PYRUKYND® (mitapivat) Approved in the EU for the Treatment of Pyruvate Kinase (PK) Deficiency in Adult Patients
“People with PK deficiency suffer from a lifetime of chronic anemia, associated complications and symptoms that can be detrimental to their work, family and social lives,” said Andreas Glenthøj, hematologist and head of the
“With today’s EU approval, we are proud to expand the positive impact of PYRUKYND® for more patients with PK deficiency around the globe,” said
Agios is providing access to PYRUKYND® for the treatment of PK deficiency in adults receiving care in the EU through a global managed access program. More details about this program can be found on Agios.com.
PYRUKYND® was previously granted orphan drug designation by the EMA, which is maintained at the time of EU marketing authorization. Agios has also applied for a marketing authorization for PYRUKYND® as a treatment for PK deficiency in adult patients in

PYRUKYND® Safety and Efficacy Data
- The Phase 3 ACTIVATE trial of mitapivat achieved its primary endpoint. PYRUKYND® demonstrated a statistically significant increase in hemoglobin in patients with PK deficiency who are not regularly transfused.
- 40 percent (n=16) of patients randomized to PYRUKYND® achieved a hemoglobin response, compared to 0 patients randomized to placebo (2-sided p<0.0001).
- Statistically significant improvements compared to placebo were also demonstrated for all pre-specified secondary endpoints, including markers of hemolysis and ineffective erythropoiesis.
- The Phase 3 ACTIVATE-T trial of mitapivat achieved its primary endpoint. Mitapivat demonstrated a statistically significant and clinically meaningful reduction in transfusion burden for patients who are regularly transfused.
- 37 percent (n=10) of patients achieved a transfusion reduction response, defined as a ≥33% reduction in transfusion burden in the 24-week fixed dose period compared with individual historical transfusion burden standardized to 24 weeks.
- 22 percent (n=6) of patients were transfusion-free during the fixed-dose period.
- The most common adverse reaction across both studies was insomnia (19.4%), and the most common laboratory abnormalities observed were oestrone decreased (males) (43.5%) and oestradiol decreased (males) (8.7%).

The company is enrolling pediatric PK deficiency patients in two pivotal studies – ACTIVATE-kids and ACTIVATE-kidsT – in patients who are not regularly transfused and who are regularly transfused, respectively. Agios also continues to advance its Phase 3 ENERGIZE and ENERGIZE-T studies in non-transfusion-dependent and transfusion-dependent adults with thalassemia, respectively, as well as its Phase 2/3 RISE UP study in sickle cell disease.
About PK Deficiency
Pyruvate kinase (PK) deficiency is a rare, inherited disease that presents as chronic hemolytic anemia, which is the accelerated destruction of red blood cells. The inherited mutation in the PKLR gene can cause a deficit in energy within the red blood cell, as evidenced by lower PK enzyme activity, a decline in adenosine triphosphate (ATP) levels and a build-up of upstream metabolites, including 2,3-DPG (2,3-diphosphoglycerate).
PK deficiency is associated with serious complications, including gallstones, pulmonary hypertension, extramedullary hematopoiesis, osteoporosis and iron overload and its sequelae, which can occur regardless of the degree of anemia or transfusion burden. PK deficiency can also cause quality of life problems, including challenges with work and school activities, social life and emotional health. Current management strategies for PK deficiency, including red blood cell transfusions and splenectomy, are associated with both short- and long-term risks.

IMPORTANT SAFETY INFORMATION
Acute Hemolysis: Acute hemolysis with subsequent anemia has been observed following abrupt interruption or discontinuation of PYRUKYND in a dose-ranging study. Avoid abruptly discontinuing PYRUKYND. Gradually taper the dose of PYRUKYND to discontinue treatment if possible. When discontinuing treatment, monitor patients for signs of acute hemolysis and anemia including jaundice, scleral icterus, dark urine, dizziness, confusion, fatigue, or shortness of breath.
Adverse Reactions: Serious adverse reactions occurred in 10% of patients receiving PYRUKYND in the ACTIVATE trial, including atrial fibrillation, gastroenteritis, rib fracture, and musculoskeletal pain, each of which occurred in 1 patient. In the ACTIVATE trial, the most common adverse reactions including laboratory abnormalities (≥10%) in patients with PK deficiency were estrone decreased (males), increased urate, back pain, estradiol decreased (males), and arthralgia.
- Strong CYP3A Inhibitors and Inducers: Avoid concomitant use.
- Moderate CYP3A Inhibitors: Do not titrate PYRUKYND beyond 20 mg twice daily.
- Moderate CYP3A Inducers: Consider alternatives that are not moderate inducers. If there are no alternatives, adjust PYRUKYND dosage.
- Sensitive CYP3A, CYP2B6, CYP2C Substrates Including Hormonal Contraceptives: Avoid concomitant use with substrates that have narrow therapeutic index.
- UGT1A1 Substrates: Avoid concomitant use with substrates that have narrow therapeutic index.
- P-gp Substrates: Avoid concomitant use with substrates that have narrow therapeutic index.
Hepatic Impairment: Avoid use of PYRUKYND in patients with moderate and severe hepatic impairment.
