Press Release

Achieved Oxbryta^® (voxelotor) net revenues of $41.3 million in the fourth quarter and $123.8 million for full year 2020

Further established leadership in sickle cell disease (SCD) with data presentations on pipeline programs inclacumab and GBT021601 (GBT601)

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

SOUTH SAN FRANCISCO, Calif., Feb. 24, 2021 (GLOBE NEWSWIRE) -- Global Blood Therapeutics, Inc. (GBT) (NASDAQ: GBT) today reported recent business progress and financial results for the fourth quarter and year ended December 31, 2020.

“In 2020, GBT adapted to the challenging conditions of the global COVID-19 pandemic to safely and successfully execute the launch of Oxbryta. It is a testament to our team’s dedication and the need for innovative therapies for sickle cell disease that we ended the year with thousands of patients on Oxbryta, an established base of prescribers, broad payer coverage, and a growing body of real-world evidence demonstrating statistically significant decreases in VOCs and transfusions and improved overall health-status. In addition, we announced robust progress for our pipeline with plans to advance inclacumab and GBT601 in 2021. We believe both these programs have the potential to become best-in-class SCD therapies, further expanding our leadership in SCD,” said Ted W. Love, M.D., president and CEO of GBT.

“We continue to be confident in the long-term potential of Oxbryta and are well positioned to build on our strong fundamentals to enhance our commercialization efforts in the U.S. and accelerate adoption. Furthermore, we continue to make important progress on our goal to provide access to Oxbryta to more SCD patients. We will also continue to support the SCD community and efforts to improve access to care, which has become even more important because of the impact of the COVID-19 pandemic that has dramatically magnified long-standing health inequities,” added Dr. Love.

Recent Business Progress

Commercial

• Achieved Oxbryta^® (voxelotor) tablets net sales of $41.3 million and $123.8 million in the three and twelve months ended December 31, 2020, respectively.
• Recorded approximately 950 new prescriptions of Oxbryta in the fourth quarter of 2020, despite a dramatic increase in COVID-19 cases in the U.S. during this period.
• New prescriptions in the fourth quarter of 2020 reflect ongoing increases in the use of telemedicine by healthcare providers, partially offset by fewer healthcare provider and patient interactions due to the increase in COVID-19 cases in the United States, and the Thanksgiving and Christmas holidays. GBT continues to believe that when the pandemic subsides, the number of new prescriptions will further improve and surpass pre-COVID-19 levels over time.
• Continued to secure Oxbryta reimbursement coverage, with more than 90% of lives covered by payers either through published policies or verified patient adjudication by the end of the fourth quarter. GBT has secured fee-for-service Medicaid coverage in 47 states, including all 17 priority states where most SCD patients live.
• In February 2021, GBT launched patient starter kits and new sales materials in the U.S. to provide deeper education on Oxbryta and launched www.gbtsource.com, which provides information for patients, caregivers and health professionals on GBT Source Solutions^® -- the company’s dedicated SCD patient support program that helps eligible patients start and stay on Oxbryta.
  

Clinical

• Presented nine posters at the American Society of Hematology (ASH) Annual Meeting & Exposition in December 2020, including the 72-week analysis of the completed Phase 3 HOPE Study and data on real-world experience with Oxbryta. The ASH presentations also included preclinical data on the company’s promising SCD pipeline, including inclacumab, a P-selectin inhibitor with potential to deliver more potency and once-quarterly dosing for a best-in-class profile, and GBT601, a next generation hemoglobin S polymerization inhibitor with increased potency and the potential to provide a functional cure for SCD.
• Announced plans to initiate two global, randomized, placebo-controlled pivotal Phase 3 trials evaluating the safety and efficacy of inclacumab in the first half of 2021. One trial will focus on the reduction in VOCs and the second will focus on reducing 90-day hospital readmission following an initial VOC hospitalization.
• In December 2020, initiated a first-in-human Phase 1 study on the safety and tolerability of GBT601 in healthy volunteers. In 2021, GBT plans to begin studying GBT601 in SCD patients, with a goal of providing proof-of-concept data by the end of the year.
• In January 2021, a post hoc analysis that evaluated the incidence of leg ulcers and outcomes in patients enrolled in the HOPE trial across the 72-week treatment period was published in the American Journal of Hematology. The study findings add to the growing body of evidence of the potential clinical benefits of Oxbryta.
• In January 2021, enrolled the first patient in an expanded access protocol (EAP) in the U.S. for Oxbryta in pediatric patients with SCD. The EAP provides access for children ages 4 to 11 years who have no alternative treatment options and are ineligible to participate in clinical trials of Oxbryta.
• Initiated an early access program for voxelotor in Europe and other regions outside the United States in December 2020, allowing physicians in countries with an early access regulatory and legal pathway the option to request voxelotor for eligible SCD patients who do not have access to the medicine as part of a clinical trial.

