Open, Randomized Phase II Trial to Investigate the Efficacy and Safety of the PLK-1 Inhibitor BI 2536 in Patients With Advanced, Unresectable Pancreatic Cancer

The trial is conducted in order to evaluate the efficacy, safety and pharmacokinetics of BI 2536 in the treatment of unresectable advanced pancreatic cancer as first line or second line therapy. A secondary aim is to identify the most suitable dosage regimen for the further phase II and III clinical programme of BI 2536. To achieve this objective, two dosage regimens are compared in patients receiving first line therapy.


Eligibility Criteria:
Inclusion Criteria:

1. male or female patient aged 18 years or older
2. patient with confirmed diagnosis of unresectable, either locally advanced or metastatic, ductal adenocarcinoma of the pancreas
3. patient who is either chemonaïve (for the first line cohorts), or who presents with progressive disease under first line chemotherapy with a gemcitabine based regimen (for the second line cohort)
4. Karnofsky performance status of ¿ 70% for the first line cohorts, and Karnofsky performance status ¿ 50% for the second line cohort
5. patient with at least one measurable tumour lesion that can accurately be measured by magnetic resonance imaging (MRI), or computed tomography (CT) in at least one dimension (longest diameter to be recorded)
6. life expectancy of at least three months
7. patient must have given written informed consent consistent with the guidelines of the international conference on harmonisation for good clinical practice (ICH-GCP) as well as with local legislation

Exclusion Criteria:

1. prior adjuvant chemotherapy (for first line cohorts only)
2. ampullary carcinoma of the pancreas
3. hypersensitivity to the trial drug or the excipients
4. persistence of toxicities of prior anti cancer therapies which are deemed to be clinically relevant
5. known second malignancy requiring therapy
6. brain metastases which are symptomatic or require therapy
7. absolute neutrophil count less than 1.500/mm3
8. platelet count less than 100.000/mm3
