Third Quarter 2023 Financial Results 

• Cash Position: Cash, cash equivalents, and marketable securities were $1,739.8 million as of September 30, 2023, compared to $1,868.4 million as of December 31, 2022. The decrease in cash of $128.6 million was primarily driven by operating expenses, offset by payments received from Vertex in connection with a non-exclusive license agreement and related milestone, as well as interest income.
• R&D Expenses: R&D expenses were $90.7 million for the third quarter of 2023, compared to $116.6 million for the third quarter of 2022. The decrease in R&D expense was primarily driven by reduced variable external research and manufacturing costs.
• G&A Expenses: General and administrative expenses were $18.3 million for the third quarter of 2023, compared to $27.0 million for the third quarter of 2022. The decrease in G&A expense was primarily driven by a decrease in external professional costs.
• Collaboration Expense: Collaboration expense, net, was $23.4 million for the third quarter of 2023, compared to $38.9 million for the third quarter of 2022. The decrease of approximately $15.5 million in collaboration expense, net, was due to the fact that we reached the $110.3 million deferral limit on costs related to the exa-cel program in the third quarter of 2023, whereas the limit was not reached until the fourth quarter of 2022.
• Net Loss: Net loss was $112.2 million for the third quarter of 2023, compared to a net loss of $174.5 million for the third quarter of 2022.

About exagamglogene autotemcel (exa-cel)
Exa-cel is an investigational, autologous, ex vivo CRISPR/Cas9 gene-edited cell therapy that is being evaluated for patients with SCD or TDT, in which a patient’s own hematopoietic stem cells are edited to produce high levels of fetal hemoglobin (HbF; hemoglobin F) in red blood cells. HbF is the form of the oxygen-carrying hemoglobin that is naturally present during fetal development, which then switches to the adult form of hemoglobin after birth. The elevation of HbF by exa-cel has the potential to reduce or eliminate painful and debilitating VOCs for patients with SCD and alleviate transfusion requirements for patients with TDT. Earlier results from these ongoing trials were published in The New England Journal of Medicine in January of 2021 and presented at the American Society of Hematology Annual Congress in 2022 and the European Hematology Association Annual Meeting in 2023.

Exa-cel has been granted Regenerative Medicine Advanced Therapy (RMAT), Fast Track, Orphan Drug, and Rare Pediatric Disease designations from the U.S. FDA for both TDT and SCD. The FDA has accepted the Biologics License Applications (BLAs) for exa-cel and assigned Prescription Drug User Fee Act (PDUFA) action dates of December 8, 2023, for SCD and March 30, 2024, for TDT.

In the EU, exa-cel has been granted Orphan Drug Designation from the European Commission, as well as Priority Medicines (PRIME) designation from the European Medicines Agency (EMA), for both SCD and TDT. In the U.K., exa-cel has also been granted an Innovation Passport under the Innovative Licensing and Access Pathway (ILAP) from the Medicines Healthcare products Regulatory Agency (MHRA). In Europe, the Marketing Authorization Applications (MAAs) for exa-cel were submitted in December 2022 and validated by the EMA and MHRA in January 2023.