Corporate

• Strengthened the company’s senior leadership team with the appointment of Kim Smith-Whitley, M.D., as executive vice president and head of research and development. Dr. Smith-Whitley is a board-certified pediatric hematologist and clinical director of hematology and director of the Comprehensive Sickle Cell Center at Children’s Hospital of Philadelphia. Dr. Smith-Whitley will officially join GBT in May 2021, and in the interim, is serving in an advisory capacity.
• In January 2021, GBT announced that the European Medicines Agency (EMA) completed the validation of the company’s Marketing Authorization Application (MAA) for Oxbryta and started its standard review process. GBT is seeking full marketing approval for Oxbryta from the EMA to treat hemolytic anemia in patients with SCD 12 years of age and older.
• GBT was included in the 2021 Bloomberg Gender-Equality Index (GEI). The GEI measures gender equality across five pillars: female leadership and talent pipeline, equal pay and gender pay parity, inclusive culture, sexual harassment policies, and pro-women brand. GBT was one of only 380 companies across 11 sectors, including one of 22 in healthcare, that were included in this index.
• Supported the launch of Life Science Cares (LSC) Bay Area, a nonprofit that empowers corporations within the Life Sciences Industry to help end poverty. Dr. Love is a co-founder of LSC Bay Area and serves as a member of its Board of Managers.

Financial Results for the Fourth Quarter and Year-End 2020
Total net product sales for the fourth quarter of 2020 was $41.3 million, resulting from sales of Oxbryta, compared with $2.1 million for the same period in 2019. Net product sales resulted from sales of Oxbryta, which was launched in the United States in December 2019. Total net product sales for the full year 2020 was $123.8 million, compared with $2.1 million for the same period in 2019.

Cost of sales for the three months ended December 31, 2020, was $1.0 million compared with $48,000 for the same period in 2019. Total cost of sales for the full year 2020 was $2.0 million, compared with $48,000 for the same period in 2019. 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.

Research and development (R&D) expenses for the three months ended December 31, 2020, were $41.1 million compared with $65.0 million for the same period in 2019. R&D expense in the fourth quarter 2019 included a $20 million upfront expense incurred in December 2019 related to the company’s Syros collaboration agreement. Excluding this expense, the decrease in R&D expense compared to the prior year was primarily due to lower expense as a result of capitalization of Oxbryta manufacturing costs to inventory, which was partially offset by higher pre-clinical development activities under the Syros collaboration and other clinical programs. Following FDA approval of Oxbryta in November 2019, GBT capitalizes manufacturing of Oxbryta to inventory. R&D expenses for the year ended December 31, 2020, were $155.1 million compared with $174.6 million for the same period in 2019. The year-over-year decrease was primarily due to a $33.9 million decrease in Oxbryta related manufacturing costs and medical affairs costs that were previously expensed to R&D and a $1.7 million decrease in other preclinical programs. The decrease was partially offset by a $16.3 million increase in external costs associated with inclacumab and driven by the manufacturing activities. Total R&D non-cash stock compensation expense incurred for the three months ended December 31, 2020, was $3.7 million compared with $5.3 million for the same period in 2019. Total R&D non-cash stock compensation expense incurred for the year ended December 31, 2020, was $18.1 million compared with $19.1 million for the same period in 2019.

Selling, general and administrative (SG&A) expenses for the three months ended December 31, 2020, were $58.6 million compared with $44.6 million for the same period in 2019. SG&A expenses for the year ended December 31, 2020, were $210.9 million compared with $117.1 million for the same period in 2019. The increase in SG&A expenses for both comparative periods 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 December 31, 2020, was $14.3 million compared with $7.5 million for the same period in 2019. Total SG&A non-cash stock compensation expense incurred in the year ended December 31, 2020, was $53.4 million compared with $26.5 million for the same period in 2019.

A non-cash gain on the company’s lease modification for the year ended December 31, 2020, was $1.0 million compared with $8.3 million for the same period in 2019. This is a non-recurring item related to the move to the company’s new headquarters in 2020 and related termination of its previous lease in 2019.

Net loss for the three months ended December 31, 2020, was $61.8 million compared with $96.0 million for the same period in 2019. Basic and diluted net loss per share for the three months ended December 31, 2020, was $1.00 compared with $1.59 for the same period in 2019. Net loss for the year ended December 31, 2020, was $247.6 million compared with $266.8 million for the same period in 2019. Basic and diluted net loss per share for the year ended December 31, 2020, was $4.04 compared with $4.57 for the same period in 2019. The company expects its operating costs to increase during 2021 due to costs associated with expanding commercialization activities related to Oxbryta and the advancement of its clinical pipeline.

Cash, cash equivalents, and marketable securities totaled $560.9 million at December 31, 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 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) 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, 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 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 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.

The EMA has accepted for review GBT’s MAA seeking full marketing authorization of Oxbryta in the European Union 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.

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).
