Pilot Study of Erlotinib for the Treatment of Patients With de Novo Acute Myeloid Leukemia

Phase 2

Completed

Brief Summary: This research study is looking for patients with newly diagnosed acute myeloid leukemia (AML), AML that has returned (relapsed), or it has not responded adequately to previous treatments. Treating certain patients with chemotherapy may not be to their benefit or may cause more harm than benefit. The purpose of this study is to find out what effects (good and bad) erlotinib has on patients and their AML.

Recruitment & Eligibility

Inclusion Criteria

Diagnosis of AML with no history of previous clonal/malignant hematologic disorders such as myelodysplastic syndromes or myeloproliferative disorders.
Newly diagnosed patients will be age 70 or older
Relapses patients will be age 60 or older any time following first relapse, if patient is not considered candidate/not interested in salvage chemotherapy.
Refractory disease patients will be age 18-59 who have failed at least 2 lines of conventional chemotherapy (1 induction and 1 salvage)
Patient must have discontinued all previous therapies for AML at least 14 days and recovered from the non-hematologic side effects of the therapy.
Laboratory tests must be within protocol-specified ranges
Patient must be able to swallow and tolerate oral medication.

Exclusion Criteria

Patients with known central nervous system (CNS) leukemia by spinal fluid cytology, flow cytometry or imaging.
History of antecedent pre-leukemic hematologic disorders such as myelodysplastic syndromes or myeloproliferative disorders.
Diagnosis of acute promyelocytic leukemia (APL)
Patients who require chronic anticoagulation, are current smokers or who are taking rifabutin, rifapentine, phenytoin, carbamazepine, phenobarbital and St. John's Wort are not eligible.
Patients with active corneal erosions or history of abnormal corneal sensitivity test.
Patients with serious illness such as: significant ongoing or active infection, New York Heart Association (NYHA) Grade II or greater congestive heart failure, unstable angina (anginal symptoms at rest), new onset angina (began within the last 3 months), myocardial infarction within the past 6 months, cardiac ventricular arrhythmias requiring anti-arrhythmic therapy, cerebrovascular accident within past 3 months, or psychiatric illness that would limit compliance with the study requirements.

Primary Outcome Measures

Name	Time	Method
Overall Response Rate (Defined as Partial Remission or Better) to 3 Months of Treatment With Erlotinib	3 months of treatment with erlotinib	The percent of patients were shown as having a partial remission or better based on definitions of response in AML. Partial remission includes a decrease of at least 50% in the percentage of blasts to 5% to 25% in the bone marrow aspirate. Complete remission includes presence of less than 5% blasts in an aspirate sample with marrow spicules and with a count of at least 200 nucleated cells. The percent and 95% exact confidence intervals will be calculated.

Secondary Outcome Measures

Name	Time	Method
Duration of Response (up to One Year Follow up) in Patients Who Achieve a Complete Remission	1 year after treatment discontinuation	The duration of response is from the time of response until failure or until the end of follow-up for the patients who received complete remission. Complete remission includes presence of less than 5% blasts in an aspirate sample with marrow spicules and with a count of at least 200 nucleated cells.
Treatment Related Adverse Events Grade 3 or Higher	up to 15 months	Adverse events will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 3.0. Grading scale will be from 1 (mild) to 5 (causing death). This will determine the number of unique patients who had a treatment related (possible, probable or definite) adverse event that was graded 3 or greater.
