About this study

Official title: A Phase I Study to Determine the MTD and to Evaluate Pharmacokinetic, Safety/Tolerability, and Efficacy Profiles of IOP Injection for MRI Contrast Agent in Healthy Subjects

Study Objectives Primary: To determine MTD and dose limiting toxicities (DLTs) of IOP magnetic resonance imaging (MRI) contrast agent in healthy subjects.

Secondary:

  1. To characterize the pharmacokinetic profiles of IOP MRI contrast agent in healthy subjects.
  2. To evaluate safety/tolerability profiles of IOP MRI contrast agent in healthy subjects.
  3. To explore efficacy profiles of IOP MRI contrast agent for liver organ in healthy subjects.
Read the detailed description

Iron Oxide Nano Particle m-PEG-silane (IOP) Injection belongs to Superparamagnetic iron oxide (SPIO) can shorten the T2 relaxation time very effectively and reduces signal intensity in normal tissues. The mechanism of action increases after the particles have been phagocytosed by cells of the RES. Tissues with decreased RES function (e.g., metastases, primary liver cancer, cysts and various benign tumors, adenomas, and hyperplasia) retain their native signal intensity. In this study, investigators will characterize the PK profile, iron metabolism and preliminary efficacy of IOP Injection.

What is being measured

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

  1. Dose limiting toxicities (DLTs) of IOP

    DLT is defined as any grade 2 or above toxicity by NCI-CTCAE version 4.03, as determined by the investigator and sponsor, to be at least possibly related in causality to the administered investigational product IOP

    Measured: Up to 14 days post-IOP injection

  2. Maximum tolerated dose (MTD) of IOP

    MTD is defined as the prior dose level below the dose level at which 2/6 subjects suffer dose limiting toxicities

    Measured: Up to 14 days post-IOP injection

Secondary outcomes (6)
  1. Pharmacokinetic parameters-Cmax

    Cmax: the observed maximum drug concentration in plasma after dosing

    Measured: Up to 3 days post-IOP injection

  2. Pharmacokinetic parameters-Tmax

    Tmax: the time at which Cmax was reached

    Measured: Up to 3 days post-IOP injection

  3. Pharmacokinetic parameters-AUC0-t

    the truncated area under the plasma concentration-time curve from the beginning of dosing to time t

    Measured: Up to 3 days post-IOP injection

  4. Pharmacokinetic parameters-AUC0-inf

    the area under the plasma concentration-time curve from the beginning of dosing to time t (AUC0-t) extrapolated to time infinity

    Measured: Up to 3 days post-IOP injection

  5. Pharmacokinetic parameters-T1/2

    terminal elimination half-life

    Measured: Up to 3 days post-IOP injection

  6. Changes in laboratory safety tests (hematology, biochemistry, urinalysis, bleeding time) from baseline

    Measured: Up to 14 days post-IOP injection

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing IOP Injection and 0.9% normal saline in people with Magnetic Resonance Imaging, run by MegaPro Biomedical Co. Ltd. at 1 site in Taiwan.

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 21 inclusion and 13 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 17 Aug 2018. 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 Taiwan. 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. Some participants in this study may receive a placebo. 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?

Dose limiting toxicities (DLTs) of IOP (time frame: Up to 14 days post-IOP injection). The study lists 2 primary outcomes in all. 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 17 Aug 2018.
