In 2023, Editas Medicine strengthened and focused its discovery organization to build an in vivo gene editing pipeline.

Business Development

In December, Editas Medicine entered into a license agreement with Vertex Pharmaceuticals, providing Vertex a non-exclusive license for the Company's Cas9 gene editing technology for ex vivo gene editing medicines targeting the BCL11A gene in the fields of sickle cell disease and beta thalassemia, including Vertex's CASGEVY™ (exagamglogene autotemcel). Under the terms of the agreement, Editas Medicine received an upfront payment and is eligible to receive an additional $50 million contingent upfront payment as well as annual license fees, which may include certain sales-based annual license fee increases, through 2034.

Fourth Quarter and Full Year 2023 Financial Results

Cash, cash equivalents, and marketable securities as of December 31, 2023, were $427.1 million compared to $446.4 million as of September 30, 2023. The Company expects the existing cash, cash equivalents, and marketable securities together with the near-term annual license fees and the contingent upfront payment payable under our license agreement with Vertex Pharmaceuticals, Incorporated, to fund operating expenses and capital expenditures into 2026.

Fourth Quarter 2023

For the three months ended December 31, 2023, net loss attributable to common stockholders was $18.9 million, or $0.23 per share, compared to net loss of $60.7 million, or $0.88 per share, for the same period in 2022.
Collaboration and other research and development revenues increased to $60.0 million for the three months ended December 31, 2023, compared to $6.5 million for the same period in 2022. The increase was primarily attributable to payments received under our license agreement with Vertex.
Research and development expenses increased by $17.6 million to $69.6 million for the three months ended December 31, 2023, compared to $52.0 million for the same period in 2022. The increase is primarily attributable to sublicense payments made in connection with the Vertex license agreement offset by savings from our re-prioritization and targeted focus on our reni-cel program.
General and administrative expenses decreased by $3.5 million to $14.5 million for the three months ended December 31, 2023, compared to $18.0 million for the same period in 2022. The decrease was primarily driven by reduced patent and legal costs.

Full Year 2023

For the full year 2023, net loss attributable to common stockholders was $153.2 million, or $2.02 per share, compared to $220.4 million, or $3.21 per share, for the same period in 2022.
Collaboration and other research and development revenues were $78.1 million for 2023, compared to $19.7 million for 2022. The $58.4 million increase was primarily attributable to payments received under our license agreement with Vertex.
Research and development expenses increased by $2.7 million to $177.7 million for 2023, compared to $175.0 million for 2022. The increase is primarily attributable to sublicense payments made in connection with the Vertex license agreement, partially offset by decreased external expense resulting from our strategic reprioritization and targeted focus on our reni-cel program.
General and administrative expenses were $69.7 million for 2023, compared to $70.7 million for 2022. The $1.0 million decrease relates to decreased stock compensation expense partially offset by an increase in professional services to support strategic initiatives and business development activities.
