CAMBRIDGE, Mass.--(BUSINESS WIRE)--Jul. 10, 2019--
Akebia Therapeutics, Inc. (Nasdaq: AKBA), today announced that its collaboration partner, Japan Tobacco, Inc. (JT) and its subsidiary Torii Pharmaceutical Co., Ltd. (Torii), reported positive top-line results from a pivotal Phase 3 comparative study evaluating Riona® Tablets 250mg (generic name in Japan: ferric citrate hydrate) for the treatment of iron deficiency anemia (IDA) in adult patients in Japan. JT and Torii hold the exclusive rights to develop and commercialize Riona in Japan. Upon successful completion of its Phase 3 program, JT and Torii stated that they expect to file an application for approval of IDA as an additional indication for Riona in Japan.
Riona was approved in Japan in 2014 as an oral treatment for the improvement of hyperphosphatemia in patients with chronic kidney disease (CKD), including dialysis-dependent and non-dialysis dependent CKD. Ferric citrate is approved and marketed in the United States by Akebia under the trade name Auryxia® (ferric citrate) for the control of serum phosphorus levels in adult patients with CKD on dialysis and for the treatment of IDA in adult patients with CKD not on dialysis.
“We congratulate JT and Torii on this important step toward expanding Riona’s indication and look forward to their progress to bring Riona to adult patients for the treatment of IDA in Japan,” stated John P. Butler, President and Chief Executive Officer of Akebia.
About JT and Torii’s Phase 3 Study in Iron Deficiency Anemia
JT and Torii’s public announcement highlighted that their study used a double blind, randomized and parallel-group design to evaluate the efficacy and safety of oral Riona in comparison to oral sodium ferrous citrate over seven weeks in adult patients with IDA. The companies have previously disclosed a target sample size of 480 patients. According to their announcement, “The top-line results show that the study met the primary endpoint by establishing non-inferiority of Riona compared with a control drug in the changes in hemoglobin level from baseline at week 7. Riona showed a favorable tolerability profile on safety within the treatment period. Regarding the safety endpoint, the incidence rates of nausea / vomiting (adverse events) were 13.0% / 3.2% (Riona) and 32.7% / 15.2% (control drug), respectively.”

IMPORTANT U.S. SAFETY INFORMATION FOR AURYXIA® (ferric citrate)
AURYXIA® (ferric citrate) is contraindicated in patients with iron overload syndromes, e.g., hemochromatosis.
WARNINGS AND PRECAUTIONS
- Iron Overload: Increases in serum ferritin and transferrin saturation (TSAT) were observed in clinical trials with AURYXIA in patients with chronic kidney disease (CKD) on dialysis treated for hyperphosphatemia, which may lead to excessive elevations in iron stores. Assess iron parameters prior to initiating AURYXIA and monitor while on therapy. Patients receiving concomitant intravenous (IV) iron may require a reduction in dose or discontinuation of IV iron therapy.
- Risk of Overdosage in Children Due to Accidental Ingestion: Accidental ingestion and resulting overdose of iron-containing products is a leading cause of fatal poisoning in children under 6 years of age. Advise patients of the risks to children and to keep AURYXIA out of the reach of children.
Most common adverse reactions with AURYXIA were:
- Hyperphosphatemia in CKD on Dialysis: Diarrhea (21%), discolored feces (19%), nausea (11%), constipation (8%), vomiting (7%) and cough (6%).
- Iron Deficiency Anemia in CKD Not on Dialysis: Discolored feces (22%), diarrhea (21%), constipation (18%), nausea (10%), abdominal pain (5%) and hyperkalemia (5%).
- Pregnancy and Lactation: There are no available data on AURYXIA use in pregnant women to inform a drug-associated risk of major birth defects and miscarriage. However, an overdose of iron in pregnant women may carry a risk for spontaneous abortion, gestational diabetes and fetal malformation. Data from rat studies have shown the transfer of iron into milk, hence, there is a possibility of infant exposure when AURYXIA is administered to a nursing woman.
