Conference call today at 4:30 p.m. ET

SOUTH SAN FRANCISCO, Calif., Aug. 05, 2020 (GLOBE NEWSWIRE) -- Global Blood Therapeutics, Inc. (GBT) (NASDAQ: GBT) today reported recent business progress and financial results for the second quarter ended June 30, 2020.

“In the second quarter of 2020, we continued to make important progress on GBT’s vision of being a leading biopharmaceutical company and the leader in sickle cell disease. Despite the impact of COVID-19, we continued to successfully execute the launch of Oxbryta and make significant progress on new prescriptions, new prescribers, and payer coverage. During the quarter, we were pleased to see increased use of virtual engagements and telemedicine by healthcare professionals and continued growth of Oxbryta prescriptions. In addition, we made significant progress in our efforts to expand the approved use of Oxbryta for more patients in the United States and in Europe, with regulatory submissions planned by mid-2021,” said Ted W. Love, M.D., president and CEO of GBT.

“Last quarter was also marked by a magnification of health disparities driven by COVID-19, which is having an outsized impact on African Americans, and a renewed focus on racial injustice sparked by deaths due to police brutality. The sickle cell disease community lives and breathes these issues, and GBT is working to address them, as evidenced by our cohort of ACCEL grant recipients. We are committed to enacting real and lasting change for communities of color, especially when it comes to ensuring patients have access to the care they need and deserve,” added Dr. Love.

Recent Business Progress

Commercial

• Achieved Oxbryta^® (voxelotor) net sales of $31.5 million in the second quarter of 2020.
• Despite the impact of COVID-19, recorded approximately 1,000 new prescriptions of Oxbryta during the second quarter.
• The decrease in new prescriptions stabilized following an initial impact of COVID-19 at the end of the first quarter. The stabilization was primarily due to the increased use of telemedicine by healthcare providers and increased comfort with virtual engagements with GBT field teams. When the pandemic subsides, GBT expects that, over time, the number of new prescriptions will improve from current levels and surpass pre-COVID-19 levels.
• Conducted a review of patient charts, claims, and lab data that showed Oxbryta is being prescribed to a broad range of patients irrespective of hemoglobin (Hb) level, history of vaso-occlusive crisis (VOC), and current therapy for sickle cell disease (SCD). Almost half of patients started therapy with baseline Hb greater than 8 g/dL, and more than half take Oxbryta in combination with another SCD therapy.  
• Continued to secure Oxbryta reimbursement coverage, with 53% of lives covered by payers either through published policies or medical exceptions. GBT has secured fee-for-service Medicaid coverage in 42 states, including all 17 priority states where most SCD patients live. GBT believes it is on track to meet its goal of obtaining broad coverage by the end of the year.

Clinical

• Collaborated with clinical trial sites to implement appropriate protocols that would, over time, enable the resumption of patient enrollment and participation in GBT-sponsored clinical trials. The company believes it remains on track with the long-term timelines for its clinical trials.
• Presented four abstracts at the virtual edition of the 25th Annual European Hematology Association Congress:
  • A retrospective analysis of data from the landmark STOP 2 study linking higher Hb levels to lower transcranial Doppler flow velocity, a predictor of stroke risk in children with SCD.
  • Three encore presentations of the pivotal Phase 3 HOPE Study that reinforced key attributes of Oxbryta, including that the lowest incidence of VOCs occurred in patients who achieved the highest Hb levels; that biomarkers of hemolysis decrease with increasing dose; and that the treatment effect seen with Oxbryta was independent of hydroxyurea use.

Corporate

• Announced plans to expand the potential use of Oxbryta for the treatment of SCD in children as young as 4 years old. GBT plans to submit a New Drug Application, which will include a new age-appropriate formulation, to the U.S. Food and Drug Administration by mid-2021.
• Announced plans to seek full marketing authorization in Europe for Oxbryta to treat hemolytic anemia in SCD patients ages 12 years and older. GBT plans to submit a Marketing Authorization Application to the European Medicines Agency by mid-2021.
• Awarded $250,000 in grants to five nonprofit organizations to advance access to care for people living with SCD through the company’s Access to Excellent Care for Sickle Cell Patients (ACCEL) program. The ACCEL program was established by GBT in 2019 to help fund programs that have the potential to deliver high-quality healthcare to people living with SCD.

Financial Results for the Second Quarter 2020
Total net product sales for the second quarter of 2020 was $31.5 million, resulting from sales of Oxbryta. The company did not generate product sales in the second quarter of 2019.

Cost of sales for the three months ended June 30, 2020, was $0.4 million. Manufacturing costs incurred prior to FDA approval of Oxbryta in November 2019 were previously recorded as research and development expense in the company’s consolidated statement of operations. GBT expects that the cost of Oxbryta sales as a percentage of revenue will increase in future periods as product manufactured prior to FDA approval, and therefore fully expensed, is utilized. GBT did not incur cost of sales for Oxbryta in the second quarter of 2019 as no product sales were generated.

Research and development (R&D) expenses for the three months ended June 30, 2020, were $34.1 million compared with $36.0 million for the same period in 2019. The decrease in R&D expenses for this comparative period was primarily attributable to a decrease in manufacturing costs for Oxbryta. Following FDA approval of Oxbryta in November 2019, GBT now capitalizes manufacturing of the product to inventory. The decrease in R&D expenses was partially offset by increased costs related to preclinical research and manufacturing activities for inclacumab, increased employee-related costs, and increased costs for other preclinical research activities related to the collaboration with Syros Pharmaceuticals, Inc. Total R&D non-cash stock compensation expense incurred for the three months ended June 30, 2020, was $3.4 million compared with $4.7 million for the same period in 2019.

Sales, general, and administrative (SG&A) expenses for the three months ended June 30, 2020, were $49.1 million compared with $24.8 million for the same period in 2019. The increase in SG&A expenses for this comparative period was primarily attributable to increased employee-related costs, including non-cash stock compensation expense, and increased professional and consulting services associated with the build-out of the company’s commercial operations and launch of Oxbryta. Total SG&A non-cash stock compensation expense incurred in the three months ended June 30, 2020, was $13.1 million compared with $6.2 million for the same period in 2019.

Net loss for the three months ended June 30, 2020, was $52.8 million compared with $57.3 million for the same period in 2019. Basic and diluted net loss per share for the three months ended June 30, 2020, was $0.86 compared with $1.01 for the same period in 2019. The company expects its operating costs to increase in subsequent quarters due to costs associated with expanding commercialization activities as well as costs associated with the advancement of its clinical pipeline.

Cash, cash equivalents, and marketable securities totaled $574.2 million at June 30, 2020, compared with $695.0 million at December 31, 2019.

About Sickle Cell Disease
Sickle cell disease (SCD) affects an estimated 100,000 people in the United States,¹ an estimated 52,000 people in Europe,² 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 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, people 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) 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. 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 November 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 voxelotor in the HOPE-KIDS 2 Study, a post-approval confirmatory study using transcranial Doppler (TCD) flow velocity to assess the ability of Oxbryta 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. The European Medicines Agency (EMA) has included Oxbryta in its Priority Medicines (PRIME) program, 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 healthcare 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 healthcare 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 healthcare 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 2 weeks after the last dose.

Patients should tell their healthcare 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 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).
