About this study

Official title: Intraoperative Use of Intravenous Indocyanine Green (ICG) to Assess Ovarian Perfusion Using Infrared Imaging: A Feasibility Pilot Study

To assess the feasibility of using intravenous ICG to characterize the vascular perfusion of ovaries during gynecologic surgery

Read the detailed description

The purpose of this study is to determine the feasibility of intravenous ICG administration to facilitate assessments of ovarian vascular perfusion. Historically, assessment of ovarian perfusion has been performed visually or via ultrasound with Doppler evaluation. In patients with ovarian endometriomas, evidence of ovarian interstitial microvascular injury has been demonstrated similarly by the presence of low flow and high RI. The use of ICG to evaluate ovarian perfusion specifically has not been reported. The use of ICG for intraoperative perfusion assessment of the ovary could provide more information about the health of the ovary and inform the surgical approach to ovarian pathology.

ICG will be injected intravenously to assess ovarian perfusion in the presence or absence (control) of pathology. Near infrared fluorescence imaging will be used to illuminate the ICG. The extent of perfusion will be determined using digital imaging software.

  • ICGDrug

    Also called Indocyanine green (ICG)

    Indocyanine green (ICG) is a Food and Drug (FDA)-approved tricarbocyanine dye that is fluorescent under near-infrared (NIR) light. ICG solutions for injection often contain sodium iodide. ICG is water soluble and when introduced intravenously, it is bound by plasma proteins, namely albumin. The intravascular half-life of ICG is 3-4 minutes with rapid hepatic clearance.

Administration of ICGExperimentalICG will be injected intravenously to assess ovarian perfusion in the presence or absence (control) of pathology. Near infrared fluorescence imaging will be used to illuminate the ICG. The extent of perfusion will be determined using digital imaging software. ICG will be stored at the NM Investigational Pharmacy and administered intravenously by the anesthesiologist at the direction of the surgeon during surgical procedure.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Assessment of ovarian perfusion after ICG administration via fluorescent imaging

    The investigators will be assessing the feasibility of using intravenous ICG to characterize the vascular perfusion of ovaries by imaging. During surgery ICG will be administered intravenously via a peripheral or central line at the direction of the surgeon by the anesthesiologist. The injected amount will be a 3 mL solution of reconstituted ICG that contains a 7.5 mg dose of ICG. This will be followed by a 10 mL bolus of normal saline for injection per the manufacturer's recommendation. The total dose of dye injected should not exceed 2 mg/kg.

    Visibility of the ICG fluorescence should occur within 1-2 minutes with a duration of 20-120 minutes.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing ICG in people with Fibroid Uterus and Endometriosis, run by Northwestern University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Assessment of ovarian perfusion after ICG administration via fluorescent imaging (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Apr 2023.
