Global Blood Therapeutics

Develops and sells sickle cell therapies

Overview

Global Blood Therapeutics develops and delivers treatments for sickle cell disease. Its core product, Oxbryta (voxelotor), is an oral medicine approved by the FDA for SCD patients as young as 4 years old, and the company conducts research, clinical trials, and regulatory work to bring new therapies to market. Oxbryta works by acting on hemoglobin to reduce red blood cell sickling, supporting healthier blood flow. The company differentiates itself through a focused, disease-specific portfolio and active patient advocacy, prioritizing SCD care and community engagement alongside its R&D efforts. Its goal is to change the treatment paradigm for SCD by expanding options, improving outcomes, and progressing toward additional therapies for patients and families affected by the disease.

Simplify's Take

What believers are saying

  • Pfizer still owns GBT601, an oral next-generation HbS inhibitor from GBT’s platform.
  • Pfizer's 2025 THRIVE-131 readout preserved clinical optionality for inclacumab’s open-label extension data.
  • Pfizer’s 2022 purchase gives GBT scientists big-pharma capital, manufacturing, and regulatory infrastructure.

What critics are saying

  • Pfizer withdrew Oxbryta worldwide on September 25, 2024, after deaths and VOC imbalance.
  • Oxbryta litigation in Northern California targets Pfizer and GBT through 2027 bellwether trials.
  • Inclacumab failed THRIVE-131 on August 15, 2025, leaving GBT601 as the last major sickle-cell bet.

What makes Global Blood Therapeutics unique

  • GBT pioneered Oxbryta, the first FDA-approved HbS polymerization inhibitor, before Pfizer's 2022 acquisition.
  • Its sickle-cell expertise still anchors Pfizer’s rare-disease hematology credibility.
  • GBT601 preserved a differentiated oral mechanism after Oxbryta, unlike gene therapies.
