CAMBRIDGE, Mass.--(BUSINESS WIRE)--Akebia Therapeutics, Inc. (Nasdaq: AKBA), today announced that its wholly-owned subsidiary, Keryx Biopharmaceuticals, Inc., and its licensor Panion & BF Biotech, Inc., have entered into a Settlement and License Agreement (Agreement) with Par Pharmaceutical, Inc., an Endo International company (Par).

Additionally, in accordance with the Agreement, the parties will terminate all ongoing Hatch-Waxman litigation between Keryx and Panion and Par regarding Auryxia patents pending in the U.S. District Court for the District of Delaware and the U.S. District Court for the Southern District of New York.
The Agreement is confidential and subject to review by the U.S. Federal Trade Commission and the U.S. Department of Justice.

IMPORTANT U.S. SAFETY INFORMATION FOR AURYXIA® (ferric citrate) CONTRAINDICATION
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.
ADVERSE REACTIONS
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%).
SPECIFIC POPULATIONS
- 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.
