Achieved Oxbryta^® (voxelotor) net revenues of $52.1 million, a 41% increase year over year

Oxbryta sNDA and NDA for pediatric label expansion accepted by FDA for priority review; PDUFA target action date of December 25, 2021

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

SOUTH SAN FRANCISCO, Calif., Nov. 04, 2021 (GLOBE NEWSWIRE) -- Global Blood Therapeutics, Inc. (GBT) (NASDAQ:GBT) today reported financial results for the third quarter ended September 30, 2021 and recent business progress.

"Our third quarter results reflect progress with our ongoing initiatives to drive Oxbryta awareness, adoption and access, and like others in our industry, this was partially offset by the impact of the Delta variant causing a surge in COVID-19 cases in key states. Importantly, we continued to grow the net number of patients on Oxbryta, and the fundamentals of our launch remain strong," said Ted W. Love, M.D., president and chief executive officer of GBT. "Going forward, we have the opportunity to significantly expand the number of patients that potentially may benefit from Oxbryta, including approximately 16,000¹ patients ages 4 to 11 years by end of year if our pediatric label expansion in the U.S. receives approval, and approximately 52,000² patients via a potential marketing authorization in Europe in the first half of 2022."

"We are also advancing a robust R&D pipeline. At the ASH Annual Meeting in December, we will present initial results from our Phase 1 study of GBT601, our next-generation sickle hemoglobin polymerization inhibitor, in both healthy volunteers and sickle cell patients – adding to our confidence in GBT601's potential. We will also report new Phase 1 data on inclacumab at ASH that we believe supports its best-in-class potential as a well-tolerated, quarterly dosed P-selectin inhibitor," added Dr. Love.

Recent Business Progress

Commercial

Achieved Oxbryta^® (voxelotor) net sales of $52.1 million in the third quarter, an increase of 41% year over year. On a sequential basis, sales increased 9.5%, primarily driven by patient demand.
Recorded approximately 850 new prescriptions for Oxbryta in the third quarter.
The net number of patients taking Oxbryta increased compared to the prior quarter and has increased each quarter since launch.
Results in the third quarter reflect headwinds from the spike in new COVID-19 cases in August and September. GBT continues to believe that when the pandemic subsides, the number of new Oxbryta prescriptions will improve incrementally. GBT anticipates that in future periods new prescriptions will eventually surpass pre-COVID-19 levels.
Oxbryta continues to have broad payer coverage, with more than 90% of covered lives having access through their healthcare plans.
Launched the first branded direct-to-consumer television advertising campaign in sickle cell disease (SCD) to educate and empower patients, which exceeded its targeted audience reach in the initial months of the campaign. The commercial can be viewed on Oxbryta.com.
Furthered GBT's education and brand commitment efforts, including the launch of a video titled "Mechanism of Sickle Cell Disease" on SickleCellSpeaks.com, to help people learn about SCD and how it affects the body.
Continued preparations for the potential approval of Oxbryta in the U.S. for children ages 4-11 years, including enrolling patients in GBT's pediatric expanded access protocol (EAP), engaging in medical and scientific education with pediatric hematologists, and educating payers.

It will fund programs that will support people within the SCD community and beyond through education, empowerment, improved healthcare access and enhanced health equity.
GBT and Oxbryta received the prestigious 2021 Prix Galien USA award for "Best Biotechnology Product" from The Galien Foundation. Oxbryta was selected among 19 nominees by a committee of 12 leaders from the biotech industry and academia, including five Nobel Laureates.

Financial Results for the Third Quarter 2021

Total net product sales for the third quarter of 2021 were $52.1 million, resulting from sales of Oxbryta, compared to $36.9 million for the third quarter of 2020.

Cost of sales for the three months ended September 30, 2021, was $0.8 million, compared with $0.5 million for the same period in 2020. 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 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 completely utilized.

Research and development (R&D) expenses for the three months ended September 30, 2021, were $50.5 million, compared with $40.2 million for the same period in 2020. The increase was primarily due to an increase in external costs related to the company's preclinical programs and Oxbryta and inclacumab programs. Total R&D non-cash stock compensation expense incurred for the three months ended September 30, 2021, was $4.6 million, compared with $4.2 million for the same period in 2020.

Sales, general, and administrative (SG&A) expenses for the three months ended September 30, 2021, were $68.0 million, compared with $54.5 million for the same period in 2020. The increase in SG&A expense was primarily attributable to increased professional and consulting services associated with the company's commercial operations for Oxbryta and employee-related costs, including non-cash stock compensation expense. Total SG&A non-cash stock compensation expense incurred in the three months ended September 30, 2021, was $13.5 million, compared with $14.9 million for the same period in 2020.

Net loss for the three months ended September 30, 2021, was $71.0 million, compared with $59.9 million for the same period in 2020. Basic and diluted net loss per share for the three months ended September 30, 2021, was $1.13, compared with $0.97 for the same period in 2020.

Cash, cash equivalents, and marketable securities totaled $416.8 million at September 30, 2021, compared with $560.9 million at December 31, 2020.

About Sickle Cell Disease

Sickle cell disease (SCD) affects an estimated 100,000 people in the United States,³ 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.³ It also affects people of Hispanic, South Asian, Southern European, and Middle Eastern ancestry.³ 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, 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.⁹

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), Oxbryta was designated by the European Commission (EC) as an orphan medicinal product for the treatment of patients with SCD, and Oxbryta was granted Promising Innovative Medicine (PIM) designation in the United Kingdom from the Medicines and Healthcare Products Regulatory Agency (MHRA).

The EMA has accepted for review GBT's Marketing Authorization Application (MAA) seeking full marketing authorization of Oxbryta in the European Union to treat hemolytic anemia in SCD patients ages 12 years and older. GBT is also seeking 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).
