Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Danazol
Treatment: Drugs - Placebo

Active comparator: Danazol - 800mg daily in two divided doses orally for 12 months. In subjects who have difficulty tolerating danazol / placebo, the dose will be reduced by 200mg/day and side effects will be reassessed. If symptoms related to the study drug persist, subsequent 200mg/day dose reductions will be allowed until a tolerated dose is achieved. Background antifibrotic therapy is allowed.

Placebo comparator: Placebo - Matching placebo capsules.


Treatment: Drugs: Danazol
Danazol up to 800mg daily in two-divided doses.

Treatment: Drugs: Placebo
Matching placebo.
