Label indication LANTHANUM CARBONATE is a phosphate binder indicated to reduce serum phosphate in patients with end-stage renal disease (ESRD). Management of elevated serum phosphorus levels in patients with ESRD usually includes all of the following: reduction in dietary intake of phosphate, removal of phosphate by dialysis, and reduction of intestinal phosphate absorption with phosphate binders.

Percentage of Participants Achieving Age-Specific Kidney Disease Outcomes Quality Initiative (KDOQI) Targets for Serum Phosphate Level Following 8 Weeks of Lanthanum Carbonate Administration (Part 2 + Part 3)
After 8 weeks of lanthanum carbonate administration in Part 2 and/or in Part 3

KDOQI serum phosphorus targets were defined for: Adolescents aged greater than or equal to (\>=) 12 to less than (\<) 18 years to be less than or equal to (\<=) 5.5 milligrams per deciliter (mg/dL) (1.78 millimoles per liter \[mmol/L\]); Children aged \>=10 years to \<12 years to be \<= 6.0 mg/dL (1.94 mmol/L). Percentage of participants achieving age-specific KDOQI targets for serum phosphate level was reported only for the participants who had received lanthanum carbonate during part 2 or part 3. Data was analyzed and presented as per the intervention received in this study related to this outcome and not analyzed based on each part of the study.

Natural Logarithm Transformed Serum Intact Fibroblast Growth Factor (FGF-23) Levels at Week 12 Last Observation Carried Forward (LOCF)
12 Weeks

FGF-23 plays an important role in mineral metabolism in chronic kidney disease patients. It is secreted by bone cells in response to hyperphosphatemia. It acts to decrease renal phosphate reabsorption. Administration of a phosphate-binder (i.e. lanthanum carbonate) was expected to produce a reduction in FGF-23 levels.

Serum phosphorus levels at 8 weeks.

Net Phosphorous Absorption
10 hours post-dose

Net phosphorous absorption (Lanthanum carbonate period) = phosphorous ingested in meal minus (Rectal effluent phosphorous after Lanthanum carbonate + meal minus Rectal effluent phosphorous after fasting). Net phosphorous absorption (Sevelamer Carbonate period) = Phosphorous ingested in meal minus (Rectal effluent phosphorous after Sevelamer carbonate + meal minus Rectal effluent phosphorous after fasting). Net phosphorous absorption (Meal only period) = Phosphorous ingested in meal minus (Rectal effluent phosphorous after meal only minus Rectal effluent phosphorous after fasting).

Frequently asked questions about Fosrenol

What is Fosrenol used for?

Fosrenol is used in patients with Stage 5 chronic kidney disease. It is a small molecule therapy developed by Takeda Pharmaceutical Company Limited in the nephrology therapeutic area. Its clinical development has focused on this advanced kidney disease population.

Who makes Fosrenol?

Fosrenol is developed by Takeda Pharmaceutical Company Limited, which trades under the ticker TAK. Takeda is the company responsible for the drug's clinical program in Stage 5 chronic kidney disease.

What phase is Fosrenol in?

Fosrenol has been studied in Phase 3 clinical development. Its Phase 3 trial in Stage 5 chronic kidney disease is completed, and no trials for Fosrenol are currently listed as active.

What clinical trials is Fosrenol in?

Fosrenol has been evaluated in the Phase 3 trial NCT00441545, titled Head to Head Study Against Sevelamer Hydrochloride. That trial enrolled 182 participants with Stage 5 chronic kidney disease across the United States, Germany, Puerto Rico, and the United Kingdom, and it is completed.

Is Fosrenol the same as lanthanum carbonate?

Yes, Fosrenol is also known as lanthanum carbonate. Fosrenol (Lanthanum Carbonate) refers to the same small molecule therapy developed by Takeda Pharmaceutical Company Limited for Stage 5 chronic kidney disease.

How was the Fosrenol Phase 3 trial designed?

The Phase 3 trial NCT00441545 was a randomized, active-controlled study comparing Fosrenol against sevelamer hydrochloride. It enrolled 182 participants aged 18 years and older with Stage 5 chronic kidney disease, included both sexes, did not enroll healthy volunteers, and is completed.
