Erlotinib and Everolimus in Treating Patients With Metastatic Breast Cancer

• Status: Completed
• Trial end date: 2009-02-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Erlotinib and everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving erlotinib together with everolimus may kill more tumor cells.

PURPOSE: This phase I/II trial is studying the side effects and best dose of giving erlotinib together with everolimus and to see how well it works in treating patients with metastatic breast cancer.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Vanderbilt-Ingram Cancer Center
• Collaborator: National Cancer Institute (NCI)
• Treatments: Erlotinib Hydrochloride; Everolimus; Protein Kinase Inhibitors; Sirolimus

Criteria

DISEASE CHARACTERISTICS:

• Histologically confirmed adenocarcinoma of the breast

• Evaluable metastatic disease (no need for measurable disease)

• Must have had anthracycline therapy in the adjuvant setting or failed anthracycline treatment in the metastatic setting

• Total cumulative dose of lifetime exposure of doxorubicin not greater than 360 mg/m^2 or epirubicin not greater than 640 mg/m^2

• Taxane use in the adjuvant setting with metastatic relapse within 12 months of therapy

• Progression on taxane therapy in the metastatic setting

• Discontinuation of taxane therapy in the metastatic setting secondary to lack of resolution of ≥ grade 2 toxicity

• No symptomatic brain metastases

• Patients with a history of brain metastases are eligible provided they are clinically stable and not taking steroids or therapeutic anticonvulsants that are CYP3A4 modifiers

• Patients with asymptomatic brain metastasis are eligible provided they are not on prophylactic anticonvulsants that are CYP3A4 modifiers

• Hormone receptor status not specified

PATIENT CHARACTERISTICS:

Inclusion criteria

• Menopausal status not specified

• ECOG performance status 0-1

• SGOT and SGPT ≤ 2.5 times ULN

• Albumin > 30 g/L

• Creatinine ≤ 1.5 upper limit of normal

• INR normal provided the patient is not on warfarin therapy

• Not pregnant or nursing

• Negative pregnancy test for premenopausal patients

• Fertile patients must use effective barrier method contraception during and for 3 months after completion of study treatment

• Impairment of lung function (COPD, lung conditions requiring oxygen therapy)

• Symptomatic congestive heart failure (New York Heart Association class III or IV heart disease)

• Unstable angina pectoris or myocardial infarction within the past 6 months

• Uncontrolled hypertension (i.e., systolic blood pressure > 180 mm Hg or diastolic blood pressure > 100 mm Hg, found on two consecutive measurements separated by a 1-week period despite adequate medical support)

• Clinically significant cardiac arrhythmia (multifocal premature ventricular contractions, bigeminy, trigeminy, ventricular tachycardia that is symptomatic or requires treatment)

• Uncontrolled diabetes

• Psychiatric illness/social situations that would compromise patient safety or limit compliance with study requirements including maintenance of a compliance/pill diary

PRIOR CONCURRENT THERAPY:

Inclusion criteria

• See Disease Characteristics

• Prior trastuzumab (Herceptin®) in the first-line treatment of metastatic breast cancer is required for patients who have HER2/neu overexpressing tumors

• More than 6 months since prior cardiac angioplasty or stenting

• Use of endocrine therapy (i.e., aromatase inhibitors, fulvestrant, tamoxifen or ovarian ablation) in the first-line treatment of metastatic breast cancer is required for patients who have estrogen receptor and or progesterone receptor expressing tumors

• Concurrent endocrine therapy is not allowed

• Patients may receive concurrent radiotherapy to painful bone metastases or areas of impending bone fracture as long as radiotherapy is initiated prior to study entry

• Patients who have received prior radiotherapy must have recovered from toxicity induced by this treatment

• More than 3 weeks since prior chemotherapy, biological or hormonal therapy while on protocol therapy.

• No other concurrent antineoplastic or antitumor agents, including chemotherapy, radiotherapy, immunotherapy, or hormonal anticancer therapy

Exclusion criteria

• More than 3 prior chemotherapy treatments in the metastatic setting

• This restriction does not include endocrine therapies or single agent biologic therapies (i.e., trastuzumab [Herceptin®])

• Use of steroids or immunosuppressants

• Use of CYP3A4 modifiers

• Concurrent therapy with trastuzumab (Herceptin®)

• Use of growth support factors (e.g., filgrastim [G-CSF], sargramostim [GM-CSF], recombinant erythropoietin) during the phase I portion of the study

• Other concurrent investigational agents
