Resumen
Fecha de inicio: 31 de enero de 1997
Fecha en la que se inscribió al primer participante.OBJECTIVES: I. Determine whether treatment with the oral matrix metalloproteinase inhibitor (MMPI) marimastat prolongs overall survival and time to progression in patients with small cell lung cancer who have achieved complete or partial remission after first line chemotherapy, with or without radiotherapy. II. Determine the tolerability and toxicity of prolonged administration of marimastat in patients with small cell lung cancer. III. Determine the effect of prolonged administration of marimastat on the quality of life of patients with small cell lung cancer. OUTLINE: This is a randomized, double blind, multicenter, placebo controlled study. Patients are stratified by stage of disease at diagnosis, response to prior chemotherapy/radiotherapy, type of thoracic radiotherapy, and cooperative group. Patients are randomized into two groups. Half of the patients take marimastat orally twice a day (breakfast and evening meal); the other half take placebo orally twice a day (breakfast and evening meal). Treatment continues for 2 years or until documented disease recurrence or progression and institution of further anticancer treatment, occurrence of unacceptable toxicity, initiation of anticoagulant treatment, or development of intercurrent illness. All patients are followed every 6 months until death. PROJECTED ACCRUAL: The planned sample size is 360, with an equal number of patients in both arms, accrued at a rate of 240 responders per year (resulting in an accrual period of approximately 1.5 years). The total duration of the study is estimated as 2.3 years.
