In parallel, the Company is advancing a next-generation LPA program, CTX321™, incorporating an updated guide RNA that demonstrates approximately two-fold greater potency in preclinical testing, while utilizing the same LNP delivery system. CTX321 is currently in IND/CTA-enabling studies, with an Lp(a) program update expected in 2026.
In addition to its clinical-stage programs, CRISPR Therapeutics continues to advance several preclinical in vivo gene editing candidates, including:
- CTX460™, targeting SERPINA1 for the treatment of alpha-1 antitrypsin deficiency (AATD), is the first investigational candidate to emerge from the Company’s SyNTase™ editing platform. The Company expects to initiate a clinical trial for CTX460 in mid-2026.
- CTX340™, targeting angiotensinogen (AGT) for refractory hypertension, is currently in IND/CTA-enabling studies. The Company expects to initiate a clinical trial for CTX340 in the first half of 2026.

siRNA-based Programs
CRISPR Therapeutics’ small interfering RNA (siRNA)-based portfolio includes clinical-stage programs in cardiovascular and thromboembolic diseases, developed in collaboration with Sirius Therapeutics.

CTX611 (SRSD107), a long-acting siRNA targeting Factor XI (FXI), is in an ongoing Phase 2 clinical trial in patients undergoing total knee arthroplasty (TKA). The Company expects to provide an update in the second half of 2026.
CRISPR Therapeutics will lead global Phase 3 development of CTX611, excluding Greater China. The program targets a range of thromboembolic and clotting-related indications and represents a multi-billion-dollar market opportunity, including arterial fibrillation (AF), venous thromboembolism (VTE), ischemic stroke, cancer-associated thrombosis (CAT), chronic kidney disease (CKD), peripheral vascular disease (PVD), chronic coronary artery disease (CAD).

Autoimmune Disease and Immuno-Oncology
Zugocabtagene geleucel (zugo-cel; formerly CTX112™) continues to advance in both autoimmune disease and hematologic malignancies.

In autoimmune disease, Phase 1 clinical trials are ongoing across multiple indications, including systemic lupus erythematosus (SLE), systemic sclerosis (SSc), and inflammatory myositis and a second Phase 1 trial in immune thrombocytopenia purpura (ITP) and warm autoimmune hemolytic anemia (wAIHA). The first patient with SLE, refractory to 9 prior therapies with a baseline Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score of 8, has maintained drug-free DORIS clinical remission through month 9 following CAR-T therapy. The second SLE patient with a baseline SLEDAI-2K score of 8, has sustained B cell depletion with SLEDAI-2K score of 0 through month 2 following CAR-T therapy. The Company expects to provide updates in the second half of 2026.
The Phase 1/2 clinical trial of zugo-cel in B-cell malignancies is ongoing. The Company expects to provide updates in the second half of 2026. CRISPR Therapeutics has also established a collaboration and clinical supply agreement with Lilly to evaluate zugo-cel together with pirtobrutinib in aggressive B-cell lymphomas, further expanding the program’s development in oncology.

Regenerative Medicine
CRISPR Therapeutics continues to advance its regenerative medicine portfolio, including its efforts in diabetes. Clinical data generated from CTX211™ were promising, demonstrating detectable C-peptide levels 12 months after implantation. These data have informed the Company’s approach to hypoimmune cell engineering, supporting a transition to a next-generation candidate, CTX213™. CTX213 has demonstrated compelling preclinical efficacy and is progressing towards the clinic. The Company expects to provide additional updates as development progresses.

About CASGEVY^® (exagamglogene autotemcel [exa-cel])

CASGEVY^® is a non-viral, ex vivo CRISPR/Cas9 gene-edited cell therapy for eligible patients with SCD or TDT, in which a patient’s own hematopoietic stem and progenitor cells are edited at the erythroid specific enhancer region of the BCL11A gene. This edit results in the production of 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. CASGEVY has been shown to reduce or eliminate VOCs for patients with SCD and transfusion requirements for patients with TDT. CASGEVY is approved for eligible SCD and TDT patients 12 years and older by multiple regulatory bodies around the world.

About the CRISPR Therapeutics - Vertex Collaboration for CASGEVY

CRISPR Therapeutics and Vertex established a strategic research collaboration in 2015 to discover and develop therapies using CRISPR/Cas9 technology to address the underlying genetic causes of human disease. CASGEVY is the first approved therapy to emerge from this collaboration. Under an amended collaboration agreement, Vertex leads global development, manufacturing, and commercialization of CASGEVY and shares program costs and profits worldwide 60/40 with CRISPR Therapeutics. Vertex is the manufacturer and exclusive license holder of CASGEVY.

About In Vivo Programs

CRISPR Therapeutics has established a proprietary lipid nanoparticle (LNP) delivery platform to enable gene editing in the liver using both CRISPR/Cas9 and its novel, proprietary SyNTase™ editing technologies. The Company’s in vivo portfolio includes its lead investigational programs, CTX310 (directed towards angiopoietin-related protein 3 (ANGPTL3)) and CTX320 (directed towards LPA, the gene encoding apolipoprotein(a) (apo(a)), a major component of lipoprotein(a) [Lp(a)]). Both are validated therapeutic targets for cardiovascular disease. CTX310 and CTX320 are being developed for patients with heterozygous familial hypercholesterolemia, homozygous familial hypercholesterolemia, mixed dyslipidemias, or severe hypertriglyceridemia, and in patients with elevated lipoprotein(a), respectively. In addition, the Company’s research and preclinical development candidates include: CTX460™, targeting SERPINA1 for the treatment of alpha-1 antitrypsin deficiency (AATD), CTX340™, targeting AGT for the treatment of refractory hypertension and CTX321, targeting LPA for the treatment of patients with elevated lipoprotein(a).

About CTX611 (SRSD107)

CTX611 is a novel double-stranded siRNA, designed to target the human coagulation FXI messenger RNA and inhibit FXI protein expression. Through modulation of the intrinsic coagulation pathway, CTX611 is intended to provide anticoagulant and antithrombotic effects. Supported by clinical experience to date, CTX611 is being developed as a long-acting FXI inhibitor with the potential to support infrequent, including semi-annual, subcutaneous administration.
