E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy of Capecitabine in combination with Lapatinib, in terms of overall survival, in the first line treatment of patients with metastatic Pancreatic cancer.
|
|
E.2.2 | Secondary objectives of the trial |
To evaluate: • Progression-free survival • Overall response rate (complete and partial responses) • Clinical benefit (complete response, partial response or stable disease for at least 6 months) • the qualitative and quantitative toxicity associated with Lapatinib administered with Capecitabine to patients with metastatic pancreatic cancer. • For patients where sufficient tumour samples are available for translational studies To characterize the patient population by determination of intra-tumoural expression of ErbB1 (EGFR) and ErbB2 (Her2/neu). |
|
E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
(For patients where sufficient tumour samples are available for translational study analysis, and if consented to): To characterise the patient population by determination of intra-tumoural expression of ErbB1 (EGFR) and ErbB2 (Her2/neu).
Objectives: - To characterise the intra-tumoural expression of drug resistance pumps in pancreatic cancer e.g. MRP-1 and PgP. - Exploratory proteomic profiling of patient serum samples pre- and post-treatment. - Where sufficient tumour material is available, to examine the mutational status of the K-ras gene. - Where sufficient tumour material is available, both the EGFR and Her2 receptor may be analysed by FISH (upon consultation with the Prinicpal Investigator).

E.3 | Principal inclusion criteria |
• Patients must have histologically or cytologically confirmed metastatic adenocarcinoma of the pancreas.
• Patients may have measurable or non measurable disease. - Measurable disease is defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as > or = 20 mm with conventional techniques or as > or = 10 mm with spiral CT scan.
• Patients may have received prior radiation therapy or surgery however toxicities must have resolved to NCI CTCAE < or = 1
• Age > or = 18 years. Because no dosing or adverse event data are currently available on the use of lapatinib in patients <18 years of age, children are excluded from this study.
• Life expectancy of greater than 12 weeks.
• ECOG performance status 0-1
• Adequate hematologic, renal and hepatic function measured within 14 days prior to commencing study treatment as defined below:
Body System and Adequate Function Definitions: SYSTEM LABORATORY VALUES Hematologic: ANC (absolute neutrophil count) > or = 1.5 x 10^9/L Haemoglobin > or = 9 g/dL Platelets > or = 100 x 10^9/L
Hepatic Albumin > or = 2.5 g/dL Serum bilirubin < or = 1.5 x ULN (< or = 2.5 x ULN if patient has Gilbert’s syndrome) AST and ALT < or = 3 x ULN without liver metastases (< or =5 x ULN if documented liver metastases)
Renal Serum Creatinine < 1.5 x ULN
• Cardiac ejection fraction within the institutional range of normal as measured by echocardiogram or MUGA scan. Note that baseline and on treatment scans should be performed using the same modality and preferably at the same institution.
• The effects of lapatinib on the developing human fetus at the recommended therapeutic dose are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control or abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.
• Ability to understand and the willingness to sign a written informed consent document.
• Able to swallow and retain oral medication
• Subjects must complete all screening assessments as outlined in the protocol
|
|
E.4 | Principal exclusion criteria |
• Patients may not have received chemotherapy for locally advanced or metastatic pancreatic cancer. Patients may have received prior chemotherapy in the adjuvant setting. This therapy may have included treatment with 5-fluorouracil as a radiation sensitiser only. Patients must have a minimum treatment free interval of 3 months.
• Patients who have had prior treatment with EGFR or ErbB2 targeting therapies.
• Patients who have had prior treatment with Capecitabine are not permitted to enter the study.
• Patients who have current active hepatic or biliary disease (with exception of patients with Gilbert's syndrome, asymptomatic gallstones, liver metastases or stable chronic liver disease per investigator assessment).
• Patients with a known dihyropyrimidine dehydrogenase (DPD) deficiency.
• Patients may not be receiving any other investigational agents or receiving concurrent anticancer therapy. In addition, all herbal (alternative) medicines are excluded.
• Patients with known brain metastases or leptomeningeal disease are excluded from this clinical trial
• History of other malignancy. Subjects who have been disease-free for 5 years or subjects with a history of completely resected non-melanoma skin cancer or successfully treated in situ carcinoma are eligible.
• Use of an investigational drug within 30 days or 5 half-lives, whichever is longer, preceding the first dose of study medication
• Known immediate or delayed hypersensitivity reaction or idiosyncrasy to drugs chemically related to lapatinib or excipients of lapatinib
• Known immediate or delayed hypersensitivity reaction or idiosyncrasy to drugs chemically related to capecitabine, fluorouracil or any excipients
• Uncontrolled inter-current illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
• Pregnant women are excluded from this study because lapatinib is member of the 4-anilinoquinazoline class of kinase inhibitors with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with lapatinib, breastfeeding should be discontinued if the mother is treated with lapatinib.
• HIV-positive patients receiving combination anti-retroviral therapy are excluded from the study because of possible pharmacokinetic interactions with lapatinib.
• Patients with GI tract disease resulting in an inability to take oral medication, malabsorption syndrome, a requirement for IV alimentation, prior surgical procedures affecting absorption, uncontrolled inflammatory GI disease (e.g., Crohn’s, ulcerative colitis).
• Patients with concomitant requirement for medication classified as CYP3A4 inducers or inhibitors
• Patients with active cardiac disease within the last six months, defined as: - Uncontrolled angina - Clinically significant arrhythmia, with the exception of asymptomatic atrial fibrillation requiring anticoagulation - Myocardial infarction < 6 months from study entry - Uncontrolled or symptomatic congestive heart failure - Ejection fraction below the institutional normal limit - Any other cardiac condition, which in the opinion of the treating physician, would make this protocol unreasonably hazardous for the patient

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome measure is the overall survival (OS), measured as the number of weeks or fraction of a week between a patient’s enrolment and his or her date of death. Patients who are still living six months after the last patient has been enrolled will be censored for the analyses, using the number of days between enrolment and the date of their last follow-up as their overall survival measurement. |

A subject has completed study when the subject has died, been lost to follow-up or other reasons prevent further data being collected on that subject. Study treatment is considered completed on withdrawal for: disease progression, unacceptable toxicity, other reasons (e.g., subject refuses further treatment, protocol violation, withdrawal of consent); subjects should continue to be followed for survival until death. |
