E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine the efficacy of panitumumab plus the cisplatin/gemcitabine combination chemotherapy in k-ras wildtype in patients with cholangiocarcinoma / gallbladder carcinoma, compared to the historical data for the same chemotherapy, which are verified by a randomised control group without the antibody. |
|
E.2.2 | Secondary objectives of the trial |
Response rate (RR) within 48 weeks of treatment, progression-free survival (PFS), overall survival (OS), safety: explorative evaluation in relation to the findings in the reference arm with respect to efficacy and toxicity, translational research: correlation of tumor response with KRAS, PTEn and B-Raf alterations. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Signed and dated informed consent before the start of specific protocol procedures.
Histologically or cytologically documented diagnosis of cholangiocarcinoma or gall bladder carcinoma
Presence of at least one measurable site of disease following RECIST V. 1.1 criteria
Wild-type KRAS status as assessed by standardized PCR
Unresectable, locally advanced or metastatic disease
Age > 18 years.

Life expectancy of at least 12 weeks.
Adequate bone marrow, liver (with stenting for any obstruction, if required) and renal function as assessed by the following laboratory requirements to be conducted within 7 days prior to screening:
-Hemoglobin > 10.0 g/dl
-Leukocyte count >3.000/mm3 ; absolute neutrophil count (ANC) >1.500/mm3
-Platelet count >= 100.000/mm³
-Total bilirubin < 5,0 times the upper limit of normal
-ALT and AST < 3 x upper limit of normal
-Alkaline phosphatase < 5 x ULN
-PT-INR/PTT < 1.5 x upper limit of normal [Patients who are being therapeutically anticoagulated with an agent such as coumarin or heparin will be allowed to participate provided that no prior evidence of underlying abnormality in these parameters exists.]
-Serum creatinine < 1.5 x upper limit of normal and creatinine clearance > 60 ml/min.
-Magnesium ≥ lower limit of normal; calcium ≥ lower limit of normal
The patient is willing and able to comply with the protocol for the duration of the study, including hospital visits for treatment and scheduled follow-up visits and examinations.
Negative pregnancy test performed within 7 days of the start of treatment, and willingness 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).

E.5 End points |
E.5.1 | Primary end point(s) |
The primary objective of the study is to determine the efficacy of panitumumab plus cisplatin/gemcitabine (CisGem) combination chemotherapy in KRAS wild-type biliary tract cancer patients without systemic pre-treatment, compared to the historical data for standard CisGem chemotherapy, which are verified by a randomised control group without the antibody. The primary endpoint is the progression-free survival rate after 6 months, based on the ITT population. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
6 months after trial inclusion |
|
E.5.2 | Secondary end point(s) |
Secondary endpoints to be analyzed in both study arms (including exploratory comparisons) are:
Tumor response according to RECIST criteria within the first 48 weeks of treatment
Progression-free survival (PFS)
Overall survival (OS)
Toxicity/safety
Translational: assessment/correlation of tumor response with KRAS (mandatory), EGFR, PTEN and BRAF (all 3 optional in the scope of the translational research) alterations in cholangiocarcinomas and gallbladder cancer.
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Tumor response within the first 48 weeks of treatment
PFS, OS on event
Toxicity/safety after end of therapy
Translational correlation on response evaluation
