Enrolling: HHT Clinical Study

Living with hereditary hemorrhagic telangiectasia (HHT) can mean coping with frequent nosebleeds, fatigue, anemia, and the uncertainty these symptoms can bring to everyday life. At Vaderis, we believe people living with HHT deserve more treatment options, and we are committed to advancing research that may help improve life for this community.

The HEROIC Phase 3 clinical study is evaluating engasertib, an investigational oral therapy, in adults with moderate to severe HHT.

The study is designed to better understand whether engasertib can help reduce the frequency of nosebleeds, improve daily life for people living with HHT, and continue to assess its safety over a longer treatment period.

Conducted at clinical sites around the world, HEROIC represents an important step toward advancing research for HHT. We invite you to learn more about the study, what participation involves, and whether it may be right for you.

  • Daily dosing with oral study medication
  • Study Visits
  • In-person or virtual clinic visit approximately every 4 weeks
  • The total duration of the trial will be approximately 40 weeks, including the training period and any follow up after
