Pomalidomide - GI bleeding or Nose bleeding

Pomalidomide in HHT and Transfusion-Dependent Vascular Ectasia: a Phase I Study

Principal Investigator: Keith McCrae, MD


This study will be conducted at Cleveland Clinic Main Campus and Regional Hospital Facilities. This study will evaluate patients with GI bleeding due to HHT or with HHT-related nosebleeds that require ongoing transfusion or iron replacement therapy. Patients with GI bleeding must have a requirement for at least 4 units of blood or 1 gm of iron infusion per 4 month period, while patients with nosebleeds must require 2 units of blood or 500 mg of iron per 4 month period. The effect of Pomalidomide on bleeding will be assessed during an initial 4-5 month period in which the dose of Pomalidomide is increased monthly, as needed. Patients will then be observed over a 4 month period on a dose of Pomalidomide found to be effective, then over a dose tapering period and for 6 months after stopping the drug.

Study Question

Will Pomalidomide therapy reduce bleeding and the requirement for ongoing transfusion or iron therapy in patients with HHT by 50% or greater?

Study Goals

  1. To determine whether the use of Pomalidomide will reduce the requirement for transfusion and intravenous iron administration for patients with chronic gastrointestinal bleeding or nosebleeds due to HHT
  2. To monitor possible bleeding episodes in patients 6 months after discontinuation of Pomalidomide therapy.
