All eligible subjects will receive cetuximab treatment only during week 1 of the treatment course and concomitant cetuximab and boost radiotherapy (RT) during week two to week seven of the treatment course

Cetuximab 400 milligram/square meter (mg/m\^2) intravenous (IV) infusion over 120 minutes for 1 week, subsequently followed by 250 mg/m\^2 IV infusion over 60 minutes, from week 2 to 7 along with concomitant boost radiotherapy: 72.0 Gray (Gy) total for 42 fractions in 6 weeks, initially

* Once-daily fractions: 32.4 Gy in 18 fractions of 1.8 Gy for 3.6 weeks (5 fractions/week), followed by
* Twice-daily fractions 39.6 Gy in 24 fractions for 2.4 weeks: morning dose 1.8 Gy/fraction for a total of 12 fractions 5 fractions/week; evening dose 1.5 Gy/fraction for a total of 12 fractions 5 fractions/week. Doses are separated by at least a 6-hour interval

Primary objective: to assess the antitumor activity and safety profile of cetuximab when given in combination with radiotherapy (RT) for the treatment of locally advanced squamous cell carcinoma of the head and neck (SCCHN) in Chinese subjects.

Secondary objective: to assess the pharmacokinetic (PK) profile and immunogenicity of cetuximab in Chinese subjects.

Further objective: to identify for cetuximab potential predictive biomarkers of response and safety.

Cetuximab With Radiotherapy for Locally Advanced Squamous Cell Carcinoma of the Head and Neck in Chinese Subjects

Open-label, Single-arm, Multicenter, Phase III Trial to Assess the Antitumor Activity and Safety of Cetuximab When Given in Combination With Radiotherapy for the Treatment of Locally Advanced Squamous Cell Carcinoma of the Head and Neck in Chinese Subjects

Best overall (objective) response was defined as the occurrence of complete response (CR) or partial response (PR) based on the investigator's assessment according to modified World Health Organization (WHO) criteria confirmed at a repeat assessment performed no less than 28 days after the criteria for response were first met. CR was defined as disappearance of all index lesions. PR was defined as a 50% or more decrease in the sum of the products of diameters (SOPD) of index lesions compared to the baseline SOPD, with no evidence of PD.

Progression-free survival was defined as the duration (in months) from first administration of trial treatment to first observation of PD (radiological or clinical, if radiological PD is not available), or death due to any cause. The PFS time of participants without observation of PD but death occurring after two or more missed consecutive tumor assessments (i.e. two-fold scheduled time interval of two consecutive tumor assessments) was censored on the date of last tumor assessment or first administration of trial treatment (whichever was later).

An adverse event (AE) was defined as any untoward medical occurrence in the form of signs, symptoms, abnormal laboratory findings, or diseases that emerges or worsens relative to baseline during a clinical study with an IMP, regardless of causal relationship and even if no IMP has been administered.

Participants received cetuximab 400 milligram/square meter (mg/m\^2) intravenous (IV) infusion over 120 minutes for 1 week, subsequently followed by 250 mg/m\^2 IV infusion over 60 minutes, from week 2 to 7 along with concomitant boost radiotherapy: 72.0 Gray (Gy) total for 42 fractions in 6 weeks, initially, once-daily fractions: 32.4 Gy in 18 fractions of 1.8 Gy for 3.6 weeks (5 fractions/week), followed by twice-daily fractions 39.6 Gy in 24 fractions for 2.4 weeks: morning dose 1.8 Gy/fraction for a total of 12 fractions 5 fractions/week; evening dose 1.5 Gy/fraction for a total of 12 fractions 5 fractions/week. Doses were separated by at least a 6-hour interval. Treatment emergent phase, i.e. treatment-emergent adverse events (TEAEs, adverse events which occur or worsen on the first dosing day of trial treatment and until 60 days after the last trial treatment administration (cetuximab or radiotherapy).

Cetuximab: Treatment Emergent Phase

Participants received cetuximab 400 milligram/square meter (mg/m\^2) intravenous (IV) infusion over 120 minutes for 1 week, subsequently followed by 250 mg/m\^2 IV infusion over 60 minutes, from week 2 to 7 along with concomitant boost radiotherapy: 72.0 Gray (Gy) total for 42 fractions in 6 weeks, initially, once-daily fractions: 32.4 Gy in 18 fractions of 1.8 Gy for 3.6 weeks (5 fractions/week), followed by twice-daily fractions 39.6 Gy in 24 fractions for 2.4 weeks: morning dose 1.8 Gy/fraction for a total of 12 fractions 5 fractions/week; evening dose 1.5 Gy/fraction for a total of 12 fractions 5 fractions/week. Doses were separated by at least a 6-hour interval. Late phase, i.e. adverse events which occur or worsen more than 60 days after the last trial treatment administration (cetuximab or radiotherapy), and before end of trial.

Cetuximab: Late Phase

Participants received cetuximab 400 milligram/square meter (mg/m\^2) intravenous (IV) infusion over 120 minutes for 1 week, subsequently followed by 250 mg/m\^2 IV infusion over 60 minutes, from week 2 to 7 along with concomitant boost radiotherapy (RT): 72.0 Gray (Gy) total for 42 fractions in 6 weeks, initially, once-daily fractions: 32.4 Gy in 18 fractions of 1.8 Gy for 3.6 weeks (5 fractions/week), followed by twice-daily fractions 39.6 Gy in 24 fractions for 2.4 weeks: morning dose 1.8 Gy/fraction for a total of 12 fractions 5 fractions/week; evening dose 1.5 Gy/fraction for a total of 12 fractions 5 fractions/week. Doses were separated by at least a 6-hour interval.
