I.V. Triferic Data to Support Upcoming New Drug Application
Intraperitoneal Triferic Effectively Delivers Iron to Patients with Kidney Failure in Outpatient Setting
WIXOM, Mich., March 18, 2019 (GLOBE NEWSWIRE) -- Rockwell Medical, Inc. (NASDAQ: RMTI) (“Rockwell Medical” or the “Company”), a global biopharmaceutical company dedicated to improving outcomes for patients with end-stage renal disease (ESRD) and chronic kidney disease (CKD), today announced positive data from two studies evaluating intravenous (I.V.) and peritoneal dialysate (PD) formulations of Triferic® (ferric pyrophosphate citrate), the only therapy approved by the U.S. Food and Drug Administration (FDA) indicated to replace iron and maintain hemoglobin in adult hemodialysis (HD) patients with chronic kidney disease. The data from the studies will be presented at the Annual Dialysis Conference, the largest multi-disciplinary conference on dialysis, held March 16-19 in Dallas, Texas.
“We are encouraged by the data from this study, which demonstrates that I.V. Triferic delivers the same quantity of iron to patients as Triferic delivered via hemodialysate,” said Raymond D. Pratt, M.D., Chief Medical Officer of Rockwell Medical. “We believe Triferic has the potential to transform anemia management for all patients with hemodialysis-dependent chronic kidney disease. An I.V. formulation would give us the opportunity to integrate the use of Triferic at all dialysis centers— in the U.S. and abroad—regardless of the mode of bicarbonate delivery being used.”
I.V. Triferic for adult HD patients was developed pursuant to a Special Protocol Assessment (SPA), at which time the FDA confirmed that an equivalence approach to Triferic delivered via hemodialysate (Dialysate Triferic) would be acceptable for I.V. Triferic. The Company expects to submit a New Drug Application (NDA) for I.V. Triferic to the FDA during the second quarter of 2019, in which the study below will be submitted for FDA review.
I.V. Infusion of Triferic Delivers Same Quantity of Iron as Delivery via Hemodialysate
An open-label, randomized, multiple-period single dose study was conducted in 24 CKD-5HD patients to establish the equivalence of doses between dialysate and I.V. administration. Each patient received a baseline iron treatment and three randomized treatments of either Triferic 6.75 mg Fe I.V. pre-dialyzer; Triferic 6.75 mg Fe I.V. post-dialyzer; or Triferic 2 μM (110 μg Fe/L of hemodialysate). Serum and plasma iron were drawn at specified time points over 12 hours and analyzed for total iron (Fe) and Transferrin Bound Iron (TBI). Results from the study were as follows:
- Intravenous infusion of 6.5 mg iron as ferric pyrophosphate citrate (FPC) during three hours of hemodialysis delivers the same quantity of iron as when Triferic is delivered via hemodialysate;
- In Phase 3 clinical studies, Dialysate Triferic maintained iron status and hemoglobin concentrations;
- The amount of iron delivered in the pivotal clinical trials for Dialysate Triferic is now established as 6.5 mg Fe/treatment; and
- Administration of FPC into the pre-dialyzer blood line extends the ability to provide Triferic iron to all patients receiving hemodialysis or hemodiafiltration.
“Triferic administered via dialysate provides a safe and effective method to replace iron and maintain hemoglobin concentration in adults living with hemodialysis-dependent chronic kidney disease,” said Stuart Paul, President and Chief Executive Officer of Rockwell Medical. “Based upon results from our equivalency study, which demonstrate consistent results for I.V. Triferic, we plan to submit our data for review by the FDA as a part of our NDA. The NDA is expected to be submitted with the FDA during the second quarter of 2019. Additionally, the delivery of Triferic to peritoneal dialysis patients via the dialysate may improve patients’ ability to manage their anemia, typically in the home setting.”
Intraperitoneal Triferic May Serve as Effective and Simple Iron Replacement Option for Chronic Peritoneal Dialysis Patients
In a second study, 30 patients were enrolled in an open-label, randomized, two-period, single ascending dose study of Triferic administered in peritoneal dialysis fluid (PDF). Results demonstrated iron absorption from PDF was dose-dependent with peak serum iron profile (sFe) at approximately six hours with return to baseline over the next approximately eight hours. Clearance was similar to Triferic I.V. administration.
“The iron requirements in patients receiving peritoneal dialysis are less than hemodialysis patients; however, they still require supplemental iron to manage their anemia,” said Dr. Pratt. “This single-ascending dose study shows that Triferic can deliver iron to the systemic circulation when added to peritoneal dialysis fluid and may serve as an important means to managing anemia in an outpatient setting.”
Additional studies of Triferic in peritoneal dialysis patients will be required prior to submission of an NDA.
Triferic is the only FDA-approved therapy indicated to replace iron and maintain hemoglobin in hemodialysis patients via dialysate during each dialysis treatment, Triferic delivers approximately 5-7 mg iron with every hemodialysis treatment to the bone marrow and maintains hemoglobin without increasing irons stores (ferritin). Unlike IV iron products, Triferic binds iron immediately and completely to transferrin (carrier of iron in the body) upon entry into the blood and is then transported directly to the bone marrow to be incorporated into hemoglobin, with no increase in ferritin (stored iron and inflammation) and no anaphylaxis, addressing a significant medical need in overcoming Functional Iron Deficiency (FID) in ESRD patients.
