GBT Announces Upcoming Data Presentations at European Hematology Association (EHA) 2021 Virtual Congress
New Oxbryta® (voxelotor) Data from Phase 2a HOPE-KIDS 1 Study Demonstrate Improvement in Hemoglobin and Hemolysis in Children Ages 4 to 11 Years with Sickle Cell Disease
SOUTH SAN FRANCISCO, Calif., May 12, 2021 (GLOBE NEWSWIRE) -- Global Blood Therapeutics, Inc. (GBT) (NASDAQ: GBT) today announced that six abstracts related to its sickle cell disease (SCD) programs will be presented at the European Hematology Association (EHA) 2021 Virtual Congress, taking place online June 9-17, 2021. Results from an analysis of the Phase 2a HOPE-KIDS 1 Study (GBT440-007) in children with SCD ages 4 to 11 years treated with Oxbryta® (voxelotor) tablets will be presented for the first time in an oral session.
The HOPE-KIDS 1 analysis, which evaluated 45 children treated with Oxbryta (1,500 mg or weight-based equivalent), found that 47 percent achieved a hemoglobin increase of >1 g/dL at 24 weeks. Reductions in markers of hemolysis were also observed. Oxbryta was well tolerated, and no new adverse safety signals were detected. The most commonly reported treatment-related adverse events were diarrhea (11 percent), vomiting (11 percent) and rash (11 percent).
These findings from the HOPE-KIDS 1 Study are consistent with data from the Phase 3 HOPE Study of patients with SCD ages 12 years and older, which was published in The New England Journal of Medicine and presented as part of the Presidential Symposium at the EHA Congress in June 2019. The complete analysis of 72-week data from the HOPE Study was recently published in The Lancet Haematology, showing durable improvement in hemoglobin levels and reduction in hemolysis for patients receiving Oxbryta.
“New treatment options for younger children with sickle cell disease are urgently needed. We believe that reducing the sickling and destruction of red blood cells, thereby improving the anemia and hemolysis that characterize this devastating inherited condition early in life, could modify the course of the disease and alleviate serious and life-threatening complications,” said Ted W. Love, M.D., president and chief executive officer of GBT. “We are encouraged by the extensive body of new data being presented at this year’s EHA Congress, supporting the use of Oxbryta in both real-world and clinical trial settings. We look forward to potentially expanding access to Oxbryta over time across a broad range of sickle cell disease patients in the U.S., Europe, the Gulf Cooperation Council region and other areas.”
The European Medicines Agency (EMA) has accepted for review GBT’s Marketing Authorization Application (MAA) seeking full marketing authorization of Oxbryta in Europe to treat hemolytic anemia in SCD patients ages 12 years and older. GBT also plans to seek regulatory approval to expand the potential use of Oxbryta in the United States for the treatment of SCD in children as young as 4 years old.
The EHA abstracts are available at https://ehaweb.org. All oral and poster presentations will be available on the EHA website on Friday, June 11, at 9:00 a.m. CEST/3:00 a.m. EDT. Other abstracts to be presented include real-world evidence supporting the use of Oxbryta in patients ages 12 and older. Full details are as follows:

About Sickle Cell Disease
Sickle cell disease (SCD) affects an estimated 100,000 people in the United States,2 an estimated 52,000 people in Europe,3 and millions of people throughout the world, particularly among those whose ancestors are from sub-Saharan Africa.2 It also affects people of Hispanic, South Asian, Southern European and Middle Eastern ancestry.2 SCD is a lifelong inherited rare blood disorder that impacts hemoglobin, a protein carried by red blood cells that delivers oxygen to tissues and organs throughout the body.4 Due to a genetic mutation, individuals with SCD form abnormal hemoglobin known as sickle hemoglobin. Through a process called hemoglobin polymerization, red blood cells become sickled – deoxygenated, crescent-shaped and rigid.4-6 The sickling process causes hemolytic anemia (low hemoglobin due to red blood cell destruction) and blockages in capillaries and small blood vessels, which impede the flow of blood and oxygen throughout the body. The diminished oxygen delivery to tissues and organs can lead to life-threatening complications, including stroke and irreversible organ damage.5-8
About Oxbryta® (voxelotor) tablets
Oxbryta (voxelotor) is an oral, once-daily therapy for patients with sickle cell disease (SCD). Oxbryta works by increasing hemoglobin’s affinity for oxygen. Since oxygenated sickle hemoglobin does not polymerize, Oxbryta inhibits sickle hemoglobin polymerization and the resultant sickling and destruction of red blood cells, which are primary pathologies faced by every single person living with SCD. Through addressing hemolytic anemia and improving oxygen delivery throughout the body, GBT believes that Oxbryta has the potential to modify the course of SCD. On Nov. 25, 2019, Oxbryta received U.S. Food and Drug Administration (FDA) accelerated approval for the treatment of SCD in adults and children 12 years of age and older.8
As a condition of accelerated approval, GBT will continue to study Oxbryta in the HOPE-KIDS 2 Study, a post-approval confirmatory study using transcranial Doppler (TCD) flow velocity to assess the ability of the therapy to decrease stroke risk in children 2 to 15 years of age.
In recognition of the critical need for new SCD treatments, the FDA granted Oxbryta Breakthrough Therapy, Fast Track, Orphan Drug, and Rare Pediatric Disease designations for the treatment of patients with SCD. Additionally, Oxbryta has been granted Priority Medicines (PRIME) designation from the European Medicines Agency (EMA), and the European Commission (EC) has designated Oxbryta as an orphan medicinal product for the treatment of patients with SCD.
Important Safety Information
Oxbryta should not be taken if the patient has had an allergic reaction to voxelotor or any of the ingredients in Oxbryta. See the end of the patient leaflet for a list of the ingredients in Oxbryta. Oxbryta can cause serious side effects, including serious allergic reactions. Patients should tell their health care provider or get emergency medical help right away if they get rash, hives, shortness of breath or swelling of the face.
Patients receiving exchange transfusions should talk to their health care provider about possible difficulties with the interpretation of certain blood tests when taking Oxbryta.
The most common side effects of Oxbryta include headache, diarrhea, stomach (abdominal) pain, nausea, tiredness, rash and fever. These are not all the possible side effects of Oxbryta.
Before taking Oxbryta, patients should tell their health care provider about all medical conditions, including if they have liver problems; if they are pregnant or plan to become pregnant as it is not known if Oxbryta can harm an unborn baby; or if they are breastfeeding or plan to breastfeed as it is not known if Oxbryta can pass into breastmilk or if it can harm a baby. Patients should not breastfeed during treatment with Oxbryta and for at least two weeks after the last dose.
Patients should tell their health care provider about all the medicines they take, including prescription and over-the-counter medicines, vitamins and herbal supplements. Some medicines may affect how Oxbryta works. Oxbryta may also affect how other medicines work.
Patients are advised to call their doctor for medical advice about side effects. Side effects can be reported to the FDA at 1-800-FDA-1088. Side effects can also be reported to Global Blood Therapeutics at 1-833-428-4968 (1-833-GBT-4YOU).
