- Prior to enrolment subjects must have ErbB1 over-expression determined by immunohistochemistry (IHC) 3+ as assessed by a central laboratory;
- Subjects with stage III and IVA/IVB disease, who are to receive cisplatin chemotherapy and radiation therapy as primary treatment (total dose 65
- 70 Gy); Subjects with any Tis, T1 or T2 disease regardless of N stage, are excluded. Subjects with distant metastases, ie Stage IVC, are excluded.
- Willing and able to have a tumour biopsy taken at screening; For patients who have had prior tumour biopsy, an adequate archived specimen must be available.
- Male or female ≥18 years of age; Criteria for female subjects or female partners of male subjects: Non-child-bearing potential (i.e., women with functioning ovaries who have a GM2005/00448/00 CONFIDENTIAL EGF105884 22 current documented tubal ligation or hysterectomy, or women who are postmenopausal); Child-bearing potential (i.e., women with functioning ovaries and no documented impairment of oviductal or uterine function that would cause sterility.) This category includes women with oligomenorrhoea (severe), women who are perimenopausal, and young women who have begun to menstruate. These subjects must have a negative serum pregnancy test at screening and agree to one of the following: Complete abstinence from intercourse from 2 weeks prior to administration of the first dose of study medication until 28 days after the final dose of study medication; or Consistent and correct use of one of the following acceptable methods of birth control: male partner who is sterile prior to the female subject's entry into the study and is the sole sexual partner for that female subject; implants of levonorgestrel; injectable progestogen; any intrauterine device (IUD) with a documented failure rate of less than 1% per year; oral contraceptives (either combined or progestogen only); or barrier methods, including diaphragm or condom with a spermicide.
- ECOG performance status 0, 1 or 2;
- Subjects must have adequate haematological, renal and hepatic function; Calculated creatinine clearance ≥50 ml/min as determined by the modified method of Cockcroft and Gault or by the EDTA method. Absolute neutrophil count ≥1,500/μl, platelets ≥100,000/μl. Haemoglobin ≥9gm/dL (5mmol/L). Aspartate (AST) and alanine transaminase (ALT) less than 4 times the upper limit of the normal range (ULN).
