(Nasdaq: AFFY) and Takeda Pharmaceutical Company Limited (Takeda) today have decided to voluntarily recall all lots of OMONTYS® (peginesatide) Injection to the user level as a result of new postmarketing reports regarding serious hypersensitivity reactions, including anaphylaxis, which can be life-threatening or fatal. The companies have been working actively with the U.S. Food and Drug Administration (FDA) which has indicated its agreement with this decision. The companies have also issued a letter to health care professionals indicating that no new or existing patients should receive OMONTYS.
To date, fatal reactions have been reported in approximately 0.02% of patients following the first dose of intravenous administration. The reported serious hypersensitivity reactions have occurred within 30 minutes after such administration of OMONTYS. There have been no reports of such reactions following subsequent dosing, or in patients who have completed their dialysis session. Since launch, more than 25,000 patients have received OMONTYS in the postmarketing setting. The rate of overall hypersensitivity reactions reported is approximately 0.2% with approximately a third of these being serious in nature including anaphylaxis requiring prompt medical intervention and in some cases hospitalization. The companies are actively investigating these cases. In the meantime, dialysis organizations are instructed to discontinue use. Customers will be provided instructions on how to return the product to the manufacturer for a refund. For customers with questions, please call 1-855-466-6689 [9:00 a.m. to 5:00 p.m. Eastern Standard Time, Monday through Friday].

IMPORTANT SAFETY INFORMATION
WARNING: ESAs INCREASE THE RISK OF DEATH, MYOCARDIAL INFARCTION, STROKE, VENOUS THROMBOEMBOLISM, THROMBOSIS OF VASCULAR ACCESS AND TUMOR PROGRESSION OR RECURRENCE.
Chronic Kidney Disease:
OMONTYS is contraindicated in patients with uncontrolled hypertension and in patients who have had serious allergic reactions, which may include anaphylaxis, to OMONTYS.
Warnings and Precautions
Increased mortality, myocardial infarction, stroke, and thromboembolism:
Hypertension (see Contraindications): Appropriately control hypertension prior to initiation of and during treatment with OMONTYS. Reduce or withhold OMONTYS if blood pressure becomes difficult to control.
Serious allergic reactions (see Contraindications): Serious allergic reactions, including anaphylactic reactions, hypotension, bronchospasm, angioedema and generalized pruritus, may occur in patients treated with OMONTYS. Immediately and permanently discontinue OMONTYS and administer appropriate therapy if a serious allergic reaction occurs.
Lack or loss of response to OMONTYS: Initiate a search for causative factors. If typical causes of lack or loss of hemoglobin response are excluded, evaluate for antibodies to peginesatide.
Dialysis management: Patients receiving OMONTYS may require adjustments to dialysis prescriptions and/or increased anticoagulation with heparin to prevent clotting of the extracorporeal circuit during hemodialysis.
Laboratory monitoring: Evaluate transferrin saturation and serum ferritin prior to and during OMONTYS treatment. Administer supplemental iron therapy when serum ferritin is less than 100mcg/L or when serum transferrin saturation is less than 20%. Monitor hemoglobin every 2 weeks until stable and the need for RBC transfusions is minimized. Then, monitor monthly.
Most common adverse reactions in clinical studies in patients with CKD on dialysis treated with OMONTYS were dyspnea, diarrhea, nausea, cough, and arteriovenous fistula site complication.
