Purpose: Sucroferric oxyhydroxide is the newest phosphate binder to receive US Food and Drug Administration approval for patients on dialysis. The purpose of this review is to critically evaluate the studies that have been conducted with this medication and determine where it may fit in the clinician's overall treatment plan for hyperphosphatemia in patients with chronic kidney disease.
Methods: Literature searches were performed in the PubMed database and www.ClinicalTrials.gov using the search terms sucroferric oxyhydroxide, and PA21 phosphate binder. Limits were set to include only clinical trials performed in human subjects.
Findings: Four completed clinical trials and 3 ongoing studies were identified. Completed clinical trials included Phase I, Phase II, and Phase III studies that all demonstrated the ability of sucroferric oxyhydroxide to lower serum phosphorus concentrations. One study compared sucroferric oxyhydroxide with sevelamer and reported no statistically significant difference in serum phosphorus-lowering ability. The ongoing trials are evaluating sucroferric oxyhydroxide for long term use, in peritoneal dialysis patients, and compared with calcium-based phosphate binders.
Implications: Sucroferric oxyhydroxide is an effective phosphate binder for chronic kidney disease patients receiving hemodialysis and may offer an advantage in terms of pill burden. Gastrointestinal side effects are similar to those of current phosphate binders. Advantages of other phosphate binders (ie, the lipid- and uric acid-lowering abilities of sevelamer) may outweigh the pill burden benefits of sucroferric oxyhydroxide.

In Vitro Study on Combined Effect of Drugs for Hyperphosphatemia on Phosphorus Adsorption Capacity.

Article Synopsis
- Phosphorus binders can be combined for better effects, but their performance might change due to pH levels or other medications.
- A study assessed how well different phosphorus binders work together, specifically looking at precipitated calcium carbonate (CC), ferric citrate hydrate (FC), lanthanum carbonate hydrate (LC), and sucroferric oxyhydroxide (SO).
- Results showed that SO maintained a strong adsorption capacity even when mixed with other binders, while combinations of CC + FC and FC + LC had decreased effectiveness due to citrate ions interfering with calcium and lanthanum ions.*

Article Synopsis
- Phosphate binders like sucroferric oxyhydroxide and sevelamer carbonate are used in kidney replacement therapy (KRT) to lower serum phosphorus levels, which are linked to health issues in chronic kidney disease.
- This study compared the effectiveness and safety of these two drugs through a meta-analysis of five randomized trials, finding no significant difference in reducing serum phosphorus between them.
- However, sucroferric oxyhydroxide had a better gastrointestinal side effect profile, making it a preferable option for patients in KRT.

Article Synopsis
- - The text discusses a case involving a 51-year-old male with end-stage kidney disease who experienced issues during a colonoscopy due to the effects of the iron-based medication sucroferric oxyhydroxide, which is used to manage high phosphate levels in patients on dialysis.
- - During a flexible sigmoidoscopy, the medication caused the bowel to be obscured by "charcoal-like" material, making it difficult for doctors to see and evaluate the patient's condition, leading to the decision to halt the medication for two weeks before a repeat procedure.
- - After stopping the medication, the patient's repeat sigmoidoscopy was successful in providing clear visualization, ultimately revealing a benign lipoma, highlighting the importance of considering medication effects on

Article Synopsis
- This study explores the use of sucroferric oxyhydroxide (SO) for managing high serum phosphorus levels in patients with end-stage kidney disease (ESKD) undergoing peritoneal dialysis (PD).* -
- An analysis of 402 patients showed significant improvements, with the proportion of patients achieving optimal phosphorus levels rising from 32.1% at the start to between 46.5% and 54% over the year, alongside a reduction in the number of phosphate binder pills taken daily.* -
- Overall, SO treatment effectively lowered serum phosphorus levels and decreased pill burden regardless of kidney function changes, suggesting it can be a beneficial option for managing hyperphosphatemia in ESKD patients on PD
