Access to advanced therapies proved to be a major talking point at a conference in London, following the U.S. approval of Bluebird Bio Inc.’s Zynteglo (betibeglogene autotemcel) cell-based gene therapy for beta thalassemia and its $2.8 million price tag. Regulators in Europe backed Zynteglo in 2019 but Bluebird opted to withdraw the therapy in 2021 after deciding that the complex thicket of pricing bodies in Europe was too difficult to negotiate.

Bluebird Bio Inc. isn’t giving out much of the information on the margins for the cost of its newly approved cell-based gene therapy for treating adult and pediatric patients with beta-thalassemia.

Pfizer Inc. plans to pay about $5.8 billion – total equity value – for Global Blood Therapeutics Inc. (GBT) and its oral sickle cell disease (SCD) treatment Oxbryta (voxelotor). The company reported the enterprise value as $5.4 billion, which includes debt and net cash. If completed, the GBT buy would be the second largest M&A in 2022 after Pfizer’s $6.7 billion buyout of Arena Pharmaceuticals Inc. Oxbryta, which netted about $195 million in sales in 2021, gained U.S. FDA approval in November 2019 for the treatment of SCD in adults and pediatric patients ages 12 and up. The FDA later expanded Oxbryta’s approved uses to SCD patients 4 years of age and older in December 2021.
