Dear all,

We are pleased to invite you to the upcoming event “Stroke: from the acute phase to life after”, which will take place on Tuesday, March 31, from 5:00 pm to 8:00 pm, at MAME – 49 boulevard Preuilly, Tours.

Organized by the Tours-based teams involved in stroke research, this new event will focus on the complexity of the recovery journey after a stroke. The evening will open with a public lecture dedicated to stroke (including intracerebral hemorrhage), its prevention, and its management.

This will be followed by a roundtable discussion bringing together patients, a sociologist, and physicians to explore the challenges of resuming personal and professional life, before a time for discussion with the audience.

Throughout the evening, an exhibition of photographs, paintings, and sculptures created by patients will offer a sensitive insight into the role of artistic activities in the recovery process.

This event follows the public awareness evening held on November 7, 2024, which brought together more than 100 participants. We would be honored to have you join us for this event and contribute to the discussions.

We kindly ask you to confirm your attendance HERE or through the QR code on the invitation.

Intracerebral haemorrhage remains one of the most severe forms of stroke, with a major impact on mortality and long‑term disability. While the first hours are crucial to limiting haematoma expansion, much of the patient’s prognosis is determined in the days that follow.
It is within this often‑overlooked window that DARLENE takes place, developed as part of Work Package 3 of the RHU TIPITCH, and dedicated to a central challenge: modulating post‑haemorrhagic inflammation.

Perihaemorrhagic Oedema: A Key Determinant of Outcome

When an intracerebral haemorrhage occurs, the bleeding itself represents only the first stage of the cerebral injury. The sudden entry of blood into brain tissue destroys cells at the point of impact and triggers an intense inflammatory reaction.

This inflammatory response leads to the formation of perihaemorrhagic oedema, which progressively develops over the following days. This oedema exerts mass effect on the surrounding brain and worsens the initial injury. Its severity is closely linked to functional outcome:
the larger the oedema, the higher the risk of severe disability or death.

Physiologically, this inflammation results from the activation of resident brain immune cells — microglia — as well as the recruitment of inflammatory cells from the bloodstream. It is accompanied by breakdown of the blood–brain barrier, promoting accumulation of fluid and inflammatory cells in brain tissue.

An Ambivalent Process That Cannot Simply Be “Blocked”

While excessive inflammation is clearly harmful, it is not solely detrimental. It also plays an essential role in haematoma clearance and tissue repair.

This is the core complexity of the problem:

• blocking inflammation indiscriminately may hinder essential repair mechanisms;
• allowing it to unfold without intervention may lead to dangerous inflammatory escalation.

DARLENE is built on this nuanced understanding: the aim is not to suppress inflammation, but to modulate it — tempering its harmful components while preserving its beneficial effects.

An Unmet Therapeutic Need

In clinical practice, there is currently no validated medication specifically targeting inflammation after intracerebral haemorrhage. Corticosteroids have not shown benefit, and previous anti‑inflammatory trials have not demonstrated convincing clinical efficacy.

This lack of therapeutic options stands in stark contrast with the major role played by cerebral oedema in patient outcomes. DARLENE was born from this observation: a key determinant of prognosis remains therapeutically unaddressed.

DARLENE Within the TIPITCH Trajectory: An Integrated Approach

The DARLENE study fits perfectly within the global logic of TIPITCH, which targets the different stages of intracerebral haemorrhage:

• upstream, limiting vascular rupture and haematoma expansion;
• intermediate, reducing blood toxicity and promoting its evacuation;
• later, targeting inflammation and optimising repair mechanisms.

DARLENE corresponds to this third pillar. It complements early‑stage strategies by addressing a slower process that is equally decisive for long‑term functional outcome.

A Strong Biological Rationale: The NRF2 Pathway

The therapeutic choice evaluated in DARLENE is based on years of translational research, from experimental models to human observations. These studies highlight the central role of the NRF2 pathway in regulating post‑haemorrhagic inflammation.

NRF2 contributes both to:

• limiting excessive inflammatory mechanisms,
• supporting haematoma resolution and brain tissue repair.

