EC grants drug orphan designation for SCD

The European Commission (EC) has designated GBT440 as an orphan medicinal product for the treatment of sickle cell disease (SCD).

GBT440 is being developed as a potentially disease-modifying therapy for SCD. The drug works by increasing hemoglobin’s affinity for oxygen.

Since oxygenated sickle hemoglobin does not polymerize, it is believed that GBT440 blocks polymerization and the resultant sickling of red blood cells.

If GBT440 can restore normal hemoglobin function and improve oxygen delivery, the drug may be capable of modifying the progression of SCD.

Preclinical research published in the British Journal of Haematology earlier this year suggests that GBT440 is disease-modifying.

Early results from an ongoing phase 1/2 study of GBT440, which were presented at the 2015 ASH Annual Meeting, appeared promising as well.

Results from that study suggest that GBT440 can increase hemoglobin levels while decreasing reticulocyte counts, erythropoietin levels, and sickle cell counts.

Researchers also found the drug to be well tolerated, with no serious adverse events attributed to GBT440.

“Receiving orphan designation from the EC marks a significant milestone both for the SCD community and for GBT [Global Blood Therapeutics Inc.],” said Ted W. Love, MD, president and chief executive officer of Global Blood Therapeutics Inc., the company developing GBT440.

“SCD is a devastatingly severe disease with limited treatment options, and this designation, together with our fast track and orphan drug designations by the United States Food and Drug Administration, reflect the recognition of the broader regulatory community of this urgent unmet medical need.”

The EC grants orphan designation to therapies intended to treat life-threatening or chronically debilitating conditions affecting no more than 5 in 10,000 people in the European Union, and where no satisfactory treatment is available.

Orphan designation provides the company developing a drug with regulatory and financial incentives, including protocol assistance, 10 years of market exclusivity once the drug is approved, and reductions in, or exemptions from, fees.
