Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - Danicopan

Experimental: Danicopan - Starting doses of danicopan ranged from 100 to 150 milligrams (mg) three times daily (TID), with subsequent dose escalation up to 200 mg TID based on response (clinical and biochemical) for 28 days (Part 1). Participants with reductions in lactate dehydrogenase (LDH) meeting specified criteria were offered continued dosing beyond Day 28, for up to 8 additional weeks (Part 2).


Treatment: Drugs: Danicopan
Danicopan was administered as multiple oral doses over a period of at least 28 days.
