Acute ischemic stroke is a leading cause of death worldwide, and intravenous thrombolysis with recombinant tissue plasminogen activator rt-PA within 4.5 hours of symptom onset is the most effective treatment currently available. However, some patients experience stroke progression and early reocclusion after thrombolysis, which can worsen neurological outcomes. This trial evaluates whether early antiplatelet therapy with oral aspirin, given soon after thrombolysis, can improve recovery without increasing bleeding risks. The study randomly assigns patients to receive either early oral aspirin within 3 hours of starting intravenous thrombolysis or a placebo, alongside the best medical care based on current guidelines. Aspirin is administered as a 300 mg dose, either chewed or given via nasogastric tube if swallowing is difficult. The trial includes a control group receiving placebo under similar conditions to compare outcomes. This is a Phase 3, multicenter, quadruple-blind, randomized clinical trial. During the study, participants will be closely monitored for neurological status and functional recovery using the modified Rankin scale at 30 and 90 days after stroke, as well as other assessments like NIH Stroke Scale scores within the first week. Researchers will track early neurological changes and safety outcomes such as intracranial hemorrhage. Follow-up will include evaluations at multiple time points up to 90 days post-stroke to determine the effects of early antiplatelet treatment on stroke recovery.

Researchers are evaluating the effects of a medicine called BI 690517 combined with empagliflozin in adults with chronic kidney disease CKD who are at risk of their kidney condition getting worse. The study includes people with or without type 2 diabetes and those who may already be taking medicines like angiotensin converting enzyme inhibitors ACEi, angiotensin receptor blockers ARB, or sodium-glucose cotransporter-2 inhibitors SGLT2i. The goal is to understand if adding BI 690517 can help delay worsening kidney function, hospitalizations due to heart failure, or cardiovascular death. After a run-in period where all participants take empagliflozin and other standard medications, participants are randomly assigned to receive either BI 690517 tablets or placebo tablets once daily alongside empagliflozin. The run-in period confirms that participants are stabilized on empagliflozin before randomization. The treatment phase continues for about three to four years until enough kidney or heart-related events have occurred to compare outcomes between the two groups. During the study, participants visit the study site about five times in the first six months and then every six months thereafter. At these visits, health is regularly checked through blood and urine tests, blood pressure and weight measurements, kidney function monitoring, and collection of any side effect information. The main outcome measured is the time until the first occurrence of kidney disease progression, hospitalization for heart failure, or cardiovascular death.

This research aims to evaluate whether combining cold atmospheric plasma CAP therapy with endovascular intervention can speed up wound healing and improve safety in adults aged 18 to 80 with diabetic foot ulcers DFUs complicated by lower extremity arterial blockage. The study compares CAP treatment plus standard care to placebo sham CAP plus standard care to investigate if CAP leads to greater ulcer area reduction and fewer adverse local symptoms. The trial is randomized, double-blind, and placebo-controlled to ensure reliable results. Participants receive either active CAP therapy or sham CAP therapy once daily for 10 days following successful balloon angioplasty of infrapopliteal arteries. CAP treatment involves applying CAP-activated gas for 25 minutes per session using a specialized device. Sham CAP uses identical equipment without plasma activation to maintain blinding. All participants continue to receive guideline-based standard diabetic foot ulcer care throughout the study. During the study, participants undergo daily wound assessments to measure ulcer size, infection signs, and pain levels. Quality of life questionnaires EQ-5D and SF-12 are completed at the start and at Week 4. The main outcome measured is the change in ulcer area from baseline through Day 10 and Week 4. Researchers also monitor pain scores, time to early healing, quality of life changes, and local adverse events. The study follow-up period is 4 weeks after randomization to evaluate efficacy and safety outcomes.

Critical limb ischemia is a severe form of peripheral arterial disease often seen in patients with diabetes, leading to painful ulcers, tissue damage, and sometimes amputation. This study investigates the use of cold atmospheric plasma CAP combined with endovascular intervention to treat diabetic foot ulcers complicated by lower extremity arterial occlusion. The study aims to assess whether this combination can improve healing outcomes and provide safer, more effective care for patients facing high risks from current therapies. Participants will receive successful infrapopliteal angioplasty to restore blood flow in affected arteries. They will then be randomly assigned to receive either CAP therapy or a sham procedure. CAP treatment involves daily sessions for the first five days, followed by every other day for a total of 13 sessions, each lasting about 25 minutes. The CAP device delivers ozone-rich plasma followed by nitric oxide-rich plasma to promote disinfection and healing. The sham procedure mimics the treatment sounds without producing plasma, ensuring blinding. Throughout the 21-day study period, researchers will monitor ulcer size, time to reduction, infection signs, pain levels, and quality of life using questionnaires. Safety will be tracked by recording skin irritation, bleeding, and burning sensations. Assessments include vascular imaging and clinical evaluations to measure treatment effects on wound healing and blood flow, with the goal of gathering evidence for CAPs role alongside endovascular techniques in diabetic foot care.
