Ethambutol Clinical Trials

TBTC Study 24: Intermittent Treatment of TB With Isoniazid Resistance or Intolerance
This study is a prospective, open-label, nonrandomized trial using a largely-intermittent, six-month tuberculosis treatment regimen among patients who will not receive isoniazid due to the presence of initial isoniazid resistance or intolerance. Subjects are enrolled after resistance or [more...] intolerance to isoniazid has been documented, and are treated for a total of six months (nine months if baseline chest x-ray shows cavitation and 2-month sputum culture is positive) with twice weekly or thrice weekly rifampin, ethambutol, and pyrazinamide.
Status: Active, not recruiting Start Date: August 2000 Completion Date: July 2007

Phase II Study of Amithiozone (Thiacetazone) for Patients With Mycobacterium Avium Complex Pulmonary Disease
OBJECTIVES: I. Determine the bacteriological activity of amithiozone against Mycobacterium avium complex (MAC) pulmonary disease. II. Define the ability of amithiozone to improve clinical outcomes in patients with MAC infection. III. [more...] Determine the safety and tolerance of amithiozone with chronic dosing in these patients. IV. Assess the contribution of clarithromycin, streptomycin, rifampin, ethambutol, kanamycin, and amithiozone in the treatment of pulmonary MAC infection.

Tuberculosis Treatment Shortening Trial
Tuberculosis (TB) is a serious infection that can affect the lungs and other parts of the body. The usual way to treat TB is to take 4 medicines by mouth every day for 2 months, then take 2 of the same medicines for 4 [more...] more months, for a total of 6 months. The purpose of this study is to see if taking 4 months of TB medicines is as effective in curing some TB patients as taking 6 months of TB medicines. Study participants will include 758 human immunodeficiency virus (HIV)-non-infected individuals, ages 18-60. Participants will be treated with 4 standard drugs called isoniazid, rifampicin, pyrazinamide and ethambutol. All individuals will take TB medicines for at least 4 months. After 4 months of treatment, if no TB germs are growing in sputum samples, participants will be assigned to either stop taking TB medicine (4 months of treatment) or to continue taking TB drugs for 2 more months (6 months of treatment). Participants will be involved in study procedures for up to 30 months.
Status: Completed Start Date: April 2002 Completion Date: November 2008

Effect of Weight and/or Obesity on Ethambutol Drug Concentrations
This study is designed to measure drug concentrations in the blood of healthy volunteers administered a single dose of ethambutol. Our hypothesis is that volunteers with a body mass index (BMI) 25-40 kg/m2 will remove ethambutol more quickly from the blood than leaner [more...] volunteers, and those with a BMI > 40 kg/m2 will have even greater clearance than those who are leaner.
Status: Completed Start Date: January 2010 Completion Date: December 2010

Clinical trials allow volunteers access to medical treatment options before they are available to the general public. Participants often receive the best healthcare available for their condition.

Risks are a reality, however, and may include more frequent doctor visits, health risks (possibly life-threatening), and/or the treatment being ineffective. Trials are federally regulated with strict guidelines to protect participants.

Ethambutol Clinical Trials Information presented on ClinicalTrialsSearch.org is not intended to be a substitute for qualified medical advice visit or treatment with a real physician. We are not physicians. Always consult with a medical doctor (MD). ClinicalTrialsSearch.org is a website dedicated to listing clinical research studies in human subjects, including those specifically related to Ethambutol. Clinical research trials and medical trials take place in hundreds of cities across the United States. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials generally measure the effectiveness of new treatments and drugs. The purpose of the studies is to answer specific human health questions. Clinical trials are a popular way for doctors, government agencies, and private sector companies to find treatments for all kinds of conditions. Clinical trials allow volunteers access to medical treatment options before they are available to the general public. Many times the participants receive treatment for free, and sometimes they are paid for their time. Participants often receive the best healthcare available possible for their condition. Risks are a reality, however, and may include more frequent doctor visits, health risks (possibly life-threatening), and/or the treatment being ineffective. U.S. - based Ethambutol studies are federally regulated with strict guidelines to protect patients.
