FDA Grants Orphan Drug Tag to AGIO's Tebapivat for Rare Cancer

Read MoreHide Full Article

Agios Pharmaceuticals, Inc. (AGIO - Free Report) announced that the FDA has granted orphan drug designation to its novel pyruvate kinase (PK) activator, tebapivat, for the treatment of myelodysplastic syndromes (MDS), a rare type of blood cancer.

The FDA generally grants orphan drug designation to investigational therapies that address rare medical diseases or conditions affecting fewer than 200,000 people in the United States. The perquisites that come from this designation include assistance in the drug development process, tax credits for clinical costs, exemptions from certain FDA fees and seven years of marketing exclusivity upon potential approval.

Agios is developing tebapivat (formerly, AG-946), its PK activator candidate, as a potential treatment for MDS and hemolytic anemias.

The company is currently starting a phase IIb study on tebapivat for treating lower-risk MDS. It has already achieved clinical proof-of-concept in a phase IIa study on tebapivat as a potential treatment for anemia in lower-risk MDS.

Shares of Agios have skyrocketed 98.9% so far this year compared with the industry’s rise of 14.2%.

AGIO’s Lead PK Activator Mitapivat Holds Promise

Agios’ lead PK activator, Pyrukynd (mitapivat), was approved for treating hemolytic anemia in adults with PK deficiency in the United States and the EU in 2022.

Pyrukynd is the first disease-modifying therapy approved to treat adults with PK deficiency, a rare and debilitating blood disorder.

Agios is also conducting two phase III studies, namely ACTIVATE-kids and ACTIVATE-kidsT, on Pyrukynd for PK deficiency in pediatric patients who are not regularly transfused and are regularly transfused, respectively.

Apart from PK deficiency, Pyrukynd is also being developed for other hemolytic anemias, including sickle cell disease (SCD) and thalassemia, in several label expansion studies.

Based on the encouraging progress in clinical development across both indications, Agios expects to launch Pyrukynd in thalassemia commercially by 2025 and SCD by 2026.

The FDA has already granted orphan drug designations to mitapivat for both thalassemia and SCD.
