INS316 in Diagnosing Lung Cancer in Patients With Untreated Lung Cancer
RATIONALE: Doctors can diagnose lung cancer by collecting mucus coughed up from the lungs and examining it under a microscope to look for cancer cells. Breathing in INS316 may make it easier for patients to cough up mucus.
PURPOSE: Randomized phase II trial to study the effectiveness of INS316 in helping to diagnose lung cancer.
|Study Design:||Primary Purpose: Diagnostic|
|Official Title:||Evaluation Of Uridine 5-Triphosphate Solution For Inhalation (UTP) As An Adjunct In The Diagnosis Of Lung Cancer By Sputum Cytology|
|Study Start Date:||August 2000|
|Study Completion Date:||May 2004|
OBJECTIVES: I. Determine whether a cytological diagnosis of lung cancer can be obtained more frequently from sputum specimens following inhalation of INS316 compared to specimens obtained following placebo or compared to specimens spontaneously expectorated in patients with untreated lung cancer. II. Assess the relative sensitivity of sputum cytology in the diagnosis of lung malignancies in this patient population using these sputum collection regimens. III. Determine the quantity of macrophages in sputum of these patients using these techniques. IV. Determine if the number of macrophages in sputum obtained by these methods is predictive of the likelihood of obtaining a positive diagnosis of lung cancer in these patients. V. Determine the total amount of sputum expectorated from these patients using these techniques.
OUTLINE: This is a randomized, double-blind, placebo-controlled, cross-over, multicenter study. Patients are randomized to one of two arms, then cross-over to the other arm. Arm I: Patients receive INS316 by inhalation via a nebulizer. Sputum is collected throughout the dosing and for 1 hour post dosing. Arm II: Patients receive placebo in the same manner as INS136 in arm I. All patients receive both treatments. Patients receive the first dose no more than 7 days after screening, and the second dose 3 to 10 days after the first dose. Patients are followed 1 day after completion of the second treatment. The sputum samples are fixed and examined cytologically.
PROJECTED ACCRUAL: Approximately 100-130 patients will be accrued for this study.
