Phase phase 2
Target EGFR
Sponsor WiSP Wissenschaftlicher Service Pharma GmbH
Collaborator Gesellschaft fur Medizinische Innovation – Hamatologie und Onkologie mbH
Start date December 2010
End date January 2016
Trial size 59 participants
Trial identifier NCT01257360, 2009-016782-28, GMIHO 009/2009, WISP_AG52


The objective of this trial is to obtain evidence that, in patients with RAS wildtype tumors, a chemotherapy-free combined modality treatment with panitumumab is clearly superior to radiotherapy alone and achieves a pCR rate comparable to that after radiochemotherapy including two-drug combinations while reducing the toxicity compared to these two-drug regimens.

Eligibility Criteria

Male or female participants at least 18 years old.

Inclusion Criteria: - Histologically confirmed diagnosis of locally advanced rectal cancer (stage II or III) localised 0 - 12 cm ab ano as measured by rigid rectoscopy (i.e. lower and middle third of the rectum) - Staging requirements: trans-rectal endoscopic ultrasound (EUS) and magnetic resonance imaging (MRI) - Sufficient representative sample material for RAS analysis - Wild-type RAS (determined by an accredited local laboratory, if not available by pathology of Mannheim university) - RAS wild-type tested in - KRAS exon 2 (codons 12/13) - KRAS exon 3 (codons 59/61) - KRAS exon 4 (codons 117/146) - NRAS exon 2 (codons 12/13) - NRAS exon 3 (codons 59/61) - NRAS exon 4 (codons 117/146) - Informed consent of the patient - Aged at least 18 years - WHO Performance Status 0-2 - Life expectancy of al least 12 weeks - Adequate haematological, hepatic, renal and metabolic function parameters: - Leukocytes > 3000/mm³ - ANC ≥ 1500/mm³ - Platelets ≥ 100,000/mm³ - Hb > 9 g/dl - Creatinine clearance ≥ 50 ml/min and serum creatinine ≤ 1.5 x upper limit of normal - Bilirubin ≤ 1.5 x upper limit of normal - GOT-GPT ≤ 2.5 x upper limit of normal - AP ≤ 5 x upper limit of normal - Magnesium ≥ lower limit of normal - Calcium ≥ lower limit of normal Exclusion Criteria: - Lower border of the tumor localised more than 12 cm ab ano as measured by rigid rectoscopy - Distant metastases (to be excluded by CT scan of the thorax and abdomen) - cT4 tumor (as determined by MRI and/or endorectal ultrasound) - Risk of tumor involvement of the circumferential resection margin, according to the MRI assessment - Sphincter sparing is the major reason for choosing the neoadjuvant treatment approach - Prior antineoplastic therapy for rectal cancer - Prior radiotherapy of the pelvic region - Major surgery within the last 4 weeks prior to inclusion - Subject pregnant or breast feeding, or planning to become pregnant within 6 months after the end of treatment - Subject (male or female) is not willing to use highly effective methods of contraception (per institutional standard) during treatment and for 6 months (male or female) after the end of treatment (adequate: oral contraceptives, intrauterine device or barrier method in conjunction with spermicidal jelly) - Serious concurrent diseases - On-treatment participation in a clinical study in the period 30 days prior to inclusion - Clinically significant cardiovascular disease in (incl. myocardial infarction, unstable angina, symptomatic congestive heart failure, serious uncontrolled cardiac arrhythmia) ≤ 1 year before enrolment - History of interstitial lung disease, e.g. pneumonitis or pulmonary fibrosis or evidence of interstitial lung disease on baseline chest CT scan - History of HIV infection - Prior or concurrent malignancy (≤ 5 years prior to enrolment in study) except non-melanoma skin cancer or cervical carcinoma FIGO stage 0-1 if the patient is continuously disease-free - Known allergic reactions on study medication
