The PASSIVATE-CAP study is an investigator-initiated, prospective, randomized, multicenter, open-label superiority trial focusing on acute coronary syndrome (ACS) patients with nonflow-limiting vulnerable plaques in nonculprit vessels. In this study, eligible patients were randomized at a 1:1 ratio into two groups: patients who received guideline-directed medical therapy (GDMT) and patients who received GDMT combined with a drug-coated balloon (DCB). In this study, the use of PCSK9 inhibitors was limited to inclisiran. The primary endpoint was the minimal lumen area of the target lesion 1 year after randomization. The secondary endpoints encompass a range of factors, including the proportion of patients with vulnerable plaques in the target vessel, fibrous cap thickness, lipid core arc of the target lesion, minimal lumen area of the target vessel, and extent of LDL-C reduction in patients treated with inclisiran.
1,488 studies on the registry are indexed under Acute Coronary Syndrome; 273 are open to participants now.
This study's planned enrollment of 140 is below the median of 200 across 865 interventional studies indexed under Acute Coronary Syndrome.

Age ≥ 18 years Diagnosis of ACS with the intention to undergo ICA There exists a nonculprit lesion characterized by a single diameter stenosis greater than 50% in the major coronary artery segments (with diameters ranging from 2.75 to 4 mm).
QFR value > 0.8 The OCT examination suggests vulnerable plaques with a fibrous cap thickness of \< 65 µm, along with at least two of the other three OCT criteria Minimum lumen area \<3.5 mm² Lipid core angle >180° Presence of macrophages lesion length ≤30 mm Provide greater than 1 year
Exclusion Criteria:
Patients with three or more target lesions or with two target lesions in the same coronary artery left main stem lesions Ostial lesions Thrombotic lesions Severe calcification or angulated lesions True bifurcation lesions requiring stent implantation Advanced heart failure ( III-IV) Ischemic stroke in the past 6 months or any history of cerebral hemorrhage at any time Severe valve disease or valve disease that may require surgical or percutaneous valve replacement Coronary artery anatomy obstructs the complete imaging of the segment of interest (including at least 5 mm beyond the narrow ends).
Diffuse coronary artery disease or the presence of ≥1 untreated nonculprit lesion (nonculprit blood flow-restricting lesion planned for staged PCI).
History of myocardial infarction, CABG, or PCI Coronary artery anatomy not suitable for PCI The potential comorbidity that may impact the completion of the trial process. The planned major surgery requires discontinuation of DAPT. History of PCSK9 inhibitor (such as evolocumab or alirocumab) use within 90 days prior to the first study visit.
Exposed to Inclisiran or any other non-PCSK9 monoclonal antibody targeted treatment within the 2 years preceding the initial study visit, whether as an drug or a marketed medication.
History of allergy to the investigational drug, its , or other siRNA drugs Females of , defined as all female subjects physiologically capable of becoming pregnant, unless they are using effective during the administration of the investigational drug
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Procedure: GDMT+DCB
Preventive Intervention on Eligible Vulnerable Plaques Using DCB
Minimum luminal area
Minimum luminal cross-sectional area of the target lesion measured 1 year after randomization.
Time frame: 1 year
proportion of patients with vulnerable plaques in the target vessel
proportion of patients with vulnerable plaques in the target vessel
Time frame: 1 year
fibrous cap thickness
Fibrous cap thickness
Time frame: 1 year
lipid core arc
The lipid core arc as visualized on optical coherence tomography (OCT) refers to the angular extent and characteristics of the lipid-rich region within an atherosclerotic plaque. On cross-sectional OCT imaging, the lipid core appears as an area with high backscattering and high signal attenuation, distinguishing it from the surrounding fibrous or calcified plaque components. The key features of the lipid core arc include the arc angle (the angular extent of the lipid core in degrees), the arc thickness (the maximal radial thickness of the lipid core), and the arc location (the position of the lipid core relative to the lumen and other plaque components).
Time frame: 1 year
Changes in LDL-C
The degree of changes in patients' LDL-C (low-density lipoprotein cholesterol) levels before and after treatment
Time frame: 1 year
Target vessel failure
A composite endpoint event encompassing cardiac death, target vessel myocardial infarction, and ischemia-driven target vessel revascularization.
Time frame: 1 year
