About this study
Giant cell arteritis , also named Horton's disease, is the most common vasculitis in subjects over 50 years old. The incidence increases with age : from 188 to 290 cases per million inhabitants per year, with a North-South gradient.
The major risk of Horton's disease is blindness, unilateral, occurring in 15 to 20% of cases, sometimes preceded by episodes of transient amaurosis. The decrease in visual acuity is often brutal, irreversible and bilateral in 25 to 50% of cases. The mechanism of this blindness is an arterial ischemia: Acute Anterior Ischemic Optic Neuropathy acute anterior ischaemic optic neuropathy (90%), acute retro-bulbar ischaemic optic neuropathy (5%), occlusion of the central artery of the retina (5%).

The pathogenesis of this brutal ischemia is not fully understood. One of the hypotheses suggests that, during stimulation by an antigen of the environment, preactivated dendritic cells of the arterial wall would stimulate T lymphocytes. These will recruit cells that cause an inflammatory infiltrate polymorphic predominant at the media level. These lesions may be accompanied by destruction of the internal elastic lamina, with inconstant but pathognomonic presence of multinucleated giant cells. All arteries with internal elastic lamina can be affected by parietal inflammation, which results in stenosis and occlusion, explaining the ischemia.
The visual loss is usually abrupt and very severe, leaving the patient with definitely very low or no residual visual acuity.
Conventional treatment currently recommended includes systemic corticosteroid therapy at 1 mg / kg / day, preceded or not by 500 mg pulses of methylprednisolone , and associated with antiplatelet and anticoagulant therapy (LMWH). Despite the decline in visual acuity thus occurred is then always final. Certainly loss of vision has a major impact on the quality of life of patients.
Apart from this lymphocytic inflammation, a process of vascular remodeling is at the origin of the vascular occlusion phenomenon. The endothelin system is a family of amino acids including 3 members: ET1, ET2 and ET3. ET1 is a potent vasoconstrictor. ET1 receptors (ETA and ETB) are expressed in the arteries of patients with giant cell arteritis . The expression of ET1 associated with proliferation of muscle cells in arteries will decrease under the effect of endothelin inhibitors. This has been shown during treatment of pulmonary hypertension. In giant cell arteritis , the endothelin system continues to be very active up to 8 days despite the introduction of systemic corticosteroids. Bosentan is a mixed endothelin receptor antagonist with affinity for both ETA and ETB receptors. This inhibitor is used in treatment of pulmonary artery hypertension, digital ulcerations of systemic sclerosis and critical peripheral arterial ischemia.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Giant cell arteritis , also named Horton's disease, is the most common vasculitis in subjects over 50 years old. The incidence increases with age : from 188 to 290 cases per million inhabitants per year, with a North-South gradient.
The major risk of Horton's disease is blindness, unilateral, occurring in 15 to 20% of cases, sometimes preceded by episodes of transient amaurosis. The decrease in visual acuity is often brutal, irreversible and bilateral in 25 to 50% of cases. The mechanism of this blindness is an arterial ischemia: Acute Anterior Ischemic Optic Neuropathy acute anterior ischaemic optic neuropathy (90%), acute retro-bulbar ischaemic optic neuropathy (5%), occlusion of the central artery of the retina (5%).

One of the hypotheses suggests that, during stimulation by an antigen of the environment, preactivated dendritic cells of the arterial wall would stimulate T lymphocytes. These will recruit cells that cause an inflammatory infiltrate polymorphic predominant at the media level. These lesions may be accompanied by destruction of the internal elastic lamina, with inconstant but pathognomonic presence of multinucleated giant cells. All arteries with internal elastic lamina can be affected by parietal inflammation, which results in stenosis and occlusion, explaining the ischemia.
The visual loss is usually abrupt and very severe, leaving the patient with definitely very low or no residual visual acuity.
Conventional treatment currently recommended includes systemic corticosteroid therapy at 1 mg / kg / day, preceded or not by 500 mg pulses of methylprednisolone , and associated with antiplatelet and anticoagulant therapy (LMWH).

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing treatment in people with Arteritis, Giant Cell and Blindness and Low Vision, run by Centre Hospitalier Universitaire de Nice at 1 site in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 18 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Visual acuity calculated according to the Early Treatment Diabetic Retinopathy Study (time frame: 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03841734, which also lists 15 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
