Is this trial a fit for you?

Likely a good fit

Adults (≥18 years) with a confirmed supratentorial spontaneous intracerebral hemorrhage who can start the study drug within 48 hours, can provide consent, and have French social insurance are ideal candidates.

Probably not a fit

Patients with massive hematomas (>60 ml), severe coma (GCS <6), pure intraventricular hemorrhage, ICH from trauma or other secondary causes, or those requiring immediate surgical evacuation are unlikely to benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a randomized, double-blind, placebo-controlled phase 2 multicenter trial of diroximel fumarate (DRF) versus placebo in adults with supratentorial spontaneous intracerebral hemorrhage. Study treatment is given no later than 48 hours after symptom onset and patients are followed with brain imaging to measure peri‑hematomal edema growth and with clinical scales for functional outcome. Key exclusions include very large hematomas, severe coma, pure intraventricular hemorrhage, secondary causes such as trauma or vascular malformation, and planned surgical evacuation. The intervention aims to modulate inflammation via Nrf2 activation to limit edema and promote blood resorption.

Why it matters

Potential benefit: If successful, the drug could limit peri‑hematomal swelling and improve recovery and long‑term function after intracerebral hemorrhage.

How similar studies have gone: Preclinical animal studies and human post‑mortem data support Nrf2 activation as protective, but clinical testing of Nrf2‑targeting agents in ICH is novel and has not yet demonstrated established clinical success.
