Trial Summary

What is the purpose of this trial?

This trial is testing asundexian, a new medicine that prevents blood clots, in people who had a non-heart-related stroke or high-risk mini-stroke. The goal is to see if it works better at reducing future strokes without increasing bleeding risks. Asundexian is developed by Bayer AG and might prevent thrombosis without increasing bleeding.

Do I need to stop my current medications to join the trial?

The trial does not specify if you need to stop your current medications. However, it mentions that participants will receive asundexian or placebo in addition to standard antiplatelet therapy, suggesting you may continue your current antiplatelet medications.

What data supports the idea that the drug Asundexian for Stroke Prevention is an effective treatment?

The available research does not provide any data on Asundexian for Stroke Prevention. The studies listed focus on other treatments and conditions, such as bone formation in rabbits, shoulder pain, spinal stabilization, blood loss in surgery, and shoulder pain management. Therefore, there is no information here to support the effectiveness of Asundexian for Stroke Prevention. ^{1 2 3 4 5}

What safety data exists for Asundexian for stroke prevention?

The provided research does not contain any safety data for Asundexian (BAY2433334) or its use in stroke prevention. The studies focus on other medications and conditions, such as benign prostatic hyperplasia and hypertension, and do not mention Asundexian or related treatments. ^{6 7 8 9 10}

Is the drug Asundexian a promising treatment for stroke prevention?

The information provided does not directly address the effectiveness of Asundexian for stroke prevention. The articles focus on other treatments like aspirin and NXY-059, and discuss general challenges in developing effective stroke treatments. Therefore, we cannot conclude if Asundexian is promising based on this information. ^{11 12 13 14 15}

Findings from Research

In a study involving 24 rabbits undergoing spine fusion, daily subcutaneous injections of abaloparatide resulted in a 100% fusion rate compared to only 45% in the control group, indicating its strong efficacy in promoting spinal fusion.

Radiographic analysis showed that abaloparatide significantly increased bone formation and quality, with higher bone volume and improved trabecular structure, suggesting it enhances the biological processes necessary for successful spinal fusion.

In a randomized, double-blind clinical trial involving 125 patients with referred shoulder pain, applying a force to the C5 vertebra using a mechanically assisted instrument (MAI) significantly improved internal rotation strength after 6 months (P = 0.04).

While the treatment cohort experienced a reduction in the frequency of extreme shoulder pain (from weekly to monthly), there was no significant change in the severity of pain or other functional outcomes compared to the placebo group.

The use of an ESP block during minimally invasive spinal surgery significantly reduced opioid consumption by 37.7% in the first 48 hours post-surgery, indicating its efficacy in pain management.

Patients receiving the ESP block reported lower pain levels (measured by VAS) and improved short-term outcomes (PROST scores) compared to the placebo group, although there were no significant differences in blood loss or wound healing complications.

In a study involving 100 patients undergoing lumbar spine fusion surgeries, batroxobin and its combination with tranexamic acid significantly reduced both intraoperative and postoperative blood loss compared to a placebo.

The mean intraoperative blood loss was lowest in the batroxobin group (268.32 mL) and the combination group (256.96 mL), indicating their effectiveness, while no significant differences were found in blood transfusion needs or complications like deep vein thrombosis.

In a clinical trial with 73 participants suffering from rotator cuff related shoulder pain, omega-3 polyunsaturated fatty acids (PUFAs) showed a modest improvement in pain and disability outcomes, particularly noted in the Shoulder Pain and Disability Index (SPADI) at 3 months.

However, there was no significant difference in the primary outcome, the Oxford Shoulder Score (OSS), between the omega-3 group and the placebo group at the 2-month mark, indicating that while there may be some benefits, they are not robust.

In a study of 101 patients with benign prostatic hyperplasia (BPH), a 16-week placebo treatment resulted in a significant 24% decrease in symptom scores and a 14% increase in peak flow rate, highlighting the substantial impact of placebo effects in BPH management.

The maximal placebo effect, which can lead to about a 40% reduction in symptoms, typically occurs within the first four to six months, suggesting that the timing of treatment initiation is crucial for evaluating the efficacy of new therapies.

Dutasteride significantly improves urinary symptoms and reduces prostate volume in men with benign prostatic hyperplasia (BPH), outperforming placebo in clinical trials involving nine studies with men aged 40 and over.

While dutasteride is effective, it is associated with a higher rate of drug-related adverse events; however, combining it with tamsulosin leads to even greater symptom relief compared to tamsulosin alone.

In a study of 19 patients with mild to moderate essential hypertension and intermittent claudication, once-daily doxazosin significantly reduced both systolic and diastolic blood pressure after 14 weeks, with mean blood pressures decreasing from 170/100 mm Hg to 161/93 mm Hg.

Doxazosin was effective in normalizing blood pressure in 75% of patients and improved the severity of hypertension in 81.3% of patients, with only mild side effects reported, indicating a favorable safety profile.

The Prostate Cancer Prevention Trial demonstrated that finasteride reduced the prevalence of prostate cancer by 25% over 7 years in men over 55, indicating its potential as a chemopreventive agent.

While finasteride showed a reduction in overall prostate cancer rates, there was an increase in higher-grade cancers, suggesting the need for careful consideration of trial design biases and the clinical significance of the cancers prevented.

In a study of 205 patients with Benign Prostatic Hyperplasia (BPH) over 12 weeks, alfuzosin significantly reduced symptoms and improved urinary flow compared to placebo.

Alfuzosin was found to be safe, with no significant differences in adverse events or withdrawals between the alfuzosin and placebo groups, indicating it has a favorable safety profile.

In a study involving 5028 patients with acute ischemic stroke, NXY-059 did not show any significant benefit in reducing disability compared to placebo, with similar outcomes on the modified Rankin scale after 90 days.

NXY-059 also failed to reduce the incidence of intracranial hemorrhages associated with the use of alteplase, indicating it is ineffective for treating acute ischemic stroke within 6 hours of symptom onset.

Aspirin is effective for the treatment and prevention of ischemic stroke, but the required dosage varies based on the specific indication, with higher doses (160-325 mg) needed for acute ischemic stroke and atrial fibrillation (325 mg).

Low-dose aspirin (50-81 mg daily) may not be sufficient for some patients at risk of ischemic stroke, highlighting the need for individualized dosing based on clinical guidelines and patient conditions.

In a study involving 372 asymptomatic patients with carotid stenosis, aspirin did not significantly reduce the risk of ischemic events compared to a placebo over a median follow-up of 2.3 years.

The annual rate of ischemic events was similar between the aspirin group (11.0%) and the placebo group (12.3%), indicating that aspirin does not provide a long-term protective effect in this patient population.

No neuroprotective drug has proven effective for treating acute ischaemic stroke in clinical settings, despite success in animal studies, highlighting a significant gap in translating research to human treatment.

Following newly established guidelines for drug development, such as thorough dose-response evaluations and functional testing, may improve the chances of success for compounds like NXY-059, which is currently in clinical development.

Current guidelines recommend oral anticoagulants for patients with cardioembolic strokes and antiplatelet agents, like aspirin, for those with ischemic strokes due to atherothrombosis, highlighting the importance of tailored long-term treatment.

Meta-analyses suggest that the effectiveness of aspirin in preventing vascular events is consistent across various doses, leading to a recommendation for lower doses (50-325 mg daily) due to their better safety profile.
