ferric pyrophosphate citrate
| Study group | Role | What they receive |
|---|---|---|
| Triferic via Hemodialysate | Experimental | Triferic will be mixed with the liquid bicarbonate concentrate used in the preparation of the hemodialysate solution. This will result in a final Triferic iron concentration in the dialysate of 2 µM (110 µg/L). The patients will receive Triferic over 4 hrs at one hemodialysis session. Receives: Drug: Triferic |
| Triferic via IV infusion( pre-dialyzer) | Experimental | Patients will receive a single 6.5-mg dose of Triferic iron administered IV over 3 hrs during hemodialysis via arterial blood line (pre-dialyzer) Receives: Drug: Triferic |
| Triferic via IV infusion (post-dialyzer) | Experimental | Patients will receive a single 6.5-mg dose of Triferic iron administered IV over 3 hrs during hemodialysis via venous blood line (post-dialyzer) Receives: Drug: Triferic |
What is being measured
The primary outcome is the main question the study is designed to answer.
Pharmacokinetics (PK) of Triferic Iron Administered Via Hemodialysate in Adult CKD-5HD Patients: Cmax.
The PK will be done by assessing the mean Cmax of total serum iron from Triferic administered via hemodialysate, compared to Triferic administered at a fixed IV dose of 6.6 mg iron/kg during a single dialysis session.
Measured: 1, 2, 3, 3.5, 4, 4.5, 5, 6, 8, 10, and 12 hours
Pharmacokinetics (PK) of Triferic Iron Administered IV in Adult CKD-5HD Patients:Cmax
Measured: 1, 2, 3, 3.5, 4, 4.5, 5, 6, 8, 10, and 12 hours
Pharmacokinetics (PK) of Triferic Iron Administered IV in Adult CKD-5HD Patients: AUC(0-end).
The PK will be done by assessing the mean AUC(0-end) of total serum iron from Triferic administered via hemodialysate, compared to Triferic administered at a fixed IV dose of 6.5 mg iron/kg during a single dialysis session.
Measured: 1, 2, 3, 3.5, 4, 4.5, 5, 6, 8, 10, and 12 hours
Secondary outcomes (1)
Safety Endpoint: Number of Participants With Treatment-emergent Serious Adverse Events (TESAEs) Incidence of Treatment Emergent Serious Adverse Events
Safety will be documented by recording the incidence of treatment-emergent serious adverse events (TESAEs).The number of patients that experienced treatment emergent serious adverse events will be quantified. Please see the adverse event table for specifics.
Measured: From the start of the HD #1 through the end of study participation or 7 days after the last dose of Triferic, whichever is later, assessed up to 2 months

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Triferic in people with End Stage Renal Disease, run by Rockwell Medical Technologies, Inc. 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 12 inclusion and 9 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 16 Nov 2020. 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 combined 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.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 16 Nov 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Pharmacokinetics (PK) of Triferic Iron Administered Via Hemodialysate in Adult CKD-5HD Patients: Cmax. (time frame: 1, 2, 3, 3.5, 4, 4.5, 5, 6, 8, 10, and 12 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 16 Nov 2020; AzTrials last refreshed its copy on 8 Nov 2026.
