About this study

Official title: Determination of the in Vivo Recovery and Survival of EryDex (Dexamethasone Sodium Phosphate Encapsulated in Autologous Erythrocytes) in Non-patient Volunteers

This is a randomized, single-blind, single-center, concurrently controlled, exploratory, Phase I study to determine the in vivo kinetics (24-hour post-infusion recovery and T50 survival) of EryDex System (EDS) -processed autologous red blood cells (RBC) in non-patient volunteers. A total of 12 non-patient volunteer subjects will be enrolled and assigned to one of the 2 groups (6 subjects in active arm group, 6 subjects in sham arm group).

Read the detailed description

EryDex System (EDS) is a combination product used to administer dexamethasone sodium phosphate (DSP) by ex vivo encapsulation in autologous erythrocytes which are re-infused. DSP is dephosphorylated in RBCs to release dexamethasone.

The 12 subjects who meet all of the inclusion/exclusion criteria will be assigned to one of the 2 groups, consisting of 6 subjects each, as follows:

  • Group 1 (active drug arm): 15-20 mg DSP loaded in RBC using the EDS.
  • Group 2 (sham arm): sham treated autologous RBC using the EDS

One 50±5mL aliquot of blood collected from each subject will be treated using the EDS process (either active drug or sham) and the resultant processed RBCs will be radiolabeled with Chromium-51 (51Cr) for the in vivo kinetic study. A second 10±5mL simultaneously collected sample will be labeled with Technetium-99m (99mTc) to estimate the subject's blood volume. These labeled aliquots will be mixed, and simultaneously infused through a peripheral vein via butterfly or similar catheter (total dose 20-40 μCi). Blood samples will be collected from the subject's contralateral arm immediately pre-infusion and at 5, 7.5, 10, 12.5, 15, 20, and 30 minutes (± 3 min), and on Day 1, 24 hours (±2 h) after completion of infusion. Vital signs will be assessed after the 30-min sample on Day 0 and again on Day 1 before the 24-h sample is collected. Additional blood samples will be collected at 48 (±4 h) and 72 (±4 h) hours and 7 (±1 d) days post-infusion, and then weekly through 49 days post-infusion, with a window of ±2 days for each visit.

What participants receive

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

  • DSP loaded RBC using EryDex SystemDrug

    Also called EryDex System

    Intravenous infusion of 10 mg DSP encapsulated in autologous erythrocytes. Peripheral blood samples are taken over 49 days to determine the 24-hour recovery and survival (T50) of the infused RBC.

  • Sham treated RBC using the EryDex SystemDrug

    Also called EryDex System

    Intravenous infusion of sham treated autologous erythrocytes. Peripheral blood samples are taken over 49 days to determine the 24-hour recovery and survival (T50) of the infused RBC.

What is being measured

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

  1. 24-hour post transfusion recovery of infused autologous RBCs

    The 24-hour recovery of autologous RBCs loaded with DSP or sham using the EDS will be greater than 75% with 95% confidence. For RBC kinetics and recovery will be reported as mean, 2-sided 95% CI on the mean, standard deviation, minimum and maximum.

    Measured: 24 hours

  2. Long-term survival of infused autologous RBCs assessed with T50 (Time to disappearance of 50% of the labelled red blood cells from the circulation)

    For RBC T50 will be reported as mean, 2-sided 95% CI on the mean, standard deviation, minimum and maximum.

    Measured: up to 49 days

Secondary outcomes (1)
  1. Special laboratory tests

    pH at 37°C, hemolysis, ATP, 2,3-DPG, extracellular potassium, extracellular glucose, extracellular lactate, packed cell volume, RBC morphology and RBC indices. In particular free haemoglobin and and hematuria will be assessed on all defined time points.The measure is a composite outcome

    Measured: up to 49 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing DSP loaded RBC using EryDex System in people with Healthy, run by Quince Therapeutics S.p.A. 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 7 inclusion and 30 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 1 Feb 2016. 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. 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?

24-hour post transfusion recovery of infused autologous RBCs (time frame: 24 hours). 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 1 Feb 2016.
