Breaking Down Global Blood Therapeutics, Inc. (GBT) Financial Health: Key Insights for Investors

Born in 2011 and headquartered in South San Francisco, Global Blood Therapeutics built a focused mission to transform care for sickle cell disease (SCD) and other underserved blood-based disorders, culminating in the development of Oxbryta® (voxelotor)-the first FDA‑approved therapy that directly inhibits sickle hemoglobin polymerization with FDA approval in 2019-and driving a vision of scientific innovation, patient-centric care and health equity that attracted acquisition by Pfizer in October 2022 for approximately $5.4 billion, underscoring GBT's commitment to research, collaboration with clinicians and patient communities, and delivering medicines to populations historically lacking access.

Global Blood Therapeutics, Inc. (GBT) - Intro

• Founded: 2011 (South San Francisco, CA)
• Lead product: Oxbryta® (voxelotor) - first direct hemoglobin polymerization inhibitor approved by FDA (October 2019)
• Acquisition: October 2022 - acquired by Pfizer Inc. (integrated into Pfizer's Rare Disease portfolio)

• Mission: Transform the treatment and care of sickle cell disease by developing therapies that address disease biology and improve patient outcomes and quality of life.
• Vision: Be a leader in therapies for serious blood-based disorders, prioritizing innovation for underserved patient populations.

• Patient-centricity - prioritizing measurable clinical benefit and quality-of-life improvements for SCD patients.
• Science-driven innovation - focusing on mechanisms that target root causes (e.g., HbS polymerization).
• Equity and access - addressing unmet needs in historically underserved communities affected by SCD.
• Collaboration - partnering with clinicians, patient advocacy groups, and industry partners to accelerate impact.

• HOPE Phase 3 trial (voxelotor): primary endpoint met with a clinically meaningful hemoglobin increase (≈51% achieving ≥1.0 g/dL vs ≈7% placebo), along with improvements in hemolysis biomarkers.
• Regulatory pathway: Oxbryta received accelerated approval pathways and subsequent regulatory actions supporting its role as a disease-modifying therapy for SCD.

• Commercial focus: Oxbryta commercialization and access programs aimed at broadening treatment availability for SCD patients in the U.S. and select international markets.
• Acquisition outcome: In October 2022 Pfizer acquired GBT for approximately $5.4 billion, integrating GBT's assets into Pfizer's Rare Disease portfolio to scale reach and development.

Global Blood Therapeutics, Inc. (GBT) - Overview

• Mission focus: develop innovative therapies addressing underlying causes of SCD and related hemoglobinopathies, improving patient outcomes and daily quality of life.
• Health equity commitment: prioritize access for communities of color disproportionately affected by SCD.
• R&D emphasis: sustained investment in discovery and clinical development to advance disease-modifying treatments.
• Value orientation: align therapeutic advances with outcomes that deliver durable benefit to patients and communities.

• Clinical innovation - advancing mechanisms that target hemoglobin polymerization, hemolysis, and downstream organ damage.
• Patient access & equity - programs to reduce financial and structural barriers, clinician education, and community outreach in disproportionately affected populations.
• Evidence generation - robust trials (e.g., HOPE) and real-world studies to quantify clinical benefit, safety, and longer-term outcomes.
• Partnerships & scale - leveraging collaborations and, ultimately, integration into larger biopharma to expand research capacity and global reach.

• Clinical development: HOPE pivotal data demonstrating hematologic benefit and reductions in hemolysis markers provided regulatory and payer evidence.
• Access initiatives: targeted programs to improve diagnosis, referral and treatment continuity in underserved communities.
• Scientific pipeline: development efforts extending from voxelotor's mechanism to broader approaches to modify disease biology.

Global Blood Therapeutics, Inc. (GBT) - Mission Statement

• Develop and deliver disease-modifying therapies that address the root causes of SCD and other severe hematologic disorders.
• Advance health equity by striving to ensure patients of all backgrounds can access effective treatments.
• Invest substantially in rigorous clinical development and translational science to convert novel biology into approved medicines.
• Partner with patient communities, clinicians, payers, and policy stakeholders to optimize real-world impact and access.

• Leadership in therapy development for blood-based disorders - GBT prioritized first-in-class approaches targeting disease biology rather than only symptom control.
• Transforming the SCD treatment landscape - realized through development and approval of voxelotor (Oxbryta®), a therapy designed to inhibit hemoglobin polymerization and reduce hemolysis.
• Commitment to health equity - public-facing programs and community engagement focused on historically underserved SCD populations.
• Meaningful patient impact - clinical data and post-approval outcomes intended to improve hemoglobin levels, reduce hemolysis markers, and enhance quality of life.
• Substantial R&D commitment - continuous investment in clinical trials, regulatory strategy, and lifecycle expansion to broaden indications and age groups.

• R&D focus: robust randomized controlled trials (e.g., HOPE), longitudinal safety and real-world evidence generation to demonstrate clinical benefit and inform guideline adoption.
• Access strategies: payer engagement, patient support programs, and policy initiatives to reduce barriers to therapy for underserved populations.
• Outcome orientation: measuring hemoglobin improvements, reductions in markers of hemolysis, frequency of vaso-occlusive crises in longer-term studies, and quality-of-life endpoints.

Global Blood Therapeutics, Inc. (GBT) - Vision Statement

• Health equity: ensure treatments reach underserved and high-burden communities globally, reducing disparities in access and outcomes.
• Scientific innovation: push disease-modifying therapies from discovery to approval through rigorous clinical development.
• Patient-centric care: prioritize clinically meaningful endpoints (hemoglobin improvement, reduced hemolysis, fewer vaso-occlusive crises) and patient-reported outcomes.
• Collaborative partnerships: engage clinicians, patient organizations, payers, and research institutions to accelerate adoption and disseminate best practices.
• Ethical standards and transparency: maintain integrity in clinical data reporting, regulatory interactions, and commercial practices.

• Global SCD prevalence: estimated 20-25 million people worldwide, with the greatest burden in sub-Saharan Africa, India, and parts of the Middle East.
• U.S. prevalence: roughly 90,000-100,000 people living with SCD.
• Clinical impact metrics (from pivotal HOPE trial of voxelotor): N ≈ 274; 51% of patients treated achieved ≥1.0 g/dL increase in hemoglobin versus 7% with placebo; meaningful reductions in markers of hemolysis were observed.
• Regulatory milestone: voxelotor (Oxbryta) received accelerated FDA approval in 2019 for the treatment of SCD in patients aged 12 and older, forming a cornerstone of GBT's portfolio and strategic vision.

• Clinical programs prioritized endpoints directly tied to patient function and survival (hemoglobin, hemolysis markers, vaso-occlusive crisis rates).
• Access initiatives targeted insurer coverage, real-world evidence generation, and programs to reach underserved populations.
• Collaborations with patient advocacy groups and academic centers supported recruitment diversity in trials and dissemination of educational materials.
• Transparency practices included peer‑reviewed publication of trial results, public regulatory filings, and clear safety/efficacy communications to providers and patients.
