Official title: Safety Profile of Iodopovidone as an Agent for Pleurodesis in Malignant Pleural Effusion

Status Completed

Clinical Trial Summary

Iodopovidone is safe when using as a pleurodesis sclerosing agent for malignant pleural effusion, with minimal adverse events, especially reducing dose.

Clinical Trial Description

Background: Chemical pleurodesis is the treatment of choice in most cases of malignant pleural effusion. The literature mentions a variety of chemicals which may be used for this purpose, each with its own advantages and disadvantages. The iodopovidone has been recently studied due to the existence of some side effects of other agents. Nevertheless, there are still some questions in the literature regarding its safety and possible adverse effects. Because of these questions, we propose the development of a study to ensure the safety and efficacy of iodopovidone as a pleurodesis sclerosing agent.

Objective: The main purpose of this study is to evaluate the safety of pleurodesis for malignant pleural effusion using iodopovidone as a sclerosing agent in different doses. The secondary objectives are to determine clinical efficacy and quality of life of the patients after realization of the proposed procedure.

Methods: There will be a randomized clinical trial, covering patients diagnosed with malignant pleural effusion at Hospital Aristides Maltez - Bahia League Against Cancer. The research was revised and approved by the Ethics in Research of the Heart Institute, Hospital das Clínicas - FMUSP and of the Hospital Aristides Maltez - Bahia League Against Cancer. The free and informed consent was evaluated by the same authority pursuant and the study group included only those who agree to participate and signed an approved. There included patients with malignant pleural effusion diagnosis. Main exclusion criteria were iodine allergia, renal failure, thyroid disease, refusal to sign the informed consent and patients unable to respond the quality of life questionnaire. After inclusion, patients were randomized and assigned to two groups according to the iodopovidone concentration solution: 1% or 2%. All procedures were performed by infusion of the solution through a chest tube previously placed.The data analysis involved clinical measures and complementary exams trying to evaluate all organ systems and sorting through possible adverse effects, classifying those as CTCAEV. Clinical measures involved MRC dyspnea schedule, analogic visual pain schedule, visual acuity test, measurement of pulse oximetry, heart rate, blood pressure and temperature. Complementary exams were chest x-ray, electrocardiogram and laboratory tests. Such measures were performed in the preoperative, immediate postoperative, second, fourth, eleventh and thirty days postoperative. Quality of life questionnaires was applied before and on thirty days postoperative as well. After that, randomized groups were compared. ;
