Also known as: Sirius Therapeutics
Sirius Therapeutics is a global clinical-stage biotechnology company focused on siRNA therapeutics for chronic diseases. It develops first-in-class and best-in-class siRNA medicines across coagulation disorders, cardiometabolic diseases, and obesity.
CRISPR Therapeutics reported a $581.6 million net loss in 2025 with revenue of just $3.5 million, while continuing to advance its gene-editing pipeline including the approved CASGEVY therapy and next-generation CAR T cell programs. The company maintains strategic partnerships and expects current funds to support operations for at least 24 months.
CRISPR Therapeutics reported a Q4 2025 loss of $1.37 per share, missing estimates, with revenues of $0.9 million falling short of expectations. The company's partner Vertex recorded $54 million in Casgevy sales for the quarter, with regulatory submissions for pediatric label expansion planned for early 2026.
The FDA has issued draft guidance that may speed approval pathways for rare disease therapies using genome editing technologies, potentially benefiting CRISPR Therapeutics' pipeline of six clinical-stage candidates.
Switzerland-based CRISPR Therapeutics stands to benefit from increased Casgevy sales following partner Vertex Pharmaceuticals' fourth-quarter results, with five additional gene-editing therapies in clinical trials targeting larger patient populations.
Vertex Pharmaceuticals and CRISPR Therapeutics reported $116 million in full-year 2025 sales for gene-editing therapy Casgevy, with 64 patients receiving infusions and patient initiations nearly tripling compared to 2024.
