About the research
There are 2 arms to this study.
Arm 1: Participants undergoing coronary angiography for stable or acute coronary disease presentations and eligible for percutaneous coronary intervention (PCI) will be imaged with OCT-NIRAF at baseline and with CCTA 12 months apart to demonstrate that:
1. NIRAF coronary artery signal level (patient, artery, lesion basis) is correlated with the severity of coronary artery disease.
2. NIRAF coronary artery signal level is a predictor of plaque progression on a per participant, per artery, or per lesion basis.
Arm 2: Participants undergoing coronary angiography for stable or acute coronary disease presentations and eligible for percutaneous coronary intervention (PCI) will be imaged with OCT-NIRAF following injection of LUMISIGHT. The primary objective is to assess the feasibility of intravascular detection and spatial localization of LUMISIGHT during routine coronary imaging.

Arm 1:
This study will provide preliminary data on the clinical value of intracoronary OCT-NIRAF imaging in participants undergoing invasive coronary angiography in the cardiac catheterization laboratory. This is a single site, prospective feasibility study where 40 study subjects undergoing coronary angiography for stable or acute coronary disease presentations and eligible for percutaneous coronary intervention (PCI) will undergo intravascular imaging, including standard-of-care IVUS and then OCT-NIRAF pullback imaging conducted during an iodinated contrast flush. Patients will be consented prior to catheterization. Participant characteristics such as age, sex, BMI, and current medication regimen will be recorded. Standard of care blood chemistry will be reviewed and lab values from the subject's electronic medical records will be input into the study's Case Report Form when available. A complete medical history and data regarding prescribed cardiac medications also be transcribed from the EMR into the CRF.
Coronary Angiography will be performed. For participants for whom coronary angiography provides a clinical indication for intravascular imaging or PCI without any exclusion criteria, 40 study participants will undergo intravascular imaging, including standard-of-care IVUS and then research study OCT-NIRAF pullback imaging, conducted during an iodinated contrast flush.
Intravascular imaging of the PCI target artery will be done prior to PCI unless the interventional cardiologist determines that intervention is required to deliver the imaging catheters. The other major coronary arteries may also be imaged by IVUS and OCT-NIRAF based on clinical assessment of the appropriateness of imaging by the interventional cardiologist.
In addition, participants will obtain a baseline coronary CTA at MGH, using standard clinical protocols in the MGH Department of Radiology.
Follow up imaging: After 12 months (+/- 28 days), participants will undergo a follow-up study coronary CTA, to assess for plaque progression compared to the baseline coronary CTA.
Follow up: Participants will undergo standard-of-care cardiology follow-up and medical record review follow-up by study staff at 1 month (+/- 7 days), 6 months (+/- 28 days), and 1 year (+/- 28 days). After completion of the CCTA and final telephone 12-month follow-up, patients will be released from the study.
Arm 2:
This study will provide preliminary data on the clinical value of intracoronary OCT-NIRAF imaging following LUMISIGHT injection in participants undergoing invasive coronary angiography in the cardiac catheterization laboratory. This is a single site, prospective feasibility study where 30 study subjects undergoing coronary angiography for stable or acute coronary disease presentations and eligible for percutaneous coronary intervention (PCI) will undergo intravascular imaging, including standard-of-care IVUS and then OCT-NIRAF pullback imaging conducted during an iodinated contrast flush. Patients will be consented prior to catheterization. Participant characteristics such as age, sex, BMI, and current medication regimen will be recorded. Standard of care blood chemistry will be reviewed and lab values from the subject's electronic medical records will be input into the study's Case Report Form when available. A complete medical history and data regarding prescribed cardiac medications also be transcribed from the EMR into the CRF.
LUMISIGHT injection will occur 2-12 hours prior to intravascular imaging procedure. Coronary Angiography will be performed. For participants for whom coronary angiography provides a clinical indication for intravascular imaging or PCI without any exclusion criteria, 30 study participants will undergo intravascular imaging, including standard-of-care IVUS and then research study OCT-NIRAF pullback imaging, conducted during an iodinated contrast flush.
Intravascular imaging of the PCI target artery will be done prior to PCI unless the interventional cardiologist determines that intervention is required to deliver the imaging catheters. The other major coronary arteries may also be imaged by IVUS and OCT-NIRAF based on clinical assessment of the appropriateness of imaging by the interventional cardiologist.
Who may be able to participate?
The list below is the sponsor’s full registry wording. It can include conditions, prior treatment, test results and other requirements. A match in search does not mean you qualify.
