About

This phase I trial studies the side effects and best dose of gemcitabine hydrochloride and dasatinib when given together with erlotinib hydrochloride in treating patients with pancreatic cancer that has spread to other places in the body or cannot be removed by surgery. Drugs used in chemotherapy, such as gemcitabine hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Dasatinib and erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving gemcitabine hydrochloride and dasatinib together with erlotinib hydrochloride may kill more tumor cells.

Full description

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose (also phase II recommended dose) of the combination of gemcitabine (gemcitabine hydrochloride), erlotinib (erlotinib hydrochloride) and dasatinib in patients with advanced pancreatic adenocarcinoma.

SECONDARY OBJECTIVES:

I. To determine the safety profile of the combination of gemcitabine, erlotinib and dasatinib.

II. To evaluate the response rate and response duration of advanced pancreatic adenocarcinoma treated with dasatinib, erlotinib and gemcitabine.

III. To determine progression-free survival and overall survival for this group of patients.

IV. To determine the utility of advanced magnetic resonance imaging techniques to assess in vivo effects of therapy (changes in tumor vascularity, cellularity).

V. To assess the use of serum markers as predictors of response and outcome.

OUTLINE: This is a dose-escalation study of gemcitabine hydrochloride and dasatinib.

Patients receive gemcitabine hydrochloride intravenously (IV) over 30-60 minutes on days 1, 8, and 15, and dasatinib orally (PO) once daily (QD) and erlotinib hydrochloride PO QD on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up for 30 days and then every 4 weeks thereafter.

Enrollment: 19 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

• Aspartate aminotransferase (AST) (serum glutamic pyruvate transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x institutional upper limit of normal OR =< 5 x institutional upper limit of normal when liver metastases are present
• Creatinine within normal institutional limits OR creatinine clearance >= 60 mL/min/1.73 m^2 for patients with creatinine levels above institutional normal
• Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; 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

• Patients must be able to swallow pills

Exclusion criteria

• Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier (with the exception of alopecia and neuropathy); no radiation is allowed on study

• Patients who are receiving any other investigational agents

• Major surgical procedure within 4 weeks of treatment

• Patients with known brain metastases

• History of allergic reactions attributed to compounds of similar chemical or biologic composition to dasatinib, erlotinib or gemcitabine

• Uncontrolled intercurrent 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, breastfeeding should be discontinued if the mother is treated with erlotinib or dasatinib

• Patients with immune deficiency are excluded

• Patients on potent cytochrome P450, family 3, subfamily A, polypeptide 4 (CYP3A4) inducers and inhibitors

• Malabsorption syndrome or other condition that would interfere with intestinal absorption

• Other active malignancy (with the exception of locally treated non-melanoma skin cancers)

• Human immunodeficiency virus (HIV) positive patients who are on combination antiretroviral therapy

  • Myocardial infarction or ventricular tachyarrhythmia within 6 months
  • Prolonged corrected QT (QTc) > 480 msec (Fridericia correction)
  • Known ejection faction less than institutional normal
  • Major conduction abnormality (unless a cardiac pacemaker is present)
