Hemin in Healthy Subjects
A Phase 1 study testing Hemin infusion in people with Healthy Volunteers, run by Mayo Clinic at 1 site in United States.
Trial summary
This study is being done because we want to learn if hemin can increase the production of heme oxygenase 1. Heme oxygenase 1 (HO-1) is an enzyme which protects cells from physical, chemical, and biologic stress. Read more about this study

About this study
Official title: Effect of Hemin on Heme-Oxygenase-1 Activity in Healthy Subjects
This study is being done because we want to learn if hemin can increase the production of heme oxygenase 1. Heme oxygenase 1 (HO-1) is an enzyme which protects cells from physical, chemical, and biologic stress. Hemin is produced from red blood cells and is approved by the Food and Drug Administration for treating acute porphyria, which is an inherited condition caused by an enzyme deficiency.
Read the detailed description
Heme-oxygenase 1 (HO-1) degrades heme, protects cells against oxidative stress, and is beneficial in several experimental models but has not been pharmacologically activated in humans. The objectives of this study were to evaluate the effects of hemin on HO-1 activity in healthy subjects. Hemin is the most powerful inducer of HO-1. Hemin is FDA-approved to treat acute intermittent porphyria. In addition, hemin has also been used to treat thalassemia intermedia, myelodysplastic syndrome, and to control liver allograft failure due to recurrence of erythropoietic prototheria. Our hypothesis is that compared to placebo, hemin will increase HO-1 in humans. Ten healthy subjects will be randomized to hemin (n = 5, Panhematin®, Ovation Pharmaceuticals, 3 mg/kg i.v. in 25% albumin) or placebo (n = 5, 25% albumin) infusion. HO-1 activity will be assessed before and after (4, 6, 24, and 48 hours) infusions.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Hemin infusionDrug
Hemin (Panhematin®, Ovation Pharmaceuticals, Deerfield, IL) will be administered through a large-caliber peripheral vein at a dose of 1.25 mL/kg and at a rate of 60 mL/hour. To enhance stability, Panhematin® will be diluted in ~ 132 mL of 25% albumin to obtain a hemin concentration of 2.4 mg/mL.
placebo infusionDrug
25 % albumin will be administered through a large-caliber peripheral vein at a dose at a rate of 60 mL/hour.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Hemin infusion in people with Healthy Volunteers, run by Mayo Clinic 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?
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 Apr 2009. 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?
Venous carboxyhemoglobin concentrations (time frame: at 6 hours). The study lists 3 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 Apr 2009.
