Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 30 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2009-04-30
• Study Completion Date: 2013-12-31

Brief Summary

RATIONALE: Drugs used in chemotherapy, such as gemcitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Erlotinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving gemcitabine together with erlotinib may kill more tumor cells.

PURPOSE: This phase II trial is studying how well giving gemcitabine together with erlotinib works in treating patients with metastatic or recurrent pancreatic cancer.

Detailed Description

OUTLINE: This is a multicenter study.

Patients receive gemcitabine hydrochloride IV on days 1, 8, and 15 and oral erlotinib hydrochloride on days 2-5, 9-12, and 16-26. Treatment repeats every 28 days for up to 1 year in the absence of disease progression or unacceptable toxicity.

Archived tumor tissue samples are analyzed for the expression of EGFR, HER3, HER2, downstream signaling molecules, and other molecular markers by immunohistochemistry and RT-PCR. The presence of aberrant gene copy numbers (amplification and polysomy) for EGFR, HER3, and HER2 are determined by FISH. Blood samples are collected at baseline and periodically during study for polymorphism analysis and correlative molecular analysis of surrogate endpoint biomarkers.

After completion of study therapy, patients are followed every 3 months.

Study Groups

Gemcitabine and Erlotinib

The dose for gemcitabine is 1,000 mg/m2 administered over 30 minutes as an intravenous infusion. The doses are administered weekly for 3 weeks (Days 1, 8 and 15) followed by one week of rest during which gemcitabine is not given. This 4 week period (28 days) constitutes a cycle.Erlotinib will be dosed at 150mg orally (tablets) on days 2-5, 9-12, and 16-26 of a 28 day cycle.

Group Type: EXPERIMENTAL

Erlotinib

Intervention Type: DRUG

Erlotinib will be administered at 150 mg once daily by mouth on the following schedule: days 2-5, 9-12,16-26.

gemcitabine

Intervention Type: DRUG

Eligibility Criteria

Inclusion Criteria

• Histologically or cytologically confirmed locally advanced, metastatic or recurrent pancreatic carcinoma
• Must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension
• No prior chemotherapy for metastatic or recurrent disease is allowed. Prior adjuvant chemotherapy is allowed provided that patients did not receive gemcitabine and the chemotherapy was completed > six months prior to initiation of study therapy. Prior erlotinib therapy is not allowed
• Available tumor specimen that was obtained at the time of diagnosis and/or prior to study entry is highly encouraged
• Age ≥ 18 years
• Life expectancy greater than 3 months
• Zubrod performance status ≤ 2
• Patients must have normal organ and marrow function as defined below:
• leukocytes ≥ 3,000/μL
• absolute neutrophil count ≥ 1,500/ μL
• platelets ≥ 100,000/ μL
• total bilirubin ≤ 1.5 X institutional upper limit of normal
• AST(SGOT)/ALT(SGPT) ≤ 3 X institutional upper limit of normal, unless the liver is involved with tumor, in which case the AST/ALT must be ≤ 5 X institutional upper limit of normal
• creatinine clearance ≥ 50 mL/min/1.73 m2, as measured by 24hour collection OR
• creatinine ≤ 1.5 X institutional upper limit of normal
• The effects of erlotinib and gemcitabine on the developing human fetus at the recommended therapeutic doses are unknown. Women of child-bearing potential and men must agree to use adequate contraception prior to study entry and for the duration of study participation
• Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria

• Patients may not be receiving any other investigational agents.
• Patients with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to erlotinib or gemcitabine.
• Secondary primary malignancy. Concurrent or history of another malignancy < 5 years.
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, uncontrolled hypertension, or psychiatric illness/social situations that would limit compliance with study requirements.
• Pregnant women are excluded from this study because erlotinib and gemcitabine have the potential for teratogenic or abortifacient effects. Breastfeeding should be discontinued if the mother is treated with study drugs.
• Patients with immune deficiency are at increased risk of lethal infections when treated with marrow-suppressive therapy.

• Minimum Eligible Age: 18 Years
• Eligible Sex: ALL
• Accepts Healthy Volunteers: No
