CRISPR Therapeutics AG (NASDAQ:CRSP) on Friday reported its fourth-quarter and full-year 2025 financial results, highlighting continued clinical progress, expanding uptake of Casgevy, and momentum across its gene-editing and RNA-based pipeline.
Casgevy Uptake
Casgevy, the company’s gene-editing therapy for sickle cell disease and transfusion-dependent beta thalassemia, generated $54 million in fourth-quarter revenue and $116 million for the full year.
A total of 64 patients received infusions in 2025, including 30 during the fourth quarter.
Globally, 147 patients initiated treatment through the first cell collection during the year. Patient initiations nearly tripled compared to 2024, reflecting growing momentum heading into 2026.
William Blair noted, “the increase to 147 first cell collections strengthens confidence that higher initiation volumes will translate into materially greater revenue in 2026.”
Access to Casgevy continued to expand across key markets, with reimbursement now covering roughly 90% of eligible patients in the U.S. The therapy is also reimbursed across several European and Middle Eastern markets. In January, partner Vertex Pharmaceuticals Inc. (NASDAQ:VRTX) secured reimbursed access for sickle cell disease patients in Scotland.
Pipeline Advancement
Beyond hematology, the company continues to advance its in vivo liver editing programs.
CTX310 remains in Phase 1b trials targeting lipid disorders, while CTX321, a next-generation Lp(a) program, is progressing through enabling studies with updates expected in the second half of 2026.
William Blair analyst Sami Corwin wrote, “We continue to see the company’s in vivo cardiovascular gene editing programs as meaningful value drivers…”
Corwin added that clinical data for CTX310 look competitive with the LDL-C reductions that have been reported with Arrowhead Pharmaceuticals Inc.’s (NASDAQ:ARWR) AROANG3 and Regeneron Pharmaceuticals Inc.’s (NASDAQ:REGN) Evkeeza, and the reductions in TG potentially set a new bar in the space.
Its siRNA-based candidate CTX611, developed with Sirius Therapeutics, is currently in Phase 2 trials for patients undergoing knee replacement surgery and may have broader applications across thromboembolic diseases.
Zugo-cel is also progressing in autoimmune and oncology indications, including systemic lupus erythematosus and B-cell malignancies. The therapy is being evaluated in combination with pirtobrutinib under an existing collaboration with Eli Lilly and Co. (NYSE:LLY).
CRISPR Therapeutics ended 2025 with $1.98 billion in cash and marketable securities. R&D expenses rose to $83.5 million in the fourth quarter, while net loss widened to $130.6 million in the fourth quarter from $37.3 million a year earlier.
CRSP Price Action: CRISPR Therapeutics shares were up 8.81% at $53.24 at the time of publication on Friday, according to Benzinga Pro data.
