About this study

Official title: Near InfraRed Fluorescence Imaging of Lymphatic Transport Using Indocyanine Green

In this phase 1 study, the lymphatic transport will be examined using Near InfraRed Indocyanine Green fluorescence imaging (NIR-ICG) of the upper extremities in healthy individuals using a MultiSpectral Imaging System (MSImager).

Read the detailed description

Lymphedema from various etiologies (i.e. infection, cancer, surgery, and rheumatoid arthritis) remains a major health concern. Efforts to develop effective treatments for this condition have been limited by the absence of quantitative outcome measures for lymphatic function. Published articles have supported the fact that human lymphatic contractions can be readily visualized after intradermal administration of micrograms of Indocyanine Green using laser-induced fluorescence. The use of lasers imposes a risk of eye injury that requires protective eyewear. To address the risk of laser-induced injury, an imaging system was developed by Drs. Ronald Wood and Jay Reeder in a collaborative effort at the University of Rochester. In place of a laser, this system utilizes a tungsten-halogen lamp fitted with a bandpass filter and a multispectral camera for real-time image acquisition and display. This phase 1 study will examine the validity and reliability of this instrument to measure lymphatic transport, contractions, and pressure in the arms of healthy research subjects and establish baseline parameters for subsequent evaluation of rheumatoid arthritis patients in later studies. Indocyanine Green is a dye that has been used clinically for over 50 years to evaluate hepatic clearance, cardiovascular function testing, and retinal angiography. Indocyanine Green has typically been administered intravenously at concentrations of 2.5 mg/ml at total doses of 25 mg in adults. In this study, intradermal administration of micrograms of Indocyanine Green will be used to establish useful dose ranges and concentrations. The dosage regimen for this study is based on prior demonstrations in published articles of successful noninvasive imaging of lymphatic contractions after intradermal administration of microgram amounts of Indocyanine Green.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Indocyanine GreenDrug

    Also called ICG, IC-Green, 17478-701-02

    A trained physician will inject 0.1 ml of Indocyanine Green into the web spaces of the hands in both upper extremities. Subjects may have up to five study visits to confirm feasibility, safety, and reproducibility.

  • MultiSpectral Imaging SystemDevice

    Also called MSImager

    Once the Indocyanine Green is injected, the contrast is expected to fluoresce underneath the MultiSpectral Imaging System. Multispectral video and still images will be recorded at the study visits.

Study groups in NCT02680067
Study groupRoleWhat they receive
Developmental arm - Healthy or rheumatoid arthritis subjectsExperimentalSubjects in the developmental arm will have a minimum of two study visits to determine the optimal conditions for visualizing lymphatic transport in the upper extremities. Concentrations of 0.1 mg/ml of Indocyanine Green (ICG) will be injected intradermally into the web spaces of the hands in both upper extremities. Multispectral video and still images will be recorded using the MultiSpectral Imaging System (MSImager). An ultrasound of the upper extremities may be performed after the ICG fluorescence is observed. The exam will help identify the location of the lymphatic vessels and nodes in the areas fluoresced.
Receives: Drug: Indocyanine Green; Device: MultiSpectral Imaging System
Clearance arm - Healthy individualsExperimentalSubjects in the clearance arm will have an initial study visit that involves injections of 0.1 mg/ml of Indocyanine Green (ICG) intradermally into the web spaces of the hands in both upper extremities. Multispectral video and still images will be recorded using the MultiSpectral Imaging System (MSImager). Follow up imaging sessions will occur weekly for three weeks for a minimum of four study visits total.
Receives: Drug: Indocyanine Green

What is being measured

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

  1. Contraction Rate

    The contraction rate is measured as lymphatic vessel contractions/min in the dominant lymphatic vessel efferent to the injection site using the MultiSpectral Imaging System (MSImager) that captures real time movies. The MSImager software analyses the signal intensity to determine the contraction rate.

    Measured: 36 months

Secondary outcomes (1)
  1. Lymphatic Pressure

    The lymphatic pressure is measured using a transparent cuff and the Multispectral Imaging System to determine indirect lymphatic pressure and recorded as mm Hg.

    Measured: 36 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Indocyanine Green and MultiSpectral Imaging System in people with Rheumatoid Arthritis, run by University of Rochester 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 5 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 Oct 2022. 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?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Contraction Rate (time frame: 36 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02680067, which also lists 1 linked publication.

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 Oct 2022.
