Pfizer, an American multinational pharmaceutical and biotechnology corporation, completed the acqusition of Global Blood Therapeutics, a biopharmaceutical company dedicated to the discovery, development and delivery of life-changing treatments that provide hope to underserved patient communities, starting with sickle cell disease, for $5.4bn. "Sickle cell disease is the most common inherited blood disorder, and it disproportionately affects people of African descent. We are excited to welcome GBT colleagues into Pfizer and to work together to transform the lives of patients, as we have long sought to address the needs of this underserved community. The deep market knowledge and scientific and clinical capabilities we have built over three decades in rare hematology will enable us to accelerate innovation for the sickle cell disease community and bring these treatments to patients as quickly as possible," Albert Bourla, Pfizer Chairman and CEO.
