Q: Who can participate in NCT05882708?

Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.

Q: How do I contact the trial site for NCT05882708?

Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.

Q: Is participating in a clinical trial safe?

Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.

Effect of Heart Rate Control With Ivabradine on Hemodynamic in Patients With Sepsis: a Prospective, Multicenter, Randomized Controlled Trial

Effect of Heart Rate Control With Ivabradine on Hemodynamic in Patients With Sepsis (NCT05882708) is a Phase 4 interventional studying Sepsis and Ivabradine, sponsored by Second Affiliated Hospital of Guangzhou Medical University. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

Sepsis, a life-threatening syndrome, is often accompanied by tachycardia in spite of adequate volume resuscitation to correct hypovolemia and vasopressor medication to correct hypotension. Recently, relevant studies have shown that sustained tachycardia in sepsis was also related to high mortality, and appropriate control of heart rate could improve prognosis. Ivabradine reduces heart rate directly without a negative inotropic effect through inhibition of the If ionic current，which is absent from the traditional rate control drug (beta-blockers). This is a prospective, multicenter, randomized, open label study designed to compare ivabradine with placebo on the difference of heart rate and haemodynamics in patients with sepsis.

What Stage of Research Is This?

Phase 4 studies happen after a treatment has been approved by the FDA. They monitor long-term safety, real-world effectiveness, and any rare side effects that only emerge in larger populations over longer periods. Phase 4 results sometimes lead to label changes, additional warnings, or — rarely — withdrawal of approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 172 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Sepsis subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

Who May Be Eligible (Plain English)

Who May Qualify: 1. Adult patients aged 18 years or above. 2. Being treated in an intensive care unit. 3. Sepsis is diagnosed according to Sepsis-3.0 criteria, which is defined as patients requiring antimicrobial agents due to confirmed or suspected infection, acute increase in the SOFA score at least 2 points. 4. Mean arterial pressure (MAP) is maintained ≥65 mmHg with adequate volume resuscitation and vasopressor therapy. Volume resuscitation is considered adequate when Central Venous Pressure (CVP) \> 8mmHg, global end-diastolic volume index (GEDI) \> 680ml/m2 and resting inferior vena cava (IVC) diameter \> 1.5cm. 5. Patients are in a relatively stable period of hemodynamics, as defined that the targe mean arterial pressure are maintained with the same dosage of vasopressors for at least 2 h. 6. Sinus rhythm with heart rate ≥ 95bpm maintain for at least 2 hours but less than 72 hours. Who Should NOT Join This Trial: 1. Patients who had received ivabradine therapy or known allergy to it prior to randomization. 2. Patients with severe liver dysfunction (Child-C grade). 3. Patients with a history of pre-existing chronic renal failure (glomerular filtration rate less than 15 ml/min/1.73 m2), except patients treated with continuous renal replacement therapy (CRRT). 4. Patients with known seizure disorder. 5. Patients with any contraindication to gastrointestinal drug administration. 6. Pregnant or lactating patients. 7. patients requiring the use of potent cytochrome CYP3A4 inhibitors such as antifungals of the azole-type (specifically ketoconazole and itraconazole), macrolide antibiotics (specifically clarithromycin and erythromycin) and HIV protease inhibitors (specifically nelfinavir and ritonavir). 8. Patients with active bleeding; ...See full criteria on ClinicalTrials.gov Always talk to your doctor about whether this trial is right for you.

Treatments Being Tested

DRUG

Ivabradine

After randomization, the starting dose of ivabradine, 5mg, is given via the gastrointestinal tract every 12 hours. Heart rate control ranged from 70 to 94 bpm. Ivabradine was maintained until 96 hours after initiation of therapy. Beyond this period, the decision to continue ivabradine is left to the discretion of the treating intensivist. During the drug intervention period, heart rate is assessed before each dose. Ivabradine is tapered or discontinued if the heart rate is lower than the target rate; If the heart rate remains ≥95 bpm after 48 hours, the dose is increased to 7.5mg. If a heart rate of 95 or more bpm recurs after discontinuation during the intervention period, treatment with ivabradine can be resumed. Furthermore, Ivabradine is also discontinued at any time in the presence of severe liver impairment, malignant arrhythmia, cardiac conduction block, allergy, the need to take drugs with potentially harmful effects of ivabradine.
