Imatinib Mesylate in Treating Patients With Recurrent Small Cell Lung Cancer

2014-08-27 03:55:33 | BioPortfolio

Summary

RATIONALE: Imatinib mesylate may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth.

PURPOSE: Phase II trial to study the effectiveness of imatinib mesylate in treating patients who have recurrent small cell lung cancer.

Description

OBJECTIVES:

- Determine the response rate, time to progression, and overall survival of patients with recurrent small cell lung cancer treated with imatinib mesylate.

- Correlate the presence of c-Kit mutations in tumor tissue with treatment response in patients treated with this drug.

- Correlate individual patient variation in clinical (toxicity and/or activity), pharmacologic (pharmacokinetic/pharmacodynamic parameters), and/or biologic (correlative laboratory study results) responses to this drug with genetic differences in proteins involved in drug response (transport, metabolism, and/or mechanism of action).

OUTLINE: This is a multicenter study. Patients are stratified according to length of prior therapy (less than 3 months vs at least 3 months).

Patients receive oral imatinib mesylate twice daily for 28 days. Courses continue in the absence of disease progression or unacceptable toxicity.*

Patients are followed every 3 months until disease progression and then every 6 months for up to 3 years after registration.

NOTE: *Patients who develop CNS metastasis as the only site of disease progression receive therapeutic whole-brain radiotherapy and then resume study therapy.

PROJECTED ACCRUAL: A total of 41 patients for stratum I will be accrued within 21 months and 50 patients for stratum II will be accrued within 25 months for this study.

A tyrosine kinase inhibitor and ANTINEOPLASTIC AGENT that inhibits the BCR-ABL kinase created by chromosome rearrangements in CHRONIC MYELOID LEUKEMIA and ACUTE LYMPHOBLASTIC LEUKEMIA, as well as PDG-derived tyrosine kinases that are overexpressed in gastrointestinal stromal tumors.

Tumors or cancer of the LUNG.

Malignant neoplasm arising from the epithelium of the BRONCHI. It represents a large group of epithelial lung malignancies which can be divided into two clinical groups: SMALL CELL LUNG CANCER and NON-SMALL-CELL LUNG CARCINOMA.

Nuclear phosphoprotein encoded by the p53 gene (GENES, P53) whose normal function is to control CELL PROLIFERATION and APOPTOSIS. A mutant or absent p53 protein has been found in LEUKEMIA; OSTEOSARCOMA; LUNG CANCER; and COLORECTAL CANCER.

A heterogeneous aggregate of at least three distinct histological types of lung cancer, including SQUAMOUS CELL CARCINOMA; ADENOCARCINOMA; and LARGE CELL CARCINOMA. They are dealt with collectively because of their shared treatment strategy.
