NOSTRIL Trial 

A Randomized Trial of Doxycycline for HHT-Related Epistaxis (Nose Bleeding)

Study Summary

Doxycycline, an inexpensive generic medication used by physicians for decades to treat bacterial infections, has displayed potent properties in blocking growth of new blood vessels inside and outside the body. The purpose of this study is to determine whether Doxycycline can be used to control nosebleeds (epistaxis) for patients with HHT.

Patients who are enrolled into the NOSTRIL Trial will be randomized to start with either the study medication (doxycycline) or a placebo. Subjects will take one treatment for 2 months followed by a 1-month washout period and then switch to the other treatment for another 2 months and a 1-month follow-up visit, which will mark the end their 6 month participation in the NOSTRIL Trial.

Your participation in this study is expected to last 6 months, with up to 6 clinic visits at UCLA for labs, questionnaires, and a physical exam.
