a 30% decrease in sum of longest diameter of target lesions. Percentage of participants is calculated as a total number of participants with CR or PR divided by the total number of participants treated then multiplied by 100.

PFS at 6 months was defined as the percentage of participants who have neither experienced PD nor died at 6 months after the date of randomization. Response was defined using RECIST, version 1.0 criteria. PD was defined as having at least a 20% increase in sum of the longest diameter of target lesions or the appearance of new lesions. Percentage of participants is calculated as the total number of participants with PFS at 6 months divided by the total number of participants treated then multiplied by 100.

OS was defined as the duration from the date of randomization to the date of death from any cause. For participants who were alive, OS was censored at the date of last follow-up visit or at the date of last contact.

The duration of CR or PR was defined as the time from first objective status assessment of CR or PR to the first time of PD or death. Response was defined using RECIST, version 1.0 criteria. CR was defined as the disappearance of all target lesions. PR was defined as having at least a 30% decrease in sum of longest diameter of target lesions. Duration of response was censored on the date of last tumor assessment for participants who were alive and have no evidence of PD.

TEAEs were defined as serious and other non-serious adverse events (AEs) that occurred or worsened after study treatment (regardless of causality). Data presented are the number of participants who experienced TEAEs including serious TEAEs, and deaths during the study including the 30-day follow-up. A summary of serious and other non-serious AEs regardless of causality is located in the Reported Adverse Events section of this report.

No data for biomarkers and serum antibodies were collected due to lack of an appropriate validated assay.

IMC-A12 (cixutumumab) 10 mg/kg dose administered as an IV infusion over a period of 1 hour once every 2 weeks. A cycle was defined as 4 weeks of therapy (4-week cycle). Treatment was continued until there was evidence of PD, unacceptable toxicity, or withdrawal of consent.

IMC-A12 (Cixutumumab)

IMC-A12 (cixutumumab) 10 mg/kg dose administered as an IV infusion over a period of 1 hour followed by cetuximab 500 mg/m\^2 dose administered as an IV infusion over a period of 2 hours; this sequence was repeated once every 2 weeks (4-week cycle). Treatment was continued until there was evidence of PD, unacceptable toxicity, or withdrawal of consent.

ECOG performance status was used to classify participants according to their functional impairment. Score 0 = Fully active, able to carry on all pre-disease performance without restriction. Score 1 = Restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature, for example, light house work, office work. Score 2 = Ambulatory and capable of all self-care but unable to carry out any work activities; up and about more than 50% of waking hours.
