Full analysis, sources & comparables →

Vertex and CRISPR Therapeutics entered a strategic collaboration to use CRISPR/Cas9 gene editing for hemoglobinopathies (sickle cell disease and beta-thalassemia). This led to the development and 2023 FDA approval of Casgevy (exagamglogene autotemcel), the first CRISPR-based gene therapy approved in the US.

Key facts

Disease & market context

Sickle Cell Disease (Gene Therapy)

2K US cases/yr · $1.5B Projected SCD Gene Therapy Market (2025)

Disease Overview

Casgevy uses CRISPR/Cas9 to edit patients' stem cells, reactivating fetal hemoglobin to prevent sickling. It was the first CRISPR-based gene therapy approved by the FDA (Dec 2023).

Historic Significance

Casgevy (exa-cel, Vertex/CRISPR) competes directly with Lyfgenia (lovo-cel, bluebird bio), a lentiviral gene therapy approved same-day (Dec 2023). Non-gene-therapy SCD options include hydroxyurea, Oxbryta (voxelotor, Pfizer; withdrawn 2024), Adakveo (crizanlizumab, Novartis), and Endari (L-glutamine, Emmaus Medical). Stem cell transplant remains the only other curative option.

Beta-Thalassemia (Gene Therapy)

300 US cases/yr · $600M Projected TDT Gene Therapy Market (2025) · 15-20 Annual Transfusions for TDT Patients

Disease Overview

Transfusion-dependent beta-thalassemia requires lifelong blood transfusions and iron chelation. Casgevy offers a potential one-time functional cure through CRISPR editing of the BCL11A erythroid enhancer.

Competitive Landscape

Casgevy competes with Bluebird Bio's Zynteglo (lentiviral gene therapy for TDT, approved 2022). Both require myeloablative conditioning.
