Imatinib Mesylate in Treating Patients With Recurrent Small Cell Lung Cancer

This study has been completed.

National Cancer Institute (NCI) Identifier:
First received: January 24, 2003
Last updated: October 7, 2013
Last verified: October 2013
Phase II trial to study the effectiveness of imatinib mesylate in treating patients who have recurrent small cell lung cancer. Imatinib mesylate may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth.

Condition Intervention Phase
Recurrent Small Cell Lung Cancer
Drug: imatinib mesylate
Other: laboratory biomarker analysis
Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Phase II Trial of STI571 in Patients With Relapsed Small Cell Lung Cancer

Primary Outcome Measures:
  • The proportion of patients progression-free [ Time Frame: 16 weeks ]
    Ninety-five percent confidence intervals for the true success proportion will be calculated according to the approach of Duffy and Santner.

Secondary Outcome Measures:
  • Survival time [ Time Frame: From registration to death due to any cause, assessed up to 3 years ]
    Estimated using the method of Kaplan-Meier.

  • Time to disease progression [ Time Frame: From randomization to documentation of disease progression, assessed up to 3 years ]
    Estimated using the method of Kaplan-Meier.

  • Duration of response (complete response [CR] or partial response [PR]) [ Time Frame: The date from which the patient's objective status if first noted to be either a CR or PR to the date progression is documented, assessed up to 3 years ]
  • Time to treatment failure [ Time Frame: From the date of registration to the date at which the patient is removed from treatment due to progression, toxicity, refusal, or death, assessed up to 3 years ]
  • Toxicity defined as adverse events that are classified as either possibly, probably, or definitely related to study treatment, per the National Cancer Institute (NCI) Common Toxicity Criteria (CTC) version 2.0 [ Time Frame: Up to 3 years ]
    The maximum grade for each type of toxicity will be recorded for each patient, and frequency tables will be reviewed to determine toxicity patterns.

Estimated Enrollment: 91
Study Start Date: May 2003
Primary Completion Date: October 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Treatment (imatinib mesylate)
Patients receive oral imatinib mesylate twice daily for 28 days. Courses continue in the absence of disease progression or unacceptable toxicity.
Drug: imatinib mesylate
Given orally
Other: laboratory biomarker analysis
Correlative studies

Detailed Description:


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

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

III. 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.