The study evaluates the effect of an NRF2 agonist, Diroximel fumarate, using a drug‑repositioning strategy. Already authorised for other indications, it benefits from extensive safety data — a major asset for future potential clinical use.

A Clinical Study Designed Around Biological Time

DARLENE is a Phase 2B randomised, multicentre clinical trial, sponsored by CHU Lille and involving several French centres specialised in stroke care. Nearly 200 patients with spontaneous intracerebral haemorrhage will be enrolled.

One of the study’s most innovative aspects is the 21‑day treatment duration. This timeframe was defined to accompany the full course of inflammation, from oedema development to tissue repair.

The primary endpoint is the radiological measurement of cerebral oedema volume, supplemented by clinical criteria and close monitoring of treatment tolerance.

A Scientific and Human Innovation

Beyond its therapeutic approach, DARLENE stands out for its thoughtful organisation and follow‑up. The protocol benefited from the input of patients who had themselves experienced intracerebral haemorrhage, enabling adjustments to monitoring procedures and evaluation tools to reflect real‑world patient experience.

Furthermore, biological samples collected during the study will constitute a biobank, paving the way for future research on inflammation mechanisms and biomarkers of treatment response.

Long Term Prospects, Without Premature Promises

If DARLENE yields positive results, it will represent a major proof of concept, paving the way for a larger Phase 3 trial. The long‑term objective is clear:
to develop an accessible treatment that complements existing strategies and sustainably improves patient outcomes.

More broadly, DARLENE embodies the philosophy of TIPITCH:
challenging the perceived inevitability of intracerebral haemorrhage through rigorous, innovative, patient‑centred science.

At the International Stroke Conference 2025 #ISC2025, experts shared major advances in the treatment of deep intracerebral haemorrhage—an issue at the very heart of our project.

🔹 Minimally invasive surgery: what progress is being made?
– MISTIE and MIPS, two innovative techniques for haematoma evacuation, show promising results but still require further study to demonstrate a clear functional benefit.
– Decompressive surgery, assessed in the SWITCH trial, remains a debated option with no confirmed improvement in six‑month recovery outcomes.

🔹 What levers for better medical management?
Professor Charlotte Cordonnier, lead investigator of TIPITCH, emphasised the importance of combined strategies to limit haematoma expansion, reduce cerebral oedema, and promote clot resolution. New avenues are emerging, particularly around modulation of the inflammatory response.

These advances strongly align with our mission: improving the treatment of haemorrhagic stroke and optimising care pathways.

📌 The key challenge for upcoming studies?
Identifying the patients most likely to benefit from these combined approaches and refining evaluation criteria.

👉 We will continue to share major developments on this topic.

💡 Artificial intelligence serving diagnosis and monitoring of haemorrhagic stroke

As part of his presentation on “Imaging: diagnosis and monitoring”, Professor Grégoire Boulouis (CHRU Tours) highlighted the central role of imaging and answered questions on artificial intelligence, emphasising the work underway within the TIPITCH project:

“Within the TIPITCH project, we are leading working groups in Tours to develop a large-scale imaging infrastructure and database. The aim is to gather a sufficiently large volume of data to train artificial intelligence algorithms. Structuring these data is a crucial step to enable efficient automated analysis. As of today, such a tool does not yet exist, but it is a major objective we hope to achieve.”

💡 Transforming the management of haemorrhagic stroke

Speaking on “Treatments: future therapeutic targets”, Professor Charlotte Cordonnier (CHU Lille), lead investigator of RHU TIPITCH, highlighted the major shift currently taking place in the management of haemorrhagic stroke:

“Thanks to the work undertaken, particularly within TIPITCH, we are moving away from an approach characterised by nihilism and self‑fulfilling pessimism towards a more optimistic vision based on a multidisciplinary strategy. As illustrated during this session, the management of cerebral haemorrhage now relies on close collaboration between neurologists, neuroradiologists, neurosurgeons and neuro‑intensive care specialists. Imaging and invasive treatments are integrated from the moment the patient is admitted, within a multimodal care environment that significantly improves overall management.”

👏 Congratulations to Charlotte Cordonnier, whose presentation generated strong interest, as reflected in the many questions that followed!
