Summary
The purpose of this research study is to determine whether Doxycycline can be used to control nosebleeds (epistaxis) for patients with Hereditary Hemorrhagic Telangiectasia (HHT). Patients with HHT will be randomized to one of 2 study arms: Doxycycline or Placebo for a period of 2 months followed by a 1-month washout period before switching treatments for a further 2 months period. Observation and evaluation will continue for a period of one month after treatment is completed.
Eligibility Criteria
Inclusion Criteria
- Diagnosis of definite HHT by the Curacao criteria or genetic diagnosis of HHT
- Epistaxis severity during observation month at least moderate by Epistaxis Severity Score (ESS) evaluation
- For female participants, a negative pregnancy test at Day -1 and agree to use birth control during treatment and for 28 days following cessation of Doxycycline
Exclusion Criteria
- Use of medication(s) contraindicated with doxycycline use within 14 days prior to the study (including barbiturates, tegretol, dilantin, warfarin, isotretinoin)
