Can a cancer drug calm the nosebleeds of a rare bleeding disorder?
NCT ID NCT07828015
First seen Sep 18, 2026 · Last updated Sep 18, 2026
Summary
Hereditary hemorrhagic telangiectasia (HHT) causes tangled blood vessels that lead to frequent, hard-to-stop nosebleeds and low hemoglobin. Researchers are testing whether intravenous bevacizumab, given once or twice a year after nasal electrocoagulation, reduces nosebleed severity and raises hemoglobin in 40 people with moderate-to-severe HHT. The study also tracks genetic and clinical factors that may explain why some patients respond better than others.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- bevacizumab, an intravenous drug that blocks a blood-vessel growth signal
- What this could lead to
- If it works, bevacizumab could become a repeat infusion option that cuts severe nosebleeds and raises hemoglobin for people with HHT. Doctors might also learn which patients respond best.
- What could go wrong
- This is a small Phase 2 study of 40 people, so results may not hold in larger groups. Bevacizumab carries risks of bleeding, high blood pressure, and blood clots, and some patients may not respond.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Definite HHT diagnosis is established by either clinical assessment according to the Curaçao criteria or genetic confirmation. Clinical diagnosis (Curaçao criteria) Patients who meet at least 3 of the following 4 items are diagnosed with definite HHT: Spontaneous, recurrent epistaxis Multiple mucocutaneous telangiectasias at typical sites Visceral arteriovenous malformations (lung, liver, brain, gastrointestinal tract, etc.) Positive family history of HHT in a first-degree relative Genetic diagnosis Identification of a pathogenic germline mutation in HHT-associated genes (ENG, ACVRL1) confirms the diagnosis of HHT. Exclusion Criteria: * Minors, patients with mild epistaxis that can be well controlled by other treatments, and patients with any contraindication to bevacizumab treatment.
