GBT Presents Data at 15th Annual Scientific Conference on Sickle Cell and Thalassemia – BioSpace

Real-world effectiveness data on Oxbryta (voxelotor) in the treatment of sickle cell disease featured as oral presentation

SOUTH SAN FRANCISCO, Calif., Oct. 26, 2020 (GLOBE NEWSWIRE) -- Global Blood Therapeutics, Inc. (GBT) (NASDAQ: GBT), today announced its participation in the 15th Annual Scientific Conference on Sickle Cell and Thalassemia (ASCAT)and 1stEHA European Sickle Cell Conference, taking place online on Oct. 26-31, 2020. Two abstracts have been accepted for presentation, including real-world effectiveness data of Oxbryta (voxelotor) tablets in the treatment of sickle cell disease (SCD).

GBT is focused on addressing sickle cell disease at its root cause to seek to modify the course of the disease, and, ultimately, mitigate the serious and life-threatening complications that often lead to long-term damage and early death, said Ted W. Love, M.D., president and CEO of GBT. Were pleased to be at ASCAT 2020, where we are sharing real-world effectiveness data demonstrating that the benefits of treatment of sickle cell patients with Oxbryta were consistent with the results of our Phase 3 HOPE Study.

The two abstracts presented at the conference provide greater insight into the safety and efficacy of Oxbryta:

Details of the ASCAT presentations are as follows:

As part of its presence at ASCAT, GBT will host an educational online symposium, Getting to the Root Cause: Understanding the Devastating Impact of SCD on Patients, on Monday, Oct. 26, 7-8 p.m. GMT. The symposium will include presentations by Caterina Minniti, M.D., professor of clinical medicine and pediatrics at Einstein College of Medicine and director of the Sickle Cell Center for Adults at Montefiore Medical Center; and Bart Biemond, M.D., Ph.D., professor of internal medicine and hematologist at the Faculty of Medicine of the University of Amsterdam. More information about the symposium, which is available to registered attendees of the ASCAT meeting, can be found in the conference program.

Coinciding with ASCAT, today GBT released a comprehensive report, Overview of the Sickle Cell Disease Environment in Select European Countries, in order to help raise awareness of SCD in Europe. The report is based on research conducted in five European countries and explores the burden of the disease on patients, families and health care systems. In addition, the report examines existing public policy efforts to address and alleviate the challenges faced by those living with SCD. SCD is one of the most prevalent genetic rare diseases in Europe, and despite a clinical understanding of SCD, estimated life expectancy for those affected by the disease is significantly lower than the European average, indicating an urgent need to improve the quality of care for these patients.

About Sickle Cell DiseaseSickle cell disease (SCD) affects an estimated 100,000 people in the United States,1 an estimated 52,000 people in Europe2 and millions of people throughout the world, particularly among those whose ancestors are from sub-Saharan Africa.1 It also affects people of Hispanic, South Asian, Southern European and Middle Eastern ancestry.1 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.3 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.3-5 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.4-7

About Oxbryta (voxelotor) TabletsOxbryta (voxelotor) is an oral, once-daily therapy for patients with sickle cell disease (SCD). Oxbryta works by increasing hemoglobins affinity for oxygen. Since oxygenated sickle hemoglobin does not polymerize, GBT believes Oxbryta blocks polymerization and the resultant sickling and destruction of red blood cells, which are primary pathologies faced by every single person living with SCD. With the potential to improve hemolytic anemia and oxygen delivery, 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.

GBT plans to seek regulatory approvals to expand the potential use of Oxbryta in the United States for the treatment of SCD in children age 4 to 11 years and to treat hemolytic anemia in SCD in people age 12 years and older in Europe.

Important Safety InformationOxbryta 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).
