Details and patient eligibility

About

The purpose of this study is to investigate whether the addition of panitumumab to radiotherapy plus gemcitabine will increase the number of patients who are alive and progression free at 7 months.

Full description

This is a phase I/II, multi-center dose escalation study.

Phase I:

Patients will be enrolled in cohorts of 3 per dose level until the MTD of panitumumab has been established.

Phase II:

Up to approximately 56 patients will be treated at the MTD level of panitumumab as established in the phase I part of the study.

Based on the historic data of patients with pancreatic cancer treated with gemcitabine based chemoradiation, we aim to increase the number of patients who are alive and progression free at 7 months from the historical value of 50% to 70% with the combination treatment of chemoradiation plus panitumumab.

Exclusion criteria

Participation in another therapeutic clinical study within 30 days of enrollment or during this clinical study.
No adequate radiation therapy possible: based on the opinion of the radiation oncologist when radiation therapy cannot be performed because radiation field is too large (PTV volume too large or OAR too high)
History of allergic reactions to gemcitabine or antibody treatment.
Presence of any serious concomitant systemic disorders incompatible with the clinical study (e.g. uncontrolled inter-current illness including ongoing or active infection, uncontrolled hypertension).
Clinically significant cardiovascular disease (including myocardial infarction, unstable angina, symptomatic congestive heart failure, serious uncontrolled cardiac arrhythmia) within 1 year before enrolment/randomization
History of interstitial lung disease e.g. pneumonitis or pulmonary fibrosis or evidence of interstitial lung disease on baseline chest CT scan
Presence of any significant central nervous system or psychiatric disorder(s) that would hamper the patient's compliance.
Pregnant or breastfeeding women.
Absence of adequate contraception for both male and female fertile patients for the duration of the study; and also for six months after last treatment.
Known positive status for HIV and/or hepatitis B or C.
Any reason why, in the investigator's opinion, the patient should not participate in the study.
Drug or alcohol abuse.
