What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing whether milvexian can help prevent another stroke in people who have already had one by stopping blood clots from forming. Milvexian may reduce the risk of stroke without significant bleeding.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it mentions that current or planned antiplatelet treatment is allowed. If you are taking acetyl salicylic acid (ASA), it should be limited to a low dose of 75 to 100 mg per day.

What makes the drug Milvexian unique for stroke treatment?

Milvexian is unique because it is an oral anticoagulant that targets Factor XIa, a specific protein involved in blood clot formation, which may offer a new approach to preventing strokes compared to traditional anticoagulants that target other pathways. ^{1 2 3 4 5}

Are You a Good Fit for This Trial?

This trial is for adults who've recently had a mild ischemic stroke or high-risk TIA, with specific criteria like NIHSS score <=7 and an ABCD2 Score >=6. They must be able to take low-dose antiplatelet medication and not be at risk of pregnancy. Exclusions include prior serious brain bleeds, strokes from heart problems needing blood thinners, other non-athero-thrombotic causes, bleeding risks, liver disease, or allergies to the study drug.

Inclusion Criteria

I had a stroke or TIA with specific conditions met.

Willing and able to adhere to the lifestyle restrictions specified in this protocol

I am not pregnant, breastfeeding, nor planning to become pregnant soon after the study ends.

Exclusion Criteria

My stroke or TIA was caused by a reason other than blood clot issues.

I had a brain bleed over a year ago and received proper treatment for it.

My stroke or TIA was caused by a clot from the heart, and I need blood thinners.

What Are the Treatments Tested in This Trial?

Interventions

• Milvexian
• Placebo

Trial Overview The LIBREXIA-STROKE trial is testing if Milvexian can prevent another stroke better than a placebo (a dummy pill). Participants are chosen randomly to receive either Milvexian or placebo within 48 hours after their initial stroke or TIA symptoms start.

How Is the Trial Designed?

Group I: Milvexian Experimental Treatment 1 Intervention

Participants after an acute ischemic stroke or high-risk transient ischemic attack (TIA) who are receiving antiplatelet therapy standard-of-care (SAPT \[single antiplatelet therapy\] or DAPT \[dual antiplatelet therapy\]) will receive milvexian 25 milligrams (mg), orally, twice daily.

Group II: Placebo Placebo Group 1 Intervention

Participants after an acute ischemic stroke or high-risk TIA who are receiving antiplatelet therapy standard-of-care (SAPT or DAPT) will receive placebo orally twice daily.

Published Research Related to This Trial

Mexidol shows promise in post-stroke rehabilitation due to its broad effects on various disorders, particularly when used in long-term therapy to improve motor, cognitive, and emotional functions.

A tailored approach to rehabilitation, incorporating Mexidol and other treatments, is recommended to enhance patient outcomes, but further high-quality clinical studies are needed to confirm its efficacy.

Dalfampridine extended release (D-ER) was generally well tolerated in 83 participants with chronic post-ischemic stroke deficits, with no new safety concerns identified compared to previous trials.

The study found that D-ER significantly improved walking speed compared to placebo, indicating potential benefits for lower extremity sensorimotor function in stroke survivors.

In a multicenter, randomized, placebo-controlled study involving 252 acute ischemic stroke patients, edaravone showed a significant improvement in functional outcomes compared to placebo, as measured by the modified Rankin Scale (p = 0.0382).

Edaravone acts as a neuroprotective agent by inhibiting vascular endothelial cell injury and reducing neuronal damage, suggesting its potential as an effective treatment for acute ischemic stroke when administered within 72 hours of onset.

The combination of atomoxetine and intensive speech therapy was safe and feasible for four adult patients with post-stroke aphasia, with no adverse effects reported during the study.

All patients showed improvements in language function, with significant increases in scores on language assessments and enhanced cortical blood flow in areas surrounding the brain lesions, indicating potential therapeutic benefits.

Dengzhanhua injection demonstrated a significantly higher total effective rate (92.0%) compared to fufangdanshen injection (75.8%) in treating acute cerebral infarction among 100 patients, indicating its superior efficacy.

The treatment with dengzhanhua injection also led to significant improvements in hemorrheology and lipemia without any adverse reactions, suggesting it is a safe option for patients.
