Safety and Efficacy of Inhaled Interferon Gamma-1b in Pulmonary MAC Infection

This study has been terminated.
Information provided by:
InterMune Identifier:
First received: August 7, 2002
Last updated: October 30, 2007
Last verified: October 2007

The purpose of this research study is to test the safety and effectiveness of inhaled Interferon gamma-1b (IFN-g 1b), when administered for 48 weeks and in combination with oral antibiotics which may be administered for up to 72 weeks for the treatment of a lung infection caused by a bacterium called Mycobacterium avium complex .

FDA has not approved Interferon gamma-1b for use in patients with MAC infection of the lungs, which is the purpose of this study.Interferon gamma-1b and similar proteins play important roles in establishing and maintaining protective immune responses against a variety of microorganisms.

Condition Intervention Phase
Lung Infection Drug: interferon gamma-1b Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Randomized, Double-Blind, Placebo-Controlled, Phase II Study of Safety and Efficacy of Inhaled Interferon Gamma-1b With Antimycobacterials in Previously Treated or Mod-to-Sev Pulmonary Mycobacterium Avium Complex Infection

Primary Outcome Measures:
  • sustained culture conversion [ Time Frame: 52 weeks ]

Enrollment: 100
Study Start Date: December 2000
Study Completion Date: February 2003
Intervention Details:
    Drug: interferon gamma-1b
    500 mcg, oral, three times weekly
Detailed Description:
Laboratory research has shown that a mouse form of interferon gamma is effective in treating mice with infections caused by bacteria similar to MAC as well as MAC infection.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Male and female patients, 18 years of age or older, with bacteriologically and radiographically confirmed pulmonary MAC infection who have been treated for their infection for at least 6 months within the previous 2 years, as well as patients with moderate or severe pulmonary disease due to MAC, not previously treated for this infection. Patients with recurrent pulmonary MAC infection after previous successful treatment for pulmonary MAC disease are also eligible.

In addition, various laboratory testing must confirm conditions. Patients cannot be positive for HIV or have an extra-pulmonary (in general, outside of the lungs) infection of MAC. Other preconditions related to health or other conditions exist as factors for inclusion or exclusion from this study.
